Description

[Detailed description of the invention]

The present invention relates to a novel adhesive resin composition. More specifically, the present invention relates to a resin composition characterized by its adhesion to synthetic resins such as polyvinyl chloride resins and polyester resins, and metals, as well as its water resistance. In general, thermoplastic copolymerized polyester resins are
It is widely used in various paints and adhesives because it has excellent flexibility, weather resistance, and excellent adhesion to various base materials. Among others, polyester resins, soft and hard polyvinyl chloride resins,
It is known to have excellent adhesion to synthetic resins such as polycarbonate resin, ABS resin, and polyurethane resin. It also has adhesive properties to metals such as aluminum, lead, and iron, but this is not necessarily as satisfactory as the adhesive properties to the synthetic resins mentioned above. Therefore, if a laminate of synthetic resin and metal is manufactured using thermoplastic copolymerized polyester resin alone as an adhesive, it is difficult to obtain a laminate of synthetic resin and metal that is sufficiently satisfactory for practical use. There is a strong desire to develop a resin with well-balanced and high adhesive properties. In addition, thermoplastic copolymer polyester resins can be made into films and processed by molding and processing methods used for general plastics (inflation method, T-die extrusion method, extrusion lamination method, coextrusion method, etc.).
When laminating on a base material such as metal, it sticks to the cooling roll and cannot be peeled off, making it impossible to mold or process, or even if it can be molded or processed, the film has a large amount of blocking.
Once the film has been wound into a coil, if a laminate is to be produced again using an offline method, it is difficult to unwind the film, resulting in poor crimp workability. Therefore, there is a strong desire to develop a resin that has excellent moldability and processability and less film blocking. In view of these circumstances, the present inventors have developed a film that maintains the unique adhesion of thermoplastic copolyester resin to various synthetic resins, has high adhesion to metals, has excellent moldability and processability, and The present invention was developed as a result of extensive research into an adhesive resin that exhibits less blocking and good water resistance retention. That is, the present invention uses a thermoplastic copolyester resin (A) and an ethylene copolymer containing a functional group.
In an adhesive resin composition prepared by melt-mixing (B) and, if necessary, another type of thermoplastic resin (C), the thermoplastic copolymerized polyester resin (A) is 40 to 80% by weight, and (B) and The total amount of (C) is 60 to 20% by weight, and the thermoplastic copolymerized polyester resin (A) contains 60 to 95 mol% of terephthalic acid and 40 to 5 mol% of isophthalic acid as dicarboxylic acid components, and low molecular weight glycol. 1,4-butanediel as a component 55-95 mol%
and diethylene glycol in an amount of 45 to 5 mol%, and polytetramethylene glycol with a molecular weight of 600 to 6,000 based on the total dicarboxylic acid.
Consisting of 4 mol%, melting point 100-150℃, reduced viscosity
Ethylene copolymer (B) which is a thermoplastic copolymerized polyester resin of 0.5 or more and contains a functional group.
However, melt index 0.5 to 50g/10 minutes (JIS
K6760), α, β unsaturated glycidyl ester,
1 selected from α,β unsaturated glycidyl ethers, α,β unsaturated carboxylic acids and their anhydrides
The present invention relates to an adhesive resin composition characterized in that it is an ethylene copolymer containing 0.01 to 20 mol% of one or more functional groups. The present invention will be explained in detail below. The thermoplastic copolyester resin (A) used in the present invention has a dicarboxylic acid component consisting of 60 to 95 mol% of terphthalic acid and 40 to 5 mol% of isophthalic acid. When the amount of terephthalic acid is less than 60 mol%, the melting point of the polyester produced is
The temperature is less than 100°C, which is disadvantageous from the viewpoint of blocking resistance and easy processability, which are characteristics of the composition according to the present invention. On the other hand, as a low molecular weight glycol component, 1,
Consists of 55 to 95 mol% of 4-butanediol and 45 to 5 mol% of diethylene glycol, and further contains 0.1 to 4 mol% of polytetramethylene glycol with a molecular weight of 600 to 6000 based on the total dicarboxylic acid component.
Consisting of If the content of 1,4-butanediol is less than 55 mol%, the crystallinity of the resulting polyester will decrease and the melting point will become less than 100°C, which is not preferable. Specifically, the melting point of the polyester produced is 100
The combination of these dicarboxylic acid components and glycol components can be freely selected and designed within the above range so that the temperature falls within the range of ~150°C. As mentioned above, the thermoplastic copolyester resin (A) of the present invention has a melting point of 100 to 150°C. When the temperature exceeds 150°C, the adhesion and processability, which are characteristics of the composition according to the present invention, are poor, and the temperature exceeds 100°C.
If the temperature is below .degree. C., a blocking-free film cannot be obtained even with the composition of the present invention. Further, the thermoplastic copolyester resin (A) suitable for the composition according to the present invention has a reduced viscosity of 0.5.
The above are used. If the reduced viscosity is less than 0.5, the mechanical properties of the composition according to the present invention will deteriorate, and not only will sufficient mounting force not be obtained, but it will also be disadvantageous in terms of blocking resistance and ease of processing. The ethylene copolymer (B) containing a functional group used in the present invention can be copolymerized with ethylene and ethylene having the above-mentioned functional group by a known method such as a high-pressure radical polymerization method, a solution polymerization method, or an emulsion polymerization method. monomer, α, β-unsaturated glycidyl ester, α,

In addition to the above components, unsaturated ester monomers such as methyl acrylate, ethyl acrylate, methyl methacrylate, butyl acrylate and other unsaturated carboxylic acid esters and vinyl acetate propionate are added as a third component. Copolymers obtained by copolymerizing or graft polymerizing unsaturated vinyl esters such as vinyl esters can also be used. The melt index of the ethylene copolymer (B) may be within a range that is easy to process, and is 0.5 to 50 g/10 minutes. Different types of thermoplastic resins used in the present invention

Or two or more types of resins. The vinyl aromatic hydrocarbon polymer, which is one of the thermoplastic resins (C), is a single or copolymer of vinyl aromatic hydrocarbons having 8 to 20 carbon atoms, particularly 8 to 12 carbon atoms. Specifically, polystyrene, poly-α-methylstyrene, polyvinyltriene, poly-β-
These include methylene styrene, styrene-acrylonitrile copolymer, styrene-acrylonitrile butadiene copolymer, and the like. A preferred vinyl aromatic hydrocarbon polymer is polystyrene. The (meth)acrylic acid ester polymer, which is one of the thermoplastic resins (C), has the general formula (However, in the formula, R ₁ is hydrogen or a methyl group, and R ₂ is an alkyl group having 1 to 4 carbon atoms.)
Specifically, they include methyl acrylate polymer, methyl methacrylate polymer, ethyl acrylate polymer, butyl acrylate polymer, methyl methacrylate-butyl acrylate copolymer, and the like. In the present invention, the most preferred (meth)acrylic acid ester polymers are methyl methacrylate polymers and copolymers mainly composed of methyl methacrylate.
The (meth)acrylic acid ester polymer may be one further copolymerized with other unsaturated monomers such as styrene, acrylonitrile, etc. The ethylene polymer, which is one of the thermoplastic resins (C), is at least one polymer selected from polyethylene and ethylene-unsaturated ester copolymers. The method for producing these polymers is not particularly limited, and known methods such as high-pressure radical polymerization, solvent polymerization, and solution polymerization can be applied. Ethylene-
Examples of unsaturated ester copolymers include ethylene-vinyl ester copolymers such as ethylene-vinyl acetate copolymer, ethylene-vinyl propionate copolymer, ethylene-methyl methacrylate copolymer, and ethylene-methyl acrylate copolymer. Examples include ethylene-unsaturated carboxylic acid ester copolymers such as polymers, ethylene-ethyl acrylate copolymers, and ethylene-butyl acrylate copolymers. When this ethylene polymer is a copolymer, its ethylene content is 50 mol% or more, preferably 70 mol% or more.

These include ethylene-isobutylene copolymer rubber, attacking polypropylene, and the like. Among these, ethylene-propylene copolymer rubber, ethylene-propylene-nonconjugated diene copolymer rubber, and ethylene-butene copolymer rubber are particularly preferred. The proportions of each component in the adhesive resin composition of the present invention are:
Thermoplastic copolyester resin (A) component is 40 to 80

In addition, the total amount of the ethylene copolymer (B) component and the thermoplastic resin (C) component is less than 20% by weight, and the thermoplastic copolymer polyester resin
When the content of component (A) exceeds 80% by weight, not only is no effect of improving adhesion to metals, but also the extrusion processability of the thermoplastic copolyester resin (A) and the blocking property of the film cannot be improved. Furthermore, in a composition of a thermoplastic copolyester resin (A) component and a thermoplastic resin (C) component to which the ethylene copolymer (B) component is not added, the adhesion to various substrates is reduced. In the adhesive resin composition of the present invention, an improvement effect is observed even in a composition of a thermoplastic copolyester resin (A) and an ethylene copolymer (B); The improvement effect is greater when a composition consisting of one or more types of copolymer (B) and thermoplastic resin (C) is used. That is,
By adding one or more thermoplastic resins (C), the effect of improving extrusion processability, blocking properties of the film, and adhesion to metals is remarkable. In particular, a combination of at least one selected from vinyl aromatic hydrocarbon polymers, (meth)acrylic acid ester polymers, or polyolefin elastomers and at least one selected from ethylene polymers is used. is preferred. The addition of vinyl aromatic hydrocarbon polymers, (meth)acrylic acid ester polymers, and polyolefin elastomers is very effective in achieving the objectives of the present invention, but if too much is added, problems may occur during processing. properties and film strength are reduced. Therefore, by further adding an ethylene polymer, flowability and film strength during processing can be appropriately controlled.
