A kind of paper-plastic package heat-seal adhesive and preparation method thereof
Technical field
The present invention relates to a kind of heat-seal adhesive, more particularly, is a kind of paper-plastic package heat-seal adhesive and preparation method thereof.
Background technology
Packaging industry is on a grand scale in China, and during packaging, paper bonding, the bonding of paper paper, ironshaper bonding, all need for packing glue, the problems such as existing packaging heat-seal adhesive exists poisonous dissolvent residual more, and bonding strength is not high.The harmless bonding needs of present packaging can not be met.
Summary of the invention
The object of this invention is to provide a kind of paper-plastic package heat-seal adhesive and preparation method thereof.
The technical solution adopted in the present invention is:
A kind of paper-plastic package heat-seal adhesive, is characterized in that being made up of the raw material of following weight part:
E-12 epoxy resin 12-14, terpine resin 6-8, EVA resin 14-17, ethyl acetate 12-13, N-BUTYL ACETATE 20-23, tributyl citrate 4-6, phenyl-trichloro-silicane 3-4, MALEIC ANHYDRIDE 6-9, propylene glycol 4-6, titanate coupling agent TMC-TTS1-2, cyclohexanone peroxide 1-2,2-amino-2-methyl-1-propanol 7-9, vinyl triamine 3-4, tackifying assistant 4-5.
Described tackifying assistant is obtained by the raw material of following weight part: thermoplastic acrylic resin 3-4, Silane coupling agent KH550 1-2,582-2 aminoresin 3-4, polyisobutene 2-3, N-BUTYL ACETATE 6-8, cobalt naphthenate 0.1-0.2, biscyclo pentadienyl iron 0.4-0.6;
Preparation method is: join in N-BUTYL ACETATE by thermoplastic acrylic resin, 582-2 aminoresin, so enter to add Silane coupling agent KH550, be heated to 90-100 DEG C, stirring reaction 30-40 minute, then polyisobutene, biscyclo pentadienyl iron, cobalt naphthenate is added, stirring reaction 20-40 minute and get final product.
The preparation method of described paper-plastic package heat-seal adhesive, is characterized in that comprising the following steps:
Tributyl citrate, phenyl-trichloro-silicane, MALEIC ANHYDRIDE, propylene glycol, titanate coupling agent TMC-TTS are joined in N-BUTYL ACETATE, add cyclohexanone peroxide, stirring reaction 1-3 hour, continue to be heated to 80-90 DEG C, add 2-amino-2-methyl-1-propanol, tackifying assistant, stirring reaction 1-2 hour, then add other surplus stock, stirring reaction 2-3 hour and get final product.
It is reasonable that the present invention packs hot glue formula, and bonding strength is high, color inhibition, water-fast.
Embodiment
A kind of paper-plastic package heat-seal adhesive, be made up of the raw material of following weight part (kilogram):
E-12 epoxy resin 14, terpine resin 8, EVA resin 17, ethyl acetate 13, N-BUTYL ACETATE 23, tributyl citrate 4, phenyl-trichloro-silicane 4, MALEIC ANHYDRIDE 9, propylene glycol 6, titanate coupling agent TMC-TTS2, cyclohexanone peroxide 2,2-amino-2-methyl-1-propanol 9, vinyl triamine 4, tackifying assistant 5.
Described tackifying assistant is obtained by the raw material of following weight part (kilogram):
Thermoplastic acrylic resin 4, Silane coupling agent KH550 2,582-2 aminoresin 4, polyisobutene 3, N-BUTYL ACETATE 8, cobalt naphthenate 0.2, biscyclo pentadienyl iron 0.6;
Preparation method is: join in N-BUTYL ACETATE by thermoplastic acrylic resin, 582-2 aminoresin, so enter to add Silane coupling agent KH550, be heated to 90-100 DEG C, stirring reaction 30-40 minute, then polyisobutene, biscyclo pentadienyl iron, cobalt naphthenate is added, stirring reaction 20-40 minute and get final product.
The preparation method of paper-plastic package heat-seal adhesive, comprises the following steps:
Tributyl citrate, phenyl-trichloro-silicane, MALEIC ANHYDRIDE, propylene glycol, titanate coupling agent TMC-TTS are joined in N-BUTYL ACETATE, add cyclohexanone peroxide, stirring reaction 1-3 hour, continue to be heated to 80-90 DEG C, add 2-amino-2-methyl-1-propanol, tackifying assistant, stirring reaction 1-2 hour, then add other surplus stock, stirring reaction 2-3 hour and get final product.
The present invention is used for the bonding of paper and plastics film, after 5 hours, adhesive shear strength reaches 12Mpa.
