Abstract
The invention relates to modified unsaturated polyester resin and in particular relates to polishing-free highlight coating resin. The polishing-free highlight coating resin is characterized in that at least one air-dried monomer is introduced into unsaturated polyester and at least two photoinitiators, namely surface layer initiator photo-curing resin and deep layer initiator photo-curing resin respectively, are adopted. According to the polishing-free highlight coating resin, the air-dried monomer is introduced into the unsaturated polyester, multiple photoinitiators are adopted for playing a synergistic effect, and an ingenious formulation design is adopted, so as to obtain a polishing-free highlight coating, so that a polishing process is eliminated, the production efficiency is improved, the usage amount of resin is reduced, and the production cost is saved; furthermore emission of VOC (volatile organic compounds) is reduced while a photocuring process is adopted, thereby being consistent with the policy of building a resource-saving and environmentally-friendly society advocated in China.
Description
Technical field
The present invention relates to a kind of unsaturated polyester resin of modification, particularly a kind of high light coating resin of exempting to polish.
Background technology
Coating resin is widely used in the external coating of the woodworks such as piano, top-grade furniture, woodenware artwork or plasthetics, and its technique is simple, good by its product surface hardness and glossiness of doing, plays protection and decorative effect, thereby wide market is very arranged.
Do at present coating resin both at home and abroad and mainly contain three kinds of systems:
1, high bake coating resin, this resin system contains a large amount of solvents, and in atmosphere, to environment, although after solidifying, can obtain the not coating resin of sanding and polishing, hardness and fullness ratio effect are not very desirable through the overbaking solvent evaporates.
2, the unsaturated coating vibrin of ambient cure, the technique of employing is the ambient cure system, and the shortcoming of this technique is that (1) is slow set time, and a large amount of styrene solvent volatilizations are arranged in the process of solidifying, and not only efficiency is low, and to environment; (2) adopting unsaturated polyester resin to do coating needs sanding and polishing, not only wastes starting material, and complex process, affects production efficiency.
3, there are two problems one in the coating done of original light solidifying coating resin, there is no fullness ratio; Two, fullness ratio has been arranged but not anti-xanthochromia.
Although existing coating resin adopts not polishing, the polishing of PU system, it needs high bake, not only waste energy, and also the solvent contamination environment of volatilization, the coating fullness ratio obtained is not good, and hardness is also poor; Although adopting the PE system is ambient cure, polish, just can obtain after polishing the good and hardness of fullness ratio coating preferably, not only set time long, and complex process, so production efficiency is low; In addition, the coating resin that is used in now the woodenware ground is not anti-xanthochromia generally, anti-xanthochromia and there is no fullness ratio, and price is also somewhat expensive.
Summary of the invention
The objective of the invention is to solve the problem of environmental pollution that the PU coating resin brings and fullness ratio is not good, the problem of difference of hardness, reduce PE coating resin this operation of polishing, thereby enhance productivity, but also can be in the situation that the coating of not improving price and obtaining a not only anti-xanthochromia but also fullness ratio is arranged provides a kind of high light coating resin of exempting to polish.
The technical scheme that realizes the object of the invention is: a kind of high light coating resin of exempting to polish comprises unsaturated polyester; It is characterized in that: this resin, in unsaturated polyester, introducing at least a air-drying property monomer, adopts at least two kinds of light triggers, is respectively top layer initiator and deep layer initiator light-cured resin.
The above-mentioned high light coating resin of polishing of exempting from, described air-drying property monomer is preferably tetrahydrophthalic anhydride or dicyclopentadiene.
The above-mentioned high light coating resin of polishing of exempting from, the preferred add-on of described air-drying property monomer is the 15-20% of total mass.
The above-mentioned high light coating resin of polishing of exempting from, described top layer initiator is preferably α ￣ hydroxyl ketone class initiator, and the deep layer initiator is preferably acylphosphine oxide class initiator.
The above-mentioned high light coating resin of polishing of exempting from, preferably top layer initiator add-on is 3-5%, deep layer initiator add-on is 0.5-1%.
The above-mentioned high light coating resin of polishing of exempting from, concrete components based on weight percentage is:
A: modified unsaturated polyester resin component:
The total amount of above-mentioned each monomer is 100%;
The 30-50% of aforementioned each monomer total amount of diallyl ether;
B: the high light coating resin component of exempting to polish:
The above-mentioned high light coating resin of polishing of exempting from, the amount of described diallyl ether is preferably 42.9% of aforementioned each monomer total amount.
The above-mentioned high light coating resin of polishing of exempting from, described auxiliary agent is preferably flow agent and defoamer.
TPGDA of the present invention is tripropylene glycol diacrylate; HDDA is 1,6 hexanediol diacrylate; TMPTA is trishydroxymethyl three vinylformic acid propane esters.
The present invention carries out modification to original unsaturated polyester, makes coating in the situation that do not add wax liquid energy resistance to the oxygen inhibiting polymerization by introducing the air-drying property monomer, reduces this operation of coating polishing, and this not only increases work efficiency, and reduces the waste of coating resin.
The present invention changes the technique of original ambient cure, in original unsaturated polyester, add the auxiliary agents such as light trigger, adopt the technique of photocuring that coating is solidified at short notice, solve the phenomenon of oxygen inhibition, thereby obtain the coating of a high gloss, high rigidity, so not only reduce the discharge of VOC, and can reach the not purpose of polishing.
The main body principle of this programme: adopt different light triggers, first use top layer light trigger (for example vapour bar 184,1173) that coatingsurface is first solidified, purpose is to avoid airborne oxygen to produce inhibition to coating curing, thereby affect hardness and the gloss of coating, then select deep layer light trigger (for example TPO) to make coating under top layer admittedly carry out deep layer and solidify, thereby obtain a complete coating.
The present invention has positive effect: (1) is by introducing the air-drying property monomer in unsaturated polyester, and adopt multiple light trigger photocuring performance to act synergistically, and has exquisite formulating of recipe, obtain a high light coating of exempting to polish, reduce the polishing operation, enhance productivity, and reduce resin demand, save production cost; While (2) adopting ultraviolet curing process, reduce the discharge of VOC, meet country and advocate the policy of building a resource-conserving and environment-friendly society.
