Abstract
The invention relates to a photocurable coating allowing repeated coating, which includes the following components, by weight, 40-45% of polyester acrylic resin, 10-15% of TM resin, 6-13% of a photo-initiator, 10-15% of epoxy resin, 0.5-1.5% of an additive and the balanced being a solvent which is prepared by mixing butyl propionate and ethyl ester according to the weight ratio of 1:1. The photo-initiator is an ultraviolet absorber. The additive includes one or more selected form a drier, a toughening agent, a defoamer, a flatting agent, an adhesion promoter, a dispersing agent and a photo-initiation accelerating agent. The photocurable coating allowing repeated coating is subjected to effective adjustment on internal chemical structure and internal molecular structure, is 15000-30000 in molecular weight, can avoid the problem of paint striping, hidden crack and the like in a modified resin coating in the prior art, is improved in adhesion force after second coating, can repair the hidden crack problem through increase of molecular density and is suitable for repeated coating.
Description
Technical field
The present invention relates to a kind of photo-cured coating, specifically a kind of based on the photo-cured coating of polyester acrylate resin, epoxy resin.
Background technology
Photo-cured coating is various in style, and major part is used for light industry product external decoration and covers with paint, lacquer, colour wash, etc., as products such as televisor, refrigerator, washing machine, power trucks.And under power truck external ornament is easy to be exposed to sunlight, thus need to consider the sticking power of coating and decoration, the problem such as depainting and moire spot in thermo-optical.
The technology of the present invention solves Problems existing, adopt new technology and newly fill a prescription, effectively adjust at coating internal chemical structure, molecular structure especially, change the phenomenon such as depainting, dark moire that modified resin coating in the past exists, coating is improved in secondary coating postadhesion power, molecular density improves has repaired dark moire phenomenon, is thus suitable for repeating to cover with paint, lacquer, colour wash, etc.
Summary of the invention
Technical problem to be solved by this invention is to provide the photo-cured coating of good the repeated covering with paint of a kind of sticking power.
For solving the problems of the technologies described above, the invention provides a kind of repeat cover with paint, lacquer, colour wash, etc. photo-cured coating, its component and weight percent as follows: polyester acrylate resin 40-45%, TM resin 10-15%, light trigger 6-13%, epoxy resin 10-15%, auxiliary agent 0.5-1.5%, balance of solvent.
Described solvent be with the third butyl ester, ethyl ester by weight ratio 1:1 mix.
Described light trigger is ultraviolet absorbers.
Described auxiliary agent comprises siccative, toughner, defoamer, flow agent, adhesion promoter, dispersion agent, light draw one or more that inspire agent etc.
The above-mentioned preparation method repeating the photo-cured coating covered with paint, lacquer, colour wash, etc. comprises the steps:
(1) the 1:1 mixing by weight ratio of the third butyl ester, ethyl ester is made into solvent a;
(2) by TM resin and appropriate solvent a mix and blend spanning tree lipoprotein solution b;
(3) by polyester acrylate resin and appropriate solvent a mix and blend spanning tree lipoprotein solution c;
(4) by proportioning by epoxy resin and appropriate solvent a mix and blend spanning tree lipoprotein solution d;
(5) by resin solution b, resin solution c and resin solution d mix and blend, then adopt spray method to add light trigger, auxiliary agent successively, add while stirring, after adding, stir the photo-cured coating namely configuring for 3-5 minute and form this and can repeat to cover with paint, lacquer, colour wash, etc.
Technique effect of the present invention: (1) photo-cured coating repeating to cover with paint, lacquer, colour wash, etc. of the present invention has carried out effective adjustment to coating internal chemical structure, molecular structure, the molecule content of coating is between 15000-30000, the depainting that modified resin coating of changing over exists, dark moire, phenomenon, coating is improved in secondary coating postadhesion power, molecular density improves has repaired dark moire phenomenon, thus can be suitable for repeating to cover with paint, lacquer, colour wash, etc.; (2) coating application of the present invention is convenient, and disposable covering with paint qualification rate is high, and not by process technology limit during construction, occurring that defect ware can be polished can spray again, and the cost that thus feeds intake is low, can enterprise benefit.
