Abstract
The invention belongs to the field of paints and specifically relates to an UV photosensitive paint. The UV photosensitive paint is characterized by comprising the following components of: by weight, 20-25 parts of a photosensitive resin of an epoxy resin and acrylic acid at the mol ratio of 1:1; 2-5 parts of a photosensitizer 1-hydroxycyclohexylphenylketone; auxiliary agents: 3-5 parts of an antifoaming agent; 3-5 parts of a thickening agent; 3-5 parts of a modifier; an active diluent: the balance being hexanediol. With benzophenone in the prior art replaced with the photosensitizer 1-hydroxycyclohexylphenylketone, the UV photosensitive paint has higher photosensitivity and requires less amount; in addition, during synthesis, the photosensitizer is simultaneously used as a catalyst for the synthesis of the photosensitive resin and therefore has a substantial application prospect in the industrial application.
Description
Technical field
The invention belongs to coating art field, be specifically related to a kind of UV photosensitive coating.
Background technology
Photoactive coating is compared with traditional coating, has pollution-free, simple, the characteristics such as cost is low, efficient height of use operation, is described as green coating.Photoactive coating mainly is made up of photosensitive prepolymer, reactive thinner, light initiation system three parts.Photosensitive prepolymer is the chief component of photoactive coating.Ultraviolet cured epoxy vinylformic acid photoactive coating is a kind of important new coating, can be widely used in the metal and the non-metallic coating material in fields such as machinery, electronics, photosensitive-ink.This material has the advantage that can be coated with heat sensitive base material, so be widely used in high-speed automated production line in recent years.Yet the UV-curing technology utility theory is also not overripened, needs better perfect.Through this use in several years, find that UV-curing technology has certain restriction to the curing depth of coating, the object shapes that requires to be cured is simple, regular, and it is printing opacity that the sizing agent performance of using simultaneously must have one side at least.These shortcomings of UV-curing technology have limited its deeper development to a certain extent.The application at first utilizes epoxy resin and vinylformic acid reaction to form photosensitive resin; Form photoactive coating to photosensitive resin and reactive thinner, photosensitizers reaction again; The coating that experiment confirm makes through this method has the good advantage of photosensitive property, and can be adapted to the demand of high-speed automated production line well.
Summary of the invention
The purpose of this invention is to provide a kind of UV photosensitive coating, overcome the difficult problem of prior art.
A kind of UV photosensitive coating, its characteristic is being made up of following composition by weight:
Photosensitive resin: epoxy resin and vinylformic acid mol ratio 1: 1,20-25 part altogether; Photosensitizers: 1-hydroxy-cyclohexyl phenyl ketone 2-5 part; Auxiliary agent: skimmer 3-5 part; Thickening material 3-5 part; Properties-correcting agent 3-5 part; Reactive thinner: surplus is a pinakon.
Its preparation method is: by the said ratio weighing, epoxy resin is placed 92-95 ℃ of environment, be added dropwise to photosensitizers and vinylformic acid under constantly stirring, behind the formation photosensitive resin, add reactive thinner and auxiliary agent, finished product.
Skimmer, thickening material, properties-correcting agent, the wide safe chemical industry of Yixing City ltd.
Beneficial effect
1, the present invention adopts photosensitizers 1-hydroxy-cyclohexyl phenyl ketone, replaces benzophenone of the prior art, and it is photosensitive higher; Consumption still less, simultaneously when synthetic, photosensitizers is simultaneously as the catalyzer that synthesizes photosensitive resin; Two get at one stroke, on industrial application, have significant application prospect
