Problems solved by technology

[0002] PU rubber paint has been widely used, but its process is complicated, time-consuming, and drier must be added. This kind of catalyst contains organotin, a banned substance. People want to develop UV elastic handle paint with PU rubber feel, which is comparable to ordinary UV Compared with UV elastic touch paint, it has a super thick feeling and soft elasticity, but because the performance of the paint film is inversely proportional to the soft elasticity of the paint film, the two can be successfully developed only when they reach a balance.

Abstract

The invention relates to UV solidified elastic hand feeling paint and a production method. The method is characterized by including the following steps of firstly, sequentially throwing part of methyl isobutyl ketone, photoinitiator and light stabilizer in a small reaction still under a shielding condition, and conducting stirring till the solution is clear; secondly, sequentially throwing long-chain urethane acrylate, reactive monomer and branched polyester resin in a large reaction still, and conducting stirring; thirdly, adding matte agent into the large reactions till while stirring, and conducting stirring; fourthly, adding the mixture in the small reaction still into the large reaction still, adding the rest of methyl isobutyl ketone, and conducting stirring to obtain a component A; fifthly, throwing isobutanol, butyl cellosolve, ethyl acetate, 3-methyl-3-ethyl methoxyacetate, butanone and methyl isobutyl ketone in the large reaction still, and conducting stirring to obtain a component B; sixthly, packaging the component A and the component B independently, and mixing the component A and the component B for use in the use process. The hand feeling and performance of PU elastic paint can be achieved, and meanwhile no organic tin or other harmful substances are contained.

Description

technical field [0001] The invention relates to a UV curable elastic feel paint and a production method, in particular to a UV elastic feel paint used in the field of 3C electronic consumer goods, belonging to the technical field of coatings. Background technique [0002] PU rubber paint has been widely used, but its process is complicated, time-consuming, and drier must be added. This kind of catalyst contains organotin, a banned substance. People want to develop UV elastic handle paint with PU rubber feel, which is comparable to ordinary UV Compared with UV elastic touch paint, it has super thick feeling and soft elasticity, but because the performance of the paint film is inversely proportional to the soft elasticity of the paint film, it can only be successfully developed when the two reach a balance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a UV curing elastic feel paint and pr...
