Problems solved by technology

However, UV-curable coatings often affect the quality of the paint film due to the residual release agent on the surface of the BMC, and the paint film is prone to shrinkage and other undesirable phenomena.
Generally, polyether-modified polysiloxane leveling agents are added to UV-cured coatings to improve the shrinkage problem of the paint film, but after the paint film is cured, the polyether-modified polysiloxane leveling agent used will migrate to The surface of the paint film, thus affecting the adhesion of aluminum plating
However, if the polyether modified silicone leveling agent is not used, the effect of reducing surface tension and improving shrinkage cavity cannot be achieved

Abstract

The invention discloses a reactive coating and ink auxiliary agent, which is mainly synthesized from a fluorine-containing acrylate monomer, a double bond-containing organic silicon monomer, an initiator, a chain transfer agent, and a solvent through a radical solution copolymerization process. The product of the present invention can not only effectively reduce the surface tension of the UV-curable coating and prevent the shrinkage cavity of the paint film, but also participate in the cross-linking reaction of the UV-curable coating to prevent it from migrating to the surface of the coating film, so as not to affect the vacuum aluminum plating of adhesion.

Description

Technical field [0001] The invention relates to a method for synthesizing a reactive coating and ink auxiliary agent. Background technique [0002] Car lamp reflectors are made of BMC (bulk molding compound) through aluminizing process to meet the light distribution effect. Due to the defects on the BMC surface, the light distribution effect is poor after direct aluminum plating, and UV curing coatings are required before aluminum plating. However, UV-curable coatings often affect the quality of the paint film due to the residual release agent on the BMC surface, and the paint film is prone to shrinkage and other undesirable phenomena. Generally, polyether-modified polysiloxane leveling agent is added to UV-curable coatings to improve the shrinkage problem of the paint film, but after the paint film is light-cured, the polyether-modified polysiloxane leveling agent used will migrate to Paint film surface, thereby affecting the adhesion of aluminum plating. However, if the polye...
