Problems solved by technology

[0003] The embodiment of the present invention provides a film-forming compound for a seamless laser transfer coating and a preparation method thereof, which can solve the problems of black plate and low saturation of the molded pattern when using traditional film-forming materials for molding. The problem is that when using the film-forming composition for molding, it will not produce a black plate even if it works continuously at high temperature for a long time, and the saturation of the molded pattern is high

[0021] The preparation method of the film-forming composition of the above-mentioned seamless laser transfer coating comprises the following steps:

[0022] Get each component according to the prescription of film-forming composition;

[0023] Add the organic solvent into the reaction kettle, mix and heat to 50°C with stirring at a stirring rate of 15-30Hz;

[0024] Then put the polyacrylate polymer into the reaction kettle and stir for 2 to 3 hours at a stirring rate of 35 to 50 Hz;

[0025] Then put the epoxy resin into the reaction kettle, and stir for 0.5 to 1 hour at a stirring rate of 15 to 30 Hz;

[0026] After stirring, the temperature is lowered to 20-25°C, the latent curing agent and additives are sequentially added into the reaction kettle, and the composition obtained by stirring at a stirring rate of 15-30Hz for 2-2.5 hours and filtering out is the seamless plate Film-forming composition for laser transfer coating.

Abstract

The invention discloses a film-forming composition of a seamless laser transfer coating and a preparation method thereof. In the film-forming composition, a polyacrylate polymer and epoxy resin are used as basic film-forming substances, ester, ketone, ether and alcohol organic solvents are used as solvents, and the epoxy resin is crosslinked and solidified through a latent solidifying agent in the film-forming process so as to improve the hardness and temperature resistance of the system polymer, thereby meeting the requirement of the current seamless double-mould pressing process. After film formation, the film-forming composition has high brightness and excellent laser pattern saturation degree.

Description

technical field [0001] The invention relates to the field of coating film formation, in particular to a film-forming composition for forming a high-hardness seamless laser transfer coating and a preparation method thereof. Background technique [0002] In the field of laser transfer coating, especially in the field of seamless molding, at present, domestically, in terms of improving the temperature resistance of polyacrylate film-forming materials or cellulose ester film-forming materials, it mainly relies on adding a large amount of slip agent and leveling agent to improve polymerization. This technology can meet the current process requirements, and the highest molding temperature can reach 190°C. However, when molding at high temperature, small molecular weight additives are easy to precipitate on the surface of the polymer at higher temperatures, slow It sticks slowly to the surface of the laser plate, causing black spots, and the plate will be changed every 20,000 to 40...
