Abstract

The invention relates to a 3C paint, particularly a high-solid low-VOC (volatile organic compound) benzene-free solvent-type acrylic resin. The high-solid low-VOC (volatile organic compound) benzene-free solvent-type acrylic resin is a benzene-free system and is composed of a component A, a component B and a component C. The component A is composed of butyl acetate and propylene glycol methyl ether acetate. The component B is composed of methyl methacrylate, styrene, 2-hydroxypropyl acrylate, butyl methacrylate, butyl acrylate, acrylic acid and tert-butyl peroxybenzoate. The component C is composed of tert-butyl peroxybenzoate and butyl acetate. When being used as a finish paint matched with the primer for 3C electronic products, the resin has the advantages of favorable matching property, higher hardness, higher wear resistance, excellent alcohol resistance, excellent chemical resistance, excellent artificial sweat resistance, excellent cold / heat shock resistance, excellent high-temperature / high-dampness resistance, excellent artificial aging resistance and the like. The resin has high solid content, low viscosity and lower VOC, is more environment-friendly when being used as a benzene-free system, and has higher market competitiveness.

Description

technical field [0001] The invention relates to a 3C paint, in particular to a high-solid, low-VOC benzene-free solvent-based acrylic resin. Background technique [0002] 3C coating is the general term for coatings used in 3C products, and the so-called "3C products" are the combination of computers (Computer), communications (Communication) and consumer electronics (Consumer Electronics), also known as "information appliances". In 2014, the fourth year of the "Twelfth Five-Year Plan", China's transformation from "world factory" to "world market" has begun to emerge, and China's 3C industry will also face a new opportunity for comprehensive development. During the "Twelfth Five-Year Plan" period, the scale of my country's communication investment will reach 2 trillion yuan, and the 3C industry is facing a rare opportunity for development. At present, the large market of the 3C industry has indeed become one of the driving forces for the development of the national economy, ...
