Abstract

The invention discloses acrylic primer base stock and acrylic primer as well as a preparation method and application of the acrylic primer. The acrylic primer base stock comprises the following components in percentage by weight: 75.0%-85.0% of special modified methacrylate, and 3.0%-10.0% of cellulose acetate butyrate liquor. The primer base stock is mainly used for a plastic enclosure and buttons of a mobile phone. The acrylic primer base stock satisfies the halogen-free paint requirements in the mobile phone industry. The acrylic primer produced by the acrylic primer base stock disclosed by the invention is matched with spraying ultraviolet-light radiation finish for use, and sprayed on polycarbonate plastic, so that the dried and cured coating has excellent boiling resistance.

Description

technical field [0001] The invention relates to the field of paint making, in particular to an acrylic primer base material, an acrylic primer and a preparation method and application thereof. Background technique [0002] With the improvement of human awareness of environmental protection, the requirements for coatings used on mobile phone casings and buttons are getting higher and higher. In addition to requiring no halogens and heavy metals, some companies now have high requirements for solvent systems in coatings. , requiring no benzene solvents. Due to the good solvency and price advantages of benzene solvents, most of the resins and additives used in the coating industry today contain benzene solvents. So far, no other companies have found primers that do not contain halogens and benzene solvents. After matching the UV-cured topcoat, it can pass the test of boiling at 100°C for 30 minutes. After the test, the coating film will not bubble, crack, or change color, and i...
