Abstract

The invention belongs to surface protection technology, and relates to an acrylic paint and a preparation method thereof. The preparation method of acrylate paint of the present invention, will adopt two kinds of monomers of methyl methacrylate and butyl methacrylate of specific proportioning under heating and the cross-linking promotion of dibenzoyl peroxide, the activity of two kinds of monomers The functional group undergoes a cross-linking and curing reaction to form an acrylate coating with a bulky polymer structure. The preparation method of the present invention has strong operability, simple process, easy control, clear and transparent appearance of the product, beautiful coating formed after coating, significantly enhanced abrasion resistance, chemical resistance and adhesion compared with conventional thermoplastic acrylic coatings, and Good water resistance, not easy to be corroded by moisture.

Description

technical field [0001] The invention belongs to surface protection technology, and relates to an acrylic paint and a preparation method thereof. Background technique [0002] Currently, thermoplastic acrylic coatings are commonly used for coating aviation products. This coating is a polymer with a linear structure, does not contain active functional groups, and will not cross-link itself or with other external resins to form a bulky structure. The coating is easy to soften when heated, and can return to its original shape after cooling, but its wear resistance and chemical resistance are not good enough to meet the coating requirements of modern aviation products. Contents of the invention [0003] Purpose of the invention: In order to overcome the shortcomings of thermoplastic acrylate coatings, an acrylic coating with good abrasion resistance, chemical resistance, water resistance and adhesion and its preparation method are provided. [0004] The technical scheme of the...
