Abstract

The invention discloses an amphiphilic modified acrylate copolymer binder and a preparation method thereof. The invention belongs to the technical field of materials, aims at providing a binder, and particularly provides an amphiphilic oligomer block-modified acrylate copolymer binder and a preparation method thereof. With the rapid development of the economy, a binding technology is more widely applied. In order to obtain efficient and environment-friendly products, higher and higher requirements for the comprehensive performance of the binder are put forward. In various polymer materials, acrylic polymers are widely applied due to the advantages of excellent weather resistance, oil resistance, oxygen (ozone) resistance and adhesive force, as well as numerous monomers, and are easy synthesis, low price and the like. According to the invention, a high-performance binder is prepared by a self-made amphiphilic oligomer modified acrylate copolymer, and the binder has strong adhesive force, stable performance, good water resistance and heat resistance, and good oil surface binding performance.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to an adhesive, in particular to an amphiphilic oligomer block-modified acrylate copolymer adhesive and a preparation method thereof. Background technique [0002] Copolymers are a class of materials with unique structures and properties, and can be regarded as hybrid products of different homopolymers. Copolymer properties such as thermal properties, dielectric properties, and solubility can be controlled through its composition. One of the uses of copolymers is as a solubilizer for blending immiscible polymers. Copolymers and structure and sequence distribution are important parameters affecting solubility and, in turn, the ability of one copolymer to be miscible with another. Compared with random copolymers, block and multi-block copolymers can be used as better interfacial modifiers in two-phase polymer blends. [0003] Block copolymers are attracting widespread interest du...
