Abstract

The invention discloses a polyacrylate polymer composite material, which is characterized in that, in parts by weight, it comprises the following components: 100 parts of polyacrylate polymer; 15-100 parts of toughening agent; The toughening agent is selected from the compounding of a two-layer core-shell structure toughening agent and a three-layer core-shell structure toughening agent, and the two-layer core-shell structure toughening agent accounts for 10-45% of the total weight of the toughening agent. The above-mentioned polyacrylate polymer composite material has high transparency and high toughening efficiency, and the prepared film can be folded repeatedly in half without breaking or whitening marks.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyacrylate polymer composite material and a preparation method thereof. Background technique [0002] In recent years, PVC decorative materials have been widely used in interior architectural decoration, replacing traditional ceramics, paint, and wood decoration. PVC decorative materials are mainly films made of various patterns, which are glued to walls, furniture and other surfaces to achieve decorative and aesthetic effects. However, when used indoors for a long time, discoloration will occur in places exposed to sunlight such as windows, balconies, and doorways, and the surface is easily scratched, which affects the appearance. In outdoor walls, garden landscapes, etc., PVC decorative film also has a very large application demand. However, PVC itself has very poor weather resistance, and it is easy to change color when used outdoors, which limits its applicati...
