Abstract

The invention relates to a plastic-wood composite photo frame. A frame strip is prepared from the following raw materials in parts by mass: 100 parts of polyvinyl chloride plastic particles, 45 parts of wood flour, 24-30 parts of attapulgite clay with an average particle size of 30-50 microns, 1-1.2 parts of a mesoporous molecular sieve, 5-8 parts of chlorinated polyethylene, 1-2 parts of a foaming agent, 1.8-2 parts of a lead salt heat stabilizer, 3.2-4 parts of a metallic soap heat stabilizer and 1.2 parts of an epoxy plasticizer. The invention further discloses a preparation method of the plastic-wood composite photo frame. According to the prepared plastic-wood composite photo frame, the frame strip is low in density, small in brittleness, large in hardness, high in strength and excellent in impact resistance; compared with an existing photo frame, the plastic-wood composite photo frame has great market competitiveness; and in addition, the preparation method is simple, the process is easy to control, production cost is low, and production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of plastic-wood composite photo frames, and in particular relates to a plastic-wood composite photo frame and a preparation method thereof. Background technique [0002] The emergence of wood-plastic composite materials can not only take advantage of the advantages of each component in the material, overcome the use limitations caused by low wood strength, large variability, and low elastic modulus of organic materials, but also make full use of waste wood and plastics. ,reduce environmental pollution. From the point of view of production raw materials, various waste plastics, waste wood and crop residues can be used as raw materials for wood-plastic composite materials. Therefore, the development and wide application of plastic-wood composite materials will help to slow down the pollution of plastic waste, and also help to reduce the environmental pollution caused by the incineration of agricultural waste....
