Thermoplastic composite material and preparation method thereof

Abstract

The invention relates to a thermoplastic composite material and a preparation method thereof. The thermoplastic composite material is composed of the following components in parts by weight: 35 to 55 parts of calcium carbonate powder, 5 to 8 parts of wood chip, 3 to 6 parts of bamboo chip, 8 to 10 parts of wheat straw, 5 to 8 parts of rice husk, 0.5 to 1 part of nickel sulfate hexahydrate, 5 to 8 parts of sodium hydroxide solution (2-3%), 6 to 8 parts of polyoxyethylene ether sodium dodecanol sulfate, 5 to 8 parts of crosslinked polyvinyl pyrrolidone, 3 to 6 parts of tridecafluorooctyl triethoxysilane, 3 to 5 parts of bleaching powder, 0.2 to 0.6 part of sodium thiosulfate, 3 to 8 parts of PP toughening agent, and a proper amount of pigment. The composite material is waterproof and mold-resistant, and enhances the elasticity and plasticity of wall. After construction, a uniform and beautiful effect is achieved, and the brightness is obviously increased. The raw materials are wastes, the price is low, wastes are reutilized, the environment is protected, and the economic benefit is prominent.

Description

technical field [0001] The invention relates to a thermoplastic composite material and a preparation method thereof. Background technique [0002] At present, expensive organic coating materials such as polyvinyl alcohol, titanium dioxide, and lithopone are commonly used in interior wall coatings for general buildings in China, which are easy to fall off, are not washable and moisture-proof, and are likely to cause secondary pollution. In addition, the mortar of lime powder and lime paste has low viscosity, low hardness and wall crack resistance, high cement consumption, and poor moisture-proof and air-permeable properties. Since the mid-1980s, there has been great interest in the manufacture of thermoplastic composites using the pultrusion process. This is because the use of thermoplastic composite materials can avoid the inherent disadvantages of thermosetting composite materials such as poor environmental friendliness, long processing cycle and difficulty in recycling, a...
