Abstract

The invention relates to an environment-friendly flame-retardant polyester wood-like material for a building material and a preparation method of the environment-friendly flame-retardant polyester wood-like material, belonging to the technical field of polyester modification. The environment-friendly flame-retardant polyester wood-like material for the building material is prepared from a component A and a component B, wherein the weight percentage ratio of the component A to the component B is 1:1.6; the component A is prepared from polyester polyol A, polyether polyol B, a foam stabilizer, a chemical foaming agent, a catalyst, a flame retardant and a physical foaming agent; the component B is multi-methyl multi-phenyl polyisocyanates or diphenylmethane diisocyanate. The environment-friendly flame-retardant polyester wood-like material for the building material, which is provided by the invention, not only has the characteristics of high flame retardancy, high pressure resistance, high tension strength and high bending strength, but also has the use characteristics of wooden materials. The invention further provides the preparation method of the environment-friendly flame-retardant polyester wood-like material for the building material. The environment-friendly flame-retardant polyester wood-like material is simple in preparing technology, low in cost and high in production efficiency.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant polyurethane imitation wood material for building materials and a preparation method thereof, belonging to the technical field of combined polyether. Background technique [0002] Due to the excessive exploitation of forest resources, the ecological environment has deteriorated and soil erosion has been caused. As an excellent substitute for wood, polyurethane imitation wood materials will surely become the mainstream of indoor and outdoor building decoration materials in today's extremely scarce wood resources in my country. [0003] When preparing polyurethane imitation wood on the market, the catalysts generally used in the combined polyether are PC8 (N, N-dimethylcyclohexylamine), Y-27 (N, N-dimethylbenzylamine), PC41 (1 ,3,5-tris(dimethylaminopropyl)-hexahydrotriazine), which is volatile and has a strong odor, and has a strong stimulating effect on the human respiratory tract, eyes, ...
