Abstract

Relating to an all plastic wood-like material and its preparation method, the invention provides a flame retardant micro-foamed all plastic wood-like material and its preparation method. The all plastic wood-like material comprises: 100 of polystyrene, 20-40 of high impact polystyrene, 10-15 of resin, 2-5 of an inorganic filling material, 15-25 of fire retardants, 5-15 of a smoke suppressant, 0.5-1.5 of foaming agents, 0.5-2 of a cell regulator, 0.5-2 of a colouring agent and 1.5-3 of auxiliary agents. The method consists of: mixing the auxiliary agents, the colouring agent, the fire retardants, the smoke suppressant, the foaming agents and the cell regulator according to the ratio so as to obtain a mixture A; drying the resin and the inorganic filling material; mixing polystyrene, high impact polystyrene, resin and the inorganic filling material, as well as the mixture A, thus obtaining a mixture B; subjecting the mixture B to granulation, and molding the obtained particles, thus obtaining the halogen-free and flame retardant micro-foamed all plastic wood-like material.

Description

technical field [0001] The invention relates to an all-plastic imitation wood material and a preparation method thereof, in particular to a micro-foaming all-plastic imitation wood material with a flame-retardant function and a preparation method thereof. Background technique [0002] Micro-foamed all-plastic wood-like material is a new type of energy-saving and environmentally friendly wood replacement product. It is made of pure polymer material foam and can be 100% recycled and reused. Since wood, plastic-wood composite materials and all-plastic imitation wood materials are combustible substances, once burned, the fire will spread rapidly and form a fire, which will inevitably cause irreparable casualties and property losses. As a new type of wood-replacing product, all-plastic imitation wood material has been widely valued by industries such as construction and home decoration for its flame retardant performance. Wang Mei et al. (Research Progress on Flame Retardancy of...
