Abstract

The invention discloses a novel environment-friendly flame-retardant wood-plastic composite which comprises the following raw materials in parts by weight: 44-78 parts of poplar wood powder, 33-48 parts of sorghum stalk powder, 12-14 parts of watermelon vine powder, 10-13 parts of woven bag plastic particles, 6-8 parts of a filler, 4-6 parts of composition, 1-2 parts of a lubricant, 1-2 parts of an anti-fungus and anti-mildew agent, 1-2 parts of a moisture absorbent, 2-4 parts of a flame retardant, 2-4 parts of a smoke inhibitor, 6-10 parts of an adhesive, 2-4 parts of a tackifier , 1-3 parts of a softener, and 1-2 parts of an ultraviolet light absorber. The novel environment-friendly flame-retardant wood-plastic composite can be widely applied to hotel, restaurant and building decoration, is good in flame-retardant effect, cannot be burnt or form flame, and is stable and reliable in performance.

Description

【Technical field】 [0001] The invention belongs to the field of wood-plastic material preparation technology and environmental protection, and specifically relates to a novel environmentally friendly flame-retardant wood-plastic material. 【Background technique】 [0002] Wood-plastic composite (WPC) is a composite material mainly made of wood or cellulose as the base material and plastic. It is a certain proportion of wood fibers (such as wood powder, straw powder, cotton stalk powder, bamboo powder, Nut shell powder, etc.) is a new type of material combined with thermoplastic polymer resin or other materials after pretreatment; Both raw wood fiber and polyolefin are flammable materials, so the composite material is also a flammable material. It is the need for the application and development of the material to endow the wood-plastic composite material with good flame retardancy; the flame retardancy of wood and wood fiber alone There are many studies, generally phosphorus-ni...
