Abstract

The invention discloses a preparation method of an inflaming-retarding wood-plastic composite material. The preparation method comprises the following steps of crushing zeolite powder, ferroferric oxide and talcum powder, adding novolac epoxy resin and microcrystalline cellulose, and uniformly mixing to obtain a first prefabricated material; uniformly mixing pollen pini polysaccharide, bentonite, melamine and acetone, heating, preserving heat, adding phthalimide and diallyl bisphenol A, uniformly agitating, ultrasonically treating, adding bismaleimide, agitating, filtering and drying to obtain a second prefabricated material; adding a lignin fiber and the second prefabricated material into the first prefabricated material, uniformly agitating, adding a titanate coupling agent and tricresyl phosphate, uniformly agitating, then placing in a mold to carry out hot press fit, and cooling to obtain the inflaming-retarding wood-plastic composite material.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a preparation method of flame-retardant wood-plastic composite materials. Background technique [0002] Wood-plastic composites contain plastic and fibers, so they have similar processing properties to wood, and their nail holding power is significantly better than other synthetic materials, and their mechanical properties are better than wood materials. Its nail holding power is generally 3 times that of wood and 5 times that of particleboard. Wood-plastic composites contain plastic, so they have a better modulus of elasticity. In addition, because it contains fibers and is fully mixed with plastic, it has physical and mechanical properties equivalent to hardwood such as compression and bending resistance, and its durability is significantly better than ordinary wood materials, and it can resist strong acid and alkali, water and corrosion. , and does n...
