Abstract

The invention relates to a halogen-free inflaming retarding type micro-foaming full-plastic wood-simulating material and a preparation method thereof and relates to a micro-foaming full-plastic wood-simulating material. The full-plastic wood-simulating material comprises the following components in mass ratio: 100 of polystyrene, 20-40 of high impact polystyrene, 10-15 of resin, 2-5 of inorganic filling material, 30-60 of halogen-free inflaming retarding agent, 10-20 of smoke inhibiting agent, 0.5-1.5 of foaming agent, 0.5-2 of cell regulating agent, 0.5-2 of coloring agent and 1.5-3 of auxiliaries. The preparation method comprises the following steps: mixing the auxiliaries, the coloring agent, the halogen-free inflaming retarding agent, the smoke inhibiting agent, the foaming agent and the cell regulating agent in the component proportion so as to obtain a mixed material A; drying the resin and the inorganic filling material and mixing polystyrene, high impact polystyrene, the resin, the inorganic filling material and the mixed material A, so as to obtain a mixed material B; and granulating the mixed material B, and shaping the obtained particle material, so as to obtain the halogen-free inflaming retarding type micro-foaming full-plastic wood-simulating material.

Description

technical field [0001] The invention relates to a micro-foaming all-plastic imitation wood material, in particular to a halogen-free flame-retardant micro-foaming all-plastic wood-imitation material and a preparation method thereof. Background technique [0002] Wood, wood-plastic composite materials and all-plastic wood-like materials are combustible substances and are easy to burn. However, most of their application fields, such as outdoor construction and interior decoration, have flame retardant requirements. One of the new directions of technology development in the imitation wood material industry is to develop a halogen-free flame-retardant micro-foam imitation wood material with good flame retardancy. Traditional halogen-containing flame retardants have good flame retardant properties and have been widely used in wood and plastic preparation industries. Wu Yaozu (Patent Publication No. CN1382583) discloses a wood-like flame-retardant decorative panel and its product...
