Sulfonyl biochar flame-retardant wood-plastic plate and production method thereof

Abstract

The invention relates to the technical field of wood-plastic plates, in particular to a sulfonyl biochar flame-retardant wood-plastic plate and a production method thereof, and the sulfonyl biochar flame-retardant wood-plastic plate comprises the following components in parts by weight: 20-30 parts of bamboo and wood fiber powder, 90-110 parts of ground calcium carbonate, 70-90 parts of polyvinyl chloride resin powder, 9-15 parts of PBS resin, 8-12 parts of hollow ceramic micro-beads, 8-12 parts of an ethylene-vinyl acetate copolymer, 5.5-7.5 parts of sulfonated carbon, 4-5 parts of a heat stabilizer, 5-6 parts of a foaming regulator, 0.6-1.2 parts of a foaming agent, 0.5-1 part of stearic acid and 0.5-1 part of PE wax. The flame-retardant effect of the wood-plastic plate can be improved, and the release speed and release amount of smoke during combustion of the wood-plastic plate are reduced.

Description

technical field [0001] The invention relates to the technical field of wood-plastic panels, in particular to a sulfonic acid-based biochar flame-retardant wood-plastic panel and a production method thereof. Background technique [0002] With the development of the economy and the progress of the society, people's quality of life continues to improve, the demand for wood and other forest products is increasing day by day, and the difficulty of international import of forest products is increasing, so the contradiction between wood supply and demand continues to increase. In view of the current situation of supply and demand, scholars at home and abroad have conducted in-depth research to solve the contradiction between supply and demand of wood: first, make full and efficient use of existing wood resources and improve the utilization rate of wood; second, look for alternative products of wood products to reduce wood consumption. [0003] Wood-plastic composite (WPC) is a new ...

AI Technical Summary

Problems solved by technology

[0004] The existing wood-plastic composite materials do not have a long service life, and the high-temperature resistance is not ideal, so it is difficult to achieve the effect of flame retardancy when used in wood-plastic panels. Not only that, because ordinary wood-plastic panels will quickly release More smoke, which leads to a large amount of smoke and poisonous gas in the fire, which becomes the main cause of casualties and hinders fire rescue
