Abstract

The invention discloses an environment-friendly flame-retardant straw board for a building. The environment-friendly flame-retardant straw board comprises the following components in parts by weight:20-35 parts of straw; 10-16 parts of nano WEP high-fiber resin powder; 5-12 parts of carbon fiber resin composite material powder; 8-14 parts of sisal hemp; 6-10 parts of flame-retardant fibers; 3-5 parts of an environment-friendly bactericide; 2-3 parts of an adhesive; 1-2 parts of a waterproof agent; and 1-3 parts of a flame-retardant agent, wherein the carbon fiber resin composite material powder comprises the following components in parts by weight: 35-40 parts of carbon fibers, 12-20 parts of epoxy resin, 20-32 parts of phenolic resin, and 6-13 parts of polytetrafluoroethylene, the environment-friendly bactericide is nano-silver, and the flame-retardant fibers are polybenzimidazole fibers. According to the invention, waste materials are reasonably utilized to prepare the board throughsimple processing procedures, so that not only are the resources saved and the cost reduced, but also the board has good glossiness and certain air purification capacity, and the board has the advantages of higher flame retardancy, high fatigue strength, high impact toughness, water resistance and antibacterial property, thereby prolonging the service life of the board.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly flame-retardant straw plate for building and a preparation method thereof. Background technique [0002] Environmentally friendly materials refer to low-toxic, low-emission decorative materials that have been processed and synthesized to control the accumulation and slow release of toxic and harmful substances, and because of their mild toxicity, they do not pose a danger to human health. Such as large-core boards, plywood, fiberboards, etc., which have low formaldehyde emission and meet national standards. Science and technology and testing methods cannot determine and evaluate the impact of toxic substances. The production process needs to consume a lot of materials. At present, such materials generally have problems such as non-environmental protection, cumbersome production and processing technology, and high cost. Contents of the inventio...
