Abstract

The invention relates to a B-P-Mg-Si series density fiber board inflaming-retarding mildewproof agent and a preparation method and application thereof. The density fiber board inflaming-retarding mildewproof agent comprises the raw materials in parts by weight: 30-100 parts of sodium borate, 20-90 parts of polyammonium phosphate, 40-60 parts of magnesium hydroxide and 6-20 parts of organosilicon quaternary ammonium salt. When used for preparing a density fiber board, the B-P-Mg-Si series density fiber board inflaming-retarding mildewproof agent has the addition amount of 4-6 percent of the mass of oven-dry wood as the density fiber board. An inflaming-retarding mildewproof density fiber board prepared by adopting the B-P-Mg-Si series density fiber board inflaming-retarding mildewproof agent has combustion oxygen indexes of exceeding 39.0 percent, can reach the B1-level standard of the combustion performance of building finishing materials, and accords with the requirement of fire service law.

Description

technical field [0001] The present invention relates to a density board flame-retardant anti-mildew material and its preparation method and application, in particular to a density board flame-retardant anti-mold agent containing B-P-Mg-Si element and its preparation method and application, belonging to chemical materials technology field. Background technique [0002] With the rapid development of the national economy, people's living standards have been greatly improved, and the per capita housing area is getting larger and larger. At present, the per capita housing construction area of ​​our residents has exceeded 30 square meters per person. The unprecedented prosperity of the interior decoration industry has led to a large consumption of various materials. In 2009, my country's timber consumption reached 330 million cubic meters, becoming the second largest timber consumer in the world after the United States. my country's forest resources are scarce, and the timber is...
