Abstract

The invention relates to a B-P-Sb-Si series density fibre board inflaming-retarding mildewproof agent and a preparation method and application thereof. The density fibre board inflaming-retarding mildewproof agent comprises the raw materials in parts by mass: 40-100 parts of sodium borate, 30-80 parts of ammonium polyphosphate, 30-60 parts of antimonous oxide and 6-30 parts of organosilicon quaternary ammonium salt. When being applied, the B-P-Sb-Si series density fibre board inflaming-retarding mildewproof agent has the addition amount of 4-6 percent of mass of oven-dry wood as a density fiber board. An inflaming-retarding mildewproof density fiber board prepared by using the B-P-Sb-Si series density fibre board inflaming-retarding mildewproof agent has combustion oxygen indexes of exceeding 40.0 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 invention relates to a flame-retardant and mildew-proof material for density boards and its preparation method and application, in particular to a B-P-Sb-Si series density board flame-retardant and mildew-proof agent and its preparation and application, belonging to the technical field of chemical materials science. 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...
