Abstract

The invention relates to a B-P-Zn-Si series density board flame-retardant mildew-proof agent and a preparation method and application thereof. The density board flame-retardant mildew-proof agent comprises the following raw materials in parts by mass: 30-90 parts of sodium borate, 30-70 parts of ammonium polyphosphate, 20-60 parts of zinc borate and 6-20 parts of organic silicon quaternary ammonium salt. The additive amount of the B-P-Zn-Si series density board flame-retardant mildew-proof agent provided by the invention is 4-6% of the absolute dry wood mass of raw materials of a density board when the B-P-Zn-Si series density board flame-retardant mildew-proof agent is applied. The flame-retardant mildew-proof density board manufactured by using the flame-retardant mildew-proof agent provided by the invention has the advantages of even oxygen index for combustion which exceeds 39.0%, capability of reaching the B1-level standard for the combustibility of construction and decoration materials and according with the requirements of the fire law.

Description

technical field [0001] The invention relates to a flame-retardant and mildew-proof material for density boards, in particular to a flame-retardant and mildew-proof agent for density boards containing B-P-Zn-Si elements and a method for using the same, 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 is seriously insufficient, w...
