[0006] At the same time, the performance of traditional wood-based panels in terms of mildew resistance and flame retardancy needs to be improved. When new wood-based panels replace anti-better panels and are used indoors or in environmental conditions that are prone to mildew, it is necessary to ensure product quality and improve its resistance. Bacteria and mildew resistance and flame retardant properties

Abstract
The invention discloses a composite auxiliary agent for a compact grade laminate. The composite auxiliary agent comprises the following components: a heavy calciumcarbonate dispersing agent, a mouldinhibitor and a flame retardant, wherein the heavy calciumcarbonate dispersing agent comprises water, acrylic ester, polyacrylamide, benzyltrimethylammonium chloride, sodium dodecyl sulfonate and polyethylene glycol. The composite auxiliary agent provided by the invention can reduce dispersion costs and promote curing of an adhesive while ensuring effective dispersion of heavy calciumcarbonatepowder in the process of manufacturing the laminate; and further, when the auxiliary agent provided by the invention is adopted for dispersion, an original artificial board technological process is notchanged, industrialized implementation is facilitated, and the dispersion method has low requirements for equipment, and is beneficial to reducing equipment investment of a production enterprise.
Description
technical field [0001] The invention relates to a compounding auxiliary agent and its use, in particular to a compounding auxiliary agent for anti-folding boards and its use. Background technique [0002] Since entering the 21st century, my country's wood-based panel industry has maintained a momentum of rapid development, and the output of wood-based panels has leapt to the first place in the world. However, the contradiction between wood-based panel production, raw material supply, and performance improvement is becoming increasingly acute. Therefore, it is urgent to develop new raw materials to replace wood to solve the problem of insufficient supply of raw materials. At the same time, it is also necessary to find new composite and functional wood-based panels to replace the traditional "three Large boards" (plywood, particle board, fiberboard). Among them, anti-fold special board is a kind of high-performance board made of natural fiber materials such as kraft paper as ...
