Abstract

The invention belongs to the technical field of fiberboard materials, particularly relates to a high-density fiberboard with an antibacterial function and a manufacturing process of the high-density fiberboard, and solves the problems that in the prior art, the antibacterial effect of a high-density fiberboard is poor and not lasting. The high-density fiberboard with an antibacterial function comprises the following raw materials in parts by weight: 30-50 parts of wood chips, 30-50 parts of straws, 15-25 parts of a polyethylene-maleic anhydride copolymer, 10-20 parts of poly (p-phenylene benzobisoxazole) fibers, 4-10 parts of solid paraffin, 3-5 parts of an adhesive, 3-7 parts of an antibacterial agent, 1-3 parts of carboxymethylcellulose and 2-5 parts of methyl tetrahydrophthalic anhydride. The high-density fiberboard with the antibacterial function is scientific in formula, rigorous in proportion, simple in preparation process and mild in preparation condition, and the obtained high-density fiberboard with the antibacterial function has excellent antibacterial performance and mechanical performance, almost does not release formaldehyde in the using process, is safe and environmentally-friendly and can be widely applied.

Description

technical field [0001] The invention relates to the technical field of fiberboard materials, in particular to a high-density fiberboard with antibacterial function and a manufacturing process thereof. Background technique [0002] In recent years, with the rapid development of the construction industry, wooden flooring has gradually become one of the important materials for interior decoration due to its natural environmental protection and superior texture. As an important product in wood flooring, laminate flooring is favored by the market because of its wear resistance, aesthetics and good stability. At present, the reinforced composite floor mainly uses medium and high-density fiberboard as the base material, and the high-density fiberboard is made of wood fiber or straw fiber and adhesive. Adhesives are mainly urea-formaldehyde resins, phenolic resins, etc., and auxiliary materials are generally insect repellents of chemically synthesized materials. The high-density b...
