Abstract

The invention belongs to the technical field of fiberboard materials, particularly relates to a high-density fiberboard with high fire resistance and a preparation method of the high-density fiberboard. The problems that in the prior art, a fiberboard can release harmful substances such as formaldehyde, the fiberboard belongs to an inflammable material are solved, and the high-density fiberboard comprises the following raw materials of, in parts by weight, 30-50 parts of wood chips, 30-50 parts of straws, 10-20 parts of light silicon dioxide, 3-5 parts of an adhesive, 3-5 parts of a flame retardant, 1-3 parts of magnesium stearate, 2-4 parts of hexamethyldisiloxane and 2-5 parts of p-hydroxybenzenesulfonic acid. According to the high-density fiberboard with the high fire resistance and the preparation method of the high-density fiberboard, the high-density fiberboard is scientific in formula and rigorous in proportion, the obtained high-density fiberboard has excellent fire-resistant and flame-retardant performance, waterproof and moistureproof performance and physical and mechanical performance, the preparation method of the high-density fiberboard is simple, mild in preparation condition and easy for industrial production, 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 strong fire resistance and a preparation method 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 boar...
