Heat-preservation fireproof board and preparation method thereof

Abstract

A heat-preservation fireproof board is prepared by the following raw materials: 80-100 parts by weight of magnesium oxide, 2-3 parts by weight of dimethyl silicone oil, 4-6 parts by weight of aluminum nitride powder, 20-30 parts by weight of anhydrous magnesium chloride, 3-5 parts by weight of hollow glass beads, 8-12 parts by weight of tetrapod-shaped zinc oxide whiskers, 3-6 parts by weight of aerosil, 3-5 parts by weight of polyvinyl acetate emulsion, 20-30 parts by weight of refractory materials, 3-6 parts by weight of rock wool, 3-5 parts by weight of methylisothiazolinone, 2-4 parts by weight of ferriferrous oxide, 5-8 parts by weight of methyl sodium silicate, 1-2 parts by weight of sodium dodecyl benzene sulfonate, and 130-150 parts by weight of water. By virtue of adding the multiple types of refractory materials, the board can be high in burning point and good in flame retardation effect; and with the addition of the fly ash hollow beads, the board can be good in heat insulation effect and fine in fireproof effect. In brief, the board of the invention is a novel inorganic heat-preservation and heat-insulation building material integrating characteristics of heat preservation, heat insulation, high strength, fire prevention, water proofing, sound absorption, sound insulation, and decoration.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermal insulation and fireproof board and a preparation method thereof. Background technique [0002] Fire-resistant board, also known as fire-resistant board, is scientifically called thermosetting resin-impregnated paper high-pressure laminated board. It is a fire-resistant building material for surface decoration and is widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. [0003] Glass magnesium fireproof board has high temperature resistance, flame retardant, sound absorption, shock resistance, insect resistance, light anti-corrosion, non-toxic, tasteless and pollution-free, can be directly painted, directly veneered, can be air nailed, directly tiled, the surface has better Colorability, high strength, bending resistance and toughness, can be nailed, sawed, glued, and convenient for decorat...

AI Technical Summary

Problems solved by technology

[0004] The current glass magnesium fireproof board still has insufficient thermal insulation performance, can not meet the national goal of energy conservation and environmental protection, and has the disadvantages of insufficient strength and wear resistance, insufficient waterproof performance, and insufficient service life. It is necessary to further improve the performance of the board.
