Energy-saving environment-friendly light fireproof building material and preparation method thereof

Abstract

The invention discloses an energy-saving environment-friendly light fireproof building material and a preparation method thereof. The material comprises an inorganic gel material, a light filling material and an auxiliary additive, wherein the inorganic gel material comprises magnesium oxide and magnesium chloride; the light filling material comprises polyester fibers and light material wastes; the auxiliary additive comprises a CI (Cast Iron) modifier, a waterborne organosilicone protein former and a diffusant. The building material comprises the following components in parts by weight: 90-110 parts of magnesium oxide, 80-100 parts of 23% magnesium chloride, 1.2-2 parts of polyester fibers, 15-35 parts of light material wastes, 0.5-1.5 parts of CI modifier, 0.6-1 part of defoamer and 0.1-0.3 part of diffusant. The volume ratio of foam to the inorganic gel material slurry formed by white foam is (3-5):1. By adopting the scheme, the building material has the advantages of simple production process, convenience in processing, light volume-weight, high strength, good fireproof performance, heat insulation, strong weather ability, energy conservation and environment protection and the like, and can be widely applied to the building field and associated industries.

Description

technical field [0001] The invention relates to a lightweight fireproof building material, in particular to an energy-saving and environment-friendly lightweight fireproof building material used as a building partition wall and a fireproof partition and a manufacturing method thereof. Background technique [0002] The fireproof building materials produced in the early stage in China generally use calcium silicate board sandwiched with aluminum silicate cotton as filler. Although calcium silicate board sandwiched with aluminum silicate cotton has certain fire resistance performance, it also has good sound absorption and sound insulation effect and heat insulation performance. But there are also the following problems: first, the calcium silicate board is a low-temperature refractory material, which will melt when exposed to high temperatures and cannot achieve fire protection; second, the dust generated during the production and processing of aluminum silicate cotton will cau...

Problems solved by technology

[0002] The fireproof building materials produced in the early stage in China generally use calcium silicate board sandwiched with aluminum silicate cotton as filler. Although calcium silicate board sandwiched with aluminum silicate cotton has certain fire resistance performance, it also has good sound absorption and sound insulation effect and heat insulation performance. But there are also the following problems: first, the calcium silicate board is a low-temperature refractory material, which will melt when exposed to high temperatures and cannot achieve fire protection; second, the dust generated during the production and processing of aluminum silicate cotton will cause harm to the human body; third, The production and processing efficiency is low, the mechanical strength is low, and the anti-theft performance is poor; the fourth is that the raw materials are harmful substances of inorganic fibers, and long-term contact with such substances will cause harm to the human body and the environment

[0003] A Chinese patent discloses a light-weight sound-insulating, heat-insulating, and fire-proof building material and its manufacturing method. The patent number is 02108446.7. % (weight) of inorganic light particles and 30-60% (weight) of unsaturated polyester resin are stirred and mixed with each other, and then molded, so that the unsaturated polyester resin is glued and consolidated, and the inorganic light particles are further bonded Press the glass fiber cloth on both sides and the outer panel to make various light-weight sound-insulation, heat-insulation and fire-proof building materials of boards, strips and columns; but there are the following shortcomings in the process of production and use: First, inorganic light particles need high Catalysis, the production process is complex; second, the three wastes are discharged during the high-temperature catalytic process, and the environment is seriously polluted; third, the leftovers and scrapped products during product processing cannot be recycled.

For this reason, many manufacturers and people of insight have carried out research and development on the above-mentioned problems, but have not yet found a more reasonable product to come out.
