Problems solved by technology

These methods are all based on civil construction, and the process of splicing and gluing the insulation layer on site and adding the overall finish. There is a difference in expansion coefficient between the large-area organic material and the inorganic wall surface and the mortar surface layer. Not only the stress cannot be released, but the heat preservation The layer also bears the weight of 50 to 80 kilograms of mortar and facing bricks, which can easily cause cracking, water seepage and bulging and falling off of the wall surface, causing safety hazards
At present, EPS polystyrene board is the most common thermal insulation material sold in the market, but its most fatal disadvantage is that it is flammable, and the gas released during combustion is toxic and harmful to the human body and the environment.
Flame-retardant materials such as expanded perlite or vermiculite, asbestos, and calcium silicate boards have poor thermal insulation properties and are not light in weight
In short, the existing thermal insulation materials are not fireproof, and the fireproof materials are not thermally insulated, which poses a great safety hazard

Abstract

The invention provides a production method of a high-strength light environment-friendly insulation fire-proof plate, belonging to the technical fields of building material production and application. The method comprises the following steps: based on diatomite serving as the base material of the fire-proof plate, adding hydrophobic expanded perlite, macrofiber asbestos and ore binder attapulgitewith nano micropores and sodium silicate which are used as main raw materials; and mixing and stirring, carrying out injection molding, demoulding, conserving, coating cement, curing and shaping, so as to produce a finished product. The fire-proof plate is prepared from the following raw materials by weight percent: 20-30% of dry diatomite, 30-40% of 250 expanded perlite, 15-19% of 325-mesh attapulgite powder, 10-13% of asbestine, 10-11% of liquid sodium silicate and 1-2% of 425-numbered fire-resistant Portland cement. The production method has the advantages of saving the cost, reducing the consumption and improving the high value-added utilization of non-metal ore resources and being simple in process. The product is capable of preventing fire and preserving heat, has high strength and light weight, dose not generate toxic and harmful gases at high temperature, thereby being a high-quality cheap insulation fire-proofing material.

Description

technical field [0001] The invention relates to a production method of a fireproof board, in particular to a production method of a high-strength, light-weight, environmentally friendly and heat-preserving fireproof board. It belongs to the technical field of building material production and application. Background technique [0002] Existing building exterior wall and interior wall insulation mainly adopt the following methods: (1) First lay and paste EPS polystyrene board insulation material on the wall, then wipe the polymer cement mortar reinforced by grid cloth, and then carry out the external wall insulation. Coating or pasting bricks; (2) pouring the EPS polystyrene board of steel wire grid directly into the formwork, and then disassembling and plastering for exterior wall painting or pasting bricks; (3) thin plastering with polystyrene particle mortar for heat preservation, etc. These methods are all based on civil construction, and the process of splicing and gluin...
