Fireproof thermal insulation building material and preparation method thereof

Abstract

The invention belongs to the field of building decoration materials, and discloses a fireproof thermal insulation building material and a preparation method thereof. The material is prepared from sepiolite, Qi cotton, porous powder quartz, ceramic fiber, bentonite, a wetting agent, a binding agent, graphene, fire retardant, methyl silicone oil, methyl alkoxy silicone oil, amino silicon oil, polyethylene glycol, an emulsifier, fungicide, bagasse, rice hulls, rice bran, biomass insulation material additives, expanded perlite, vermiculite, quicklime, gypsum, straw stalk and rape stalk. The material has the thermal insulation and cold insulation effects, by using the building material, the thickness of the wall can be reduced, the thermal insulation and cold insulation effects are achieved, and the building material can be greatly saved. The paint is excellent in performance, good in freezing resistance and free of cracking and deformation; the fire retardant adopted by the building material adopts tetrabromobisphenol A, and the fire retardant is one of the fire retardant products which are most scientifically tested and have the highest cost advantage in the market.

Description

technical field [0001] The invention belongs to the field of building decoration materials, and in particular relates to a fireproof and thermal insulation building material and a preparation method thereof. Background technique [0002] The country has been vigorously promoting the use of new technologies, new processes, new materials and new equipment for civil building energy conservation. All countries in the world focus on the innovation of building envelope materials when developing building energy conservation. Some developed countries began to replace traditional building materials with new building materials with good thermal insulation performance and low energy consumption as early as the 1960s. In buildings, the heat loss of the outer envelope is the largest, and the building accounts for a large share of the outer envelope. The development of external wall protection technology and energy-saving materials is one of the main methods of building energy conservati...

Problems solved by technology

Invention patent (CN102120775A) discloses a method for improving the thermoplasticity of rice straw acetylation. The crushed rice straw is pretreated with a certain amount of glacial acetic acid for 0.5h, and then a certain amount of acetic anhydride and catalyst concentrated sulfuric acid are added to react to form straw acetylation products. , the obtained product can be hot-pressed into boards, the preparation method is cumbersome, not conducive to industrial production, the product has poor thermal insulation performance, and the use of various chemical reagents is also not conducive to human health; invention patent (CN104827545A) discloses rice straw The preparation method of bricks and its products and applications. The rice straw bricks treated with sodium hydroxide are made into straw straw bricks under the action of pressure. Although the method is simple, the products produced have certain thermal insulation properties, but the products absorb water High rate, easy to breed mold, limited use

[0017] At present, part of the bagasse in my country is used as fuel, which wastes bagasse resources and produces a large amount of CO 2 and other greenhouse gases, causing serious pollution to the air and natural environment

[0018] To sum up, the problems existing in the prior art are: the existing fire-proof and thermal-insulation building materials are too light, and when they are mixed with cement and other building materials to prepare insulation boards and other materials, they are easy to drift up, resulting in uneven mixing. The prepared insulation board has more foam on one side and less foam on the other side, which reduces the strength of the insulation board and greatly reduces the insulation effect

In addition, after the combination of foam and cement, as time goes by, the moisture in the cement will gradually lose, and the foam and cement will peel off, making the insulation effect of the insulation board worse and the strength reduced

And the flame retardant effect is low, and the fire prevention effect is poor
