Novel building heat-preservation and anti-seismic material and preparation method thereof

Abstract

The invention belongs to the field of building materials, and particularly relates to a novel building heat-preservation and anti-seismic material and a preparation method thereof. The novel buildingheat-preservation and anti-seismic material is prepared from the following components in parts by mass: 30-100 parts of straw, 20-80 parts of rubber powder, 60-250 parts of magnesium oxide, 20-80 parts of magnesium chloride, 50-215 parts of water, 7-28 parts of urea formaldehyde resin, 4-20 parts of ferrous sulfate, 2-10 parts of silicone acrylic emulsion, and 0.1-1.0 part of an additive. The preparation method comprises the following steps that raw materials are weighed, the magnesium chloride, the urea formaldehyde resin, the ferrous sulfate and the silicone acrylic emulsion are dissolved inwater and mixed, and even stirring is conducted to obtain a mixed solution; the straw and the rubber powder are mixed and evenly stirred, and a mixture is obtained; the magnesium oxide is added intothe mixed solution, sufficient and even stirring is conducted to form slurry; the mixture is added into the slurry, and even stirring is conducted to form a mixed material; and a mold is evenly filledwith the mixed material, after cold press molding, demolding is conducted, curing is conducted in air until the age is reached, and thus the novel building heat-preservation and anti-seismic materialis obtained. The novel building heat-preservation and anti-seismic material has the characteristics of low volume weight, high strength, low heat conductivity coefficient, good waterproof, fireproofand anti-corrosion performance, and the like.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a novel building thermal insulation and anti-seismic material and a preparation method thereof. Background technique [0002] Straw, as a kind of renewable resource, has a wide range and a large amount. my country is a large agricultural country with an annual output of more than 700 million tons of straw. Except for a small amount of straw that is returned to the field and made into paper, a large amount of straw that rots itself or is burned not only pollutes the environment but also wastes valuable resources with good application prospects. Rubber powder is taken from waste tires, which is an industrial by-product. Our country produces 500 million kilograms of rubber powder every year, and the annual output of concrete is 2 billion cubic meters. In theory, only 0.25 kilograms of rubber powder is added to each cubic concrete to consume it. In general, mixing rubbe...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the research on straw and rubber powder in building materials is relatively simple, and there are few researches on the combination of the two with inorganic cementitious materials, and the research cost of using polymer binders for thermocompression molding is high, and it also increases the process. complexity of
