Preparation method of novel energy-saving flame-retardant building material

Abstract

The invention provides a preparation method of a novel energy-saving flame-retardant building material. The preparation method comprises 1, crushing magnesium oxide to obtain powder of 1800-2000 meshes, uniformly mixing the powder, magnesium sulfate and a building additive, and crushing the mixture to obtain mixture 1 powder of 3500-4200 meshes, 2, weighing silica powder and nanometer silicon carbide powder according to a mass ratio and dispersing the weighed silica and silicon carbide powder through anhydrous ethanol as a dispersion medium to obtain a mixture 2, 3, putting the mixture 2 into a nylon ball milling tank and carrying out ball milling through agate balls as grinding balls to obtain a mixture 3, 4, pouring the mixture 3 and the agate balls into a powder disc together, carrying out drying at 100-150 DEG C, carrying out screening, taking out the agate balls and carrying out grinding to obtain a mixture 4, and 5, uniformly mixing the mixture 1, the mixture 4 and graphene and carrying out pressing molding. The building material realizes a low cost, is prepared through simple processes, has good flame-retardant properties and has toughness and durability far greater than those of the same products on the market.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a novel energy-saving and flame-retardant building material. Background technique [0002] After the 1970s, the world's climate became warmer, and the earth's energy sources were increasingly exhausted. In my country's energy consumption, building energy consumption accounts for 30-40% of human energy consumption. Improving the thermal insulation performance of buildings is an important way to save energy and improve the function of buildings. Applying thermal insulation coatings to the surface of buildings can effectively reduce the temperature on the surface and inside of buildings. In recent years, with the popularization of building energy conservation, thermal insulation coatings have attracted more and more attention due to their advantages of economy, convenience and good thermal insulation effect. Therefore, the research an...

Problems solved by technology

In order to meet the basic physical and chemical performance requirements of ordinary exterior wall coatings, this type of existing traditional thermal insulation coatings must ensure a relatively high addition of organic polymer emulsions in the coatings, resulting in unsatisfactory thermal insulation effects

And it does not have anti-crack performance, so it has received many restrictions in use
