Preparation method of novel energy-saving and environment-friendly building material

Abstract

The invention provides a preparation method of a novel energy-saving and environment-friendly building material. The preparation method comprises the following steps of 1, adding nanometer oxide into a dispersing machine, stirring and preheating, slowly adding fire-refractory material into the dispersing machine, dispersing and stirring, so as to obtain a mixture I; 2, taking silicon dioxide powder and nanometer silicon carbide powder, using absolute ethyl alcohol as a dispersing medium for the silicon dioxide powder and nanometer silicon carbide powder, and dispersing, so as to obtain a mixture II; 3, adding a water-soluble adhesive (hydroxypropyl methyl cellulose) into the mixture II, and performing ball milling, so as to obtain a mixture III; 4, pouring the mixture III into a powder tray, drying, filtering, and grinding, so as to obtain a mixture IV; 5, uniformly mixing the mixture I, the mixture IV and modified starch, pressing, and forming. The preparation method has the advantages that the cost of building material is low, the preparation method is simple, the energy-saving and emission-reduction effects are realized, and the good flame-retardant property of the prepared product is very good.

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 environment-friendly 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 resear...

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
