Thermal-insulation and flame-retardant building material and preparation method thereof

Abstract

The invention provides a preparation method of a thermal-insulation and flame-retardant building material and a preparation method thereof, relating to the field of building materials. The building material is prepared from the following raw materials in parts by weight: 45-65 parts of artificial aggregates, 50-60 parts of gel materials, 0.5-1.5 parts of anti-cracking fibers, 10-15 parts of aluminum silicate powder, 12-24 parts of calcium carbonate powder, 2-4 parts of a dispersing agent, 15-20 parts of asbestos, 20-30 parts of nano-silicon carbide, 0.5-1.5 parts of a defoaming agent, 0.5-1 part of a mortar water-retaining agent, 0.2-0.5 part of a water reducer, 11-16 parts of thermal-insulation cotton, 16-24 parts of fiber glass and 12-25 parts of water. The preparation method of the building material comprises the following steps: (1) adding the artificial aggregates, the gel materials, the anti-cracking fibers, the aluminum silicate powder, the calcium carbonate powder, the asbestos, nano-silicon carbide, the defoaming agent, the mortar water-retaining agent, the water reducer, the thermal-insulation cotton and the fiber glass into a stirring machine, and stirring for 30-40 minutes; and (2) adding water and the dispersing agent into the mixture obtained in the step (1), and stirring for 15-25 minutes. According to the preparation method, the problems that an existing thermal-insulation and flame-retardant building material is poor in thermal insulation property and flame retardance and low in compressive strength and tensile strength are solved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a heat-insulating and flame-retardant building material and a preparation method thereof. Background technique [0002] With the continuous development of social economy and science and technology, people's living standards are rapidly improving, and the requirements for building materials are more prominent. There are many types of new building materials in different forms, leading the development and improvement of modern building technology innovation trends.
