Wall heat insulating material and preparation method therefor

Abstract

The invention provides a wall heat insulating material and a preparation method therefor and relates to the field of building materials. The wall heat insulating material is prepared from the following raw materials in parts by weight: 16-20 parts of calcium silicate powder, 10-26 parts of granite powder, 15-17 parts of polyurethane, 17-21 parts of aluminum silicate powder, 5-7 parts of magnesia, 7-11 parts of mineral wool, 11-21 parts of furnace slag powder, 15-17 parts of glass fibers, 11-29 parts of vermiculite, 15-21 parts of aerogel, 15-21 parts of polyethylene foam plastics, 22-34 parts of meerschaum, 13-21 parts of polypropylene fibers, 27-31 parts of cement, 0.2-0.6 part of air entraining agent, 0.1-0.5 part of setting retarder, 0.1-0.3 part of thermal stabilizer, 0.5-0.9 part of water reducing agent, 0.2-0.6 part of foamer and 3-9 parts of water. The preparation method comprises the following steps: (1) raw material weighing, (2) roasting, (3) stirring, (4) extrusion forming, and (5) baking. According to the wall heat insulating material and the preparation method therefor, the problem that defects are still present when the existing wall heat insulating materials are applied to buildings with high requirements on compressive strength, tensile strength and heat preservation and insulation is solved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a wall thermal insulation material and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, people have higher and higher requirements for building materials, especially wall insulation materials in building materials.
