Insulation material having air purifying function and preparation method thereof

Abstract

The invention provides an insulation material having air purifying function and a preparation method thereof, which relate to the field of the insulation material. The insulation material comprises the following raw materials in parts by weight: 14-20 parts of calcium silicate powder, 10-28 parts of granite powder, 15-17 parts of polyurethane, 17-23 parts of alumina silicate powder, 5-9 parts of magnesium oxide, 7-13 parts of mineral wool, 4-8 parts of polyester fiber, 21-35 parts of bamboo charcoal, 7-13 parts of bentonite, 9-13 parts of meerschaum powder, 15-19 parts of phenolic foam, 11-31 parts of vermiculite, 15-21 parts of waste polyethylene foamed plastic, 9-15 parts of boron fiber, 13-21 parts of polyacrylonitrile fiber, 27-35 parts of cement, 0.2-0.4 parts of an air-entrainer, 0.1-0.7 parts of a delayed coagulant, 0.1-0.3 parts of a heat stabilizer, 0.3-0.7 parts of a water reducer, 0.2-0.6 parts of a foaming agent, and 4-8 parts of water. The preparation method comprises the following steps: 1) raw material weighing; 2) roasting; 3) crushing; 4) stirring; 5) pressurization moulding; and 6) drying. The insulation material has the advantages of high intensity, good heat insulation performance, environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, and in particular relates to a thermal insulation material with the function of purifying air and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, people's requirements for building materials are getting higher and higher, especially the insulation materials in building materials. However, in the existing insulation materials, there are low compressive strength and tensile strength. Low strength, general thermal insulation effect and failure to meet the requirements of energy conservation and environmental protection. [0003] In the Chinese patent document published on July 13, 2016, a thermal insulation building material and its preparation method (authorized announcement number CN104261776B), the thermal insulation building material includes the following raw materials by weight: calcium silica...
