Building environment-friendly thermal insulation material

Abstract

The invention discloses a building environment-friendly thermal insulation material. The thermal insulation material is prepared from the following raw materials in parts by weight: 2-5 parts of fly ash, 1-4 parts of sericite powder, 0.5-2 parts of wood fiber powder, 5-8 parts of polypropylene fibers, 10-15 parts of quick lime, 60-80 parts of a cementing material and 10-15 parts of perlite. A cutsection bar is conveyed to the lower part of a hairbrush through a conveying belt; a second rotating shaft is driven to rotate to drive the hairbrush to rotate, the hairbrush conveys dust into a collecting and drawing groove through an arc-shaped plate, finally, a finished product is conveyed out of a cutting box, through the arrangement of the arc-shaped plate and an inclined plate, dust can be conveniently collected, polished and cut chippings can be conveniently recycled, and environmental pollution caused by the chippings is avoided.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a building environmental protection thermal insulation material. Background technique [0002] Energy saving and environmental protection have become a major issue that human beings must face in the 21st century, and it has also become an important issue that our construction industry must focus on solving. Improving the thermal insulation performance of houses is an important measure for building energy saving and consumption reduction. Under the advocacy of the state, many new buildings and many old buildings are applying thermal insulation layers on the outer walls and inner walls to reduce energy consumption. To achieve the effect of heat insulation in the house, that is, to prevent heat radiation from being transmitted to the house through the heat insulation material of the inner and outer walls in hot summer, and reduce the energy consumption of househ...

AI Technical Summary

Problems solved by technology

Among them, the main advantages of organic material boards are low density, high heat preservation efficiency, and good toughness. The disadvantages are poor fire resistance, easy to ignite after fire, and will produce toxic smoke during the combustion process, which seriously endangers life safety, and also has aging resistance. Poor performance, short service life, complex installation procedures, high cost and other defects; at the same time, the insulation profiles prepared by the existing technology are not convenient to clean the debris after cutting and grinding;
