Problems solved by technology

[0009] Although the technology continues to improve, green and environmentally friendly building materials have gradually become a tumor product in the market. The thermal insulation material not only focuses on the thermal insulation effect, but also pays attention to the functional role of the thermal insulation material (such as adsorbing harmful substances, etc.). Patent document CN109336530B discloses a Recycled thermal insulation materials from construction waste have the effect of adsorbing formaldehyde. However, in the face of today's increasingly brutal market competition environment, the thermal insulation material's adsorption effect on formaldehyde is not particularly ideal, and there is still a need for further improvement.

Abstract

The invention relates to an environment-friendly building thermal insulation material, which comprises the following raw materials in parts by weight: 60 parts of recycled building waste materials, 10 parts of ordinary portland cement, 3 parts of quicklime, 10 parts of modified diatomite and 4 parts of lignocellulose. The thermal insulation material of the present invention has good heat insulation and thermal insulation effects, and on the basis of ensuring the thermal insulation and thermal insulation effects, further improves the formaldehyde adsorption effect of the thermal insulation material, and can effectively reduce indoor pollution. The preparation process of the invention is simple, the sources of raw materials are wide, the product cost is low, and problems such as wall cracking and bubbling do not occur.

Description

technical field [0001] The invention relates to an environment-friendly building thermal insulation material. Background technique [0002] Thermal insulation material is a new type of building material that integrates decoration and heat preservation. Due to the large number of micropores inside it, compared with solid bricks, the thermal conductivity of the brick body is greatly reduced, and the thermal insulation performance is enhanced; at the same time, the brick body can be glazed, etc. After surface treatment, no other wall treatment is required, and it has the characteristics of light weight, heat insulation, heat preservation, and sound absorption, which is of great significance to saving energy and promoting the sustainable development of the country. [0003] The origin of thermal insulation materials can be traced back to the 1950s, when my country began to manufacture hollow bricks, but due to economic and technological constraints at that time, the development ...
