an insulating building material

Abstract

The invention relates to a thermal insulation building material. The raw materials are as follows according to mass percentage: fine sand accounts for 20-40%, cementitious material accounts for 30-50%, thermal insulation material accounts for 10-40%, and mineral admixture accounts for 10-30%. And other accessories accounted for 5 to 10%. The production process of the above thermal insulation building materials includes: mixing and stirring of shell cement, production and preparation of foam concrete, cutting and fixing of foam concrete and polystyrene foam board insulation core, pouring of shell slurry, vibration, Forming, maintenance of blocks. The product of the invention can replace a large number of solid clay bricks, save a large amount of energy and land for the country, and can consume a large amount of industrial solid waste at the same time, which is beneficial to environmental protection. The produced building products have excellent properties such as good thermal insulation performance, light weight, high strength, waterproof, impervious, low shrinkage, long service life, and simple construction, which is conducive to the development of building energy conservation.

Description

technical field [0001] The invention relates to a thermal insulation building material, which belongs to the field of building technology. Background technique [0002] At present, the state is vigorously promoting the use of new technologies, new processes, new materials and new equipment for civil building energy conservation. All countries in the world focus on the innovation of building envelope materials when developing building energy conservation. Some developed countries began to replace traditional building materials with new building materials with good thermal insulation performance and low energy consumption as early as the 1960s. In buildings, the heat loss of the outer envelope is the largest, and the building accounts for a large share of the outer envelope. The development of external wall protection technology and energy-saving materials is one of the main methods of building energy conservation. [0003] According to the different materials selected, buil...

Problems solved by technology

However, traditional blocks have weaknesses such as heavy blocks, easy to shrink and deform, poor thermal insulation performance, easy to break, and inconvenient to cut. Block products have limitations in production, architectural design, construction application technology, and quality management. Special requirements, if not handled properly, there may be cracks, leaks, heat and other construction quality problems
