Heat insulation building material

Abstract

The invention relates to a heat insulation building material which comprises the following raw materials by mass percent: 20-40% of fine sand, 30-50% of cementing material, 10-40% of heat insulation material, 10-30% of mineral admixture and 5-10% of other auxiliary materials. A production technology of the heat insulation building material comprises the steps of mixing and stirring a shell cementing material, producing foam concrete, cutting and fixing the foam concrete and a heat insulation core body of a polystyrene foam plastic board, pouring, vibrating and molding shell slurry, and maintaining building blocks. The heat insulation building material can be used for replacing a great deal of solid clay bricks, thus saving a great deal of energy and land for China, being capable of consuming a great deal of industrial solid wastes and being beneficial to the environmental protection. The produced construction product has the excellent characteristics of being good in heat insulation property, light in self weight, high in strength, waterproof, impervious, low in shrinking percentage, long in service life, simple in construction and the like, thus being beneficial 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
