Problems solved by technology

[0004] my country's thermal insulation materials are currently in a period of development. Although some gratifying progress has been made, the overall technical level is backward, especially in the research and development of slurry thermal insulation materials.
At present, a large number of slurry thermal insulation materials used in civil engineering in my country are still dominated by traditional slurry expanded perlite thermal insulation materials, which have a high water absorption rate, poor crack resistance and weather resistance, and have great limitations in application. It needs to survive many times, and the construction efficiency is low. The insulation mortar is prepared on site, and its quality is not easy to control and guarantee

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a graphene-modified slurry thermal insulation material. Background technique [0002] After the 1970s, foreign countries generally paid attention to the production of thermal insulation materials and their application in construction, and strived to greatly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The thermal insulation material industry in foreign countries has a long history, and thermal insulation materials for building energy conservation account for the vast majority. Cotton products are used for energy saving in buildings. [0003] Building energy conservation is not only the promulgation and implementation of building energy conservation laws and regulations, but its realization also involves a huge industrial group, among which thermal insulation materials and products are an...
