Problems solved by technology

[0005] Generally, the wall insulation system uses a single ordinary expanded perlite or polystyrene particles as the lightweight aggregate of the thermal insulation mortar. The expanded perlite lightweight aggregate has high water absorption, is easy to pulverize, and has a large volume loss rate during slurry construction. The strength of the product is low in the later stage, there are phenomena such as hollowing and cracking, and low thermal insulation performance; the organic material of single polystyrene particles has the disadvantages of low compressive strength and poor constructability

Description

technical field [0001] The invention relates to a heat-insulating, energy-saving and environment-friendly rubber powder material for interior walls, a preparation method and a use method thereof. Background technique [0002] my country has now taken resource conservation as a basic national policy, and the importance of energy conservation has risen to a strategic and overall level. The pace of energy saving work is getting faster and faster. Building materials is an important industry for the development of circular economy in my country. Many industrial wastes can be used as alternative raw materials for the production of building materials. The comprehensive utilization of industrial waste is a way to develop a circular economy and build a resource-saving and environment-friendly building materials industry. By expanding the use of industrial solid waste as alternative raw materials in the building materials industry, we will vigorously develop materials with thermal ...
