Problems solved by technology

[0004] The general wall insulation system uses a single ordinary expanded perlite or EPS 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 product In the later stage, the strength is low, there are phenomena such as hollowing and cracking, and low thermal insulation performance; the single EPS particle organic material has the disadvantage of poor construction
In the EPS board external insulation system, the difference in thermal conductivity between the EPS board and the two adjacent structural layers of the anti-crack mortar is too large, and cracks are prone to occur in severe cold regions, and the wind pressure resistance is poor, and it is easy to be eroded by insects and ants. The defects of harmful gas generation and low aging resistance

Description

technical field [0001] The invention relates to a wall thermal insulation rubber powder material, a preparation method and a use method thereof. Background technique [0002] Wall insulation technology is energy-saving, crack-proof, water-repellent and breathable, and is suitable for any new construction, renovation and expansion projects. The current wall insulation generally uses polystyrene boards. Due to the thermal insulation effect of polystyrene boards, the insulation system can keep warm in winter, meet the energy-saving requirements of heating buildings, and meet the heat insulation design requirements in summer. Therefore, according to the design requirements It can be used in areas that need heat preservation in winter and heat insulation in summer. [0003] The building wall adopts thermal insulation technology, which has many advantages. It not only significantly improves the living comfort, but also has very good energy-saving effect and comprehensive economic...
