Description
Technical field [0001] The invention relates to a wall insulation material. Background technique [0002] Wall insulation is a necessary measure for building energy saving and consumption reduction. The existing wall insulation materials have unsatisfactory thermal insulation performance, and contain some carcinogenic, radioactive substances that are harmful to the human body or can cause the strength of the insulation wall to decrease, such as sea Foam and asbestos. After the country restricts the use of these two substances, it is urgent to develop a wall insulation material that does not contain harmful substances. Existing wall insulation materials are prepared at the construction site, the measurement is not accurate, the thermal insulation performance and adhesion are poor, the wall often has hollowing, cracking, chalking, and condensation. It is necessary to adjust the existing wall insulation materials. Matching ratio. Summary of the invention [0003] The purpose of the...
