High strength energy saving heat insulation material for use outside external wall

Abstract

The heat insulation material consists of cement 50-55 wt%, granular polystyrene 10-15 wt%, flyash 20-25 wt%, light calcium carbonate 1-5 wt%, heavy calcium carbonate 5-10 wt%, flyash 10-20 wt%, cellulose fiber 0.1-0.5 wt%, methyl cellkulose 0.1-0.3 wt%, amylase 0.1-0.2 wt%, foaming agent 0.1-0.2 wt% and air entraining agent 0-0.2 wt%. The present invention is a kind of green furnishing and decorating material and is suitable for use as heat insulating material outside the outer wall and roof.

Description

technical field [0001] The invention relates to a wall thermal insulation material. Background technique [0002] Wall insulation is a necessary measure for building energy saving and consumption reduction. Existing wall insulation materials contain not only cement and polystyrene particles but also some carcinogenic and radioactive substances harmful to human body, such as sepiolite and asbestos. After the country restricts the use of these two substances, it is urgent to develop a non-toxic and harmless wall insulation material that does not contain sepiolite or asbestos. Existing wall insulation materials are prepared at the construction site, the measurement is inaccurate, the thermal insulation performance and adhesion are poor, and the walls often appear hollow, cracked, pulverized, and dewed, so they cannot be used for external insulation construction of external walls. It is necessary to adjust the ratio of existing wall insulation materials. Contents of the inven...
