Example Embodiment

[0011] The specific implementation method of the present invention: pulverize the collected polyurethane rigid foam waste and mix it with 325# Portland cement mortar. The mixing ratio is: volume ratio, 1 part cement mortar is mixed with 1 part polyurethane rigid foam particles, It can be used after mixing well.

[0012] The invention can be used for the plastering layer of ordinary walls, and can also be used for plastering construction directly on the wall insulation layer, and the plastering effect for the polyurethane rigid foam insulation layer is the best.

Abstract

Disclosed is an anti-cracking cement mortar characterized in that, the cement mortar is charged by polyurethane hard bubble particles, wherein the volume proportion of the charged polyurethane hard bubble particles being, 1-2 parts of polyurethane hard bubble particles in 1 part of cement mortar.

Description

1. Technical field [0001] The invention relates to building wall plastering cement mortar, in particular to an anti-cracking cement mortar. 2. Background technology [0002] Microcracks and wind cracks in the cement mortar plastering layer of buildings have always been a difficult problem in the construction industry. The industry standard of the People's Republic of China "Design Standards for Energy Conservation of Residential Buildings in Hot Summer and Cold Winter Areas" (JGJ134-2001) has been implemented since October 1, 2001. It is mandatory for external walls of buildings to be thermally insulated to fully realize building energy conservation. 50% of the second-step strategic goals. Since then, walls with insulation layers are very common, and it is easier to crack when plastered with cement mortar on the insulation layer, which further increases the difficulty of crack resistance. Usually, it is not allowed to directly use ordinary cement mortar for plastering const...
