Abstract
The invention provides polymer modified external wall heat insulation anti-crack mortar, which uses cement as a base material and consists of auxiliary hydrophobic active chemical substances and other corresponding chemical additives. A waterproof function is realized in such a way that the hydrophobic active chemical substances can be adsorbed on the inner surfaces of capillary pores inside cement mortar and concrete, and hydrophobic surface membranes are formed, so external moisture can be prevented from permeating inside the mortar and the concrete, the waterproof and anti-permeability effects are reached, and the flexibility, the impact resistance, the fatigue resistance and the anti-seismic performance of the mortar are improved.
