Description
Technical field
The present invention relates to a kind of polymer cement waterproof paints, and in particular to a kind of self-cure type polymer cement waterproof painting
Material.
Background technology
The bi-component water-proof that polymer cement waterproof paint is made of polymer emulsion, cement and a certain amount of additive
Coating, with high performance-price ratio, Diamond Search discharge, good water resistance, good moisture substrate workability and cementability
Can, therefore favored by people.Currently, polymer cement waterproof paint is usually used in Indoor environment waterproof, including toilet bath room, kitchen
Room and balcony etc., the domestic annual market demand is huge, up to 600,000 tons or so.Existing polymer cement waterproof paint is when by broken
Bad when, the waterproof layer of composition, which will fail, generates leakage phenomenon.In recent years, people develop self-closing polymer cement waterproof
Coating is crystallized caused by such suction-operated of water-repellent paint using active filler to calcium ion and is sealed to minute crack
It is stifled, to play leak-stopping water effect.
Currently, self-closing polymer cement waterproof paint can only accomplish minute crack to block leak-stopping water, it cannot at crack
Real self-healing healing, later stage can also have repeatedly the possibility of percolating water.Self-closing polymer cement waterproof in the prior art
Coating, such as CN101899243A, CN102320787A, CN104177007A and CN104194463A, they are so-called self-closing
Performance be all by active filler (such as penetrant crystalline masterbatch) to the suction-operated of calcium ion formed insoluble crystalline solid block it is micro-
Crackle cannot really generate self-healing phenomenon, there is repeatedly the danger of percolating water to be produced from apolipsis leak performance.
CN00123946.5 discloses a kind of self-repairing flexible water-proof material, made from which is blended with filler using water soluble polymer
Water-repellent paint has excellent self-healing performance, but water-repellent paint cannot contact water the long period, otherwise water soluble polymer
Material can be dissolved in water, then cause entire waterproof damage layer.
