Abstract

The invention discloses self-repair reaction type polymer cement waterproof coating and a method for preparing the same. The self-repair reaction type polymer cement waterproof coating comprises double components including liquid and powder, and particularly comprises, by weight, 35-50% of polymer liquid, 15-30% of cement, 10-30% of powdery fillers and 5-15% of micro-capsule materials on the basis of the total weight of 100%. According to the technical scheme, the self-repair reaction type polymer cement waterproof coating and the method have the advantages that water absorption materials with swelling properties wrap materials with quick curing and gelating properties by the aid of micro-capsule technologies, the materials with the quick curing and gelating properties can be uniformly dispersed in the self-repair reaction type polymer cement waterproof coating, capsules inside the self-repair reaction type polymer cement waterproof coating can be exposed from fracture when the self-repair reaction type polymer cement waterproof coating is broken by base layers by means of drawing, the water absorption wall materials of the self-repair reaction type polymer cement waterproof coating can be softened, swollen and broken after absorbing water, internal repair materials can flow out and can be quickly cured and gelated when in contact with the water, accordingly, crack can be blocked, self-repair effects can be conveniently, easily, timely and automatically realized without influence on the quality of polymers in the self-repair reaction type polymer cement waterproof coating and the performance of the self-repair reaction type polymer cement waterproof coating, and the self-repair reaction type polymer cement waterproof coating and the method are applicable to polyurethane, acrylic acid and epoxy polymers.

Description

technical field [0001] The invention belongs to the field of architectural waterproof coatings, in particular to a self-repairing reactive polymer cement waterproof coating and a preparation method thereof. Background technique [0002] Waterproof coating The waterproof film formed by the coating on the base layer after curing has certain strength, good extensibility, crack resistance, impermeability and weather resistance, and has good temperature adaptability, easy operation and easy maintenance. and maintenance. Compared with the waterproof membrane, the waterproof coating has strong adaptability to the base layer, and the waterproof layer has no seams, which is more reliable. Due to the above characteristics, waterproof coating is one of the main waterproof materials often used in waterproofing projects. [0003] Reactive polymer cement waterproof coating, as an improved variety of polymer cement waterproof coating, is a high-solid content coating that reacts and solid...
