Insulation waterproof coating and construction process thereof

Abstract

The invention relates to an insulation waterproof coating and a construction process thereof. The insulation waterproof coating comprises a hard bubble layer formed by foaming isocyanate, polyalcohol, foaming agent, catalyst and flame retardant, and a sealing layer formed by spraying an inorganic fiber-blended water-based binder outside the hard bubble layer by an inorganic fiber sprayer outside a waterproof layer. The insulation waterproof coating has both the advantages of spraying the polyurethane hard bubble material and the inorganic fiber; thus, a continuous seamless seal integer is formed between the inorganic fiber spraying material and the polyurethane hard bubble material, which can effectively block the heat conduction, improve the energy saving effect and meet the mechanical demand of building surface. The insulation waterproof coating can also well reduce the noise generated during the running of vehicles, meet the fire resistance requirement because of the nonflammable material inside and be processed into different colors on the surface to be more beautiful and decorative.

Description

technical field [0001] The invention belongs to the thermal insulation and waterproof coating technology of buildings, and in particular relates to a novel thermal insulation and waterproof coating prepared by using two conventional waterproof and thermal insulation materials and its construction process. Background technique [0002] Existing buildings have been treated with a variety of polymer composite thermal insulation and waterproof materials as external thermal insulation systems. A better external thermal insulation system for buildings should have good thermal insulation performance, long service life, good bearing capacity and fire resistance. The components of the external thermal insulation system can be better matched, the thermal conductivity is low, and the waterproof, fire-resistant, breathable, weather-resistant, cohesive, and durable of the system are as high as possible. [0003] Spraying polyurethane rigid foam insulation has been widely used in buildin...

AI Technical Summary

Problems solved by technology

However, the sprayed polyurethane rigid foam insulation material has low tensile strength and low tear strength, which cannot meet the mechanical requirements of the superior roof, and it is easy to lose waterproof and corrosion resistance after being artificially stepped on.
