Problems solved by technology

However, the traditional cement bonded mortar has the disadvantages of low bond strength, easy to fall off, high material finished product, low work efficiency, more labor, long construction period, high labor intensity, need to do interface treatment, dust and dust fall, etc., which are not environmentally friendly.
[0003] In order to solve the above technical problems, the prior art discloses bonding mortars containing new components. For example, CN102875101 discloses a water-resistant bonding mortar for external wall insulation, which is made of high alumina cement, Portland cement, sand, heavy Calcium and other components, which have excellent water resistance; but the bonding mortar disclosed in the prior art does not have sufficient tensile bonding strength to bond external wall insulation materials

Abstract

One aspect of the invention provides application of a polyurethane adhesive in adhering an exterior wall insulation material and a construction method of the polyurethane adhesive and provides a polyurethane adhesive for adhering an exterior wall insulation material. Compared with traditional cement mortar, the polyurethane adhesive has the advantages of high tensile adhesive strength, low material consumption, zero need of a wall for interfacial treatment, short curing time, good construction efficiency and the like.

Description

technical field [0001] The invention belongs to the field of polyurethane-based adhesives, specifically relates to a polyurethane adhesive, and provides the application and construction method of the polyurethane adhesive in bonding external wall insulation materials. Background technique [0002] The traditional bonding material for external wall insulation is cement bonded mortar. However, the traditional cement-bonded mortar has low bonding strength and is easy to fall off, the finished product is high, low work efficiency, many labors, long construction period, high labor intensity, interface treatment is required, dust and ash fall are not environmentally friendly, etc. [0003] In order to solve the above technical problems, the prior art discloses bonding mortar containing new components. For example, CN102875101 discloses a water-resistant bonding mortar for external wall insulation, which is made of high alumina cement, Portland cement, sand, heavy Calcium and othe...
