Description

technical field [0001] The invention relates to the technical field of building sealants, in particular to a flame-retardant high-viscosity environment-friendly sealant. Background technique [0002] At present, most of the building sealants commonly used at home and abroad are polyurethane sealants and silicone rubber sealants. The production process of polyurethane sealant is complicated, the equipment requirements are high, and the investment is large. Moreover, due to the use of moisture curing principle, the storage stability of polyurethane sealant is poor. If the airtightness is not strict or the temperature is slightly high, it is easy to cure and fail. Polyurethane sealants have weak adhesion to vinyl materials such as PVC, EVA, PE and other common building materials, and the bonding strength often fails to meet the requirements. In addition, because the residual isocyanate of polyurethane sealant is harmful to human body, it is not environmentally friendly and has...
