Abstract

The invention discloses a silicone sealant base coat liquid suitable for a fiber cement board. The silicone sealant base coat liquid comprises the following raw materials in parts by weight: 5-15 parts of base resin, 2-8 parts of a crosslinking agent, 0.1-2 parts of a catalyst, 0.5-4 parts of a coupling agent and 70-95 parts of a solvent. The silicone sealant base coat liquid is available in raw material, low in cost, simple in preparation method, and convenient to construct; the water-resistant cohesiveness and the non-staining property of a silicone sealant are improved; other properties of the silicone sealant are not affected; and the problems of the water-resistant cohesiveness and the contaminativity of the silicone sealant on the fiber cement board are effectively solved.

Description

technical field [0001] The invention relates to the technical field of building sealing, in particular to a silicone sealant primer suitable for fiber cement boards. Background technique [0002] After vulcanization, silicone sealant has good UV resistance, displacement ability, elastic recovery ability, excellent adhesion and excellent weather resistance, etc. Therefore, silicone weather-resistant sealant has become the preferred sealing material in the construction and decoration industry. With the continuous development of building technology, building materials are changing with each passing day, so many new environmentally friendly building materials have emerged. Among them, fiber cement board is widely used in indoor and outdoor decoration of buildings because of its light weight, high strength, simple construction, economical and beautiful appearance. [0003] However, with the continuous emergence of new environmentally friendly building materials, the requirements...
