Description
Technical Field
The invention relates to a high-adhesion silane modified polyether sealant for an assembly type building and a preparation method thereof, belonging to the field of assembly type building sealants.
Background
With the strong support of the country to the fabricated building, the fabricated building has a rapid development trend in recent years. The assembly type building sealant is more and more concerned and valued as a key matching material of the assembly type building. The fabricated building is formed by assembling prefabricated components on a construction site, joints exist among the prefabricated components, and sealing by using sealant is needed. In the 50-80 s of the 20 th century, fabricated buildings were once popular in China; but almost completely disappeared by the 80 s. Firstly, the structural strength of the fabricated building cannot be guaranteed; another problem is the lack of suitable siding joint sealant, which can result in significant leakage from fabricated structures and impede the development of such structures. With the development of green buildings advocated by the nation, the assembly type buildings are developed with opportunity again.
In recent development of building technology, building structures are gradually changed from rigid design to flexible design (frame type), and high-performance elastic sealants such as silicone sealant and polyurethane sealant are produced at the same time. However, these sealants also present some drawbacks in themselves that are difficult to overcome: the silicone sealant has excellent durability, but has the defects of poor pollution resistance, abrasion resistance, tearing strength and the like when being used for a concrete base material; the polyurethane sealant has better elasticity, low temperature resistance, wear resistance and cohesiveness, but has relatively poorer weather resistance, and is not suitable for being directly exposed on an outer wall with direct sunlight for construction. The novel silane modified polyether elastic sealant (MS sealant) adopts siloxane-terminated polyether as a basic polymer, integrates the performance advantages of silicone sealant and polyurethane sealant, has the performance advantages of weather resistance, durability, paintability, low contamination, low viscosity, high displacement, environmental protection and the like, and is more and more widely applied to concrete buildings.
At present, the prefabricated PC slabs are mostly in cement mortar and concrete structures, and the two-component MS glue is usually used for joint filling of PC buildings at present because the two-component glue is lower in modulus, higher in construction efficiency and less in construction loss. The most important is that the curing speed of the double-component glue is high, the strength can be formed within 24 hours, the integrity of the PC joint filling glue is ensured, and the problems that the glue cracks due to displacement in the curing process and the like are avoided. However, the two-component adhesive has poor adhesion and must be primed.
