One-component silane-modified sealant for industrial buildings

Abstract

The invention discloses a single-component silane-modified sealant for industrial buildings, which uses silane-modified polymer resin, adds nano-calcium, graphene powder, nano-pigment, fumed silica, chopped fiber, silver powder paste, weather resistance Auxiliaries, catalysts, etc., are prepared by double planetary vacuum stirring process. The product of the present invention has reliable sealing and bonding, good durability, and solves the problems of insufficient curing strength, low elastic recovery rate, poor shear resistance, and Poor weather resistance and other issues. This product adopts cleaning, pretreatment, primer, scraping and other technical construction techniques on the PC building joints to ensure reliable waterproof quality of the building joints. The invention has good economic and social benefits.

Description

technical field [0001] The invention relates to a sealing material and a preparation process thereof, in particular to a single-component silane-modified sealant for industrialized buildings, and belongs to the technical field of bonding and sealing materials in the construction industry. Background technique [0002] Industrialized buildings, also known as prefabricated buildings, are concrete structure buildings that are mainly manufactured with factory-produced prefabricated concrete components and constructed by on-site assembly. Compared with traditional cast-in-place concrete structures, it has the advantages of all six, safety and environmental protection, fast and efficient. The construction method of prefabricated buildings is on-site assembly and splicing, so the quality of the joints will directly affect the long-term life and safe use of the entire building. At present, the waterproofing of the joints of the external walls of building structures mainly adopts do...

Problems solved by technology

[0009] Aiming at the above-mentioned problems and hidden dangers in the prior art, the present invention discloses a new type of one-component silane-modified sealant for industrial buildings, preferably one-component silane-modified polymer resin MS510 specially used in the field of prefabricated buildings. Add chopped fiber to improve the shear and tear strength of the colloid; remove the adhesion promoter and water remover in the prior art, and strengthen the internal crosslinking strength of the colloid; introduce silver powder paste to shield water vapor and corrosive media with the help of anode metal aluminum sheets and ultraviolet light impregnation; use graphene performance enhancement and thermal conductivity, and cooperate with ultraviolet light absorbers, antioxidants, light stabilizers and anode metal sheets to shield ultraviolet rays and quickly absorb the heat absorbed by the surface of the colloid to the deep layer transfer, significantly improving the weather resistance of the colloid; in addition, for the existing one-component silane modified sealant dispersed into a paste at high speed, there will be different degrees of component precipitation after being placed for a period of time, which will affect the internal quality of the product and the mechanical properties after curing. The problem of hidden dangers, the present invention preferably uses fillers and emulsifiers to solve it; the present invention also provides the construction technology of this single-component silane modified sealant on the joints of PC buildings, using cleaning, pretreatment, primer, etc. , scraping glue and other technical measures to ensure the reliable quality of this single-component sealant for building joint protection and waterproofing
