Abstract

The invention relates to organic silicon resins, and discloses a quick-drying building sealant composition. The quick-drying building sealant composition comprises the following components in percentage by weight: a, 5-15% of an organic silicon resin GS-WKZM, b, 20-30% of an organic silicon resin GS-QL5000, c, 3-55 of a dimethicone diluent DMS-100, d, 20-25% of filler nano-calcium T1-101A, e, 20-30% of filler nano-calcium carbonate GS-TC80, f, 6-10% of GS-HS01 white cream, g, 2.5-5% of a crosslinking agent D-20, h, 0.1-0.2% of a curing agent S-210, i, 1-2% of an organic catalyst T-IBAY, j, 0.1-1% of a coupling agent, 0.01-0.02% of a catalyst T-12, l, 0.001-0.003% of a catalust T-440, and m, 0.5-2% of a free radical scavenger; and through kneading the components a to e by adoption of a vacuum kneading machine, rolling the kneaded components by a three-roller machine for twice, adding the component f by adoption of a planetary mixer, gradually adding the components g to h, I, j and l after uniformly mixing, adding the component n after the mixing, and carrying out sufficient mixing, the quick-drying building sealant composition is obtained. According to the quick-drying building sealant composition, the curing speeds of building adhesives are greatly improved and the cost is low.

Description

technical field [0001] The building material of the invention particularly relates to a building sealant. Background technique [0002] The curing time of building sealants used in the construction industry is often too long, which has become a bottleneck to speed up construction. Dow Corning's 7091 resin can improve curing speed and adhesion compared with general commercial products, but it can't do anything about the increasingly tight construction period. In addition, the high price of imported products also affects the cost of construction enterprises. Contents of the invention [0003] The present invention aims to overcome the above-mentioned defects of the prior art, and provides a quick-drying building sealant composition. The invention greatly improves the curing speed of the construction adhesive and has low price. [0004] A quick-drying building sealant composition of the present invention comprises: [0005] a, silicone resin GS-WKZM 5-15%, [0006] b, si...
