Abstract

The invention relates to a self-adhesion reactive, water-swellable and waterproof sealing material and a production method thereof. Butyl rubber is used as the matrix of the self-adhesion reactive, water-swellable and waterproof sealing material, and other raw materials comprise polyisobutene, amorphous alpha-olefin copolymer, desulfuration gypsum, bentonite, tackifying resin, lithium chloride, calcium chloride, calcium stearate and a crosslinking agent, and counted in parts by weight, the proportions of the components are as follows: 50-100 parts of butyl rubber (IIR), 50-120 parts of polyisobutene, 5-10 parts of amorphous alpha-olefin copolymer, 100-180 parts of desulfuration gypsum, 80-120 parts of bentonite, 12-25 parts of tackifying resin, 0.1-2 parts of lithium chloride, 1-10 parts of calcium chloride, 0.08-1.2 parts of calcium stearate and 0.5-3 parts of crosslinking agent. By adopting the self-adhesion reactive, water-swellable and waterproof sealing material provided by the invention, the utilization range of the solid waste desulfuration gypsum is expanded, the problem that the existing waterproof sealing product cannot generate a chemical crosslinking reaction with concrete is solved as well, the two components are organically combined to turn waste into wealth, and the self-adhesion reactive, water-swellable and waterproof sealing material with a self-recovery function is innovatively provided.

Description

1. Technical field [0001] The invention relates to the field of building waterproof sealing, in particular to a self-adhesive reactive water-swellable waterproof sealing material and a production method thereof. 2. Background technology [0002] my country's power industry is a large coal consumer. The annual coal consumption accounts for about 60% of the total, and the sulfur dioxide emissions account for about 50% of the total emissions. In recent years, with the continuous improvement of national environmental standards, the thermal power plant sulfur dioxide There are also stricter regulations on the emission concentration of sulfur dioxide, which will greatly reduce the emission of sulfur dioxide in our country. The flue gas desulfurization method used in thermal power plants accounts for more than 80% is the wet limestone-gypsum method, which also leads to desulfurization gypsum becoming the second largest solid waste in thermal power plants after fly ash, and a large a...
