Abstract
The invention discloses waterproof chloroprene rubber sealant. The waterproof chloroprene rubber sealant is prepared from the following materials in parts by weight: 18-22 parts of bonding type chloroprene rubber (CR2442), 80-90 parts of dimethylbenzene, 18-25 parts of acetone, 5-8 parts of aluminum hydroxide powder, 10-12 parts of coumarone resin, 3-6 parts of maleic anhydride, 6-8 parts of ethylene glycol, 5-6 parts of clay, 3-5 parts of vermiculite powder, 12-15 parts of zeolite powder, 1-2 parts of urotropine, 2-3 parts of polypropylene glycol acrylic ester, 4-6 parts of polyisobutene, 2-3 parts of tert-butyl peroxypivalate, 1-2 parts of aluminum oxide, 10-12 parts of heavy calcium carbonate, 3-5 parts of talcum powder, 3-5 parts of loess, 4-6 parts of methyl triethoxysilane and 1-2 parts of antioxidant DLTP (Dilauryl Thiodipropionate). The caking property of the waterproof chloroprene rubber sealant is increased by polymerizing aluminum hydroxide, maleic anhydride, ethylene glycol, coumarone resin and aluminum oxide, and modifying the bonding type chloroprene rubber (CR2442) by adopting methyl trimethoxy silane, methyl triethoxy silane and antioxidant DLTP ((Dilauryl Thiodipropionate). A network distribution structure is formed between an inorganic molecule and an organic molecule, so that water resistance, weather resistance, heat resistance and low-temperature resistance of the product are obviously improved. Besides, the adhesion is strong, the flexibility is better and the sealing performance is excellent.
Description
Technical field
