Abstract

The invention relates to the technical field of high polymer materials, in particular to an MS sealant and a preparation method thereof. The MS sealant at least comprises the following components in parts by weight: 20-30 parts of silane-terminated polyether, 10-20 parts of polyether polyol and 54.5-64.5 parts of a filler. According to the invention, the MS sealant is prepared from the silane-terminated polyether, the polyether polyol and the filler; the silane-terminated polyether, the polyether polyol and the filler have a good synergistic effect; and the prepared MS sealant is free of toxicity, friendly to environment and peculiar smell, high in adaptability to substrates, capable of being well bonded with various substrates, firm in bonding, excellent in ageing resistance, long in service life, operable in water, convenient and simple to construct and excellent in waterproof performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, more specifically, the invention relates to a MS glue and a preparation method thereof. Background technique [0002] Waterproof materials refer to materials that can prevent the leakage of rainwater, snow water or groundwater. At present, the waterproof materials used in the market mainly include polyurethane waterproof coatings, acrylic waterproof coatings, polymer waterproof coatings, and asphalt waterproof coatings. [0003] Polyurethane waterproof coatings are prepolymers containing isocyanate groups formed by addition polymerization of isocyanate and polyether, together with catalysts, anhydrous additives, anhydrous fillers, solvents, etc., and processed through mixing and other processes One-component polyurethane waterproof coating. Polyurethane waterproof coatings are generally made of polyurethane and asphalt as raw materials. When using such coatings, they are generally dil...
