Abstract

The invention discloses a multipolymer type waterproof sealant for construction, wherein raw materials in a prescription based on ratio of part by weight are as follows: vinyl acetate, organic silicone monomer containing unsaturated double bonds, vinyl versatate, butyl acrylate, 2-ethylhexyl acrylate, acrylic acid and de-ionized water. The multipolymer type waterproof sealant has the advantages that the sealant can be used for coating surfaces of substances such as cement components, ceramics, glass, plywoods, shaving boards, palm fiber boards, bamboo slag boards, paper slag boards, composite boards, aluminum-plastic panels, polyvinyl chloride (PVC) boards, fireproof plates, metal, plastics, leather, rubber and the like and has the bonding strength that other waterproof materials cannot reach; the sealant has good stability and the shelf life at 5-35 DEG C. is more than 12 months; and the multipolymer type waterproof sealant for the construction has the advantages of no toxicity, no odor, no pollution, no corrosion, no combustion, no wiredrawing during coating and the like; and the problems of easy combustion, short shelf life, wiredrawing during coating, serious air pollution and the like during applications of solvent type materials, polyester type materials and the like are solved.

Description

technical field [0001] The present invention relates to a kind of water-based adhesive, more specifically, it relates to a kind of water-based brushing type glue for waterproofing and repairing leaks used for building decoration Background technique [0002] The construction waterproof adhesive we usually refer to refers to a type of water-based adhesive commonly used in the construction, decoration and construction maintenance industries. It is named for its wide bonding range and ease of use. The main components of early construction waterproof glue are neoprene, asphalt, polyurethane, etc., and toluene, xylene, methylene chloride, and chloroform are generally used as solvents. Because these substances are harmful to the body, their use has been banned abroad, but domestic short-term It will not withdraw from the interior decoration market. [0003] With the GB18583-2008 mandatory standard promulgated by the country, the adhesives used for interior decoration that use ben...
