The invention relates to thermoplastic macromolecule waterproof coatings, in particular relates to a thermoplastic macromolecule waterproof coating capable of being subjected to microwave heating and a preparation method thereof. The macromolecule waterproof coating capable of being subjected to microwave heating is prepared by shearing at high temperature and stirring the following components in percentage by weight: 10-50 percent of elastic thermoplastic polymer, 20-60 percent of asphalt, 5-20 percent of diluting agent, proper amount of compatilizer and 6-30 percent of absorption microwave materials. The absorption microwave materials comprise 0.5-5 percent of conducting polymer and 5-25 percent of waste vulcanized rubber powder. The macromolecule waterproof coating can be formed by the first time, so that the working period is greatly shortened, a sealing basic layer is effectively solved, the tension fracture of a waterproof layer caused by cracking of the basic layer is overcome, and the waterproofing reliability is improved; and meanwhile, the macromolecule waterproof coating can be used for multiple purposes to fully play a role in the advantages and the characteristics of respective materials, so that the process is simple and convenient, the macromolecule waterproof coating can be quickly constructed, the maintenance is avoided, and the working period is short.

A recycled crumb rubber coating with a hydrophobic surface and a method for making the same. The coating with a hydrophobic surface includes a recycled crumb rubber coating layer comprising about 24-50 wt % of a crumb rubber, and about 25-75 wt % of an epoxy comprising a liquid epoxy resin and an epoxy hardener, and a first silane film comprising at least one silane and disposed on a surface of the recycled crumb rubber coating layer to form the hydrophobic surface. The method includes (a) mixing a crumb rubber with a liquid epoxy resin to form a first mixture, (b) mixing the first mixture with an epoxy hardener to form a recycled crumb rubber coating layer, and (c) depositing a first silane film comprising at least one silane on a surface of the recycled crumb rubber coating layer to form the hydrophobic surface of the recycled crumb rubber coating.

EPDM waterproof coating and preparation process thereof, the dry raw materials of the waterproof coating consist of 5-7 parts by weight of EPDM rubber, 10-15 chlorinated polyethylene, and 20-25 parts of recycled rubber , Coumarone resin 2~3, naphthenic oil 5~10, carbon black 5~8, zinc oxide 0.5~0.7, stearic acid 0.1~0.3, sulfur 0.4~0.6, accelerator 0.5~0.9, antioxidant 1~ 3. The waterproof coating uses EPDM rubber, reclaimed rubber and chlorinated polyethylene as the film-forming main body, and is supplemented with various modification additives and fillers, so that the waterproof coating has excellent waterproof performance, anti-aging and cold resistance. , has the advantages of convenient construction and low cost, and its composition and construction meet the requirements of national environmental protection standards. The preparation process has simple steps, is convenient for large-scale industrial production, and the storage performance and service life of the obtained waterproof coating are greatly extended. The waterproof coating can be widely used in waterproof construction of buildings, engineering, vertical surfaces and various types of waterproof base surfaces.

The invention discloses a non-solidifying (wriggling) rubber asphalt building waterproof coating and belongs to the field of chemical material building. The coating is prepared by processing the following raw materials: 50-400 parts of regenerated rubber powder, 100-600 parts of 10# asphalt, 50-300 parts of regenerated lubricating grease, 10-200 parts of regenerated flora and fauna grease, 50-300 parts of tertiary-distilled oil, 10-100 parts of polypropylene resin, 10-100 parts of polyamide (PA-12) resin, 10-500 parts of styrene butadiene styrene (SBS), 10-100 parts of coumarone resin, 10-100 parts of carbon 5 resin, 10-100 parts of polypropylene wax, 10-100 parts of paraffin base rubber oil, 10-100 parts of oleamide, 10-100 parts of attapulgite powder, 10-100 parts of smectite and 1 part to 20 parts of silicone oil defoamer. Inspections show that technical indexes of the non-solidifying (wriggling) rubber asphalt building waterproof coating are superior to JC / T864-2008 national material building industry standard of the 'polymer emulsion building waterproof coating', and stability and aging resistance of the coating are greatly improved.

Disclosed therein is a non-curing one-component adhesive waterproof material using scrap rubber and a preparation method thereof in which scrap rubber is mixed with oil, heated and pulverized into size-reduced rubber under mechanical shear stress, and more particularly, to a non-curing one-component adhesive waterproof material using scrap rubber and a preparation method thereof in which scrap rubber is heated to have a reduced elasticity, pulverized into size-reduced rubber under mechanical shear stress, and then mixed with emulsified asphalt, styrene butadiene rubber (SBR), and natural rubber (NR). The present invention includes: 10 to 15 parts by weight of scrap rubber chips; 20 to 25 parts by weight of oil, the scrap rubber chips and the oil being mixed together, heated at 200 to 230 °C and then subjected to size reduction under mechanical shear stress to pulverize the scrap rubber chips into size-reduced rubber; and 29.6 to 40 parts by weight of emulsified asphalt being mixed with the size-reduced rubber. The mixture of the emulsified asphalt and the size-reduced rubber is mixed with 8 to 13 parts by weight of a filler, 1 to 2 parts by weight of a surfactant, and 0.1 to 0.4 part by weight of an anti-ageing agent at a temperature of 90 to 100 °C, and then further mixed with 3 to 6 parts by weight of SBR and 5 to 9 parts by weight of NR for viscosity control.
