Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of waterproof paint and its preparation process, and in particular relates to an EPDM waterproof paint capable of forming an organic rubber elastic film and its preparation process. Background technique [0002] Waterproof membranes and waterproof coatings are commonly used waterproof construction materials for buildings. Because waterproof membranes are mechanized in factories, market conditions and factors affecting product quality can be reasonably controlled. In addition, their thickness is uniform, and they have now become waterproof materials. The mainstream product in China, the EPDM waterproof membrane is made of EPDM mixed with an appropriate amount of butyl rubber, vulcanizing agent, etc., and is made by banburying, filtering, pulling, and extruding. Polymer waterproof membrane. Because of its good aging resistance, long service life, good elasticity, excellent tensile properties, good high and lo...
