Abstract

The invention relates to an epdm rubber waterproof coating and a preparation method thereof. The total weight portions of dry raw material component of the waterproof coating are: epdm rubber 5-7, chlorinated polyethylene 10-15, reclaimed rubber 20-25, 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 and antioxidant 1-3. The waterproof coating adopts epdm rubber, reclaimed rubber and chlorinated polyethylene as film forming main bodies and also various modified promoter and fillings, which results in that the waterproof coating not only has excellent waterproof, ageing and cold resistance, but also has the advantages of convenient construction and low cost, and the components and construction thereof meet the requirements of national environmental standards. The invention has simple preparation process steps, is convenient to be widely industrially produced, and the store property and life service of the waterproof coating obtained is greatly prolonged. The waterproof coating can be widely applied to the waterproof construction in building, engineering, vertical plane and various waterproof datum planes.

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...
