Abstract

A preparation method of polymer modified reclaimed rubber waterproof paint is provided, wherein waste rubber powder is mixed with proper oleic acid, potassium hydroxide, ammonia and polyvinyl alcohol after desulfurization reaction, and made into reclaimed latex; 10 number and 100 number petroleum asphalt mixture, OP emulsifier, water, sodium hydroxide, water glass and polyvinyl alcohol are mixed according to a certain proportion and made into bitumen emulsion; the reclaimed latex and bitumen emulsion are uniformly stirred to become reclaimed adhesive asphalt emulsion; styrene, butyl acrylate and acrylic acid are added into the deionized aqueous solution containing ammonium persulfate, anionic emulsifier and nonionic surfactant, executed with polymerization for 2 hours under the temperature of 100 DEG C, and added with ammonia at last to be neutralized and made into stable emulsion; reclaimed adhesive asphalt emulsion is mixed with phenylacetic acid-acrylate copolymer. The present invention has the advantages of improved adhesive strength and elongation at break.

Description

technical field [0001] The invention relates to a preparation method of a polymer modified regenerated rubber waterproof coating. Background technique [0002] At present, the water-emulsion type reclaimed rubber asphalt waterproof coating replaces the organic solvent with water. It has the advantages of non-toxic, odorless and non-combustible. It is safe and reliable. It can be used for cold construction at room temperature without polluting the environment. It is widely used for construction on slightly damp surface without water accumulation. However, its adhesion to the base surface is low, its tensile strength is low, and its elongation at break is not enough. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a preparation method of polymer modified regenerated rubber waterproof coating. [0004] The technical solution of the present invention is: a preparation method of polymer modified re...
