Description
The present invention relates to chlorosulfonated polyethylene emulsion, particularly be used for producing the emulsion of water soluble chlorosulphonated polyethylene coating.
With chlorine sulphur polyethylene glue is that the chlorosulfonated polyethylene building masonry wall of base-material has good chemical stability and physics, mechanical property, has been well-known.But because chlorine sulphur polyethylene is a molecular-weight average up to about 20,000 superpolymer, makes it emulsification and disperse difficulty bigger, such coating of using of world wide input still is in solvent-borne type and has comparative advantage the stage at present; Solvent based coating not only influences product cost owing to need to consume a large amount of solvents, returns labour protection and has brought difficulty.Therefore, the research of water soluble paint more and more is subject to people's attention recently, but does not obtain satisfied result as yet, as United States Patent (USP) 3245935, though solved water miscible problem, complex process, need at high temperature could film forming to solidify, the use range of coating is restricted.
Solve the problem of water soluble paint, at first will solve the big emulsion problem of gel content of producing.
The objective of the invention is to provide a kind of preparation method simple, raw materials cost is lower, the emulsion gel content is big, at normal temperatures film forming solidified water soluble chlorosulphonated polyethylene emulsifying agent.
The object of the present invention is achieved like this; chlorosulfonated polyethylene emulsion is that base-material adds low viscous mixed organic solvents and makes glue liquor of chlorosulfonated polyethylene through as extraordinary dispersion agent by chlorosulfonated polyethylene glue; and then the adding emulsifying dispersant carries out emulsification; add protective colloid again; mould inhibitor, frostproofer and water; the weight proportion of its each component is: glue liquor of chlorosulfonated polyethylene through: emulsifying dispersant: protective colloid: mould inhibitor: frostproofer: water=100: 5-10: 3-5: 0.5-1: 2-5: 25-65, wherein:
