Description
Technical field
The present invention relates to black slurry technical field, and in particular to a kind of cable special environment protection black slurry and preparation method thereof.
Background technology
Plastic cement, rubber, the colouring agent of thermoplastic elastomer (TPE) Polymer material are can not in modern polymer process
Or scarce material, not only also it can easily differentiate with some other effects, such as color with beautify product outward appearance, improve product
Weatherability, heat resistance etc., because carbon black not only has excellent tinctorial property, and there is strengthening action to rubber, carbon black by
Gradually turn into the indispensable raw material of rubber industry.
Prior art, most of black slurry are made up of carbon black, plasticizer, dispersant, functional vector, Publication No.
CN101514264A Chinese invention patent《Feature black wash and its manufacture method》A kind of feature black wash is disclosed, is formulated and is
25~40Wt% of carbon black, 55~70Wt% of plasticizer, 2~5Wt% of dispersant, 2~5Wt% of functional liquid carrier.The formula
Plasticizer loading it is more, although reducing cost, its tinctorial yield and dispersiveness are poor.
