example 1

[0031] 1) Surface modification and dispersion of carbon black

[0032] Add carbon black, desalinated water accounting for 50% of the total water, emulsifying dispersant, and surface modifier in sequence in proportion, and heat up to 80-90°C. During the stirring process, slowly add potassium hydroxide solution (dissolve hydrogen with 50% desalinated water) Potassium oxide obtains), after adding potassium hydroxide solution, continue to stir for 30 minutes.

[0033] Component ratio: 400 parts of desalted water, 100 parts of carbon black (N330), 8 parts of surface modifier {isopropyl-tri(ethoxy)silane}, 4 parts of emulsifying dispersant (fatty acid), 1 part of potassium hydroxide share.

[0034] The resulting carbon black dispersion: dry matter 21%, pH 9.8, stability (floating / sedimentation after standing for 24 hours) 0.6%.

[0035] 2) Mixing of carbon black dispersion-rubber emulsion / solution and separation of blends

[0036] Mix the rubber emulsion, carbon black dispersion ...

example 2

[0041] During the dispersion process of carbon black, change N330 to N110, and other formulations and conditions are as in Example 1. The carbon black dispersion is mixed with the styrene-butadiene mortar for coagulation and drying, and the performance of the obtained powdered styrene-butadiene carbon black masterbatch product is still within the control range.

example 3

[0043] The fatty acid in example 1 is changed into abietic acid, and other conditions are unchanged and carry out emulsification dispersion, can obtain the carbon black dispersion liquid that satisfies the requirement equally: dry matter is 20%, pH value 10.1, stability (after leaving standstill 24 hours, floating / sedimentation) 0.5%. The carbon black dispersion is mixed with the styrene-butadiene mortar, and coagulated and dried, and the index of the obtained product still meets the requirements.

Abstract

The invention relates to the production method butylbenzene carbon black masterbatch comprising, using butadiene styrene rubber emulsion as raw material, blending with carbon black dispersion, then condensation insulating, scouring, dewatering, drying, sieving thus obtaining butylbenzene carbon black masterbatch.

Description

[0001] Field: [0002] The invention belongs to a preparation method of a masterbatch, in particular to a production method of powdered styrene-butadiene carbon black masterbatch. Background technique: [0003] Masterbatch refers to a kind of rubber mixed with carbon black and other fillers in rubber. It can be a pre-mixed rubber semi-finished product or a final rubber formula. It can solve the problem of carbon black pollution and loss during rubber mixing. [0004] The preparation of masterbatch is divided into dry method and wet method. Dry masterbatch is to use conventional mixing equipment to mix solid rubber and carbon black and other fillers together with strong mechanical shear force. Its process is simple and easy to operate, but its energy consumption is high, so its application is greatly limited. The advantages of masterbatch produced by wet method are mainly reflected in: good dispersion of carbon black, good mixing effect with other matching materials, energy ...
