Problems solved by technology

In the past, when carbon black was used as a colorant, it was directly added to black powder for mixing without treatment in the rubber product manufacturing process, which would easily cause particles and dullness on the surface of the product, making the product defective. Carbon black is easy to cause dust flying during use, which not only pollutes the environment, but also causes harm to production operators
[0003] Although "functional black pulp" has been developed, it is still not enough to be used in the specific occasions of rubber product manufacturing, and the amount of functional black pulp is relatively small. Its dispersion effect and coloring efficiency in the raw material mixture for rubber product manufacturing still needs to be improved

Embodiment 1

[0022] First mix 36kg carbon black and 57kg plasticizer and then grind it so that the average particle size of carbon black particles is less than 10μm, then add 2kg dispersant HX-A (Qingdao Sainuo New Material Co., Ltd.), 5kg functional liquid carrier, and add to Mix it evenly in a high-speed mixing tank, and cool the resulting mixture to obtain a functional black slurry. Then add 2kg of WACKER fumed silica HDK H20 powder for every 100kg of functional black slurry base material, and mix evenly to obtain a special functional auxiliary material for rubber products containing carbon black particles.

Embodiment 2

[0024] Firstly, 30kg carbon black and 65kg plasticizer are mixed and then ground, so that the average particle size of carbon black particles is less than 10μm, and then 3kg dispersant HX-A (Qingdao Sainuo New Material Co., Ltd.) and 2kg functional liquid carrier are added to the Mix it evenly in a high-speed mixing tank, and cool the resulting mixture to obtain a functional black slurry. Then add 2.5kg of WACKER fumed silica HDK H20 powder for every 100kg of functional black paste base material, and mix evenly to obtain a special functional auxiliary material for rubber products containing carbon black particles.

Embodiment 3

[0026] Firstly, 32kg carbon black and 60kg plasticizer were mixed and then ground, so that the average particle size of carbon black particles was less than 10 μm, and then 5kg of emulsion polymerization dispersant HY (Wuhan Hezhong Biochemical Manufacturing Co., Ltd.) and 3kg of functional liquid carrier were added to the Mix it evenly in a high-speed mixing tank, and cool the resulting mixture to obtain a functional black slurry. Then add 3kg of WACKER fumed silica HDK H20 powder for every 100kg of functional black paste base material, and mix evenly to obtain a special functional auxiliary material for rubber products containing carbon black particles.

Abstract

The invention provides a carbon black particle-containing special functional auxiliary material for a rubber product rubber product, which is prepared by the following steps of: firstly, mixing carbon black with a plasticizer, grinding the mixture to make the average particle size of the carbon black be less than 10 micrometers, then, adding a dispersing agent and a functional liquid carrier to form black slurry base stock, then adding gas-phase silicon dioxide with particle size of 10-40nm into the black slurry base stock according to the dosage of 2.0-5%, dispersing, grinding and mixing to form the special functional auxiliary material. In practical use, the auxiliary material accounts for 1/30-1/10 of the total amount of all components in the production formula of the rubber product. The auxiliary material is excellent in rheological property and high in reinforcement performance; and when the special auxiliary material is used for producing the rubber product, the dosing process is more convenient, the defects of dust flying and environmental pollution are solved, the dispersion effect is high, caking is prevented, and the processed rubber product can simultaneously achieve ideal stretching strength, wear-resisting property, flexing resistance, resilience and permanent deformation performance.

Description

technical field [0001] The invention relates to a polymer material colorant, in particular to a special functional auxiliary material for rubber products containing carbon black particles and its preparation method and application. Background technique [0002] Colorants for polymer materials such as plastic, rubber, and thermoplastic elastomers are indispensable substances in the processing of modern polymers. They can not only beautify the appearance of products, but also have other important functions, such as easy to distinguish colors and improve the weather resistance of products. wait. In the past, when carbon black was used as a colorant, it was directly added to black powder for mixing without treatment in the rubber product manufacturing process, which would easily cause particles and dullness on the surface of the product, making the product defective. Carbon black is easy to cause dust flying during use, which not only pollutes the environment, but also causes h...
