Problems solved by technology

A large amount of high-salt organic wastewater will be produced in the production process of silane coupling agent, which will seriously pollute the environment, and the price is relatively expensive
Fatty acid zinc soaps and fatty acid esters are only used as dispersions to physically modify white carbon black, but the effect is not obvious, and the use of silane coupling agents and dispersants is cumbersome.

Embodiment 1

[0045] The formula of the white carbon black dispersant for rubber of the present invention is: 60 parts of stearic acid amide, 25 parts of pentaerythritol tetraester stearate, and 15 parts of plasticizer A (saturated and unsaturated mixed fatty acid zinc soap).

[0046] The preparation method is as follows: Stir and melt fatty acid soap salt and fatty acid ester at 100°C, then add fatty acid amide or fatty acid amine at 115°C and stir to melt, pour out and cool to form tablets or melt and granulate to obtain new white rubber for rubber Carbon black dispersant. The preparation process flow chart is shown in Figure 5 .

Embodiment 2

[0048] The formulation of the white carbon black dispersant for rubber of the present invention is: 50 parts of stearic acid amide, 30 parts of pentaerythritol tetraester stearate, and 20 parts of plasticizer A (saturated and unsaturated mixed fatty acid zinc soap). The preparation method is the same as in Example 1.

Embodiment 3

[0050] The formulation of the white carbon black dispersant for rubber of the present invention is: 55 parts of stearic acid amide, 25 parts of pentaerythritol tetraester stearate, and 15 parts of plasticizer A (saturated and unsaturated mixed fatty acid zinc soap). The preparation method is the same as in Example 1.

Abstract

The invention discloses a white carbon black dispersant for rubber, which is characterized in that it consists of the following raw materials in parts by weight: 30-70 parts of fatty acid amine / amide, 10-30 parts of fatty acid ester, and 0-30 parts of fatty acid soap salt . The invention also discloses its preparation method. The preparation method is simple and fast. The obtained white carbon black dispersant has multiple functions of dispersion, lubrication and chemical modification, which can improve the processing safety performance, physical and mechanical properties and vulcanization speed of rubber compounds. The effect is remarkable.

Description

technical field [0001] The invention relates to a white carbon black dispersant for rubber and a preparation method thereof, belonging to the technical field of fine chemicals. Background technique [0002] In order to improve the mechanical strength, wear resistance and wet skid resistance of the tire, it is necessary to add a large amount of filling and reinforcing agent silica to the rubber. Due to the presence of a large number of silanol groups on the surface of silica, these groups are easy to aggregate and agglomerate, and it is difficult to disperse uniformly during tire processing, and the Mooney viscosity of the compound is easy to rebound, thereby affecting the mechanical properties. Therefore, it has become a major problem in today's tire production and processing to disperse silica well and evenly in rubber and improve the fluidity of the rubber compound. [0003] In order to disperse silica in rubber, silane coupling agent is generally added, and the effect is...
