Problems solved by technology

[0004] However, there are still some problems with silica filled compounds at present: there is a strong interaction between silica particles, and the surface treatment of most mid-priced silica is not perfect, which makes the processing of silica Difficult, not easy to disperse, poor compatibility with rubber commonly used in tread rubber
[0005] At present, most of the white carbon black dispersants used in the market are mainly mixtures of saturated fatty acid zinc salts or derivatives of fatty acids, and zinc salts are easy to cause zinc loss, resulting in environmental pollution. Reducing the zinc content in dispersants has always been a processing aid. key points in drug research

Embodiment 1

[0038] In a 500ml round bottom flask equipped with a stirrer, a thermometer, and a reflux condenser, add 0.1 mol of octadecylamine polyoxyethylene ether with a sum of 60 ethoxy groups of m+n and 0.15 mol of palmitic acid, and heat to 80 Make it all melted at ℃, add 50ml ethanol, then react under reflux until the solution is clear and transparent, change the distillation status to remove the solvent, and cool to below 60℃ to obtain the product.

Embodiment 2～7

[0040] Except for changing the type of fatty amine polyoxyethylene ether, the preparation process of the white carbon black dispersant in Example 1 was repeated. For specific data, see Table 1 below.

[0041] Table 1 Raw materials and products used in Examples 2-7

[0042]

Embodiment 8

[0044] Add 0.2 mol of dodecylamine polyoxyethylene ether with the number of ethoxy groups of m+n and 60, and 0.15 mol of oleic acid into a 500ml round bottom flask reactor equipped with a stirrer, a thermometer and a reflux condenser. The whole is melted at 100°C, 50ml of toluene is added, and then the solution is reacted under reflux until the solution is clear and transparent. The solvent is changed to the distillation state and cooled to below 80°C to obtain the product.

Abstract

The invention relates to a white carbon black dispersant. The dispersant is prepared through reaction of organic amine substances and organic acid substances, the dispersant can be loaded in different carriers The white carbon black dispersant has a simple preparation method, can raise dispersion of white carbon black in rubber effectively, and raises the processing properties and various physical properties of the rubber.

Description

Technical field [0001] The invention relates to a white carbon black dispersant for the rubber industry, which is used to improve the white carbon black dispersing ability during the mixing process of rubber and rubber composition. Background technique [0002] With the development of society, consumers’ awareness of safety and environmental protection has increased, and higher demands have been placed on the performance of tires. This inevitably requires tire manufacturers to continuously optimize and reduce tires’ wet grip and rolling resistance. improve. [0003] As an important reinforcing agent in rubber materials, silica has been rapidly developed in recent years, especially its use as a reinforcing filler for tire tread rubber has attracted special attention. Since the surface of white carbon black has a large number of hydroxyl groups, when white carbon black is used in the tread, these hydroxyl groups can interact with the water molecules of the road surface, which is con...
