Problems solved by technology

[0002] At present, the most commonly used reinforcing agents in the rubber industry are carbon black and white carbon black, but the production cost of these products is high and expensive; followed by reinforcing agents such as silica fume, calcined kaolin and modified clay. The reinforcing effect is far lower than that of carbon black reinforcing agents, and the production cost is slightly lower than that of carbon black, which has a certain market share
However, the functions of the above two types of reinforcing agents are only used as reinforcements or fillers for rubber production, and their sources require a large amount of resources

Embodiment 1

[0019] A composite functional reinforcing agent for rubber production, which is composed of the following raw materials: red mud, regulator and dispersant, and the weight ratio of red mud, regulator and dispersant is 10:1.0:1.0. The adjusting agent is stearic acid and gypsum mixed at a weight ratio of 1:10, and the dispersing agent is calcium phosphate.

[0020] Preparation method: mix all the raw materials evenly, send them into the dryer for drying, the maximum temperature in the dryer does not exceed 750°C, the minimum temperature is not lower than 105°C, the discharge temperature is 120±5°C, and then put the materials into the ultra-fine mill More than 97% of the materials can reach more than 700 mesh.

[0021] The product prepared by embodiment 1 is carried out performance test, and the results are as follows:

[0022] Reinforcement: replace the carbon black in the rubber with the product prepared in Example 1, the replaced carbon black accounts for 1 / 3 of the total carb...

Embodiment 2

[0026] A composite functional reinforcing agent for rubber production, which is composed of the following raw materials: red mud, regulator and dispersant, the weight ratio of red mud, regulator and dispersant is: 8:1.2:1.2. The adjusting agent is stearic acid and gypsum mixed in a weight ratio of 1:9, and the dispersing agent is calcium phosphate.

[0027] Preparation method: Mix all raw materials evenly, send them into the dryer for drying, the maximum temperature in the dryer does not exceed 750°C, the minimum temperature is not lower than 105°C, and the discharge temperature is 130±5°C, and then put the materials into the ultra-fine mill More than 97% of the materials can reach more than 700 mesh.

[0028] Mix all the raw materials evenly and send them into the dryer for drying. The maximum temperature in the desiccant machine should not exceed 750°C, and the output temperature should not be lower than 100°C. Then put the materials into an ultra-fine grinder to about 800 m...

Embodiment 3

[0034] A composite functional reinforcing agent for rubber production, which is composed of the following raw materials: red mud, regulator and dispersant, and the weight ratio of red mud, regulator and dispersant is 12:0.8:0.9. The adjuster is stearic acid and gypsum mixed at a weight ratio of 1:8, and the dispersant is calcium phosphate.

[0035] Preparation method: mix all the raw materials evenly, send them into the dryer for drying, the maximum temperature in the dryer does not exceed 750°C, the minimum temperature is not lower than 105°C, the discharge temperature is 140±5°C, and then put the materials into the ultra-fine mill More than 97% of the materials can reach more than 700 mesh.

[0036] The product prepared in embodiment 3 is subjected to a performance test, and the results are as follows:

[0037] Reinforcement: replace the carbon black in the rubber with the product prepared in Example 3, the replaced carbon black accounts for 1 / 3 of the total carbon black in...

Abstract

Belonging to the field of rubber plastic products, the invention in particular relates to a composite functional reinforcing agent for rubber production and a preparation method thereof. The raw materials include: red mud, a conditioning agent and a dispersing agent. The conditioning agent is stearic acid and gypsum, the dispersing agent is calcium phosphate, and the weight ratio of the red mud, the conditioning agent and the dispersing agent is 8-12:0.8-1.2:0.8-1.2. The composite functional reinforcing agent provided by the invention realizes utilization of waste red mud, has a good reinforcing effect on rubber products, can partially replace carbon black and white carbon black, can completely replace other traditional inorganic filler (like potter's clay, ordinary silicon powder and calcium carbonate, etc) in the rubber formula of rubber products, also can serve as a rubber reinforcing agent and filler. At the same time, the composite functional reinforcing agent also has vulcanization promoting and flame retardant effects, thereby reducing the dosage of carbon black, a vulcanization accelerator, a flame retardant and other expensive raw materials involved in the rubber formula, lowering the production cost of rubber products, and improving the performance of the prepared product.
