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 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 in a weight ratio of 1:10, and the dispersing agent is calcium phosphate.

[0020] Preparation method: mix all the raw materials uniformly, send them into the dryer for drying, the highest temperature in the dryer does not exceed 750℃, the lowest temperature is not lower than 105℃, the discharge temperature is 120±5℃, and then the materials are put into superfine grinding It is sufficient that more than 97% of the materials reach more than 700 mesh.

[0021] The performance test of the product prepared in Example 1 is as follows:

[0022] Reinforcement: The product prepared in Example 1 is used to replace the carbon black in the rubber. The substituted carbon black accounts for 1 / 3 of the total carbon black in th...

Embodiment 2

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.
