Preparation method and processing equipment of bio-based modified low-heat-generation reinforcing agent

Abstract

The invention relates to a preparation method of a bio-based modified low-heat-generation reinforcing agent, which comprises the following steps: S1, pounding a non-metallic mineral material, desanding, grinding, adding the non-metallic mineral material into a first stirring kettle, adding sodium chloride and a calcium carbonate solution into the first stirring kettle, stirring, heating, adding a silane coupling agent Si-69 and stearic acid, mixing, continuously stirring at a high speed and heating; adding zinc oxide and phenolic resin to obtain modified kaolin; S2, putting the modified biomass, lignin, petroleum resin and urotropine into a second stirring kettle, and stirring and mixing to obtain the bio-based modified low-heat-generation reinforcing agent. The invention further provides equipment used in the method. The reinforcing agent disclosed by the invention is high in surface activity, easy to mix into a rubber sizing material, good in processing technology, capable of effectively reducing compression heat generation of the sizing material, improving the bonding effect of a tire body and a belt ply cord fabric sizing material with a steel wire, improving physical and mechanical properties such as aging resistance of the sizing material and the like, and capable of partially replacing carbon black and white carbon black.

Description

technical field [0001] The invention relates to the technical field of rubber reinforcing fillers, in particular to a preparation method and processing equipment of a bio-based modified low heat generation reinforcing agent. Background technique [0002] At present, the reinforcing agents for rubber are mainly carbon black and white carbon black. The lignin and bio-based modified low-heat reinforcing agent is a combination of lignin and bio-based modified materials and functional organic materials with modified It is compounded and mixed with non-metallic mineral nano-materials such as kaolin and imonite. It can replace about 30% of carbon black and white carbon black, reduces the amount of carbon black, and saves the petroleum energy used in the production of carbon black. Used together with carbon black and white carbon black in the rubber compound to achieve a synergistic effect. Using this reinforcing agent in the tire rubber compound can not only maintain the original ...

Problems solved by technology

This modification method has the disadvantages of high production cost and low quality, especially when the produced product is used in the production of rubber field, it is difficult to eat powder, and the quality of rubber products is low. When used for natural rubber and various synthetic rubber, In terms of reinforcement, it is not as good as ordinary fillers such as calcium carbonate, clay, etc. The comprehensive performance of the rubber material is not ideal, and it has a certain impact on vulcanization. Adding a large amount will affect the performance of the product, so it cannot be widely used in various rubber products.

[0004] Another important factor for the above problems is that when the materials are mixed, the contact area between the materials becomes smaller due to the defect of the mixing equipment, so that high-quality mixing cannot be achieved, which affects the non-metallic mineral materials. modification effect
