preparation example Construction

[0022] Preparation process route of the present invention is:

[0023] 1. Preparation of starch xanthate

[0024] a. Under the condition of mechanical stirring, mix the starch and sodium chloride solution evenly, and the temperature rises to 45°C.

[0025] b. Under mechanical stirring conditions, add an appropriate amount of component A and a little component B and component C to the reaction solution in step a, react at 45°C for 2 to 10 hours, wash and filter, dry, and pulverize. Starch derivatives are produced.

[0026] 2. Component A is a strong alkali solution with a concentration of 15%.

[0027] 3. Component B is a halopropylene oxide.

[0028] 4. Component C is carbon disulfide.

[0029] 5. Use the starch xanthate prepared by the above method as the base material, and then add 18% to 15% reinforcing agent, 0.5% to 1% coupling agent, and 1% to 5% plasticizer to compound the multifunctional rubber Auxiliary.

[0030] 6. Pre-treat the starch sulfonate with a coupling...

Embodiment

[0035] The composition and proportion of the product are as follows:

[0036] 40 parts of natural rubber, 20 parts of butadiene rubber, 40 parts of styrene-butadiene rubber, 8 parts of multifunctional reinforcing agent, 50 parts of carbon black, 4 parts of zinc oxide, 2 parts of stearic acid, 2 parts of antioxidant 4010NA, 1.5 parts of sulfur, Accelerator NOBS 1 part, aromatic hydrocarbon process oil 6 parts.

Abstract

A multi-functional rubber ingredient and a preparation method thereof relate to the chemical engineering accessory ingredient and the preparation method thereof. Starch derivate is prepared by adding a strong alkaline solution component A with 15 percent of concentration, a halogenating epihydrin component B and a carbon bisulfide component C to the mixed solution of starch and sodium chloride, and then the multi-functional rubber ingredient is obtained by adding a strengthening agent, a coupling agent and a plasticizer. Firstly the starch xanthate is prepared, and then 100 parts of prepared starch xanthate are used as base stock, then the multi-functional rubber ingredient is obtained by adding 20 to 25 parts of strengthening agent, 0.1 to 1 part of coupling agent and 3 to 10 parts of plasticizer. Using the method to prepare the multi-functional strengthening agent has the simple technique and high grafting ratio, so the multi-functional strengthening agent has good effect when being used as a tyre rubber ingredient and processing an accelerating agent.

Description

technical field [0001] The invention relates to a chemical auxiliary agent and a preparation method thereof, in particular to a preparation technology and method of a multifunctional rubber auxiliary agent. Background technique [0002] Traditional rubber additives often have a single role. For example, the rubber accelerator has an obvious effect on increasing the vulcanization speed of rubber, but other functions are not obvious. Starch is a renewable ecological material. In recent years, starch modification technology has made great progress, and the methods of modification are also increasing. On the one hand, modified starch has been successfully applied in plastics; on the other hand, the application of modified starch in rubber has already begun. performance. Modified starch is a substance called "engineered biopolymer filler", which is obtained from ordinary starch through various modifications. In recent years, research on starch modification at home and abroad ...
