Performance test The physical properties of the rubber were tested according to the corresponding national standards. Physicochemical analysis of the physicochemical analysis results of the anti-scorching agent CTP can be found in 1. The small-combination test The results of the small-combination test can be seen from 2. It can be seen from the 2 that within the scope of the test, with the increase of the amount of the anti-scorching agent CT P, the coke of the compound The burning time was prolonged, and the vulcanization rate and physical properties did not change a lot. However, after the amount of the anti-coke agent exceeded 0.3, the needle-like crystal ejecta gradually appeared on the surface of the vulcanized sample with the extension of the parking time. The increase in the amount of coke CT P tends to be serious. The large batching test was based on the results of the small blending test and chose the test formula 2 for the large batching test. The results are shown in 3. From 3, it can be seen that compared with the production formula, the scorch time of the rubber compound of the experimental formula 2 is shortened, and the vulcanization rate and physical properties are changed. Not large, and basically consistent with the results of the small match test. There is no frosting phenomenon in the scope of daily management. The extrusion process calibrated the sidewall composite extrusion process of the large-combination test rubber compound and found that the scorch time of the test compound rubber can meet the production requirements of the sidewall extrusion process, the extrusion process performance is good, and the surface of the semi-finished product part is extruded. There is no frosting phenomenon within the scope of management. The finished product test is to further determine whether the tire bead filler produced using the test formula 2 will produce frosting phenomenon. The test formula 2 and the production formula are used to make a certain type of radial passenger car tire for comparative test of the finished product. 2 and the production of compound rubber compound extrusion side, forming a green tire in the same vulcanizing machine at the same time vulcanization. The results showed that the tires produced using the test formula 2 produced no frosting during parking, and the tires produced using the production formula gradually showed signs of blooming after being parked for about 16 hours, and the degree of blooming increased with time. Shows the contrast between the test tires and the production of finished tires after 96 hours. It can be seen that there is a reflective ring at the bead part of the test tire, and no frosting phenomenon occurs; a clear blooming phenomenon occurs at the bead part of the tire. Concluding remarks on the use of anti-scorching agent CT P in the radial tire bead rubber protective formula, the scorch time of the rubber compound is prolonged, the vulcanization rate and physical properties have little change; when the amount of CT P anti-caustic agent exceeds 0.3, the vulcanization test After spraying for a certain period of time, the surface was frosted; when the amount of CT P was 0 025 parts, the scorch properties and processing performance of the rubber material met the extrusion process production requirements, and the extrusion performance was good. The surface of the semi-finished product was not Frost phenomenon occurs.
