Problems solved by technology

[0002] With the rise in the price of fluorine materials, the price of fluorine rubber raw rubber has risen sharply, which has led to a substantial increase in the production cost of fluorine rubber compounds. At present, the method of adding a large amount of inorganic fillers is often used to reduce costs, but this method will cause The following disadvantages are caused: 1. The hardness of the material will increase, which cannot meet the customer's requirements for product performance; 2. The tear strength and compression set performance of the material will decrease; 3. The volume cost of the material will increase

Abstract

The invention relates to the technical field of manufacturing of rubber, in particular to a fluorubber formula for rubber plates. A new low-cost and high-activity fluorubber material, namely ultrafine fluorubber micro-powder is adopted as a specific component which is verified by a test for combining with other components in the formula and auxiliaries in types which are related to the specific component which is verified by the test, so that the cost of a product, namely fluorubber gross rubber can be obviously reduced, the performances of the product can still well meet the actual needs, compared with a traditional inorganic filler, the product has obvious advantages and the appearance performance and the processing manufacturability of the mixed rubber are further improved. The fluorubber formula for the rubber plates has the advantages of reducing production cost, improving the performances of the product, beautifying the appearance of the product and enhancing the processing manufacturability.

At present, the method of adding a large amount of inorganic fillers is often used to reduce costs, but this method will reduce the cost. The following disadvantages are caused: 1. The hardness of the material will increase, which cannot meet the customer's requirements for product performance; 2. The tear strength and compression set performance of the material will decrease; 3. The volume cost of the material will increase. For this reason, an economical and applicable fluororubber formula with excellent product performance is needed to meet the needs of actual conditions. Contents of the inven...
