The better-selling silicone strips. In some developed countries, family sealing is attached great importance. Even if the balcony is tight and accurate, they do not forget to have sealing strip
s. There are many types of door and window sealing strips, some are soft rubber sheets, some are foam plastics, and Some are made of chemical fibers, and different materials will be used in different locations. Secondly, if the weather is hot in summer, the door and window sealing strips will contact the door due to the sun's rays, which will cause color degradation and yellowing, which will affect the appearance. Go to a regular store to buy. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. The better-selling silicone strips are expensive at 15,000 to 6,000 yuan per ton, and the cheaper one is only 6,000 yuan per ton. The price difference is nearly 10,000 yuan, and the quality difference is very big, which is confusing. Many sealing strip manufacturer
s call their products. It implements the GB12002-89 standard, and can issue a test report qualified by an authoritative organization. The sealing strips are classified 1, 2, according to the surface treatment state, and the surface of some sealing strips can be divided into flocking sealing strips after additional treatment; surface coating Layer sealing strip; there are fabric patch sealing strips. This technology is recognized by the world as a good process for producing extruded products. The characteristic of microwave heating is that heat is directly generated in the object to be heated, instead of being input from the outside as usual. This not only generates heat quickly, but also distributes it uniformly, which is beneficial Improve product quality and greatly shorten the heating time. Hot air vulcanization sealing strip: Hot air vulcanization has developed to strong wind type vulcanization, that is, high temperature, high-speed hot air vulcanization (Tmax: 450°C and Vmax: 60m/s) is also used. The effect of flame pretreatment can be achieved, and the safety is greatly improved. For this reason, the GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated very early to standardize the production and inspection of sealing strips. However, the quality and price of rubber and plastic sealing strips for doors and windows in the building materials market are very confusing. , Four-composite sealing strip-Our company takes the lead in the domestic development and production of a composite sealing strip composed of 4 kinds of rubber materials, and a thin protective layer of glue is coated on the surface of the foam rubber (bubble tube). Thereby further improving the service life of the seal. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety.

Ensure personal safety. The better-selling silicone rubber car sealing strips can be classified into weather sealing strips (WEATHERSTRIP) and general sealing strips (SEALING) according to their sealing characteristics. Among them, weather sealing strips have a hollow sponge bubble tube, which has better temperature and humidity retention. The function includes the following items in the usual maintenance process. First, the detergent must be cleaned. After the cleaning is not done, it is also necessary to apply a layer of protective agent to prevent aging and prevent dust. Second, after the sealing strip is damaged, it is easy for rainwater to enter the car. This phenomenon will cause damage to the car body, and it is easy to cause the car body to rust. From this point, we can see that the sealing strip is like this. Although the product is a small object, it is also an indispensable part for the car. When the car sealing strip is intact, it can effectively reduce the wind noise caused by high-speed driving, and it also improves the car’s air. Tightness and dust-proof effect, it can be seen that regular maintenance of the sealing strip is very important. The heat resistance and cold resistance, insulation and conductivity, as well as flame retardancy are very good. It can be used at 100-120℃ for a long time, and it can remain effective for a long period of time at 140-150℃. Its physical properties can withstand high temperatures of 230-260℃ in a short period of time, and it can delay the effect of sudden accidents in urban buildings; coupled with the use of special formulas, EPDM rubber feels similar at -50℃ to 150℃ , This has created a high-efficiency work performance for the production site installation. Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM, carbon black, softening oil, processing aids, and accelerators. 2. The automobile product rubber according to claim 1, wherein the automobile product rubber is calculated by weight ratio, the EPDM rubber is 100, the carbon black is 90, the softening oil is 20, and the processing aid is 15 , The accelerator is 5. 3. A preparation method of automobile product rubber formula, which is characterized in that it comprises the following steps: step one, put the EPDM rubber into the internal mixer, and the mixing temperature is controlled below 80 ℃ Mixing for 2 minutes; step two, add carbon black, softening oil, and processing aids in sequence, and mix for 10 minutes; step three, pour the material to extrude a rubber sheet with a thickness of about 8mm and a width of about 400mm;
