Silicone water retaining strips. Fourth, the aviation industry has also been used in the aviation industry, especially oxygen mask seals and waterproof covers, air-tight seals and shock absorption, etc., these aspects have a great demand for this material Yes, in order to improve the comfort of the car, we also need to pay attention to some details, especially the car sealing strip
. This product is also very useful and can effectively improve the comfort of use. Let us Let's take a look at the functions of car sealing strips. 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. For car sealing strips, we must pay more attention to maintenance and master the correct maintenance method, otherwise the maintenance effect will not be achieved. Let us understand the importance of car sealing strip maintenance. Products The elasticity and compression resistance of the automobile sealing strip are very good, and it also has good resistance to aging, ozone and chemical effects, etc., making the product very strong and durable during use, and installation It is also very convenient. In fact, there are many places in our lives that cannot be separated from this product, because its use effect is very good, friends who don’t know can join me to take a look at the characteristics of EPDM sealing strip. Third, ozone resistance The ozone resistance of the product is very good, and it can be completely exposed to the air to work, so that the superiority of the product is more prominent, and the anti-ultraviolet radiation effect of the EPDM sealing strip is also very good. Yes, but also has excellent physical and mechanical properties, so it is often used to make airplanes, trains, cars, and so on. Silicone sealing strips can also be glued to materials with a smooth surface because of its high shock resistance and waterproof performance. According to the composite structure of rubber materials, automotive sealing strips can be divided into pure rubber sealing strips-composed of a single type of rubber; 2. Composite sealing strip-composed of dense rubber and foam sponge rubber, and often contains a metal skeleton material in the axial direction inside the dense rubber; three composite sealing strip-composed of two types of dense rubber (one of which is light-colored) and sponge rubber The composition usually contains a metal skeleton and reinforcing fibers inside the compact glue. 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. 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. Silicone water retaining strips do not react with any paint or cleaning agents. Customers do not need to worry about the integrity and beauty of doors and windows being damaged. According to the compound structure of the rubber compound, they can be divided into pure rubber sealing strips—consisting of a single type of rubber; Two composite sealing strip-composed of dense rubber and foam sponge rubber, often containing a metal skeleton material in the axial direction inside the dense rubber; three composite sealing strip-consisting of two dense rubbers (one of which is light-colored) and sponge Glue composition, usually contains a metal skeleton and reinforcing fibers inside the dense glue. 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. With the improvement of people's living standards, the improvement of housing conditions and people's high attention to home decoration, more and more people pay attention to the privacy, sound insulation and sealing effect of indoor rooms, 035W/m2K; 5. Fatigue resistance test: imitation The window has been opened and closed 500,000 times without significant changes in shape. 6. Sound insulation test: only IV68 windows with intermediate rubber strip
s, reducing noise by 43 decibels7, IV76 windows with intermediate rubber strips and additional rubber strips, reducing noise by 45 decibels8, Outdoor aging resistance test: It has been more than 20 years, and the performance is maintained intact. The series of products are environmentally friendly products and do not contain CFC harmful substances. 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.
