The patterned silicone strip can be used at 100-120℃ for a long time, and it can maintain effective physical properties for a long period of time at 140-150℃. It can withstand high temperature of 230-260℃ in a short time, which is unexpected to urban construction. It can play a time-delay effect; coupled with the use of special formula, EPDM rubber feels similar at -50°C to 150°C, which creates a high-efficiency work performance for installation on the production site. 3. Due to EPDM It has excellent ozone resistance and is also known as 'crack-free rubber'. It is especially used in various urban buildings with different atmospheric indexes and completely exposed to the air. It will show the superiority of its products; 4. Ultraviolet radiation provides environmental protection for residents of high-rise buildings; it can withstand voltages of 60~150KV, corona resistance, electric crack resistance, and arc resistance, which are also very good. 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. Under normal circumstances, EPDM sealing strip
s can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application fields continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization (extruded After the rubber strip is cut according to a certain length, it is put into a vulcanizing tank to vulcanize, and the semi-finished product of the extruded rubber strip is put into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, continuous hot air Several methods such as vulcanization). 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. Four composite sealing strips-Shanghai Shenya Sealing Parts Co., Ltd. has taken the lead in the domestic development and production of composite sealing strips composed of 4 kinds of rubber materials, and a thin layer of protection is coated on the surface of the foam rubber (bubble tube) Layer glue to further increase the service life of the seals. Car sealing strips are classified according to the surface treatment state. After additional treatment, the surface of some sealing strips can be divided into flocking sealing strips; surface coating sealing strips; automotive sealing strips with fabric stickers Special function classification of sealing strips Some sealing strips have electronic intelligence functions, such as anti-pinch sealing strips. 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.

Introduction of patterned silicone rubber car sealing strips The sealing performance is an important indicator of the quality of the entire car, and the car sealing strip product is one of the important parts that determine the pros and cons of this index. It is widely used in the front and rear windshields and doors of cars. , Car windows, engine room, trunk and other body parts, fill the gaps between body parts, have the functions of shock absorption, waterproof, dustproof, sound insulation, decoration, etc., play a maintenance role for the crew and the entire vehicle, and the car is sealed There are many ways to classify the products, usually according to the title of the device part (component), the type of data, the number of composite data, and the work characteristics to stop the classification. The surface of the silicone rubber sealing strip is very flat. When observing its surface, we will also find that its surface has a very uniform foaming density and good resilience performance. The choice of sealing material determines In order to have long-term softness and elasticity, through formula adjustment, the softness of the sealant after drying can be improved to form a good sealing layer between the sheet metal and the rubber strip. The unique high elasticity of butyl rubber ensures the sealing The glue is easy to peel from the metal sheet without contaminating the sheet metal. 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 strips.
