High temperature resistant silicone strip manufacturer

by:Kenna     2021-04-15
Manufacturers of high-temperature resistant silicone strips play a key role in electrical cabinets. The skeleton seal is composed of dense rubber, foam rubber and steel wire film. The cabinet seals are mainly used for cabinets, electrical cabinets, and machinery, and are mainly used for fixing Effect and sound insulation, waterproof, dustproof, sealing, recommended temperature range: PVC material 20°F-150°f(-29c-65, a door can not be beautiful, but a sealing strip must be installed to ensure sound insulation and temperature Sealing performance, it can be seen that the sealing strip is necessary for the door. Automotive product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in cars on the market is generally around -25°C, but the weather is relatively harsh In the local environment, the rubber parts on the car cannot withstand the airflow of the cold air, which greatly reduces the product life. The performance of the rubber products used in the car directly affects personal safety. For example, Toyota recalled the sales of auto parts in the past few years. Some of the cars cause serious credit consequences, so all automobile manufacturers need a rubber product with long-term stable performance and sufficient safety. High temperature resistant silica gel manufacturer B, salt bath continuous vulcanization seal: salt bath vulcanization uses nitrous acid The salt bath system of salt has great environmental pollution and has been gradually eliminated. C, according to the cross-sectional shape, it can be divided into solid products (round, square, flat cross-sectional shapes), hollow products, and metal rubber composite products. , EPDM rubber sealing strips are much stronger than PVC strips in terms of sealing elasticity and durability, but due to the need for microwave vulcanization line shaping, processing energy consumption is high, usually more than 20 times that of PVC processing, and the product cannot be reused It is not environmentally friendly and is not an advocated product. Second, high thermal insulation. In the process of use, it has good thermal insulation, which greatly reduces the thermal conductivity. Therefore, the thermal insulation of this product is very good. Yes, it can effectively prevent the loss of temperature. Third, the demand for rubber sealing strips in the automotive industry is very large. Some electronic parts and electrical assemblies are required, such as windshields and car windows The seal of the high-voltage line, the outer skin of the high-voltage line, and the protective cover of the spark plug. It plays a key role in the electrical cabinet. The skeleton seal is composed of dense rubber, foam rubber and steel wire film. The cabinet sealing strip is mainly used For cabinets, electrical cabinets, and machinery, it is mainly for fixing effects and sound insulation, waterproof, dustproof, and sealing. Recommended temperature range: PVC material 20°F-150°f(-29c-65, a door can be not beautiful, but it must be Sealing strips should be installed to ensure sound insulation, temperature and sealing performance. It can be seen that the sealing strips are necessary for the door. 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. The low temperature performance is good, and it can withstand the attack of cold air in a relatively harsh local environment, ensuring good performance, thereby ensuring 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 its Preparation method, its low temperature performance is good, and it can withstand the harsh climate Stay in the cold air to ensure good performance and personal safety. Manufacturers of high temperature resistant silicone strips are used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the body. Its better maintenance ensures safe and comfortable driving. However, few car owners pay attention to its maintenance, but in reality The maintenance of the above is very important, because once it is aging and damaged, it will cause rain leakage in the car, increase the wind noise of the car, and the rain can easily cause the body to rust. We can keep the car sheltered from wind and rain by maintaining it. , Dustproof, heat insulation, sound insulation, and when the body is shaken and distorted, it also plays a role in buffering, absorbing shock and maintaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must always check It is maintained. Humanization 'In the past, the tradition has always paid more attention to materials and workmanship, ignoring the attention to humanization in use. What are the performance advantages of coated seals? 1. Compression deformation test: 50% compression rate at 70°C continues to compress 22 hours, deformation rate≤10%2, compression force test, under 25% compression rate, apply a force of 15N/100mm, compression rate≤10N3, temperature range test: from -40℃ to 90℃, the sealing performance is not obvious Change 4. Heat conduction K value test: K value ≤ 0 at 0℃. According to the classification of material types, automobile sealing strips can be divided into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips. In use, many problems need to be obtained. Our attention is that you can spray a little soapy water when installing the rubber seal. This method can make the installation more convenient, and in the usual maintenance, it is to avoid direct sunlight, and it is placed in a cool place. Only in this way can the rubber sealing strip exert more performance and the service life can be prolonged. Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM rubber, carbon black, and softened rubber. Composition of oil, processing aids, and accelerators
