Silicone corner protectors, these advantages are irreplaceable by other materials such as PVC, and can meet the design requirements for products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements. And the needs of use, the production process of automobile sealing strip
s 1. Extrusion of rubber sealing strips for automobiles is extruded by a cold feed extruder. The extruder head has a single head, a composite (double composite and multiple composite) head and shears. Cutting head, among them, the screw length-to-diameter ratio of the microwave vulcanization extruder is generally 16, and the screw length-to-diameter ratio of the shearing head vulcanization extruder is greater than 20. 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. Silicone angle protection strip material: 1. Made of high-quality EPDM rubber, made by foaming process, 2. The back is made of imported double-sided tape, and the interlayer is grid-shaped glass fiber. Scope of application and installation method: 1. Electrical cabinet sealing strip It is made of EPDM rubber foaming and dense compounding with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). , Contains unique metal fixtures and tongue buckles, strong and durable. At a high temperature of 120℃, the weather resistance of the sealing strip is still good, maintaining elastic properties, and its shape and function are not affected. Thermoplastic EPDM rubber sealing strips are often used in many luxury cars. Type of EPDM sealing strip, what kind of performance does it have in actual use? First of all, it is more flexible, which is very important. Only when this point is reached, can you maintain good performance when you use it, and at the same time, it will not be achieved in long-term use. Deformed. Some developed countries attach great importance to the sealing of the family, even if the balcony is tight and accurate, they do not forget to have sealing strips. There are many types of door and window sealing strips, some are soft rubber sheets, some are foam plastics, and some are chemical fibers. The materials are different. It can also be used in different locations. Secondly, if the door and window sealing strips are in contact with the door in the hot summer season, the color of the door and window will be degraded and yellowed due to the sunlight. This is too bad for the beauty. You must go to a regular store to buy . 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 corner protection strips, car sealing strips are also something that can often be used in cars. Use better quality products in use, so that they can be used for a longer time. Although there are many brands on the market to choose from, they still have to Choose according to your actual situation, because different cars are suitable for different sealing strips, so you can choose the above to compare more. How to use the sealing strip is worth our attention and needs to be remembered, especially in In the hot season, try to use it in a cool place to avoid exposure to the sun. It is divided into self-adhesive type and card slot type. It is used in different doors and windows. It is more convenient and feasible in operation and installation. What is the performance advantage of coated sealing strip? 1. Compression deformation test: Compression rate of 50% at 70℃ 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 ≤ 0.8°C at 0°C, Disadvantage: Generally, it has a large expansion in mineral oil and lubricating oil, and is generally dark-colored products. Scope of application: operating temperature range -60— 150℃ can be applied to high temperature and cold coastal areas with strong ultraviolet radiation and medium and high-rise buildings. With its wide application range and excellent comprehensive performance, it is recognized by the domestic door and window industry. Disadvantages: poor storage stability, hardening during storage, and poor cold resistance Good, relatively dense, generally black products.
