Picture of the manufacturer of the silicone strip
. Two. At the same time, put the silicone rubber sealing strip at high temperature for a period of time (on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, and the surface of the sealing strip will be greased. Precipitated, contaminated with dust, and yellowed (the oil is easy to absorb soil), and the hands are dirty. The physical properties of the silicone rubber sealing strip are unchanged. The sealing ring of the pressure cooker for households is made of silicone rubber, which is made of silicone rubber. High temperature resistance and non-toxic environmental protection performance, the physical properties of the silicone rubber have no obvious changes in the 200 ℃ working environment. 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. Picture 2 of the manufacturer of the silicone strip. At the same time, put it together with the silicone rubber sealing strip at high temperature for a period of time (on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, and the grease on the surface of the sealing strip will precipitate , It is contaminated with dust and yellow (the oil is easy to absorb soil), and the hands are dirty. The physical properties of the silicone rubber sealing strip are unchanged. The pressure cooker sealing ring for household use is made of silicone rubber, which is the use of the resistance of silicone rubber. High temperature and non-toxic environmental protection performance, the physical performance of silicone rubber has no obvious change under the working environment of 200 ℃. If the smell is great, it is not a regular PVC. The sealing strip is a frequently used product, which is made according to a special process and special materials. The function of the sealing strip is to play a sealing role. It is an indispensable part of many products that can effectively protect the performance of utensils. It can be said that it is indispensable and plays a great role. We cannot ignore it. Another point is that it does not absorb water, so it It is also a material that replaces traditional asphalt. It is not precisely because of its water resistance that it will not be saturated under high water pressure. Another point is that it is more environmentally friendly on the entire material and will not cause any damage to the human body. s damage. 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. The rubber material of the silicone strip manufacturer
is classified according to the material. The rubber materials of the automobile sealing strip are compact rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shore A95. EPDM can be combined with steel belt, steel wire braided belt, TPE, Flannel, flocking, PU coating, organic silicon coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction, wear resistance and decoration effects of the car interior and the outside world and itself, and it can also choose to have good ozone resistance Chloroprene rubber (CR) with high performance and good aging resistance. 8℃, Disadvantage: Generally, it has a large expansion in mineral oil and lubricating oil, and it is generally a dark-colored product. Application range: Use temperature range -60-150℃, suitable for high temperature and cold coastal areas with strong ultraviolet radiation and middle and high-rise buildings It is recognized by the domestic door and window industry for its wide application range and excellent comprehensive performance. Disadvantages: poor storage stability, hardening during storage, poor cold resistance, relatively high density, and generally black products. Wooden door, door and window sealing strip product features: self-adhesive wooden door sealing strip is made of EPDM rubber foam, which creates its excellent characteristics, door and window sealing strip characteristics, plastic steel door and window sealing strips are widely used in recent years, a new generation Doors and windows have better corrosion resistance, weather resistance, noise reduction and heat insulation than ordinary door and window sealing strips. The rubber materials of the sealing strips are more resistant to aging, low temperature, moisture, and chemical corrosion, especially ozone aging. Ethylene propylene diene rubber (EPDM). 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.
