Which is better, rubber or silicone rubber, the classification according to the title of the device part (component) is a common way, which includes the engine room sealing strip, the front and rear windshield sealing strips, the door frame sealing strip, the door sealing strip, and the door glass guide groove sealing. Strips, dust-proof strips on the lower part of the door, internal and external sealing strips of the door and window sill, side window sealing strips, sunroof sealing strips, roof cover sealing strips, trunk (luggage) sealing strips, etc. Installation method: self-contained double-sided tape, directly pasted That's it (the paste surface must be smooth, clean, smooth, and dry). 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. Which is better, rubber strip rubber or silicone rubber, the physical properties of silicone rubber have no obvious change at -50℃. Fifth, see the specific gravity, how many meters can be produced per kilogram, add the PVC sealing strip with heavy calcium, and you can stretch it back and forth several times by hand. There will be a small amount of white powder. The density of PVC sealing strips should be 1,4-1,6. Silicone rubber sealing strips should be filled with nano-silica as a filling and reinforcing effect. The texture is light and the density is 1,1-1. , 25, so the yield rate is 20% higher than that of PVC sealing strips. According to the classification of materials, automobile sealing strips can be divided into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips. In use, many problems need to be paid attention to. You can spray a little when installing rubber sealing strips. Soapy water, this method can make it more convenient for you to install, and in the usual maintenance, avoid direct sunlight, and put it in a cool place, so that the rubber seal can exert more performance, and the service life can be Get extended. The expensive one is fifteen to six thousand yuan per ton, and the cheap one is only 6,000 yuan per ton. The price difference is nearly 10,000 yuan, and the quality difference is very big, which is confusing. Many sealing strip manufacturers claim that their products are in accordance with GB12002-89 , And can issue a test report qualified by an authoritative organization, the classification of sealing strips 1, 2, according to the surface treatment status, some of the sealing strip surface can be divided into flocking type sealing strips after additional treatment; surface coating sealing strips; with fabric Adhesive sealing strip. 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. Which is better, rubber or silicone rubber strips. PVC products contain halogens and heavy metals in stabilizers, which are not conducive to environmental protection. Therefore, developed foreign countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC strips. Low-temperature elasticity and stretchability can reach The temperature at 100MPa is -58. EPDM is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene. The international name: EthyienePropyeneDieneMethyiene is referred to as EPDM. Excellent weather resistance and aging resistance, ozone resistance and chemical corrosion resistance, flexible foam sealing strip, excellent cold and heat resistance (-50℃~+170℃), super elasticity, 200% stretch, good price Lian door and window sealing strip door and window sealing strip classification Plastic steel door and window sealing strip, aluminum alloy door and window sealing strip, wooden door sealing strip, cold storage door sealing strip, grain storage door sealing strip, flame retardant door and window sealing strip, glass sealing strip, automatic revolving door sealing strip, Building door sealing strips, curtain wall sealing strips, etc. New types of thermoplastic elastomers, such as TPO and TPV, are used more and more in automotive sealing strips. According to the type classification, D-type sealing strips are divided into large D-type, small D-type sealing strip, P-type sealing strip and E-type. Sealing strip, but with the development of the automobile industry in recent years, a domestic-made Wonder double-sided adhesive has taken up more and more market shares. It overcomes the shortcomings of 3M adhesive construction that is not resistant to cold, simple construction, and durable adhesiveness. The effect of the previous temperature on the life of the sealing strip! .
In the past few decades, custom sealing strip production has increased because of the use of rubber seal strip suppliers.
