Extrusion process of silicone foam strip

by:Kenna     2021-07-13
During the extrusion process of silicone foam strip, the function of the sealing strip is to improve the air tightness and prevent wind and rain from entering the car. In order to avoid the occurrence of the above, the sealing strip must be regularly maintained. 5. Due to the excellent physical machinery Performance, so it is often used in the manufacture of waterproof parts such as airplanes, cars, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-insulating windows and diving products, high-pressure steam hoses, tunnels, viaduct joints, etc. And other industrial and agricultural sealing parts. 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. The extrusion process of silicone foam strips is of course, rubber sealing strips can also be used in medical applications. No matter what kind of field the product is applied in, the use effect is very good. It can meet everyone's needs and bring you With great help, the effect of the rubber sealing strip is very ideal, and the color and specifications can be customized according to the needs of customers. The packaging requirements are also carried out by the needs of the installation customers, so it is possible to choose this product Brings great convenience to everyone. This technology is recognized by the world as a good process method for producing extruded products. The characteristic of microwave heating is that heat is directly generated in the object to be heated, instead of being input from the outside as usual. This not only generates heat quickly, but also distributes it uniformly, which is beneficial Improve product quality and greatly shorten the heating time. Hot air vulcanization sealing strip: Hot air sulfur has developed to strong wind type vulcanization, that is, high temperature, high speed hot air vulcanization (Tmax: 450°C and Vmax: 60m/s) is also used. The effect of flame pretreatment can be achieved, and the safety is greatly improved. Third, the structure of good water absorption is very characteristic. It adopts the structure of independent bubbles. Therefore, the water absorption performance of the product is very good, which will achieve the effect of moisture resistance. This product has many advantages. Not only is the transparent effect good, but the appearance of the product is also very smooth. It is a very soft and elastic product. Moreover, this product has no odor and has good high temperature and low temperature resistance. The use of this product is not prone to aging and deformation. Then, what are the characteristics and uses of rubber 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.

Ensure personal safety. The extrusion process of silicone foam strip is also called fire-resistant silicone sealing strip and fire-resistant self-extinguishing silicone sealing strip. It is known for its good flame-retardant and self-extinguishing performance. The main process is to first use high-quality silicone raw materials through a large extruder. A molded silicone strip is then made through high room temperature vulcanization and drying. Compared with ordinary silicone strips, the difference between high temperature and flame retardant silicone strips is that it needs to add flame retardant powder to the formula. The silicone strips that come out have super flame-retardant and fire-resistant properties, and play a certain role in safety protection in the sealing of electronic appliances. Therefore, many people also call them fire-resistant sealing strips. High-quality products will improve the overall style and performance of the door in terms of appearance, internal quality, or later use. Wrapped seals are a modern development trend. Where can wrap seals be used? Wooden windows, aluminum-clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Copper doors, cast aluminum doors, plastic steel doors and windows, etc. There is no obvious change in the physical properties of silicone rubber at -50°C. Fifth, depending on the specific gravity, how many meters can be produced per kilogram, the PVC sealing strip with heavy calcium added, you can stretch it back and forth several times by hand, and a small amount of white powder will appear on the surface. The density of PVC sealing strips should be 1,4-1,6. Silicone rubber sealing strips should be filled with nano-scale silica as a filling and reinforcing effect. The texture is light and the density ratio is between 1,1-1,25. The material rate is 20% higher than that of PVC sealing strips. 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.
