Silicone strip light guide

by:Kenna     2021-06-10
Silicone strips guide light. People's perfection of doors and windows can be said to symbolize the perfection of human beings. It will protect your voice and ears, make life more comfortable, and save energy. There is a goal: to promote the development of 'global environmental protection doors and windowsIt may contribute to the world's energy and environmental protection. The air cabinet sealing strip is made of good elasticity and resistance to compression deformation, aging, ozone, and chemical effects. It has a wide operating temperature range (-40℃~+120℃), ethylene-propylene -Diene rubber (EPDM) composite rubber is foamed and dense, with unique metal clamps and tongue buckles, which is durable. 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. Among the light guide silicone strips, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be the same and appropriate in size. The force contacts the glass from both sides of the car window glass. Regularly check whether there are cracks and whether there is any breakage. If you find that the sealing strip is broken, you can first find an adhesive to repair it. Here is the bonding The agent is specially used for bonding, so that it is not difficult to repair the cracks. 2. At the same time, put the silicone rubber sealing strip at high temperature for a period of time (placed on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, the grease on the surface of the sealing strip will be deposited, contaminated with dust, and Yellowing (oil is easy to absorb soil) seepage, dirty hands; the physical properties of silicone rubber sealing strips have no change, the pressure cooker sealing ring for household use is silicone rubber, which uses the high temperature resistance, non-toxic and environmental protection of silicone rubber Performance: There is no obvious change in physical properties of silicone rubber in a working environment of 200°C. A small number of door and window companies in low-level price competition are still in use. Medium and high-end PVC strips can meet the standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they are often used in the manufacture of airplanes and cars. , Trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties. 2. The semi-finished rubber sealing strip extruded by the vulcanization cold feed extruder is vulcanized by continuous vulcanization process. The vulcanization methods include microwave vulcanization, shear head vulcanization, salt bath vulcanization and fluidized bed vulcanization (also called vulcanization bed vulcanization, heating medium The technical realization element: 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 and can withstand the attack of cold air in a relatively harsh local environment. Good performance to ensure personal safety. Technical realization elements: 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 and can withstand cold air in a harsh climate. Invasion, to ensure good performance, thereby ensuring personal safety. Silicone strip light guide material: 1. Made of high-quality EPDM rubber, made by foaming process, 2. Imported double-sided tape is used on the back, and the interlayer is grid-shaped glass fiber. Scope of application and installation method: 1. The electrical cabinet sealing strip is made of EPDM with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide operating temperature range (-40℃~+120℃) Rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue-shaped buckles, which are strong and durable. Car sealing strips can be classified into solid core products according to the cross-sectional shape (round, square, flat cross-sectional shape) ), hollow products and metal rubber composite products, and secondly, heat aging resistance EPDM sealing strips have been tested many times before production. From the experiments, it can be seen that the products can continue to work in high temperature environments , And there will be no aging phenomenon, so many companies improve work efficiency through the use of products, so as to obtain more profits. Since the silicone sealing strip is mainly produced by using silicone rubber materials, it is better than Sealing strips of other materials have better sealing performance, and can also be used in some high-temperature environments. They have excellent weather resistance and can effectively resist the invasion of natural factors. Even if they are used for a long time, they will not be damaged by aging. , Generally, the back of the silicone sealing strip is provided with an explanation, so it can be effectively bonded with other materials without using any adhesive, and it also has a good sealing performance, whether it is in It will not fall off as long as it is used in a high temperature environment, so it has become the first choice for sealing materials.
