[Abstract]:
Vehicle sealant
In the -40 ℃ low temperature resistance test, the sealing strip does not become hard and does not become brittle. It still maintains softness and good adhesion of the rubber strip, showing excellent cold resistance. At 120 ℃, the weather resistance of the seal is still good, maintaining elastic properties, and the shape and function are not affected.
The choice of the sealing strip material determines its permanent softness and elasticity. Through the adjustment of the formula, the softness of the sealant after drying is improved, so that it can be used in sheet metal and rubber strips.
A good seal layer is formed between them, and the unique high elasticity of butyl rubber ensures that the sealant is easily peeled off from the metal sheet metal without polluting the sheet metal.
Sealing strips for automobiles are mainly made of EPDM rubber foam with good elasticity, compression resistance, aging resistance, ozone, chemical action, and a wide use temperature range (-40 ℃ ~ + 120 ℃) It is compounded with compact and contains unique metal clamps and tongue-shaped buckles. It is durable and easy to install.
For the material of automobile sealing strips, natural rubber was mostly used in the early stage. Later, with the continuous development of technology, synthetic ethylene, propylene rubber and nitrile rubber quickly became the main material of the sealing strip. High requirements: good weather resistance, abrasion resistance, low water absorption rate, small residual deformation, good flexibility even at low temperature, and non-polluting properties.
 Automobile sealing strips are required by a large number of parts of the entire car body. The car body has the widest sealing area, the most different sealing states, and the difficulty of sealing is relatively high. Therefore, the compression method, bending method, and composite method are commonly used to achieve the sealing of the car body. Three ways to achieve the overall sealing of the car body.
