The role of coupling agent in the processing of plastic tarpaulin

In the processing of plastic tarpaulin products, coupling agents are generally added, which are organic compounds that can enhance the affinity between inorganic fillers and organic polymers. In order to increase the affinity between inorganic substances and organic polymers, the filler must be coupled, and the surface of the filler can be changed from hydrophilic to lipophilic by chemical reaction or physical coating of the inorganic filler. To achieve a close combination with polymers, improve and improve the various properties of tarpaulin products. Among many coupling agents, organosilicon coupling agent is the earliest and most widely used one. The modification of ultra-high molecular weight polyethylene filler is to combine each filler with a coupling agent, then add it to the ultra-commercial molecular pier polyethylene powder, and at the same time add 0.5% antioxidant to stir evenly before use. . Usually, if the surface of the plastic tarpaulin is dirty, it needs to be washed with cold water. Do not use hot water. If there are small mildew spots, you can also use a sponge dipped in a little detergent to brush it.
