化学

The coupling agent KH-570 is a kind of substance with different functional groups, the CH2=C- moiety in the molecule can be cross-linked with the double bond in the quartz resin matrix; the other part of the -O-CH3 functional group can be combined with the filler particles. The surface adsorbs water to form a strong bond. Such an amphoteric substance forms an interfacial layer between the filler example and the resin matrix, and the interface layer can transfer stress, thereby enhancing the bonding strength between the filler example and the resin, improving the performance of the sheet product, and preventing other The medium penetrates into the interface layer, improves the interface state, and is beneficial to the aging resistance, stress resistance and electrical insulation properties of the product. Recommended addition amount ≥ 1.5% of resin.
