Modification of nano calcium carbonate and its application in PVC industry

Modification of nano calcium carbonate and its application in PVC industry

Plastic filling modification has a long history, its original intention is to reduce costs, such as adding calcium carbonate to PVC hard products, not only can reduce production costs, the appropriate amount of addition can also improve the mechanical properties of PVC hard products. With the focus of material science research turning to nano-materials, the application of nano-calcium carbonate in PVC industry has been widely valued.

Titanate coupling agent, an all-round coupling agent

Titanate coupling agent, an all-round coupling agent

Titanate coupling agent first appeared in the 1970 s. In December 1974, Kenrich Petrochemical Company of the United States reported a new type of coupling agent, which has a good coupling effect on many dry powders. Since then, inorganic filled polyolefin composite materials with titanate coupling agent have been published. In recent years, a series of titanate coupling agents developed by Kenrich companies in the United States have been widely used. Carbon black activated with titanate coupling agent, SiO2, CaCO3, metal oxides added to thermoplastics and rubber can reduce the system viscosity, improve toughness and mechanical properties.

Selection of Titanate Coupling Agent

Selection of Titanate Coupling Agent

Before the selection of coupling agent, should first determine the moisture content of the filler used, according to the wet state and the characteristics of the aforementioned various types of titanate to determine the specific varieties, dry filler should be single alkoxy type, wet filler optional chelate type or single alkoxy pyrophosphate type.

Effect of KH550 silane coupling agent on the structure and dielectric properties of composites

Effect of KH550 silane coupling agent on the structure and dielectric properties of composites

The surface of Ba TiO3 powder was treated with KH550 silane coupling agent, and the Ba2TiO3 / PVDF composite was prepared by solution mixing method and hot pressing process. The morphology of the composites was analyzed by scanning electron microscopy, and it was found that the amount of coupling agent had a great influence on the morphology of the composites;
