Abstract

The invention discloses modified wollastonite for a polyvinyl chloride (PVC) cable sheath material capable of resisting 105 DEG C and a preparation method of the modified wollastonite. The modified wollastonite is prepared from the following raw materials in parts by weight: 40 to 60 parts of wollastonite, 10 to 15 parts of polycaprolactone, 5 to 10 parts of aluminum dihydrogen tripolyphosphate, 3 to 6 parts of sperm oil, 1 to 2 parts of sorbitan oleate, 2 to 3 parts of polydiphenylsiloxane, 3 to 5 parts of zinc stannate, 5 to 10 parts of natural zeolite powder, 4 to 7 parts of nano tungsten carbide, 2 to 4 parts of dibromo triphenyl antimony, 1 to 2 parts of dibutyltin dilaurate, 5 to 10 parts of epoxy silkworm chrysalis butyl oleate, 2 to 4 parts of bisphenol A polyoxyethylene ether, 1.5 to 2.5 parts of ethyl p-aminobenzoate and 3.5 to 4.5 parts of auxiliaries. The modified wollastonite has good compatibility with a PVC base material, so that the filling performance of the modified wollastonite in PVC resin is improved so as to enhance a reinforcing effect. Thus, the tensile strength, the electric insulativity, the heat resistance and the like of the PVC cable material are obviously improved. As a result, the modified wollastonite has a wide application prospect.

Description

technical field [0001] The invention relates to a modified wollastonite for 105°C-resistant polyvinyl chloride cable sheath material and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] Wollastonite is a new type of industrial mineral, which belongs to chain metasilicate, and its main component is calcium metasilicate. Due to its low water absorption, low oil absorption, good thermal and chemical stability, high whiteness, and unique powder fibers, wollastonite is widely used in the inorganic materials of polymer-based composite materials such as plastics and rubber. Reinforcing filler. However, the existing wollastonite has poor compatibility with organic high polymers, and it is difficult to uniformly disperse in high polymer base materials. Therefore, it must be modified to some extent. Contents of the invention [0003] The purpose of the present invention is to provide a modified wollastonite for 105...
