Embodiment 1

[0026] The formula is: PVC paste resin: 45%, (weight, the same below) plasticizer: 30%, zinc stearate stabilizer: 2.8%, and the balance is heavy calcium carbonate filler. Conductive mica powder: 9%, silver nanowire powder: 0.2%, titanate coupling agent: 0.01%, and a sample film was obtained according to the above preparation method. After drying for 48 hours, the surface resistivity of the sample film was tested to be 10 6 ~10 7 Ω, in line with antistatic requirements.

Embodiment 2

[0028] The formula is: PVC paste resin: 50%, (weight, the same below) plasticizer: 25%, barium stearate or calcium stearate stabilizer: 1.2%, conductive mica powder: 12%, silver nanowire powder : 0.4%, titanate coupling agent: 0.02%, and the remainder is a heavy calcium carbonate filler. The same method as in Example 1 measures the surface resistivity of this film to be close to 10 7 Ω.

Abstract

This invention relates to a type of anti-static polychlorovinyl composite material and the method. Compounding include PVC resin, lasticizer, stabilizer, packing matetial. The feature is the formula also includes electric conductive mica, coupling agent of organic titanate and a little of nanometer sliver line power. It uses electric conductive mica and sliver line power which has been processed by coupling agent of organic titanate as the conductive packing material, surface resistivity reach to 106-107omega after film coating. The coupling agent of organic titanate disperses sliver line power well-distributed in PVC resin, solves the problem of agglomeration of nanometer power efficaciously.

Description

technical field [0001] The invention belongs to functional polymer materials, and mainly relates to a novel antistatic polyvinyl chloride composite material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the most used resin varieties in the plastic industry in the world, and its resistance is as high as 10 15 Ω or higher. Good electrical insulation properties lead to the accumulation of electrostatic charge in some occasions, which will cause losses or even disasters. For example, when plastic conveyor belts or plastic pipes transport flammable and explosive materials, electrostatic discharges are often generated due to the flow of materials. or explosion; in precision instrument control rooms and large computer rooms, due to plastic static electricity, errors in instruments and meters are often caused; plastic films are contaminated by dust due to static electricity during processing, resulting in poor heat-sealing fastne...
