Problems solved by technology

Generally, one method adopted to achieve the above purpose is to add fillers such as carbon black and graphite in the PVC mixing process. Since carbon black and graphite are materials with easy-to-obtain raw materials, variable prices and excellent electrical conductivity, after The modified PVC material has low volume resistivity and excellent permanent antistatic effect, but adding this material will affect the tensile strength of PVC, and its hardness will also increase greatly, so it is not suitable for PVC In the soft material of coiled material; another method is to coat a layer of surfactant with antistatic effect on the surface of PVC material. Easy to be damaged, its anti-static effect will weaken or even disappear after a certain period of use

Abstract

The invention discloses a preparation method of a carbon-free permanent anti-static PVC (polyvinyl chloride) coiled material, which comprises the following steps: stirring and fusing PVC resin, polyethylene-vinyl alcohol resin, polyaniline, a plasticizer, an anti-aging agent, a stabilizer, a foaming agent and a metal organic framework material at a certain temperature, performing mixing, plasticizing and vulcanizing, and carrying out internal rolling to obtain the coiled material. The PVC coiled material has good mechanical properties and an excellent permanent anti-static effect.

Description

technical field [0001] The invention belongs to the field of engineering material preparation, and in particular relates to a method for preparing a carbon-free permanent antistatic PVC coil. Background technique [0002] Polyvinyl chloride (PVC) has the characteristics of excellent acid and alkali resistance and high mechanical strength. In the actual application process, various additives, such as plasticizers, are added to improve its fracture resistance and cold resistance. It is widely used in various Such products and equipment. In recent years, in many public buildings such as hotels, gymnasiums, and libraries, PVC coiled materials are mostly used as the surface material for laying the floor surface, because this material has moderate hardness, elasticity, and is not Dust, as well as sound insulation, anti-skid and warmth. In the manufacturing workshops of electronic components and electronic equipment, as well as in computer rooms, PVC coils with antistatic function...
