Antistatic non-plasticized PVC composite

Abstract

The invention discloses an antistatic non-plasticized PVC composite, and belongs to the field of polymer processing materials. The antistatic non-plasticized PVC composite is composed of the following components in parts by weight: 100 parts of PVC resin, 1.5-2.5 parts of heat stabilizer, 3.0-7.0 parts of composite antistatic agent, 5-10 parts of impact modifier, 5-10 parts of processing aid, 0.1-0.5 parts of composite antioxidant, 0.5-2.5 parts of lubricant, and 1.0-5.0 parts of composite titanium dioxide. The antistatic non-plasticized PVC composite disclosed by the invention has an efficient and permanent antistatic performance, so that static electricity is not accumulated on the surfaces of PVC products thereof such as pipes and plates, and then the PVC products can be applied to the inflammable, explosive and dustproof fields in which static electricity is not expected to appear; the antistatic non-plasticized PVC composite is excellent in rigidity and toughness.

Description

technical field [0001] An antistatic unplasticized PVC composition belongs to the field of polymer processing materials, and in particular relates to an antistatic unplasticized PVC composition. Background technique [0002] Plastics are widely used in many fields, but they generally have a high electrical resistivity, which is undoubtedly beneficial in the manufacture of cables. However, due to its high insulation performance, it is easy to absorb dust and accumulate charges on its surface to cause static sparks, which limits the application of plastics in some occasions where static charge accumulation is not expected, such as chemical pipes, household decoration panels, experimental Indoor boards and floors, etc. PVC antistatic materials are used in coal mines, chemical industry, electronics industry, industrial packaging and household decorative panels to eliminate static electricity in time, prevent static sparks and electrostatic adsorption of dust, ensure safety, pro...

AI Technical Summary

Problems solved by technology

However, the problems that often arise are: 1. The amount of antistatic agent added is large, the antistatic efficiency is not high, and the mechanical properties drop too much

2. When the antistatic efficiency is high, the antistatic effect is not durable, and it is easy to attenuate the antistatic effect due to scratches during use and prolongation of use time

The antistatic efficiency of using allyl sodium sulfonate alone is not high, and the patent does not formulate and describe the long-term antistatic performance of window profiles

Judging from the current technical situation, the antistatic performance of antistatic materials cannot achieve the effect of adding less and having permanent antistatic effects
