Problems solved by technology

But to make the PVC surface resistance reach 10 5 Play the role of static electricity, you need to add 6-12 parts, the impact strength decreases significantly with the increase of carbon black content
As a result, the application of the PVC / carbon black system has been greatly restricted
The PVC / antistatic system mainly adds surface-active antistatic agents. The surface-active antistatic agents in this system belong to the fine chemical industry, and their production pollutes the environment relatively high, and the cost is high, and many products are harmful to the human body.

Abstract

An anti-static anti-impact polymer-composite composition comprises 100 parts of graphene / PVC resin, 5-15 parts of impact modifiers, 3-6 parts of antistatic agents, 2-5 parts of heat stabilizers and 1-3 parts of processing modifiers. A preparation method of graphene / PVC resin includes adding 100-200 ml PVC slurry in a 500ml three-neck round-bottom flask at the room temperature, mechanically stirring to allow PVC particles to suspend in a water phase uniformly, adding in 50-100 ml GO slurry, stirring uniformly, rising the temperature to be 60-90 DEG C, adding in a a reductant according to the mass ratio of 1: 1-10:1 between the reductant and GO, performing stirring reaction for 1-3 hours, reducing the temperature to be lower than 50 DEG C after finishing the reaction, centrifuging or standing, and then drying and screening to obtain functional graphene / PVC resin. The anti-static anti-impact polymer-composite composition has the advantages of reducing fires or explosion caused by accumulation of static electricity caused by friction so as to avoid damage to personal life safety and financial safety.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to an antistatic and impact-resistant polymer composite material composition. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose synthetic resins in the world, and its products are also a general-purpose plastic product with a large output. Although it has a wide range of uses, PVC is easy to accumulate static electricity due to friction during use, which can cause fires. Or explosion, which hinders its use in coal, petroleum, chemical industry, textile, dangerous goods warehouse, electronic and wireless communication, semiconductor industry and other fields. Because pure PVC cannot meet the antistatic requirements in these fields. Therefore, endowing PVC with better antistatic properties can be used in coal mines, petroleum, chemicals, textiles, dangerous goods warehouses, electronics and wireless communications, semiconductor indus...
