Embodiment Construction

[0027] The technical solution of the present invention is described in detail below through specific examples, but the protection scope is not limited thereto. The raw materials used in the present invention can be purchased from the market.

[0028] The invention proposes a polyvinyl chloride / graphene nanocomposite material and a preparation method thereof. The materials used in it include: PVC resin, a plasticizer, a thermal stabilizer and a lubricant.

[0029] The PVC resin is SG-5 type resin, and the requirements for various performance indicators are: apparent density: ≥0.4g / ml; viscosity number: 107-118ml / g; volatile content: ≤0.5%.

[0030] The thermal stabilizer refers to an auxiliary agent that can improve the thermal stability of PVC. Its function is to prevent or inhibit the release of hydrogen chloride during the production process of special materials, and at the same time maintain sufficient thermal stability during the use of the product to prolong the service l...

Abstract

The invention discloses a conductive polyvinyl chloride / graphene nanocomposite with good mechanical property and thermal stability and a preparation method thereof. The conductive polyvinyl chloride / graphene nanocomposite comprises the following raw materials in parts by weight: 100 parts of a polyvinyl chloride resin, 10-50 parts of a plasticizer, 1-10 parts of a thermal stabilizer, 0.1-5 parts of a lubricant and 0-8 parts of graphene. The conductive polyvinyl chloride / graphene nanocomposite solves the problem that the conductivity of the PVC is poor, and remarkably improves the mechanical property and thermal stability of the PVC; the conductivity is up to 1.06*10<-6> S / cm; and the tensile strength is increased by 40.66%.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride composite materials, in particular to a polyvinyl chloride-based conductive polyvinyl chloride / graphene nanocomposite material with good mechanical properties and thermal stability and a preparation method thereof. Background technique [0002] PVC is one of the five most commonly used 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, its performance in professional applications is still insufficient. If PVC is endowed with antistatic properties and conductivity, In the fields of coal mine, petroleum, chemical industry, textile, dangerous goods warehouse, electronics and wireless communication, semiconductor industry and other fields, PVC can replace some antistatic or conductive materials that do not require high mechanical properties and heat resistance, which is helpful for reducing pro...
