Embodiment 1
[0027] 1. Experimental materials
[0028]
[0029] 2. Preparation method:
[0030] (1) Weigh each component according to the proportion, put it into a high-speed kneader and heat it for high-speed stirring. The temperature of the high-speed kneader is controlled at 100-120°C, and the kneading time is 5-10 minutes;
[0031] (2) Put the uniformly stirred raw materials directly into the twin-screw feeder for extrusion, and the heating temperature of each section of the twin-screw feeder is evenly divided from 120-160°C according to the number of heating sections;
[0032] (3) The finished products of extruded materials are packaged and put into storage after being dried.
[0033] The performance test results of the prepared sheath material are shown in Table 1.

Abstract
The invention relates to an environment-friendly antistatic high-flame retardation PVC sheath material. The sheath material comprises the following raw materials by weight: 75 to 100 parts of PVC resin, 35 to 50 parts of a plasticizer a, 5 to 15 parts of a plasticizer b, 4 to 8 parts of a heat stabilizer, 0.1 to 0.2 part of an anti-oxidant, 0.2 to 0.8 part of polyethylene wax, 4 to 10 parts of polyoxyethylene, 0.5 to 1 part of stearate, 5 to 25 parts of a filler, 5 to 25 parts of a fire retardant a, 2 to 8 parts of a fire retardant b, 3 to 10 parts of an antistatic agent a, 0.3 to 2 parts of an antistatic agent and 2 to 8 parts of an antistatic agent c. The sheath material meets all the performance requirements of a 90-DEG C polyvinyl chloride sheath material prescribed in GB8815-2008, shows excellent processing properties and environmental protection performance, accords with ROHS standards, has antistatic performance, surface resistivity of no more than 1.0 * 10<9> omega, a flame retardation function and an oxygen index of more than 32, and can extensively replace overseas import products.
Description
technical field [0001] The invention relates to a PVC cable material and a preparation method thereof, in particular to an environment-friendly antistatic high flame-retardant PVC sheath material and a preparation method thereof. Background technique [0002] Soft PVC cable material is a general-purpose polymer blend material with low price, large dosage and excellent processing performance. As an ideal substitute for rubber materials, it is widely used in chemical industry, communication, electronics and other fields. As we all know, the surface resistivity of soft PVC is as high as 10 14 -10 17 Ω, it is easy to generate static electricity, which can cause fires and explosions in chemical warehouses, coal mines, etc., and failure of electronic components. Usually, in order to optimize the flame retardant properties of PVC materials, antimony trioxide, magnesium hydroxide, aluminum hydroxide, zinc borate and other flame retardants are added; in order to improve the antista...
