Problems solved by technology

On the one hand, PVC plastic has the advantages of good insulation, high strength, and low price. On the other hand, due to its high magnetic susceptibility and good electrical insulation during the friction and peeling process, it is easy to generate static electricity, which can cause explosions or fires. , PVC is easy to generate static electricity, which hinders its application in chemical industry, coal mine, dangerous goods and other fields

Embodiment 1

[0019] Example 1: An antistatic PVC sheet, the components and their contents in the raw materials are shown in Table 1, and the unit of each component in Table 1 is kg. Wherein the lubricant is microcrystalline paraffin, the stabilizer is methyl tin sulfate, and the filler is calcium carbonate.

[0020] The production process of antistatic PVC sheet is as follows, step 1, batching, take each component in the raw material, heat to 85°C, and stir evenly. Step 2, extruding, cooling the material in step 1 to 50°C, feeding it into an extruder for extrusion, controlling the heating temperature of the extruder at 140-150°C, and controlling the plasticizing temperature of the material at 150-180°C. Step 3, calendering, the material extruded by the extruder is calendered with a calender, and the temperature of the calendering roller is controlled between 150-170°C. Step 4, cooling and winding, the PVC sheet calendered by the calender is cooled and rolled to obtain an antistatic PVC sh...

Embodiment 2

[0021] Example 2: An antistatic PVC sheet, the difference from Example 1 is that the components and contents in the raw materials are as shown in Table 1. Wherein the lubricant is calcium stearate, the stabilizer is butyl tin, and the filler is aluminum oxide.

Embodiment 3

[0022] Example 3: An antistatic PVC sheet, the difference from Example 1 is that the components and their contents in the raw materials are as shown in Table 1. The lubricant is glycerol monooleate, the stabilizer is octyltin, and the filler is silicon dioxide.

Abstract

The invention discloses an antistatic PVC (polyvinyl chloride) sheet material, which is prepared from the following raw material ingredients in parts by weight: 60 to 90 parts of polyvinyl chloride, 1to 4 parts of stabilizing agents, 3 to 8 parts of lubricating agents, 1 to 7 parts of fillers, 1 to 5 parts of antistatic agents and 3 to 8 parts of conductive carbon black, wherein the antistatic agent is tribehenin. The antistatic PVC sheet material has the following advantages and effects that the antistatic agent of tribehenin is added into the PVC sheet material raw material; the surface roughness of the PVC sheet material is reduced; the static generated during the PVC sheet material friction is reduced; the static generation is inhibited; secondly, the conductive carbon black in the PVC sheet raw material has a good conductive effect and is dispersed into the PVC sheet material raw material; the conductive performance of the PVC sheet material is improved, so that the electrostaticenergy accumulated in the PVC sheet material can be fast leaked; the static accumulation is inhibited; a good antistatic effect is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to an antistatic PVC sheet. Background technique [0002] PVC is the English abbreviation of polyvinyl chloride. It is an amorphous white powder with a glass transition temperature of 77-90°C. The decrease of the polymerization temperature increases, and it is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging materials, etc. On the one hand, PVC plastic has the advantages of good insulation, high strength, and low price. On the other hand, due to its high magnetic susceptibility and good electrical insulation during the friction and peeling process, it is easy to generate static electricity, which can cause explosions or fires. , PVC is easy to generate static electricity, which hinders its application in chemical industry, coal mine, dangerous goods and ...
