Antistatic PVC (polyvinyl chloride) modified material and preparation method thereof

Abstract

The invention relates to the technical field of PVC (polyvinyl chloride) materials, particularly an antistatic PVC modified material and a preparation method thereof. The antistatic PVC modified material is prepared from the following raw materials in parts by weight: 80-120 parts of PVC resin, 35-55 parts of plasticizer, 10-15 parts of filler, 2-3 parts of heat stabilizer, 2-4 parts of antistatic agent and 0.6-1.0 part of lubricant. By adopting the raw materials and strictly controlling the weight parts of the raw materials, all the properties of the prepared antistatic PVC modified material exceed the national standard; and the antistatic PVC modified material has the advantages of favorable effect, environment friendliness, favorable temperature and weather resistance, high strength, excellent impact resistance, favorable flame-retardant effect, favorable processability and excellent comprehensive properties.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to an antistatic PVC modified material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has the advantages of light weight, high strength, insulation, flame retardancy, corrosion resistance, excellent comprehensive performance, low price and wide source of raw materials; but also There are the following disadvantages: 1. The toughness is poor, and it is easy to be brittle when impacted, so it cannot be used as a structural material. In addition, the brittleness of polyvinyl chloride is greatly affected by temperature. The lower limit of general PVC products is -15°C. The lower limit of use of PVC is -30°C; 2. Poor thermal stability, it begins to decompose HCl at 100°C, and decomposes more rapidly when it is higher than 150°C, and the melting temperat...

[0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has light weight, high strength, insulation, flame retardancy, corrosion resistance, It has the advantages of excellent comprehensive performance, low price and wide source of raw materials; but it also has the following disadvantages: 1. Poor toughness, easy to be brittle when impacted, so it cannot be used as a structural material. In addition, the brittleness of polyvinyl chloride is greatly affected by temperature. Large, the lower limit of general PVC products is -15°C, and the lower limit of soft PVC is -30°C; 2. Poor thermal stability, it begins to decompose HCl at 100°C, and decomposes more rapidly when it is higher than 150°C. The melting temperature of PVC is about 210°C; 3. The viscosity of PVC is extremely high and its fluidity is extremely poor, which limits its use to a certain extent.

[0005] The above-mentioned existing PVC materials have poor antistatic performance, which limits the application of PVC materials in the field of electronic product packaging. Therefore, it is particularly important to develop an antistatic PVC material.
