Abstract

The invention discloses a preparation method and application of a compound PVC (polyvinyl chloride) antistatic agent. The preparation method of the antistatic agent comprises the following two key steps: 1. preparation of fatty acid monoglyceride: reacting esterification raw materials glycerol and fatty acid at 110-160 DEG C under the action of a catalyst for 1-6 hours; and 2. mixing and compounding the fatty acid monoglyceride and other materials to obtain the finished antistatic agent product. The antistatic agent is compounded from the following materials in percentage by weight: 50-80% of fatty acid monoglyceride, 10-30% of polyoxyethylene fatty acid ester and 10-30% of inorganic metal salt. The PVC antistatic agent is compounded from the two nonionic surfactants and inorganic metal salt. Under the synergic antistatic actions of the three components, the PVC antistatic agent has the characteristics of favorable heat resistance, favorable compatibility with the PVC matrix, lower cost, favorable antistatic property and the like, and has significant application value in PVC antistatic materials.

Description

Technical field: [0001] The invention relates to the field of antistatic agents, in particular to a preparation method and application of a composite PVC antistatic agent. Background technique: [0002] As a general-purpose plastic, polyvinyl chloride has a wide range of uses. Its outstanding advantages are flame retardancy, wear resistance, chemical corrosion resistance, and good gas and water vapor low-pressure permeability. Due to its low price and superior performance, it is widely used in chemical industry, coal, electronics, computer and communication industries, but its surface resistance is generally greater than 10 12 Ω, when the surface resistance of the plastic and its products is greater than 10 10 Ω, materials are prone to generate static electricity during handling, contact, separation, friction and collision, leading to accidents such as fire, explosion and electrical device failure, causing immeasurable losses to human life and property, and hindering its us...
