Abstract

The invention discloses a breathable antistatic foam material and a preparation method thereof. The foam material comprises the following raw materials in parts by weight: 100-120 parts of low-density polyethylene, 10-15 parts of glycerin monostearate, 3-8 parts of talcum powder, 3-5 parts of an antistatic agent, 1-3 parts of flame-retardant particles, 3-5 parts of a foaming agent and 1-3 parts of a nucleating agent. The antistatic agent and the flame-retardant particles are prepared in the preparation process, the antistatic agent is prepared by performing esterification reaction on an intermediate 5 and an intermediate 6 to prepare an intermediate 7 and polymerizing the intermediate 7, and the antistatic agent can increase the volume conductivity of the foamed plastic, so that static electricity accumulated in the foamed plastic can be conducted out in time, and theantistatic effect is thus achieved; the flame-retardant particles generate a coke layer on the surface of the material when the foamed plastic is combusted, and the coke layer can insulate oxygen and heat so as to extinguish flames.

Description

technical field [0001] The invention relates to the technical field of foam material preparation, in particular to a breathable and antistatic foam material and a preparation method thereof. Background technique [0002] Items are usually cushioned with foamed plastics during transportation, such as polystyrene, polyethylene, polyurethane and other foamed plastics. For electronic products such as integrated circuits and communication equipment that are easily affected by static electricity, packaging materials need to have antistatic functions. Compared with polystyrene, polyethylene, polyurethane and other materials, polyvinyl chloride is not only cheap, but also has excellent flame retardancy, so the antistatic foam material produced by polyvinyl chloride is very suitable for packaging, transportation and storage of electronic products. [0003] Most of the existing foam materials are prepared from polymers with high volume resistivity, which makes it easy for charges to ...
