Abstract

The invention discloses a soaked-plastic product with flame retardation and antistatic performance and a preparation method thereof. The soaked-plastic product comprises the following components: 50 to 100 parts of a PVC resin, 20 to 100 parts of a plasticizer, 1 to 15 parts of an antistatic agent, 0.5 to 15 parts of a dispersing agent and 0.2 to 10 parts of a stabilizing agent. The preparation method comprises the following steps: preparing a plastic dipping liquid from the above-mentioned components; preheating a mold to a temperature of 120 to 250 DEG C, then immersing the die in the plastic dipping liquid and taking the mold out in 1 to 120 s; and plasticizing the mold attached with plastic at a temperature of 200 to 550 DEG C for 2 to 80 s, taking the mold out for cooling for 5 to 60 s and carrying out demolding so as to obtain the soaked-plastic product with flame retardation and antistatic performance. The soaked-plastic product prepared by using the method has surface resistivity of 105 to 109 omega and good antistatic performance and flame retardation, and vertical combustion of the product reaches standards of the UL94-V0 grade.

Description

technical field [0001] The invention relates to a polyvinyl chloride molded product and a preparation method thereof, in particular to a flame-retardant and antistatic polyvinyl chloride dip-molded product and a preparation method thereof. Such products can be widely used in various types of appliances that require flame retardancy and static elimination, and various products that require electrostatic protection, such as aerospace optical fiber modules, circuit devices, static conductive devices, high-speed connectors, communication optical fiber industries, laser ferrules, Protection of micro-coaxial and optical cable devices, etc. Background technique [0002] PVC is a general-purpose plastic with a wide range of applications and is used to make various products. However, PVC is a material with good insulation and is also prone to static electricity, so it is not suitable for use in occasions with high antistatic requirements. At the same time, PVC will decompose and pr...
