Abstract

The invention discloses a flame-retardant anti-static PVC (Polyvinyl Chloride) tube and a preparation method thereof. The flame-retardant anti-static PVC tube comprises the following raw materials: a polyvinyl chloride resin, a filling agent, a stabilizer, an impact modifier, a lubricant, an inorganic flame retardant and an anti-static agent, wherein the anti-static agent consists of calcined kaolin, conductive carbon black and titanium dioxide; and the inorganic flame retardant consists of brucite powder and sepiolite. The preparation method comprises the following steps: 1) mixing the filling agent, the inorganic flame retardant and the polyvinyl chloride resin for 2-5 minutes at a high speed; and 2) further adding the impact modifier, the stabilizer, the lubricant and the anti-static agent into the mixture of the step 1), mixing for 10-15 minutes at 100-110 DEG C, after uniform mixing, transferring into a cooling stirring, stirring for 3-5 minutes at 40-50 DEG C at a slow speed, and finally performing extrusion by using a conical two-screw extruder at 180-190 DEG C, thereby obtaining the tube. The tube is good in flame retardancy and anti-static property, and can be applied to fields such as marsh gases and coal.

Description

technical field [0001] The technical field of PVC pipes of the present invention particularly relates to a flame-retardant and antistatic PVC pipe and a preparation method thereof. Background technique [0002] PVC (full name Polyvinylchlorid) is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. [0003] PVC pipe (PVC-U pipe) rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., ...
