Plastic coated material for non-flange plastic coated pipe and preparation method thereof

Abstract

The invention discloses a plastic coated material for a non-flange plastic coated pipe and a preparation method thereof. The plastic coated material comprises the following raw materials in parts by mass: low density polyethylene resin, an ethylene-vinyl acetate copolymer, a fire retardant, an initiating agent, an antioxidant, an antistatic agent, epoxidized vegetable oil, an environment-friendly stabilizer, an environment-friendly plasticizer, white oil, a viscosity reducer, liquid paraffin and light calcium carbonates. The plastic coated material disclosed by the invention is less in toxicity and environment-friendly and better protects producers, users and natural environments; in case of fire emergency, only a little smog generates, a fire source is favorably distinguished and people escape easily; the plastic coated material is good in hand feeling, non-sticky and smooth in surface and has better market competitiveness.

Description

technical field [0001] The invention relates to a plastic-coated material for pipes, in particular to a plastic-coated material for flangeless plastic-coated pipes and a preparation method thereof. Background technique [0002] At present, the commonly used plastic coating materials for pipes on the market are generally heat-processed by physical methods, or the plastic resin is dissolved in a solvent to form a solution and then dried and cured to obtain a plastic protective layer; among them, the heat-processed material is attached to the material after heating. Steel pipe surface, this method is only suitable for small-diameter steel pipes, and large-diameter plastic-coated steel pipes similar to petrochemical enterprises and oil factories can only be processed by curing and drying functional materials such as epoxy resin, which is not only labor-intensive and time-consuming It meets the characteristics of environmental protection requirements.
