Formula of flame-retardant polyethylene plastic

Abstract

The invention discloses a formula of flame-retardant polyethylene plastic. The flame-retardant polyethylene plastic comprises polyethylene plastic and additives, wherein the additives comprise antimony oxide serving as a flame retardant, dilauryl thiodipropionate serving as an antioxidant, benzophenone serving as a light stabilizer, polyoxyethylene stearate serving as an antistatic agent, acrylate copolymer serving as an impact modifier and dimethylaminopropylamine serving as a cross-linking agent. After the auxiliary additives such as the flame retardant, the antioxidant, the light stabilizer, the antistatic agent and the impact modifier are added during production and processing, the flame-retardant polyethylene plastic has flame retardance, oxidation resistance, ultraviolet absorption property, high mechanical properties and the like; and by the cross-linking agent, the stability of the additives and the polyethylene plastic can be adjusted, and the properties of the polyethylene plastic product are balanced.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a flame-retardant polyethylene plastic formula. Background technique [0002] The replacement of metal by plastic has been promoted in many fields. According to the requirements of the five ministries and commissions, after 2000, cast iron pipes will be gradually eliminated and replaced by plastic pipes. Plastic pipes have the advantages of good corrosion resistance, low cost, light weight, long life, and convenient installation. However, plastic pipes also have extremely It is easy to generate static electricity, flammable, low pressure resistance and impact resistance, complex production formula, inconvenient operation and other shortcomings. Therefore, polyethylene materials need to be further adjusted to improve and perfect their performance, especially for underground mining plastics. Need to adapt to harsh environmental conditions, but also need to improve its antistatic, flame retarda...

According to the requirements of the five ministries and commissions, after 2000, cast iron pipes will be gradually eliminated and replaced by plastic pipes. Plastic pipes have the advantages of good corrosion resistance, low cost, light weight, long life, and convenient installation. However, plastic pipes also have extremely It is easy to generate static electricity, flammable, low pressure resistance and impact resistance, complex production formula, inconvenient operation and other shortcomings. Therefore, polyethylene materials need to be further adjusted to improve and perfect their performance, especially for underground mining plastics. Need to adapt to harsh environmental conditions, but also need to improve its antistatic, flame retardancy, strength, toughness, etc.
