High-strength pipe based on HPVC and preparation method of high-strength pipe

Abstract

The invention provides a high-strength pipe based on HPVC and a preparation method of the high-strength pipe. The high-strength pipe is characterized by comprising the following raw materials in partsby weight: 50-60 parts of HPVC, 10-15 parts of CPVC, 10-20 parts of silicone oil with two amino end groups, 3-8 parts of nanometer boron fibers, 5-10 parts of amino-modified fullerene, 1-5 parts of acoupling agent, 2-4 parts of 1,3-adamantyl diacrylate, 2-4 parts of 3,5-bis(trifluoromethyl)styrene, 1-3 parts of diethoxydivinylsilane, 10-15 parts of a filler, 3-5 parts of a heat stabilizer, 1-3 parts of a lubricant and 0.05-0.1 part of an initiator. The invention further discloses a preparation method of the high-strength pipe based on HPVC. The HPVC-based high-strength pipe disclosed by theinvention has the advantages of more excellent comprehensive performance, good thermal stability and processing fluidity, and better strength, stress cracking resistance and impact resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an HPVC-based high-strength pipe and a preparation method thereof. Background technique [0002] In recent years, with the advancement of science and technology and the development of the economy, various pipes have sprung up into people's lives. They are closely related to people's lives and have become a part of people's lives. These pipes are widely used in construction, water conservancy, and bridges. , electric power transportation, communication, municipal pipe network and other fields play a very important role in human life. [0003] Many pipes in life need to be used underground, such as roads, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields and other water supply and drainage fields, as well as underground irrigation and drainage systems for agriculture and horticulture. The pipes used in these environments need to hav...

Problems solved by technology

HPVC high degree of polymerization polyvinyl chloride is an excellent raw material. Compared with ordinary PVC, HPVC has high molecular weight, long molecular chains and large curling, and more entanglement points between molecular chains, so that the interaction between HPVC molecular chains The force is enhanced, and the slippage between molecular chains is difficult; therefore, HPVC can provide high mechanical properties and heat resistance, and has excellent properties similar to rubber. Plastic pipes made of HPVC have high strength, high toughness, compression resistance, resistance Combustibility and recovery resistance, etc., can replace plastic-coated or galvanized steel pipes, cross roads or bridges as communication cable protection pipes, and can replace MPP and PE pipes for trenchless pipelines, but the thermal stability of HPVC and Poor processing fluidity and poor impact resistance limit its application in the engineering field
