Fire, weather and high temperature resistant polyvinyl chloride tube and production method thereof

Abstract

The invention discloses a fire, weather and high temperature resistant polyvinyl chloride tube and a production method thereof. The fire, weather and high temperature resistant polyvinyl chloride tube comprises, by mass, 55-78% of polyvinyl chloride, 6-12% of carbon fiber, 5-8% of a plasticizer, 3-6% of PETG, 2-5% of ACR, 2-4% of a fireproof agent, 1-3% of nanometer titanium dioxide, 1-2% of an antistatic agent HKD-912, 0.5-2% of an anti-ultraviolet absorbent UV-326, 0.5-1.5% of a calcium and zinc composite stabilizer, 0.5-1% of zinc stearate and 0.1-0.5% of an antioxidant. The fire, weather and high temperature resistant polyvinyl chloride tube has the advantages of strength increase, weather resistance, fire resistance, high temperature resistance, antistatic property, good mechanical properties, high strength, good processability, low cost, simple preparation process and wide adaptation range.

Description

technical field

[0001] The invention relates to the technical field of plastic pipes, in particular to a fire-proof, weather-resistant and high-temperature-resistant polyvinyl chloride pipe and a preparation method thereof. Background technique

[0002] Polyvinyl chloride (PVC) is one of the five general-purpose resins, and its output is second only to polyethylene (PE). Because PVC has the advantages of high chemical resistance, good electrical insulation performance, stable physical and chemical properties, and low price, At present, it has been widely used as raw materials for pipes, wires and cables, floors, etc. However, when used as a pipe, polyvinyl chloride has problems such as poor thermal stability, poor weather resistance, and low fire resistance, which will greatly limit its application range. Contents of the invention

[0003] The object of the present invention is to provide a fire-proof, weather-resistant and high-temperature-resistant polyvinyl chloride pi...
