Abstract

The invention discloses a high-strength environmentally friendly polyvinyl chloride tube and a production method thereof. The high-strength environmentally friendly polyvinyl chloride tube comprises, by mass, 45-65% of polyvinyl chloride, 8-12% of glass fiber, 4-10% of wollastonite, 6-9% of di(2-ethylhexyl)phthalate, 5-8% of a methacrylate-acrylate copolymer, 5-9% of an environmentally friendly fire retardant, 1-2% of an antistatic agent HKD-912, 0.5-2% of an anti-ultraviolet absorbent, 0.5-1.5% of a leadless stabilizer, 0.5-1% of PE wax and 0.1-0.5% of an antioxidant 1010, and the environmentally friendly fire retardant is melamine cyanurate. The high-strength environmentally friendly polyvinyl chloride tube has the advantages of high impact strength, good mechanical performances, low cost, good heat stability, strong weather and corrosion resistance and good processability, and accords with environmental protection requirements.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a high-strength environment-friendly 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 it is used as a pipe, polyvinyl chloride has problems such as poor thermal stability, poor impact strength, and high temperature sensitivity, which will greatly limit its application range. Contents of the invention [0003] The object of the present invention is to provide a high-strength environment-friendly polyvinyl chloride pipe with good comprehensive performance a...
