Example Embodiment

[0016] Example 1:

[0017] A high-strength environmentally friendly polyvinyl chloride pipe, whose components are proportioned by mass percentage: polyvinyl chloride 45%, glass fiber 12%, wollastonite 10%, bis(2-ethylhexyl phthalate) ) 9%, methacrylate-acrylate copolymer 8%, melamine cyanurate 9%, antistatic agent HKD-912 2%, anti-ultraviolet absorber UV-326 2%, calcium zinc stabilizer 1.5%, PE wax 1%, antioxidant 1010 0.5%, the glass fiber is an alkali-free glass fiber with a surface treated with a silane coupling agent, a diameter of 4-18μm, a length of 3-6mm, and an aspect ratio of 7-9. Wollastonite is a fibrous wollastonite whose surface has been modified by a silane coupling agent and has a diameter of 6-25 μm, a length of 10-500 μm, and an aspect ratio of 3-100.

[0018] Preparation method: (1), weigh each component according to the weight ratio; (2), add polyvinyl chloride, bis(2-ethylhexyl phthalate) and calcium zinc stabilizer into the barrel temperature at 80 In the mix...

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...
