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...
