Embodiment 1

[0019] Example 1: PVC pipes containing modified tree ashes, the weight parts (kg) of the raw materials are: SG-5 type PVC resin 60, polymethacrylate 40, poly-4-methyl-1-pentene 1.8, anti-impact agent ACR2, Span 60 1.8, calcium zinc stabilizer 1.3, modified tree ash 2, superfine talcum powder 35, resorcinol 0.7, n-butyl methacrylate 0.4, carbon black 2 and silane coupling Agent KH550 3.

[0020] A preparation method for a pvc pipe containing modified tree ash, comprising the following steps:

[0021] (1) Weigh each raw material according to the weight of the raw materials, add SG-5 PVC resin and polymethacrylate into the hot mixing pot, heat for 2-3 minutes, and then add poly-4-methyl-1 -Amylene, anti-impact agent ACR, Span 60, calcium zinc stabilizer, modified tree ash, superfine talcum powder, resorcinol, n-butyl methacrylate, carbon black and silane coupling agent KH550, mixing materials 5-7 minutes;

[0022] (2) Then add it to a parallel twin-screw extruder for melt blen...

Abstract

The invention discloses a polyvinyl chloride (PVC) tube containing modified tree ash and a preparing method thereof. The PVC tube containing the modified tree ash comprises compositions of, by weight part ratio, 57-63 parts of SG-5 type PVC resin, 37-43 parts of polymethacrylate, 1.5-2 parts of poly-4-methyl-1-pentene, 1-3 parts of impact modifier ACR, 1.5-2 parts of Span60, 1.2-1.4 parts of calcium-zinc stabilizer, 1-3 parts of modified tree ash, 33-38 parts of superfine talcum powder, 0.6-0.8 part of resorcinol, 0.3-0.5 part of methacrylic acid emulsification, 1-3 parts of carbon black and 2-4 parts of silane coupling agent KH550. According to the PVC tube containing the modified tree ash and the preparing method thereof, a formulation is further optimized, the modified tree ash is added in the formulation, and therefore dispersion of inorganic fillers is promoted and fluidity of PVC fusant is improved during the manufacturing process of the PVC tube, and furthermore tensile strength and breaking elongation are improved, toughness is good and hardness is low. In addition, the preparing method is simple and effectively applied to every walk of life.

Description

technical field [0001] The invention relates to the field of PVC pipe production, in particular to a PVC pipe containing modified tree ash and a preparation method thereof. Background technique [0002] The main component of pvc pipe is polyvinyl chloride, and plasticizers, anti-aging agents and other auxiliary materials are added to increase its heat resistance, toughness, ductility, etc. pvc is loved, popular and widely used in the world today. A synthetic material used, PVC pipe is a mature pipe, mainly used in water supply and drainage projects, PVC pipe has the advantages of acid resistance, alkali resistance, corrosion resistance, high strength, etc. The impact resistance of PVC pipes is not good, especially in the plasticizing process in the processing of PVC products, the dispersion of inorganic substances and the processing fluidity of PVC melts have always been difficult problems. Contents of the invention [0003] The object of the present invention is to p...
