Polyvinyl chloride tube containing modified attapulgite and preparing method thereof

Abstract

The invention discloses a polyvinyl chloride (PVC) tube containing modified attapulgite and a preparing method thereof. The PVC tube containing the modified attapulgite is composed of raw materials comprising, based on the weight part ratio, 65-70 parts of SG-7 type PVC resin, 40-45 parts of high density polyethylene, 1-3 parts of poly-4-methyl-1-pentene, 2-4 parts of methyl methacrylate-butadiene-styrene terpolymer, 1.3-1.8 parts of alkylphenol ethoxylates, 2-3 parts of modified attapulgite, 25-30 parts of light calcium carbonate, 1-1.5 parts of dimethyl dimercapto acetic acid ethylhexyl acrylate stannum, 1.3-1.8 parts of diisobutyl phthalate, 0.9-1.1 parts of fungacetin, 1-2 parts of zinc sulfide and 0.4-0.6 part of methyl triethoxysilane. According to the PVC tube containing the modified attapulgite and the preparing method, a formulation is further optimized, the composition of the modified attapulgite 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 attapulgite 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 t...
