Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment.

[0020] Adopting the formula provided by the invention to produce pipes comprises the following steps:

[0021] 1. Prepare the dosage of each component;

[0022] 2. Stir the prepared components evenly in a high-speed mixer. When the temperature of the mixture reaches 120°C, put it into a low-speed cold mixer for cold mixing. When the temperature of the mixture reaches 40°C, unload and set aside .

[0023] 3. Put the mixed material into the conical twin-screw extruder for extrusion processing and molding. Set the barrel heating temperature to 120-200°C, the die temperature to 120-200°C, the screw speed to 10-50rpm, and the feeding speed to 5-50rpm.

[0024] Components, parts by weight and processing parameters of specific examples are as shown in table 1,

Abstract

The invention provides a formula of a high-impact-resistance PVC (polyvinyl chloride) pipe. The high-impact-resistance PVC (polyvinyl chloride) pipe is prepared from PVC resin powder, organic coarse whiting, organotin stabilizer, calcium stearate, PE (polyethylene) wax, impact resistance agent, titanium white, epoxy soybean oil and processing assistants. Compared with the prior art, the PVC pipe prepared according to the formula provided by the invention has the characteristics of high strength, high toughness, high impact resistance, low composition price and high market competitive power.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a high-impact PVC pipe formula. Background technique [0002] The main component of PVC pipe is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. PVC is deeply loved in the world today, and it is quite a popular and widely used synthetic material. 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 and high strength, but its impact resistance is relatively poor. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and provides a high-impact PVC pipe material formulation with equal emphasis on strength and impact resistance. [0004] In order to achieve the above purpose, the following technical solution is adopted: a high-impact PVC pipe formulation comprisi...
