Abstract

The invention discloses a polyvinyl chloride drain pipe and a preparation method thereof. The polyvinyl chloride drain pipe comprises the following raw materials in part by weight: 100 parts of polyvinyl chloride, 30 to 100 parts of hollow glass microsphere processed by coupling agent, 0.5 to 5 parts of thermal stabilizer, 0.5 to 5 parts of lubricating agent, 1 to 3 parts of titanium dioxide, 0 to 10 parts of flexibilizer and 0 to 2 parts of processing agent. The method adopts the mode of plastic modifying, creatively introduces the hollow glass microsphere for filling, effectively improves the product toughness on the basis that the product rigidity is guaranteed, simultaneously effectively reducing noises through a hollow structure, greatly reduces the product density, reduces the product weight, and can also reduce the product cost.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, in particular to a polyvinyl chloride drainage pipe and a preparation method thereof. Background technique [0002] Polyvinyl chloride is a low-cost and widely used general-purpose plastic, and it is more and more used in the fields of construction, water supply and drainage. In China, in order to reduce costs, many manufacturers fill PVC drainage pipes with a large amount of calcium carbonate, which significantly deteriorates the toughness of the product. Due to the high density of calcium carbonate, the weight of PVC drainage pipes is heavy, and it almost becomes a PVC drainage pipe. Negative image, at the same time, most of the PVC drainage pipes are laid in the exposed way, the sound insulation performance is poor, when there is water flowing in the pipe, there will be a rushing water flow sound, especially at night, the sound is more obvious, the noise problem is more prominent, direct...
