The content described in this paper involvesPVCLine tube production technology, specifically related to a.PVCConduit and its preparation method.PVCAs one of the products of the development of science and technology, tube can be seen everywhere in daily life. PVC wires and pipes are often used in daily life. PVC wire and tube is mainly made by adding calcium powder to PVC plastic and adding a series of additives. At present, in order to reduce the manufacturing cost, many manufacturers add too much calcium powder, and use calcium powder with large particle size and poor quality to add. In this way, the surface of the wire tube will not be smooth, the plasticity of the wire tube will be poor, and there will be no toughness.

The technical personnel provide a polyvinyl chloride conduit and a preparation method and process thereof.PVCThe surface of the line pipe is smooth, the toughness is high, and it is not easy to break. In order to achieve the above objectives, the technical scheme adopted by the present invention is: aPVCPipe line, PVC drain pipe is composed of the following components by mass: PVC resin95-100Light calcium carbonate45-60parts, chlorinated polyethylene6-10parts, stabilizers3-5parts, stearic acid0.6-1Paraffin wax0.6-1Pour, polyethylene wax0.35-0.45parts, polyethylene0.35-0.45copies. The particle size of light calcium carbonate is700-800Objective. The light calcium carbonate was modified by silane coupling agent. The stabilizer is a liquid zinc-barium composite stabilizer.

The specific preparation process steps are as follows: first, the proportion of polyvinyl chloride resin, light calcium carbonate, chlorinated polyethylene, stabilizer, stearic acid, paraffin,PEWax, anatase titanium dioxide, gold titanium and whitening agent, and then put into a high-speed mixer, in125 ~ 135mix under high temperature; mix20-30After minutes, cool45-50, Collect materials for standby; send the collected materials into the granulator for granulation to obtain granules. The rotation speed of the granulator is27-30r/min; After cooling, put the obtained particles into the barrel, and the temperature at the inlet end of the barrel is controlled190-200, the middle end temperature is controlled180-185, the outlet end temperature is controlled170-175, and then through the combination of core mold and mold device, to obtain the finished product. First willPVCThe resin is added to the high-speed mixer, then light calcium carbonate is added while stirring, and finally chlorinated polyethylene, stabilizer, stearic acid, paraffin wax,PEWax, anatase titanium dioxide, gold titanium and brighteners. this kindPVCconduit, including hollowPVCConduit body; hollowPVCThree partitions are arranged in the conduit body, and the three partitions are arranged in a herringbone pattern. This new type of PVC pipe line is also set up.PVCThe cross section of the tube body is a circular structure.

Compared with the existing technology, the above-mentioned utility model.PVCThe conduit has the following beneficial effects: the conduit body is provided with a herringbone partition, so that the PVC conduit can separate different types of wires, which is convenient for identification and replacement of wires. PVC conduit has the advantages of smooth surface, good plasticity, high toughness and not easy to break.
