Abstract

The invention relates to a PVC (Polyvinyl Chloride) tube, in particular to a manufacturing method of a cold bending electrical protective casing. The cold bending electrical protective casing is prepared from the following components by weight: 75 kg of PVC resin, 3.8 kg of composite stabilizer, 0.5 kg of stearic acid, 0.5 kg of chlorinated polyethylene, 3 kg of titanium dioxide, 0.6 kg of paraffin, 30 kg of light calcium carbonate and 1 kg of 401 auxiliary agent. The formula of the cold bending electrical protective casing is not influenced by seasonal temperature. The 401 processing modification auxiliary agent is added after adjustment, so that plasticizing, toughening and weathering resistance of the PVC product are promoted by a low-temperature modification toughing agent. By adding 401 into the PVC product, the PVC gelling and plasticizing effects can be promoted. Through plasticizing process operation, the PVC multiple particle structure is damaged, the release of primary particles of the PVC is promoted, a PVC extrusion processing process is formed, the plasticizing is quick, the viscosity is increased, and the thermal state strength is improved.

Description

technical field [0001] The invention relates to a PVC pipe material, in particular to a method for manufacturing a cold-formed electrical sheath pipe. Background technique [0002] Cold-formed electrical sheath pipes are mainly used to pre-buried underground wires in the early stage of buildings. In different seasons, the production technology and formula of the product need to be adjusted, otherwise it will become brittle in cold weather and soft in summer, and it is often difficult for customers to distinguish and distinguish during the sales process. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a method for manufacturing cold-formed electrical sheath tubes that are not affected by seasonal temperatures. [0004] The technical scheme that the present invention adopts is as follows: [0005] The cold-formed electrical sheath pipe is characterized in that it is made of the following c...
