Abstract

The invention discloses a preparation method of an impact-resistant UPVC cold-bending electrical bushing. The impact-resistant UPVC cold-bending electrical bushing comprises the raw materials of UPVCresin, light calcium carbonate, composite stabilizer, titanium dioxide, impact-resistant modifier, paraffin, stearic acid, chlorinated polyethylene, weather-proof auxiliary and processing modifier. Byuse of the raw materials, the electrical bushing has good impact resistance; a vacuum cooling setting device for cooling setting of the electrical bushing is used for performing cooling setting twiceon a high-temperature UPVC cold-bending electrical bushing blank by use of cold air and clear water, so that the temperature reduction rate of the high-temperature UPVC cold-bending electrical bushing blank is high, the cooling effect is good, and the device is high in cooling setting efficiency and good in setting effect; and cyclic use of the cold air is realized through the device, temperatureand pressure dynamic balance in the device is maintained, energy consumed by the device is low, cyclic use of water resources is completed, and waste of the water resources is avoided.

Description

technical field [0001] The invention relates to the technical field of electrical bushing production, in particular to a preparation method of an impact-resistant UPVC cold-formed electrical bushing. Background technique [0002] Electrical bushings are used in normal indoor environments and places with high temperature, dust, vibration and fire hazards, and can also be used in humid places. The ambient temperature is -15°C to +40°C, and the working pressure exceeds 2.5Mpa, but The existing electrical bushings still have the following deficiencies: (1) The existing electrical bushings have low compressive strength, poor impact resistance, are easily damaged during use, and have a short service life. [0003] Therefore, the vacuum cooling and setting device for electrical casing cooling and setting is particularly important. The patent application number of 201320004989.4 discloses a vacuum setting device. The cooling setting of the vacuum setting device is reliable, and the ...
