Problems solved by technology

However, the notched impact strength of PVC is only 5-10kJ / m 2 , there is also the problem of poor toughness
[0005] In order to improve the toughness of polyvinyl chloride, especially, in order to improve the notched impact strength, those skilled in the art have carried out some active attempts, such as the polyvinyl chloride composite material of Chinese patent CN 101948596A, which contains polyvinyl chloride 80-145 parts and 20-35 parts of thermoplastic polyurethane elastomer rubber can increase the notched impact strength of polyvinyl chloride to 13.5-17.4kJ / m 2 , but still low, it is difficult to meet the technical index requirements of the cable protection tube

Embodiment 2

[0048] (1) Preparation of premix:

[0049]In parts by weight, after measuring 55 parts of CPVC, 45 parts of PVC, and 3.5 parts of calcium / zinc stabilizer, put them into a low-speed mixer at room temperature and with a rotation speed of 100 rpm. After stirring for 2 minutes, slowly add 2 parts of KM-355ACR, B564ACR 2 parts, 1.5 parts of OP wax, 1.6 parts of polyethylene wax, 10 parts of talcum powder, 7 parts of hydrotalcite, 1 part of 1010 antioxidant, 12 parts of TPEE, and then stirred for 3 minutes to obtain a premix;

[0050] (2) Preparation of toughened power cable CV environmental protection tube:

[0051] Put the premix prepared in step (1) into a conical twin-screw extruder with a temperature of 110°C, 160°C, 175°C, 175°C, 175°C, 170°C and a screw speed of 100rpm, and plasticize Extrude the tube blank (inner diameter 100mm, thickness 5mm), after the tube blank is shaped, cooled and cut, the toughened power cable CV environmental protection tube can be obtained.

Embodiment 3

[0053] (1) Preparation of premix:

[0054] In parts by weight, after measuring 80 parts of CPVC, 20 parts of PVC, and 4.5 parts of calcium / zinc stabilizer, put them into a low-speed mixer at room temperature and with a rotation speed of 105 rpm. After stirring for 2 minutes, add 3 parts of A606ACR and 3 parts of KM334ACR slowly during the stirring. 1 part, 2 parts of OP wax, 1.6 parts of polyethylene wax, 1 part of 316 wax, 6 parts of talcum powder, 10 parts of hydrotalcite, 1 part of 245 antioxidant, 16 parts of TPEE, and continue stirring for 3 minutes to obtain a premix;

Abstract

The invention discloses a polyvinyl chloride composite material, which is prepared from the following components in parts by weight: 50 to 150 parts of polyvinyl chloride polymer and 5 to 20 parts of thermoplastic polyester elastomer, wherein the thermoplastic polyester elastomer is prepared from chlorinated polyvinyl chloride and polyvinyl chloride; the weight ratio of the chlorinated polyvinyl chloride to the polyvinyl chloride is 1 : (0.2 to 1.5). The invention also provides application of the polyvinyl chloride composite material in preparing a cable protection pipe. A toughened power cable CV environmentally-friendly pipe provided by the invention can well meet the application requirement when serving as the cable protection pipe, is not only suitable for being used as a protection pipe when an electric power and communication cable is paved underground, but also suitable for being used as a protection pipe when a cable is directly buried in a carriageway, paved in a vital communication line crossing, crosses a bridge and a river and in other special environments, is also applicable in the engineering construction fields such as power grid construction and renovation, and city municipal renovation, and has a very wide market prospect.

Description

technical field [0001] The invention relates to a toughened power cable CV environmental protection pipe and a preparation method thereof. Background technique [0002] Cable protection tube, also known as cable tube, power cable tube, cement cable tube, power pipe, power cable protection tube, etc., it is set on the outside of the wire and cable to protect it, avoiding the mutual influence between cables and The impact of other surrounding pipelines on the cable. With the rapid development of electric power industry and communication industry, environmental protection issues have gradually attracted people's attention. Cables into the ground have been widely promoted in the construction and transformation of urban power grids, making cable protection tubes more and more widely used. [0003] Traditionally, most cable protection tubes are made of FRP, which can protect wires and cables, etc., but the cable protection tubes made of FRP have a high density and are relatively ...
