Problems solved by technology

However, one of the cable materials of these two inventions is not a technical solution specially provided for the requirements of the national standard GB / T8815-2002, but is a suitable product for some special occasions such as ultraviolet protection, extreme cold and other environments. In addition, its cost are more expensive
[0004] In addition, some high-voltage resistance indicators and flame-retardant indicators of cables and electrical high-voltage products are usually a pair of contradictory requirements in the same product. At the same time, it is difficult to meet the requirements of high flame retardancy

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the embodiments.

[0014] 1. The preparation process of the cross-linked high flame-retardant foamed polyvinyl chloride modified material in the embodiment of the present invention is as follows:

[0015] Prepare raw materials according to the proportion of ingredients, first add polyvinyl chloride resin powder, polyester plasticizer, halogen-free flame retardant, cross-linking agent, calcium and zinc heat stabilizer into the mixer and stir at high speed for about 10 minutes, to 80 ℃ material temperature, Then add chlorinated polyvinyl chloride resin and stir at high speed for about 2 minutes to reach the material temperature of 100 °C. Finally, add talc, polyethylene PE and foaming agent and stir at high speed for about 8 minutes. When the material temperature reaches 100 °C, the material is discharged to the 150-type double A screw extruder performs plastic granulation. The temperatur...

Abstract

The invention discloses a crosslinked high flame-retardant foamed polyvinyl chloride modified material. The material comprises the following components in part by weight: 100 parts of polyvinyl chloride resin, 30 to 100 parts of nano talcpowder, 50 to 80 parts of high-temperature resistant polyester plasticizer, 20 to 100 parts of chlorinated polyvinyl chloride resin, 20 to 100 parts of polyethylene, 30 to 100 parts of halogen-free flame retardant, 5 to 20 parts of calcium zinc thermal stabilizer, 20 to 60 parts of cross linker and 10 to 40 parts of foaming agent. The material has excellent high-temperature resistance, high flame-retardant performance and excellent high-voltage electric resistance, and is particularly suitable to be used as a cable material with high flame-retardant requirement and used for a product shell.

Description

technical field [0001] The invention relates to a cross-linked high-flame-retardant foamed polyvinyl chloride modified material, in particular to a polyvinyl chloride modified material for use in foamed high-flame-retardant and high-pressure-resistant wire and cable sheathing materials and foamed high-flame-retardant product shells and other products Vinyl chloride modified material. Background technique [0002] PVC cable material is a common cable material, and different use environments have different requirements for PVC cable material. Polyvinyl chloride (Polyvinylchlorid, PVC), the main component is polyvinyl chloride, PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. In addition, polyvinyl chloride is mainly used to produce artificial leather, film, wire sheathing and other soft plastic products, and can also produce plastic hard products such as plates, doors and windows, pipes a...
