Problems solved by technology

Therefore, when used in different temperature regions, it is necessary to prepare special PVC cable materials suitable for the temperature environment in the region, which brings great trouble to users who need to move in a large range (such as geology, oil exploration, army); secondly, the existing PVC cable materials Civilian outdoor use is also subject to certain restrictions, general PVC can only be used indoors at a temperature of -25-+70°C
Therefore, no general-purpose PVC cable material that satisfies all kinds of temperature zones from tropical to frigid zones (such as outdoor temperature difference -50°C to +80°C) and can be used outdoors has not yet been invented.

Embodiment

[0012] Embodiment: (see the attached table for the proportioning of group materials)

[0013] Preparation of polyvinyl chloride cable material 1: Blend PVC and EVA evenly, add plasticizer and other compounding agents, knead at 80-100°C at high speed, put into twin-screw plasticizing granulator for plasticization, pelletize and cool for packaging.

[0014] Preparation of PVC cable material 2: Copolymerize VC and M to obtain VC-M copolymer, then put VC-M copolymer and other compounding agents into a high-speed combined machine for kneading, and then put it into a twin-screw plasticizing granulator for plasticization. Diced and cooled for packaging.

Abstract

The invention discloses a polychloroethylene cable material for torrid zone and frigid zone, which comprises the following parts: 40-70%wt polychloroethylene resin and 30-60%wt ethylene-acetic acid ethyenyl ester copolymer composition or 70-95%wt vinyl chloride and 5-30%wt maleate copolymer, 20-35%wt dioctyl sebacate and or adipate dioctyl plasticizer, 0.3-1.6%wt ultraviolet adsorbent and 0.5-2.0%wt anti-fungus agent. The temperature scale of cable material is -50+80 Deg C, which is fit for frequent transmitting utility.

Description

technical field [0001] The invention relates to a polyvinyl chloride cable material, in particular to a general-purpose polyvinyl chloride cable material that can adapt to all temperature zones from tropical to frigid zones. Background technique [0002] Polyvinyl chloride (PVC) cable materials have different requirements in different environmental temperature conditions: in dry tropical areas, the outdoor sunlight temperature in summer is as high as +70 ℃ ~ +80 ℃, and there are strong ultraviolet rays at the same time, so sunlight aging and heat resistance are required Good performance; subtropical-humid tropics, except in summer when the outdoor temperature reaches +60℃~+70℃ under the sun, the air is humid, and plastics are prone to mold, which causes the moisture resistance and insulation of cables to decline. Climate aging; frigid regions: the minimum outdoor temperature in winter is around -50°C, the embrittlement temperature of soft PVC cable material is only -25°C, an...
