Problems solved by technology

However, a large number of white PVC sheathed coaxial cables are also required in the actual application selection
Although white has a certain reflective effect on sunlight, white polyvinyl chloride will be brittle and cracked for a long time or under strong sunlight

Embodiment Construction

[0053] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.

[0054] A kind of anti-ultraviolet radiation ring protection sheath material, said sheath material is mainly prepared from the following substances by weight:

[0055] PVC resin 470 kg

[0056] Trioctyl trimellitate (TOTM) 70 kg

[0057] Dioctyl sebacate (DOS) 50 kg

[0058] Dioctyl phthalate (DOP) 70kg

[0059] Calcium Zinc Composite Stabilizer 50kg

[0060] Epoxidized soybean oil (ESO) 10 kg

[0061] Antimony trioxide 15 kg

[0062] Magnesium Hydroxide 100kg

[0063] Fine Calcium Carbonate 80kg

[0064] Titanium dioxide 80 kg

[0065] Ultraviolet absorber (UV-531) 5 kg.

[0066]The above-mentioned production process consists of three major processes of batching, mixing and extrusion. Batching is to mix various raw materials according to the formula; mixing is to mix various raw materials at high sp...

Abstract

An ultra violet radiation resistant environmental protection sheathing material is mainly prepared by the following materials according to the parts by weight: 40-50 pars of polyvinyl chloride resin, 6-8 parts of trioctyl trimellitate, 4-6 parts of dioctyl sebacate, 7-9 parts of dioctylphthalate, 4-6 parts of ca-zn composite stabilizer, 1-1.5 parts of epoxidized soybean oil, 1-1.5 parts of diantimony trioxide, 1-1.5 parts of diantimony trioxide, 10-13 parts of magnesium hydrate, 8-10 parts of refined calcium carbonate, 8-10 parts of titanium dioxide, and 0.3-0.5 parts of ultraviolet absorbent. The invention technically solves the difficult point of compound formulation of the ultra violet radiation resistant white sheathing material, greatly increases the resistance to ultra violet radiation performance of the product, has strong practicability and lays the material foundation for the design and development of resistance to ultra violet radiation coaxial-cables. Based on the resistance to ultra violet radiation white polyvinyl chloride sheathing material, the resistance to ultra violet radiation environmental protection sheathing material technically solves the technical difficulties of resistance to ultra violet radiation performance, softness, UL mechanical physical property, ROHS environment requirements and the like which are difficult to be achieved completely, meets the strict requirements of the application of products on tropical and subtropical regions and has remarkable social effect.

Description

(1) Technical field [0001] The invention relates to the field of wire and cable processing, specifically, the invention is an ultraviolet radiation-resistant ring protective sheathing material and an environmentally friendly ultraviolet radiation-resistant white coaxial cable that is used in tropical and subtropical regions and meets the requirements of UL and EU ROHS directives. . (2) Background technology [0002] Generally, the PVC sheathed coaxial cable is exposed to sunlight for a long time, and the PVC will "glow oil", become embrittled or even rupture. Especially in tropical and subtropical regions close to the equator, such as my country's Xinjiang, South Asia, India, Middle East and other countries and regions, this situation is more prominent, and customers complain more. [0003] Generally, the color of the sheath of the coaxial cable is black, because a certain proportion of carbon black is added to the black PVC sheath material, which has good ultraviolet radia...
