Description
(1) technical field
The present invention relates to the electric wire manufacture field, specifically, the present invention be a kind of ultraviolet light resistant ring protection jacking and make be used for the environmental protection ultraviolet light resistant white concentric cable that the torrid zone, subtropical zone meet UL and the ROHS of European Union command request.
(2) background technology
General pvc sheath concentric cable is subjected to sun exposure for a long time, and polyvinyl chloride " bleed ", embrittlement can take place even breaks.Especially in the torrid zone, subtropical zone near the equator, as countries and regions such as Xinjiang of China, South Asia, India, the Middle East, this situation performance is comparatively outstanding, and the client complains more.
The sheath color of general concentric cable is selected black for use, because add the carbon black of certain proportioning in the black pvc sheath material, has good ultraviolet light resistant performance.If select the high-carbon black pigment of polymolecularity for use, can satisfy the test requirements document of UL UV resistant.But, also need a large amount of white pvc sheath concentric cable in the practical application type selecting.Although it is white has certain reflex action to daylight, long-time or under sun exposure by force, white polyvinyl chloride embrittlement also can take place and breaks.
Through research, developed a kind of white pvc sheathing compound, and made the ultraviolet light resistant white concentric cable of a kind of UL of satisfying and the ROHS of European Union requirement with its design, obtained significant ultraviolet light resistant effect.

(2) You Yi environmental-protecting performance:
Material selection has taken into full account the requirement of the environmental protection index of ROHS instruction in the CABLE MATERIALS formulating of recipe:
The composite elasticizer system all meets the ROHS command request, and can give goods good performance such as fast light, heat-resisting, ageing-resistant.
Calcium zinc stable composition system is the optimal stablizer of present environment-friendly polyvinyl chloride CABLE MATERIALS.
Epoxy soybean oil plays softening agent and auxiliary stabilizer in PVC, particularly be used with calcium-zinc composite stabilizing agent, can effectively improve thermostability.
Other system component all adopt the environmental protection auxiliary agent.
CABLE MATERIALS meets the electronic apparatus ROHS of European Union instruction (2002/95/EC number instruction of European Union) requirement fully through the test of Shanghai SGS inspection center.
Contriver's recommendation realizes white concentric cable performance judgement of the present invention from following aspect:
(1) You Yi ultraviolet light resistant performance and flexibility preferably:
Cable detects through authoritative department, satisfies the anti-sun exposure test requirements document of UL fully.The Shore hardness of sheath material is 75, has kept flexibility preferably, and the flexibility of whole cable meets installs the needs that lay.
(2) You Yi environmental-protecting performance:
The overall construction design of cable and material selection have taken into full account the requirement of environmental protection index, and the cable finished product meets the electronic apparatus ROHS of European Union instruction (2002/95/EC number instruction of European Union) requirement fully through the test of Shanghai SGS inspection center.
Beneficial effect of the present invention: (1) has solved the difficult point of ultraviolet light resistant white sheath material formulating of recipe technically, and greatly improved the ultraviolet light resistant performance of this product, practical, for the raw material basis has been established in the design and the exploitation of ultraviolet light resistant concentric cable; (2) based on ultraviolet light resistant white pvc sheathing compound, successfully developed the ultraviolet light resistant white concentric cable that meets UL and ROHS requirement, the technological difficulties that ultraviolet light resistant performance, flexibility and UL mechanical and physical performance, ROHS environmental requirement etc. are difficult to reach have comprehensively been solved technically, satisfied the harsh requirement that product is used in the tropical and subtropical zone area, obvious social benefit; (3) the present invention fully takes into account the factors such as effective control of feasible, cost of realization, the technology of function in design, satisfy composite requests such as environmental protection under the environment for use, anti-sun exposure, softness, its exploitation and production meet the developing direction of national new high-tech industry.
