Description
[technical field]
The present invention relates to cable technical field, specifically a kind of mouse bite preventing environmental protection cable wire formula.
[background technology]
Mouse is as a kind of reproductivity and the very strong rodent of vitality, it extensively lives in each area in the world, because its front tooth is very flourishing and can constantly growth, so muroid have object of nibbling keep the habit that its tooth is sharp, the distinctive smell of plastics makes plastics become muroid often to bite object.The report vole field cabling that bites often is had to cause the event of cable failure, and in urban house electric wire by mouse bite lost efficacy situation also happen occasionally, according to another statistics, there are 1/4th agnogenic fire in China, may be to be stung by mouse to damage caused by electric wire.So, the CABLE MATERIALS product of market in urgent need anti-rat.
And for ecological protection and the first-class factor of economy, lightguide cable link protection against rodents both should not take measures such as killing, catch and kill, also should not as optical fiber cable for direct burial, take buried depth prevent.Therefore, current optical cable ratproofing still also needs to rely on the structure design of optical cable and changes in material to prevent.Conventional protection against rodents scheme has adds the method such as chemical composition, employing multiple sheath armouring in sheath.Corning Incorporated once used the structure of double-level-metal armouring for built on stilts protection against rodents in Thailand, and optical cable own wt and external diameter are comparatively large, can improve, can add the cost of lightguide cable link to the requirement of built on stilts shaft tower.A kind of feasible structure is also had to be adopt the scheme of Stainless Steel Band, if but to be cut by Stainless Steel Band and after answering film, its material cost is 5 times of conventional chromium plating steel band, inadvisable economically.
Therefore, the century-old history of method of the most applicable employing adds the method for chemical composition in sheath, thus will work out the following several key problem in technology of mouse bite preventing environment-friendly cable material product needed solution:
(1) rodent-proof characteristic, due to environmental requirement, can not use the material of ratsbane and contaminate environment, can only use the Ratproof method of environmental protection, as added glass fibre, increasing the third body chemical substance, adding protection against rodents plastic cement auxiliary agent etc.So select suitable Ratproof method to be the key of technology.
(2) environmental requirement, because outlet needs, limit by European Union environmental protection, product needed meets European Union ROHS, RAOHS requirement.So select suitable starting material to be keys of technology.
(3) cable quality requirement, meet product standard requirement.So select suitable formula rate to be the key of technology.
[summary of the invention]
Object of the present invention is exactly will solve above-mentioned deficiency and provide a kind of mouse bite preventing environmental protection cable wire formula; not only there is rodent-proof characteristic, avoid mouse and sting the situation generation damaging cable, and very environmental protection; ensure that ecological protection and the first-class factor of economy, and ensure that the specification of quality of cable.
Design a kind of mouse bite preventing environmental protection cable wire formula for achieving the above object, comprise the raw material of following mass percentage content:
