Technical field
The present invention relates to cable material technical field, and in particular to a kind of novel ratproof optic cable and preparation method thereof.
Background technology
People are especially lived, the great fiber optic cable communications equipment of work influence by plastic products, in actual applications except
Outside destruction by environment such as oxygen, heat, power, chemical erosions, the biological food erosion injury such as termite, mouse is also suffered from.
At present, although conventional nylon rodent-resistant cable suffers from very serious ground in mouse with good rodent-proof characteristic
Area, still can not effectively prevent other rodents, nylon sheath wire is baited by mouse for a long time, and nylon sheath wire can be gnawed through, though
So also have and thicken steel belt protection, but also have rodent and steel band is broken into two with one's hands to the sleeve pipe and optical fiber for baiting the inside from lap-joint,
Cause damage.
And the sheath material of many rodent-resistant cables all reaches the purpose of protection against rodents using addition repellant on the market.On driving
Agent is kept away, the species studied a few days ago has cycloheximide (such as actidione), terpenoid compound monomer, borate compounds and fragrant phosphorus
Metal salt of acid esters etc., it mainly reaches the effect of repellent muroid by intense stimulus mouse oral mucosa；Also have using conjunction
The effect of protection against rodents is reached into the repellant of capsaicine composition.But all there is a series of lack in the repellant that the studies above is used
Fall into, severe toxicity that these rat destruction medicines have, the heat endurance that is expensive, having having is bad, half-life period that is having is shorter, have it is lasting
Property it is very poor, protection against rodents effect is limited, also often with irritating taste, there is certain injury to human body, does not meet to register one's residence and uses
General requirement.
The content of the invention
, being capable of long-acting, height it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of nontoxic to environment
Effect walks quickly and keeps away the novel ratproof optic cable sheath of mouse.
