The invention discloses a kind of special termite-proof additives of cable, prepare with the following method：Termite killing agent is dissolved into organic solvent, then nano molecular sieve is immersed in the organic solvent, by the molecular sieve drying after dipping, it adds in the mixed solution of sodium aluminate and aluminum sulfate, the pH value of solution is adjusted under conditions of stirring to 68, after impregnating 1 10min, drying simultaneously crushes, and obtains the termite-proof additive.Additive of the present invention has the effect of cable life-cycle prevention termite.And the Additive Properties are stablized, and do not interfere with other additives in cable and have a negative impact.
Description
Technical field
The invention belongs to cable PVC material specialist additive more particularly to a kind of special termite-proof additives of cable.
Background technology
Termite damage is an important factor for causing buried cable failure, and according to statistics, 7 province of south China is every year because of termite damage
Caused cable fault is more than the 60% of total failare.Termite can not only destroy cable cover(ing) or even can break through metal carbonyl coat,
Cause the accidents such as transmission fault, electric leakage, power failure or even fire, explosion.Therefore, the termite control of buried cable, it is special in China
It is that southern area is particularly significant.
PVC cable material is cheap, function admirable, is occupied an important position for a long time in wire cable insulating protection materials,
But this material contains to environment and human harmful substance, and there are problems when applied to particular surroundings.With people
The enhancing of environmental consciousness and the raising to material performance requirement, propose PVC material higher requirement.
Endanger totally 18 kinds of the termite of cable.The termite of cable is endangered in China, mainly the formosanes category in Rhinotermitidae
And Reticulitermes.Due to the environment of termite hobby warm moist, generating heat when cable is run raises cable surrounding soil temperature, fits
Conjunction termite is nested and growth and development.Therefore the ecological environment on power cable periphery has termite certain sucking action, makes it more
It is subject to termite attack.After termite is by the cable jacket that bites, and enter inside cable.Termite enters generated row in cable
It is all acidic materials to let out object and secretion, there is very strong corrosiveness to cable so that cable is insulated in a short time by broken
It is bad, easily cause disconnected cable accident.In the cable fault repeatedly occurred, most of is exactly caused by termite attack.
The termite-proof method of buried cable can be divided into physical method and chemical method.Physical method mainly utilizes cable protection
The hardness of jacking and the smoothness of cable surface prevent termite attack.Research shows that shore hardness is more than 70 and surface is smooth
High molecular material, termite destruction can be effectively prevented, such as nylon 11, nylon 12, semirigid PVC, the poly- second of modification high-density
The materials such as alkene all have termite-proof performance, and using these material manufacture cable cover(ing)s, termite-proof effect is lasting, but manufacture cost
It is higher, therefore application is above subject to certain restrictions.
Chemical method is to be achieved the purpose that by insecticide or repellant termite-proof, and China just leads in the 1970s
Cross and Niran added in into cable jacket material, the organochlorine insecticides such as lindane come termite-proof, achieve good effect in practice.
In recent years, as the organochlorine insecticides such as the raising of environmental requirement, Niran are gradually substituted by the drug of some high-efficiency environment friendlies.With object
Reason method is compared, although chemical method lasting performance is slightly worse, has relatively low production cost, simple production process, to cable
The advantages that mechanical performance does not influence, therefore be widely used, still occupy master in current anti-termite cable market
Lead status.
During using chemical method, insecticide or repellant can be added directly in cable jacket material, can also be processed as
Functional masterbatch uses, and compared with directly adding insecticide or repellant, can be substantially reduced and produced using functional masterbatch
Safety, environment and hygienic risk in journey.China's related research at present and patent mostly by the way of directly adding, there is not yet
The anti-termite cable masterbatch of commercialization, partial cables manufacturer still have to female using the anti-termite cable of offshore company's production
Material, price is generally in 150,000 yuan/more than t, so that the cost of raw material greatly improves.Therefore, develop dependable performance, make
The relatively low anti-termite cable masterbatch of valency can effectively reduce the manufacture cost of anti-termite cable, improve the competitiveness of product.
The content of the invention
The technical scheme is that be accomplished by the following way：
A kind of special termite-proof additive of cable, prepares with the following method：Termite killing agent is dissolved into organic solvent
In, then nano molecular sieve is immersed in the organic solvent, by the molecular sieve drying after dipping, adds in sodium aluminate and sulfuric acid
In the mixed solution of aluminium, the pH value of solution is adjusted under conditions of stirring to 6-8, after impregnating 1-10min, drying simultaneously crushes, and obtains
To the termite-proof additive.
The termite biocide is the mass ratio of triazole derivative and Biphenthrin, the triazole derivative and Biphenthrin
For 5-10：1, the triazole derivative is one kind in Tebuconazole, Triadimenol, propiconazole.
The organic solvent is dimethyl carbonate, ethyl acetate, one kind in diethyl carbonate.
The molar ratio of sodium aluminate and aluminum sulfate is 1-3 in the mixed solution of the sodium aluminate and aluminum sulfate:1, the mixing
The molar concentration of Al ions is 0.1-0.5mol/L in solution, and the pH value of mixed solution is 1-3.
The grain size of the nano molecular sieve is 10-1000nm, preferably 10-100nm；Preferably large pore molecular sieve.
The present invention has the beneficial effect that compared with the prior art：
Termite-proof additive of the present invention overcomes directly directly to add directly in cable rubber materials in the prior art and kill
Agent of going out is easy to chemically react with other components, loses killing effect soon.The present invention is that termite biocide is direct
Then absorption utilizes the aluminium hydroxide of deposition over a molecular sieve by agent for killing in the molecular sieve pore passage with very strong adsorption effect
It is sealed in duct, after termite bites to cable, after running into the acidic materials secreted in termite body, aluminium hydroxide quilt
Dissolving, and killing agent is released, so as to achieve the effect that termite is killed in prevention.Additive of the present invention has the cable life-cycle
Prevent the effect of termite.And the Additive Properties are stablized, and do not interfere with other additives in cable and have a negative impact.
