Description

A kind of vaporized insect-proof mother that suppresses insect growth in the fur

Affiliated technical field

The present invention relates to a kind of composition that suppresses the vaporized insect-proof mother of insect growth in the fur and preparation method thereof, belong to the Biofunctional materials technical field.

Background technology

Along with the raising gradually of living standards of the people, people daily live, with, use the more and more of fur goods in wearing, fur goods is good looking appearance but also durable not only, has improved the class that people live greatly.But the fur goods estivate is the problem that makes many people's headaches, because the high temperature humidity in summer, the fur goods keeping is not good at just may occurring phenomenon mouldy, rotten, " snake ", has had a strong impact on being extensive use of of fur goods.

For various museums, a large amount of animal or plant specimen of depositing and the book document data in Library, Vermins-proof mildew-proof also is a very important job.Up to the present, the also good without comparison way of the Vermins-proof mildew-proof of zoological specimens in domestic many museums, some adopts a kind of aerosol of import, and toxicity is bigger, and operation is frequent, uses very inconvenient.

From the kind of insect, the insect of harm sample shop sample mainly contains kinds such as lasioderma serricorne, Trogoderma variabile Ballion, the black worm of rice, attagenus piceus.

In order to tackle these insects, China most of sample shop is generally adopted at present and is thrown in wormer, purifying treatment, chemicals immersion, smears or with methods such as chemical agents sample carried out fumigation and kill.Sample before putting in storage is carried out purifying treatment, in order to avoid bring new worm source into, that generally uses has physical methods such as cryogenic freezing, baking oven for heating.Chemical process is with poisonous pharmaceutical chemicals sample to be fumigated, smeared or soaks.Smear and soak medicine commonly used mercury chloride, formalin, santochlor etc. are arranged.The medicine that fumigant insect killing is commonly used has aluminium phosphide, prussic acid, monobromethane, sulfuryl fluoride, santochlor, dithiocarbonic anhydride, sulfuryl fluoride, aluminium phosphide, phosphuret-(t)ed hydrogen etc.The sample shop that has we can say that insect pest problem in sample shop is not solved at home yet because the input deficiency only use mercury chloride insect protected and desinsection, but the effect of these methods is not remarkable.

Methods such as gamma radiation desinsection, microwave desinsection, gas regulation processing, electronic insect-killing and light wave insecticidal are also used in external many samples shop in research except purifying method, chemical processes such as employing cryogenic freezing.Gamma radiation and microwave all have limitation, can only be used for a small amount of sample, and gamma radioactive method expense costliness, used by country's restriction.Microwave box heating is inhomogeneous during microwave desinsection, and each corner temperature in the case is different, and insect can not all kill, and some sample also can explosion in the treating processes, and sample is damaged, and effect is undesirable.It is that damaged by vermin sample is placed in the oxygen barrier film sack that gas regulation is handled, and with oxygen scavenger oxygen content in the bag is reduced to below 0.1%, or is processing 7-21 days in the nitrogen environment of 60% carbonic acid gas or 99.9%, kill pests safely and effectively in concentration.Electronic insect-killing is slightly to bombard with low-energy electron in radiation devices, and light wave insecticidal is to use the near-infrared light waves detection scanning, only is used to kill foodstuff pests such as cereal, effectively kill pests in the Germany and the U.S. at present.The 3 kinds of methods in back had both been protected environment, and were with low cost, do not damage sample again, and the insect protected that is used for sample should be effective.But at present that is that all right is ripe for technology, also needs long research, could confirm its effect.

In most of museums, more valuable sample is all taked independent packaging and storing, the method of best like this Vermins-proof mildew-proof is not that whole indoor environment is handled, but should handle the small packages environment, that is to say and develop a kind of effective insect protected wrapping material, this material being made into small packages, sample is packed separately, is the most feasible present method.
