The invention summary
The invention provides composition for treating insect nets.Said composition when making the user preferably be applied to said composition on the mosquito account by injection, can be seen the change color in the mosquito account by fully painted, although said composition also can be by soaking into or other use means processing mosquito accounts.Said composition comprises colouring agent; Mosquito control material; And liquid-carrier.Preferably this liquid-carrier is an ejectable liquid, can spray or spray with the standard machinery injector by aerosol.
Term " mosquito control material " is defined as and comprises that insecticide, pest repellant and change mosquito grow or the material of behavior." mosquito " comprises real mosquito and uses other small animals of controlling with the same material of controlling mosquito and method usually.Term " liquid-carrier " comprises thinner, solvent etc., does not consider whether said composition integral body is solution, two-phase or multiphase liquid, suspension, emulsion or other forms of liquid preparation.
Preferably, injecting coloring agent or be applied on the mosquito account with additive method after just eclipsed.When being exposed in the air along with liquid-carrier drying or said composition (by the variation of pH value, oxidation, thermal change or other mechanism), colouring agent can turn pale.In preferred embodiment, colouring agent is visible color when a pH value, and eclipsed when the 2nd pH value, and composition changes to the 2nd pH value from a pH value in selected time after being applied to the mosquito account.A kind of colouring agent in preferred back is a thymolphthalein.
United States Patent (USP) 4681471 has been described one group of dyestuff that oxidation is eclipsed, as triarylmethane, triphenyl methane, cyanine and methine dyes.Herein with reference to quoting this patent and all patents enumerated and disclosed specification.Being selected from being exposed to of these materials is no less than the dyestuff that a few minutes (preferably being no less than 2 minutes) and no more than several days (preferred no more than 7 days) just are oxidized to colourless state easily and is applicable among the present invention in the air.
The Chromatic Technologies Inc. of the Colorado Springs of the state of Colorado has produced the thermochromism colouring agent, and this colouring agent is in the variable color of when heating or fade, and recovers primary colors after cooling.This technology is based on the dye encapsulated particle of when heating fusing.Fusing has changed the optical property of particle, makes it eclipsed.When particle cools off, solidify again and recover primary colors.The mosquito account of handling with this colouring agent can be processed into when hotter by day colourless, and recovers certain color when colder again at night.
The method that the present invention handles the mosquito account comprises provides composition for treating insect nets, said composition to comprise colouring agent, mosquito control material and liquid-carrier; Said composition is applied on the mosquito account; Step with dry mosquito account.Preferably, the composition that provides like this is after it is applied on the mosquito account, the composition that colouring agent wherein is eclipsed.Preferred, along with liquid-carrier dry or when being exposed in the air colouring agent eclipsed.
Most preferred, provide the step of composition for treating insect nets to comprise the composition that provides such, its colouring agent is visible color when a pH value, and eclipsed when the 2nd pH value, and said composition the back changes to the 2nd pH value from a pH value being ejected on the mosquito account sometime.This colouring agent is thymolphthalein preferably.
The present invention describes in detail
Below be the example that is used for composition for treating insect nets according to the present invention:
