Abstract
The invention relates to a method and a production technology thereof. The method utilizes a visualization reagent to indicate whether a mothproofing agent is in a period of validity or not. In the invention, through printing suggestive patterns or words on a carrier by special printing ink containing the visualization reagent, the patterns or the words present colors at the time so as to be clearly seen by naked eyes; then the mothproofing agent is uniformly coated on the carrier, the printing ink is in contact and reacts with the mothproofing agent at the time, and the patterns turn to be transparent or colorless. When the mothproofing agent basically volatilizes, the suggestive patterns or the words appear again so as to remind consumers of invalidation. The invention overcomes the problem that people hardly identify whether a product is used up or not due to small consumption of sumicidin and has convenient use.
Description
Technical field
The present invention relates to a kind of moth repellent of can indicating in use whether in the method and the production technology of the term of validity, specifically relate to a kind of change color of utilizing developer and indicate moth repellent in use whether effective method and production technology thereof.
Background technology
The product that China is used for clothing or books moth-proof and mould-proof mainly contains refined naphthalene, p-dichlorobenzene or camphor, directly strikes out different shape or is wrapped in the air-permeable paper, directly throws in places such as wardrobes during use.Refined naphthalene is because of its chronic toxicity and carcinogenicly ban use of.P-dichlorobenzene is controversial for a long time to the influence of human body, and the penetrating odor of p-dichlorobenzene also makes the consumer be difficult to accept simultaneously, and a lot of countries are as the product of not recommending to use.Camphor cost height, volatile quantity is big, and the suspicion of the secondary pollution of causing is arranged.P-dichlorobenzene and camphor generally can only keep 2～3 months mothproof effect, because it is when volatilizing naturally, the camphor about 3g all was evaporated completely at 30 days.
Alkynes valerate (English name: empenthrin, CAS No:54406-48-3) is a kind of pyrethroid insecticides of synthetic, has the advantage of broad-spectrum high efficacy, quick-acting and low toxicity.Use the alkynes valerate as moth repellent, as carrier, cost is low with the scraps of paper, and volatile quantity is few, and mothproof effect is good, and the mothproof time is long, general 3～12 months/sheet.But,, make on the scraps of paper, accurately to drip very difficulty of medicine, and China agricultural chemicals portion is about there being clearly restriction on the utilization of pesticides amount exactly because alkynes valerate consumption is few.And self diffusivity of alkynes valerate is not very strong, if adopt the production method of dripping medicine or spray medicine on carrier, has no idea to guarantee the even distribution of medicine.Therefore it is big indivedual scraps of paper pastille deviations to occur when making the little scraps of paper again, or even substandard product.
The vapour pressure height of alkynes valerate, the natural volatilization time is long, and the wardrobe that the scraps of paper of general 60～300mg content can be used for 50～500L keeps 6 months mothproof effect.But the consumption of alkynes valerate is very little, does not possess observability on carrier, how to show whether medicine effectively is used for the problem that mothproof product must solve with regard to becoming the alkynes valerate.
Summary of the invention
Primary and foremost purpose of the present invention is to propose a kind of indication moth repellent effective method whether in use
Another purpose of the present invention is to propose a kind of production technology of moth repellent of whether effectively can indicating in the use.
For realizing goal of the invention of the present invention, the technical scheme that is adopted is:
A kind of indication moth repellent is effective method whether in use: earlier with suggestive pattern or literal with containing the ink printing of developer on carrier, on carrier, evenly coat moth repellent again, pattern or the literal of this moment are transparent or colourless, after moth repellent volatilization drug effect disappears, developer presents color, and moth repellent lost efficacy thereby indication appears in pattern or literal.
The consisting of of printing ink of employing invented by this institute: mass percentage content is that 60～80% developer and mass percentage content are 20～40% solvents.Described moth repellent is preferably the alkynes valerate.
Solvent of the present invention is selected from ethylene glycol monobutyl ether or diethylene glycol monobutyl ether.
Consisting of of developer of the present invention: mass percentage content is that 10～50% pyran derivate and mass percentage content are 50～90% alumina silicate; Developer is formed and to be preferably: mass percentage content is that 20～40% pyran derivate and mass percentage content are 60～80% alumina silicate; The preferred naphthols pyrans of pyran derivate.
Alkynes valerate among the present invention content on carrier is 30～100g/m
2
Carrier among the present invention is that thickness is 0.1～4mm, volume density 0.2～0.7g/cm
3Wood pulp paper or rag paper.
Of the present inventionly can indicate whether that in use the production technology of effective moth repellent is: the ink printing that will contain developer is to carrier, then the alkynes valerate is evenly coated on the carrier, cut out, pack to such an extent that can in use indicate whether effective moth repellent.
The present invention selects for use purity greater than the direct roller coating of 92% alkynes valerate.
The tumbling-type coating machine that the present invention adopts is taken turns, is gone up parts such as lower bearing bracket, gear set, belt pulley, motor, powder charge box, control hand wheel by upper pressure paper sheet roller, middle coating wheel, following coating and forms.The tumbling-type coating machine that the present invention adopts is by motor-driven, by vee-pulley, vee belt, make lower shaft gear driven gear group, make upper pressure paper wheel, middle coating wheel, coating wheel rotation down, by adjusting the lifting structure of powder charge box, make down coating wheel and the interior in running order position of liquid medicine of powder charge box, quantitatively take medicine out of and reach the roller coating purpose.Regulate the gap of rotating speed and middle coating wheel, following coating wheel, control coating layer thickness reaches the requirement that is coated with dose, suitably adjusts control hand wheel to requiring the position according to the specification of workpiece simultaneously.
The present invention proposes a kind of production technology of moth repellent whether effectively of can showing: being used to of will designing reminds consumer and pattern or literal with containing the ink printing of special developer to carrier, then the alkynes valerate is evenly coated on the carrier, cut out, pack to such an extent that whether effectively can show moth repellent.
Whether the demonstration moth repellent that the present invention proposes effective method, be by adopting a kind of printing ink that adds developer, this developer has wet quick property and photonasty, can break the structure of colour developing composition when running into solvent, water or chrysanthemum esters product, thus Show Color not.Along with the volatilization of solvent, water or chrysanthemum ester, the colour developing composition recovers to show shades of colour automatically.In of the present invention, after the volatilization of alkynes valerate, developer can demonstrate pattern and the color that is printed on the carrier automatically, and the prompting people need change moth repellent.
The present invention preferably adopts ink printing that the mode of serigraphy will contain developer to carrier, and the size of design is relevant with the amount of using specialty inks.But, so long as on the scraps of paper roller coating alkynes valerate at 30g/m
