Problems solved by technology

However, the dosage of valerythrin is very small, and there is no visibility on the carrier. How to show whether the drug is effective becomes a problem that must be solved when valerythrin is used in anti-moth products.

Embodiment 1

[0026] 1. Choose a thickness of 0.1mm and a bulk density of 0.2g / cm 3 First, make the filter paper into a suitable size, and then screen-print the ink containing the color developer on the filter paper, and the printed text is "It has expired, please replace it in time". Wherein the ink contains naphthol pyran with a mass percentage content of 6%, aluminum silicate with a mass percentage content of 54%, and diethylene glycol monobutyl ether with a mass percentage content of 40%;

[0027] 2. Use a roller applicator to evenly coat the pentamethrin on the carrier, and the thickness of the pentamethrin on the support is 50g / m 2 , the printed text disappears at this time.

[0028] 3. Cut into small pieces of 5 x 10 cm and pack them.

[0029] 4. When the valerythrin volatilizes, the font of "It has expired, please replace it in time" appears, indicating that it is necessary to replace the anti-moth agent.

Embodiment 2

[0031] 1. Choose a thickness of 4mm and a bulk density of 0.7g / cm 3 First, make the filter paper into a suitable size, and then screen-print the ink containing the color developer on the filter paper, and the printed text is "It has expired, please replace it in time". The ink contains 40% by mass of naphtholpyran, 40% by mass of aluminum silicate, and 20% by mass of diethylene glycol monobutyl ether.

[0032] 2. Use a roller applicator to evenly coat the pentamethrin on the carrier, and the thickness of the pentamethrin on the carrier is 60g / m 2 .

[0033] 3. Tailored and packaged to show whether it is an effective moth repellent.

[0034] 4. When the valerythrin volatilizes, the font of "It has expired, please replace it in time" appears, indicating that it is necessary to replace the anti-moth agent.

Embodiment 3

[0036] 1. Choose a thickness of 2mm and a bulk density of 0.6g / cm 3 First, make the filter paper into a suitable size, and then screen-print the ink containing the color developer on the filter paper, and the printed text is "It has expired, please replace it in time". The ink contains 28% by mass of naphtholpyran, 42% by mass of aluminum silicate, and 30% by mass of ethylene glycol monobutyl ether.

[0037] 2. Use a roller applicator to evenly coat the pentamethrin on the carrier, and the thickness of the pentamethrin on the support is 50g / m 2 .

[0038] 3. Tailored and packaged to show whether it is an effective moth repellent.

[0039] 4. When the valerythrin volatilizes, the font of "It has expired, please replace it in time" appears, indicating that it is necessary to replace the mothproofing agent.

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 [0001] The present invention relates to a method and production process that can indicate whether the anti-moth agent is valid during use, and specifically relates to a method that uses the color change of the color developer to indicate whether the anti-moth agent is effective during use and its production process. Background technique [0002] The products used in my country to prevent moth and mildew of clothes or books mainly include refined naphthalene, p-dichlorobenzene or camphor, which are directly punched into various shapes or wrapped in breathable paper, and put directly in wardrobes and other places when used. Refined naphthalene has been banned due to its chronic toxicity and carcinogenicity. The impact of p-dichlorobenzene on the human body has been controversial for a long time. At the same time, the pungent smell of p-dichlorobenzene is also difficult for consumers to accept. It has been regarded as a product that is not recommended for use i...
