Description

FIELD OF THE INVENTION [0001] The present invention relates to a method for manufacturing a fruit bag for insecticidal and insecticidal use,

The present invention relates to a fruit bag for protecting fruits from germs and insects, which is used for cultivation of fruit trees. In particular, it protects apples, pears, peaches and grapes of fruit juices from harmful insects and pests, And to a method of manufacturing a fruit bag for reducing the residual pesticide and improving the appearance.

In general, fruit bags provide favorable light quantity, temperature and humidity environment for fruits in the process of fruit growth and maturity, prevent natural disasters such as bird damage, hail, and damage by workers, and reduce residual pesticides It is also used to increase the profitability of fruit to be harvested. Fruit juice is sometimes inevitably sprayed with pesticides. Fruit bags also prevent pesticides from directly adulterating into fruits.

These fruit bags are usually made up of two layers (inlay and outer) of paper, one side open to see the inside, and the other sides to seal the contents in the inside so that they do not leak out and are sealed by bonding. Herein, inlay and outside are coated with a water-repellent coating solution to protect fruit from germs and insects.

Korean Utility Model Application No. 2000-0010326 discloses a three-ply algae and hail-prevention fruit protection pouch which is a special polyester non-woven fabric, which is a pulp fabric, which is a cover cloth.

Korean Patent Laid-Open Publication No. 10-2003-0005671 discloses a method for producing a primary mixed composition by mixing cooking oil and paraffin having an effect of preventing penetration of external moisture and pesticides at a mixing ratio of about 1: 1, Emulsifier at a mixing ratio of about 1: 1 to prepare a second mixed composition, mixing the first mixed composition and the second mixed composition at a ratio of about 1: 1 to prepare a third mixed composition, And a mixture obtained by mixing mugwort extract with the above-mentioned third mixed composition is coated with a coating roller on the surface of a paper material to prepare a fruit envelope.

The Applicant has found that in the applicant's preferred patent application No. 10-2011-0015311, edible oil, linseed oil, A method of preparing a fruit bag by mixing a composition prepared by mixing animal oil with petroleum at a weight ratio of 3: 1 and then mixing the mixture with emulsion, sulfur, wood vinegar and ginkgo biloba extract, Respectively.

However, in these prior arts, when manufacturing the fruit pouch, five drying rollers having a diameter of 1.5 m are usually used for drying at 150 ° C. In this case, drying time is long due to use of cooking oil, animal oil, petroleum, paraffin wax, Not only there is a difficulty in the process, but also these materials have a disadvantage in that they cause stains in the fruit, thereby deteriorating the commerciality of the fruit. Specifically, when cooking oil, animal oil, petroleum, or paraffin wax is used, only 80 m / minute can be dried.

Accordingly, the present inventors have conducted studies to solve these problems, and as a result, they have found that drying time can be remarkably shortened by using alcohol as a highly water-soluble solvent that does not use edible oil or animal oil, thereby completing the present invention .

The method of manufacturing a fruit bag according to the present invention is economical because the manufacturing process is shortened, and the fruit bag produced by the manufacturing method of the present invention can minimize or even minimize stains in the fruit.

Fruit bags are generally manufactured by pasting and joining coated inlay and outer ply, and the coating solution coated on inlay and outer ply is very important. This coating solution causes stains in the fruit.

The fruit bags according to the present invention consist of two layers, "inward" and "blanks " close to the fruit, and the coating liquid prepared according to the present invention is coated on both inks.

The method of manufacturing a fruit bag for insecticidal and insecticidal purposes according to the present invention generally comprises the steps of folding and folding a coated inlay and a coated outer layer, then peeling and joining the opposite edge of the folded outer edge, Attaching and cutting, and then pasting and joining the bottom edge.

Inlay and outer layer must be coated with a coating solution before pasting and bonding. To prepare the coating liquid, a water repellent agent mixture is first prepared by mixing paraffin wax, polyethylene wax, fatty acid amine and water. The water used should be pure water, ie pure water. The composition ratio of the primary mixture is as follows, based on the total of 100% by weight:

27 to 29% of paraffin wax,

6 to 8% of polyethylene wax,

1 to 2% of fatty acid amines, and

Water 64-66%.

The composition and composition ratio of the water repellent agent mixture in the present invention are the results obtained by repeated experiments several times.

Then, the water-repelling agent mixture obtained above is mixed with alcohol to prepare a second mixture, wherein the weight ratio of the water-repelling agent mixture to the alcohol is 3: 7. Of alcohol When the amount is used less than the above ratio, the viscosity becomes too high to be mixed, and when it is higher than the above ratio, coating on the coated paper becomes difficult.

Examples of alcohols that can be used in the present invention include methanol, ethanol, propanol, butanol, pentanol and the like, but methanol is preferred.

According to the present invention, the secondary mixture obtained above is mixed with the tertiary mixture to obtain a final coating solution, wherein the tertiary mixture is selected from the group consisting of cypermethrin, azoxy strobin, methyl propyl diglycol Propylene diglycol), methanol, soybean oil, ammonium polyoxyethylealkyl aryl sulfate and defoamer, and the composition ratio thereof is 100% by weight based on the following chemical composition:

5 to 10% of azoosistrobin,

40 to 50% of methylpropylene diglycol,

5 to 10% methanol,

2 to 3% of soybean oil,

3 to 5% ammonium polyoxyethylene alkyl aryl sulfate, and

Defoamer 3 to 5%.

The cypermethrin used in the present invention has an insecticidal action. When the amount of cypermethrin is out of the above range, insecticidal effect is not obtained.

In addition, the azoxystrobin used in the present invention has a sterilizing action. If the amount of the azoxystrobin is out of the above range, there is no germicidal effect aimed at in the present invention.

In addition, methylpropylene diglycol and methanol used in the present invention are used as a solvent.

In addition, ammonium polyoxyethylene alkylaryl sulfate is used as an emulsifier.

When the third mixture according to the present invention is produced, bubbles are formed at the time of mixing. When the bubbles are mixed, the mixture is not well mixed and the viscosity is lowered. Therefore, the defoamer used in the present invention is commercially available. Octanol, cyclohexanol, other higher alcohols, polyethylene glycol alkyl esters, and the like.

According to the present invention, it is preferable that the secondary mixture and the tertiary mixture are 3 to 4 parts by weight of the tertiary mixture per 100 parts by weight of the secondary mixture. If the above range is exceeded, mixing does not work well when coated on paper.

Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited thereto.
