Description

[Detailed Description of the Invention] This invention provides cyclized products of polyvinyl alcohol, urea,
Paints made from aldehyde condensation resins of melamine, aniline, and phenol with aromatic properties, luminous properties, and antibacterial and sterilizing properties can be used on metal products, processed products such as bamboo and wood, fish nets, paper, fiber cloth, glass products, etc. Aromatic, antibacterial, and insecticidal, characterized by being applied to ceramic, plastic, and rubber surfaces, drying, and curing by heat treatment at room temperature or high temperature to form a surface film on the object. The contents relate to the usage of photochromic paints.

For example, in the surface treatment of glass fibers, an aqueous solution of borane resin or silicone resin is applied to the surface of the glass fiber, which is then dried and heated to form a highly adhesive plastic film on the surface. It was processed to suppress formation and improve adhesion. The borane liquid of this resin was mainly made of chromium polyacrylate, and the latter was made of silane resin, that is, silicone resin. In addition, there is so-called butyral resin, which is made by adding butaraldehyde to polyvinyl alcohol and cyclizing it, as an adhesive for tempered glass.
In the past, many sheets of polyvinyl alcohol butyralized film were laminated onto glass plates to form tempered glass, which was used in automobiles and building materials. However, these methods are expensive, have low mold resistance, and have drawbacks, especially since they lack coloring and light-transmitting properties, and lack aesthetic features. In particular, when exporting glass products such as general cups, vases, and bottles, and when exporting lenses, etc., there was a drawback that mold was likely to grow. In addition, water sources may adhere to laminated glass or goldfish aquarium glass in which colored imitation paper is laminated to the surface of the glass plate, which may cause the kimono to lose its aesthetic appeal or have poor adhesion. There was a drawback. Instant adhesives made of cyanopolyacrylic acid resins and polyester resins are known as adhesives for general glass, but improvements have been sought since they are mold-proof and expensive.

In addition, in the processing of fishing nets, not only do oyster shells adhere to them, causing problems during operation, but also the seaweed-attached nets used for seaweed cultivation have the above-mentioned drawbacks, and dibutyl tin is added to the surface of these nets. It was used mixed with paint, but this caused seawater contamination and caused problems for human health, so there was a need to develop a process for making this antibacterial net harmless. In addition, bamboo products, wood, plastics, and metal products are used for the underwater stake rods that support this seaweed net, but bamboo and wood products are inexpensive, so their insect-proof and anti-bacterial properties are low. Dibutyltin paint has been used in all cases, but this also spreads to seawater contamination and fish contamination, causing hygienic problems and damage to the gills of fish.The concentration in the bodies of humans who eat it also increases, and this There was a need for the development of improved and harmless antibacterial agents.

In addition, as a metal surface coloring process, coloring of stainless steel spoons, knives, and especially aluminum processed products using electrolytic coloring resin is patented as an electrolytic coloring method by Harima Chemical Company, but this etc. is not exported. When packaged as a product in a humid region like Japan, mold tends to grow on the surface and the surface loses its luster, which is the subject of complaints. Similar problems have arisen in products such as bamboo brushes, ballpoint pens, and toys, as well as electrical products and mechanical products.

In particular, it maintains surface gloss for a long time on thin sheets, films, and molded products made of glossy stainless steel, nickel, chrome, cobalt, and ferroalloy used for building materials and plumbing sinks, and furthermore, the surface has a rainbow of colors. It has been difficult to process known paints to impart light-absorbing properties.

However, in order to increase the added value, decorative light-enhancing treatments were needed, especially for stainless steel surfaces, razors, knives, and other processed products for Europe and America. In addition, surface treatments such as the formation of an acid film by Parkerizing and nitroprusside have been known as anti-corrosion treatments for pig plate coils and cyclone films, but in both cases a black and glossy surface can be obtained. There wasn't.

In particular, antirust treatment using nitroprusside is carcinogenic, pollutes the atmosphere, and poses health problems for the human body.

In addition, many of the organic phosphorous agents, organic copper salts, thiocyanides, and chlorinating agents that are often sprayed on golf courses as pesticides are toxic and contribute to the death of microorganisms other than crops, and can harm fish and shellfish. Therefore, there was a demand for the development of harmless pesticides.

The present invention provides insect repellency by processing the metal bamboo, wood, ceramic, cement concrete glass products, tiles, etc.
Antibacterial properties are exhibited by retaining their aromatic properties, and this aromatic property is made into micro-encapsulated resin paints, which increases the effectiveness and sustainability of the disinfectant and creates resistant bacteria through its antibacterial properties. It not only suppresses the activity, but also provides rainbow-colored chromaticity and pearl pleochroism, as well as insect repellent and antibacterial properties for fishing nets and seaweed nets, and is also used as a surfactant in the surface treatment of plastics. , lactate calcium powder, silver salt, etc. were added, silicate jadeite powder and radiation calcium jadeite powder were impregnated with the aromatic antibacterial synthetic resin liquid, and the dried fine powder was placed on a plastic film for 10 to 20 minutes. % dispersed and melted to make a molded film bag, or applied to the inside or both sides of the film bag and laminated, and when used for packaging as a bag to maintain the freshness of vegetables, it will last for 5 to 30 days. It is now possible to maintain freshness by applying this aromatic antibacterial synthetic sap to fruits and fillers, or by spraying it on the leaves of plants, and by spraying a liquid containing Sierrac tree wax, parapine, and fatty acid surfactant. hand,
When added to soil, it exhibits antibacterial properties against Fusarium disease,
It is useful as a preventive measure against pollution, as it prevents the rooting of golf courses and prevents soil contamination.

In addition, this aromatic antibacterial agent can be added to beta, pinene drugs, and used to treat wastewater sludge and scum cake with calcium lactate and clo2.
When treated with a mixture of bacteria, lactic acid, urease, lipase, amylase, protease enzymes and yeast, it has the effect of deodorizing and suppressing bad odors. It is effective in preventing wastewater and scum cake from shochu factories and bad odors that pollute the air at feed factories.

In addition, these aromatic antibacterial resin liquids adsorbed on zeolite or bentonite or mixed with lime factory waste and dried can be used as a soil conditioner to prevent clubroot disease, which is a problem in continuous cropping, and can be used for Chinese cabbage and cabbage, It is useful as a prophylactic for sugar beet, potato carrot, etc.

Also, when spraying this aromatic, antibacterial synthetic resin liquid on fruits to prevent black spot on apples, it is recommended to spray the aromatic, antibacterial synthetic resin liquid applied onto apple wrapping paper bags to prevent adhesion and contamination with Fusarium disease spores. Microencapsulated synthetic resin liquid has the effect of maintaining durability for more than half a year, and the co-condensate of phenol and this polyvinyl acetal increases elastic strength, and when added to urea resin, it has excellent dryness resistance. It has the characteristic of being strong against water, and retains its aromatic and antibacterial properties for a longer period of time.

In addition, when applied to woven or non-woven fabrics, it not only has a deodorizing effect but also has antibacterial properties as a bedcloth or diaper cover, suppressing the generation of bad odors.

In addition, the wrapping paper impregnated with this aromatic and antibacterial synthetic resin liquid exhibits an anti-mold effect, inhibits the growth of E. coli, and in particular, the combined use of dyes may also increase bactericidal properties. In addition, medical instruments that have been treated with metal surfaces form an antibacterial film, and their disinfection and antifogging properties are improved by adding trace amounts of disinfectants such as monochloric acid and orthonitrophenol soda, as well as lactate. In addition, microcapsules containing a trace amount of nitroprusside, which not only gives off rainbow-colored light and increases product value but also improves the rust prevention properties of machinery, are 1/10th the amount of known nitroprusside used. It exhibits its rust prevention effect in the following conditions. In addition, this aromatic and bactericidal synthetic resin liquid with naphthalene dispersed or added with parasol, camphor, or cedar cypress oil can be applied to chests of drawers, desk drawers, etc. and dried to prevent pests from entering from outside. It exerts a repellent effect and has a useful life of more than 5 years by micro-encapsulating its aromatic content.

In order to further extend this service life, a material that is treated with a chromium arsenate, zinc-copper solution and impregnated with this aromatic antibacterial synthetic resin solution is used, which maintains its antibacterial properties for 10 years.

In addition, when applying the dried aromatic, antibacterial synthetic resin sol to trees or fruits that have been previously coated with polyacrylate sol or alginate soda sol using this aromatic antibacterial synthetic resin liquid as a curing agent, the former film will rapidly dissolve. It hardens and forms a protective film, which has the effect of preventing pests and bacteria from invading. Also aromatic,
After diluting and spraying an antibacterial synthetic resin sol, when a boric acid solution or a silicate solution is sprayed onto a dry surface, the solution rapidly undergoes acetalization and cyclization to form a cured film. To apply this aromatic antibacterial synthetic resin liquid to plastic, laurel sulfate or lauric acid ester liquid can be used, and it is best to wash and dry it. It is used as a pre-treatment for silver plating, and after plating, apply this liquid to the surface. When dried, it maintains a shiny surface for a long time and exhibits an iridescent color, making it useful as a protection for other metal-plated or vapor-deposited surfaces. In addition, a pigment dye, an insecticide pyrethroid, an elasticity fragrance agent butylene glycol, etc. are dispersed in this aromatic antibacterial synthetic resin liquid, and this is mixed with stone powder, poured into a paper incense stick, dried, or made with sawdust. The powder impregnated removes the pungent odor of the paper and functions as an incense stick.The thermal decomposition of the insecticide is reduced to one third of that of conventional kneaded pyrethrum incense sticks, and orthonitrophes are used to control this combustion. When nor soda or piuriric acid is used, it always burns a whitish-gray color, making it useful as an incense material.Iodine salt added to prevent pandosi disease can be used to prevent iodine in sheep and domestic animals. It is used as a fog method to diffuse and absorb it, and it is also used as an insect repellent for poultry, pigs and cattle.

In addition, bleached jute fibers and aluminum salts of ammonium citrate, formic acid, tartaric acid, and lactic acid are coated and impregnated with the synthetic resin liquid made of the aromatic antibacterial alloy in organic acid ammonia salt water.
Dried products have fire retardant properties and aromatic properties, and those coated with small amounts of parapine chloride, antimony oxide, silicates, etc. have the effect of increasing fire retardant properties. The fire-resistant surface of the veneer plywood coated with this material is 800℃, and the fire resistance is 30℃.
It has the characteristic of not burning for more than a minute.

This organic acid aluminum is made by extracting bentonite or boxide powder with an organic acid and mixing it with ammonia salt.

In addition, when the present aromatic antibacterial synthetic resin liquid is adsorbed on perlite, pumice stone, or fired mica stone and used as a deodorizing agent, it is useful as a water solvent, toilet deodorizing agent, interior deodorizing agent, and car interior deodorizing agent.

The implementation of this invention will be explained with reference to the drawings as follows.

In the figure, low-polymerized polyvinyl alcohol 500% powder is introduced into the autoclave (1) from the tank (3), water is added from the pipe (6), and while stirring with the stirrer (2), 800% of the powder is introduced into the autoclave (1). Heat to above ℃ to make a 20% solution of polyvinyl alcohol.

This is sucked with a gear pump (72) and placed in an autoclave (
A sol dissolved in 8) is introduced, and while stirring with a stirrer (9), the sol temperature is lowered to 30° C., and a plurality of aldehyde solutions are introduced from a tank (92), mixed well, and reacted. Next, the sol is introduced into the liquid vats (14) and (14') of the coating machine through the pipe (11) from the pump (112) to the pipe (13), and the coating rolls (15) and (15') are used to coat the fiber cloth. paper (16)
is sandwiched between rolls (15) (15') and coated. Next, this coated fiber cloth and paper (16') are introduced into a drum dryer (16b) and heated, and the fan (16') is heated.
While drying in a) and winding up with a winder (17) to coat the aromatic antibacterial synthetic resin liquid sol, the adsorption medium is transferred from the pipe (11) to the mixer (18) and from the tank (20). The sol introduced from the pipe (11) was mixed, and this mixture (A) was put into the saucer (22), and the mixture in the saucer was conveyed to the dryer (24) by the comparer (23). is dried, weighed and packaged using a packaging machine (26), and processed into powder or granules to be commercialized.

In addition, the sol introduced from the autoclave (8) through the pipe (10) is bottled or canned by the filling machine (25) and commercialized as a sol.
Dilute it 5,000 times and sell it as Resmin.

The powder is dried and processed into a packaging bag (27).
A) is made by masticating molded plastic pellets with a two-stage rolling roll (28), heating and melting the plastic at 180°C, and extruding white or colored powder in which the sol dry powder is dispersed using a Daruma extruder (29). Cut with pellet cutter (30) to make pellets. The pellets (c) are introduced into an extrusion heating machine (31), processed into a film (34) through a nozzle (33), and wound into a roll using a winder (35) to make a freshness-preserving bag. , produce freshness preservation bags (d) for vegetables and fruits.

FIG. 2 shows a plan view of this freshness-keeping bag (d), in which the aromatic, antibacterial, and radiation-active calcium lactate is dispersed and mixed inside the plastic film (d') of this freshness-keeping bag (d). ing. Inside the bag (d), polyvinyl and polyacrylic acid soda paper are inserted together with a moisture absorbing bag (g), and the Matsutake mushroom (e) to be packaged is placed and wrapped, and the bag (d) ) is provided with perforations (f) as necessary.

When used in combination with an ice pack, this perforation (f) is not necessary, and vacuum packing is generally used for this packaging. Freshness is maintained for 10 days, whereas with this kind of packaging, freshness is maintained for only 3 days.
When kept in a refrigerator at 8°C, less than 30% of the products fermented and spoiled in 20 days. Apple bags mixed with 10% powdered aromatic and antibacterial synthetic resin stone powder in polyethylene bags had the effect that the sugar content did not change after 15 days, with the sugar content of 14 remaining unchanged, and the sugar content of 9 remaining unchanged for 30 days. . The stone powder used had 1.2 to 1.4 times the natural radioactivity, but when using matsutake mushrooms and fresh shiitake mushrooms, the radiation properties were reversed and the results were poor.

In the case of matsutake, the stone powder impregnated with an aromatic and antibacterial synthetic resin containing salicylic acid ester gave good results, but the results were better with calcium monochlorate, and the stone powder mixed with orthonitrophenol soda gave better results. The results were good.

Figure 3 shows silicate zeolite, pentonite, and pumice powder (
A pest repellent powder having the aromatic antibacterial synthetic resin coating (i) encapsulated on the surface of h), which is used by mixing it with a soil conditioner. For this purpose, a material whose radiation property is 1.2 to 2.5 times that of natural radioactivity is used. This zeolite pumice powder uses powder particles of 100 to 30 mesh, and is made by pulverizing anhydrite using a pulverizer and diluting an aromatic and antibacterial synthetic resin sol 100 to 2000 times with water. Spray it to a concentration of ~20%, dry it, and use it as a powder.

Since the solvent is alcohol, it dries quickly, and is used in paper incense sticks and as a coating agent for insect repellent paper on apples and tangerine fruits. Example (8) is used as a coating agent on the surface of paper incense sticks, and is applied to jute fiber string incense sticks, bamboo sticks, and linear cotton to be used as combustion bodies.

Note that if an alcohol solvent without water or a paint dissolved in an alcohol-hexane solvent is applied, the drying time will be reduced to one-tenth.

Example (9) is a contact lens, which can be made by dissolving polyvinyl alcohol in warm water, pouring it into a plastic mold or glass mold, adding aldehydes and stirring, or dissolving it at a low temperature of 30°C. The product is poured into a mold to gel, and the insoluble product is removed from the mold, immersed in distilled water, and stored in a plastic storage bag. These contact lenses are used for 20 to 30 days and are replaced each time. The refractive index is almost the same as polyester, chitin, and polyacrylate.

The special feature of this contact lens is that it contains aldehyde, an antibacterial agent, so it not only has an anti-mold effect and suppresses the growth of E. coli and cocci, but also has elasticity and high adhesion to the eyeball, so it does not come off easily.

67p.
p. b was the highest value, and water pollution was 17p. p. It was b. This was about 3.9 times the normal level of contamination, but when an aldehyde aqueous solution dissolved in polyvinyl alcohol is used, for example, in the formulation of Example (4), an equal amount of this simadine is dissolved and adsorbed to the stone powder. The degree of contamination dissolved in wastewater is reduced to one-thirtieth. Since this is a polyvinyl acetal, its solubility is low, and CAT is dissolved in a 5% solution of sodium alginate water and dispersed in the aromatic antibacterial synthetic resin solution.
Immediately microencapsulated had even less solubility. Also, flutolanil, isopthiolane, DD. V. P. Similarly, when mepronil, sumithion, atradine, naprobamine, and diazinon are microencapsulated, their solubility is reduced to 1/20th or less, so wastewater pollution at golf courses is improved compared to conventional methods. For example, diazinon, which was 1.4 times more contaminated, was reduced to 1/20th. Diazinon microencapsulated in an aromatic antibacterial synthetic resin was sprayed onto the grass surface and exposed to sunlight.
Due to photosynthesis, insolubility progresses and solubility decreases, which is considered to be due to the progress of cyclization of polyvinyl alcohol.

In addition, when a dispersion of parapine stearic acid, hydrogenated oil, lauric oil, and ceramic pine resin dispersed in a surfactant and an organic solvent is added to this aromatic and antibacterial synthetic resin liquid, those that are sprayed on the turf surface are , the hydrophobicity becomes higher, and the runoff property against rain falls. This was due to microencapsulation, which resulted in finer particles.

The adhesion of the grass surface against this rain is that if it is exposed to sufficient sunlight on a sunny day, the antibacterial vanillin, cinnamic acid, and protocatechualdehyde will be microencapsulated and will remain in the synthetic resin for three months. Retained. Bamboo products and wooden products coated with this aromatic and antibacterial synthetic resin contain 6 cinnamic aldehyde (cinnamaldehyde), 12 black mold, 25 Staphylococcus aureus, 12 microbacilli, and 25 Pseudomonas genus. and for vanillin, 10, 20, 30, 10, 10, 10
, and for protocatechualdehyde they are 10 and 10, respectively.
20, 30, 10, 30, 30. For benzaldehyde, 360, 350, 500, 225, 20, respectively.
It becomes 0.500, and the bactericidal property decreases, but when a mixture of cinnamic acid aldehyde and vanillin protocatechualdehyde is used, it becomes 6, 10, 20, 3, 10, 25.

In particular, since cinnamic acid aldehyde, benzaldehyde, vanillin, etc. are harmless, radiation, calcium carbonate adsorbs this aromatic antibacterial synthetic resin, and drying with Tanachi (Sanshichi) sodium tungstate added. When used as a toothpaste, it is effective against mold, gram-positive bacteria, and gram-negative bacteria, especially soil bacteria, but the latter is more effective against bacteria, and the addition of monochloroacetic acid is effective against bacteria. In contrast, antibacterial control is further strengthened. When organic mercury or organic copper is added to this, the bactericidal properties are increased and salicylaldehyde also has bactericidal properties with 25, 125, 125, and 25125 125, respectively.

Also, this aromatic antibacterial synthetic resin with orthonitrophenol soda added is useful for preserving fish, meat, and meat, and can be applied to or directly applied to Styrofoam boat containers.
Products to which lactic acid has been added are effective in preventing deterioration for 10 days even if left at 25°C. Furthermore, adding lactic acid to this aromatic antibacterial synthetic resin sol in soil has the effect of preventing clubroot, controlling Fusarium bacteria, and preventing spore transfer.

When using organic acid copper to prevent root rot, microencapsulating it with this aromatic antibacterial and synthetic resin not only reduces wastewater contamination to one-twentieth, but also reduces the amount of copper used to one-tenth. If iron salts are used in combination, the toxicity will be further reduced. In addition, a reactor for alcohol fermentation in which yeast is cured with this aromatic and antibacterial synthetic resin has twice the durability of a general calcium alginate reactor.

Generally, the reaction between benzaldehyde and polyvinyl alcohol is performed by adding 0.5 g of polyvinyl alcohol to 10 cc of solvent.
Mix with a certain amount of hydrochloric acid, seal, shake, react at constant temperature, add alkali to neutralize the catalyst hydrochloric acid, precipitate the target product, and wash well with methanol. 67
Dry in a dryer at 5°C. In this case, 3.5 equivalents of benzaldehyde are required to reach a degree of acetalization of 60%, and the rate of acetalization becomes constant over 5 hours. Ethylene chloride is used as this solvent, but when hydrochloric acid is used at a concentration of 0.01N and 5 times the equivalent of benzaldehyde is used, the degree of acetalization reaches 83%, which is comparable to benzol and tetralin. It becomes soluble and swells in ethyl acetate and acetone. Also, the softening point is 120
˜150° C., higher values are obtained with O-chlorobenzal. In addition, acetalization with aminoaldehyde ethyl acetal is as follows. Also, reacting polyvinyl alcohol with a ketone to form an acetal is similar to the reaction with benzoalhyde described above. An acetalization degree of 70% in this reaction is easily produced, and ethylene, chloride benzene, toluene, xylene, tetralin, chlorinated benzene, pyridine, and carbon tetrachloride are dissolved, but it is insoluble in acetone, and its softening point is is 147°C, and the molecular structure of this reaction of cyclohexanone acetal, which is equivalent to polyvinylbenzal, is as follows.

Also, when polyvinyl alcohol is converted to polyvinyl acetate and reacted with butyraldehyde using methanol as a solvent, when the water content in methanol is 0, the degree of acetalization is 1/9 of 53.6%. Anything that contains water,
It rose to 59.7% and at 3/7, it reached 0.2% and 1
:1, on the other hand, it decreases to 50.9%, but many have acetic acid groups attached. To react with acetaldehyde, the acetalization of polyvinyl acetate with acetaldehyde in methanol is performed using polyvinyl alcohol at a concentration of 10.5%, 2 times the equivalent of acetaldehyde (para-altehyde), HLSOα 0.5 MOL/l deacetic acid 608, 40 When the acetalization temperature is 60° C., the degree of acetalization is 25.5% in 1 hour, 41.3% in 2 hours, and 45% in 24 hours. This degree of acetation is 3
7.8%, 32.4%, and 1.9%. This reactant is soluble when the ratio of acetone, chloroform, methyl acetate, ethyl methanol, butanol, ethanol and water is 7:3, and it dissolves when heated when ethanol or ethanol water is 5:5.

Alternatively, to acetalize polyvinyl acetate with butyraldehyde, there is a method in which hydrochloric acid and butyraldehyde are added, acetic acid is removed by ester conversion, and at the same time, butyralization is performed. For example, polyvinyl acetate 0.368MOL
/l butyraldehyde 0.525MOL/l, Hcl
0.156MOL/l, reaction temperature 60℃, reaction time 60
For minutes, deacetic acid degree 12.6% MOL/% 200 minutes 33
．． At 9% and 500 minutes, it becomes 67.8%, and at the butyralization degree MOL/% at 60 minutes, 1.6% becomes 7.6% at 200 minutes, and 45.5% at 500 minutes. When this butyral is treated at high temperature, it becomes insoluble in chloroform and ethanol, and when it is heated, it becomes soluble in a 7:3 ratio of ethanol to water. The degree of acetalization decreased from 65.2% to 54.6%. However, if this substance is further converted to butyral, it becomes soluble in chloroform and ethanol, and if the hot water is made alkaline, it does not become soluble. This is probably because sulfuric acid is liberated at high temperatures when butyral is bound to sulfuric acid. In general, in acetalization, the lower the alhyde content, the faster the time for dissolution.

However, as in the present application, in order to increase the aromatic properties, the acetal ratio is generally lowered to 60% or less, and to increase the antibacterial property, even when the acetal ratio is set to 70%, there is no difference. I have no support.

It is also possible to use an acid as a catalyst in acetalization, but if there is residual acid, it cannot be used to maintain freshness.

As mentioned above, the feature of the present invention is that instead of cyclizing with the conventional acetalized resin for vinylon fiber processing, that is, formaldehyde or ultra pin agent, less toxic benzaldehyde, cinnamaldehyde, vanillin, safrole, etc. etc., the ingredients that do not harm the human body, plants, or animals are dispersed in a resin sol and microencapsulated, so there is no pollution when sprayed on animals and plants, and it exhibits antibacterial properties, and is exported. It exerts a mold-proofing effect on miscellaneous goods, improves complaints, and facilitates rainbow coloring and electrolytic dyeing of metals.By adding a decorative surface, it has the effect of increasing the load value of the product, and can also be used to maintain freshness. It is useful for preventing clubroot disease, and as a soil improvement agent, radiation powder impregnated with silicate powder such as zeolite, bentonite, pumice, etc., with the addition of lactic acid bacteria, alcoholic yeast, cellulase, etc., is fixed. Mixing 150 kg of powder per 1 soil with 700 kg of organic fermented fertilizer can suppress continuous cropping damage and enable the use of 3 to 5 solids. In particular, mixing chitin-chitosan powder and main straw can reduce return yield. It increases by 30%.

In addition, dried meal powders made by impregnating freshness-preserving plastic film bags or containers with this aromatic antibacterial synthetic resin, especially Radiesin ■, have improved freshness retention and can be used for fruits and vegetables and can be kept for more than 5 days. became. Paper coated with this synthetic resin is also useful as a base material for making cotton incense, and the paper that has been absorbed into fibers is used as interior goods.
When used in medical equipment, it improves sterilization properties, making it extremely hygienic.It increases the durability of bamboo products and stakes for fishing rods by 10 times, and when applied to nets, it reduces harmful dibutyltin. It has the advantage of improving dissolved contamination through micro-encapsulation, is made by curing inexpensive contact lenses, is elastic, has disinfectant properties, and is used as a deodorizer to purify the air in toilets, rooms, and cars. It is also effective in deodorizing the inside of the refrigerator.

Therefore, the aromatic antibacterial synthetic resin of the present invention, which is non-toxic, can be used as a spraying agent and as a material for forming glossy antibacterial films on chocolates and fresh sweets.

As shown above, polyvinyl and alcohol with an acetalization rate of 60% or less are used, but for highly toxic substances such as pesticides, or to increase water resistance, the acetalization rate should be 70% or less. For those with 80% or more, combined dispersion or
It is used as a surface coating material, as an elastic material for phenol and melamine aniline, and as a water and heat resistant material.
Also, when used for contacts and lenses, those with a high water content are less likely to cause damage to the eyeballs.Also, as an acetalizing agent for polyvinyl alcohol, cyclohexanone is reacted with cinnamon. aldehyde(
cinnamaldehyde) or benzaldehyde and vanillin dissolved in an organic solvent such as alcohol. It can also be used as a used paint. In this way, aldehydes are toxic. Acetalized products such as harmless benzaldehyde, cinnamaldehyde, and vanillin are useful for improving soil, preserving the freshness of fish and livestock meat, and as antibacterial agents, and are an industrially effective invention.

In particular, it is widely used not only as an anti-mold paint for miscellaneous goods exported from our country, but also as a rust preventive agent. too. When nitroprusside, which is commonly used as a highly toxic rust inhibitor, is encapsulated with this resin, its toxicity is reduced and the antibacterial properties have the effect of suppressing the acceleration of corrosion caused by bacteria.
