Description

Technical Field

[0001] The invention relates to the technical field of adhesives for trapping pests, and in particular to an aerosol-type insect-catching self-spraying adhesive and a preparation method thereof. Background Art

[0002] With the progress of society, people's lifestyles have changed dramatically. Whether in commercial places or ordinary families, the demand for cleanliness and hygiene is growing. A clean environment not only symbolizes health, but also provides pleasant sensory enjoyment. In maintaining a clean and hygienic environment, the prevention and control of common pests such as flies, fruit flies, and cockroaches has become an issue that cannot be ignored. Flies, fruit flies, cockroaches and other common pests in daily life have many commonalities, such as the ability to spread a variety of diseases and contaminate food and the environment. However, due to their sensitivity and strong reproductive ability, they are difficult to eliminate and their rampant problem has long plagued people.

[0003] There are two mainstream pest control products: insecticides and insect traps. However, both products have certain limitations. Among them, insecticides can kill pests such as flies more effectively, but long-term exposure or improper use of these insecticides may cause human health problems, such as respiratory diseases, allergic reactions, and even more serious chronic diseases; while insect traps have relatively minor effects on humans and the environment, but during use, it is not convenient overall. As a disposable product, insect traps need to be purchased and replenished frequently.

[0004] Therefore, it is necessary to provide a new insecticide product that can effectively trap insects, is easy to use, and can reduce potential harm to the human body and the environment. Summary of the invention

[0005] In order to further improve the comprehensive performance of insecticide products, so that insecticide products can not only effectively trap insects, but also be convenient to use and reduce potential harm to humans and the environment, the present application provides an aerosol insect-catching self-spraying glue and a preparation method thereof. The aerosol insect-catching self-spraying glue of the present application, through a specific formula design, achieves effective trapping of pests, while ensuring the safety and convenience of the use process, providing people with a new, efficient and safe pest control product.

[0006] In the first aspect, the present application provides an aerosol insect-catching self-spraying glue adopts the following technical solution: An aerosol insect-catching self-spraying glue comprises the following components in parts by mass: 50-90 parts of a solvent, 5-10 parts of an adhesive, 4-9 parts of a terpene resin, 3-8 parts of a rosin glycerol ester, 2-5 parts of polyisobutylene, 1-3 parts of isobutylene stearate, 2-10 parts of polydimethylsiloxane, 0.5-5 parts of a trapping flavor, 0.1-5 parts of an antioxidant, and 0.1-0.5 parts of a preservative.

[0007] In the above technical scheme, by adding solvents and adhesives, it is ensured that the glue of the aerosol insect-catching self-spraying glue has good adhesion properties; by the compound use of terpene resin and rosin glycerol ester, the viscosity of the glue is significantly enhanced, and at the same time, the adsorption effect of the glue on paper or other media is improved, thereby increasing the breadth and applicability of the aerosol insect-catching self-spraying glue; by the introduction of polydimethylsiloxane, the glue is given a certain hydrophobicity, and the ductility and defoaming properties of the glue are improved, thereby reducing the influence of the environment on the viscosity of the glue, so that after the glue is sprayed out, a layer of uniform insect-catching adhesive film can be quickly formed, effectively covering a larger area and improving the insect-catching efficiency; by the use of polyisobutylene and isobutylene stearate, not only the stability and durability of the glue are increased, but also the volatilization rate of the glue can be reduced, and the volatilization of the solvent can be inhibited. At the same time, the addition of polyisobutylene and isobutylene stearate can reduce the effect of polydimethylsiloxane on the adhesive strength and enhance the catching strength of the insect-catching adhesive film; the addition of trapping flavors further enhances the attraction of the aerosol insect-catching self-spraying glue to different types of pests, making it easier for pests to adhere; at the same time, terpene resin, rosin glycerol ester, polyisobutylene and isobutylene stearate have a synergistic effect with the trapping flavors, which is beneficial to improve the fragrance persistence of the aerosol insect-catching self-spraying glue, prolong the fragrance retention time of the trapping flavor, and increase the durability of the product; the use of antioxidants and preservatives ensures the stability of the aerosol insect-catching self-spraying glue and prolongs its storage time, reducing the performance degradation caused by oxidation and microbial action.

[0008] Preferably, the following components are included in parts by mass: 65-75 parts of solvent, 7-8 parts of adhesive, 5-8 parts of terpene resin, 4-6 parts of rosin glycerol ester, 2-4 parts of polyisobutylene, 2-3 parts of isobutylene stearate, 4-8 parts of polydimethylsiloxane, 1-3 parts of trapping flavor, 0.1-1 parts of antioxidant, and 0.1-0.25 parts of preservative.

[0009] Preferably, the following components are included in parts by mass: 69 parts of solvent, 8 parts of adhesive, 6 parts of terpene resin, 5 parts of rosin glycerol ester, 3 parts of polyisobutylene, 2 parts of isobutylene stearate, 5 parts of polydimethylsiloxane, 1.5 parts of trapping flavor, 0.3 parts of antioxidant, and 0.2 parts of preservative.

[0010] In the above technical scheme, by further optimizing the dosage of each component of the aerosol insect-catching self-spraying glue, the aerosol insect-catching self-spraying glue has better adhesion performance and stability, further improving the trapping efficiency and ease of use of pests.

[0011] Preferably, the adhesive is styrene-butadiene rubber.

[0012] In the above technical solution, by selecting styrene-butadiene rubber as the adhesive, styrene-butadiene rubber has good adhesion performance and weather resistance and can adapt to different environmental conditions, thereby ensuring that the aerosol insect-catching self-spraying glue can maintain a stable adhesion effect in various climates and temperatures.

[0013] Preferably, the adhesive is a mixture of styrene-butadiene rubber, ethylene-propylene-diene rubber and ethylene-vinyl acetate copolymer in a mass ratio of (3-5): (1-3): (1-2).

[0014] In the above technical solution, by selecting styrene-butadiene rubber, EPDM rubber and ethylene-vinyl acetate copolymer as adhesives and mixing the three in a specific mass ratio, the adhesion performance and durability of the aerosol insect-catching self-spraying glue can be further improved. The combination of styrene-butadiene rubber, EPDM rubber and ethylene-vinyl acetate copolymer can not only provide excellent adhesion effect, but also maintain good stability and durability under different temperature and humidity conditions. The use of this mixed adhesive makes the aerosol insect-catching self-spraying glue more reliable in practical applications and can adapt to various complex environmental conditions.

[0015] Preferably, the solvent is a mixture of cyclohexane and dipropylene glycol methyl ether in a mass ratio of (90-95):(5-10).

[0016] In the above technical solution, by selecting cyclohexane and dipropylene glycol methyl ether as solvents and mixing them in a specific mass ratio, the stability of the aerosol insect-catching self-spraying glue can be ensured. Among them, cyclohexane has a lower volatilization rate, which helps to maintain the stability and uniformity of the spray, while dipropylene glycol methyl ether has a faster volatilization rate, which helps to quickly form a sticky insect-catching film. The use of this mixed solvent not only ensures that the spray can quickly form a stable sticky insect-catching film, but also ensures the durability of the sticky insect-catching film, prolongs the drying time of the sticky insect-catching film, and prolongs the use time of the sticky insect-catching film.

[0017] Preferably, the preservative is sodium benzoate.

[0018] In the above technical solution, sodium benzoate, as a commonly used preservative, can effectively inhibit the growth of microorganisms, prolong the shelf life of the product, and ensure the aerosol insect-catching self-spraying glue Preferably, the antioxidant is BHT antioxidant.

[0019] In the above technical solution, the BHT antioxidant has good antioxidant properties and can effectively prevent the performance of the aerosol insect-catching self-spraying glue from deteriorating due to oxidation during storage and use, thereby ensuring the stability of the aerosol insect-catching self-spraying glue and extending its use time.

[0020] In the second aspect, the present application provides a method for preparing an aerosol insect-catching self-spraying glue using the following technical solution: A method for preparing an aerosol-type insect-catching self-spraying glue comprises the following steps: Step 1: sequentially adding adhesive, terpene resin, rosin glycerol ester, polyisobutylene, isobutylene stearate, polydimethylsiloxane, trapping flavor, antioxidant and preservative into the solvent, stirring and mixing evenly to obtain a glue solution; Step 2: put the glue liquid into a spray can, seal it and then fill it with nitrogen to obtain an aerosol insect-catching self-spraying glue.

[0021] In the above technical scheme, the present application can prepare the glue liquid through the above simple preparation process, and then simply fill the glue liquid with nitrogen to obtain an aerosol-type insect-catching self-spraying glue. It can be seen that the preparation method of the present application is simple to operate and easy to mass produce.

[0022] In the third aspect, the present application provides a method for using an aerosol insect-catching self-spraying glue, which adopts the following technical solution: A method for using an aerosol insect-catching self-spraying glue, comprising: spraying the aerosol insect-catching self-spraying glue evenly on a flat paper, plastic film or other suitable surface, to form a thin and uniform insect-catching adhesive film. When using, just place the paper or film sprayed with the insect-catching self-spraying glue in an area where pests often appear. Since the insect-catching adhesive film has good adhesion and trapping effect, pests will be adhered to the adhesive film once they come into contact with it, thereby achieving the purpose of preventing and controlling pests.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The aerosol insect-catching self-spraying glue of the present application is compounded with terpene resin and rosin glycerol ester, and further added with polyisobutylene and isobutylene stearate, so it has better adhesion performance, stability and durability, can effectively improve the efficiency of trapping pests, and reduce the damage of pests to crops and home environment.

[0024] 2. The aerosol insect-catching self-spraying glue of the present application introduces polydimethylsiloxane, which gives the glue better ductility and further prolongs the drying time of the glue, so that the insect-catching adhesive film formed after the glue is sprayed out can cover a larger area and does not dry for a long time, thereby improving the insect catching efficiency; at the same time, the present application reduces the effect of polydimethylsiloxane on the adhesive strength and enhances the catching strength of the insect-catching adhesive film through the use of polyisobutylene and isobutylene stearate.

[0025] 3. The present application significantly improves the persistence of fragrance by adding trapping essence, and by adding four specific ingredients, namely, terpene resin, rosin glycerol ester, polyisobutylene, and stearic acid isobutylene, making it easier for pests to adhere, thereby improving the trapping effect.

[0026] 4. This application ensures good adhesion, stability and durability of the adhesive by selecting a combination of styrene-butadiene rubber, EPDM rubber and ethylene-vinyl acetate copolymer as the adhesive. DETAILED DESCRIPTION

[0064] Performance Testing Test 1: Test the viscosity of the aerosol insect-catching self-spraying glue at 25°C. The test results are shown in Table 2.

[0065] Test 2: Test the fly catching effect of the sticky insect-catching film made of aerosol insect-catching self-spraying glue: The aerosol insect-catching self-spraying glue of Examples 1 to 7 and Comparative Examples 1 to 4 were quantitatively and evenly sprayed on one side of a cardboard with a specification of 30cm*15cm to prepare a test sample, and the test sample was placed in a 37°C constant temperature box. After being stored for 0 days, 3 days, 6 days, and 9 days, the test sample was taken out to observe the state of the glue surface and whether the glue surface was dry, and the test was carried out. During the test, 100 adult flies (male and female) 3 to 4 days after eclosion were released into a glass simulated scene (3m*3m*3m) through the insect hole. At 25°C and a relative humidity of 50%, after the test flies resumed normal activities, the test sample was placed in the simulated scene, and after waiting for 5 hours, the test sample was taken out and the number of flies caught was counted. The test results are shown in Table 2.

[0066] Table 2: Combined with the analysis of Examples 1 to 7 and Comparative Examples 1 to 4, the viscosity of the aerosol insect-catching self-spraying glue of Examples 1 to 7 was maintained at a good level at 25°C, and after being stored in a constant temperature box at 37°C for 0 to 9 days, the glue surface did not dry out, and had a good fly catching effect from the 0th day to the 6th day, and the fly catching rate reached 90% or more, which shows that the aerosol insect-catching self-spraying glue of Examples 1 to 7 has good stability and insect catching effect, and has a long effective use time.

[0067] Specifically analyzing Example 1 and Examples 6-7, Example 6 used styrene-butadiene rubber as an adhesive, Example 7 used styrene-butadiene rubber and EPDM rubber as adhesives, and Example 1 had good viscosity and good fly catching effect. It can be seen that the adhesive compounded with styrene-butadiene rubber, EPDM rubber and ethylene-vinyl acetate copolymer can further enhance the adhesion effect, stability and durability of the aerosol insect-catching self-spraying glue.

[0068] Specifically analyzing in combination with Example 1 and Comparative Examples 1-4, Comparative Example 1 uses rosin resin to replace terpene resin, Comparative Example 2 uses rosin pentaerythritol ester to replace rosin glycerol ester, Comparative Example 3 uses polybutene to replace polyisobutylene, and Comparative Example 4 uses isopropyl acrylate to replace isooctyl octadecanoate. In comparison, Example 1 has good viscosity and good fly catching effect, and the adhesive surface of Example 1 still does not dry up on the 9th day. These replacements lead to a decrease in viscosity at 25°C and drying of the adhesive surface when stored in a constant temperature box at 37°C. This shows that the four ingredients of terpene resin, rosin glycerol ester, polyisobutylene and isooctyl octadecanoate used in this application are crucial to improving the viscosity of the aerosol insect-catching self-spraying glue and maintaining the stability and insect-catching effect of the aerosol insect-catching self-spraying glue. This application uses a compound of terpene resin, rosin glycerol ester, polyisobutylene and isobutylene stearate to improve the viscosity of the glue, further extend the drying time of the glue, improve the stability of the glue, and make the fragrance of the trapping essence more lasting, thereby improving the long-term trapping effect of the aerosol insect-catching self-spraying glue on flies.

After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
