Problems solved by technology

[0003] There are three main hazards of this kind of storage beetle: they feed and cause direct weight loss; feeding, excretion, molting, corpses, etc., affect the color, aroma, and taste of food, resulting in quality loss; simultaneous excretion, heat production and other reasons cause mold grow, mildew
Moreover, storage beetles are sensitive to light, but the environment where they live often cannot add additional trap lights, which greatly reduces the efficiency of trapping insects.

Embodiment 1

[0038] The preparation method of viscose:

[0039] (1) 50 parts of 4,4-diphenyl diisocyanate are dissolved in ethyl acetate, join in the there-necked flask, be added dropwise in the bisphenol A diglycidyl ether of 45 parts; dropwise temperature is controlled at 60 ℃, after complete dropwise addition, react for 1 h, and cool; the molecular weight of bisphenol A diglycidyl ether is 4000-5000.

[0040] (2) 1 part of rosin ester, 2 parts of ethylene glycol and 0.2 part of antioxidant tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid]pentamyl alcohol ester were added to the above reaction In the liquid, react at 100 °C for 1 h, and stir for 10 minutes to obtain a basic liquid glue;

[0041] (3) After dissolving 0.1 part of the fluorescent whitening agent Q4 in ethyl acetate, it was added dropwise to the basic liquid glue, and the reaction was kept at the temperature for 10-20 minutes to obtain a fluorescent liquid glue.

[0042] Apply the above colloid to figure 1 The...

Embodiment 2-6

[0044] According to the preparation method of Example 1, the components and corresponding contents of Examples 2-6 in the following table were used to prepare viscose, and the viscosity of the obtained viscose was in the range of 130-150 mPa.s / 180°C.

[0045] Similarly, the preparation method of Example 1 was used, and the adhesives of Comparative Examples 1 and 2 were prepared according to the components and contents of Comparative Examples 1 and 2.

[0046]

[0047]

[0048] Insect trapping effect test

[0049] The viscose obtained in the embodiment is evenly coated in the insect trapping box, and it is placed in the corner of the house. After 24 hours of trapping insects, the effect of trapping insects in the insect trapping box is as follows. Figure 4 and Figure 5 shown, where Figure 4 It is the insect trapping effect diagram of viscose in Example 5, and its insect trapping effect is good; Figure 5 It is the insect-catching effect diagram of the viscose of Com...

Embodiment 7

[0050] Example 7 Spectral Reflection Test

[0051] After respectively applying the viscose in Example 5 and Example 6 to the inner surface of the insect trapping box, and irradiating it with a light source, measure its reflectance. The viscose has obvious spectral reflection at 300-450nm, so the viscose can be Improve the insect trapping effect of glue without special setting of trap lights. The test results are provided by Shanghai Microspectrum Chemical Technology Service Co., Ltd. figure 2 For the test results of Example 5, attached image 3 It is the test result of Example 6.

Abstract

The invention discloses a fluorescent adhesive for luring insects and a preparation method thereof, and belongs to the technical field of adhesive insect catching. The adhesive can enhance the 300-550nm wave spectrum in reflected light, and the light with the wavelength correspondingly captures different types of insect pests, so that the insect catching effect of the adhesive is improved under the condition that an insect trapping lamp is not specially arranged. When the irradiation light source irradiates from natural light to an electrical light source, insect pest luring of the corresponding spectrum can be completed through the trapper or the trapping sticky plate smeared with the glue. Any light source can enhance the sticky trapping effect of the trapper by smearing the glue to trap different kinds of pests; and the adhesive is not only suitable for storing beetles, but also suitable for indoor and outdoor flies, mosquitoes and winged insects and winged insect crawlers in the forest and fruit industry.

Description

technical field [0001] The invention relates to a fluorescent viscose for insect trapping and a preparation method thereof, belonging to the technical field of viscose insect trapping. Background technique [0002] Storage beetles are all over the world, they have many species, wide distribution, small hard body, good walking, and have the biological characteristics of negative light. There are more than 50 kinds of storage pests in my country. The most common storage insect pests of beetles are codling beetle, red grain thief, saw grain thief, big grain thief, corn weevil, mung bean weevil, pea weevil, and corn weevil. Beetle mainly damages the embryo of rice, paddy, wheat, corn and other grains, loses germination rate, destroys packaging, and causes other warehouse pests to invade. The red grain thief is an intermediate grain storage pest between the early pests and the later pests. Worldwide distribution, except Tibet, all provinces, municipalities directly under the ce...
