Preparation method of insect lure adhesive
A technology of insect and sticky agent, which is applied in the field of preparation of insect attractant, can solve the problems of not considering the effective time of insect attractant, weakening effect of attractant in the later stage, and large amount of attractant, so as to improve the effective period of attractant, The effect of sticky insects is good and the effective time is long

Embodiment 1
[0023] A kind of preparation method of insect attractant is as follows:
[0024] Step 1: Mix and heat plant-derived pheromone (phenylacetonitrile), insect sex pheromone (methyl anthranilate), ethylene glycol, water, and soybean lecithin to 50°C to dissolve and disperse, and then stir and disperse to obtain primary emulsion; Wherein, plant source pheromone, insect sex pheromone are 3% of microemulsion gross weight; Solubilizer (ethylene glycol) is 10% of microemulsion gross weight, and lecithin is 3% of microemulsion gross weight; water;
[0025] Step 2: Use a high-pressure homogenizer (APV-1000 produced in Germany) to emulsify at high speed (emulsification pressure 300 bar, emulsification time 1 minute / time, emulsification times 3 times) to disperse it to obtain a microemulsion;
[0026] Step 3: Disperse 10g microemulsion in 90g sticky shellac, and stir to disperse. Sticky shellac is obtained by stirring and dispersing 20wt% SBR, 40wt% tackifying resin, 5wt% rosin and the res...
Embodiment 2
[0028] A kind of preparation method of insect attractant is as follows:
[0029] Step 1: Mix and heat the plant source pheromone (cis-3-hexenol), insect sex pheromone (o-methoxyphenol), ethylene glycol, water, and egg yolk lecithin to 44°C to dissolve and disperse, and stir to disperse Obtain primary emulsion; Wherein, plant source pheromone, insect sex pheromone are 4% of microemulsion gross weight; Cosolvent (ethylene glycol) is 5% of microemulsion gross weight, and lecithin is 4% of microemulsion gross weight ; the remainder of the water;
[0030] Step 2: Use a high-pressure homogenizer (APV-1000 produced in Germany) to emulsify at high speed (emulsification pressure 300 bar, emulsification time 1 minute / time, emulsification times 3 times) to disperse it to obtain a microemulsion;
[0031] Step 3: Disperse 8g microemulsion into 92g sticky shellac, stir to disperse, sticky shellac is obtained by stirring and dispersing the SBR of 30wt%, the tackifying resin of 30wt%, the ro...
Embodiment 3
[0033] A kind of preparation method of insect attractant is as follows:
[0034] Step 1: Mix and heat plant-derived pheromone (phenylacetonitrile), insect sex pheromone (butyl hydroxyanisole), ethylene glycol, water, and egg yolk lecithin to 47°C to dissolve and disperse, and then stir and disperse to obtain primary emulsion; , plant source pheromone, insect sex pheromone are 3.5% of microemulsion gross weight; Solubilizer (ethylene glycol) is 8% of microemulsion gross weight, lecithin is 4% of microemulsion gross weight; Surplus water ;
[0035] Step 2: Use a high-pressure homogenizer (APV-1000 produced in Germany) to emulsify at high speed (emulsification pressure 300 bar, emulsification time 1 minute / time, emulsification times 3 times) to disperse it to obtain a microemulsion;
[0036] Step 3: Disperse 8g microemulsion into 92g sticky shellac, stir to disperse, sticky shellac is obtained by stirring and dispersing the SBR of 30wt%, the tackifying resin of 30wt%, the rosin ...
