Embodiment 1

[0034] Embodiment 1, its steps are as follows:

[0035] (1) First add 100g tung oil with an acid value of 5mg / g into the reactor, and then add 15ml of sodium hydroxide with a mass percentage of 30% for reaction. The reaction temperature is 80°C and the stirring speed is 50r / min for 0.5h. Ready to use after the reaction is complete;

[0036] (2) According to the ratio of tung oil: emulsifier (mixed emulsifier of sorbitol lipid, phospholipid and lauric monoglyceride, mass ratio 1:1:1) mass ratio of 1:0.5, add the emulsifier to the above step 1) Among the reaction products, the emulsification treatment was carried out at a temperature of 90°C and a stirring speed of 50r / min for 0.5h, and the mixed solution after the treatment was ready for use;

[0037] (3) Finally, 0.2% of UV protective agent (nano-zinc oxide), 1% of thickener (sodium carboxymethyl cellulose), 0.2% of dispersant (sodium lauryl sulfate and polyoxyethylene polyoxypropylene block Copolymer (mass ratio 1:1) and fu...

Embodiment 2

[0039] Embodiment 2, its steps are as follows:

[0040] (1) First add 100g tung oil with an acid value of 2mg / g into the reactor, then add 10ml of calcium hydroxide with a mass percentage of 50% to react, and treat it for 2 hours at a reaction temperature of 60°C and a stirring speed of 100r / min. After the reaction is complete stand-by;

[0041] (2) According to the ratio of tung oil: emulsifier (fatty acid monoglyceride and sucrose ester, mass ratio 3:8), add the emulsifier to the reaction product of the above step 1) at a mass ratio of 1:1, stir at a temperature of 75°C Emulsification treatment at a speed of 80r / min for 2 hours, and the mixed solution after treatment is ready for use;

[0042] (3) Finally, add 0.5% UV protective agent (nano-titanium dioxide and phospholipid, mass ratio 0.2:1), 0.4% thickener (xanthan gum, polyethylene glycol, gum arabic and sodium alginate, mass ratio 1 : 1:0.5:1), dispersant 0.3% (sodium lauryl sulfate) and fungicide 0.05% (benzoic acid) ...

Embodiment 3

[0044] Embodiment 3, its steps are as follows:

[0045](1) First add 100g of oleic acid into the reactor, then add 10ml of calcium hydroxide with a mass percentage of 50% and 20ml of 20% ammonia water to react. The reaction temperature is 60°C and the stirring speed is 60r / min. use;

[0046] (2) Add the emulsifier to the reaction product of the above step 1) according to the mass ratio of oleic acid: emulsifier (sucrose ester) at a ratio of 1: 1, and emulsify for 2 hours at a temperature of 80°C and a stirring speed of 50r / min. The mixed solution after processing is ready for use;

[0047] (3) Finally, add 0.1% UV protectant (nano-titanium dioxide), 0.2% thickener (polyethylene glycol), 0.3% dispersant (sodium lignosulfonate) and 0.05% fungicide (benzoic acid) to the Step 2) In the obtained mixed solution, a kind of tung oil insecticide can be obtained after uniform mixing.

Abstract

The invention provides a method and process for preparing tung oil pesticide. The method comprises the following steps: refining tung oil with alkali, mixing with an emulsifier and uniformly mixing with other auxiliaries. The tung oil has effects of killing pests and inhibiting bacteria. The tung oil pesticide is simple in preparation, has a good pest killing effect and wide market application prospect, has the characteristics of fast action and long action, and can be used for reducing the usage of chemical pesticide and preventing pests from generating drug resistance. The tung oil pesticide does not have pollution in production and processing processes, has stable product quality, wide insecticidal spectrum, strong activity and convenience in use, and can be used for preventing and controlling beauveria bassiana, argyroneta aquatica, cabbage caterpillar, helicoverpa armigera, aphid, green leafhopper, cockroaches, acarid and the like.

Description

technical field [0001] The invention relates to the fields of agricultural planting and plant chemical industry, in particular to a preparation method of tung oil insecticide. Background technique [0002] Tung tung, a deciduous tree belonging to the family Euphorbiaceae, is native to China and is a special product resource in our country. The oil squeezed or extracted from tung oil seeds is called tung oil, which is the highest quality dry oil in the world. Tung oil is an excellent renewable resource with good ecological and economic value. Tung tung is an important industrial oil tree species. It has strong adaptability, easy growth, easy management, fast growth and quick production. [0003] Aloe tung has a long history of cultivation in my country. As far back as the "Supplements to Materia Medica" written by Chen Zangqi in the Tang Dynasty, there are "poppy tung trees grow in the mountains, trees like phoenix trees" and other historical records about the cultivation an...
