Problems solved by technology

Most of the existing insecticides on the market are water or powder, and the insecticidal effect is achieved through chemical components. The spraying of pesticides in high temperature weather can easily cause human poisoning
The conventional utilization rate of chemical pesticides is only 50% to 60%, and there will be a large amount of pesticide residues in plants, which not only causes waste of resources, but also causes serious environmental pollution

preparation example Construction

[0029] The preparation process of the humic acid-type insect-proof pheromone water-absorbent resin:

[0030] 1) Weigh the weathered coal sample after drying with 80 mesh, according to the solid-liquid ratio of 1:10 (g·mL -1 ), add dilute hydrochloric acid to heat and boil for activation, after cooling, wash the precipitate to neutrality, then add 10% potassium hydroxide solution at a solid-to-liquid ratio of 1:8, heat and stir in a boiling water bath at 100 ° C for 1 hour, then cool To room temperature, centrifugally filter, weigh the quality of the filter residue after filtration; add dilute hydrochloric acid to the filtrate to adjust the pH to 1, let stand for 24 hours, filter, collect the precipitate and dry to constant weight to obtain potassium humate.

[0031] 2) 0.4 parts of nano-SiO 2 Ultrasonic dispersion in acetic acid solution to obtain 2% SiO 2 To the dispersion liquid, 6 parts of carboxymethyl cellulose prepared in advance was added under stirring, and the solut...

Abstract

The invention provides a humic acid-type insect-controlling pheromone water-absorbent resin and a preparation method thereof. In parts by mass, the preparation raw materials include: 8-10 parts of humate, 6-8 parts of cellulose, and 10-12 parts of hydrophilic Monomer, 2-4 parts of terpenoid insect-proof pheromone, 0.5-0.7 part of initiator and 0.1-0.2 part of cross-linking agent. Dissolve cellulose and humate in water, mix thoroughly, add hydrophilic monomer, initiator, cross-linking agent and terpenoid insect-proof pheromone under heating and stirring at 40-50°C, and heat up to 60-75°C for cross-linking The reaction is carried out for 2 to 3 hours to obtain a humic acid-type insect-proof pheromone water-absorbent resin. The method is simple to operate and environmentally friendly; the superabsorbent resin prepared by the method can not only make plants have the functions of resistance to diseases and insect pests, antibacterial, cold resistance, etc., but also effectively alleviate the pollution of the environment and the harm to animals and plants caused by the use of chemical pesticides.

Description

technical field [0001] The invention belongs to the application field of agricultural chemical fertilizers, and particularly relates to a humic acid-type insect-proof pheromone water-absorbent resin and a preparation method thereof. Background technique [0002] At present, the commonly used pesticides on the market are chemical pesticides, which can target most diseases and insect pests, but there are certain problems. Most of the existing pesticides on the market are water or powder, and the insecticidal effect is achieved through chemical components. The spraying of pesticides in high temperature weather can easily cause human poisoning. The conventional utilization rate of chemical pesticides is only 50% to 60%, and there will be a large amount of pesticide residues in plants, which not only causes waste of resources, but also causes serious environmental pollution. SUMMARY OF THE INVENTION [0003] In order to overcome the existing defects of chemical insecticides, t...
