preparation example Construction

[0030] The preparation method of compound sticky shellac base-material comprises the steps:

[0031] (1) At 25~35℃, mix polyethylene glycol, dichloroethane and triethylamine according to the mass ratio of 1:6~10:13, stir magnetically at 350~600r / min for 30~55min, then move to Ice-water bath, add reagent A with 12-20 times the mass of polyethylene glycol to mix, shake at 250-300r / min for 25-50min, remove from the ice-water bath, let stand at room temperature for 20-24h, filter, take the filtrate according to the mass ratio of 7-12 : 5 Add ether at 2~5°C and mix, let it stand for 15~30min, filter with suction, take the filter residue and dry it in an oven at 60~80°C for 4~8h to obtain a dried product;

[0032] (2) According to the mass ratio of 3:1~2:15~25:5, take 2-vinyl-4,6-diamino-1,3,5-triazine, N,N-dimethylacrylamide, di Methyl sulfoxide and dry matter are mixed in a reaction kettle, magnetically stirred at 500~800r / min for 30~60min, and TiO with 8~15% dry matter is added ...

Embodiment 1

[0041] Reagent A: Mix acryloyl chloride, dichloromethane and water at a mass ratio of 1:3:15 to obtain Reagent A.

[0042] Reagent B: Mix NaOH solution with a mass fraction of 20% and sodium carbonate solution with a concentration of 0.1mol / L at a mass ratio of 1:10 to obtain Reagent B.

[0043] Self-made auxiliaries: at 35°C, take 60 parts of (N-amidino) dodecyl acrylamide, 30 parts of polyethylene glycol phosphate, and 4 parts of p-dichlorobenzene in CO 2 Mix under atmosphere, and stir with 400r / min magnetic force for 40min to obtain the self-made adjuvant.

[0044] Rubber material: mix peach gum, shellac and donkey-hide gelatin according to the mass ratio of 5:1:1 to get the rubber material.

[0045] Pretreatment of longicorn beetle feed: take longicorn longicorn adults and feed them with sawdust for 3 days. During the feeding process, spray them with hawthorn juice twice the weight of longicorn longicorn adults every 4 hours. After the cultivation is completed, pre-cultiv...

Embodiment 2

[0059] Reagent A: Mix acryloyl chloride, dichloromethane, and water in a mass ratio of 1:6:15 to obtain Reagent A.

[0060] Reagent B: Mix NaOH solution with a mass fraction of 20% and sodium carbonate solution with a concentration of 0.1mol / L at a mass ratio of 1:15 to obtain Reagent B.

[0061] Self-made auxiliaries: at 45°C, take 80 parts of (N-amidino) dodecyl acrylamide, 50 parts of polyethylene glycol phosphate, and 8 parts of p-dichlorobenzene in CO 2 Mix under atmosphere, and stir with magnetic force at 700r / min for 60min to obtain the self-made adjuvant.

[0062] Rubber material: Mix peach gum, shellac and donkey-hide gelatin according to the mass ratio of 5:3:1 to get the rubber material.

[0063] Pretreatment of longicorn beetle feed: take longicorn longicorn adults and feed them with sawdust for 5 days. During the feeding process, spray them with hawthorn juice that is 4 times the weight of longicorn longicorn adults every 7 hours. After the cultivation is complet...

Abstract

The invention relates to an insect sticking glue for tree trunks, and belongs to the technical field of diseases and insect pests prevention and treatment. A hydrogen-bond-reinforced tear-resistant shape memory hydrogel base material is synthesized with polyethylene glycol, N,N-dimethylacrylamide and other raw materials, the base material has good tensile properties, and the good tensile resistance effect can be realized without the need for external additives to realize driving; an added self-made auxiliary agent has an amphiphilic property, and vesicles can be formed in the system by self-assembly of the auxiliary agent, and an environment-friendly multi-related insect sticking glue system is formed through relations of environment-friendly insect sticking and insecticidal effects, photosynthesis of plants and the growth of the vesicles; and longicorn beetles are subjected to the pretreatment culture to stimulate the secretion of gastric juice and hormone-like compounds in vivo, themildew of the insect sticking glue is avoided by the cooperation with a porous structure of the colloid, and then the high tensile resistance and the environment-friendly performance can be maintainedfor a long time. The problems of poor tensile resistance and poor environment-friendly performance of commonly used insect sticking glues at present are solved.

Description

technical field [0001] The invention relates to sticky shellac for tree trunks, belonging to the technical field of disease and insect pest control. Background technique [0002] With the development of society and the enhancement of people's awareness of environmental protection, people gradually find that the use of chemical pesticides will have a destructive impact on the environment and ecosystem. The so-called pollution-free control method means that the control measures are safe and harmless to people, livestock, poultry, fish, bees and beneficial insects (that is, the natural enemies of pests), and at the same time have no damage to the ecological balance, and the agricultural products meet the requirements of pollution-free agriculture. Therefore, the control of pests that affect agricultural and forestry production is now shifting from purely chemical methods to pollution-free control methods. Therefore, the use of pollution-free control methods is particularly imp...
