Problems solved by technology

Many domestic units are using EPG to carry out related research. The demand for conductive silver glue is relatively large, but at present, conductive silver glue needs to be imported from abroad, which has caused great obstacles to my country's scientific research: first, the order cycle is long, It takes about one month or even longer from ordering to receiving the goods; second, the cost is relatively high, and the cost of importing a tube (5ml) from abroad is at least 40 euros; third, the procedures are cumbersome. The control is very strict, and the purchase of silver glue from abroad requires the approval of the People's Bank of China and other departments

Embodiment Construction

[0010] The present invention illustrates the operation and effect of silver glue of the present invention through 4 examples. All raw material ratios are calculated by mass percentage in these examples.

[0011] ⑴ Preparation of silver colloid

[0012] The mass sum of silver powder, water-based paper glue, water and Triton X-100 and the mass percentage of each component in each embodiment are shown in Table 1. For each embodiment, each component is weighed with an electronic balance and placed in a 50 ml beaker, shaken and mixed evenly on a shaker, then the mixture is distributed in 5 ml centrifuge tubes, sealed centrifuge tubes with parafilm film, put Store in refrigerator at 4°C. Silver powder purity is 99.9% in this embodiment example, and particle size is 200 orders, and water-based liquid paper glue is a kind of water-based liquid paper glue that can mix evenly with silver powder, ethylene glycol octyl phenyl ether (Triton X- 100) is an antioxidant that can be evenly m...

Abstract

The invention discloses conductive elargol for use in pest electrical penetration graph technology, which is prepared by scientifically mixing 34.74 to 44.36 mass percent of silver powder, 31.20 to 43.43 mass percent of water-based liquid paper adhesive, 18.48 to 31.20 mass percent of pure water and 0.10 to 0.20 mass percent of tritonX-100. Compared with overseas products of the same kind, the conductive elargol for use in the pest electrical penetration graph technology has the advantages of definite formulation, low cost, simple and convenient manufacturing flow, quick preparation, simple use, and easy storage, and is very convenient for electropalatography (EPG) researchers in China to use widely. Experiments prove that the conductive elargol has higher conductivity than overseas products of the same kind, makes electropalatographic waveform more complete and is more simple and convenient for experimental application and use.

Description

technical field [0001] The invention relates to an insect piercing potential technology, in particular to a conductive silver glue for the insect piercing potential technology. Background technique [0002] The electrical penetration graph (EPG) is an important experimental technique in chemical ecology research. It is used to study the feeding behavior, poison transmission mechanism and plant resistance mechanism of piercing-sucking insects on host plants. etc. play an important role. Many domestic units are using EPG to carry out related research. The demand for conductive silver glue is relatively large, but at present, conductive silver glue needs to be imported from abroad, which has caused great obstacles to my country's scientific research: first, the order cycle is long, It takes about one month or even longer from ordering to receiving the goods; second, the cost is relatively high, and the cost of importing a tube (5ml) from abroad is at least 40 euros; third, the ...
