Description
Technical field
The present invention relates to patch capacitor technical field, more particularly to a kind of cleaning agent for patch capacitor.
Background technology
Patch capacitor is the important electronic component in electronic product surface mounting technique, with the resistance with certain resistivity
Slurry is printed onto on ceramic substrate again sintered form.
Chip capacitor has used the porcelain containing adhesive in manufacture craft, consisting of macromolecule resin, curing agent,
Sintering temperature is more than 1000 DEG C in plasticizer, dispersant, defoamer and porcelain, making, and porcelain forms firm ceramic diaphragm,
Some residues can also be produced simultaneously, it is necessary to which residue thoroughly cleaning totally just can guarantee that to the temperature stability of patch capacitor,
Capacity stability and dielectric loss stability.It is trichloro ethylene, dichloromethane etc. to have used cleaning agent main component for many years.But
Greatly, dichloromethane volatilization is too fast, in order to ensure cleaning quality, it is necessary to constantly add cleaning agent, makes for the toxicity of trichloro ethylene
Rise into production cost, in order to overcome the drawbacks described above of cleaning agent there is provided a kind of cleaning force strong, the low environment-friendly cleaning agent of volatility
It is very necessary.
The content of the invention
For above-mentioned the deficiencies in the prior art, the present invention provides a kind of cleaning agent for patch capacitor, solves existing patch
Chip capacitor cleaning agent high volatility, not environmentally the problem of.
The technical proposal of the invention is realized in this way：A kind of cleaning agent for patch capacitor, by weight percentage by
Following components is constituted：Ethanol 40~60%, ethyl glutarate 20~30%, butyl 10~20%, isobutyl acetate 5
~15%, surfactant 3~8%, dispersant 2~5%.
A kind of cleaning agent for patch capacitor, it is composed of the following components by weight percentage：Ethanol 45~52%, penta 2

~4%.Wherein it is preferred to, the surfactant is neopelex.
Wherein it is preferred to, the dispersant is triethanolamine.
Beneficial effects of the present invention：
1. the cleaning agent of the present invention employs alcohol, ester, ethers combination solvent, washing dynamics is substantially increased, washing power reaches
To more than 99%.
2. surfactant is added in the cleaning agent of the present invention, wherein, the neopelex of addition is senior
Surfactant, adds the wetability and permeability of cleaning agent, reduces the interfacial tension between cleaning agent and selected object,
The stripping of residue is contributed to come off.
3. the cleaning agent of the present invention adds dispersant, dispersant can will peel off cast and be scattered in cleaning fluid, Bu Huizai
Deposition, it is ensured that the cleanliness factor of cleaned object.
