Abstract
The invention discloses an adhesive used for pasting a laminated ceramic capacitor dielectric thin film as well as a preparation method and an application thereof. The adhesive is prepared by the following steps of: throwing 25-35% of resin, 42-55% of solvent, 10-20% of plasticizer, 1-3% of dispersant, 1.5-5% of defoaming agent and 2-5% of lubricating agent into a high pressure reactor, heating to the temperature of 120-150 DEG C and reacting for 10-12 hours while pressure of the reactor is 2-5MPa. The laminated ceramic capacitor dielectric thin film pasted by adopting the adhesive disclosed by the invention is ultrathin (thickness is 1-3mu m), thus volume of an electronic component can be greatly reduced, performance is greatly improved, and requirements of a flat computer and a smart phone can be met; and the obtained ceramic capacitor dielectric thin film has uniform contract, zero defect and no crack, and great help is provided for improving yield and consistency of the electronic component.

Background technology
Along with the development of infotech, people require increasingly highly to electronic product, require it to have high-performance and microminiaturization, thereby require electronic material also will constantly develop aspect high-performance, nanometer, the plyability.
China's lamination electronic devices and components (be mainly and mount multi-layer ceramic capacitor MLCC) are to grow up the nineties, and starting is late.Domestic company and the institute that is engaged in its auxilliary material research is few, but it requires height, and the cooperation that must obtain MLCC manufacturer could be developed, and MLCC company does not generally give mechanism of domestic institute too many support, thus domestic study in this respect fewer.Wherein the stack adhesive of MLCC use is generally imported materials and items.Certainly, more domestic companies with good conditionsi also are engaged in the research of this respect, strive for production domesticization; Such as FENGHUA ADVANCED TECHNOLOGY's patent No. 200910193676.6 " a kind of aqueous binder ", Ecological Environment Research Center, Chinese Academy of Sciences's patent No. 98124401.7 " ceramic adhesive ", Shanghai No.6 Radio Factory's patent No. 86108230 " electronic ceramic binder for film formation by flow and expansion "; Shanghai Silicate Inst., Chinese Academy of Sciences's patent No. is 201010135304.0 " a kind of ZnO voltage-sensitive ceramic is used inorganic adhesive ", and these inventions all can not be satisfied the production demand of MLCC, like the patent of FENGHUA ADVANCED TECHNOLOGY; It is a water-based; Though relatively environmental protection, drying time is long, the curtain coating thicker; Like the invention of Shanghai wireless six factories, the thickness of its curtain coating and uniformity coefficient all can not satisfy its needs.
Summary of the invention
For the shortcoming and deficiency that overcome prior art, primary and foremost purpose of the present invention is to provide a kind of tackiness agent, the ceramic dielectric film thickness ultra-thin (1-3um) of using this tackiness agent to make, thus the electronic devices and components volume is dwindled greatly; With its pottery dielectric film that makes shrink evenly, zero-fault, flawless, good article rate and the consistence that improves electronic devices and components had great help.
Another object of the present invention is to provide the preparation method of above-mentioned tackiness agent.
A purpose more of the present invention is to provide the purposes of above-mentioned tackiness agent.
The object of the invention is realized through following technical proposals:
A kind of as mounting the tackiness agent of multi-layer ceramic capacitor dielectric film, prepare by the composition of following mass percent:
