Abstract
The invention discloses a method for improving the printability of electronic paste. The electronic paste is used for printing a pattern and manufacturing a thick film element, and terpineol in the molecular formula of C10H18O is added into the electronic paste. The method disclosed by the invention has the advantages of simplicity in manufacturing, easiness in printing and good printing effect.
Description
Technical field
The present invention relates to a kind of improvement method that is used for the electrode slurry of solar cell manufacturing, particularly a kind of method that improves the electric slurry printability.
Background technology
At present, along with the further exhaustion of oil, coal traditional energy, the basis and the application study of photovoltaic generation more and more paid attention in countries in the world.How to improve the photoelectric transformation efficiency of battery sheet, assembly, to fields such as assembly auxiliary materials, the research worker has done a large amount of work from crystal silicon raw material, battery structure, battery process, cell size.Wherein the making of the electrode of solar battery sheet mainly is to adopt serigraphy and sintering process to form gate line electrode.In order to reduce the shading area of anodal grid line, the grid line width of battery is progressively to thin grid bearing development.Yet the viscosity of electric slurry itself and rheological characteristic have all determined its printing performance; Existing electric slurry is a kind of paste that is mixed through three-roll rolling by pressed powder and organic solvent; After dilution, be used for graphic printing; But when printing reached certain grid line width, it is bad that empty seal, broken string or the like printing will take place.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that improves the electric slurry printability, makes simply, is easy to printing, and printing effect is good.
The technical scheme that technical solution problem of the present invention adopts is: a kind of method that improves the electric slurry printability, said electric slurry are used for graphic printing, make thick film element, in said electric slurry, add a kind of terpinol, and its molecular formula is C
10H
18O.
Terpinol of the present invention is that three kinds of isomers of terpinol are first position terpinol, second position terpinol and third terpinol mixture with arbitrary proportion; Though these three kinds of isomers structures are variant but its physical property is basic identical, its each molecular structural formula is distinguished as follows:
Third terpinol of terpinol second position, first position terpinol
The terpinol that the present invention adopts can be raw material with turpentine oil, is emulsifying agent to add a small amount of peregal in the sulfuric acid, carries out hydration reaction at normal temperatures, make main component firpene in the turpentine oil generate terpini hydras after, through dewater thick terpinol, make through fractionation.Wherein the mixed proportion of first position terpinol, second position terpinol or third terpinol is indefinite.
The slurry that the present invention is at first relatively poor with printing performance or produce used doing in the bottle that it is suitable that old slurry is packed into adds a certain amount of terpinol with dropper, adds the terpinol of 2ml to about the 3ml in general every thousand grams of slurry; The bottle cap of screwing then, and use rubber belt sealing is put on the agitator rotating speed with 10-20 commentaries on classics/min again and is stirred to and mixes, and mixing time was generally 24 hours; Take out the slurry stir at last, remove sealant tape and bottle cap, re-use perching knife and manually be stirred to evenly and just can normally use.
Electric slurry among the present invention can be the slurry or the dried old slurry of poor-performing.The agitating device that the present invention uses is horizontal mixer; The dropper that uses is common glue head dropper.
The invention has the beneficial effects as follows: before electric slurry uses, add a kind of terpinol; Thixotropy, rheological characteristic and the viscosity performance of original electric slurry have been improved; Make it in screen printing process, cross China ink through half tone more easily and to stock, form clear N/R figure; Easy and simple to handle, be applicable to large-scale production, and practiced thrift production cost.
The specific embodiment
Embodiment 1: the positive electrode slurry of 2kg is added in the bottle, adopt dropper that the terpinol of 4ml is also added in the bottle, the bottle cap of screwing then, and use rubber belt sealing is put on the agitator rotating speed with 15 commentaries on classics/min again and is stirred to and mixes, and mixing time is 24 hours; Take out the slurry stir at last, remove sealant tape and bottle cap, re-use perching knife and manually be stirred to evenly and just can normally use, improved thixotropy, rheological characteristic and the viscosity performance of original electric slurry, make its printing performance obtain significantly improving.
Embodiment 2: the positive electrode slurry of 3kg is added in the bottle, adopt dropper that the terpinol of 8ml is also added in the bottle, the bottle cap of screwing then, and use rubber belt sealing is put on the agitator rotating speed with 20 commentaries on classics/min again and is stirred to and mixes, and mixing time is 24 hours; Take out the slurry stir at last, remove sealant tape and bottle cap, re-use perching knife and manually be stirred to evenly and just can normally use, improved thixotropy, rheological characteristic and the viscosity performance of original electric slurry, make its printing performance obtain significantly improving.
Claims (2)
1. method that improves the electric slurry printability, said electric slurry are used for graphic printing, make thick film element, it is characterized in that: in said electric slurry, add a kind of terpinol, its molecular formula is C
10H
18O.
2. a kind of method that improves the electric slurry printability as claimed in claim 1 is characterized in that: described terpinol is the mixture with arbitrary proportion of first position terpinol, second position terpinol and third terpinol.
