Description
Technical field
The present invention relates to the electronic-grade glass fiber cloth of a kind of electronic-grade glass fiber cloth flaky process technique and production thereof.
Background technology
Electronic-grade glass base cloth is the upstream substrate of supply PCB industry, flourish along with electron trade in recent years, compact, lamination, the high frequency of electronic product, multifunctional integrated sustainable development, also more and more harsher to the performance requirement of upstream electronic material substrate, about the wettability of fiberglass-based cloth, DIMENSIONAL STABILITY, heat-resisting quantity (interlaminar strength), surperficial low roughness will be the emphasis that downstream client gives more sustained attention and requires.
The novel lead-free resin that present down-stream enterprise uses in a large number, environment friendly non-halogen resin and high Tg resin, mainly through the polyfunctional epoxy resin of chemical modification, also can add the filler of vast scale in addition, the adjustment change of downstream high performance resin, make the electron glass fiber cloth base material of traditional existing manufacture technics be not suitable with it, not mate, cause the problems such as wettability declines, prepreg internal gas is not easily discharged, the inner easily generation of substrate is empty.
Whole slurry is maintained mostly for the process of fiberglass-based cloth in current domestic industry and through, weave, destarch, coupling agent treatment traditional handicraft level on, fibrillation degree and wettability limited, cannot mate and meet the requirement of high performance resin.
Summary of the invention
The object of the invention is the deficiency overcoming traditional handicraft, the electronic-grade glass fiber cloth of a kind of electronic-grade glass fiber cloth flaky process technique and production thereof is provided, improving and excavating existing glass cloth production technology, more thoroughly fibrillation degree and flatness is obtained by stifling swelling process, electronic-grade glass fiber cloth has that wettability is good, impregnation is high, permeability is little, the entirety of smooth surface, glass cloth is flat thus, and improve the adhesion with resin boundary surface, strengthen the adaptability with downstream high performance resin.
The present invention is achieved by the following technical solutions, and in turn include the following steps enforcement:
First, by while reel for yarn is in warp beam to yarn monofilament starching, high bloating tendency starch selected by slurry, the temperature of monofilament starching controls at 30 ~ 70 DEG C, baking temperature 120 DEG C ~ 180 DEG C, running speed 50 ~ 150m/min, carry out whole slurry processing process, by obtain through beam warp and through, employing air-jet loom weaving after obtain non-degreasing glass fabric.
Then, above-mentioned non-degreasing glass fabric is positioned in steam steam stove and carries out stifling swelling process, be specially: in the cavity of a sealing, non-degreasing cloth is placed wherein, chamber vacuum degree 0.01 ~ 0.3 ~ MPa, duration 0.5h ~ 24h, saturated vapour pressure 0.1 ~ 1.2Mpa, non-degreasing cloth under hot and humid environment through the injection of saturated vapor gas, fumigation action, make the starch heat that the height of yarn interior is bloating tendency, meeting wets swells rapidly, yarn bundle certain hour will make the gap of silvalin interfascicular widen under resting on hot and humid environment, formation secondary structure is recombinated.
Subsequently, by the glass cloth after above-mentioned swelling process, at high temperature carry out laser heating and smoldering ungrease treatment, after ungrease treatment, obtain the glass fabric that content of organics controls within 0.01% ~ 0.1%.
Finally, the glass cloth through ungrease treatment is carried out fibrillation process through high-pressure spray, get rid of unnecessary moisture content through extruding, and obtain the glass fabric that fibrillation is even, thickness declines, loosely organized, flattening degree is high after surface treating machine dipping silane coupler.
The present invention improves the novelty of existing technique, increases stifling swelling technique, promotes the fibrillation effect of glass cloth, improve the collapsibility of glass cloth thus, reduce glass cloth surface roughness, improve the adhesion at resin and glass cloth interface, to adapt to the change requirement of the new environment in downstream.Glass fabric after present invention process process, loose in silvalin bundle, longitude and latitude intertwined point is level and smooth, and warp width increases, and glass cloth thickness declines, and internal stress reduces.
