Abstract
This invention relates to method and equipment for infiltrating reinforced material and liquid resin. The equipment covers a container onto the connected infiltration adhesive tanks, and forms an isolated zone by liquid sealing, thus can realized negative pressure pre-infiltration.
Description
Technical field:
The present invention relates to a kind of production preimpregnation field method and equipment technical field thereof that is applied in the copper-clad plate field with prepreg, refer in particular to a kind of strongthener and good method and the device thereof that soaks into of liquid resin.
Background technology:
Copper-clad plate field prepreg (bonding sheet), just with the work in-process strongthener, as: materials such as the flaky material of paper or fabric and glass fibre soak with liquid resin, liquid resin adds that as: Resins, epoxy etc. solvent or solidifying agent make by thermosetting resin usually, and heat drying flooded the strongthener of resin and obtained then.Because strongthener is the preimpregnation gum box and the main impregnation tank of the last glue machine of process rapidly, liquid resin can't fully soak into strongthener at short notice, and the residual a large amount of small gases of meeting in the strongthener, form the correlated quality hidden danger when producing multilayer circuit board in follow-up copper-clad plate pressing plate or the electron trade easily, as situations such as microbubble, weave texture occur.
Summary of the invention:
Purpose of the present invention just is by improving existing technology, solve strongthener such as glasscloth, insulation paper, fabric etc. and soak into inadequate problem, provide a kind of glasscloth and good method and the device thereof that soaks into of liquid resin with liquid resin.
For achieving the above object, the present invention adopts following technical scheme: a kind of with strongthener and the good method of soaking into of liquid resin, container of back-off on the impregnation tank, make the container of back-off and glue liquid level form a sealing area with atmospheric isolation, and then in this regional mode that adopts extracting air, make and form a negative pressure chamber between this zone and the external atmosphere pressure, when this zone of strongthener process, owing to have pressure reduction inside and outside scribbling liquid resinous strongthener, small gas in the strongthener is forced to rapid extraction, liquid resin soaks into strongthener rapidly under the effect of negative pressure, thereby has realized the negative pressure preimpregnation.
A kind of with strongthener and the good device that soaks into of liquid resin, it is by back-off groove of back-off on an interconnected pair of impregnation tank, forms a both arms fluid column that is W shape; Upper and lower ends at the right and left of interconnected pair of impregnation tank is respectively arranged with strongthener operation deflector roll; Be provided with a notch in the upper end of back-off groove, on described notch, vacuum pump be installed; Form a negative pressure chamber that completely cuts off with ambient atmosphere between the glue liquid level in the back-off groove and the interconnected pair of impregnation tank, negative pressure chamber both sides be provided with the extrusion roll that is used in twos, then be provided with floating roll in the centre.
The invention has the beneficial effects as follows: adopted the pre-bath unit of this negative pressure to carry out the negative pressure preimpregnation, realized that strongthener and liquid resin well soak into, after the negative pressure preimpregnation its progressive be embodied in following some:
1, transmittance can obviously increase after the sufficient strongthener of impregnation water was scraped glue.
2, the sufficient bonding sheet of impregnation water can be implemented under the relative viscosity higher condition, and the sheet material that produces is not prone to the shortcoming that weavy grain appears.
3, because of little, the no weavy grain of bonding sheet gummosis water appears, the base material that will help to improve copper-clad plate pressing plate and multi-layer circuit board platen is time apparent.
Description of drawings:
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is a negative pressure preimpregnation apparatus structure synoptic diagram of the present invention.
Embodiment:
The present invention adopts following technical scheme: a kind of with strongthener and the good method of soaking into of liquid resin, container of back-off on impregnation tank 1, make the container of back-off and glue liquid level form a sealing area with atmospheric isolation, and then in this regional mode that adopts extracting air, make and form a negative pressure chamber between this zone and the external atmosphere pressure, when this zone of strongthener process, owing to have pressure reduction inside and outside scribbling liquid resinous strongthener, small gas in the strongthener is forced to rapid extraction, liquid resin is under the effect of negative pressure, soak into strongthener rapidly, thereby realized the negative pressure preimpregnation.
A kind of with strongthener and the good device that soaks into of liquid resin, it is by back-off groove 2 of back-off on an interconnected pair of impregnation tank 1, forms a both arms fluid column that is W shape; Upper and lower ends at the right and left of interconnected pair of impregnation tank 1 is respectively arranged with strongthener operation deflector roll 3; Be provided with a notch 4 in the upper end of back-off groove 2, on described notch 4, vacuum pump 5 be installed; Form a negative pressure chamber that completely cuts off with ambient atmosphere between the glue liquid level in the back-off groove 2 and the interconnected pair of impregnation tank 1, negative pressure chamber both sides be provided with the extrusion roll 6 that is used in twos, then be provided with floating roll 7 in the centre.
The present invention is by container of back-off above two impregnation tanks 1 of interconnection, and the form of employing fluid-tight, forms a zone isolated with ambient atmosphere, and then adopts the mode of extracting air in this zone, realizes the negative pressure preimpregnation.The container of back-off+glue liquid level forms the sealing area isolated with ambient atmosphere, adopts vacuum pump 5 extracting airs in this zone then, forms a negative pressure chamber; Two impregnation tank 1+ back-off grooves 2 of interconnection, the fluid column of both arms of formation reduces the liquid resin consumption to greatest extent when having realized fully providing liquid-column height (pressure reduction) thus.
Strongthener zone in negative pressure region, owing to have pressure reduction inside and outside scribbling liquid resinous strongthener, be forced to rapid extraction under the suction function of small gas in negative pressure region in the strongthener, under the suction function of liquid resin in negative pressure region, soak into strongthener rapidly simultaneously.Vacuum magnitude can be regulated and control as required, and liquid-column height both provided pressure reduction, and as the feedback system of regulating vacuum tightness.
At negative pressure region, adopt extrusion roll to scrape off unnecessary presoak, adopt floating roll 7 adjustment of tonicity in the middle and control strongthener robust motion in process of production.
Adopt the pre-soaking system and test of double flute negative pressure, promptly can reduce liquid resinous consumption, can satisfy the two-part preimpregnation again, and adopt the specific demand of different liquid resin preimpregnation glue.So this device can be applicable to all preimpregnation materials; Comprise glass cloth, insulation paper, fabric etc.
Certainly, the embodiment of the above is a preferred embodiments of the present invention, is not to limit the scope of the present invention, so all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify, and all should be included in the present patent application claim.
