Abstract
The invention discloses a manufacturing method for high-strength electronic grade glass fiber cloth. The manufacturing method for the high-strength electronic grade glass fiber cloth includes the steps of 1, softening; 2, splitting; 3, fusing of carbon fibers; 4, shaping. The softening step includes the sub-steps that electronic grade glass fiber cloth is placed in an ultrasonic cleaning machine for ultrasonic cleaning for 30-40 min, the clean water temperature in the ultrasonic cleaning machine is set to be 40-50 DEG C, and during the cleaning, paraffin oil is added as a cleaning agent to soften the surface of the electronic grade glass fiber cloth. The manufacturing method for the high-strength electronic grade glass fiber cloth has the advantages that through the softening and the splitting, surface fibers of the electronic grade glass fiber cloth are not damaged, the fibers are dispersed at the same time, the loosing occurs, the carbon fibers are fused among the fibers to form a composite, the whole strength of the electronic grade glass fiber cloth is strengthened, the final shaping provides proper temperature and pressure to make the carbon fibers closely be combined with the surface fibers of the glass fiber cloth, and the surface of the electronic grade glass fiber cloth is smooth, and no fuzzing is generated.
Description
Technical field
The present invention relates to the manufacture method of electronic-grade glass fiber cloth.
Background technology
Electronic grade glass cloth (e-glass cloth) is the main reinforcing material of hardboard, by 200 ~ 400 E-glass silks
Twisted becomes organdy (yarn) to be woven into cloth with flat weaving method again, finally does cure process with silicon methane again.Because the difference of thickness
Glass-fiber-fabric can be divided into Multiple Type, most-often used for 7628 (0.18mm is thick), 2116 (0.09mm is thick), 1080 (0.056mm
Thick) etc. 3 types.
Glass-fiber-fabric system printed circuit board (PCB) (pcb) main material, 7628 are mainly used in general information product, in current pcb
In the case that application is still based on information products application, 7628 glass-fiber-fabrics are still the main flow on market, and ratio accounts between 70 ~ 75%；
For thin plate 2116 and 1080 glass-fiber-fabrics account for 25 ~ 30%, are applied to the high-tech products such as notebook computer, mobile phone, military affairs more.
The weaving process of glass-fiber-fabric includes warping (warping), sizing (sizing), heald frame (draw-in), weaves cotton cloth
(weaving), burn clean (heating cleaning), silicon alkane processes (silane finishing) etc., each station will be carried out
Chemical examination and QC, just can ensure that the quality of product.It is relatively low, non-refractory scarce to there is intensity in existing electronic-grade glass fiber cloth
Fall into.
Content of the invention
The technical problem to be solved in the present invention is existing electronic-grade glass fiber cloth low intensity, non-refractory, carries for this
For a kind of manufacture method of high intensity electronic-grade glass fiber cloth.
The technical scheme is that the manufacture method of high intensity electronic-grade glass fiber cloth, it comprises the following steps:
(1), soften: electronic-grade glass fiber cloth is placed on ultrasonic cleaning 30-40min, ultrasonic washing unit in ultrasonic washing unit
In clear water temperature be set as 40-50 DEG C, period add paraffin oil make electronic-grade glass fiber cloth surface soft as abluent
Change；(2), fibrillation: the electronic-grade glass fiber cloth through sofening treatment is taken out in the environment of being placed on 2-4mpa, 40-50 DEG C
Dry, place into ultrasonic cleaning 20-30min in ultrasonic washing unit, period adds the steel ball 200-300 that particle diameter is 5-10mm
Individual, make between the fiber of electronic-grade glass fiber cloth occur pine from；(3), the fusion of carbon fiber: add in ultrasonic washing unit
Appropriate carbon fiber, the clear water temperature in ultrasonic washing unit is set as 50-55 DEG C so that carbon fiber incorporates E-glass
Form high intensity electronic-grade glass fiber cloth in fiber cloth；(4), moulding: to take out high intensity electronic-grade glass fiber cloth, electricity consumption is pressed
Flatiron makes its surfacing for 10-20 time to bucket repeatedly, and the baseplate temp of electric iron is 45-50 DEG C.
The invention has the beneficial effects as follows through softening, fibrillation makes electronic-grade glass fiber cloth not destroy the same of surface fiber
When break up fiber and be allowed to pine occurs be fused to formation complex between fiber from, carbon fiber, strengthen electronic-grade glass fiber cloth
Bulk strength, last moulding provide suitable temperature and pressure and so that carbon fiber and the surface fiber of glass fabric is closely tied
Merging makes the surfacing of electronic-grade glass fiber cloth phozy.
