Problems solved by technology

Traditionally, most of this kind of PCB circuit board adopts imported PI flexible copper clad laminates. The price of this kind of copper clad laminates is relatively high. Since the PI film is not filled with reinforcing materials, its strength is also limited to the strength of PI itself.

[0031] Examples 1 to 5: one kind of high strength and high flexibility of the aramid cloth CCL

[0032] One kind of high strength and high flexibility of the aramid fabric laminates of the present invention may be implemented by the following steps:

[0033] Step one, the desired material epoxy resin, curing agent, accelerator, and a solvent at a mass shown in Table 1 were uniformly mixed into the glue mix;

[0034] Step two, shown in Table 1, the aramid fiber cloth pretreated solvent soak, bake temperature 180 [deg.] C, to remove surface impurities aramid fiber, aramid fiber cloth impregnated then a silane coupling agent solution and 100 ℃ drying, improved aramid fiber binding capacity of the resin; the KH570 silane coupling agent;

[0035] Step three, the process good of aramid fiber cloth impregnated with a step of mixing glue, 3-10min heating oven 140 ~ 200 ℃, cooled to obtain a flow of 3% to 15% of a prepreg;

[0036] Step four, the prepreg and the copper foil laminated, a la...

Abstract

The invention provides a method for preparing a high-strength and high-flexibility copper-clad laminate of aramid cloth. ~150 parts of epoxy resin and 20~50 parts of solvent are uniformly mixed into a mixed solution; step 2, soak the aramid fiber cloth in alcohol solvent, bake at a high temperature of 180‑250 ℃, and then impregnate the aramid fiber cloth with silane coupling agent treatment solution and dried at high temperature to obtain the treated aramid fiber cloth; step 3, soak the treated aramid fiber cloth with the mixed glue in step 1, and dry to obtain a prepreg; laminate the prepreg with copper foil, and heat High-pressure molding to obtain high-strength and high-flexibility copper-clad laminates made of aramid fiber cloth.

Description

Technical field [0001] The present invention relates to the field of medical materials, one of high strength and flexibility Kevlar cloth CCL. Background technique [0002] Diversified development and popularization of medical products, medical materials industry made more demands. Currently some medical devices need to be equipped wearable detecting portion or the detection of such wearable device directly detecting apparatus as a whole. Such a wearable device, the inside of the PCB circuit boards must have high strength and high flexibility, to avoid breaking the patient physical activity. Such a circuit board PCB, in the conventional PI FCCLs mostly imported, such CCL price is relatively high, since no PI membrane reinforcing filler, which is also limited by the strength of the strength of PI itself. Inventive content [0003] Object of the present invention is to provide a high strength and high flexibility of the aramid cloth CCL preparation, CCL obtained by this method is ...
