USE - The graphene dispersion is useful for front glass coating of automobiles. ADVANTAGE - The method realizes that the dispersion has good design adaptability and has highly intensive parts, saves a lot of mechanical operations, corrosion resistance in harsh environments, significant dielectric strength and resistance to leakage traces, low thermal conductivity, microwave penetration and good dent resistance, has precise dimensions, good stability and maintains good strength in a wide temperature range. DETAILED DESCRIPTION - Synthetic method for graphene dispersion, comprises mixing raw material as follows (1) manually preparing glass fiber, resin and graphene, and selecting high-quality glass fiber, resin and grapheme, (2) pouring the resin into soft water, adding sodium hydroxide, adjusting the pH to 9.5-10.5, adding initiator, closing the reactor and reacting for 1-2 hours, and (3) adding the emulsifier and stirring continuously for 15-20 minutes to obtain the resin paste, storing the resin paste, glass fiber and graphene in a cool place, production of sheet molding compound (SMC) material comprises (a) feeding the resin paste to the paste squeegee, and placing the shaving chute above the moving carrier film, and the paste squeegee controls the coating amount of the resin paste, (b) feeding the glass fiber and graphene into the rotary cutter located above the resin paste-coated carrier film, and cutting the glass fiber into the required length and dropped onto the resin paste, and (c) controlling the content of glass fiber and graphene by the moving speed of the carrier film, downstream of the cutting zone, attaching another carrier film coated with resin paste to the chopped glass fiber with the resin paste facing down, and passing through the kneading roller, saturating the glass fiber with the resin paste, and extruding the air inside the resin paste out of the sheet, compression molding as follows (i) placing the SMC sheet in place on the cutting table and cutting into a pre-designed size and shape, and the cutting table is usually set near the mold, (ii) stacking the cut material blocks and combining into a prescribed form, where the feeding method of each mold must be weighed to check whether the feeding amount is accurate, if necessary, corresponding adjustments must be made, adjusting the feeding method of each mold and combining as much as possible, and (iii) placing the pre-assembled sheet at the specified position on the surface of the hot mold for large or complex parts, placing the sheet in the mold step by step to ensure the accuracy of the spreading position, clamping and pressing as follows (I) setting the clamping and pressing mold of matched steel molds, coating or treating the surface to reduce wear, and heating the molds to 130-170 degrees C with oil or steam, and (II) laying the SMC material, closing the mold to apply pressure to the SMC material with the help of advanced pressure control technology, where the pressure can actually be changed during the molding process to achieve the best surface quality, and pressing the SMC material, and demolding cleaning as follows (A) closing the mold, curing the mold and opening the mold, and lifting the built-in ejector SMC material from the lower mold and releasing from the mold, care must be taken to avoid damage to the product during demolding, (B) removing the SMC material can be easily with a blade to remove the flash, and transferring to the holder to cool to room temperature, and (C) using soft water for wet cleaning, and a hair dryer to blow dry, manually observing whether there are cracks on the surface of the SMC material, measuring the thickness of the SMC material, and storing in a box if it is qualified.
