NOVELTY - Preparing compact graphene condom comprises preparing dense graphene by chemical vapor deposition in a silica cylindrical round mold with built-in spiral carbon fiber heat source and pure copper layer sprayed on the surface film and the graphene inner membrane by way of atomization catalyzed slow cooling graphene intimately bonded five hydroxy polyoxypropylene ether re-polymerization of polyether polyurethane, closing, drying, crimping, swelling, drying, testing and vacuum packing process to obtain final product. USE - The method is useful for preparing compact graphene condom (claimed). ADVANTAGE - The condom: has high intensity, high density, abrasion resistance, corrosion resistance, impact resistance and long service life. DETAILED DESCRIPTION - Preparing compact graphene condom comprises (i) (a) preparing silicon columnar round-head mold of built-in with spiral carbon fiber heat source in sealed space, (b) the silicon dioxide cylindrical internal surface spraying thickness of 5-8 mu m of pure copper layer, (c) sealing space at a rate of 150-180 standard cubic centimeter per minute into reducing atmosphere, (d) atmosphere continuously filling 5 minutes after the mold through heating for 30-35 minutes, then raising the temperature to 1020-1050 degrees C, (e) adjusting the reducing atmosphere feeding rate to 15-20 standard cubic centimeter per minute, 80-100 standard cubic centimeter per minute pass rate of methane, and (f) during 35-40 minutes, (ii) (a) taking outer layer obtained in (i) (using 3-5 bar gas pressure of the nitrogen, graphene film obtained in (f) and mold cooling to 300-350 degrees C, (b) disposing the mixed solution of propylene oxide, ethylene oxide, pentaerythritol and potassium hydroxide, and then pass into confined space after atomization, (c) loading negative electrostatic field in a confined space to keep the concentration of the fog unchanged by spraying continuously until the part cooling to room temperature to obtain graphene inner surface of the composite with graphene intimately bonded five hydroxy polyoxypropylene ether, and (d) immersing in a liquid environment containing diisocyanate polymerization to obtain polyurethane outer layer, and (iii) (a) taking out mold and introducing in 50-58 degrees C oven to drying, (b) surface of the parts evenly coated with sealant, and then heating to 45-50 degrees C for 20-30 minutes, and then natural drying and curling to obtain condom blank, and (c) subjecting condom blank to swelling, drying, testing and vacuum packaging treatment to obtain final product.
