Abstract: The invention discloses a carbon fiber core, which includes a carbon fiber core body. The carbon fiber core body comprises, from top to bottom, a diversion layer, an adhesive layer I, a wrapping layer I, an adhesive layer II, a carbon fiber layer, a fluff pulp layer, a water-absorbent resin layer, an adhesive layer III, and a wrapping layer II. The wrapping layers and the core layer are provided with liquid-permeable and air-permeable holes. On the premise of having a reasonable structure and ensuring absorption performance and anti-reflux performance, the present invention also has excellent deodorizing performance and bacteriostatic performance, and can be applied to incontinence pads and sanitary napkins. In addition, the preparation process of the present invention can realize mass production of the core and applied products, solving the problems of poor production quality and slow production speed existing in the previous sanitary products made of activated carbon.

Abstract: The invention discloses a hydrophobic proppant and a preparation method thereof. The aggregate particles of the hydrophobic proppant are coated with a coating resin which comprises a hydrophobic resin and nano-particles which are uniformly distributed in the coating resin and constitute 5-60% of the coating resin by weight. The contact angle labeled as ? between water and the hydrophobic proppant in which nano-particles are added is in the range of 120°???180°. The proppant of the present invention is prepared by adding the nano-particles in the existing resin in which low-surface-energy substances with hydrophobic groups are added, and a rough surface with a micro-nano structure is constructed on the outer surface of the prepared resin film, so that the contact angle ? at the solid-liquid contact surface on the outer surface of the coating resin of the proppant is more than 120°.
