Abstract

The invention discloses a preparation method for a high polymer composite zirconia mobile phone back cover. Mullite whiskers are added to an aqueous solution of ethylene glycol, a suspension is formedthrough uniformly stirring, zirconia powder is added, and a precursor suspension is formed by uniformly mixing; the precursor suspension is transferred to a hydrothermal kettle for reaction to obtainprecursor powder; the precursor powder is transferred to a muffle furnace, the temperature is raised to 1200-1250 DEG C, and the temperature is maintained for 1-2h to obtain mullite whisker toughed zirconia ceramic powder; a polymer is heated to 260-265 DEG C, a filler, plasticizer and the mullite whisker toughened zirconia ceramic powder are added in turn, cutting and mixing are conducted at a high speed to form a viscous body, the viscous body is injection molded into a mold, the temperature is maintained for 6-10 min, warming treatment is conducted, and cooling is conducted to obtain the polymer composite zirconia mobile phone back cover. The method effectively increases the toughness and molding characteristics of the mobile phone back cover.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a method for preparing a high polymer composite zirconia mobile phone back cover. Background technique [0002] The mobile phone has almost become one of the iconic products of modern technology and fashion. The rapid development of mobile phone manufacturing technology has also given birth to the progress of related component manufacturing technology. Among them, the back cover of the mobile phone is one of the main parts of the shape and structure components, and specific and strict technical requirements are also put forward for the performance and quality of the back cover of the mobile phone. As the main supporting part of the mobile phone, the back cover of the mobile phone must have sufficient strength and toughness, and at the same time have good design elements, and it must be easy to manufacture and reuse. Therefore need to develop the mobile phone back cover of vari...
