Embodiment 1

[0055]1. Mix 83.97g zirconia, 11.36g deionized water, 2.84g hydantoin epoxy resin, 0.84g ammonium polyacrylate and 0.50g n-octanol, ball mill for 24 hours, add 0.48g curing agent 3,3'-di Aminodipropylamine, after vacuum defoaming treatment, is poured into the preset mold. After curing and forming, the wet ceramic sheet is dried in a liquid medium. The liquid drying method is to place the wet ceramic sheet in ethanol for 24 hours , take out the ceramic thin plate and then carry out heating air drying, the drying system is as follows: the heating rate is 10 ℃ / h, the temperature is raised to the final drying temperature of 80 ℃ and kept for 24 hours, and finally the ceramic green body is obtained.

[0056] 2. Carry out high-temperature sintering treatment to the dried ceramic thin plate green body. The sintering system is as follows: use 1°C / min to raise the temperature to 500°C for 1 hour, and then use 10°C / min to heat up to 1500°C for 2 hours. The sintering equipment is High ...

Abstract

The invention provides a ceramic product and a method for preparing the same by the aid of gel casting technologies on the basis of hydantoin epoxy resin. Gel systems used in the gel casting technologies comprise the hydantoin epoxy resin and 3, 3'-diamino dipropyl amine which is a curing agent. The ceramic product and the method have the advantages that the method is simple and is low in toxicity and short in period, and the large and thin ceramic product which is high in density, excellent in comprehensive performance such as mechanical properties, low in cost and easy to transport and store can be prepared by the aid of the method.

Description

technical field [0001] The invention relates to the field of mobile phone accessory technology and large-size ceramic thin plate wet forming technology, in particular to a ceramic product and a method for preparing the ceramic product using a gel injection molding process based on hydantoin epoxy resin. Background technique [0002] With the development of electronic technology, smart phones have become an indispensable communication tool in people's daily life. Therefore, the requirements for mobile phones are not limited to performance. Thinness, fashion, and beauty have gradually become another important factor in purchasing. Therefore, higher requirements are put forward for the most important accessory of mobile phones - mobile phone cases. [0003] The commonly used materials for mobile phone cases are plastic, metal and ceramics. Although plastic has the advantages of low price, strong plasticity, and easy coloring, its application and development are limited by defe...
