Problems solved by technology

However, in the prior art, there are relatively high requirements for process parameters such as the type and amount of organic binders, fluidity, and particle size distribution requirements during processing.
And it is easy to cause uneven density distribution of the green body, which may lead to deformation due to inconsistent shrinkage during the sintering process of the finished product, and the performance of the mobile phone case is relatively poor due to the uneven microstructure

Embodiment

[0010] (1) mixing ceramic powder and organic functional additives, making a gelatable ceramic slurry by wet ball milling, and defoaming the gelable ceramic slurry;

[0011] (2) Inject the gelable ceramic slurry after defoaming treatment into the preset mold, and use ultraviolet light to initiate the gelation process to obtain a ceramic mobile phone shell body, and then perform moisturizing treatment on the obtained body, and then Firing to obtain the ceramic mobile phone case;

[0012] (3) Coat the surface of the ceramic mobile phone case with an overglaze color and a graphite layer.

[0013] The ceramic mobile phone case prepared by the preparation method provided in the embodiment of the present invention has high bending strength and high fracture toughness. This is because the method of the present invention does not generate internal mechanical stress during the ceramic molding process, and the internal crystal structure of the obtained ceramic mobile phone case Uniform,...

Abstract

Ceramic mobile phone case, including: ceramic layer, glaze layer, cold catalyst coating and heat conduction film. The invention improves the fracture toughness of the ceramic mobile phone case to a certain extent, so that it has good mechanical properties, bright and rich colors, good self-cleaning effect and strong air purification ability. Moreover, electromagnetic waves can pass through without obstacles, giving full play to the wireless communication performance of mobile phones.

Description

technical field [0001] The invention relates to the field of mobile phone accessories, in particular to a ceramic mobile phone case. Background technique [0002] In recent years, the types of mobile phone cases have been diversified with the increase of mobile phone brands and functions. At present, ceramics have gradually been sought after by consumers due to their beautiful appearance, jade-like luster and smooth feel. favorite. However, in the prior art, there are relatively high requirements on process parameters such as the type and amount of organic binder, fluidity, and particle size distribution requirements during the processing. And it is easy to cause uneven density distribution of the green body, which will cause inconsistent shrinkage and deformation during the sintering process of the finished product, and the performance of the mobile phone case is relatively poor due to the uneven microstructure. Contents of the invention [0003] In order to solve the a...
