Problems solved by technology

This solution can effectively complete the processing and preparation of curved glass, but the toughness of the glass is not good, and the hot bending process leads to stress concentration of the curved glass, and this solution has no other components to absorb impact energy, resulting in all energy being absorbed by the curved glass during the fall , which are more likely to break
[0004] The patent application number 201510651305.3 reports 2.5D glass processing technology, mobile phone glass screen structure and mobile phone. In order to solve the problem of poor drop performance of the 2.5D glass mobile phone back panel, a plastic frame is injected on the edge of the glass back panel to improve 2.5D glass back panel anti-drop performance
However, this solution only has a small amount of plastic frames on the edge to absorb the drop energy, and the drop resistance performance is limited, and it does not improve the drop resistance of the glass itself. At the same time, the plastic frames on the edge are easy to fall off from the glass and affect the appearance.

Abstract

The invention discloses a manufacturing method an of honeycomb-shaped blind-hole toughened glass and application of the manufacturing method. According to the manufacturing method, a plurality of regular polygon-shaped blind holes are precisely carved in the surface of glass, and organic high molecular materials are cured in the blind holes. The blind holes can be used for periodically and locally thinning the glass, and the fracture toughness of the glass is improved, so that an anti-falling property is improved; net-shaped structures, which are not thinned and are communicated on the glass, are mutually connected to improve the strength of a back plate, and the back plate does not become soft due to the relatively thin strength of the glass; the organic high molecular materials are cured, fill the regular polygon-shaped blind holes, and are used for absorbing impact energy in a falling process, so that the fracture toughness of the glass is improved. After the glass is hotly bent, the manufacturing method of the honeycomb-shaped blind-hole toughened glass can be used for preparing a glass mobile phone shell.

Description

technical field [0001] The invention relates to the field of preparation of structural parts, in particular to the field of preparation of consumer electronics backplane structural parts, in particular to a method for manufacturing toughened glass with honeycomb blind holes and its application. Background technique [0002] With the rapid development of consumer electronics such as mobile phones, structural parts such as shells (backplanes) of consumer electronics have made great progress, but also encountered new problems. Especially in the future 5G era, more stringent requirements are put forward for the materials of consumer electronics casings (backplanes). Due to its shielding effect, traditional metal poses a huge challenge to antenna design. It will not be used in the manufacture of 5G casings (backplanes), while plastics are inherently low-strength and non-wear-resistant, which limits their use in large-size screens, ultra- In addition, with the improvement of cons...
