Problems solved by technology

Mobile phone films in the prior art are generally divided into two categories: high-definition film and tempered film. Among them, high-definition film is generally made of high-definition polymer organic matter, but its hardness is low and easy to scratch. Most mobile phones touch the ground first on the frame (according to the survey, about 75%-80% of mobile phones accidentally drop on the frame first), and there is no special protection technology for the tempered film frame in the prior art

Abstract

The invention discloses a frame bumping-resistant mobile phone tempered membrane and a manufacturing method thereof. The body of the frame bumping-resistant mobile phone tempered membrane comprises, by weight, 85-90 parts of silica, 5-8 parts of boron oxide, 2-3 parts of sodium oxide and 3-5 parts of graphite powder with the particle size being 10-20 [mu]m, and the surface of the body undergoes 80% NaNO3 and 20% KNO3 mixed molten salt ion exchange treatment, wherein a starch modified acrylamide colloid membrane is fixed outside a frame modifying layer. The frame bumping-resistant mobile phonetempered membrane has the advantages of good heat tearing resistance, good toughness, good resistance to surrounding impact, coexistence of the tensile stress and the crushing stress of the surface ofthe frame glass body, and self-buffering performance, and is suitable for frequent falling bumping conditions in fixed frame sizes.

Description

technical field [0001] The invention relates to the field of glass products, in particular to a frame anti-collision toughened film for a mobile phone and a manufacturing method thereof. Background technique [0002] With the development of the times, mobile phones are used more and more frequently. As a high-priced common electrical appliance, the most frequently damaged part is the touch screen of the mobile phone. Therefore, most people use mobile phone film to protect the touch screen of the mobile phone. Mobile phone films in the prior art are generally divided into two categories: high-definition film and tempered film. Among them, high-definition film is generally made of high-definition polymer organic matter, but its hardness is low and easy to scratch. Most of the mobile phones are frame-first (according to the survey, when about 75%-80% of mobile phones are accidentally dropped, the frame first touches the ground), and there is no special protection technology for...
