Embodiment 1

[0029] Add 200 grams of deionized water, 800 grams of ethanol, 100 grams of non-oxidized graphene, and 10 grams of nano-calcium carbonate (average particle diameter of 80 nanometers) in a 2000 ml four-necked flask, and stir and disperse evenly at room temperature. Then add 6 grams of ionic liquid A and 3 grams of ionic liquid B, stir evenly and set aside at room temperature. The pH value of the self-healing composite material is detected by precision pH test paper, the mechanical properties of the material are tested by the national standard GB‐T1040 tensile performance test, and the piezoelectric response performance of the material under the one-dimensional plane wave impact load is tested by using the Hopkinson pressure bar. The test and repair effect are comprehensively evaluated by grades of poor, unqualified, good, and excellent. The test results are as follows:

[0030]

Embodiment 2

[0032] Add 150 grams of deionized water, 850 grams of ethanol, 105 grams of non-oxidized graphene, and 5 grams of nano-calcium carbonate (average particle size of 20 nanometers) in a 2000 ml four-necked flask, and stir and disperse evenly at room temperature. Then add 8 grams of ionic liquid A and 2 grams of ionic liquid B, stir evenly and set aside at room temperature. The pH value of the self-healing composite material is detected by precision pH test paper, the mechanical properties of the material are tested by the national standard GB‐T1040 tensile performance test, and the piezoelectric response performance of the material under the one-dimensional plane wave impact load is tested by using the Hopkinson pressure bar. The test and repair effect are comprehensively evaluated by grades of poor, unqualified, good, and excellent. The test results are as follows:

[0033]

Embodiment 3

[0035] Add 100 grams of deionized water, 850 grams of ethanol, 180 grams of non-oxidized graphene, and 15 grams of nano-calcium carbonate (average particle diameter of 100 nanometers) in a 2000 ml four-necked flask, and stir and disperse evenly at room temperature. Then add 6 grams of ionic liquid A and 1 gram of ionic liquid B, stir evenly and set aside at room temperature. The pH value of the self-healing composite material is detected by precision pH test paper, the mechanical properties of the material are tested by the national standard GB‐T1040 tensile performance test, and the piezoelectric response performance of the material under the one-dimensional plane wave impact load is tested by using the Hopkinson pressure bar. The test and repair effect adopts four grades: poor, unqualified, good and excellent to comprehensively evaluate. The test results are as follows:

Abstract

The invention discloses a preparation method of an environment-friendly repair material for an electronic screen of a handheld device and belongs to the field of repair materials. The preparation method of the repair material is characterized by sequentially including the following steps that firstly, by weight, 1-2 parts of graphene and 0.5-2 parts of nano calcium carbonate are added into 100 parts of a diluting agent, and stirring is carried out for uniform dispersion; secondly, by weight, 0.5-5 parts of an ionic liquid mixture is added, stirring is carried out, and the repair material is obtained. By means of the method, the transparent composite material with a piezoelectric property and a certain mechanical property is obtained; when the material is used for repairing a broken electronic screen, breaks and cracks, caused by collision or impact or the like, of the glass touch screen of a smart mobile phone can be rapidly repaired.

Description

technical field [0001] The invention provides a method for preparing an environment-friendly electronic screen repairing material for a hand-held device, belonging to the field of repairing materials. Background technique [0002] In the prior art, handheld devices are very popular, including smart phones, personal digital assistants, portable game consoles, handheld computers, etc. Such devices usually have an electronic display screen and touch input. Electronic display (touch) screens of handheld devices can be mainly divided into capacitive, resistive and other categories according to the principle. Although the principles of these two types are different, the same thing is that the action of pressing the finger on the screen is converted into an electrical signal, which is then sent to the CPU by the controller, and converted to the coordinate value on the screen by the driver, and the click is completed. action and display it on the screen. The traditional way to pro...
