Embodiment 1

[0026] Add 200 grams of deionized water, 800 grams of ethanol, 100 grams of non-oxidized graphene, and 5 grams of nano-calcium carbonate (average particle size: 50 nanometers) to a 2000 ml four-necked flask, and stir and disperse uniformly at room temperature. Then add ionic liquid 10g, stir well and set aside at room temperature. The pH value of the self-healing composite material is tested by precision pH test paper, and the mechanical properties of the material are tested by the national standard GB-T 1040 tensile performance test. The Hopkinson pressure bar is used to measure the piezoelectric response performance of the material under one-dimensional plane wave impact load. After the test, the repair effect is comprehensively evaluated by: poor, unqualified, good, and excellent. The test results are as follows:

[0027]

Embodiment 2

[0029] In a 2000ml four-necked flask were sequentially added 150 grams of deionized water, 850 grams of ethanol, 105 grams of non-graphene oxide, and 5 grams of nano-calcium carbonate (average particle size 60 nanometers), and stirred and dispersed evenly at room temperature. Then add ionic liquid 11 grams, stir well and set aside at room temperature. The pH value of the self-healing composite material is tested by precision pH test paper, and the mechanical properties of the material are tested by the national standard GB-T 1040 tensile performance test. The Hopkinson pressure bar is used to measure the piezoelectric response performance of the material under one-dimensional plane wave impact load. After the test, the repair effect is comprehensively evaluated by: poor, unqualified, good, and excellent. The test results are as follows:

[0030]

Embodiment 3

[0032] In a 2000ml four-necked flask, 100 grams of deionized water, 850 grams of ethanol, 180 grams of non-oxidized graphene, and 15 grams of nano-calcium carbonate (average particle size 60 nanometers) were added in sequence, and stirred and dispersed evenly at room temperature. Then add ionic liquid 10g, stir well and set aside at room temperature. The pH value of the self-healing composite material is tested by precision pH test paper, and the mechanical properties of the material are tested by the national standard GB-T 1040 tensile performance test. The Hopkinson pressure bar is used to measure the piezoelectric response performance of the material under one-dimensional plane wave impact load. After testing, the repair effect is comprehensively evaluated by four levels: poor, unqualified, good, and excellent. The test results are as follows:

Abstract

The invention discloses an environment-friendly intelligent mobile phone self-repair material and a using method, and belongs to the field of repair materials.The environment-friendly intelligent mobile phone self-repair material is characterized by being prepared by mixing, by weight, 1-2 parts of graphene, 0.5-2 parts of nano calcium carbonate, 0.5-5 parts of ionic liquid and 100 parts of diluent.The material is the transparent composite material having the certain piezoelectric property and mechanical property.The material is used for repairing a damaged electronic touch screen, can rapidly repair damages and cracks formed by collision and impact on the intelligent mobile phone glass touch screen, is environmentally friendly, has the lasting effect and has no poison effect on intelligent mobile phone users.

Description

Technical field [0001] The invention provides an environment-friendly smart phone self-repairing material and its usage, belonging to the field of repairing materials. Background technique [0002] Smart phones have become the most popular "household appliances" at the moment, with almost one hand. Authorities predict that my country’s smartphone production will exceed 550 million units in 2015. At present, smart phones can replace most of the tasks of computers or laptops, such as browsing the Internet, making friends and chatting, sending and receiving emails, and simply writing materials. Smart phones are generally equipped with glass touch screens, which not only bring us convenience, but also bring us very fragile drawbacks. That is to say, today's smart phones are far from the original feature phones. Smart phone touch screens can be divided into two categories: capacitive and resistive. Although the principles of these two types are different, they are the same in that...
