Embodiment 1

[0034] The composition and ratio of the nano-waterproof liquid for electronic products provided in this example are: liquid silicone rubber 1%; 70# alkane solvent oil 94%; Tween 60 0.2%; polyethylene glycol 0.2%;

[0035] Wherein, the above ratios are percentages by mass; at room temperature, the above ingredients are uniformly mixed according to the above ratios to produce the nano-waterproof liquid for electronic products.

[0036] In this embodiment, the 70# alkane solvent oil is a solvent, and the liquid silicone rubber is a waterproofing agent. The Tween 60 and polyethylene glycol are surfactants, respectively surfactant A and surfactant B, and their function is to make the liquid silicone rubber dissolve more fully and more uniformly in the solvent. In the production of waterproof liquid, liquid silicone rubber can be fully and evenly dissolved in the solvent under the action of the above two surfactants at room temperature.

[0037] In the present invention, the water ...

Embodiment 2

[0050] This embodiment is basically the same as Embodiment 1, the difference is that:

[0051] The nano-waterproof liquid for electronic products has the following composition and ratio: liquid silicone rubber 5%; 70# alkane solvent oil 98%; Tween 60 0.6%; polyethylene glycol 0.6%.

Embodiment 3

[0053] This embodiment is basically the same as embodiment one or embodiment two, and its difference is:

[0054] The nano-waterproof liquid for electronic products has the following composition and ratio: 3% liquid silicone rubber; 96% 70# alkane solvent oil; 0.4% Tween 60; 0.4% polyethylene glycol.

Abstract

The invention provides nanometer waterproof liquid for electronic products. The nanometer waterproof liquid comprises, by weight, 1%-5% of liquid silicone rubber, 94%-98% of No.70 alkane solvent oil, 0.2%-0.6% of tween 60 and 0.2%-0.6% of polyethylene glycol. The liquid silicone rubber is used as a waterproof agent, the No.70 alkane solvent oil is used as a solvent, the tween 60 is used as a surfactant A, and the polyethylene glycol is used as a surfactant B. The invention further provides a waterproof method for the electronic products. The waterproof method is implemented by the aid of the nanometer waterproof liquid for the electronic products. The waterproof method includes steps of 1, arranging the electronic products in sealing bins of special nanometer waterproof coating machines for mobile phones; 2, striking the nanometer waterproof liquid for the electronic products by the aid of high-pressure gas, atomizing the nanometer waterproof liquid, ejecting the nanometer waterproof liquid, filling the sealing bins with the nanometer waterproof liquid and converting the nanometer waterproof liquid in a liquid state into waterproof liquid in a nanometer-scale gas state; 3, carrying out vacuum suction, forming a layer of waterproof films from the waterproof liquid in the nanometer-scale gas state and attaching each layer of waterproof films on the surface of each electronic products; 4, volatilizing the solvent, then enabling the nanometer-scale waterproof agent to be in contact with water molecules in air, naturally solidifying the nanometer-scale waterproof agent and ultimately forming the waterproof films.

Description

technical field [0001] The invention relates to a nano-waterproof technology for electronic products, in particular to a nano-waterproof liquid for electronic products and a waterproof method thereof. Background technique [0002] With the development of society, the advancement of science and technology, and the gradual expansion of the electronic product market, the performance requirements of consumers for electronic products are also constantly improving. At present, most electronic products will emphasize their water resistance. However, most of them are waterproof through specially treated mobile phone casings and smart watch casings, which will also have a certain impact on the components of mobile phones and smart watches; and many mobile phones and smart watches, once water enters, the electronic components or circuits inside board will be damaged. [0003] In the prior art, there are published patent documents of nano-waterproof liquid for electronic products a...
