Abstract
The invention provides a reactive nano-silica waterproof liquid for electronic products, and a waterproof method thereof. The waterproof liquid comprises 45-55wt% of ethyl orthosilicate, 20-30wt% of modified silicone oil, 1-5wt% of dibutyltin dilaurate, 1-10wt% of hydrochloric acid and 1-10wt% of triethanolamine, and also comprises a solvent, and the proportion of the solvent is determined by the physical states and contents of above ingredients. The waterproof liquid has the advantages of cheap and simple raw materials, and easy large-scale production, and waterproof materials produced by using the waterproof liquid have good performances.
Description
Technical field
The present invention relates to the nano water-proof technology of electronic product, be specifically related to a kind of high-end electronic product reaction type nm silicon-dioxide Water-proof liquid.
Background technology
Along with the development of society, the progress of science and technology, the progressively expansion of mobile phone market, human consumer is also constantly improving the performance requriements of mobile phone.The continuous functionalization of mobile phone, intelligentized while, start to pursue hommization, such as waterproof.Due to functionalization and intelligent development on mobile phone, human consumer can play mobile phone whenever and wherever possible, by bus, walk, have a meal, when working all with mobile phone, even go to toilet, when having a bath also with mobile phone.But mobile phone is dropped to inside toilet, pond because of carelessness with mobile phone having a bath, when going to toilet, such mobile phone can be intake, and causes mobile phone short circuit to break down.Businessman is in order to satisfy the demands of consumers thus, is proposed six anti-mobile phones, anti-electrostatic, wear-resisting, waterproof, protection against the tide, mildew-resistant, fungi-proofing.But existing waterproofing design is all by design structurally, carries out sealing from structure and arrange, such as increase the stopping property etc. of shell, to increase the stopping property of mobile phone, reach waterproof effect.But this design outline deficiency attractive in appearance, heavy, and for manufacturer, add design and die cost, and easily because of structural damage, as produced slight crack or scarce block etc., and lose water-repellancy.
Chinese patent CN 104559792 A openly knows clearly a kind of use for electronic products Nano waterproof paint, and it comprises the component of following parts by weight: nanometer fluoropolymer particles will 25-65; Polysiloxane 0.05-10; Urethane 4-20; Tasteless solvent 30-75; Wollastonite fibre 1-20; Nano titanium oxide 0.2-10; Nano zine oxide 0.5-10.The invention also discloses the electronic product nano water-proof method adopting described coating, comprise the steps: 1) Nano waterproof paint is sprayed onto on electronic component that electronic product contacts with air, coat-thickness is 0.15-0.25mm; 2) under the condition of 40-60 DEG C, by the electronic product baking 2-3 hour sprayed, electronical elements surface is made to form the fish tail and waterproof layer of layer of transparent.
But should still prepare burden and produce too complicated by this product, and cause cost very high; Its tight zone precision formed for electronic product surface is not high, causes high-end scientific and technological mobile phone, camera, high-end line plate to safeguard that water-repellancy and outward appearance all do not reach ideal effect.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art part, the object of the present invention is to provide a kind of batching and processing use for electronic products reaction type nm silicon-dioxide Water-proof liquid that is simple, good waterproof performance, to overcome defect of the prior art.
To achieve these goals, the invention provides a kind of use for electronic products reaction type nm silicon-dioxide Water-proof liquid, its composition and proportioning are:
Above per-cent is all weight percentage, and wherein, described use for electronic products reaction type nm silicon-dioxide Water-proof liquid also comprises solvent, and solvent burden ratio is fixed with the physical condition of above-mentioned batching and water content.
A kind of electronic product waterproof method, uses above-mentioned use for electronic products reaction type nm silicon-dioxide Water-proof liquid, comprises the steps:
1), by Water-proof liquid be sprayed onto on electronic component that electronic product contacts with air, coat-thickness is 0.0001-0.0004mm;
2) electronical elements surface, is made to form the nano level silicon-dioxide fish tail and waterproof layer of layer of transparent.
As can be seen here, the invention provides and the invention provides a kind of use for electronic products reaction type nm silicon-dioxide Water-proof liquid, its composition and proportioning are: tetraethoxy 45%-55%; Modified silicon oil 20%-30%; Dibutyl tin dilaurate 1%-5%; Hydrochloric acid 1%-10%; Trolamine 1%-10%; Above per-cent is all weight percentage, and wherein, described use for electronic products reaction type nm silicon-dioxide Water-proof liquid also comprises solvent, and solvent burden ratio is fixed with the physical condition of above-mentioned batching and content.Cheaper starting materials of the present invention is simple, easily scale operation, and the water-proof material performance of production is better.
