Description
Technical field
The present invention relates to a kind of dirt-resisting dustproof electronic device technology, relate in particular to a kind of manufacture method of dirt-resisting dustproof electronic device.
Background technology
Electronic product has been widely used in routine work and the life, and various electronic products are along with the increase of service time, and dust and dirt can be adhered in its surface, thereby influence attractive in appearance.Angle from microcosmic, why dirt and dust can be attached on the electronic products, mainly be because have many micro-pores not of uniform size on the electronic product surface, and the size of part dirt and dust particle is less than the size of micro-pore on the electronic product surface, thereby cause dirt and dust easily attached in the hole on electronic product surface and cause polluting, therefore as improving the ability of electronic product dirt-resisting dustproof, just must effectively repair or fill up the hole on electronic product surface.
The TaiWan, China patent announcement has disclosed a kind of nanoscale dirt-resisting dustproof method for No. 562790, and this dirt-resisting dustproof method utilizes hydrolysis-condensation reaction to make nano material silica; With isopropyl alcohol this nano material is diluted to suitable concentration then; Nano material after will diluting again is sprayed on the surface of ceramic product; After the spraying ceramic product placed in the baking box earlier that the heating rate with 0～2 ℃ of per minute is heated to 150～200 ℃, the constant temperature baking is 20 minutes to 1 hour again; With the rate of temperature fall of 0～1.7 ℃ of per minute the temperature in the baking oven is reduced to below 70 ℃ subsequently, then product is taken out, thereby form a diaphragm, to reach dirt-resisting dustproof and easy cleaned effect on the ceramic product surface.Yet this dirt-resisting dustproof method need adopt the method for high temperature heating to form diaphragm, not only increases energy consumption, and easy performance because of the temperatures involved electronic product.
Summary of the invention
The objective of the invention is provides a kind of manufacture method that cuts down the consumption of energy and do not damage the dirt-resisting dustproof electronic device of electronic product performance at the defective that above-mentioned prior art exists.
For achieving the above object, the manufacture method of dirt-resisting dustproof electronic device of the present invention comprises the steps:
Step 1 utilizes sol-gal process to make the nano-metal-oxide colloid initial reactant;
Step 2 will be made nano-metal-oxide colloid dilution and be coating sizing-agent, and this coating sizing-agent left standstill make it form nano coating liquid;
Step 3 is uniformly coated on nano coating liquid on the surface of electronic installation;
Step 4, the at room temperature dry diaphragm that forms of the nano coating liquid that electronic installation is coated with.
As mentioned above, the manufacture method of dirt-resisting dustproof electronic device of the present invention is by being uniformly coated on nano coating liquid on the electronic installation surface and at room temperature making the nano coating liquid drying, thereby form the diaphragm of a nano material on electronic installation surface surface, and then utilize the character of nano material to reach the effect of dirt-resisting dustproof; And nano coating liquid air dry at room temperature and form diaphragm in the manufacture method of this dirt-resisting dustproof electronic device, thus capable of reducing energy consumption, and do not damage electronic product performance.
The specific embodiment
One-tenth purpose and effect for describing technology contents of the present invention, structural feature in detail, being reached are described in detail below in conjunction with embodiment.
The manufacture method of dirt-resisting dustproof electronic device of the present invention comprises the steps:
Step 1 selects suitable initial reactant to utilize the Prepared by Sol Gel Method method to prepare the nano-metal-oxide colloid, and initial reactant can be various metal alkoxides, and it can make various nano-metal-oxides respectively;
Step 2 is that nano-metal-oxide colloid percentage by weight is 30% coating sizing-agent with alcohols solvent with Manufactured nano-metal-oxide colloid dilution, and this coating sizing-agent was left standstill 24 hours that coating sizing-agent is stablized becomes a kind of nano coating liquid;
Step 3 is coated on the mode of nano coating liquid with spraying, immersion or wiping on the surface of electronic installation equably, makes nano coating liquid fill up the micro-pore on electronic installation surface effectively and forms a successional film on the surface of electronic installation;
Step 4 places the electronic installation that is coated with nano coating liquid to make the nano coating liquid air dry under the room temperature, thereby forms a successional diaphragm on the electronic installation surface.
Further specify the present invention with a non-limiting embodiment below:
The initial reactant that uses in the present embodiment is silane compound, obtain the nanometer titanium dioxide colloidal silica with this silane compound with Prepared by Sol Gel Method, be that the percentage by weight of nanometer titanium dioxide colloidal silica is 30% coating sizing-agent with the ethanol kind solvent with the dilution of this nanometer titanium dioxide colloidal silica then, and this coating sizing-agent left standstill made its stable nano coating liquid that becomes in 24 hours; Nano coating liquid is coated on half area of two white substrate surfaces respectively in the wiping mode, uncoated this nano coating liquid of second half of this white substrate surface, wherein a white substrate places under 105 ℃, make the nano coating liquid drying, thereby formation one thickness is 17 microns diaphragm on white substrate, to make first sample; Another white substrate being placed make the nano coating liquid air dry under the room temperature, is 17 microns diaphragm thereby form a thickness on this white substrate, to make second sample.
Counterweights with 500 grams are positioned on first sample and second sample respectively, and the surface contact that first sample and second sample is coated with nano coating liquid is full of the ground of dust and dirt, and drags back and forth 20 times.First sample is after dragging, and this white substrate surface is coated with nano coating liquid one side does not almost have dust and dirt to adhere to; And uncoated how rice coating fluid one side is stained with a large amount of dusts and dirt.Second sample is after dragging, and this white substrate surface is coated with nano coating liquid one side does not almost have dust and dirt to adhere to; And uncoated nano coating liquid one side is stained with a large amount of dusts and dirt.Empirical tests learns that the dirt-resisting dustproof function of the diaphragm that dry diaphragm that forms and heat drying form under the room temperature is suitable.
As mentioned above, the manufacture method of dirt-resisting dustproof electronic device of the present invention is by being uniformly coated on nano coating liquid on electronic installation surface and how at room temperature making rice coating fluid drying, form the diaphragm of a nano material on electronic installation surface surface, thereby utilize the character of nano material to reach the effect of dirt-resisting dustproof; And nano coating liquid is can be at a lower temperature dry and form diaphragm in this method, thereby cuts down the consumption of energy, and does not damage electronic product performance.
