Abstract

The invention provides a hydrophober comprising tridecafluoro octyl trimethoxy silane, ethyl orthosilicate, dodecyltrimethylammonium chloride, isopropanol and ethylic acid. The method for preparing hydrophobic glass comprises the following steps: (1) preparing the hydrophober, taking all the components in a certain proportion, mixing and stiring uniformly; (2) cleaning and drying glass to be processed; (3) spraying the hydrophober prepared in the step (1) on the surface of the glass processed in the step (2); and (4) drying the glass on which the hydrophober is sprayed in the step (3) so that a hydrophobic film layer is dried and solidified to obtain a finished product. The hydrophober has easily obtained components, simple preparation process and good film forming performance and enables the service life of a hydrophobic film to be greatly prolonged; in addition, the acid and alkali resistance and the weather resistance of the prepared hydrophobic glass are greatly improved.

Description

A kind of hydrophober and utilize this hydrophober to prepare the method for hydrophobic glass
Technical field
The invention belongs to the functional glass technical field, relate to a kind of hydrophober, relate to a kind of method of utilizing this hydrophober to prepare hydrophobic glass simultaneously.
Background technology
Because glass surface has higher surface energy, generation surface tension be higher than the surface tension of water far away, so water has infiltrating to glass.Construction work at present and art glass on the home decoration market mostly are by float glass directly or reprocess and form, and all do not have the hydrophobic effect.Therefore, after glass surface is stained with water, can form water membrane, cause water droplet both to be not easy landing, on the other hand, stay stains such as tangible water mark at glass surface after the water droplet drying, not only influence the cleaning frequency that increased again attractive in appearance.Therefore how to improve the glass surface anti-pollution characteristic, reduce cleaning and maintenance difficulties and expense; Improve aspect performances such as glass resistance to acids and bases and weathering resistance, finally improve and improve the glass function value and use value.The report that similar hydrophober was arranged in the past mostly adopts organic silicone oil hydrophobic nature materials such as (like methyl-silicone oils) in their prescription, perhaps adopt general hydrophobic surface promoting agent, but that their shortcoming is the hydrophobic film RT is too short, hydrophobic weak effect etc.
Summary of the invention
The purpose of this invention is to provide the excellent hydrophober of a kind of hydrophobic function.
Another object of the present invention provides a kind of method of utilizing this hydrophober to prepare hydrophobic glass.
Be to realize above-mentioned purpose, the present invention adopts following technical scheme: a kind of hydrophober is grouped into by the one-tenth of following mass percent:
Ten trifluoro octyl group Trimethoxy silanes 0.5～4%
Tetraethoxy 0.1～1.0%
DTAC 0.01～0.2%
Virahol 95～99%
Acetic acid 0.1～0.5%.
Utilize hydrophober to prepare the method for hydrophobic glass, it is characterized in that may further comprise the steps:
(1) preparation hydrophober is got each component in proportion, mixes, and stirs;
(2) with pending glass cleaning, drying;
(3) hydrophober that step (1) is made is sprayed on the glass surface after step (2) is handled;
(4) glass behind baking step (3) the spraying hydrophober gets product the hydrophobic membranous layer dry solidification.
The consumption of hydrophober is in the said step (3): the required hydrophober 3～6g of the glass that every processing is 1 square metre.
Temperature during said step (4) oven dry is 80～180 ℃, and drying time is 1～5 minute.
Stirred 30～60 minutes earlier in the said step (1), ultrasonic agitation is 5～20 minutes then.
When cleaning glass, said step (2) adopts the ultrasonic cleaning agent machine.
Adopt paint finishing during said step (3) spraying.
Each component raw material of hydrophober of the present invention is easy to get, and preparation technology is simple, and moulding property is good, is particularly suitable for industrialized mass production and uses.The present invention adopts the organic fluorine carbon surface active agent---and ten trifluoro octyl group Trimethoxy silanes are as the material that plays the hydrophobic effect; Ten trifluoro octyl group Trimethoxy silanes have superior acid resistance, weathering resistance; Excellent hydrophobic nature; And the group of the functional group of ten trifluoro octyl group Trimethoxy silanes ability itself and glass surface mutually combines, and firmness significantly increases after the film forming, has significantly prolonged the work-ing life of hydrophobic film.
Keep original glass characteristics after using hydrophober of the present invention, also have following advantage simultaneously:
(1) water is at the similar lotus leaf effect of glass surface, is circle and drips a shape, contact angle >=90 °;
(2) make glass surface have the slippage characteristic, make foreign matters such as dust, fingerprint, water mark be easy to remove;
(3) hydrophobic membranous layer delays glass surface and analyses alkali through intercepting air, has effectively prevented the weathering and the mildew phenomena of glass, thereby has prolonged the artistic life-span of glass;
(4) glass behind the spraying nano hydrophobic coat doubles than simple glass on performances such as resistance to acids and bases, weathering resistance.
Based on many characteristics of above hydrophobic glass of the present invention, not only be widely used in the indoor house decoration, like wardrobe door, entry partition, shower house glass metope and mirror etc., also have a wide range of applications in exterior finish such as balcony, curtain wall windows.
