preparation example Construction

[0040] The preparation method of above-mentioned glass easy-clean liquid comprises the following steps:

[0041] Step S110 , mixing the organosilicon monomer and the organotin catalyst and then heat-treating to a temperature of 55° C. to 80° C.

[0042] In one embodiment, the organosilicon monomer and the organotin catalyst are added into the reactor in batches, and the temperature is gradually raised to 55° C. to 80° C. under stirring. Further, the time for gradually increasing the temperature under stirring is 30 minutes to 60 minutes. Further, the organosilicon monomer and the organotin catalyst are simultaneously added into the reactor and stirred.

[0043] Step S120, at a temperature of 55° C. to 80° C., continue to add the remaining components and react for 2 h to 6 h.

[0044] In one embodiment, at a temperature of 55° C. to 80° C., the remaining components are continuously added and reacted for 2 hours to 6 hours, and then cooled to obtain a glass easy-cleaning liqui...

Embodiment 1

[0069] The raw materials for preparing the glass easy-to-clean solution of this embodiment include by mass percentage:

[0070]

[0071]

[0072] According to the proportions of the above-mentioned components, the glass easy-cleaning liquid is prepared. The preparation steps are as follows: measure and weigh isobutyltriethoxysilane and dibutyltin diacetate according to the proportions of the components, add them to the reaction kettle in 3 times, and stir Gradually raise the temperature to 55°C, stir for 0.5h, then add the remaining components into the reaction kettle, and keep the reaction temperature at 55°C, and the reaction time is 6h, and the glass easy-cleaning liquid is obtained after cooling.

[0073] The prepared glass easy-cleaning liquid is evenly coated on the surface of a clean and dry glass substrate by spraying equipment, wherein the glass substrate used is soda calcium fully tempered glass with a thickness of 3mm. The uniformity of the sprayed hydrophobic...

Embodiment 2

[0076] The raw materials for preparing the glass easy-to-clean solution of this embodiment include by mass percentage:

[0077]

[0078] According to the proportions of the above components, the glass easy-cleaning solution is prepared. The preparation steps are as follows: measure and weigh methyltriethoxysilane and stannous octoate according to the proportions of the components, add them to the reaction kettle in 3 times, and gradually heat up under stirring. to 80°C, stirred for 0.5h, then added the remaining components into the reaction kettle, and kept the reaction temperature at 80°C, the reaction time was 2h, and the glass easy-cleaning liquid was obtained after cooling.

[0079] The prepared glass easy-cleaning liquid is evenly coated on the surface of a clean and dry glass substrate by spraying equipment, wherein the glass substrate used is soda calcium fully tempered glass with a thickness of 6 mm. The uniformity of the sprayed hydrophobic and easy-to-clean coatin...

Abstract

The invention relates to an easy glass cleaning liquid and a preparation method thereof, as well as easily cleaned glass and a preparation method and an application thereof. The easy glass cleaning liquid is prepared from the raw materials in percentage by mass: 40-65% of an organic silicon monomer, 10-20% of a first silane coupling agent, 5-15% of a second silane coupling agent, 0.1-2% of an organic tin catalyst and 5-20% of a crosslinking agent. The first silane coupling agent is selected from at least one of gamma-aminopropyltriethoxysilane and N-(beta-aminoethyl)-gamma-aminopropyltriethoxysilane; the second coupling agent is gamma-glycidyl ether aminopropyltriethoxysilane. The easy glass cleaning liquid can be reacted with active hydroxyl functional groups on the surface of glass to form chemical covalent bonds, so that a formed lyophobic coating is high in adhesion, relative good in ultraviolet resistance and heat-resistant stability on the surface of the glass, and has the effects of low surface energy, relatively good hydrophobic and self-cleaning effects of the organic silicon material, so that excellent weather resistance of the easily cleaned glass is endowed, the outdoorlong-term using demand is met, and the glass is also endowed with a remarkable hydrophobic easy-cleaning effect.

Description

technical field [0001] The invention relates to the technical field of glass cleaning, in particular to glass easy-cleaning liquid and its preparation method, easy-cleaning glass and its preparation method and application. Background technique [0002] The cleaning problem of curtain wall glass has been bothering people all the time, and it also affects the city appearance at the same time, so far there is no good solution. In order to solve the cleaning problem of curtain wall glass, people began to coat the glass surface, easy-clean glass is one of them, and easy-clean glass is usually called self-cleaning glass vividly in business After a layer of special paint is applied on the glass surface, it is difficult for dust or dirty liquids (including water-containing and even oil-containing liquids) to adhere to the surface of the glass, or it is relatively easy to be washed away by rainwater under the action of natural forces, so that the glass surface is very It is easy to ...
