Problems solved by technology

This antifouling agent has the following disadvantages: (1) after the antifouling agent is applied to the surface of the polished tile, the petroleum solvent evaporates rapidly into the air and only plays a carrier role, which causes a great waste of resources; (2) ) as a scarce resource, petroleum solvent is expensive, does not conform to the energy-saving and consumption-reducing policy advocated by the state, and will greatly increase product costs; (3) petroleum solvent volatilizes into the air, which will cause certain pollution to the air; (4) Petroleum solvent is a kind of flammable and explosive dangerous goods, which will cause great safety hazards to the transportation and use of products
At present, some manufacturers have used this type of new antifouling agent, but judging from the reflection of the market, there are the following problems: (1) Stability problem
The problem of stability is mainly attributed to two aspects. One is the emulsification of the emulsion itself. Since the formula of this type of antifouling agent is much more complicated than that of organic solvent-based antifouling agents, it is composed of polymer silicone materials and various additives. It is easy to cause demulsification and delamination during storage and use

Embodiment 1

[0029] Take hydrogen silicone oil 10%, hydroxyl silicone oil 3%, methyl silicone oil (350mm 2 ·s ～1 )4%, 107 silicone rubber (10000mm 2 ·s ～1) 2%, emulsifier alkylphenol polyoxyethylene ether (OP-10) 1%, fatty alcohol ether sodium sulfate 0.03% into the reaction pool, slowly add water 78.52% in batches under stirring, and finally add curing agent B Diamine 0.4% and citric acid 1% give a stable emulsion. In order to increase the storage time of the emulsion, a preservative can be added to the emulsion at an amount of 0.05%.

[0030] The emulsion-type ceramic antifouling agent prepared by the above method does not delaminate in a centrifuge at 3000r / min for 20 minutes; the sealed bottled sample can be kept stable in a constant temperature oven at 60°C for one month and outdoors for 6 months state.

Embodiment 2

[0032] Take hydrogen silicone oil 12%, hydroxyl silicone oil 2%, methyl silicone oil (500mm 2 ·s ～1 )5%, 107 silicone rubber (3000mm 2 ·s ～1 )3%, emulsifier fatty alcohol polyoxyethylene ether AEO-3 and AEO-9 respectively 0.3 and 0.8% and sodium dodecylbenzenesulfonate 0.1% were added to the reaction pool, and water was slowly added in batches under stirring 75.75%, and finally add curing agent N-nitrosodiethylamine 0.5% and citric acid 0.5% to obtain a stable emulsion. In order to increase the storage time of the emulsion, a preservative can be added to the emulsion at an amount of 0.05%.

[0033] The emulsion-type ceramic antifouling agent prepared by the above method does not delaminate in a centrifuge at 3000r / min for 20 minutes; the sealed bottled sample can be kept stable in a constant temperature oven at 60°C for one month and outdoors for 6 months state.

Embodiment 3

[0035] Take hydrogen silicone oil 7%, hydroxyl silicone oil 5%, methyl silicone oil (350mm 2 ·s ～1 )2%, 107 silicone rubber (3000mm 2 ·s ～1 )2%, 107 silicone rubber (10000mm 2 ·s ～1 ) 2%, Tween-80 emulsifier 0.4%, Span-80 emulsifier 0.8% and sodium dodecylbenzene sulfonate 0.2% were added to the reaction tank, slowly added water 79.1% in batches under stirring, and finally added N - Nitrosodiethylamine 0.45% and glacial acetic acid 1% to give a stable emulsion. In order to increase the storage time of the emulsion, a preservative can be added to the emulsion at an amount of 0.05%.

[0036] The emulsion-type ceramic antifouling agent prepared by the above method does not delaminate in a centrifuge at 3000r / min for 20 minutes; the sealed bottled sample can be kept stable in a constant temperature oven at 60°C for one month and outdoors for 6 months state.

Abstract

The invention discloses an emulsion type ceramic antifoulant. The emulsion type ceramic antifoulant comprises a high polymer organosilicon material, an emulsifier, a curing agent, an acid restrainer and water. The basic composition and mass fraction of the raw materials are listed as follows: 5-20 percent of hydrogen silicone oil, 2-10 percent of methyl silicone oil, 0.5-5 percent of hydroxyl silicone oil, 2-10 percent of 107 silicone rubber, 0.5-3 percent of emulsifier, 0.2-1 percent of curing agent, 0.2-1 percent of acid restrainer, and the balance of water. According to the invention, the high polymer organosilicon material, the emulsifier, additives and the like are fixed, water is added for emulsification to obtain a stable oil-in-water system; the amine curing agent and the acid restrainer are adopted to greatly improve the antifouling property under the premise of ensuring the stability of the emulsion; and the antifoulant can be used to replace the petroleum solvent type antifoulant and has an extensive application prospect.

Description

technical field [0001] The invention relates to an emulsion type ceramic antifouling agent. Background technique [0002] In recent years, porcelain polished tiles have been widely used in the floor decoration of family rooms and public places. However, due to the fact that porcelain polished tiles are easily adhered to the surface of the tiles by dirt during paving and use, and penetrate into the micropores on the surface of the tiles to cause pollution, affecting the appearance of the polished tiles. In response to this problem, since 2005, a "super clean and bright technology" has been created in the industry. "Super clean and bright technology" is a new technology that uses mechanical pressure to form a nano-scale protective layer with special protective functions and stable structure on the surface of ceramic polished tiles, and finally coats a layer of ceramic antifouling agent of polymer organic silicon . This not only greatly improves the glossiness of the polishe...
