Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a method for preparing an easy-to-clean coating provided by an embodiment of the present application is shown, including:
s110, reacting nano silicon dioxide, alkyl silane, non-alkyl silane, a solvent, water and a catalyst according to a preset ratio under a first preset condition to obtain a reaction product;
s120, carrying out reduced pressure distillation on the reaction product under a second preset condition to obtain a film forming substance;
s130, uniformly mixing 100-200 parts by weight of the film-forming material, 20-50 parts by weight of filler, 50-100 parts by weight of pigment and 0.1-2 parts by weight of auxiliary agent to obtain the easy-to-clean coating.
In the embodiment of the application, nano silicon dioxide, alkyl silane, non-alkyl silane, solvent, water and catalyst are reacted according to a preset proportion under a first preset condition to obtain a reaction product; carrying out reduced pressure distillation on the reaction product under a second preset condition to obtain a film forming substance; uniformly mixing 100-200 parts by weight of the film-forming material, 20-50 parts by weight of the filler, 50-100 parts by weight of the pigment and 0.1-2 parts by weight of the auxiliary agent to obtain the easy-to-clean coating, wherein the easy-to-clean coating has better waterproof and stain-resistant performance, wear resistance and high temperature resistance, can be used in an oil pollution environment and a high temperature environment, is not easy to soften and fall off, has higher surface hardness and is not easy to cause scratching.
Next, a method for producing an easy-to-clean coating material in the present exemplary embodiment will be further described.
In step S110, nano-silica, alkyl silane, non-alkyl silane, solvent, water, and catalyst are reacted at a predetermined ratio under a first predetermined condition to obtain a reaction product.
Reacting 1-10 parts by weight of nano silica, 100-200 parts by weight of alkyl silane, 5-30 parts by weight of non-alkyl silane, 50-100 parts by weight of solvent, 5-20 parts by weight of water and 0.01-0.5 part by weight of catalyst at the temperature of 45-65 ℃ for 4-8h to obtain the reaction product.
It should be noted that, when the amounts of the nano-silica, the alkylsilane, the non-alkylsilane, the solvent, the water and the catalyst are in the above ratio, the reaction speed of the system is suitable, and the water-proof stain-resistant property, the wear-resistant property and the high-temperature resistance of the easy-to-clean coating are better. If the dosage of the nano silicon dioxide is too large, the crosslinking density of the system is too large, the viscosity of the film forming material is too large, the later construction is not facilitated, and if the dosage of the nano silicon dioxide is too small, the effects of improving the wear resistance and the thermal stability can not be achieved. If the amount of the alkylsilane and the non-alkylsilane is too large, the manufacturing cost is significantly increased, and if the amount of the alkylsilane and the non-alkylsilane is too small, the effect of improving the waterproof and stain-resistant properties is not achieved. If the solvent dosage is too large, the later-stage removal is difficult, the manufacturing cost is increased, and if the solvent dosage is too small, the effect of reducing the viscosity of the system cannot be achieved. If the amount of water used is too large, the crosslinking reaction of the system becomes too fast and gelling tends to occur, and if the amount of water used is too small, the reaction of the system tends to be insufficient. If the amount of the catalyst used is too small, the reaction rate is low and the production efficiency is low, and if the amount of the catalyst used is too large, the reaction of the system is too fast and gelation is likely to occur.
And as described in step S120, distilling the reaction product under a second preset condition to obtain a film-forming substance.
