Sol inner wall coating and preparation method thereof

Abstract

The invention discloses a sol inner wall coating which is composed of the following raw materials in parts by weight: 130-140 parts of a silicone acrylic emulsion, 3-5 parts of rosinated alcohol, 3-4parts of ricinoleic acid, 0.4-1 part of hexamethylphosphoramide, 1-2 parts of triethanolamine oleic soap, 3-5 parts of aluminum oxide, 4-6 parts of dimethylamine, 0.7-1 part of tetrahydrofurfuryl alcohol, and 0.04-0.1 part of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride. The hollow esterified sol is dispersed by tetrahydrofurfuryl alcohol and then is treated by dimethylamine, and thus an aminated sol is obtained; the silicone acrylic emulsion is treated by ricinoleic acid and then is treated with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride as a carboxyl activator; finally, the obtained product is blended with the aminated sol; through the reaction of acid and amine, the effective compatibility of the hollow esterified sol in the silicone acrylic emulsion is realized, and the uniform stability of the finished product coating is improved effectively.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a sol interior wall coating and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the requirements for buildings are getting higher and higher. At the same time, due to the application of various electrical appliances, indoor fire prevention becomes more necessary. If the inner wall has good fire resistance, when a fire occurs, It will effectively block the external fire source and buy time for escape. At present, in order to improve the fire performance of interior wall coatings, a variety of inorganic fire prevention additives are often added to it, but it is difficult for various inorganic fire prevention additives to achieve synergistic fire protection. As a result, the increase of the fire cannot be prevented from many aspects, and at the same time, due to the addition of inorganic fillers, it is easy to cause ag...

[0002] With the continuous improvement of people's living standards, the requirements for buildings are getting higher and higher. At the same time, due to the application of various electrical appliances, indoor fire prevention becomes more necessary. If the inner wall has good fire resistance, when a fire occurs, It will effectively block the external fire source and buy time for escape. At present, in order to improve the fire resistance performance of interior wall coatings, many kinds of inorganic fire protection additives are often added to it, but it is difficult for multiple inorganic fire protection additives to achieve synergistic fire protection. As a result, the increase of the fire cannot be prevented from many aspects, and at the same time, due to the addition of inorganic fillers, it is easy to cause agglomeration, thereby reducing the mechanical properties of the finished coating;
