Flame-retardant water-based interior wall coating and preparation method thereof

Abstract

The invention discloses flame-retardant water-based interior wall coating and a preparation method thereof. The coating is prepared from the following raw materials by weight: 0.1-0.3 part of triethylamine, 1-2 parts of ammonium persulfate, 40-50 parts of sodium acrylate, 180-200 parts of silicone-acrylic emulsion, 3-5 parts of phosphorus trichloride, 1-2 parts of triglycidyl isocyanurate, 10-15 parts of expanded perlite powder, 3-6 parts of zinc borate hydrate, 4-6 parts of pentaerythritol, 0.01-0.02 part of p-methylbenzene sulfonic acid, and 0.8-1 part of 2-mercaptobenzimidazole. The expanded perlite powder added in the coating can effectively promote the formation of the expanded carbon layer, and zinc borate hydrate has a good flame-retardant effect, and the introduced phosphate has agood synergistic flame-retardant property.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a flame-retardant water-based 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 inorg...

[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;
