Problems solved by technology

[0002] Doors play a very important role in life, and the existing wooden doors are widely used in the family. However, as people's demand for wooden door functions increases, more and more details need to be dealt with in the process of wooden door processing, and , because the wooden door is made of wood, which is a flammable material. If it encounters a fire, it is very easy to burn. Therefore, how to improve the flame retardant performance of the wooden door is a problem that needs to be solved at present.

Abstract

The invention discloses a preparation method of a flame-retardant low-odor wooden door coating, which comprises the following steps: (1) sequentially adding a polyurethane emulsion, simethicone and avinyl acetate emulsion into a reaction kettle to obtain a preparation body; (2) uniformly dispersing kieselguhr into water glass to obtain a water glass mixed solution, and then adding ammonium phosphate and peroxide into the water glass mixed solution to obtain a kieselguhr composite material; (3) adding hydroxymethyl cellulose into a mixed solution of sulfuric acid and phosphoric acid, and thenadding melamine to obtain a reinforcing material; and (4) sequentially adding the preparation body, the kieselguhr composite material, the reinforcing material, the surfactant, the deionized water andthe defoaming agent into a stirrer, and stirring to obtain the product. According to the preparation method of the flame-retardant low-odor wooden door coating, the water-based coating is adopted, sothat the use of an organic solvent is avoided, the environment-friendly odor is low, and the situation that the organic solvent type coating easily releases a large amount of formaldehyde is greatlyavoided.

Description

technical field [0001] The invention belongs to the technical field of wooden door processing, and in particular relates to a preparation method of a flame-retardant low-odor wooden door paint. Background technique [0002] Doors play a very important role in life, and the existing wooden doors are widely used in the family. However, as people's demand for wooden door functions increases, more and more details need to be dealt with in the process of wooden door processing, and , because the wooden door is made of wooden material, which is a flammable material. If it encounters a fire, it is very easy to burn. Therefore, if the flame retardant performance of the wooden door is improved, it is a problem that needs to be solved at present. Contents of the invention [0003] The purpose of this project is to better store sweet potatoes in the southern region. [0004] The present invention is achieved through the following technical solutions. [0005] A kind of preparation ...
