Abstract

The invention provides an indoor waterproof emulsion paint and a preparation method of the indoor waterproof emulsion paint, and relates to the field of paints. The indoor waterproof emulsion paint isprepared from the following raw materials by weight: 40-50 parts of polysiloxane-polyurethane emulsion, 3-5 parts of cellulose, 30-40 parts of talcum powder, 8-16 parts of a coalescing agent, 5-8 parts of polyvinyl alcohol, 3-5 parts of a defoamer, 3-5 parts of vegetable protein, 15-20 parts of hollow glass microsphere, 10-15 parts of deionized water, and 40-50 parts of lotus leaf. The inventionprovides the indoor waterproof emulsion paint and the preparation method of the indoor waterproof emulsion paint, the emulsion paint is relatively strong in hydrophobic property, so that the waterproof effect is achieved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an indoor waterproof latex paint and a preparation method thereof. Background technique [0002] Latex paint is a common name for latex paint. It was born in the middle and late 1970s. Latex paint has many advantages compared with traditional wall paint, such as easy to paint, fast drying, and good scrub resistance. However, if the existing latex paint is placed in a humid environment for a long time, the paint surface of the latex paint will easily become moldy and black, which will bring a lot of inconvenience to the decoration, and will cause the paint surface to come off, and even emit harmful substances and unpleasant smells. Contents of the invention [0003] The object of the present invention is to provide a kind of indoor waterproof latex paint and preparation method thereof, to solve the above technical problems. [0004] In order to solve the problems of the technologies des...
