Description

Technical Field

[0001] The invention belongs to the technical field of indoor coatings, and in particular relates to a plant interior wall paint and a preparation method thereof. Background Art

[0002] At present, the materials of interior decoration wall coatings are composed of chemicals and chemical products, which can meet various national standards, but ultimately cannot meet the real environmental protection requirements.

[0003] Prior art CN 104893575 A discloses an ecological plant environmentally friendly wall paint, which is composed of 20-40% plant vine glue, 20-40% kaolin, 20-30% acrylic emulsion, 5-8% refined tung oil, 0.3-0.5% dispersant, 0.2-0.4% wetting agent, 0.1-0.2% defoamer and 5-10% titanium dioxide by weight, and the sum of each component is 100%; the plant vine glue is kiwi vine glue, which is obtained by crushing fresh kiwi vines and soaking them in water. The paint product of this invention uses kiwi vine glue, and the paint produced is durable and does not decompose. However, this patent only uses one plant glue (kiwi vine glue), and most of the components of the paint still rely on various chemical and traditional chemical products on the market, such as acrylic emulsion.

[0004] Prior art CN 112111204 A discloses a Chinese herbal plant interior wall paint; the Chinese herbal plant interior wall paint is composed of hawthorn, pyrrosia, plantain seed, tangerine peel, coltsfoot flower, sterculia lychnophora, fritillaria cirrhosa, bitter almond, platycodon, asarum, siler, isatis root, honeysuckle, angelica dahurica, peach kernel, ophiopogon japonicus, American ginseng, raw rehmannia root, clematis root, asparagus cochinchinensis, salvia miltiorrhiza, sappan wood, liuanxiong, licorice, a wetting agent, a drying agent, a mildewproof agent, a defoaming agent, a decolorizing agent, a colorant, a thickener, an acrylic emulsion and a polyvinyl alcohol phosphate resin. The invention uses the medicinal materials as raw materials to crush, boil and mix them to make the interior wall paint. After using the Chinese herbal plant interior wall paint, the digestive function, respiratory tract obstruction and rheumatic diseases can be effectively improved in the long term, and indoor pollution can be effectively reduced, and the generation of harmful gases such as formaldehyde can be avoided, and the indoor air has a certain purification effect. However, on the one hand, the components of Chinese medicine decoction have very dark pigments, which are difficult to meet the color requirements of indoor wall paint; on the other hand, Chinese herbal medicine has a strong odor. The smell of Chinese medicine can indeed suppress the odor of other harmful substances, but many consumers find it difficult to accept. Moreover, in essence, the Chinese medicine component is only an additive for the interior wall paint, and the main paint film component is still a chemical product, such as acrylic emulsion and polyvinyl alcohol phosphate resin, so it still cannot meet environmental protection requirements. Summary of the invention

[0005] The purpose of the invention is to provide a plant interior wall paint free of chemical products and a preparation method thereof.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0008] In the present invention, peanut emulsion plays a role in providing flexibility to the coating and preventing cracking of the coating after film formation. Sweet potato glue contains pectin cellulose, which plays a role of viscose in the coating. Kiwi vine glue contains cellulose, which is durable and non-differentiated in the coating, has health care functions and extremely strong weather resistance and adhesion. Glutinous rice glue has extremely strong bonding properties. Potato glue plays a role in replacing heavy calcium and light calcium in conventional coatings in the present invention, and plays a role of preservation and filling. Soybean glue plays a film-forming role in the present invention. Lotus seed glue plays a thickening role in the present invention. Through the synergistic effect of each component, the plant interior wall paint prepared by the present invention not only has good film-forming properties, but also has a higher hardness of the paint film after film formation than ordinary interior wall paints on the market, and completely eliminates the addition of chemical and chemical raw materials used in the original coating, which plays a good health care role for human health.
