Abstract

The invention discloses durable interior wall paint. The durable interior wall paint is prepared from the following raw materials in parts by weight: 1.5-3.7 parts of nano-titania, 5-10 parts of titanium dioxide, 20-30 parts of a white emulsion, 6-10 parts of DL-1,4-dithiothreitol, 15-20 parts of deionized water, 2.5-6.3 parts of lauryl aldehyde, 2.5-3.6 parts of sec-octyl phenol polyoxyethylene ether, 2.5-3.7 parts of methyl methacrylate and 3.5-4.2 parts of diphenylboric acid-2-amino ethyl ester. Compared with emulsion paint in the prior art, the durable interior wall paint has the advantages that in the formula design, the emulsion with low VOC and odor is selected, and lauryl aldehyde extracted from plant oil is mainly taken as a film forming agent, so that the organic volatile matter which is harmful to the human body and generated by conventional film forming agents is avoided, and the durable interior wall paint is indeed healthy and environmentally friendly and is harmless to the human body. The durable interior wall paint is applicable to the decoration of public places such as hospitals, schools, office buildings, malls, hotels and the like and is particularly applicable to the decoration of sites where people and equipment cannot be evacuated.

Description

Technical field [0001] The invention relates to a durable interior wall paint and a preparation method thereof, and belongs to the field of architectural coatings. Background technique [0002] With the rapid development of the coating industry, paint home decoration has become more and more common. However, the existing decorative coatings have high free monomer and free formaldehyde content, and contain APEO. After decoration, they often have coughing, sore throat, and unbearable irritating odors, causing serious harm to the human respiratory tract. Summary of the invention [0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a durable interior wall paint and a preparation method thereof, which are environmentally friendly, low in odor, low in production cost, convenient in construction, and strong in adhesion. [0004] In order to solve the above technical problems, the technical solution adopted by the ...
