Abstract

The invention discloses an improved interior wall paint. The improved interior wall paint is prepared from the following raw materials by weight: 5 to 8 parts of bentonite, 2.5 to 6.3 parts of copper oxide, 10 to 15 parts of deionized water, 20 to 25 parts of white latex, 3.5 to 7.6 parts of 3,5,5-trimethyl capronaldehyde, 3.5 to 7 parts of stearyl alcohol polyoxyethylene ether, 4.2 to 6.5 parts of vegetable oleic acid, 2.3 to 4.6 parts of carboxymethylcarbamide and 1.5 to 3.2 parts of boric acid. Compared with conventional latex paint, the improved interior wall paint has the following advantages: in a formula, latex with low VOC content and little odor is selected and stearyl alcohol polyoxyethylene ether is mainly used as a film forming aid, so organic volatile matters harmful to the human body in conventional film forming aids are avoided, and the purposes of healthiness, environmental protection and no harm to the human body can be actually achieved. The improved interior wall paint is applicable to decoration of public places like hospitals, schools, office buildings, markets and hotels, especially to decoration and finishing of places where staff and equipment have to stay.

Description

technical field [0001] The invention relates to an improved interior wall coating and a preparation method thereof, belonging to the field of architectural coatings. Background technique [0002] With the rapid development of the paint industry, paint home decoration is becoming more and more common. However, the existing decorative coatings have high content of free monomers, free formaldehyde, and APEO. After decoration, coughs, sore throats, and unbearable pungent odors often occur, causing serious damage to the human respiratory tract. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an improved interior wall paint and its preparation method, which is environmentally friendly, low in odor, low in production cost, convenient in construction and strong in adhesion. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by th...
