Abstract

The invention discloses durable interior wall coating, which is prepared from the following raw materials in parts by weight: 5 to 8 parts of bentonite, 2.5 to 6.3 parts of 2,5-dichloro-alpha, alpha, alpha-trifluorotoluene, 10 to 15 parts of deionized water, 20 to 25 parts of white glue, 3.5 to 7.6 parts of 3,5,5-trimethyl hexanal, 3.5 to 7 parts of octadecyl alkyl alcohol polyoxyethylene ether, 4.2 to 6.5 parts of 11-bromo-1-undecanol, 2.3 to 4.6 parts of hydroxymethylurea and 1.5 to 3.2 parts of boronic acid. Compared with the existing emulsion paint, in a formulation design, the main invention of the durable interior wall coating disclosed by the invention adopts the octadecyl alkyl alcohol polyoxyethylene ether as a coalescing agent besides choosing the white glue which is low in VOC (volatile organic compound) and less in odour, so that the VOC, harmful to a human body and brought about by a conventional coalescing agent, is avoided, and health and environment protection and no-harm to the human body can be really achieved. The durable interior wall coating is suitable for decoration of public places such as hospitals, schools, office buildings, malls, hotels and the like, and in particular for the decoration and fitment of places that personnel and equipment cannot be evacuated.

Description

technical field [0001] The invention relates to a durable 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 a durable interior wall paint and a preparation method thereof, 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 technical problems, the technical solution adopted by the presen...
