Problems solved by technology

However, these products have more or less disadvantages: the moisture analysis of silica gel shows a serious hysteresis phenomenon; the moisture capacity of montmorillonite is small; Humidity materials have a small amount of moisture release and a slow rate of moisture release; some new humidity-conditioning materials have complicated manufacturing processes and high production costs
However, there is no paint product with excellent humidity control performance and low price.

Abstract

The invention provides internal wall decorative paint with the function of adjusting air humidity and a construction method thereof, belonging to the building material field. The paint in every 100 weight portion at least comprises 15 to 45 weight portions of a material with the function of adjusting the humidity. The internal wall decorative paint takes a porous inorganic mineral material such as sepiolite, diatomite and attapulgite as the material with the function of adjusting the humidity, is applied to the building internal wall paint, and is matched with the corresponding paint construction process. The paint construction process comprises the following steps: a substrate is polished and leveled and keeps clean and dry firstly; secondly, the paint is sprayed on the internal wall surface by a spray gun with a large-caliber nozzle of 2.5 millimeters, and the thickness of a coat is between one and two millimeters so that the paint can effectively adjust the indoor air humidity as well as has the function of decorating and the indoor air humidity is controlled within the range beneficial to the human body health; meanwhile, the paint does not pollute the environment, and has zero VOC emission. The construction process ensures that the paint effectively fulfills the humidity adjusting function aiming at the characteristic of the humidity adjusting function of the paint.

Description

technical field [0001] The invention relates to building decoration materials, in particular to a functional interior wall paint and a construction process thereof. Background technique [0002] Air relative humidity is an important parameter to measure the indoor environment, which is of great significance to human health, indoor air quality and storage of articles. Japanese scholar Nishito Miyano first proposed the concept of "humidity control materials". In recent years, humidity control materials have gradually developed, and humidity control products cover building materials, textiles and other fields. [0003] Japan has been at the forefront of the world in the development and application of humidity control materials. In recent years, Japan has obtained a number of patents on humidity control materials, mainly mixing commonly used special silica gel, montmorillonite, inorganic salts, organic polymer materials and other humidity control materials into other materials ...
