Problems solved by technology

The Chinese patent application No. 200810222377.6 discloses a kind of indoor coating with humidity control function, which achieves a certain effect by adding humidity control functional materials in conventional paint, but its humidity control effect is limited, such as at 25 ℃, relative humidity Under the condition of 85%, the maximum decrease of relative humidity is 10%RH; after moisture absorption saturation, at a temperature of 25°C and a relative humidity of 35%, the coating will release moisture, and the maximum increase of relative humidity will reach 7%RH
However, there is no coating product with excellent performance in regulating air humidity.

Abstract

The invention discloses a preparation method of paint capable of adjusting air humidity, the paint employs hollow bead, zeolite powder, meerschaum and starch-polyacrylonitrile graft polymers as functional materials for adjusting air humidity, and the raw materials are cooperated with other ingredients to form the paint with good effect for adjusting air humidity. The method aims at the composition characteristic of the paint for limiting the preparation step, and functional ingredients are added by batches step by step, and the prepared paint has excellent performance. According to the invention, under the condition that the temperature is 25 DEG C and the relative humidity is 85%, the relative humidity minimizing amount can reach 25-35%, the test paint has good moisture absorption effect; after saturation through moisture absorption, under the condition that the temperature is 25 DEG C and the relative humidity is 35%, the test paint is capable of releasing humidity, and the relative humidity increasing amount can reach 18-24%.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a preparation method of a coating for adjusting air humidity. 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. [0003] Coatings are closely related to people's daily work, living and other indoor environments, and the use of functional coatings that regulate air humidity can maximize their efficacy. Air-humidity-regulating paint is a new type of functional building decoration material that has emerged in recent years, and domestic scientific researchers have begun to devote themselves to its development and research. Li Shuanglin of Beijing University of Technology prepared a ceramic air humidity regulating coating with organic resin as the functional material for regulating air humidity (Li Shuanglin, Wu Yuting, Ma Chongfan...
