Abstract

The invention discloses a self-foaming multi-functional water-based moisture absorption coating and a preparation method thereof. The invention belongs to the field of novel functional coatings. The technical problem that an existing coating is high in heat conductivity coefficient, poor in moisture absorption and high in construction environment requirement is solved. The moisture absorption coating is a double-component water-based coating, wherein a component A mainly comprises powder materials such as hydroxyl fluorine-containing water-based acrylic resin, super absorbent resin and glass beads and multiple functional auxiliaries, and a component B is polyisocyanate. The method comprises the following steps of: pretreating super absorbent resin in water, performing high-speed shearing to obtain micron-sized water-containing particles, dispersing and uniformly mixing the micron-sized water-containing particles with other materials to obtain a component A, and packaging the component A and a component B respectively. The coating disclosed by the invention has a large number of hollow structures, and reduces the temperature difference between pipes, wall boards, equipment surfaces and the like in a humid environment and air, so that the moisture regain phenomenon is prevented. A coating film has a large amount of moisture absorption space, and when the environment humidity is too high, the coating film can absorb water vapor in air and adjust the environment humidity.

Description

technical field [0001] The invention belongs to the field of novel functional coatings, in particular to a self-foaming multifunctional water-based moisture-absorbing coating and a preparation method thereof. Background technique [0002] When the indoor space is small, dark and humid, and the temperature is low and the humidity is high, it is easy for the moisture in the air to return to moisture when it encounters structural surfaces such as pipes, wall panels, and equipment surfaces in the room. The emergence of damp conditions seriously deteriorates the indoor working environment and living environment. It is easy to cause serious consequences such as mildew on the wall, corrosion of metal pipes, and damage to instruments due to moisture. [0003] In a humid environment, methods such as installing a fresh air system can be used to improve the moisture return phenomenon, but the cost is expensive and the project volume is large. Applying moisture-absorbing paint to mois...
