Abstract

The invention discloses a formaldehyde removal and smell elimination interface agent and a preparation method thereof. The interface agent comprises, by mass, 3-8% of polyvinyl alcohol, 1-5% of aromatic polyamine, 1-5% of hydroxyethyl acrylate, 2-10% of a leveling agent, 0.3-0.8% of an organosilicon assistant, 0.5-3% of an antifoaming agent, 1-6% of a water retaining agent, 2-10% of a thickener, 0.1-2% of a viscosity regulator, 1-5% of a transparent filler, and the balance of deionized water. The formaldehyde removal and smell elimination interface agent has excellent performances, and contains no VOCs, formaldehyde, benzene, toluene, xylene, heavy metals or other harmful and toxic substances.

Description

technical field [0001] The invention relates to the field of interface agents, in particular to an interface agent for removing aldehydes and odors and a preparation method thereof. Background technique [0002] Before the building is decorated, there are often many small cracks and pores on the wall surface. In a humid environment, water and the salt it contains will penetrate into the interior of the concrete along tiny cracks and capillary pores, corroding the internal steel bars, causing them to rust and swell, seriously affecting the life of the building. In order to solve these problems, many manufacturers will coat the wall with a layer of interface agent before construction to enhance its surface strength. However, the traditional interface agents on the market only form a layer of film on the surface of the wall, and cannot penetrate into the interior of the wall and combine with the concrete. Although the film layer can block the penetration of water, it is easy ...
