A mildew-proof light-curing water-based stone protective agent for stone surface and preparation method thereof

Abstract

The invention discloses an anti-mildew photocurable waterborne stone protective agent for a stone surface and a preparation method of the anti-mildew photocurable waterborne stone protective agent. The protective agent comprises the following components: UV-curable film forming resin, a photoinitiator, a polyphosphoric acid dispersant, an organic silicon defoaming agent, a film forming auxiliary,a slow-release broad-spectrum anti-mildew bactericide and solvent water. Due to a synergistic effect of a light-curable resin technology and a nano-adsorbent carrier slow release technology, the filmforming speed and protective effect of the waterborne stone protective agent are greatly improved, and the curing effect exerting time is greatly shortened while the original advantage of a waterborneprotective agent is retained, so that the construction efficiency can be remarkably increased; and meanwhile, the protective construction operation can also be realized under a low-temperature or high-humidity environment, so that the adaptability of the waterborne stone protective agent in the prior art is widened, and the antibacterial and anti-mildew properties of the waterborne stone protective agent are remarkably improved while the color, glossiness and light transmitting property of a coating are not affected.

Description

Technical field: [0001] The invention relates to a stone protective agent, in particular to a mildew-proof light-curing water-based stone protective agent for stone surfaces and a preparation method thereof. Background technique: [0002] At present, compared with oil-based organic solvent protective agents, water-based stone protective agents have the advantages of outstanding environmental protection, pollution-free, high safety factor and low price. At the same time, in the actual application process, it can be constructed in the state that the stone is not completely dry, which is much more convenient to use than oil-based protective agents. Therefore, in recent years, water-based stone protective agents have shown an extraordinary development speed. The market Occupancy gradually expanded. However, since the water-based stone protective agent uses water as a solvent, its volatilization rate is much slower than that of the organic solvents used in most oil-based stone p...

Problems solved by technology

After the protective agent has completed the stone protective coating operation, if it is used in a humid and high temperature environment, it will also be attacked by microorganisms and cause large-scale blackening or powdering and peeling, which will affect the beauty of the stone and lose its protective effect on the stone.
