Problems solved by technology

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 protective agents.
This results in a slower rate of forming an effective protective film on the stone surface, a longer effective time than oil-based protective agents, and higher requirements for the temperature of the construction environment
For example, in the northern region or in the low temperature environment in winter, the application of water-based stone protective agent will be greatly restricted

Abstract

The invention discloses an ultraviolet curing water-based stone protective agent for stone surface protection. The protective agent is prepared from the following components: ultraviolet curing film-forming resin, a photoinitiator, a polyphosphoric acid type dispersing agent, an organic silicon type antifoaming agent, a film-forming additive and solvent water. By adopting a light curing resin technology, the film-forming speed of the water-based stone protective agent is greatly increased, the protective effect of the water-based stone protective agent is greatly improved, original advantagesof the water-based protective agent are kept, furthermore, the effectual-time of curing is greatly shortened, and the construction efficiency can be obviously increased; furthermore, the protective construction operation can also be performed under a low-temperature or high-humidity environment, thereby widening the adaptability of the water-based stone protective agent in the prior art; and the problems of the water-based stone protective agent in the prior art that the rate of forming an effective protective film on a stone surface is lower, the effect taking time of the water-based stone protective agent in the prior art is longer than that of an oily protective agent, and the requirement for the temperature of a construction environment is higher are solved.

Description

Technical field: [0001] The invention relates to a stone protective agent, in particular to an ultraviolet-curable water-based stone protective agent for stone surface protection 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 st...
