Description

Light-cured deodorizing sanitary ball and preparation method and application thereof Technical Field The invention relates to the technical field of deodorizing materials, in particular to a deodorizing sanitary ball based on photo-curing and a preparation method and application thereof. Background The products for deodorizing and cleaning urinals and toilets in public places in the market at present mainly comprise solid cleaning blocks formed by traditional pressing or casting, and the base material of the solid cleaning blocks is usually water-soluble polymer (such as PEG) or inorganic salt/surfactant mixture. The microstructure of the obtained base material is always uniform by adopting fusion casting or high-pressure compression molding, so that the release rate of the active ingredient is difficult to accurately regulate and control, the problems of initial burst release and sudden drop of the later effect often occur, the effective service life is shortened, and the maintenance cost is increased. The traditional casting method needs high temperature, is easy to volatilize and degrade heat sensitive components such as natural essential oil, especially can crack the shell of the long-acting slow-release microcapsule essence to fail, and the pressing method is carried out at normal temperature, but is difficult to form a compact high-strength structure. In addition, the existing PEG or surfactant base material has insufficient mechanical strength and water flow scouring resistance, and under the high-frequency and strong-water flow scouring environment in public places, the product is easy to be dissolved too fast, disintegrated or disintegrated in structure, further accelerates the loss and possibly causes the blockage of sanitary ware. On the deodorization mechanism, the existing cleaning products mostly depend on a single mode of organic acid salification neutralization and fragrance masking, so that the deodorization is not thorough. Based on this, there is a need to develop a cleaning product with high strength, high efficiency in deodorizing, and precise slow release of fragrance. Disclosure of Invention Aiming at the problems existing in the prior art, the invention aims to provide a deodorizing sanitary ball based on photo-curing and a preparation method thereof, wherein the sanitary ball forms a high-strength and high-crosslinking three-dimensional network skeleton by an acrylic ester prepolymer system through photo-polymerization, so that the water scouring resistance and the structural durability are remarkably improved, the problem that the traditional material is easy to disintegrate is solved, the damage to heat-sensitive components caused by high temperature is avoided by adopting a normal-temperature photo-curing process, and the multiple effects of catalysis, neutralization and slow release can be realized by adding solid organic active substances, MOF catalytic filler and microencapsulated aromatic into the sanitary ball, so that the service life of a product is prolonged while the high-efficiency and lasting deodorization is ensured.
