Problems solved by technology

At present, the UV protection agents or coatings we can see have the following problems, Ti0 2 It has an effective absorption range in UY-B, but the effect in the UV-A band is not good, especially when added to various resins, the anti-ultraviolet effect is not ideal, and it is easy to reunite. Zinc oxide has a better absorption effect in the UV-A band. , but due to the ZnO powder we can see on the market, the agglomeration is serious, the transparency and anti-ultraviolet effect are not very ideal, and it cannot be directly used on architectural glass such as car windshields and home offices.

Abstract

The invention discloses a glass anti-UV paint and a preparation method thereof. The paint comprises the following components: sodium pyrophosphate, 2-ethylhexyl acrylate, methyl oxirane, a surfactant, sodium silicate, zinc oxide, acrylic acid, silica, ethanol and deionized water. The preparation method comprises the following steps: adding sodium pyrophosphate, sodium silicate, zinc oxide and silica in deionized water, heating the materials and adding the surfactant, stirring the materials to obtain mixed liquor 1; then keeping the temperature of the mixed liquor 1 at 50-60 DEG C, adding 2-ethylhexyl acrylate, methyl oxirane and acrylic acid under a stirring state, continuously stirring the materials for 40-50 DEG C to obtain mixed liquor 2; adding ethanol drop by drop in the mixed liquor 2 under room temperature, stirring the materials while adding until the dropping is completed, and then heating the materials and continuously stirring the materials to obtain the glass anti-UV paint. The glass anti-UV paint has adhesiveness and anti-UV performance, and has good visible light permeability.

Description

technical field [0001] The invention belongs to the field of glass surface treatment materials, and in particular relates to a glass anti-ultraviolet coating and a preparation method thereof. Background technique [0002] The energy of ultraviolet light can cause skin aging and even cause skin cancer easily, and it can also cause the fading of various window curtains and floors, plastics and prints. Therefore people pay more and more attention to the harm of anti-ultraviolet radiation, especially the front windshield glass of automobile and door and window glass such as living room, office directly cause harm to people's life. At present, the UV protection agents or coatings we can see have the following problems, Ti0 2 It has an effective absorption range in UY-B, but the effect in the UV-A band is not good, especially when added to various resins, the anti-ultraviolet effect is not ideal, and it is easy to reunite. Zinc oxide has a better absorption effect in the UV-A ban...
