Abstract

The invention discloses a water-based ultraviolet absorbing material. The water-based ultraviolet absorbing material is prepared from the following raw materials in parts by weight: 7-10 parts of pseudo-boehmite, 2-4 parts of nitric acid, 20-30 parts of copper chromite black, 7-11 parts of a dispersing agent, 3-6 parts of aluminum phosphate and 30-50 parts of deionized water. The water-based ultraviolet absorbing material provided by the invention takes pseudo-boehmite and superfine copper chromite black as ultraviolet absorbing main bodies, provides a large specific surface area and greatly improves the ultraviolet absorbing capacity; the pseudo-boehmite is acidified by nitric acid to disperse the copper chromite black better; aluminum phosphate is added as a binder to ensure that a formed water-based ultraviolet absorbing coating is firm and does not fall off; the water-based ultraviolet absorbing material is a safe and environment-friendly water-based coating as no organic solvent is used.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet absorbing materials, and in particular relates to a water-based ultraviolet absorbing material, a preparation method thereof and a water-based ultraviolet absorbing coating formed by the water-based ultraviolet absorbing material. Background technique [0002] Degradation of odorous compounds by releasing ozone through ultraviolet rays has been widely used in industrial production, kitchen degreasing and other fields. Adopting the method that ultraviolet ray releases ozone to carry out degradation, while bringing convenience, also has some disadvantages. For example, the overflowing ultraviolet rays are relatively harmful to human skin and eyes, can cause microvascular expansion, dermatitis, and are also carcinogenic to a certain extent. When ultraviolet rays irradiate the skin, the skin will produce a large number of free radicals, resulting in the peroxidation of the cell membrane, causing ...
