Embodiment

[0030] Step 1. Prepare a mixed solution, introduce 30 parts of toluene and 45 parts of acetone solvent into the reaction kettle, and stir for 5 to 8 minutes. During the stirring process, the temperature can be kept at room temperature. The preparation ratio of toluene and acetone is 1:1.5;

[0031] Step 2: Pour 35 parts of carbon black into the reaction kettle by weighing, mix and stir with the mixed solution for 10-15 minutes, raise the temperature of the reaction kettle to 40 degrees Celsius, and then add 20 parts of polyether polyol into the reaction kettle, The reaction kettle was heated to 45 degrees Celsius and stirred for 5 to 10 minutes, and 0.02 parts of the catalyst was added to the reaction kettle for mixing and stirring to obtain a carbon black mixed solution;

[0032] Step 3: Add 3 parts of titanium dioxide to the reaction kettle after weighing, keep the temperature of the carbon black mixed solution in the reaction kettle at 35-40 degrees Celsius, then add 2 parts...

Abstract

The invention discloses a new high efficiency shading material. The new high efficiency shading material is prepared from the following components by weight: 20-30 parts of polyether polyol, 30-40 parts of carbon black, 30-45 parts of a mixed solvent, 1-3 parts of titanium dioxide, 1-2 parts of isocyanate, 2-4 parts of ceramic micropowder, 2-5 parts of a dispersant, 1-2 parts of an antioxidant, 1-2 parts of an anti-ultraviolet agent, and 0.01-0.03 part of a catalyst. The new high efficiency shading material replaces the traditional shading materials which absorbs ultraviolet light and has poorshading effect, and through proportioning of the ceramic micropowder, isocyanate, polyether polyol and titanium dioxide, the prepared shading material has the effect of reflecting ultraviolet light,so that the irradiating ultraviolet light is blocked outside the shading material by the same in the form of reflection, thus reaching a shading effect, and the raw materials inside the shading material can maintain a stable state of work, the durability of the shading material is increased, and the shading material can maintain a good state for shading.

Description

technical field [0001] The invention relates to the technical field of light-shielding material preparation, in particular to a new material with high-efficiency light-shielding. Background technique [0002] Shading material is a kind of chemical synthesis agent that can absorb ultraviolet rays and prevent ultraviolet rays from penetrating the skin. [0003] Shading materials are widely used in curtains, optical equipment, shading films, etc. Most of the shading materials are liquid and then coated on the surface of objects with equipment to form a shading layer to block sunlight, thereby protecting the equipment from ultraviolet rays. Existing shading During the use of the material, it is exposed to direct sunlight, and some raw materials in the shading layer are oxidized, causing the coating layer to fall off from the surface of the object, making it impossible to block the ultraviolet rays in the sun again. At the same time, after the shading material is prepared, the ca...
