Formula and synthesis method of dimming color particles

Abstract

The invention relates to a formula and a synthesis method of dimming color particles. The formula comprises, by mass, 87-89% of isoamyl acetate, 4-6% of nitrocellulose, 2.5-3.5% of iodine, 1.5-2% of calcium iodide, 0.6-1.6% of methanol and 1.2-2% of pyrazinedicarboxylic acid. The synthesis method comprises the following steps: taking and mixing 87-89% of isoamyl acetate, 4-6% of nitrocellulose, 2.5-3.5% of iodine and 0.6-1.6% of methanol to form a mixture; heating the mixture to 50 DEG C; and adding 1.2-2% by mass of pyrazinedicarboxylic acid into the mixture, and performing a reaction for 1 hto obtain the liquid bipolar dispersed particles. The synthesis method of the dimming color particles has the advantages of simple process, easiness in operation, and suitableness for industrial production, and different colors of the synthesized particles can be determined according to shapes. The prepared liquid bipolar dispersed particles can be applied in a large-area coating manner, so thatintelligent glass can be manufactured in a large area.

Description

technical field [0001] The invention relates to a particle and a synthesis method thereof, in particular to a formula and a synthesis method of a light-adjustable and color-changing particle. Background technique [0002] Color-changing glass refers to the glass that changes color under certain conditions such as light, temperature, electric field or current, and surface pressure, and changes accordingly with the change of conditions. When the applied conditions disappear, it can reversibly and automatically return to the original state. , also known as dimming glass. The color-changing glass changes its own transmission characteristics with the change of the external environment, and can effectively control the solar radiation energy, thereby achieving the purpose of energy saving. Color-changing glasses in the prior art mainly include liquid crystal particle color-changing glass, electrochromic glass, photochromic glass and thermochromic glass. [0003] In the process of...

AI Technical Summary

Problems solved by technology

[0004] The liquid crystal particle color-changing glass in the prior art is to change the alignment of liquid crystal particles and its color and light transmittance, so the response speed is faster, but the light-blocking property is poor; the electrochromic glass uses charge movement to change the internal material, Although the light blocking property is strong, the response speed is slow; photochromic glass uses light to stimulate the silver halide sensitizer in the glass to change color, but the response speed is slow; thermochromic glass uses heat to make the material undergo phase transfer to achieve color change. Purpose, but the response speed is slow; and the maximum manufacturing size of the above-mentioned electrochromic glass, photochromic glass and thermochromic glass is still limited, which cannot meet the needs of the existing technology
