Embodiment 1

[0015] A water-based environmentally friendly color-changing paint for a thermos cup, the weight ratio (kg) of each raw material component is: water-based acrylic resin 35, ethylene glycol monobutyl ether 6, n-butanol 6, color changing powder 4, glycerin 2, diffusing agent MF 1. Silane coupling agent Z6040 0.3, dimethyl silicone oil 0.20, deionized water 40.

[0016] The preparation method comprises the following steps:

[0017] (1) Weigh deionized water, put it into the batching kettle, then start the high-speed disperser, and control the speed to 400r / min;

[0018] (2) Weigh water-based acrylic resin, ethylene glycol monobutyl ether, and n-butanol into the batching kettle in turn, continue to stir, and after stirring, put other raw materials into the batching kettle in turn, heat to 80-85°C, and then accelerate stirring Disperse for 40-60min and cool down;

[0019] (3) After dissolving the color-changing powder with deionized water, disperse at high speed for 20-30 minutes...

Embodiment 2

[0022] A water-based environmentally friendly color-changing paint for a thermos cup, the weight ratio (kg) of each raw material component is: water-based acrylic resin 35, ethylene glycol monobutyl ether 6, n-butanol 6, color changing powder 4, glycerin 2, diffusing agent MF 1. Silane coupling agent Z6040 0.3, dimethyl silicone oil 0.20, deionized water 40, adhesive 2. The preparation process is the same as Example 1.

[0023] The adhesive is prepared from the following components by weight (kg): water 15, modified tree ash 2, zinc powder 1, animal glue 2, polyvinyl alcohol 2, N-methyldiethanolamine 2, phosphoric acid Sodium dihydrogen 1, mix the formula raw materials, stir at 80-85°C for 2 hours, after cooling, grind and filter to remove impurities;

[0024] The modified nano tree ash is prepared by the following method:

[0025] (1) Add (1.0-1.2) g / L potassium permanganate solution to soak tree ashes for 2-3 hours, remove, then soak in 12-15% hydrochloric acid solution, a...

Abstract

The invention discloses a waterborne environment-friendly color-changing coating of vacuum cups. The coating is characterized in that the raw material components comprise 35-45 parts of waterborne acrylic resin, 4-6 parts of ethylene glycol butyl ether, 4-6 parts of n-butyl alcohol, 4-6 parts of color-changing powder, 1-2 parts of glycerol, 1-2 parts of diffusant melamine- formaldehyde resin (MF), 0.2-0.3 part of silane coupling agent Z6040, 0.20-0.30 part of simethicone and 40-50 parts of deionized water by weight proportion. After the outer wall of vacuum cups is coated with the coating, the cup body is black before hot water is poured in, patterns appear after hot water the temperature of which is above 20 DEG C is poured in and the cup restores after being cooled. The instantaneous change brings mystery and surprise and delivers endless interest, love and joy.

Description

technical field [0001] The invention belongs to a coating, in particular to a preparation method of a color-changing coating. Background technique [0002] Color-changing thermos cups are also called color-changing cups and phantom cups. After pouring hot water above 20 degrees into the cup, the beautiful and individual patterns printed on the cup body will gradually appear, and everything is as magical as magic. The outside of this kind of thermos cup is coated with temperature-changing paint. However, the current temperature-changing coatings have weak adhesion, and they will fall off and foam after long-term use. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of water-based environment-friendly color-changing paint for a thermos cup. Long-term use will not cause foaming or falling off. [0004] Technical scheme of the present invention is as follows: [0005] A water-based environmentally friendly color-ch...
