Embodiment 1

[0021] First, 19 parts of black water-based dyes are used for emulsion dyeing of 30 parts of silicone acrylic emulsion and 10 parts of EVA emulsion; the condition is to stir at room temperature at 40°C for 1 hour and rotate at 800 rpm.

[0022] After the above steps are completed, add 34 parts of water, 2 parts of alcohol ester 12, 3 parts of color-fixing agent, 1 part of water-based penetrant, and 1 part of water-based defoamer into the dispersing tank to fully stir and disperse evenly; the condition is 40 ℃ room temperature Stir for 0.5 to 1 hour at a speed of 800 to 1200 rpm. When finished, filter through a 250-mesh filter for later use. The above quantities total 100 servings. The strippable transfer black dye paste can be prepared.

Embodiment 2

[0024] First, 18 parts of blue water-based dyes are used for emulsion dyeing of 35 parts of silicone acrylic emulsion and 15 parts of EVA emulsion; the condition is to stir at room temperature of 40°C for 1 hour and rotate at 800 rpm.

[0025] After the above steps are completed, add 17 parts of water, 8 parts of alcohol ester 12, 5 parts of color-fixing agent, 1.5 parts of water-based penetrating agent, and 0.5 parts of water-based defoamer into the dispersing tank, stir and disperse evenly; the condition is 1°C room temperature Stir for 1 hour at a speed of 1200 rpm. When finished, filter through a 420-mesh filter for later use. The above quantities total 100 servings. The strippable transfer black dye paste can be prepared.

Embodiment 3

[0027] First, 15 parts of water-based dyes are used for emulsion dyeing of 25 parts of silicone acrylic emulsion and 10 parts of EVA emulsion; the condition is 1 to 40 ° C at room temperature and stirring for 1 to 2 hours at a speed of 800 to 1200 rpm

[0028] After the above steps are completed, add 30.9 parts of water, 10 parts of alcohol ester 12, 6 parts of color-fixing agent, 3 parts of water-based penetrating agent, and 0.1 part of water-based defoamer into the dispersing tank to fully stir and disperse evenly; the condition is 1 to 40 Stir at room temperature for 0.5 to 1 hour at 800 rpm. When finished, filter through a 250 to 420 mesh filter for later use. The above quantities total 100 servings. The strippable transfer black dye paste can be prepared.

[0029] In the above examples, the black water-based dye can be selected from Wenzhou Meiernuo Chemical Co., Ltd. metal complex dye water-oil amphoteric color essence, the silicon-acrylic emulsion can be selected from...

Abstract

The invention discloses water soluble strippable dye transfer color paste, which is prepared by the following raw materials: 25-35% of silicone / acrylic emulsion, 15-19% of water-based dye, 20-35% of water, 1-5% of alcohol ester 12, 10-15% of EVA emulsion, 3-6% of color fixing agent, 1-3% of water-based penetrant and 0.1-1% of water-based defoamer. The preparation method is implemented as follows: performing emulsion dying on the silicone / acrylic emulsion and the EVA emulsion by the water-based dye under the condition of stirring for 1-2h at the room temperature of 1-40 DEG C and the revolving speed of 800-1200 turns / min; pouring the water, the alcohol ester 12, the color fixing agent, the water-based penetrate and the water-based defoamer in a dispersion kettle, fully stirring and evenly dispersing; and filtering by a 250-420-meshed sieve for standby use to obtain the water soluble strippable dye transfer color paste. The water soluble strippable dye transfer color paste can be diluted by tap water in the printing application process, and the tap water can be directly used for cleaning the printing without any harm on environment and human body.

Description

technical field [0001] The invention relates to a water-soluble peelable transfer dye color paste and a preparation method of the dye color paste. Background technique [0002] In recent years, the use of thermal transfer printing in export products, environmental protection products, etc. has been restricted by restrictions due to environmental protection factors. The heat transfer printing that has been updated accordingly has introduced the old and brings forth the new, and it is rushing to the market in terms of environmentally friendly plastic products. The heat transfer printing of these products has been inseparable from people's lives. With the improvement of environmental protection requirements, the country also has relevant environmental protection laws for new product materials and thermal transfer dye pastes to control the release of volatile organic compounds. At present, thermal transfer printing is still in the initial stage of development in my country, and...
