Abstract
The invention discloses a preparation method for high-light disperse red dye, which comprises the following steps: (1) sequentially adding ethylene glycol phenyl ether, polyethylene glycol and potassium hydroxide in a reaction kettle for stirring, heating and dehydrating, putting disperse red FB in the reaction kettle for heating reaction, after that, cooling and dropwise adding methanol, filtering at the room temperature after standing, washing and dipping by methanol, and filtering and washing by hot water to present the neutral property to obtain a filter cake; and (2) adding the filter cake obtained in the step (1), methylene double-methyl naphthalene sulfonate, lignin, surface active agent, glass beads and water in a sand mill for grinding, spraying and drying to obtain the high-light disperse red dye. The technical scheme disclosed by the invention has simple preparation technique, and realizes recycling of solvent generated in the technique process and low yield of waste liquor; the light firmness of the finally prepared high-light disperse red dye is high and is up to 4-5 grade to totally satisfy the use requirements of automobile textiles on the high-light dye.
Description
Technical field
The present invention relates to the dispersed dye preparation field, relate in particular to a kind of preparation method of high Exposure to Sunlight dispersive red dye.
Background technology
The fast development of automotive industry, textile for automobile present the characteristics of variation, personalization and fashion-orientation.Fabric accounts for more than 50% in the automobile interior material.Particularly medium-to-high grade car and passenger vehicle, weaving face fabric not only are used for seat-cover fabric, and are used for car roof, heel post, door plate, sun visor etc. and coat fabrics.The large multiplex polyester of automobile interior trim fabric and polypropylene fibre are made.Polypropylene fibre can only be painted in spinning process with the pigment that good light fastness is arranged, and trevira then adopts the dyeing of rear road.Can only tolerate with the polyester vehicle fabric of common disperse dyeing and to be no more than 4 ~ 6 periodicity of illuminations (pressing the DIN75202 standard), the illumination meeting of longer time has obviously fabric to fade, also have serious color and luster and change.Automobile can make the temperature of narrow space in the automobile raise because travelling for a long time and tanning by the sun, and especially in summer, when day and night temperature was larger, cold cycling can further cause fading of automobile-used furnishing fabric and degrade.
In the dispersed dye new variety, take azo and fear quinones as main, be all 1-amino-4-hydroxy-2-substituting group such as C.I Disperse Red 59,146 etc. and fear the quinone based compound.The requirement that such dyestuff can't satisfy high Exposure to Sunlight appears in the existing market.
Summary of the invention
Technical problem to be solved by this invention is: the preparation method that simple, the high Exposure to Sunlight dispersive red dye of a kind of technique is provided.
For solving the problems of the technologies described above the technical solution used in the present invention: a kind of preparation method of high Exposure to Sunlight dispersive red dye the steps include:
1) add successively ethylene glycol phenyl ether, polyoxyethylene glycol and potassium hydroxide in reactor, stirring is warming up to 130 ~ 145 ℃ and dewaters; Behind 1 ~ 1.5h, drop into again Disperse Red FB, be warming up to 140 ~ 145 ℃; In 140 ~ 145 ℃ of insulation reaction 4 ~ 5h; Then be cooled to 50 ± 2 ℃; 50 ± 2 ℃ of control temperature in the kettle drip methyl alcohol, leave standstill 8 ~ 10h; Suction filtration under the room temperature soaks with methanol wash again; Suction filtration, hot water wash are to the neutral filter cake that gets;
2) step 1) gained filter cake adding dispersing agent MF, xylogen, tensio-active agent, glass bead and water are put into sand mill and grind, spraying drying obtains high Exposure to Sunlight dispersive red dye.
The preparation method of described high Exposure to Sunlight dispersive red dye, its reaction equation is:
In the step 1), the mass ratio of described ethylene glycol phenyl ether, polyoxyethylene glycol, potassium hydroxide, Disperse Red FB is: 18 ~ 20:9 ~ 10:1:16 ~ 18.
Step 2) in, the mass ratio of filter cake and dispersing agent MF, xylogen, tensio-active agent is: 1:0.3 ~ 09:1.2 ~ 1.5:0.8 ~ 1.6.
Described tensio-active agent is selected from one or more in the following goods and materials: stearic acid, Sodium dodecylbenzene sulfonate, quaternary ammonium compound, Yelkin TTS, amino acid pattern, betaine type, glycerin fatty acid ester, lipid acid sorb are smooth, polysorbate.
The present invention has following advantage and effect: technical scheme disclosed by the invention, preparation technology is simple, the solvent recoverable that produces in the technological process, waste liquid output is few, the high Exposure to Sunlight dispersive red dye that finally prepares, light fastness is high, reaches the 4-5 level, satisfies textile for automobile fully to the service requirements of high Exposure to Sunlight dyestuff.
