Abstract
The invention relates to an environment-friendly brown vat dye and a commercial production method thereof. The method is specifically characterized by beating 30% of C.I. vat brown 1 filter cakes, 1-5% of dispersing agent 610, 1-5% of dispersing agent 615, 25-35% of dispersing agent MF, 3-7% of dispersing agent 83A, 15-25% of dispersing agent DN14 and 6-10% of dispersing agent 85A by weight, carrying out grinding by wet grinding, sending the powder to a spray dryer to be dried via a pipe after grinding for 50h, simultaneously spraying 0-2% of dust laying oil and finally packaging the finished product. The environment-friendly brown vat dye has the following beneficial effects: the diffusivity of the vat dye reaches 4-5 grades; the dispersing stability of the suspensoid is over 99%; the dust float property reaches 4-5 grades; the large particles reach the top grade; the limits of 23 harmful aromatic amines and 10 heavy metals conform to the national standard requirements; the pad dyeing rate of the suspensoid is improved by over 10%; all above completely meets the requirements of the environment-friendly dye series products; at the same time, the product is convenient to use and can be used by direct beating without grinding.
Description
Technical field
The present invention relates to a kind of vat dyes and commercialization manufacture method thereof, particularly a kind of environment-friendly type brown vat dye (Vat Brown L-BR) and commercialization manufacture method thereof.
Background technology
Vat dyes is the high-grade dyestuff that a veriety is numerous, bright in colour, fastness is excellent, because vat dyes has good sun-proof, weather, heat-resisting, anti-solvent, washing fastness, can be widely used in the printing and dyeing of cotton, hair, silk, fiber crops, synthon and BLENDED FABRIC thereof, intertexture, be cotton with a kind of high-grade products in dyestuff.
because vat dyes does not contain the azoic dyestuff that cracking under given conditions produces 23 kinds of carcinogenic aromatic amines, it not irritative dye, carinogenicity dyestuff and acute toxicity dyestuff, do not contain environmental hormone, and the colourity of waste water is low when using, it is a kind of substitute of forbidding dyestuff, but require to analyze from environment and ecological protection, the vat dyes manufacturing step is many, building-up reactions is complicated, sometimes also use the Organohalogen compounds such as polystream to make solvent and heavy metal and derivatives as catalyst thereof, this just causes using the heavy metals in process content overproof of vat dyes, do not meet environmental requirement, and, in the commercialization manufacturing processed of vat dyes, due to auxiliary agent and proportioning thereof select improper, also can cause product pad dyeing dye uptake low, the generation of the problems such as the dispersion stabilization of suspensoid and diffustivity are poor, therefore vat dyes is many problems of being concerned about to environment and ecological pollution always.
In recent years, along with market development, low metal Ecological vat dyestuffs becomes market to be expected, original handicraft product can't satisfy social desirability, therefore, comes the satisfying the market needs in the urgent need to a kind of low metal environmentally friendly machine.
Summary of the invention
It is good that the technical problem to be solved in the present invention is to provide diffustivity in a kind of water, suspensoid dispersion stabilization and dust from flying rank, the superior level of macrobead, 23 kinds of harmful aromatic amines are limited the quantity of to limit the quantity of with 10 heavy metal species and are all complied with the national standard requirements, and the pigment pad dyeing dye uptake improves environment-friendly type brown vat dye and the commercialization manufacture method thereof more than 10%.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of environment-friendly type brown vat dye is characterized in that this dyestuff is composed of the following components: C.I. Vat brown 1, dispersion agent 610, dispersion agent 615, Dispersant MF, dispersion agent 83A dispersion agent DN14, dispersion agent 85A and dust laying oil.
As limitation of the invention further, in dyestuff of the present invention, the weight fraction of each material is respectively: the dispersion agent 85A of dispersion agent DN14, the 6-10% of dispersion agent 83A, the 15-25% of dispersion agent 85A, the 5-15% of the dispersion agent 615 of 30% C.I. Vat brown 1, the dispersion agent 610 of 1-5%, 1-5%, the Dispersant MF of 25-35%, 5-15% and the dust laying oil of 0-2%.
The commercialization manufacture method of the olive colour vat dyes of a kind of environment-friendly type of the present invention is to be the dispersion agent making beating of 30% C.I. Vat brown 1 and certain proportioning with weight fraction, adopt the broken technology of wet-milling to pulverize grinding, grind and send to the spray-drying tower drying by pipeline after 30 hours, simultaneously can spray into dust laying oil, the end product packing, the waste gas that produces in spraying drying passes through dust removal by filtration by cyclone dust collector.
Can buy on the raw materials market that the present invention adopts.Wherein the C.I. Vat brown 1, can select the environment-friendly type Vat Brown BR of Jiangsu Yabang Dyestuffs Co., Ltd.'s production.
C.I. (Color Index) is international Colour index number.
After adopting technique scheme, the beneficial effect that the present invention obtains is: test by correlated performance, vat dyes diffustivity of the present invention reaches the 4-5 level, the suspensoid dispersion stabilization reaches more than 99%, dust from flying reaches the 4-5 level, the superior level of macrobead, 23 kinds of harmful aromatic amines are limited the quantity of to limit the quantity of with 10 heavy metal species and are all complied with the national standard requirements, the pigment pad dyeing dye uptake improves more than 10%, satisfy environmental protection series dye product requirement fully, simultaneously, this product sand milling that need not easy to use, directly making beating can be used.
