Description
Technical field
The invention belongs to technical field of fine, be specifically related to one and be applicable to tobacco bale aqueous intaglio printing, light water
Property intaglio printing, water silk screen painting, aqueous flexible plate printing, aqueous inner wall paint, the water-based metal pigment of water-borne wood coating
Granule and production technology thereof.
Background technology
In the past in order to obtain the effect possessing metal aesthetic feeling, technique technician generally uses solvent borne metal pigment particle or molten
Agent metallic pigments powder is equipped with the VOC(VOC Volatile Organic such as esters, benzene class, ketone
Compounds) solvent is in harmonious proportion pulping, then be blended into the coating lacquer of ester dissolubility or ester soluble printing varnish formed metallic paint or
Metallic ink, is used for spraying and printing.
Nowadays in the field of fine chemical of coating or ink, in order to economize on resources and reduce public hazards, water paint and aqueous
The amount using organic solvent in ink gradually decreases.At present, only inorganic solvent water and organic solvent ethanol are considered at energy
Enough meet the normal needs used and environmental pollution will not be produced.
The surface of water-based metal pigment processes the surface being different from solvent borne metallic pigments and processes, and water-based metal pigment can
To keep form and aspect, brightness, gloss, metal sense, dispersibility constant under water environment for a long time, and solvent borne metallic pigments are in
Water environment will be aoxidized for most 24 hours by aqueous systems, loses original form and aspect, brightness, metal sense and produces coagulation and then report
Useless, in order to preferably mate aqueous environments, in actual applications, water-based metal pigment substitutes solvent borne metallic pigments to be become newly
Trend, the demand of water-based metal pigment is the most increasing.The form of water-based metal pigment is mainly powder and slurry at present, but
Following drawback is there is in water-based metal pigment powder and water-based metal pigment slurry in production application:
Water-based metal pigment powder, such as: Shu Lunke aqueous copper bronze 4350 Pale Gold(Germany), diamond aqueous copper bronze
S1770(China), like card aqueous copper bronze ROTOFLEX XA 8-203 Pale Gold(Germany), the new prosperous aqueous aluminum argentum powder that navigates
XH908(China), pearl receive youngster pearl essence SCI496(China) etc. come under fine particle (ParticulateMatter2 ~ 25 μ
M), the formation in atmosphere that can suspend the long period is similar to the air pollution system of PM2.5.This air pollution system may result in as follows
Adverse consequences: 1. produce environmental pollution.2. infringement inspirator's lung health.3. cause Mechanical System Trouble.4. cause circuit event
Barrier.5. powder volume is big, and in transport, to store link the most inconvenient, implicit environmental risk.
Water-based metal pigment slurry, such as: Shu Lunke water aluminum-silver slurry NPW-1700(Germany), like card aqueous copper gold paste ZG-
0208_1 Rich Gold(Germany), rising sun sun water aluminum-silver slurry P-9115S(China) etc. be all water-based metal pigment powder with water,
The auxiliary agents such as ethanol, n-butyl alcohol, propylene glycol monomethyl ether equal solvent and dispersant, coupling agent, preservative are adequately mixed having of formation
The slurry of certain fluid ability.Its drawback existed is: 1. have risk of leakage when slurry packages in damaged condition, deformation.2. organic solvent
Addition be generally 15% ~ 48%, have inflammable risk.3. the slurry longer-term storage containing aluminium element can produce gas, even flatulence
Blast.4. longer-term storage occurs oxidation to lose the metal sense of water-based metal pigment, gloss, the dispersion of reduction water-based metal pigment
Property causes scrapping.
Only have Germany the most in the world and like that card can provide strip water metallic pigments commodity, such as: ROTOSAFE Aqua 260
003 aluminum Rhizoma Humatae Tyermanni (pigment content 95%), (pigment contains ROTOSAFE Aqua ND 220 601 Rich Gold green grass or young crops oroide gold bar
Amount 90%), ROTOSAFE Aqua ND 220 603 Pale Gold red oroide gold bar (pigment content 90%).But it all exists
The defect that selling at exorbitant prices, pigment content are relatively low.And the non-pigment part wherein filled, for resin portion, and the depositing in a large number of resin
Certain coupling risk will brought for the subsequent applications of these strip water metallic pigments.
Summary of the invention
The purpose of the present invention is exactly the defect overcoming above-mentioned prior art to exist and provides a kind of safety and environmental protection, is prone to add
Work, stable in properties, high pigment content, economical and practical water-based metal granules of pigments and production technology thereof.The aqueous of the present invention

(3) cream processed: in the stirred opening cylinder of a constant volume, is initially charged water-based metal pigment powder or slurry, adds liquid afterwards
Phase component, after addition, stirring is in harmonious proportion to homogeneous paste；
(4) molding: mastic is put into hydraulic press extrusion die, with 60 ~ 100 standard atmospheric pressures, diameter 0.4 ~ 2.5mm mould mouth
Footpath is pressed into strip；
(5) it is dried: room temperature blower fan dries up, and makes strip mastic slowly be dried to strip solid；
(6) strip solid aridity inspection: taking 100g strip solid and be placed in thermostatic drying chamber and be dried, drying condition is 45
DEG C, 24h, be dried after weigh, if weight loss≤0.5%, then judge degree of drying qualified, can be packaged；If weight is damaged
Lose ＞ 0.5%, if needing to continue to be dried；
(7) encapsulation: accurately weigh quantitative water-based metal granules of pigments in plastic bag by packed weight, by plastic bag tying also
Load in metal bucket, cover bung and seal, labelled i.e. obtain water-based metal granules of pigments finished product.
