Description
Technical field
The present invention relates to a kind of mill base production technical field, specifically a kind of bi-component ash mill base and production work thereof
Skill.
Background technology
Mill base is a kind of water miscible coating, is widely applied to now in the life of people, in the method producing mill base,
Each plant formula is different, and the product produced is very different, but the mill base produced of prior art generally also exist with
Lower Railway Project: 1. in preparation process, the speed that raw material becomes jelly is relatively slow, affects production efficiency；2. after coating film forming,
Impact resistance is poor；3. coating color sensation is bad, and coloring effect is undesirable in process of production；4. when producing, water solubility problems
Can cause in mill base containing impurity such as little granules.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of bi-component ash mill base and production technology thereof, in order to solve
Certainly above technical problem.
The present invention solves the technical scheme that its technical problem taked and includes: a kind of bi-component ash mill base, the group of this mill base
Divide and the content of each component be:
Mill base resin 178～182 weight portion；
Dispersion resin 18.90～19.30 weight portion, can increase the dispersion of filler so that it is mixing is faster, it is easier to formed
Jelly；

Butyl glycol ether 228～232 weight portion, this solvent solubility is best, can strengthen water solublity and levelling effect；
Propylene glycol monomethyl ether 18.40～18.80 weight portion, can strengthen the thickness of paint film, and the thickest antiseptic effect of paint film is the best, adds
The paint film making the thickness of 10 microns originally after entering propylene glycol monomethyl ether increases to 20～50 microns；
Carboxylic acid 13～17 weight portion.
Described titanium dioxide is rutile titanium white lead, instead of original anatase thpe white powder, which enhances mill base
Quality, makes paint film finer and smoother, enhances impact resistance.
Described inserts is china clay, and china clay also has the effect of the impact resistance strengthening paint film.
Described carbon black is high-carbon black pigment.
Described high-carbon black pigment model is 1060 carbon blacks, and common pigments carbon black should not be dissolved in water, and high-carbon black pigment has
Higher hydrophilic, and consumption is few, and coloring effect is more preferable, and when being dissolved in paint, pigment will not swim in surface.
Described carboxylic acid is formic acid, instead of original lactic acid or glacial acetic acid, formic acid good water solubility, and dispersibility is strong, it is possible to
Avoid that latting drown occurs little granule.
A kind of bi-component ash mill base production technology, comprises the following steps:
Step one, checks that sand mill is the cleanest, and whether each valve puts in place；
Step 2, by mill base resin, dispersion resin, titanium dioxide, china clay, 1060 carbon blacks, isopropanol, butyl glycol ether, third
Glycol methyl ether is added sequentially to draw in tank, then stirs；
Step 3, adds grinding bead, grinds with sand mill, and wherein grinding bead needs screen once half a year, it is therefore an objective to will be thin
Little is ground rejecting, maintains grinding effect；
Step 4, meter weight, filters discharging, is driven in finished product still and stirs 25～35 minutes, carry out matter after having stirred
Amount detection；
Step 5, carries out tune and converts after having detected, adjust and product carries out after having converted final sampling detection, finally carry out
Filter and package.
In described step 2, the content of each component is respectively as follows: mill base resin 178～182 weight portion, dispersion resin
18.90～19.30 weight portions, rutile titanium white lead 417.30～417.70 weight portion, inserts 44～48 weight portion, 1060 carbon
Black 2.5～3.5 weight portions, isopropanol 68～72 weight portion, butyl glycol ether 228～232 weight portion, propylene glycol monomethyl ether 18.40
～18.80 weight portions；The mode of stirring is: the rotating speed of at least 2000 revs/min stirs 0.5～1 hour, then stands 1.5～2.5
Hour.
In described step 3, raw mill to fineness less than or equal to 15 microns, is needed to lead in process of lapping by grinder
Enter to cool down water, prevent temperature from crossing high solvent volatilization loss material, need after having ground to carry out fineness test with Hegman grind gage.
In described step 5, add the formic acid of 13～17 weight portions when adjusting and converting and according to the testing result in step 4
Add distilled water diluting, then stirring 25～35 minutes, wherein, the amount not specially provided for of distilled water, mainly according to different clients
Technology require come adjusting coating sliminess.
The invention has the beneficial effects as follows: the mill base produced with this process has stronger hydrophilic, coloring effect
More preferably, after using, the paint film thickness of formation, has preferable impact resistance and corrosion resistance to fruit, and production technology is simple, conservation.
