Abstract

An EVA printing ink is composed of resin liquids, dispersing agents, coloration pigments and fillings. The resin liquids are composed of EVA emulsion, n-butyl acetate, acetone, chloroform, ethanol and dimethylbenzene, the dispersing agents utilize triethanolamine, the coloration pigments respectively utilize pigment red, pigment yellow, pigment blue, carbon black and titanium dioxide, and the fillings utilize light calcium carbonate. The n-butyl acetate, the acetone, the chloroform, the ethanol and the dimethylbenzene with formula quantities are put into a mixing tank to be mixed into a mixed solvent, the EVA emulsion is added with stirring, the solvent is dissolved into a sticky resin liquid, and one of the coloration pigments and the light calcium carbonate with formula quantities are melted into the resin liquid, dispersing agents are added, the mixture is stirred fully, then the technical required fineness is a monochrome EVA printing.

Description

EVA printing ink

Technical field

The present invention relates to a kind of EVA printing ink, specifically refer to be used for the printing of EVA goods, cover with paint, lacquer, colour wash, etc. the colour developing raw material that adds man-hour, belong to the painting technical field.

Background technology

The EVA resin has been widely applied to the every aspect of people's life.Yet when the FVA goods are implemented printing, covering with paint, or the special-purpose EVA ink special of use import, or use the printing ink of other resin types to substitute.Use the special-purpose EVA printing ink of import to cost an arm and a leg, increase worker's cost on foot, use other resin type printing ink to substitute, performances such as amalgamation, stretch-proof are all not good enough, influence quality product.

Summary of the invention

The present invention discloses a kind of EVA resin ink special, to replace expensive imported product.

The technical scheme that the present invention adopts is: printing ink is by resin liquid, dispersion agent, colour developing pigment, stopping composition four big components formations.With the EVA emulsion is structural resin; YLENE, N-BUTYL ACETATE are main solvent; Acetone, chloroform, ethanol are secondary solvent, are configured to the resin liquid component in proportion, and dispersion agent adopts trolamine; Colour developing pigment adopts Pigment red, Pigment Yellow 73, Pigment blue, carbon black, white titanium pigment, and stopping composition adopts light calcium carbonate.

At first N-BUTYL ACETATE, acetone, chloroform, ethanol, the YLENE with formula ratio places agitation vat to be mixed into mixed solvent; Under condition of stirring, add the EVA emulsion; Be dissolved into thick resin liquid, a kind of, the light calcium carbonate with the colour developing pigment of formula ratio is blended in resin liquid again, and the back adds dispersion agent; After fully stirring, the technical requirements fineness is monochromatic EVA printing ink.

The invention has the beneficial effects as follows: substitute expensive imported product, improve the quality product of low-and-medium-grade products printing, covering with paint.

Embodiment:

By weight percentage, EVA emulsion 41%, N-BUTYL ACETATE 16%, acetone 13%, chloroform 10%, ethanol 0.1%, YLENE 20%.After at first the chloroform of formula ratio and butanols being dissolved each other; Join the N-BUTYL ACETATE, acetone, the YLENE mixed solvent that place agitation vat again; Open stirrer; Under condition of stirring, slowly add the FVA emulsion, become viscous liquid, be resin liquid and deposit subsequent use when the FVA emulsion thoroughly is dissolved in solvent.

Resin liquid 64%, white titanium pigment 18%, light calcium carbonate 17%, trolamine 1%.At first the resin liquid with formula ratio places agitation vat, starts stirrer, under condition of stirring; Add light calcium carbonate again after adding white titanium pigment; Add trolamines Deng the whole moistening backs of solid powder, the restir grinding that promptly is available on the machine half a hour approximately, fineness reach 3 ~ 5 μ m the white ink finished product;

Resin liquid 69%, carbon black 13%, light calcium carbonate 17%, trolamine 1% is processed into the black ink finished product with method;

Resin liquid 69%, pigment orchid 8%, light calcium carbonate 22%, trolamine 1% is processed into the blue ink finished product with method;

The adding Pigment red is a red ink, and the adding Pigment Yellow 73 is a Yellow ink, and prescription is with together blue.

After last machine is ground to the fineness value of requirement, i.e. tinning, vanning are finished product.
