Abstract

The present invention relates to printing ink essence and a preparation method thereof. The ink essence is composed of rice flour or wheat flour, corn powder, starch, pigments, bentonite or talcum powder as an auxiliary agent, calcium carbonate, borax or sodium propionate, calcium propionate, sodium benzoate or sodium ortho-phenylphenate, sodium hydroxide (potassium hydroxide) and sodium nitrate (calcium nitrate). The preparation method comprises: the rice flour, etc., are mixed and ground with the pigments, the bentonite or the talcum powder, the calcium carbonate powder, the borax or the sodium propionate, the calcium propionate, the sodium benzoate or the sodium ortho-phenylphenate; the obtained materials are packaged according to amount; the sodium hydroxide (potassium hydroxide) and the sodium nitrate (calcium nitrate) are subpackaged according to amount and are packaged; thereby, the printing ink essence is obtained. The ink essence is suitable for screen printing on corrugated paper boxes, paper bags, slogan advertisements, packaging cloth, etc. The printing ink essence has the advantages of strong colouring force, and abrasion resistance, light fastness and water resistance of printed materials.

Description

Printing ink-essence and preparation method thereof

The present invention relates to print the black class of usefulness, particularly powdery China ink of using of silk screen printing and preparation method thereof.

Silk screen printing at present is starchiness with China ink, and storage period is short, produces dangerously, and printing performance is poor, do solid slow, easily sticking the connection.

The objective of the invention is to overcome the shortcoming of pasty state China ink, a kind of solid, powdery China ink (printing ink-essence) and preparation method thereof is provided, this black finishing impression brush performance is good, and easily dried, wear-resisting, sun-proof, water-fast does not glue connection, and cost is low.

The technical scheme that realizes the object of the invention is based on rice meal or starch, is equipped with colorant and auxiliary agent, is refined into the screen printed inks essence by allocation processing.

Concrete measure is based on rice meal or flour, Semen Maydis powder, sweet potato starch, potato starch, is equipped with homemade commercially available colorant and is pigment or dyestuff and auxiliary agent and make through mixing vibration or grinding.

Colorant such as carbon black, ultramarine (Na ₆Al ₄Si ₆S ₄O ₂₀Or Na ₂Al ₆S ₂O ₂₄Produce Tianjin), red iron oxide, iron oxide yellow, chrome yellow Cbrome yellow, titanium dioxide powder, (molecular weight 79.88), zinc oxide, bronze red C bronze red C (Lake red C, the bright red LC of rubber)
