Embodiment 1

[0014] The safe and environment-friendly printing paste involved in this embodiment, the weight components of each raw material are 20 parts of sodium alginate, 10 parts of konjac flour, 30 parts of carboxymethyl cellulose, 5 parts of sodium hexametaphosphate, 0.5 part of citric acid, peach 10 parts of glue, 100 parts of deionized water.

[0015] The preparation method of the safe and environment-friendly printing paste involved in this embodiment, its specific process steps are as follows:

[0016] (1) Preparation of peach glue: choose peach trees with a tree age of more than 3 years, and harvest peach glue in summer. The viscosity of peach glue at this time is relatively high. Cut at a height, or cut from a branch of a peach tree, light yellow transparent viscous liquid flows out continuously from the cut, collect it with a storage container, add an ethanol solution with a concentration of 40% by volume, stir, filter, and remove impurities. Get the peach gum solution for la...

Embodiment 2

[0023] The safe and environment-friendly printing paste involved in this embodiment, the weight components of each raw material are 25 parts of sodium alginate, 15 parts of konjac flour, 40 parts of carboxymethyl cellulose, 10 parts of sodium hexametaphosphate, 0.8 part of citric acid, peach 13 parts of glue, 110 parts of deionized water.

[0024] The preparation method of the safe and environment-friendly printing paste involved in this embodiment, its specific process steps are as follows:

[0025] (1) Preparation of peach glue: select peach trees with a tree age of 5 years, and harvest peach glue in summer. The viscosity of peach glue at this time is relatively high. The specific harvesting method is: from the height of 1.2-1.8 meters of peach trees Carry out cutting, or cut from the branch of the peach tree, light yellow transparent viscous liquid continuously flows out from the cut, collect it with a storage container, add an ethanol solution with a volume percentage conc...

Embodiment 3

[0032] The safe and environment-friendly printing paste involved in this embodiment, the weight components of each raw material are 30 parts of sodium alginate, 20 parts of konjac flour, 50 parts of carboxymethyl cellulose, 15 parts of sodium hexametaphosphate, 1 part of citric acid, peach 15 parts of glue, 120 parts of deionized water.

[0033] The preparation method of the safe and environment-friendly printing paste involved in this embodiment, its specific process steps are as follows:

[0034] (1) Preparation of peach glue: select peach trees with a tree age of 7 years, and harvest peach glue in summer. The viscosity of peach glue at this time is relatively high. The specific harvesting method is: from the height of 1.2-1.8 meters of peach trees Carry out cutting, or cut from the branch of the peach tree, light yellow transparent viscous liquid continuously flows out from the cut, collect it with a storage container, add an ethanol solution with a volume percentage concen...

Abstract

The invention belongs to the technical field of the printing and dyeing chemical industry and relates to safe and environmentally friendly printing paste and a preparation method thereof. The safe andenvironmentally friendly printing paste comprises sodium alginate, konjac powder, carboxymethyl cellulose, sodium hexametaphosphate, citric acid, peach gum solution and deionized water. The preparation method comprises peach gum liquid preparation, mixed solution A preparation, mixed solution B preparation, sodium hexametaphosphate thickener preparation and finished product preparation. Natural plant glue-peach gum solution, carboxymethylcellulose and citric acid are processed into the mixed solution A, sodium alginate and konjac powder are processed into the mixed solution B, solids are separated, the mixed solution B and sodium hexametaphosphate are emulsified into a sodium hexametaphosphate thickener, and the sodium hexametaphosphate thickener, the crushed solids and the mixed solutionA are mixed and uniformly stirred to form the printing paste. Through use of the peach gum solution and synergism of the components, the printing and dyeing patterns have clear outlines, bright colors, a high dye yield, good stability and easy storage.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing chemicals, and relates to a safe and environment-friendly printing paste and a preparation method thereof. Background technique [0002] Printing paste refers to a polymer compound that can thicken the printing paste. In the printing process, the printing paste mainly plays four roles: as a thickener for the printing paste to make it have a certain viscosity; as a dispersion medium for dyes, chemicals, auxiliaries and solvents in the printing paste; Diluent; as a delivery agent for dyes, as a carrier; as an adhesive. As an important component of printing paste, printing paste determines the running performance of printing, the amount of color given to the surface of the dye, the clarity, smoothness, and feel of the pattern outline. With the continuous development of printing technology, the requirements for printing paste are getting higher and higher. There are more and more types ...
