SU730771A1 - Ink for tampoprinting onto textile material - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to the field of PB (playing industry, namely, ink for printing on textile material. Known ink for printing on textile material, containing 10-29% of a copolymer of vinyl chloride with vinylidene chloride, 2-20% by weight of a copolymer of methacrylic acid amide with butyl copolymer. methacrylic acid ester, 1-27 wt.% pigment, 0.5-5 wt.% filler — aerosil, 5-8 wt.% propylene carbonate and the rest is dialkyl phthalate. The ink drawback is a low optical density of the impression, which is 30%. In addition, danna kra thermal stability in a narrow temperature range (10-80 0. The purpose of the invention is to increase the optical density of the print, as well as to increase the thermal stability of the paint. This goal is achieved due to the fact that the paint based on a binder, a copolymer of methacrylate acid and butyl acid, is known Methacrylic ester, pigment, filler, propylene carbonate and dialkyl phthalate as a filler contains a mixture of aerosil modified with divalent copper ions to 0.2–1.2% with calcium carbonate, barium sulfate or talc and op1olnitelno - polymethyl fenileiloksanovuyu resin at the following component ratio, wt%: Copolymer of methacrylic acid amide with butylether methacrylic kisloty3-6 polymethylphenylsiloxane resin 14-27 10-40 Pigment Aerosil3-5 calcium carbonate, barium sulfate or talc 9-40.

The content in the paint composition of prpimethylphenylsnloxane resin, aerosil modified with copper ions to O, 2-1.2%, to barium sulfate or calcium carbonate or talc eliminates paint penetration on the reverse side of the printed material and provides an increase in optical density of prints, since on the one hand, copper, being a polyvalent metal, forms coordination compounds in which the ligands are phenyl groups of a polymethylphenylsiloxane resin, and the central atom is copper; on the other hand, barium sulphate or calcium carbonate or talc contribute to the thickening of the paint and prevent the binder from penetrating to the reverse side of the porous polymeric material. The presence of polymethylphenylsiloxane resin provides heat resistance paint.

Aerosil is modified from 0.2 to 1.2% (a decrease or increase in the degree of modification leads to the formation of an insufficient amount of coordination compounds or a significant increase in viscosity, respectively) by air) in a flask to 50 ml of a 0.1 M solution of copper chloride and four times excess of butylamine, 1 g of aerosil is added. The suspension is mechanically mixed for one hour, then the aerosil is separated and washed with a solvent on the Shitt filter until the metal of chlorins disappears and dried at 70-80 ° C for 2-3 hours. The percentage of copper is determined by trilonometric, destroying the metal containing aerosil, nitrogen acid. Aerosil samples are analyzed for nitrogen content by the Dumas method, and for chlorine content by the potentiometric method. Phthalocyanine pigments, azo pigments and white are used as pigments.

Dialkyl phthalates (dimethyl phthalate, dibutyl phthalate and dioctyl phthalate) and propylenecarbo-, nat will be used as solvents.

The method is illustrated by the following examples.

First, a 20% solution of a copolymer of methacrylic acid amide with butyl methyl ester of methacrylic acid is prepared in a mixture of dialkyl phthalate and propylene carbonate in a ratio of 2: 1 to a 60% solution of limethylphenylsiloxane resin in dicyl phthalate. Then, in appropriate amounts by weight, they are ground on a three-roll paint mill to a particle size of 15 μm. Get white kras

How It can be seen from the table, the use of the proposed paint helps to improve its thermal stability, as well as to increase the optical density of the print. DETAILED DESCRIPTION OF THE INVENTION Zo Paint a pad on textile material containing a binder, a copolymer of methacrylic acid amide with methacrylic acid butyl ester, pigment, filler, propylene carbonate and dialkyl phthalate, differs from the fact that, with a chain of increasing the optical density of the impression, also increase the thermal stability of the paint; as a filler it contains a mixture of aerosil modified to 0-2.2% by ions of divalent copper, with calcium carbonate, barium sulphate or that according to claim and extra imethylfesiloxane resin with the following retention of components, weight,%: Methacrylic acid amide copolymer with butyl methacrylic acid 3-6-6 Polymethylphenylsiloxane resin14-27 Pigment1-4O Aerosil3-5 Calcium carbonate, barium sulfate or 39% carbonate, barium sulfate, 100% Pigment1O-4O Aerosil3-5 calcium carbonate, barium sulfate, calcium sulfate and O-4O.
