Problems solved by technology

[0002] At present, the use of sodium alginate as a printing paste is an ideal paste, but sodium alginate resources are relatively scarce, the cost is high, and the stability period is short. It can only be stored for 2 days, so the stability of the printed paste is not high, and the dosage is also expensive.

Embodiment 1

[0010] A printing paste of this embodiment and its preparation method, including the following components by weight ratio: carboxymethyl starch solution: sodium alginate: mineral oil = (1:35:35)—(1:40:40) ; Wherein the carboxymethyl starch solution is composed of the following raw materials in parts by weight: corn starch: chloroacetic acid: sodium hydroxide=1:1.5:3. The printing paste and its preparation method include the following steps: 1) according to the above weight ratio, first dissolve cornstarch in denatured alcohol and disperse fully; then add sodium hydroxide, control the pH to 9, and heat React for 45 minutes at low temperature, add chloroacetic acid solution, then add sodium hydroxide to control the pH of the reaction solution to be greater than 10; then use glacial acetic acid to neutralize to neutral, add sodium alginate powder, filter and spray mineral oil at the same time, continue Stir for 1 hour to obtain the finished printing paste. This embodiment has go...

Abstract

The invention discloses a printing thickner and a preparation method thereof. The printing thickner comprises the components by weight percent as follows: carboxymethyl starch solution, sodium alga acid and mineral oil, wherein the ratio of the carboxymethyl starch solution to the sodium alga acid to the mineral oil is equal to (1:35:35)-(1:40:40), the carboxymethyl starch solution comprises raw materials by weight part as follows: corn starch, chloroacetic acid and sodium hydroxide, wherein the ratio of the corn starch to the chloroacetic acid to the sodium hydroxide is equal to 1:1.5:3. The printing thickner has good stability, is convenient to store, is good in applicability and is suitable for various fibers; and through the adoption of the preparation method, the using amount of the thickner is saved, the production cost is reduced, and the preparation method is simple.

Description

technical field [0001] The invention relates to a printing paste and a preparation method thereof. Background technique [0002] At present, the use of sodium alginate as a printing paste is an ideal paste, but sodium alginate resources are relatively scarce, the cost is high, and the stability period is short. It can only be stored for 2 days at room temperature, so the printed paste is stable. The safety is not high, and the dosage is also expensive. Contents of the invention [0003] The purpose of the present invention is to provide a printing paste and its preparation method. The present invention has good stability, convenient storage, good applicability, suitable for various fibers, less paste consumption, lower production cost, and simple preparation method. [0004] In order to achieve the above object, technical scheme of the present invention is: [0005] A printing paste and a preparation method thereof, comprising components in the following weight ratio: c...
