Embodiment 1

[0025] In this example, the new high-gloss environmentally friendly paper dye is made of the following percentages of raw materials: 15% modified starch, 12% nano-titanium dioxide, 8% polyvinyl alcohol resin, 10% pearlescent pigment, and 3% carboxymethyl cellulose , xanthan gum 3%, thickener 1%, defoamer 1%, the balance is deionized water;

[0026] Among them, the modification method of the modified starch is as follows: weigh the starch, add deionized water to prepare a starch solution with a mass fraction of 20%, put it in a probe-type ultrasonic instrument for 10 minutes, filter it with suction, and place the filtered product at a constant temperature of 35°C. Dried in a blast drying oven, after the drying was complete, ground to obtain modified starch, wherein the temperature of the ultrasonic instrument was 40°C, and the starch was potato starch;

[0027] The average particle size of nano-titanium dioxide is 20nm; the defoamer is tributyl phosphate; the thickener is hydro...

Embodiment 2

[0034] In this example, the dyes for new high-gloss environmental protection paper are made of the following percentages of raw materials: 25% modified starch, 12% nano-titanium dioxide, 17% polyvinyl alcohol resin, 18% pearlescent pigment, and 7% carboxymethyl cellulose , xanthan gum 7%, thickener 2%, defoamer 2%, the balance is deionized water;

[0035] Among them, the modification method of the modified starch is as follows: weigh the starch, add deionized water to prepare a starch solution with a mass fraction of 25%, put it in a probe-type ultrasonic instrument for 15 minutes, filter it with suction, and place the filtered product at a constant temperature of 40°C. Dried in a blast drying oven, and after the drying was complete, ground to obtain modified starch, wherein the temperature of the ultrasonic instrument was 45°C, and the starch was cornstarch;

[0036] The average particle size of nano-titanium dioxide is 50nm; the defoamer is simethicone; the thickener is asso...

Embodiment 3

[0043] In this example, the new high-gloss environmentally friendly paper dye is made of the following percentages of raw materials: modified starch 20%, nano-titanium dioxide 17%, polyvinyl alcohol resin 13%, pearlescent pigment 14%, carboxymethyl cellulose 5% , xanthan gum 5%, thickener 1.5%, defoamer 1.5%, and the balance is deionized water;

[0044] Among them, the modification method of the modified starch is as follows: weigh the starch, add deionized water to prepare a starch solution with a mass fraction of 23%, put it in a probe-type ultrasonic instrument for 12 minutes, filter it with suction, and place the filtered product at a constant temperature of 38°C. Dried in a blast drying oven, and after the drying was complete, ground to obtain a modified starch, wherein the temperature of the ultrasonic instrument was 43°C, and the starch was sweet potato starch;

[0045] The average particle size of nano-titanium dioxide is 30nm; the defoamer is lauryl phenylacetate; the...

Abstract

The invention provides a novel high-gloss environmentally-friendly paper dye and a preparation method thereof, and relates to the technical field of paper dyes, wherein the novel high-gloss environmentally-friendly paper dye is prepared from the following raw materials: modified starch, nanometer titanium dioxide, a polyvinyl alcohol resin, a pearlescent pigment, carboxymethyl cellulose, xanthan gum, a thickener, an anti-foaming agent, and deionization water. According to the present invention, the novel high-gloss environmentally-friendly paper dye has characteristics of health, environmentalprotection, stable chemical property, safety, reliability, convenience and practicality, can be stably stored for a long time, does not contain formaldehyde and volatile organic substances, and is beneficial to human health; and with the application of the dye in paper surface printing, the paper surface is beautiful, smooth, delicate, good handfeeling, natural and straight, the dyed paper does not easily fade after being used for a certain time, and has good stability, and the paper further has advantages of good pearlescent effect, high gloss and good color fidelity.

Description

technical field [0001] The invention relates to the technical field of dyes for paper, and relates to a novel dye for high-gloss environment-friendly paper and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to aesthetics and taste, and the demand for high-end food and cosmetic packaging paper is increasing, which makes traditional packaging paper unable to meet people's needs, and the quality and color of paper are increasingly popular. valued, [0003] Dye is an engineered material that coats the surface of paper and forms a firmly adherent film. Papermaking dye is an important part of coating and processing packaging paper, and it is not easy to fall off and change color. Not only can it play a decorative effect, making the paper beautiful, but it can also protect the paper well, improve the printing suitability of the paper, and endow the paper with certain special functions such a...
