Embodiment 1

[0030] This embodiment includes the following steps:

[0031] 1) Preparation of ZnO nano thorn ball particles;

[0032] Under the condition that the temperature of the deionized water is raised to 30°C, high-purity argon gas with a purity of 99.95% is passed into the deionized water for 0.5 h, and after the oxygen in the pure water is removed, an inorganic zinc salt is added, And keep stirring, set the stirring speed to 800rpm, and the stirring time to 0.2h, then add the dispersant, stir for 0.2h to make the solution mix evenly, and obtain the mixed liquid A;

[0033] Add inorganic additives to the mixed solution A, adjust the pH value to 8, continue to stir for 0.3h, and pass argon into the mixed solution A, heat the mixed solution A, and evaporate the mixed solution A After moisture, reflux and cool down to room temperature to obtain solution B containing ZnO nano thorn ball particles, wherein the heating rate is set to 6-8°C / min, and the cooling rate is set to 5-8°C / min. ...

Embodiment 2

[0039] This embodiment includes the following steps:

[0040] 1) Preparation of ZnO nano thorn ball particles;

[0041] Under the condition that the temperature of the deionized water is raised to 50°C, high-purity argon gas with a purity of 99.95% is introduced into the deionized water for 1 hour, after the oxygen in the pure water is removed, an inorganic zinc salt is added, and Stir continuously, set the stirring speed to 1000rpm, and the stirring time to 0.2h, then add the dispersant, stir for 0.2h to make the solution mix evenly, and obtain the mixed solution A;

[0042] Add inorganic additives to the mixed solution A, adjust the pH value to 8.5, continue stirring for 0.4h, and pass argon gas into the mixed solution A, heat the mixed solution A, and evaporate the mixed solution A After moisture, reflux and cool down to room temperature to obtain solution B containing ZnO nano thorn ball particles, wherein the heating rate is set to 6-8°C / min, and the cooling rate is set ...

Embodiment 3

[0048] This embodiment includes the following steps:

[0049] 1) Preparation of ZnO nano thorn ball particles;

[0050] Under the condition that the temperature of the deionized water is raised to 70°C, high-purity argon gas with a purity of 99.95% is introduced into the deionized water for 1 hour. After the oxygen in the pure water is removed, an inorganic zinc salt is added, and Stir continuously, set the stirring speed to 1500rpm, and the stirring time to 0.2h, then add the dispersant, stir for 0.2h to make the solution mix evenly, and obtain the mixed solution A;

[0051] Add inorganic additives to the mixed solution A, adjust the pH value to 9, continue to stir for 0.5h, and pass argon into the mixed solution A, heat the mixed solution A, and evaporate the mixed solution A After moisture, reflux and cool down to room temperature to obtain solution B containing ZnO nano thorn ball particles, wherein the heating rate is set to 6-8°C / min, and the cooling rate is set to 5-8°...

Abstract

The invention discloses an auxiliary capable of improving printing performance of a composite ivory board and a preparation method thereof. The auxiliary is prepared from, by weight, 10-20 parts of inorganic zinc salt, 10-20 parts of inorganic additive, 0.5-1 part of surfactant, 0.5-1 part of dispersant and 60-80 parts of deionized water. ZnO nano acanthosphere particles after surface modification are adopted as the auxiliary in the process of printing the composite ivory board; the ZnO nano acanthosphere particles have siphon microstructure, and an active agent is adopted for chemical surface modification, so that ink absorptivity of the composite ivory board can be further improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an additive for improving the printing ink absorption of composite white cardboard and a preparation method thereof. Background technique [0002] Paper is one of the indispensable and important supplies for human study, work and life. Traditional papermaking has caused great damage to the ecological environment due to excessive felling of trees and the three wastes produced in the traditional papermaking industry. The demand for environmental protection in raw materials and paper product processing is getting higher and higher. Composite white cardboard, that is, stone paper, is a new material between paper and plastic, which can replace some traditional functional paper, professional paper, and most of the traditional plastic packaging. And it has the characteristics of low cost and controllable degradation, which can save users a lot of cost and will not cause pollution. ...
