Problems solved by technology

[0003] Although traditional titanium dioxide can improve the whiteness and opacity of paper, its adhesion and wear resistance are not high enough. However, due to the changing environment of paper, especially high-grade paper, the color will also change when it is exposed to moisture and heat. Larger changes are prone to discoloration or even fading. In addition, high-grade paper also has higher requirements for wear resistance and shaping. The existing wear resistance of paper modified by titanium dioxide cannot meet the needs of use.

Embodiment Construction

[0010] The following is a list of components and mass percentages of titanium dioxide used for papermaking in the embodiments of the present invention:

[0011] Table 1 Component and Content Table

[0012] Potassium sulfate 1-4 Phosphoric acid 0.1-0.45 Ferrous sulfate 0.5-1 Zinc sulfate 0.05-0.35 Aluminum sulfate 0.05-0.3 Metatitanic acid (as TiO 2 Count) 95-98 Embodiment one 1.39 0.1 0.5 0.05 0.05 98 Embodiment two 2.9 0.45 1 0.35 0.3 95 Embodiment three 4 0.1 0.5 0.2 0.2 95 Embodiment four 2.2 0.3 0.8 0.1 0.1 96.5 Embodiment five 1 0.2 0.7 0.3 0.3 97.5 Embodiment six 3 0.4 0.6 0.25 0.25 95.5 Embodiment seven 2.2 0.3 0.7 0.25 0.2 96.35

[0013] where TiO 2 According to the supply and demand of raw materials, it can also be replaced by metatitanic acid, and the amount of metatitanic acid depends on the amount of TiO 2 Just do the calculation.

Abstract

The invention relates to titanium dioxide, in particular to a formula of titanium dioxide for papermaking. The titanium dioxide consists of the following components in percentage by mass: 1 to 4 percent of potassium sulfate, 0.1 to 0.45 percent of phosphoric acid, 0.5 to 1 percent of ferrous, 0.05 to 0.35 percent of zinc sulfate, 0.05 to 0.3 percent of aluminum sulfate, and 95 to 98 percent of titanium dioxide. A test shows that the titanium dioxide for papermaking is high in adhesion degree, and strong in wear resistance and moulding performance.

Description

technical field [0001] The invention relates to a titanium dioxide, in particular to a formulation of the titanium dioxide for papermaking. Background technique [0002] Titanium dioxide has unique physical and chemical properties and excellent pigment performance. A certain amount of titanium dioxide can make the paper have good whiteness, luster, thin and smooth, and non-penetrating when printing, so it is widely used in the paper industry [0003] Although traditional titanium dioxide can improve the whiteness and opacity of paper, its adhesion and wear resistance are not high enough. However, due to the changing environment of paper, especially high-grade paper, the color will also change when it is exposed to moisture and heat. Larger changes are prone to discoloration or even fading. In addition, high-grade paper also has higher requirements for wear resistance and shaping. The existing wear resistance of paper modified with titanium dioxide cannot meet the needs of us...
