Embodiment 1

[0019] Composition of surface sizing solution: 70% surface sizing starch, 30% polyvinyl alcohol (PVA1788), which is made into an aqueous solution with a surface sizing solution having a solid content of 7%. The sizing solution was applied to the surface of the sheet of synthetic calcium silicate plus filled offset printing paper by means of a surface sizing machine, and the surface sizing amount was controlled to be 1.5g / m2 2 . The sizing paper is dried and then subjected to calendering treatment to obtain a finished offset printing paper.

[0020] The properties of the offset printing paper before and after the above surface treatment are shown in Table 1.

Embodiment 2

[0024] The composition of the surface sizing solution: 70% surface sizing starch, 28% polyvinyl alcohol (PVA1799) and 2% AKD, each composition was prepared with water into an aqueous solution with a surface sizing solution having a solid content of 10%. The sizing solution was applied to the surface of the sheet of synthetic calcium silicate plus filled offset printing paper by means of a surface sizing machine, and the surface sizing amount was controlled to be 2.0g / m2 2 . The sizing paper is dried and then subjected to calendering treatment to obtain a finished offset printing paper.

[0025] The properties of offset printing paper before and after surface treatment are shown in Table 2.

Abstract

The invention relates to a method for treating the surface of synthetic calcium silicate filled offset printing paper. The method comprises the following steps of sizing surfaces of prepared synthetic calcium filled silicate offset printing paper sheets by using a sizing solution which at least comprises a macromolecular compound with a film-forming property and surface sizing starch. According to the method, the surfaces of the paper sheets are treated by a composite sizing agent with relatively high water resistance, so that problems that the paper is low in sizing degree and high in absorption performance can be effectively solved; and the therefore, the synthetic calcium silicate filled offset printing paper has relatively high surface strength and proper ink absorption performance.

Description

technical field [0001] The invention relates to a surface treatment method for synthesizing calcium silicate and filling offset printing paper, and belongs to the field of papermaking. Background technique [0002] Offset printing paper is referred to as offset printing paper, and the weight is generally 60~150g / m 2 , is a kind of high-grade paper suitable for offset printing, which requires white, smooth, impurity-free paper surface, good surface strength, suitable ink absorption and morphological stability. Therefore, there are relatively high requirements for the selection and use of fillers in the manufacture of offset printing paper. [0003] With the development of the power and energy industries, research and development in the surrounding fields has been driven. Especially with the construction and use of large-scale power plants, comprehensive utilization technologies for wastes such as fly ash discharged from power plants are also constantly being developed. For...
