Problems solved by technology

Using bamboo pulp to make auxiliary pulp to produce calligraphy and painting paper, although to a certain extent alleviated the problem of shortage of raw material sources, inevitably leads to a decline in product quality, and even fails to meet the requirements of quality standards
Bamboo pulp and some auxiliary materials contain high hemicellulose content, and contain a small amount of impurities such as protein, pectin, and miscellaneous cells, resulting in low porosity, low bulk, poor water absorption, and poor air permeability of calligraphy and painting paper, which further leads to paper. Poor anti-bacterial and anti-corrosion properties, and some defects in ink wetting
[0005] Based on the current situation of machine-made calligraphy and painting paper due to the poor antibacterial ability of raw materials and paper sheets, it is necessary to find a low-cost, high-efficiency antibacterial and anti-corrosion process to make up for the shortcomings of poor durability of machine-made painting and calligraphy paper; Sexual adjustment method to produce calligraphy and painting paper with different ink moistening properties to meet the needs of different groups of people

Abstract

The invention discloses an antibacterial writing and painting paper having a controllable wetting property, and a making method thereof. The antibacterial writing and painting paper having a controllable wetting property comprises raw materials and assistants, the raw materials comprise, by weight, 50-70 parts of bleached bamboo pulp fibers and 30-50 parts of Eulaliopsis binata fibers, and the assistants (by absolutely dry slurry) comprise, by weight, 0.8-1.6 parts of a composite antibacterial agent, 0.1-0.4 part of a dispersant, 0.05-0.1 part of a retention aid and 1.0-10.0 parts of light calcium carbonate. Chitosan and the inorganic silver ion composite antibacterial agent are used to realize antibacterial and anticorrosive effects and utilize the enhancement effect of the chitosan, so various strength indexes of the paper are improved; and the use amount of the light calcium carbonate is controlled to improve the wetting property of the paper, so the applicability of the writing and painting paper is improved.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to an antibacterial calligraphy and painting paper with controllable wettability and a preparation method thereof. Background technique [0002] Calligraphy and painting paper is a special paper for calligraphy and painting in our country, and it is one of the "four treasures of the study" in our country. There are many performance indicators of calligraphy and painting paper, mainly including the absorbency, ink wetting, durability and some strength indicators of the paper. The absorbency and ink-wetting properties of paper are mainly related to the fiber raw materials used in production, while the antibacterial and anti-corrosion properties of paper are mainly determined by the production process. [0003] At present, calligraphy and painting paper is mainly made of cotton, hemp, leather and other raw materials, compounded with some short-fiber pulp such as broad-...
