Painting paper added with blanching bamboo pulp meal and fiber grafting agent and preparation method of painting paper

Abstract

The invention relates to the technical field of papermaking, in particular relates to a manufacturing technique of painting paper, and more particularly relates to a method for preparing the painting paper by adding the blanching bamboo pulp meal and the fiber grafting agent. The painting paper is characterized by comprising pulp material and auxiliary materials, wherein the pulp material comprises 20wt%-90wt% of blanching bamboo pulp and 10-80wt% of blanching bamboo pulp meal, and based on the weight of the pulp material, the auxiliary materials comprise 0.5wt%-1.5wt% of talcum powder, 0.05wt%-1.0wt% of the fiber grafting agent and 0.1wt%-1.0wt% of oleander glue. The painting paper has the characteristics of low compactness, high bulk, large fracture length, good water-absorbing quality, high toughness, high ink absorption, high size stability and low yellowing rate, is hardly prone to damage by worm or mildewing, and be can stored for a long time; the preparation method is simple, easy to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a calligraphy and painting paper added with bleached bamboo pulp and a fiber grafting agent and a preparation method thereof. Background technique [0002] Calligraphy and painting paper is one of the "four treasures of the study" in my country. Good painting and calligraphy paper is deeply loved by calligraphers, painters and calligraphy and painting lovers. A good painting and calligraphy paper should have good ink, color and wettability. In addition to whiteness and strength, it should also have certain quality indicators such as stiffness, bulk and water absorption. [0003] At present, leather and cotton are mainly used as the main raw materials for processing and production. Leather and cotton raw materials have the advantages of high cellulose content and low content of lignin, hemicellulose, and miscellaneous cells. The quality of the calligraphy and painting paper p...

AI Technical Summary

Problems solved by technology

At present, bamboo pulp production enterprises are basically in a state of on and off, and the operating rate is low. The reason for the analysis is that the chemical indicators such as cellulose content, ash content, whiteness and viscosity of the produced bamboo pulp can reach the level of chemical fiber. Factory standard requirements, but there are problems such as poor reaction performance, which is manifested in the production of viscose fibers in chemical fiber factories. Due to poor reaction performance, the viscose made has poor filtration performance, and the color is turbid and dark, which affects the smooth progress of the entire subsequent chemical processing. In severe cases, all the viscose liquid will be scrapped, which will lead to difficulties in selling bamboo pulp, and a large amount of bamboo pulp will be hoarded in the production enterprise, which will directly affect the economic benefits and sustainable and stable development of the enterprise.
