Abstract

The invention discloses paper news media. The paper news media is prepared from, by weight, 60 parts of deinking chemical pulp, 18 parts of bamboo alkaline hydrogen peroxide mechanical pulp, 7 parts of bamboo chemical hot grinding mechanical pulp, 15 parts of aspen alkaline hydrogen peroxide hot grinding mechanical pulp, 0.03-0.08 part of brightener, 8-15 parts of filler, 0.5-1.5 parts of enhancer, 0.3-1 part of retention and drainage aid and 0.1-0.3 part of sizing agent. The prepared paper news media is high in brightness, opaqueness and strength and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of newsprint, in particular to a paper news medium. Background technique [0002] Newsprint is the main paper for newspapers and books. It needs to meet the characteristics of light weight, good elasticity, good ink absorption performance, certain mechanical strength and good opacity. my country is a big country in paper production, consumption and import. With the growth of demand for paper products in my country, the supply of wood pulp is far from meeting the demand, resulting in a rapid increase in import volume. Wood fiber is much higher than non-wood fiber in terms of performance and technology, but my country's forestry resources are scarce, and the supply of wood fiber in my country is on a downward trend. [0003] Waste paper is recycled as a renewable resource. Compared with straw pulping, waste paper pulping can save a lot of energy, because the use of deinking pulp does not require the cooking s...
