Preparation method of high-retention paper-making filler

Abstract

The invention relates to the technical field of paper-making filler, in particular to a preparation method of a high-retention paper-making filler. Self-made superfine fiber powder serves as a template to absorb hydrotalcite to obtain hydrotalcite powder, lemon, eucalyptus leaves and range peel essential oil are mildewed, mixed fermentation modification is conducted by means of fermentation liquidand highly dispersed hydrotalcite, and the high-retention paper-making filler is obtained finally; due to the fact that fiber surface space steric hindrance exists, the growth of hydrotalcite powderis limited, mildewing is conducted by means of biomass, the hydrotalcite powder and hydrotalcite are subjected to blend fermentation, the physical and chemical adsorption of the hydrotalcite is greatly improved, the retension performance of the hydrotalcite paper-making filler on paper fiber is increased, and meanwhile the bonding stability between the filler and paper is enhanced; part of organicmatter is degraded by microorganisms, a large number of active groups are generated, the active groups and hydroxy in the paper fiber can generate chemical bonding force, the bonding strength betweenthe paper-making filler and the paper is improved, and the method has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a preparation method of a high-retention papermaking filler. Background technique [0002] Paper is one of the four great inventions in ancient China. Together with the compass, gunpowder and printing, it provided the material and technological foundation for the prosperity of ancient Chinese culture. The invention of paper ended the complicated history of bamboo slips and slips in ancient times, and greatly promoted the spread and development of culture. Paper is the crystallization of long-term experience and wisdom of the Chinese working people, and is a sheet-shaped fiber product used for writing, printing, painting or packaging. [0003] In the paper industry, the addition of fillers is necessary. Adding fillers, on the one hand, can reduce the use of pulp fibers, thereby reducing wood consumption, saving forest resources, and reducing production costs; , so that the ...

Problems solved by technology

[0006] The technical problem mainly solved by the present invention is aimed at the current traditional hydrotalcite paper-making filler with uneven particle size, poor dispersibility, low retention rate in paper, and at the same time, it will cause the phenomenon of "powder falling" on the paper surface, and the paper has poor storage stability. problem, a preparation method of high retention paper filler is provided
