Abstract

The present invention provides a modified wollastonite mineral composite fibre for making paper and its paper-making method. It includes the following steps: breaking wollastonite raw ore to obtain the thin-long fibre whose grain size is 5-20 micrometer and the ratio of mid-diameter:length=1:6-30, and according to the ratio of alkali or salt of aluminium: alkali or salt of sodium=1:1 adding modification agent whose added quantity is 3-10% of wollastonite mineral composite fibre weight so as to obtain the wollastonite mineral composite fibre covered with modification agent. In the course of preparing pulp in paper-making process 5-50% of modified wollastonite mineral composite fibre and 50-95% of plant fibre and paper-making auxiliary material are added, it can reduce production cost.

Description

technical field

[0001] The invention relates to a modified wollastonite mineral composite fiber for papermaking instead of plant fibers and a papermaking method using the modified wollastonite mineral composite fiber. Background technique

[0002] At present, most of the raw materials used in the papermaking industry are plant fibers, which consume a large amount of wood resources every year. At the same time, excessive deforestation has also caused serious deterioration of the ecological environment. And paper is indispensable and necessary in human production and life. As far as the demand for paper products in my country is concerned, it is increasing at a rate of 10% every year. The sustainable development of the paper industry is facing serious challenges. The shortage of paper raw materials has restricted my country. The development of the paper industry, therefore, the paper industry has been looking for other paper fibers that can replace plant fibers for a long time,...
