Abstract
The present invention provides a modified wollastonite mineral composite fibre for making paper and a papermaking method thereof. The method comprises the following steps: wollastonite green ore is crushed to form long and thin fibres with the average diameter of 5 to 20 mu m and the length of 1: 6 to 30; a modifying agent accounting for 3 to 10 wt% of the wollastonite mineral fibres are added according to the ratio that the alkali or the salt of aluminium: the alkali or the salt of sodium =1: 1 to obtain the wollastonite mineral composite fibres coated with the modifying agent. 5 to 50 % of modified wollastonite mineral composite fibres, and 50 to 95 % of plant fibres and auxiliary materials for papermaking are added in the process of pulp mixture in papermaking technologies to make the mixture be organically cimbined with other plant fibres to increase the retention ratio of mineral fibres. The present invention not only is favorable for reducing production cost, and the shrinkage factor of paper products, increasing the opacity and the evenness of paper products and eliminating franklinism, but also do not need to change the existing technologies and equipment. The present invention can not pollute the environment and is more favorable to protect forest resources and the ecological environment than before.
