[0005] Aiming at the deficiencies of the prior art, the present invention provides a paper-making filler additive and a preparation method thereof, which solves the problem that kaolin is used in the largest amount as a paper-making filler, and has the advantage of low price, and the disadvantage of uneven particle size and poor brightness. At present, due to titanium source Factors such as shortage and high price, and the difficulty of recycling nano-scale titanium dioxide limit the wide application of titanium dioxide.

Abstract
The invention discloses a papermaking filler additive and a preparation method thereof. The papermaking filler additive comprises the following raw materials in parts by weight: 80-100 parts of original diatomite, 5-10 parts of titanium dioxide composite powder, 6-8 parts of modified fly ash, 1-3 parts of wollastonite fibers and 20-30 parts of a composite flocculant. According to the papermaking filler additive and the preparation method thereof, the excellent characteristics of kaolin and titanium dioxide can be fully combined through the titanium dioxide composite powder, titanium dioxide nanoparticles are deposited on the surface of a kaolin substrate to keep the photocatalytic activity of the kaolin substrate, and the titanium dioxide nanoparticles are non-toxic and pollution-free and have the advantages of high refractive index, high whiteness and the like of surface titanium dioxide; the pigment performance is effectively improved, and the cost is reduced; and a diatomite part and an organic molecular chain contained in the composite structure of the composite flocculant are both negatively charged, the molecular chain can freely stretch due to the electrostatic repulsion effect between the diatomite part and the organic molecular chain, the molecular chain is not interfered by the entanglement effect, the branching degree of the molecules of the composite flocculant is high, and the steric hindrance is large.
Description
Technical field [0001] The present invention relates to the technical field of papermaking, particularly to a papermaking filler additives and preparation method. Background technique [0002] my country's paper industry continuously toward high-speed, continuous, large-scale direction of development, labor productivity continues to increase, due to a lack of resources softwood, hardwood and use of grass-based raw materials is increasing, more and more waste paper recycling rate high, and therefore, increase the fine component content in the slurry. Also, because of water shortages and pollution prevention requirements worldwide, it must be closed so that the water recycling paper. In this case, the save energy and reduce the consumption of pulp and papermaking drainage reduce the processing load of view, should retention of fines and filler in the slurry, while also maximized by dewatering the wet end section. The most economical way is to use efficient paper additives. [0003]...
