Abstract
The invention discloses a papermaking retention aid and a preparation method therefor. The papermaking retention aid contains the following ingredients in parts by weight: 10-20 parts of bentonite, 10-30 parts of calcite, 12-20 parts of attapulgite, 15-30 parts of acicular-powder wollastonite, 5-15 parts of talcum, 2-5 parts of chitosan, 5-8 parts of polyacrylamide, 5-8 parts of glacial acetic acid and 100-150 parts of water. The papermaking retention aid has the advantages that the papermaking retention aid adopts a variety of nonmetallic minerals and other ingredients, so that the rate of retention of short fibers in paper pulp can be effectively increased, the fibrous structure of the paper pulp is improved, and the quality of paper sheets is improved; meanwhile, the input of raw materials of the paper pulp is reduced, and the consumption of the paper pulp is lowered; in addition, fibers in papermaking wastewater are reduced, and suspended substances and COD are reduced. The preparation method for the papermaking retention aid is easy and feasible, is free of dust pollution and is low in cost and easy to implement.
Description
Technical field
The present invention relates to a kind of chemical products, particularly relate to a kind of Retention Aid in Papermaking and preparation method thereof.
Background technology
Existing Retention Aid in Papermaking is strong to the fibers adsorption effect of paper pulp, and an obtained paper pulp fiber is loosely organized, paper fineness, flatness are poor, cannot meeting the market requirement; Two come to consume too much paper pulp, raising manufacturing cost.
Summary of the invention
Goal of the invention: the first object of the present invention is to provide a kind of retention, the Retention Aid in Papermaking that improves paper quality that can increase fiber in paper pulp; The second object of the present invention is to provide the preparation method of this Retention Aid in Papermaking.
Technical scheme: Retention Aid in Papermaking of the present invention, comprises the component of following weight portion: bentonite 10-20 part, calcite 10-30 part, attapulgite 12-20 part, acicular powder wollastonite 15-30 part, talcum 5-15 part, shitosan 2-5 part, polyacrylamide 5-8 part, glacial acetic acid 5-8 part, water 100-150 part.
Wherein, described bentonite 15 parts, 20 parts, calcite, attapulgite 15 parts, acicular powder wollastonite 20 parts, 10 parts, talcum, shitosan 4 parts, polyacrylamide 6 parts, 7 parts, glacial acetic acid, 120 parts, water.
The preparation method of Retention Aid in Papermaking of the present invention, comprises the steps:
(1) bentonite 10-20 part, calcite 10-30 part, attapulgite 12-20 part, acicular powder wollastonite 15-30 part, talcum 5-15 part being ground to form fineness is 800-1100 object pressed powder;
(2) shitosan 2-5 part, polyacrylamide 5-8 part, glacial acetic acid 5-8 part are added to the water successively, are made into turbid liquid, then this turbid liquid is standing, layering obtains decorating film, and is dried, pulverizes to obtain another pressed powder by this decorating film;
(3) above-mentioned two kinds of pressed powders are mixed, obtain Retention Aid in Papermaking.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: this Retention Aid in Papermaking adopts multiple nonmetallic mineral and other component, effectively can improve the short-and-medium fibrillose retention of paper pulp, improve the fibre structure of paper pulp, improves paper quality; Decrease the input of paper pulp raw material simultaneously, reduce the consumption of paper pulp; Make fiber in paper waste reduce in addition, suspended matter and COD reduce.Processing method of the present invention is simple, no dust pollution, with low cost, easily realize.
