Abstract
The invention discloses a papermaking retention and drainage aid and a preparation method therefor. The papermaking retention and drainage aid contains the following ingredients in parts by weight: 20-30 parts of acryloyl chloride, 20-50 parts of acrylamide, 20-30 parts of talcum powder, 0.1-2 parts of ammonium persulfate, 2-5 parts of fumaric acid, 10-15 parts of kaolin, 15-20 parts of silicon dioxide, 5-8 parts of urea, 5-8 parts of isopropanol, 0.05-2 parts of dodecyl mercaptan and 200-300 parts of water. The papermaking retention and drainage aid has the advantages that the papermaking retention and drainage aid can be used for increasing the rate of retention of fines in pulp and improving the drainability of paper stock, and the quality of prepared paper sheets is high; and meanwhile, the preparation method for the papermaking retention and drainage aid is easy and feasible 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 paper retention and filter aid and preparation method thereof.
Background technology
The retention of existing paper retention and filter aid to the tiny component of paper pulp is not high, makes the water filtering performance of paper stock poor, and obtained paper quality is not high.
Summary of the invention
Goal of the invention: the first object of the present invention is to provide a kind of retention, the paper retention and filter aid that improves paper quality that can increase trickle component in paper pulp; The second object of the present invention is to provide the preparation method of this paper retention and filter aid.
Technical scheme: paper retention and filter aid of the present invention, comprises the component of following weight part: acrylate chloride 20-30 part, acrylamide 20-50 part, talcum powder 20-30 part, ammonium persulphate 0.1-2 part, fumaric acid 2-5 part, kaolin 10-15 part, silica 1 5-20 part, urea 5-8 part, Virahol 5-8 part, lauryl mercaptan 0.05-2 part and water 200-300 part.
Wherein, described acrylate chloride 25 parts, acrylamide 30 parts, talcum powder 25 parts, ammonium persulphate 1 part, fumaric acid 3 parts, kaolin 12 parts, silica 18 parts, 7 parts, urea, Virahol 7 parts, lauryl mercaptan 1 part and 250 parts, water.
The preparation method of paper retention and filter aid of the present invention, it is characterized in that comprising the steps: acrylate chloride 20-30 part, acrylamide 20-50 part, talcum powder 20-30 part, ammonium persulphate 0.1-2 part, fumaric acid 2-5 part, kaolin 10-15 part, silica 1 5-20 part, urea 5-8 part, Virahol 5-8 part, lauryl mercaptan 0.05-2 part to be added to the water successively, regulate pH between 5-6, pass into nitrogen deoxygenation, be heated to 50-70 DEG C simultaneously, heat while stirring until liquid becomes thick.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: this paper retention and filter aid can improve the retention of tiny component in slurry, improves the water filtering performance of paper stock, and obtained paper quality is high; Meanwhile, preparation method of the present invention simple, with low cost, easily realize.
