Abstract

The invention discloses a high-efficiency compound retention aid specially used for making paper and a preparation method thereof. The high-efficiency compound retention aid specially used for making paper comprises the following raw materials in weight percentage: 5%-15% of chitosan, 10%-20% of polyaluminium chloride, 10%-20% of polyaluminium chloride, 20%-30% of cationic starch and 25%-35% of cationic polyacrylamide. The preparation method comprises the following steps of: selecting the raw materials of chitosan, polyaluminium chloride, polyaluminium chloride, cationic starch and cationic polyacrylamide, then carrying out inspection, drying, coarse crushing, fine crushing, sieving, metering, high-speed stirring and mixing and compounding to obtain the retention aid. The retention aid has the advantages of less consumption, high retention rate and high cost performance and can be widely used in the fields of textile spool paper, culture paper, toilet paper, coated paper, common yellow board packaging paper and the like.

Description

1. Technical field [0001] The invention and papermaking auxiliary raw materials specifically relate to a special retention aid for composite high-efficiency papermaking, and the invention also relates to a preparation method of the special retention aid. 2. Background technology [0002] The special retention aids for papermaking that are currently on the market have a narrow range of pH values, and cannot be applied to the surface modification of talcum powder, kaolin, heavy calcium carbonate, and light calcium carbonate at the same time, nor can they be applied to acidic, medium Papermaking under alkaline conditions, with large dosage and low retention rate. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a composite high-efficiency paper-making special retention aid with a wide range of acid and alkali applications and a high retention rate. Another object of the present invention ...
