Paper or paperboard amphoteric ion emulsion agent and production method thereof

Abstract

Provided is a paper or paperboard amphoteric ion emulsion agent and a production method thereof. The paper or paperboard amphoteric ion emulsion agent comprises the main raw material components of , by weight, 7.5-10.5 parts of polyvinyl alcohol, 11.5-14 parts of amylum, 1.5-2.2 parts of polyacrylamide, 1.0-2.0 parts of urea-formaldehyde resin, 2-3 parts of polymine, 0.3-0.4 part of lisothiazolinone, and 60 parts of water. The production method of the paper or paperboard amphoteric ion emulsion agent comprises that all the raw materials are weighed and obtained according to the formula, 10-30 parts of clean water are added to each electric heating reaction kettle, the polyvinyl alcohol, the amylum, and the urea-formaldehyde resin are respectively heated to the temperature of 80-90 DEG C for 50-80 minutes with the rotating speed of 50-70 revolutions per minute, the polymine is heated to 50-60 DEG C for 40-50 minutes, the polyacrylamide is dissolved at room temperature for 2-2.5 hours with the rotating speed of 30-40 revolutions per minute, the lisothiazolinone is soaked in warm water for 40 minutes and filtered by a screen of 80 meshes for further using, then the solutions of all reaction kettles are mixed, power of hydrogen (PH) value is adjusted to 6.8-8.0 by using a natrium hydroxydatum (NaOH) solution with the concentration of 2-2.5%, the mixed solution is evenly stirred after cooling down and then filtered by a polyester wire of with 800meshes, and a finished product is obtained after the qualified detection. The finished product can be added in a paper pulp pool, and can also be used in the process of paper machine wet part interlayer spraying. The paper or paperboard amphoteric ion emulsion agent and the production method thereof are energy conserving, environment friendly, clear in production, no toxic, no palliative and high in paper pass rate.

Description

【Technical field】 [0001] The invention relates to an emulsion agent, in particular to a paper or cardboard zwitterionic emulsion agent used in the papermaking industry; meanwhile, it also relates to a production method of the emulsion agent. Zwitterionic emulsion products are suitable for liner board, kraft cardboard, imitation kraft cardboard, T paper (packaging lining paper), high (medium) strength corrugated base paper, coated white board paper and (A, B grade) bobbin base paper . 【Background technique】 [0002] At present, the production of paper or cardboard products from recycled paper in my country generally suffers from high consumption and poor paper quality, and the physical and technical indicators of paper or cardboard cannot meet the national standard. CN200910048093.4 discloses a modified treatment process for regenerated pulp, which includes three processes of deinking, chemical bleaching and sheeting, characterized in that it is also treated with alkaline pr...
