Description
Technical field
The invention belongs to chemical fields, and in particular to a kind of Study of Paper-Strengthening Agent Based.
Background technique
Drying strengthening agent be in paper industry enhance paper strength a kind of important chemical, commonly used in compensation addition filler or
The decline of paper intensity caused by the fiber of inferior grade.In recent years, waste paper resources utilization rate rises year by year, and development potentiality is huge
Greatly.But the raising of waste paper utilization rate means that the increase of number is recycled in waste paper, will cause declining to a great extent for paper intensity index,
So needing to add drying strengthening agent to increase paper strength.Continuous rising with people to paper and cardboard demand pulls
The swift and violent growth of drying strengthening agent demand.Study of Paper-Strengthening Agent Based has been widely used in the production process of all kinds of paper and paper, to
It dramatically increases the dry strength of paper and cardboard, reduces high-quality raw material consumption, improves product specification, constantly proposed with to meet user
Higher and higher quality requirement.Paper is mainly to be made of paper fiber through network structure, and paper has a layer structure, in plane
Paper fiber is interlaced, disordered arrangements, and paper also has pore structure.Therefore, although at paper intensity by many factors shadow
It rings, but the binding force between most important reason or paper fiber.If can be led in paper containing largely unbonded staple fiber
Paper strength is caused to be decreased obviously, this not only has an impact performance, the quality at paper, also will affect the runnability of paper machine, drops
Low production efficiency.Therefore in the production process of papermaking, by the use of papermaking dry-strengthening agent, paper quality can be improved, reduced
Production cost, retention in addition also can be improved, increase paper formation, the runnability for improving paper machine etc..
The structure of paper fiber is determined containing the functional groups that can form Hydrogenbond with paper fiber（Hydroxyl, amide groups）
Water-soluble polymer can be used as papermaking dry-strengthening agent.Currently used drying strengthening agent has natural polymer such as starch and its modification
Object（Such as cationic starch, anionic starch, amphoteric starch）, synthetic polymer such as polyacrylamide, glyoxal polyacrylamide
Amine and polyvinyl alcohol etc. and other water-soluble natural product type drying strengthening agents.In most cases, mass fraction is only added
0.1% ~ 1% substance can reach does potent fruit well.But produce in actual use paper folding strength,
Pop strength is poor.Therefore, producing a kind of drying strengthening agent that can solve the above problem has the very big market demand.
