Description
Technical field
The present invention relates to a kind of blue printing paper with pre-coating solution and preparation method thereof.
Background technology
The development trend of paper, particularly blue printing paper shows:
1) just develops to low grammes per square metre direction from high grammes per square metre.
2) adopt waste paper to replace wood pulp, but become the intensity difference of paper, hygroscopicity value is high.
3) adopt surface treatment to become fashion trend to body paper with the technology that remedies the body paper defective.
Be used for the requirement of above-mentioned surface-treated latex: a) significantly reduce Cobb value (hygroscopicity value); B) slaking speed is fast, and machine is just ripe under requiring.
Disclosed a kind of pre-painted adhesive of Chinese patent CN1244559A and preparing process thereof, though can reduce the infiltration of sensitization liquid to paper substrate, but higher through the Cobb value of the blue printing paper after the precoating, slaking speed is slow excessively.
Summary of the invention
The objective of the invention is to propose a kind of blue printing paper with pre-coating solution and preparation method thereof, to overcome the above-mentioned defective that prior art exists.
Described blue printing paper is used pre-coating solution, comprises the component of following parts by weight:
Said cationic latex is a kind of waterborne cation dispersion, and the weight solid content is 20～40%, and average grain diameter is 30～100nm, and pH=2～6 are to adopt the component of following parts by weight to prepare:
