Description
Technical field
The invention relates to a kind of good paper for lithographic printing, particularly newsprinting paper for lithopraphic printing that is suitable for colored printing.
Background technology
In recent years, printing technology is highly progressive, and the thing followed is the requirement for printing to lithographic printingization, at a high speed a large amount of printingization, automation etc., and aspects such as its operation, printing grade of fit also need be improved.
Particularly lithographic printing owing to use ink and liquid simultaneously in printing machine, is compared with known letterpress the burden with paper, becomes big significantly, and therefore, for paper for lithographic printing, it is necessary having appropriateness suction repellence (promptly going up colloidality).
Give the method for colloidality on the printing, add glue and the outer two kinds of methods of glue (surface sizing) of adding in having, the former adds in the so-called green end, add jelly (for example: rosin size agent, fortified rosin size agent, neutral rosin size agent, alkyl ketene dimer (AKD), fat alkenyl succinic acid anhydride (ASA) etc.) in paper pulp, adding, for in papermaking, make the inside of paper contain the method for medicine; The latter is, after papermaking, utilize representativenesses such as glue pressing machine or cast gate roll coater to be coated with worker's machine, the method that is coated with surface sizing agent (for example: styrene/maleic acid based copolymer, styrene/acrylic based copolymer, alkene/maleic acid based copolymer, urethane based copolymer etc.).
But, in add glue in (1) medicine must make an addition in the low concentration paper pulp, the adhesion amount of (2) medicine on the paper seat not necessarily all have problems in aspects such as cost, quality, operability such as (the medicine adhesion amount is low), (3) plain boiled water pollution, opposite, owing to add the problems that glue is added glue in not having outward, be feasible method.
On the other hand, as the surface strength countermeasure of printing, carrying out surface coated with starch, chemical starch, polyvinyl alcohol (PVA) or polyacrylamide water soluble polymers such as (PAM) is conventional method, therefore, add outside in the glue, surface sizing agent and these materials are also used to basic.
For example, to contain the styrenic monomers water solubility copolymer is the surface sizing agent (agent of polystyrene surface sizing) of main body and the prescription of starch and usefulness etc., widely popularize, can list: the spy opens clear 60-185894 communique, spy and opens flat 5-247888 communique, spy and open flat 11-140791 communique etc. and be example.
