Abstract

The invention provides latex for papermaking. The latex contains starch, oxidants, hydrophobic modifying agents and water, wherein the dosage of the oxidants is 7-10% of the mass of starch; the dosage of the hydrophobic modifying agents is 5-20% of the mass of the starch; the hydrophobic modifying agents are selected from at least one of dodecenyl succinic anhydride, maleic anhydride, epoxy chloropropane, an alkyl ketene dimmer, alkenyl succinic anhydride, a styrene-acrylate copolymer, a silane coupling agent and a titanate coupling agent. The invention also provides a preparation method of the latex for papermaking and a coating containing the latex for papermaking. The problems that the wet strength of finished paper is poor and dusting happens easily because the paper is coated with the starch-based latex for papermaking in existing processes are solved.

Description

technical field

[0001] The invention relates to a latex used in the field of papermaking and a preparation method thereof, and also relates to a coating containing the latex for papermaking. Background technique

[0002] Starch has a wide range of sources, low price, and has the advantages of being renewable and non-polluting. At present, it is common to prepare latex for papermaking by starch modification and optimization, and partially replace petroleum-based latex. However, the paper coated with starch-based latex paint has the problem of poor paper wet strength and easy powder drop when wet. Contents of the invention

[0003] In view of this, it is necessary to provide a latex for papermaking, which can effectively overcome the shortcomings of poor paper wet strength and easy powder drop when wet.

[0004] In addition, it is also necessary to provide a preparation method of the above latex for papermaking and a coating containing the latex for papermaking.
