Abstract

The invention discloses an environment-friendly water-resistant reinforced latex for paper, a preparation method and application thereof, and belongs to the field of paper-making auxiliary agents. The present invention uses styrene and butyl acrylate as main reaction monomers, dicyclopentenyloxyethyl methacrylate and dimethyl itaconate as main functional monomers, sodium lauryl sulfate and nonyl Phenol polyoxyethylene ether was used as emulsifier, persulfate was used as initiator, sodium bicarbonate was used as buffer, and modified styrene-acrylic latex was synthesized by pre-emulsification seed emulsion polymerization, and prepared by compounding it with cationic starch and chitosan Environmentally friendly water-resistant reinforced latex for paper. The invention has advanced technology, no pollution, and low production cost. The straw base paper prepared by using the environmentally friendly water-resistant enhanced latex for paper of the invention has good stiffness, water resistance, heat resistance, and good printability, and has certain antibacterial properties. , can reduce bacterial contamination on the surface of straw base paper, and has a broad market application prospect.

Description

technical field [0001] The invention belongs to the production field of auxiliary agents for papermaking, and in particular relates to an environment-friendly water-resistant reinforced latex for paper and a preparation method and application thereof. Background technique [0002] With the development of plastic bans at home and abroad, fast-moving products such as plastic tableware are gradually eliminated by the market. Countries such as the European Union have proposed "plastic reduction orders". Some international fast food chain giants have gradually begun to use paper straws instead of disposable plastic straws. Therefore, it is an inevitable trend to replace plastic straws with paper straws made of natural plant fibers. Plant fibers can biodegrade and will not pollute the environment; with the development of society and the improvement of people's living standards, the environmental protection and safety of food contact materials Security puts forward higher requireme...
