Abstract

The invention discloses environment-friendly water-resistant reinforced latex for paper as well as a preparation method and application thereof, and belongs to the field of production of auxiliaries for papermaking. According to the method, styrene, butyl acrylate and the like are used as main reaction monomers; dicyclopentenyl oxyethyl methacrylate and dimethyl itaconate are used as main functional monomers; sodium dodecyl sulfate and nonylphenol polyoxyethylene ether are adopted as emulsifiers, persulfate is adopted as an initiator, sodium bicarbonate is adopted as a buffer agent, and modified styrene-acrylic latex is synthesized through a pre-emulsification seed emulsion polymerization process, and is compounded with cationic starch and chitosan to prepare the environment-friendly water-resistant enhanced latex for paper. The environment-friendly water-resistant enhanced latex for the paper is advanced in process, free of pollution and low in production cost; and straw base paper prepared from the environment-friendly water-resistant enhanced latex for the paper is good in stiffness, water resistance, heat resistance and printability, has a certain antibacterial property, can reduce bacterial pollution on the surface of the straw base paper, and has a wide 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...
