A kind of fluorescent ASA papermaking sizing agent and preparation method thereof

Abstract

The invention relates to a fluorescent alkenyl succinic anhydride (ASA) sizing agent for papermaking and a preparation method of the fluorescent ASA sizing agent for papermaking, belonging to the technical field of sizing agent for papermaking. According to the fluorescent ASA sizing agent for papermaking, firstly, a carbon quantum dot is added into the ASA sizing agent, so that ASA sizing emulsion which can be used as the fluorescent sizing agent for papermaking and effectively improves the water resistance of paper is successfully prepared; a new emulsion stabilizer is provided for the ASA sizing agent, and the stable emulsifying agent enables the sizing agent to have fluorescence property and high sizing efficiency; furthermore, the emulsion stabilizer serving as the carbon quantum dot has the advantages of being few in dosage, non-toxic, low in cost, etc. The fluorescent ASA sizing agent for papermaking adopts a simple preparation technology, and a surface active agent, a polymer polyelectrolyte and a dye type fluorescent agent do not need to be added into the fluorescent ASA sizing agent.

Description

technical field

[0001] The invention relates to a functional sizing agent in the field of papermaking, in particular to a fluorescent ASA papermaking sizing agent and a preparation method thereof. Background technique

[0002] The transformation of the papermaking industry from acidic papermaking system to medium and alkaline papermaking is an innovative change in the papermaking process in the 20th century. This can not only improve the quality of paper and expand the range of fillers, but also reduce pulp consumption, reduce energy consumption, and reduce environmental pollution. Extend the life of equipment. According to statistics, in the early 1980s in Europe, cultural paper produced by medium and alkaline sizing accounted for 60% to 65% of the total cultural paper, and it reached 95% in the 1990s. The proportion of alkaline sizing jumped from 15% to over 90%. my country has used medium and alkaline sizing in production since 1989, and it has gradually become popular ...
