Problems solved by technology

[0003] There are many kinds of sizing agents, and the internal sizing agents mainly include rosin, unmodified and modified starch PVA, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA); the surface sizing agent has modified And unmodified starch, paraffin emulsion, carboxymethyl cellulose and styrene-maleic anhydride copolymer, etc., the emulsifier needs to be used in the production process of the sizing agent. The function of the current emulsifier is relatively single, and the emulsifying effect is limited. Can not meet the needs of modern use

Abstract

The invention relates to the technical field of emulsifiers, and particularly, relates to a special emulsifier for a papermaking sizing agent. The special emulsifier comprises the following raw materials in parts by weight: 40 to 60 parts of sodium aliphatate, 25 to 40 parts of ethylenediamine, 10 to 20 parts of alkenyl succinic anhydride, 5 to 15 parts of epoxy chloropropane, 20 to 30 parts of triethylamine, 3 to 12 parts of fatty alcohol-polyoxyethylene ether and 20 to 30 parts of lauryl sodium sulfate. The emulsifier produced by adopting the formula and the process is scientific and simplein formula, concise in preparation process and good in emulsifying effect, and the binding power of paper can be improved, so that the paper has wear resistance, acid and alkali resistance and water resistance, and is high in functionality.

Description

technical field [0001] The invention relates to the technical field of emulsifiers, in particular to a special emulsifier for papermaking sizing agents. Background technique [0002] Papermaking is an important invention of the working people in ancient China. There are two forms of mechanism and manual. The mechanism is carried out continuously on the paper machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and is initially dehydrated in the wire part of the paper machine to form a wet paper sheet, which is then dehydrated by pressing, and then dried into paper. In order to improve the surface strength of paper and paperboard and prevent the diffusion and penetration of aqueous liquids, it is necessary to carry out sizing treatment on paper and paperboard. Added additives are called paper sizing agents. [0003] There are many kinds of sizing agents. The internal sizing agents mainly include rosin, unmodified and modified starc...
