Abstract

The invention relates to a paraffin sizing agent and a preparation method thereof. The paraffin sizing agent is prepared from the following components in parts by weight: 15-18 parts of paraffin, 4-7 parts of methyl glucose dioleate, 5-6 parts of diethylene glycol monolaurate, 3-4 parts of sodium alga acid, 2-4 parts of polyvinyl alcohol, 4-5 parts of oxidized starch and 130-134 parts of deionized water. The components of the paraffin sizing agent disclosed by the invention are dissolved, agitated and sheared to prepare the paraffin sizing agent. The prepared paraffin sizing agent has a high sizing degree, and the surface strength of paper can be improved.

Description

technical field [0001] The invention relates to a sizing agent and a preparation method thereof, in particular to a paraffin wax sizing agent with higher sizing degree and improved paper surface strength and a preparation method thereof. Background technique [0002] The sizing process, as an integral part of the papermaking process, imparts water, oil and corrosion resistance to the paper, while also improving the smoothness of the paper. Paraffin wax sizing agents generally use surfactants to evenly disperse paraffin wax on the surface of paper to improve the performance of paper. [0003] After conventional paper is treated with paraffin sizing agent, its sizing degree is not high, and its surface strength is also low, which limits the use of paper. By compounding paraffin wax with other formula components, giving paraffin wax sizing agent different properties may improve the surface strength of paper and expand the application field of paper.
