Waterproof paper pulp assistant

Abstract

The invention discloses a waterproof paper pulp assistant. The waterproof paper pulp assistant is prepared from the following raw materials in parts by weight: 25-33 parts of candelilla wax, 2-4 partsof dipotassium glycyrrhizinate, 10-14 parts of polyvinyl alcohol, 1-3 parts of polyvinyl butyral, 2-4 parts of methylated amino resin, 22-24 parts of four-needle zinc oxide whiskers, 54-78 parts of liquid paraffin, 22-41 parts of polydimethylsiloxane, 1-3 parts of water-based zinc stearate, 2-4 parts of hydroxypropyl cellulose, 3-4 parts of guanidine carbonate, 1-3 parts of potassium pyrophosphate, 10-13 parts of guanidine phosphate and 1-4 of butyl titanate. When the waterproof paper pulp assistant is added in the papermaking process, formed paper can have excellent water resistance.

Description

technical field [0001] The invention relates to a water-proof pulp additive. Background technique [0002] A collective term for paper, board and converted paper. It is a sheet-like fiber product used for writing, recording, printing, painting or packaging. It is made of pulp suspended in water, deposited on the forming wire of a paper machine into an intricately intertwined fiber layer, and then pressed and dried. [0003] Traditional paper tends to quickly absorb water when exposed to water, and is easy to cause damage. Therefore, waterproof additives for paper are one of the research hotspots for those skilled in the art. It is hoped that a waterproof additive suitable for paper can be developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a water-repellent pulp additive that can make the formed paper obtain excellent water-repellent performance when added in the paper-making process. [0005] In order ...
