Hydrophobic raw paper material for packing cartons and preparation method thereof

Abstract

The invention discloses a hydrophobic raw paper material for packing cartons. The raw paper material is prepared from the following raw materials in parts by weight: 0.7 to 1 part of dodecafluoroheptylpropyltrimethoxysilane, 2 to 3 parts of polyethylene benzene sulfonic acid, 0.3 to 1 part of polyglycerol fatty acid ester, 1 to 2 parts of diphenyl imidazoline, 0.4 to 1 part of triethanolamine, 0.1 to 0.3 part of trichloroisocyanuric acid, 1 to 2 parts of octyl isothiazolinone, 3 to 4 parts of calcium hydrogen phosphate, 4 to 7 parts of beeswax, 0.1 to 0.2 part of polyoxypropylene glycerol ether, 0.6 to 1 part of beta-hydroxyalkylamide, 2 to 4 parts of isooctyl methacrylate, 0.8 to 2 parts of diazolidinyl urea, 15 to 20 parts of tetrabutyl titanate, 0.7 to 1 part of hexafluoroacetylacetone, 110 to 130 parts of waste paper pulp, 0.1 to 0.2 part of divinyl benzene, 0.5 to 1 part of calcium naphthenate, 20 to 30 parts of polyester fiber, 5 to 7 parts of polyether glycol, and 1 to 2 parts of stearic acid. Obtained modified sol is processed by dodecafluoroheptylpropyltrimethoxysilane so as to obtain a sol dispersion liquid with good hydrophobicity, the raw paper material can be normally used in a damp environment and the comprehensive performance of packing cartons is enhanced.

Description

technical field [0001] The invention relates to the technical field of packaging carton materials, in particular to a hydrophobic base paper material for packaging cartons and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the use of packaging cartons has become wider and wider, including not only traditional daily necessities, but also various aquatic products, fresh food, chemicals, etc., which requires packaging cartons It has better protection performance. Some traditional packaging cartons use cotton linters and other materials. The pulp fibers made of these have long lengths, very curved fibers, poor dimensional stability, and strong water absorption. It is easy to be damaged. At the same time, paper materials, as one of the commonly used materials, are areas closely related to people's lives. People may come into contact with packaging cartons everywhere in their lives.
