Abstract

The invention discloses N-(4-hydroxybutyryl)-gamma-aminopropyl silane, a preparation method thereof and application of the N-(4-hydroxybutyryl)-gamma-aminopropyl silane in waterproof treatment of paper-based materials. Therefore, self-made N-(4-hydroxybutyryl)-gamma-aminopropyl silane, aminoalkyl silane and long-chain alkyl silane are subjected to multi-element hydrolysis polycondensation reaction in a water phase, and a polysilsesquioxane emulsion HAW with a dendritic structure and containing C-hydroxyl, an aminoalkyl silicon chain link and a long-chain alkyl silicon chain link in the structure is synthesized; the method comprises the following steps: firstly, preparing a water-proofing agent working solution, then taking HAW emulsion as a material A and a water-soluble amino resin curing agent as a material B, diluting, stirring and uniformly mixing the HAW emulsion and the water-soluble amino resin curing agent to prepare the two-component water-proofing agent working solution, then dipping the paper-based material into the working solution for 5-10 seconds, and drying and shaping to obtain a water-proofing effect, and the treated paper-based material is waterproof, breathable and good in stiffness.

Description

technical field [0001] The invention belongs to the field of papermaking additives, and specifically relates to a preparation method of N-(4-hydroxybutyryl)-γ-aminopropylsilane and its application in the preparation of two-component water-based silicone wax waterproofing agent and the waterproofing treatment of paper-based materials aspects of application. Background technique [0002] In recent years, social development and scientific and technological progress have increased the demand for paper waterproofing agents. It can be seen from the literature that the auxiliary agents for making paper-based materials obtain waterproofness mainly include: silicone waterproofing agents based on hydroxyl silicone emulsion and hydrogen-containing silicone emulsion, saponified rosin or dispersed rosin, paraffin wax emulsion, and alkyl ketene dimerization. Body AKD emulsion, etc. Among them, aliphatic water repellents such as saponified rosin or dispersed rosin, alkyl ketene dimer AKD ...
