Abstract

The invention discloses a water-resistant oil-dispersion-resistant rosin size and a preparation method thereof. The water-resistant oil-dispersion-resistant rosin size is characterized by comprising,50-60% of rosin size, 30-40% of rosin maleic anhydride polyol ester, 20-30% of rosin, 20-30% of anhydride, 9-13% of oligomeric surfactant, 8-12% of reinforced rosin size, 8-10% of petroleum wax, 10-12% of tall oil, 8-10% of oxidized polyethylene wax, 6-8% of emulsifier, 15-25% of a tricyclic diterpene oxygen-containing compound, 10-14% of polyacrylamide dispersant, 1-2% of catalyst, 20-30% of polyethylene glycol, 30-40% of alkylene oxide, 10-12% of antioxidant and 6-9% of esterifying agent. The water-resistant oil-dispersion-resistant rosin size has the technical effects that the rosin size prepared by the formula and the preparation process has relatively high water resistance, oil resistance and dispersity.

Description

technical field [0001] The invention relates to the technical field of rosin gum and its preparation process, in particular to a water-resistant and oil-resistant dispersed rosin gum and a preparation method thereof. Background technique [0002] Sizing refers to a method of treating paper or board. The purpose of paper sizing is to render the paper resistant to penetration by fluids. With the exception of a few specialty papers, almost all papers require varying degrees of sizing. Sizing methods include internal sizing and surface sizing, in which internal sizing is also called paper internal sizing, adding sizing agent to pulp in the wet end process, which is a commonly used sizing method. The sizing agent is divided into two categories: rosin type and non-rosin type. Rosin-type sizing agents mainly use rosin, mainly including rosin glue, reinforced rosin glue, paraffin rosin glue, and dispersed rosin glue. High free rosin gum. Non-rosin sizing agents mainly include p...
