Abstract

The invention provides a composition for increasing hydrophobic and oleophobic behavior of paper product and method which comprises, preparing slurry from 50-100 parts of gasket material, or gasket material and pigment, high speed agitating, low speed agitating and charging 1-20 parts of bonding agent, 1-10 parts of organic fluorine resin emulsion, 0.5-15 parts of crosslinkable wax emulsion, 0.05-5 parts of flowing deformation modifier, diluting to obtain a solid content of 20-80%.

Description

technical field [0001] The invention relates to a hydrophobic and oleophobic composition, in particular to a hydrophobic and oleophobic composition for endowing paper packaging materials and products and paper disposable tableware with excellent water and oil repellency and a preparation method thereof. Background technique [0002] The impact of plastic packaging materials and products and plastic disposable tableware on the environment has aroused widespread concern, and some aspects have restricted their use. Paper packaging materials and products and paper disposable tableware are emerging high-grade materials, which are environmentally friendly, can be printed, and have certain water repellency. Moreover, it is resistant to folding, wear-resistant, recyclable and recyclable, and has no pollution to the environment. It is an ideal material to replace plastics. In recent years, paper packaging materials and products and disposable tableware have...
