METHOD FOR PREPARING POLYMER COMPOSITE MATERIAL COMPRISING HYDROPHOBIZED CELLULOSE POWDER AND POLYMER COMPOSITE MATERIAL PREPARED BY USING SAME

摘要

A method for preparing a polymer composite material comprising hydrophobized cellulose according to the present invention comprises the steps of: mixing pulp with dilution water to prepare pulp slurry at a concentration of 0.1 to 20 wt%; inducing a hydrophobization reaction by adding a hydrophobization agent to the pulp slurry; preparing dried hydrophobized cellulose by drying the pulp slurry passing through the hydrophobization reaction; preparing a hydrophobized cellulose powder by pulverizing the dried hydrophobized cellulose; and mixing the hydrophobized cellulose powder with a polymer resin. In the polymer composite material, a decrease in elongation is suppressed.;COPYRIGHT KIPO 2020
