Abstract
The invention relates to an impregnant composite for treating a cellulose material and a method for treating the cellulose material by the impregnant composite. The impregnant composite contains the following ingredients: a) 1-40 wt% of reactive monomer capable of generating an esterification-polymerization reaction; b) 1-30 wt% of water-soluble polymer; c) 0-15 wt% of monomer containing unsaturated bonds, 0-5 wt% of initiator and 0-10 wt% of polymerization catalyst; and d) 30-90 wt% of solvent. The cellulose material treated by the cellulose material has the advantages of less pores inside, large density, high hardness and good size stability.
Description
Technical field
