Study on the application of oligomers in paper reinforcement protection

Abstract

In order to improve the strength of paper, solve the problem of poor permeability of traditional resins to paper, the low molecular weight hexamethylenediisocyanate (HDI) trimer was investigated, and the chemical and physical properties of paper samples were tested in this work. Results showed the paper treated by HDI trimer had good mechanical property, the tensile strength was increased from 1105 to 4151 N/m, the folding endurance was increased from 20.8 to 275; and had good glossiness and brightness. Therefore, the prepared HDI trimer has great application prospects in the protection of paper.
