ABSTRACT
Development of new and modification of existing chemicals, which act not only as binders, but also provide increased retention of fiber and other pulp components on the paper machine grid, accelerate pulp dehydration, and provide special properties (moisture resistance, heat resistance, improvement of other technical characteristics of paper and cardboard) of paper and cardboard, is an important and urgent task of chemical technology and ecology. This paper presents results of the corn starch modification with epoxypropyltriethanolammonium chloride, hexamethylolmelamine and hexamethylenetetramine. Modified starches provide the necessary strength indicators of cardboard from waste paper and low turbidity of wastewater. The obtained starches can be used in mills that use low-quality waste paper for the production of cardboard and paper products with the aim of saving fiber, reducing wastewater pollution and as a result reducing the negative impact on the environment.
