Abstract

The applicability of the developed binary system of synthetic compounds in coating paste, consisting of urea-formaldehyde oligomer (2 pts. wt. to the coating paste weight) and latex (16 pts. wt.), is found. It replaces the generally used complex of natural compounds, such as modified starch (3 pts. wt.), Na-CMC (2 pts. wt.), and casein glue (1 pts. wt.), in the presence of latex (16–32 pts. wt.). The properties of the coating paste samples met the standards, as evidenced by the viscosity according to the viscometer VZ-4 (13–17 s), the content of dry substances (50–54 %) and pH (9.0–10.5). The proposed urea-formaldehyde oligomer is combined with the present components and, as compared to natural compounds, does not increase the viscosity of the coating paste, has a high cohesive force, participating in the binding of pigment particles with one another, has the necessary adhesive capacity for ensuring a stable bond of the applied coating layer with the surface of paper and cardboard, does not prevent the uniform distribution of pigment particles on the base surface, and gives stability to the coating paste. These phenomena can be explained by the supplementary presence of positively charged nitrogen-containing groups (amine and amide) in the urea formaldehyde oligomer. The latter contribute to the enhancement of cohesive and adhesive interactions in coating pastes and coatings composed of them. Assessment of a section of the coated paper (cardboard) showed that one part of the binder adjoins the base (paper, cardboard) penetrating into its pores and capillaries, the other surrounds the pigment particles, and the third occupies (completely or partially) the spaces between the particles. An increase in the surface resistance to plucking and breaking length by 6.0–8.5 and 15–20 %, respectively, is shown on the samples of light-coated newsprint and polygraphic cardboard. This allows considering the urea-formaldehyde oligomer as an alternative to natural compounds. Herewith, whiteness (85–87 %) and smoothness (250–265 s) meet the requirements. Changing the formulation of the coating paste is economically justified, since material costs for the production of coated paper and cardboard products are reduced by 1–2 %.
