Від 2013 року кафедра має назву "Технологія пластичних мас і біологічно активних полімерів", первісна назва – кафедра технології пластичних мас.

Кафедра технології пластичних мас заснована в 1959 році у складі факультету технології органічних речовин. У 1985 році увійшла до складу факультету інтегрованих технологій та хімічної техніки.

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут". За період свого існування кафедра підготувала понад 3000 спеціалістів за денною, вечірньою та заочною формами навчання.

У складі науково-педагогічного колективу кафедри працюють: 6 кандидатів технічних наук, 1 кандидат хімічних наук, 1 доктор філософії; 1 співробітник має звання професора, 6 – доцента.

    Corrosion-resistant epoxy coating for protection of structural glued-laminated timber in high humidity conditions
    (2021) Skripinets, A.; Saienko, N.; Cherkashina, A. N.
    The article presents a solution to practical problem - the development of epoxy coating of low combustibility with corrosion-resistant properties for the protection of glued-laminated timber in conditions of high humidity. Based on the test results obtained, it was found that when using the developed epoxy polymer protective coating, the resistance of wooden beams to distilled and seawater increases by more than two orders of magnitude, ensuring the integrity of wood products and structures, protecting the ends and not causing warping of the material. In conditions of medium aggressiveness of the environment i.e. 10% H₂SO₄, 10% NaOH, 10% NaCl, the application of the developed epoxy polymer coating to glued-laminated timber provides their high indicators of bio- and chemical corrosion protection (water resistance, resistance to sea water and aggressive aqueous solutions). The developed protective coating has fungicidal properties, protecting structures from the appearance of blue stains, mold and wood-destroying fungi. Revealed a good correlation between the concentration of biocide and fungicidal coating properties. A comprehensive assessment showed that the developed epoxy coatings have increased biocorrosion-resistant properties and can be used as protective coatings for glued-laminated timber structures exposed to mold fungi, high temperatures and high humidity.

    Development and research of a label caseine adhesive for packaging the industrial and household products
    (PC Technology Center, 2020) Cherkashina, A. N.; Rassokha, A. M.; Ryshchenko, I.; Komarova, O.
    A new composition of the environmentally friendly water-based casein adhesive glue with the increased adhesion to the substrate (glass, polyethylene terephthalate, etc.) and the improved water resistance has been developed and explored. The glue is easily washed away when labeling products that are packaged in reusable containers, but, at the same time, possesses high adhesion to different surfaces. The optimal formulation for the developed glue adhesive composition based on casein has been determined with the help of the investigated properties. The effect of the amount of a modifying additive on the dynamic viscosity at different deformation rates, the stickiness of the adhesive composition, and the hydrogen ions index (pH) has been studied. Such technological properties of the glue adhesive composition were investigated as viscosity – 170 Pa∙s; pH – 7.21; the mass share of dry residue – 38.2 %; stickiness – 58.17 a.u.; working temperature – +20…+25 °С. The optimal technological parameters for using the glue have been defined: optimal viscosity, from 130 Pa∙s to 170 Pa∙s; temperature, 25 °C, and 35 °C, respectively. The adhesive strength between a paper label and glass is 4 points, polyethylene terephthalate – 3 points. The operation properties were assessed based on the resistance of the glue adhesive composition against changes in temperature and environmental conditions, humidity, and mechanical impact. The requirements for the glue adhesive have been stated that are to be taken into consideration in its operation: resistance against the condensed and icy water and the ability of the label to be removed from the surface of the container in a washing machine at a temperature of 70–80 °C. The glue adhesive composition was examined by a SAB Miller method to assess its quality during an ice water resistance test. A copy paper method was used to assess the label gluing quality. The requirements for the glue adhesive have been defined, which should be taken into consideration in its operation (the resistance against the condensed and icy water and the removal of a label in a washing machine at a temperature of 70–80 °C with the addition of NaOH or surface-active substances).
