| Title of the article | Masterbatches for strengthening building materials based on urea-formaldehyde resins |
| Abstract. | The goal was to develop a recipe and technology of masterbatches to create a highly effective building materials based on urea-formaldehyde resins. The main attention was paid to the choice of modifiers, including the nanoscale, and fillers of different nature which are a part of masterbatches. The conditions of combining urea-formaldehyde resins developed by masterbatches, by encouraging various kinds of mixing and grinding of components (ultrasound and vibrokavitatsion). The complex of technological, operational and technical properties of wood-plastic composites and insulation materials (urea foam) based on urea-formaldehyde resins modified developed by masterbatches. The usage of a masterbatch technology makes it possible to adjust the parameters of the production of urea-formaldehyde foam and the formation of urea-formaldehyde foam structure, and as a result, the operating and technical properties of urea-formaldehyde foam. The studies are designed masterbatch formulations for particle characterized by a high complex operational and technical performance. Application of the developed masterbatches can reduce the compression and increase the viability of the binder to 3,2 months. Designed for the production of masterbatches formulations produces chipboard panels with higher flexural strength (65 % more of normalized parameters) and a lower content of free formaldehyde (2,3 times less). A decrease in water absorption by 63 %. The main advantage of using the developed masterbatches in comparison with existing modifier is a low cost, they can be used without changing the production technology and the reduction of the press time, ie increasing the productivity of the enterprise. The decrease in formaldehyde emissions while improving operational and technical properties increases the competitiveness of the market wood panels. |
