Creation of Teflex Biocidal Preparations from the Synthesis of a New Polymer to the Product Line. Part 1. Development of technology for producing biocidal preparations "Teflex"

Abstract

The article provides an overview of domestic and foreign literature on biodeterioration in buildings and structures, methods of bioprotection of materials and products, and research results on the technology for producing a biocidal preparation based on guanidine compounds. It is shown that damage to building materials caused by the multiplication of bacteria and mycelial fungi on them represents a serious danger both to the structures of buildings and to human health. One of the most effective ways to protect building materials and structures from damage by microorganisms is the use of biocidal compounds. Non-toxic biocidal preparations that meet modern requirements include polymers and oligomers of natural or synthetic origin. Among a wide range of polymer biocides, a group of compounds containing a guanidine moiety (PHMG) is distinguished. The results of a study of the authors on the technology for producing modified preparations of PHMG are presented. An increase in the biocidal effect was revealed during their modification with acid additives. The complexing ability of PHMG macromolecules with iron chloride has been established. The results of studies to reduce the toxicity of PHMG by removing ammonia during heat treatment are presented. As a result; we obtained biocidal compositions with a wide range of properties suitable for producing biocidal composite building materials reducing the contamination of microorganisms in rooms, devices, apparatuses, products, structures. The list of Teflex biocidal preparations produced by the developed technologies is given.
