The paper examines methods and techniques for regulating the mechanical properties of polymer binders based on a mixture of chlorosulfonated polyethylene and epoxy oligomer. The effect of the ratio of components in the mixture and hardeners on the adhesive properties of films obtained from the solution to metal surfaces has been studied.
The paper studies the properties of mixtures of ABS-2020 + PA-6 with the content of one of the components 0, 5, 10, 20, 30, 50, 70, 80, 90, 95 and 100%. The ambiguous nature of the dependence of the melt flow index on the composition of the mixture at different test temperatures has been established. The tensile yield strength of injection-molded samples of mixtures varies almost additively to the composition. When the PA-6 content in the mixture is from 20 to 30%, phase reversal is noted.
The kinetics of changes in ionic viscosity and dielectric loss tangent during curing are considered using epoxy-containing binders as an example. Rheological properties of binders are studied. It is shown that the introduction of epoxyphosphazene into epoxy resin does not reduce the processability of the binder.
The paper presents the results of a study of the properties of adhesives based on an epoxy binder modified with cyclophosphazenes. The optimal amount of modifier has been selected which allows to increase the adhesive strength of the developed adhesives to metal substrates.
The effect of a compatibilizer – styrene-ethylene-butylene-styrene thermoplastic elastomer – on the compatibility of a mixture of recycled polystyrene and recycled polyethylene is studied to improve its physical and mechanical characteristics. It is shown that the introduction of 2.5 wt.% compatibilizer into the studied polymer blend (50/50 wt.%) improves its complex of physical, mechanical and technological properties.
A method has been developed that allows the creation of sandwich structural materials with an original structure based on a binary mixture of ultra-high molecular weight polyethylene and Vistamaxx ethylene-propylene copolymer, followed by the application of Evolam film and ultra-high molecular weight polyethylene fabric. The deformation and strength properties of polymer sandwich structural materials are investigated and it is shown that the developed advanced materials have improved frost resistance and can be processed using modern highly efficient methods.
This paper presents the results of a study of the effect of fillers on the properties of polyimide film materials. The physical, mechanical and operational properties of the modified composite material were investigated: strength, elongation at break and corona resistance. The morphology of the surface of modified polyamide films has been studied. fumed silica, kaolin and silica in different concentrations, as well as silica solution were used as modifiers of the studied materials.
The properties of polymer-polymer composite materials based on ultrahigh molecular weight polyethylene and ethylenepropylene copolymer Vistamaxx 6202 have been investigated. The structure of polymer-polymer materials based on ultrahigh molecular weight polyethylene has been studied. The possibility of obtaining a fundamentally new technological polymer material with a unique set of properties is shown.
The peculiarities of changes in the properties of polymer-bitumen binders under the influence of UV radiation are considered. The effect of butadiene-styrene copolymer and the duration of UV radiation on the stability of these binders is shown. It is shown that bitumen binders modified with butadiene-styrene copolymer are sensitive to UV radiation and require additional stabilization.
The rheological properties of various grades of acrylonitrile-butadiene-styrene plastic have been studied. It is shown that the ER400 grade has a higher thermal stability compared to other grades studied, as it is practically not subject to changes when exposed to temperature and mechanical loads. Composite materials based on a basalt fiber reinforced alloy of acrylonitrile butadiene styrene plastic with polycarbonate have been developed.
The physical and mechanical properties of a gradient polymer composite material obtained using polyepoxyisocyanurates as a binder and polyester batting as a filler. The presence of a gradient of properties within a single sample has been established, and the effect of the modifying additive sudan blue G on the performance characteristics of the composite under study has been determined.
The curing process of benzoxazine based on bisphenol A and aniline was studied using differential scanning calorimetry. Using the approach proposed by Vyazovkin, the dependences of the effective activation energy (Еα) on the degree of curing (α) were calculated in the MATLAB® working environment. The shape of the dependences of Еα on α revealed the complex character of the curing process.
The paper presents the results of a study of the gas permeability of polymer monofilms for helium, the dependence of the rate and coefficient of gas permeability on the thickness and chemical nature of the films, and the effect of surface spraying on the rate of gas permeability. Based on the data on the gas permeability of films, combined fabric-film materials for aeronautical engineering have been developed. The barrier and physical-mechanical properties of combined fabric-film materials have been studied.
A technique has been developed to study the effect of an electric field on the adhesive strength of polymer–fiber compounds. The designs of the necessary samples and the procedure of carrying out the process of their “hot” and “cold” curing in the presence of an electric field are proposed. Using the example of “steel fiber – epoxy binder filled with nanotubes” compounds, the high sensitivity of the developed method is shown.
Carbon fiber reinforced plastics based on epoxy binders modified with card type phthalide-containing polyarylene ether ketone have been developed. The materials obtained by wet winding have a shear strength of 40–45 MPa. Modification of the binder with thermoplastic leads to a 65% reduction in residual stresses in carbon fiber reinforced plastics. With an increase in the thermoplastic content in the binder, the modulus of elasticity of reinforced plastic decreases slightly.
To date, waste products from unplasticized polyvinyl chloride of all basic plastics are the least suitable for recycling due to various degradation processes occurring during recycling. The availability of waste polyvinyl chloride in the Russian Federation, as well as mechanical and technological properties of the main fraction of waste compositions of unplasticized polyvinyl chloride were studied in this work. It was found that the process of recycling of this polymer waste can be difficult without additional introduction of stabilizing chemical complex.
