Abstract:

Epoxy resins are commonly used to manufacture the molding compounds, reinforced plastics, coatings, or adhesives required in various industries. However, the demand for new epoxy resins has increased to satisfy diverse industrial requirements such as enhanced mechanical properties, thermal stability, or electrical properties. Therefore, in this study, we synthesized new epoxy resin (PPME) by modifying phosphorous-containing polyol. The prepared resin was analyzed and added to epoxy compositions in various quantities. The compositions were cured at high temperatures to obtain plastics to furthe

Abstract:

Epoxy compositions are wide-spread in repairing the ship propellers blades damaged under cavitation attack. Most of the epoxy repair compositions contain the metal powders as filler. But the manufacturers of such compositions do not substantiate the expediency of using the metal powder in epoxy compositions for repairing the blades with cavitation wear spots. And the issue of the influence of metal powder filler on the cavitation wear resistance of the epoxy composition remains open.

The chemical and atmospheric resistance of epoxy films filled with wollastonite is on average 0.2 – 0.3% lower than that of the base composition, which is probably due to the porosity of both synthetic and natural wollastonite.

Abstract:

The process of forming epoxy powder compositions with the participation of highly dispersed magnesium oxide in the preparation of compositions by extrusion mixing of components in the melt is investigated. It is established that highly dispersed MgO particles participate in the polymerization process and act as additional crosslinking units of defective regions of the polymer network, which improves the functional properties of epoxy powder compositions. Coatings based on modified compositions are characterized by high physicomechanical properties at low temperature curing (130 °С) and can be

Abstract The main focus of the paper is to study the effect of fibre reinforcement on compressive strength and compressive modulus of epoxy granite. To investigate the effect of fibre reinforcement, two compositions were considered likes 20% Epoxy and 80% Granite without fibre reinforcement and 20% Epoxy, 75% Granite and 5% fibre reinforcement. Based on the literature studied, three types of fibre were considered viz. steel fibre, carbon fibre and basalt fibre. Three specimens of each type of fibre i.e. nine specimens and three specimens without fibre reinforcement were prepared. The obtained

A method has been developed for producing an epoxy composition based on a low-viscosity epoxy-resorcinol resin, a phosphazene-containing curing agent, isophoronediamine, and thermally expanded graphite as a filler. The degree of cure and the absence of side reactions during the curing process were confirmed using IR spectroscopy. The influence of the content of phosphazene-containing curing agent and filler on the physico-mechanical properties of the composition, its fire resistance, and antistatic properties were studied.

Parameters such as the curing process, glass transition of epoxynanocomposites, structure and morphology of CNT felt, initial epoxy composition, and epoxy nanocomposites were investigated. The influence of CNT felt on curing process in epoxy nanocomposites with different amounts of curing agent was determined. An exothermic reaction between the curing agent and the surface of CNTs was established.

The possibility of processing lignosulfonates to obtain composite materials using ED-20 epoxy resin as a binder was considered. It was shown that powdered lignosulfonates (PLS) play the role of a hardener for epoxy resins and reduce the toxicity of polyethylenepolyamine (PEPA), which is widely used as an industrial hardener, by 50–68 %. The article assesses the possibility of using PLC as a hardener and filler composition. The optimal composition of lignoepoxy compounds was revealed: ED-20 – 60–70 % by weight; PLS – 30–40 % by weight; PEPA – 6–7 % by weight. Biotesting proved that the resultin

Specifically, it focuses on nitrogen-containing derivatives of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, phosphinates, phosphorus–nitrogen salts, and aryloxycyclophosphazenes. The findings indicate that these classes of fire retardants enhance the limiting oxygen index, decrease heat and smoke emission indices in epoxy compositions, and facilitate the creation of self-extinguishing materials.
