Determination of glass transition temperature and irradiation resistance of elastomeric materials based on chlorinated natural rubber
(RAD Association, 2018-06-18)
Synthetic rubbers have different surface structures but benefit from chlorination. In many cases their tensile strength and extensibility is lower than natural rubber and for that reason more easily mechanically damaged. ...
Effect of silica on the properties of elastomeric materials based on NR/BR/SBR ternary rubber blend
(University of Banja Luka, Faculty of Technology, Banja Luka, 2018-11-02)
The effects of pyrogeneous silica on the mechanical properties of elastomeric
materials based on natural rubber (NR), polybutadiene rubber (PB) and styrene butadiene
rubber (SBR) are reported. For sample preparations the ...
The effect of UV-irradiation on the thermal stability of modified urea-formaldehyde resins with thermally activated montmorillonite
(RAD Centre, 2021-06-14)
The montmorillonite as a 2:1 smectite type clay has two tetrahedral sheets of silica sandwiching the alumina octahedral sheet. The particles of this mineral are plate-shaped with the thickness of 0.96 nm and an average ...
The influence of modification and the particle size of the montmorillonite on the hydrolytic stability of urea-formaldehyde composite
(Materials Research Society of Serbia, 2019-09-02)
Urea–formaldehyde (UF) resin adhesive is a polymeric condensation product of formaldehyde with urea and is considered as one of the most important wood adhesives. In spite of some advantages such as lower cost, fast curing, ...
The influence of the type of activation of the montmorillonite of hydrolytic stability of the urea-formaldehide nanocomposite
(University of Novi Sad, Faculty of Technology Novi Sad, 2019-10-10)
In this work the hydrolytic stability of nano-composites based on urea-formaldehyde resin (UF) and montmorillonite (K10) as formaldehyde scavenger was investigated. K10 was activated by sulfuric acid (H2SO4) with and without ...
The effect of UV irradiation on hydrolytic stability of urea-formaldehyde resins filled with thermally modified montmorillonite
(RAD Centre, Niš, Serbia, 2019-06-10)
The hydrolytic stability of organic-inorganic nano-composites prepared by a two-stage
polymerization of urea-formaldehyde resin (UF) filled with thermally activated montmorillonite (MMT) has been assessed before and after ...
Cross-linked bio/inorganically modified urea-formaldehyde resins: influence of γ-radiation on formaldehyde content
(2022-06-13)
The effect of γ–irradiation on hydrolytic stability of nano-silica, nano-titania, and wood flour (WF) modified urea-formaldehyde (UF) resins was investigated. Modified UF resin with wood flour (Pinus silvestris L.) as ...
Irradiation resistance of elastomeric composites based on NR/CSM blend and waste rubber powder
(RAD Centre, Niš, Serbia, 2021-06-14)
Effect of waste rubber particles (WTR) size on elastomers based on natural rubber and chlorosulfonated polyethylene rubber (NR/CSM= 50:50) was studied. Two types of WTR with different particle size (150–250 μm and 450–600μm) ...
INFLUENCE OF MODIFIED MONTMORILLONITES ON FORMALDEHYDE CONTENT IN UREA-FORMALDEHYDE/MONTMORILLONITE COMPOSITES
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)
The effect of different montmorillonites (KSF and K10) and their modifications (Na-KSF, Na-K10) on content of formaldehyde-FA (free and liberated) modified urea-formaldehyde (UF) composites was investigated. KSF and K10 ...
