Epoxy Composites Filled with Natural Calcium Carbonate. 2. Epoxy Composites Obtained in the Presence of Monomethacrylic Derivative of Epidian-6 Epoxy Resin

Abstract

On the basis of Epidian-6 epoxy resin and methacrylic acid a monomethacrylic derivative of Epidian-6 with free epoxy and methacrylic groups (MMADER) has been synthesized. The structure of MMADER was confirmed by IR spectroscopy. The thermal stability of MMADER has been established. The cross-linking of unfilled epoxy-oligomeric mixtures and mixtures filled with CaCO 3 has been studied in the presence of MMADER. By means of IR spectroscopy, the chemistry of the formation of mixtures based on Epidian-5, oligoesteracrylate TGM-3, MMADER and polyethylene polyamine has been established. Physico-mechanical characteristics of epoxy-oligomeric mixtures filled with CaCO 3 have been established.

Cold-Cured Bisphenolic Epoxy Adhesive Filled with Low Amounts of CaCO3: Effect of the Filler on the Durability to Aqueous Environments

“…Calcium carbonate (CaCO 3 ) is commonly added in different shapes (round particles, rods, platelets) to polymers as the inorganic filler possessing many favorable features, such as ease of being incorporated in macromolecular materials, low environmental impact and toxicity, wide availability, and cheapness. This low-cost filler in micrometric size is able to improve the characteristics of epoxy coatings and paints (i.e., hardness, scratch resistance, corrosion resistance, thermal stability, Young modulus), as well as the performance of epoxy-based adhesives and composites (i.e., tensile and flexural strengths, impact strength and toughness, wear resistance), to enhance the flashover voltage properties of epoxy intended for electrical applications [ 3 , 5 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

Influence of Polymer-Silicate Nucleator on the Structure and Properties of Polyamide 6

“…On the other hand, to reduce the cost of such products and to improve their operational characteristics it was necessary to study the mixtures with a filler. Earlier we have shown [16,19] that CaCO 3 may be successfully used. So, here we investigated the epoxy-oligomeric mixtures filled with CaCO 3 ( Table 8).…”

“…The possibility of using oligomers with different functional groups, as well as CaCO 3 to obtain products based on Epidian-5 has been described in [16,19]. Monoperoxy derivative [16] and monomethacrylic derivative [19] of Epidian-6 were used as oligomers. Monoperoxy derivative of Epidian-6 contains free epoxy and peroxy groups and monomethacrylic derivative of Epidian-6 contains free epoxy group and methacrylic fragment.…”

Synergistic Effect of BaCl2 on Corrosion Inhibition of Copper by Mentha Spicata Oil in 1M Nitric Acid: Gravimetric and Raman Spectroscopy Studies

“…They are widely used for the production of epoxy resins, epoxy composites, and bio-based epoxy thermosets. [1][2][3][4][5][6][7][8][9] Moreover, epoxides are key materials for fine chemical synthesis due to their ring-opening activity. [10][11][12][13][14][15][16][17][18] Nowadays, the catalytic cycloaddition of CO 2 to different epoxides attracts considerable attentions of researcher all over the world as an efficient way for cyclic carbonates production as well as one of the best possible strategy for carbon dioxide neutralization by its fixation and recycling.…”
