Clean synthesis of epoxy plasticizer with quaternary ammonium
Conventional methods for preparing epoxy plasticizers produces a large amount of waste water. Furthermore, cardanol (a byproduct of cashew nut processing) has the potential to be an economic alternative for producing fine chemical products.
Highly Efficient Plasticizers-Antipirenes for Epoxy Polymers
Abstract —The possibility of using oligo (resorcinophenyl phosphate) with terminal phenyl groups (Fylolflex) and trichloropropyl phosphate as effective plasticizers for epoxy polymers has been investigated.
CN101914219A - Preparation method of composite epoxy plasticizer
The invention relates to a preparation method of a composite epoxy plasticizer. The composite epoxy plasticizer is prepared by mixing raw materials of fatty acid methyl ester and soybean oil through one-step epoxidation reaction, wherein the fatty acid methyl ester accounts for 25-90% by mass, hydrogen peroxide is used as an oxygen supplier and accounts for 25-35% of the raw material by mass
Preparation method of epoxy resin composite material
The invention relates to a preparation method of an epoxy resin composite material. The preparation method comprises the following steps: uniformly mixing epoxy resin, a curing agent, an accelerant and a diluting agent according to a certain ratio; de-foaming in vacuum and pouring into a standard test sample mold; curing in a drying oven; winding 16 bundles of T300 carbon fibers on a wire rack
Synthesis and characterization of PVA/Starch/CMC composite films
Polyvinyl alcohol/Starch/Carboxymethyl cellulose (PSC) composite films were synthesized by solvent casting method using glycerol as plasticizer and citric acid as cross linking agent. The effect of different loadings of carboxymethyl cellulose (CMC) on thermal and tensile properties of PVA/Starch (PS) composites was investigated.
