Fengcheng Ruixing Carbon Products Co., Ltd
Graphite Powder is a good composite materials and modified materials, Graphite powder can be used in epoxy vinyl ester resin, graphite powder effect on the properties of epoxy vinyl ester resin is some, because the graphite powder has good lubricity, electrical conductivity, high temperature resistance, corrosion resistance and so on, the graphite powder is a powder, its particle size is very uniform, used in epoxy vinyl ester resin, want to choose good dispersibility, high carbon content, small particle size of graphite powder.
Graphite powder of high carbon content, the conductive performance is good, its good dispersibility, will reduce the reunion phenomenon, its particle size is small, can play to lubrication and wear resistance of graphite powder, graphite powder used in epoxy vinyl ester resin production, through to the liquid viscosity and curing properties of the resin, resin casting body mechanics performance, thermal performance, performance and flame retardant performance test to study the graphite powder additives on the properties of epoxy vinyl ester resin.
Graphite powder adding quantity how much direct effect on the properties of epoxy vinyl ester resin, the results show that the addition of graphite powder of epoxy vinyl ester resin has obvious thickening effect, effect on curing of the resin had obvious polymerization, extended the gel and curing of the resin, reduce the resin curing exothermic peak, and makes the resin casting the decrease of strength of tensile strength and bending strength, modulus increases, basic have no effect on the thermal deformation temperature of resin. Graphite powder of the conductive properties of the resin to increase when the graphite powder more than 10% when the mass fraction of the resin resistivity reduce rapidly, when the mass fraction of 15% ~ 15% graphite resin surface resistivity decreased to 107 ~ 109 Ω, the addition of graphite powder flame retardant properties of the resin is reduced.
