Epoxy resin fiberglass
Thread Content
I would like to ask everyone, does anyone have relevant specifications and requirements for the material formula of FRP, such as how much epoxy resin and how much curing agent should be used for each square meter of epoxy resin FRP? How many Bingtong? How much powder? Thank you for this?
Regarding furan, X41 fiberglass materials are also available!
Epoxy resins commonly used in epoxy FRP include common bisphenol A types such as 681#, 6101#, and 634#, phenolic epoxy resin 644#, alicyclic epoxy 6207# and HY-201 polybutadiene epoxy resin. Commonly used curing agents in auxiliary materials are DTA, m-phenylenediamine, maleic anhydride, phthalic anhydride, and endomethine * * Phthalic anhydride, etc., the accelerator is triethanolamine. Recipe one: 6109# Epoxy Resin 100 Styrene 5 Triethanolamine 6 Triethylenetetramine 4 Room temperature for 10 days, plus 130℃ for 6h τ=13MPa δ=298.5MPa δCompression resistance=300MPa Formula 2: 644# Phenolic epoxidation 100 NA acid anhydride 68 Dimethylbenzylamine 1.8 Propylene 100 Room temperature - 120℃ (40min) - 200℃ (40 minutes) - Cooling - Mold removal treatment 150℃/2h + 260℃/1 day Formula 3: 634# Epoxy Resin 32 3193# Polyester 28 Phthalic Anhydride 8 BPO 2 Styrene 30 100. C/2h + 180. C/8h has good bending strength and rebound ability. The above parts are all weight ratios. As for the ratio to fiberglass fabric, it depends on the type of fiber fabric. Usually the surface felt glue content is more than 90%. The chopped strand felt glue content is 70%~80%. The gingham glue content is about 50%. The fiber roving glue content is 35%~45%. I currently mainly use vinyl resin and epoxy resin. I just understand it. I hope it can help.
The curing agent in the formula is directly related to the resin grade, and the ambient temperature also has an impact. Other materials are mainly related to the construction conditions. They must be easy to construct and suitable for use conditions after curing. You should be talking about epoxy resin that is liquid at ambient temperature. Before construction, prepare a sample to check the curing condition.
