High strength and flame retardant, used for surface decoration and protection required flame retardant.
surface decoration and protection products required flame retardant
Flame retardant unsaturated polyester resin was used as the research object, and different accelerator and initiator systems, different concentrations and ratios were selected at appropriate temperatures.The system of initiator and initiator with methyl ethyl ketone peroxide as initiator and cobalt octanate as promoter has been obtained.The dosage of accelerant and initiator was 1.2% and 2.0%, respectively.The higher the content of flame retardant, the better the flame retardant effect.However, the addition of flame retardant greatly affects the curing time of flame retardant UPR products.When the phosphorus content is 3.5%, the resin curing temperature 32 ℃, time of 10 h.The oxygen index (LOI) of the resin spline was 26.9.Adding DMMP to the resin so that the phosphorus content of the flame retardant coat resin reaches 5%, its LOI>28
