Preparation and Properties Study of Anti-mildew and Flame Retardant Nylon Materials
The study selected four types of anti-mildew agents[silver ions,zinc oxide,polyhexamethylguanidine hydrochloride,and copper(Ⅱ)furanoxime complexes],and used a twin-screw extruder to prepare anti-mildew and flame-retardant nylon composites containing nitrogen,bromine,and phosphorus flame retardants,respectively.The study investigated the effects of different types of anti-mildew agents on the flame retardancy and mechanical properties of nylon,and studied the effects of different types of flame retardants on the anti-mildew properties of nylon composites.The results show that the types of anti-mildew agents has no obvious effect on the mechanical properties and flame retardancy of nylon,but has a negative impact on the flame retardancy.Copper(Ⅱ)furanoxime complexes or polyhexamethylguanidine hydrochloride at 0.5%mass fraction can provide good mildew protection,the relevant nylon composite has a mildew protection grade of 0,and the flame-retardant nylon with the same proportion of commercial silver ion or zinc oxide antibacterial agent has only a mildew protection grade of 1.Adding the same content of anti-mildew agent,the nylon composite containing bromine flame retardant and phosphorus flame retardant can reach grade 0,the nylon composite with MCA flame retardant system has the worst anti-mildew properties,and the anti-mildew grade is only grade 3.
