Analysis and application of a modified high elastic nylon pressure ulcer seat cushion
Aiming at the problem of poor toughness of traditional nylon materials,a modified high elastic nylon ma-terial was proposed for preparation,and this material was used as the raw material to make elderly pressure ulcer seat cushions to prevent the occurrence of elderly pressure ulcers.The experimental results showed that the compati-bilizer made under the condition of thermoplastic elastomer ethylene-octene copolymer(POE)∶graphene oxide(GO)=1∶0.6 using tetraethylenepentamine(TEPAF)with molecular weight 931 as raw material could make MA-POE disperse well in the nylon matrix without obvious volume separation.At this time,the flexural strength,com-pressive strength and tensile strength of the modified high-elastic nylon were 117,124 and 88 MPa,respectively,and the toughness was significantly improved.The pressure ulcer cushion made of modified high-elastic nylon has certain application value in reducing the incidence of pressure ulcers in the nursing of the critically ill elderly.
