摘　　要：Nano SiO_ 2 modified natural rubber latex treated by ultrasonic and special dispersing agent was used to prepare medical gloves, and the mechanical and aging properties of the product were investigated. The results show that the tensile strength of the glove with 0.5%(mass fraction) nano SiO_ 2 was 20.2 MPa when the contrast was 15.9 MPa. After 2%(mass fraction) nano SiO_ 2 was filled in the latex, the tensile strength of the product increased to 25.5 MPa. With the increase of the nano SiO_ 2 content, strength at 300% and 500% elongation of the products increased gradually. Addition of nano SiO_ 2 particles didn′t change the elongation at break and elasticity of the glove. After 33 hours aging in hot air at 100 ℃, the tensile strength of the glove with 2%(mass fraction) nano SiO_ 2 was as high as 12.7 MPa.Nano SiO_ 2 modified natural rubber latex treated by ultrasonic and special dispersing agent was used to prepare medical gloves, and the mechanical and aging properties of the product were investigated.
