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.展开更多
