| 摘 要： | 利用丝胶优良的抗氧化性和亲肤性等特点,将丝胶包覆在天然乳胶粒表面,从而隔绝了天然乳胶膜与皮肤的直接接触,改善天然乳胶制品对皮肤的过敏性反应,使其不仅具有耐氧化性,而且与皮肤接触后可有效防止肌肤干燥,抑制肌肤黑色素生成等。同时将水性聚氨酯通过先接枝后杂凝聚的方法,在不改变乳胶断裂伸长率的情况下,提高拉伸强度,实现了对天然乳胶过敏性和机械性能的双重改善。

| Abstract: | By the use of excellent oxidation resistance and skin friendly of silk sericin,silk sericin coats the surface of natural rubber latex particles which could cut off the direct contact with the skin and improve allergy.It makes natural latex rubber could not only resist oxidation but also effectively avoid skin drying and prevent melanin's generating.After heterocoagulating with aqueous polyurethane grafting with silk sericin,natural rubber latex membrane could improve fracture strength without reducing its b... |
