The utility model relates to a medical safety grade rubber product with sericin modified surface and a preparation method thereof, belonging to the technical field of the manufacture of rubber and latex products. The present invention discloses an sericin composition used for surface modification of rubber products and improving its medical safety, and is characterized in that: sericin, natural polysaccharide, biological protein, biological enzyme, organic acid and salt coexist in proportion. The invention also discloses a preparation method, which is characterized in that the composition of sericin coated on the surface of the rubber product; and / or the sericin composition is added to the vulcanization of natural rubber latex, sericin composition in rubber vulcanization due to its hydrophilicity to the surface of the rubber product transfer, and the formation of hydrophilic protective film, allergic protein the precipitation barrier and chemical additives in rubber products. The positive effect of the invention is that the latex protein is modified, and the rubber strength is not reached at the same time to achieve the goal of not inducing the allergic reaction of the protein. The waste silk sericin resource was developed to save the resource and protect the environment.
【技术实现步骤摘要】
本专利技术涉及橡胶、胶乳制品制作工艺及对其性能和工艺改进的
，确切地说是涉及由丝胶组合物改性表面性能的橡胶制品。本专利技术还涉及形成这种制品，尤其是形 成胶乳手套和安全套的在线方法。
技术介绍
天然胶乳(NRL)是一种可再生的天然高分子胶体体系，其主要成分为橡胶烃、水、 非胶物质。以NRL为原料的天然橡胶制品具有优异的综合性能和不可替代性，已广泛应用 于医疗卫生领域，如医用导管、泌尿收集装置、灌肠器顶、压脉器、血压计封套、输氧袋、医用 手套、检查手套和避孕套等。自上世纪以来，随着人们对预防艾滋病、肝炎等病毒感染的意 识不断加强，导致了天然橡胶尤其是天然橡胶手套和避孕套需求量的急剧上升。但是，自20 世纪80年代以来，有关天然橡胶导致人体过敏反应的报道频繁出现，其过敏原为NRL含有 的可溶性蛋白质，症状为接触天然橡胶后产生皮肤痒、发炎、起疙瘩、长水泡，严重时会引起 过敏性休克。早在1991年美国食品医药管理局(FDA)就已警告市民天然橡胶所含的蛋白质 可导致威胁生命的过敏性休克，同时把医用手套列为第2级器材管理；英国卫生部也把天 然橡胶增列为致敏物或健康有害...
【技术保护点】
具有丝胶改性表面的医用安全级橡胶制品，其特征是：在橡胶制品表面形成由丝胶组合物构成的分子保护层，所述的丝胶组合物是由丝胶蛋白或丝胶蛋白水解物、生物酶、表面活性剂、天然多糖、生物蛋白、有机酸和盐按比例组成。
