Description
Summary:To effectively screen pathogens or eliminate allergy symptoms caused by the protein in natural latex products, the strength of the natural latex film must be improved and the water‐soluble protein content in the latex products must be reduced. In this article, response surface methodology was used to optimize the reaction conditions for the preparation of hydroxyapatite (HA), and the reinforcement and adsorption of water‐soluble proteins on natural rubber latex (NRL) by HA modified by coupling agent KH550 were studied. Modified HA was homogenously dispersed in the NRL, and the tensile and tear strengths of the rubber film were increased by 37.45% and 40.86%, respectively. In addition, modified HA adsorbs the water‐soluble protein from the latex film. Compared with pure NR film, its protein content is reduced by 50.79%. This article has a reference value for the preparation of high‐performance natural latex film with low protein content.
