摘要
通过将过期牛奶和天然色素混合,利用蛋白质的复杂变性和化学偶联作用,一步法制备生物质防水抗紫外颜料.借助简便的喷涂工艺可在棉机织物、罗布麻织物、丝绸、非织造布、纸板等各种基材表面快速形成兼具防水及抗紫外功能的颜料颗粒涂层,从而实现对废弃过期牛奶的高值化利用.该方法工艺简单、成本低、对环境友好,在纺织印染、精细化学品、建筑等领域具有较大的应用潜力.
Abstract
A one-step method is carried out for preparing a biobased waterproof and UV-resistant pigment by mixing expired milk with natural pigments,utilizing the complex denaturation of proteins and chemical coupling effects.With the aid of a simple spraying process,pigment particle coatings that possess both waterproof and UV-resistant functions can be rapidly formed on various substrates such as cotton woven fabrics,ramie fab-rics,silk,non-woven fabrics,and cardboard,therefore,high-value utilization of discarded expired milk can be realized.It features a simple process,low cost and environmental friendliness.It holds significant application potential in fields such as textile printing and dyeing,fine chemicals,and construction.
