Cellulose thermoplastic material and preparation method thereof

一种纤维素热塑材料及其制备方法

Abstract

本发明公开了一种纤维素热塑材料及其制备方法,该热塑材料由离子液体和纤维素构成,其中,离子液体与纤维素的质量比为20/80~50/50,所述离子液体作为增塑剂,能够破坏纤维素分子间氢键和增加自由体积,以实现对纤维素的塑化。制备是通过预混、混炼、热机械加工成型和浸渍后烘焙得到。这种纤维素热塑材料不仅具有可反复成型加工的特点,而且抗增塑剂迁移、结构稳定。本发明提供的纤维素热塑材料的制备方法与现有技术相比,具有工艺简单、生产效率高、产品可二次加工的特点,改善了以往纤维素材料形式单一的缺陷,拓宽了纤维素材料的应用领域。
The invention discloses a cellulose thermoplastic material and a preparation method thereof. The thermoplastic material consists of ionic liquid and cellulose, wherein a mass ratio of the ionic liquid to cellulose is 20/80-50/50, and the ionic liquid serves as a plasticizer and can break hydrogen bonds among cellulose molecules and increase the free volume, so that cellulose plasticization is realized. The preparation method comprises the following steps: premixing, mixing, performing thermal machining and molding, impregnating and roasting. The cellulose thermoplastic material can be repeatedly molded and processed and is resistant to plasticizer migration and stable in structure. Compared with the prior art, the method for preparing the cellulose thermoplastic material, provided by the invention, has the characteristics of simple process and high production efficiency; the product can be subjected to secondary processing, the defect that the conventional cellulose material is single in form is overcome, and the application field of the cellulose material is widened.
