Abstract

The invention relates to an easy-to-clean mildew-proof PP composite material and a preparation method thereof. The method includes: adding PP resin, silicate oligomer, a water absorbent, a compatilizer, a mildew-proof aid, a compatibilizing dispersant and an antioxidant into a high-speed mixer, mixing for 6-10min at the speed of 240-500r/min to form a premix, and putting the mixed premix into a main feed port of a double-screw extruder for granulation, and preparing the easy-to-clean mildew-proof PP composite material. The water contact angle of the prepared easy-to-clean mildew-proof PP composite material is 65-80 degrees, and the mildew-proof grade is 0 grade. According to the invention, the silicate ester oligomer is easy to decompose to generate a silanol group after encountering water, and the silanol group migrates to the surface of the polypropylene composite material to greatly improve the hydrophilicity of the surface of the material, so that dust on the surface of the material is easier to wash away under the action of water, and an easy-to-clean effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of PP composite materials, and relates to an easy-to-clean anti-mildew PP composite material and a preparation method thereof. Background technique [0002] Due to its non-toxicity, light weight, good chemical resistance, and excellent processing performance, polypropylene materials are gradually favored by the majority of automobiles, home appliances, smart homes, etc. Problems such as mold spots are generated, which limits its application in environments such as high humidity. [0003] At present, the research on the easy-to-clean and antibacterial and mildew-proof properties of polypropylene has been reported. Patent CN201710474610.9 discloses a high-performance antibacterial PP-PA6 composite material and its preparation method, using mica powder through polybutylacrylate (PBA) The grafting of PBA can form an organic coating layer of PBA on the surface of mica powder, which has a strong three-dimensional...
