Abstract

The invention provides a hydrophilic polypropylene mixture. The mixture is prepared from homo-polypropylene, talcum powder and hydrophilic agents, wherein the hydrophilic agents are selected from one or more of polyoxyethylene and polyvinyl pyrrolidone. The hydrophilic polypropylene mixture has the beneficial effects that the polarity is rapidly improved by the prepared polypropylene plates, and the contact angles of the polypropylene plates are reduced from 80 degrees to 20 degrees.

Description

technical field [0001] The invention relates to the field of polypropylene plates and provides a formula for realizing hydrophilicity of polypropylene plates. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene. According to the position of the methyl group, it is divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90g / cm 3 , is currently one of the lightest varieties of all plastics. Polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties. At the same time, polypropylene has good chemical resistance and is a very good environmental protection material. The processability of polypropylene is also excellent, and injection molding or extrusion molding are very easy to realize. [0003] However, due to t...
