Description
Technical Field
The invention belongs to the field of high polymer materials, and particularly relates to a polypropylene hydrophobic material, and a preparation method and application thereof.
Background
The hydrophobicity of the solid material is the special wettability of the solid material to liquid, generally means that water drops are spherical on the surface of the solid, the contact angle is larger than 120 degrees, and the rolling angle is smaller than 10 degrees. Because the water drops can take away the pollutants when rolling off on the surface of the hydrophobic material, the surface of the material is kept clean. Therefore, the hydrophobic material has multiple characteristics of water resistance, corrosion resistance, ice resistance, adhesion resistance and the like. The composition and structure of the hydrophobic material are researched by various scholars through methods such as a wet chemical method, plasma irradiation, a sol-gel method, a layer-by-layer self-assembly method, an etching method, a chemical vapor deposition method, a physical vapor deposition method, a hydrothermal method, a template method and the like.
Polypropylene (PP) is one of five general-purpose resins, and has been widely used in the fields of packaging production, home appliance manufacturing, daily necessities, etc. due to its good processability and high bending and tensile strengths. The research and preparation of hydrophobic polypropylene are an important aspect of the polypropylene functional modification. The coating method and the surface treatment method are common methods for preparing the polypropylene material with highly hydrophobic surface, but the methods have various defects, such as complex process, harsh modification conditions and the like; solution coating modification, most of solvents are toxic reagents which are harmful to human bodies, and the produced wastewater is easy to cause environmental pollution; the reagent used for coating is expensive, and the production cost is higher, so the requirement of industrialized mass production cannot be met; the surface treatment method is to etch a micro-nano rough structure on the surface of the polypropylene material and graft a long-chain polymer with low surface energy, and although the contact angle of the prepared sheet is very high and even super-hydrophobic, the process is complex and limits the development of the sheet.

Comparing the test results of inventive example 1 and comparative example 1, it can be seen that: as can be seen from the SEM image of the surface of the injection molded article at room temperature, in comparative example 1, the low surface energy substance is dispersed in the matrix PP resin in a sea-island structure on the surface of the injection molded article, and the dispersion concentration and the dispersion specific surface area of the low surface energy substance in the interface layer are small, so that the low surface energy substance resists the wetting of water only in the independently dispersed spot positions when the water is wetted to the surface of the injection molded article, and the water can still be wetted to the surface of the injection molded article in other positions where the low surface energy substance is not present; in example 1, the low surface energy substance and the matrix PP resin are dispersed on the surface of the injection molded article in a bicontinuous phase structure, and the low surface energy substance is in a dendritic dispersion structure under the action of mechanical shear force in the twin-screw blending/injection molding process, which has the greatest beneficial effect that the low surface energy substance can be present on the surface of the injection molded article in a continuous structure, so that the dispersion concentration and the dispersion specific surface area of the low surface energy substance in the interface layer of the injection molded article can be further improved, and therefore, when water is infiltrated on the surface of the injection molded article, the action area of the low surface energy substance against the infiltration of the water is larger; meanwhile, the dendritic dispersion structure of the low surface energy substance can form a micro/nano structure on a three-dimensional space on the interface layer, so that the hydrophobicity of the injection molding product can be further improved. Meanwhile, if the surface of the injection molding product is further subjected to plasma sputtering treatment, the micro/nano structure on the three-dimensional space of the surface of the injection molding product can be optimized; when the surface of the injection molding product is soaked by water, the capability of resisting the soaking of the water on the surface of the injection molding product can be further improved, so that the hydrophobic effect of the injection molding product is further enhanced.
