[0036] The embodiment of the present invention, comparative example provides a kind of PP / PVDF alloy material, and its raw material composition, by mass fraction, specifically as shown in table 1, table 2:

[0037] Table 1

[0038]

[0039] Table 2

[0040]

[0041]

[0042] The antioxidant described in the above table is a compound composed of a hindered phenolic antioxidant and a phosphite antioxidant in a mass ratio of 1:1; in the embodiments of the present invention, the hindered phenolic antioxidant is further preferably As the antioxidant 1010, the phosphite antioxidant is more preferably the antioxidant 168. The lubricant is at least one of EBS, PETS and TAF. The barium sulfate is preferably nanoscale precipitated barium sulfate. The polypropylene resin (PP) is a composite of homopolypropylene and copolymerized polypropylene, preferably mixed with polyvinylidene fluoride resin at a mass ratio of (3-5):1.

[0043]Among them, the melt flow rate of polypropyle...

Abstract

The invention provides a PP / PVDF alloy material. The PP / PVDF alloy material is prepared from the following raw materials in mass percent: 67-95% of polypropylene resin, 3-20% of polyvinylidene fluoride resin, 8-17% of barium sulfate, 2-10% of oil additives, 0.1-0.6% of antioxidant and 0.3-0.7% of lubricating agent. By virtue of synergetic cooperation of the components, on the premise of ensuring the mechanical properties of the material, the material simultaneously has a high oil and water contact angle and a very low oil and water roll angle, so that the material has the characteristics of being capable of preventing oil stains, easy to clean and hydrophobic and oleophobic; and water and oil stains on the surface of the material easily slip off from the surface of the material, so that the part prepared from the material is capable of preventing oil stains and keeping cleanness in the kitchen environment and is easy to clean.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a PP / PVDF alloy material and a preparation method thereof. Background technique [0002] Polypropylene (PP) has the advantages of non-toxicity, low odor, low cost, chemical corrosion resistance, good mechanical properties, etc. It has a very wide range of applications in the fields of home appliances, sanitary ware, and electronics. For example, polypropylene modified materials are used in electric pressure cooker casings, rice cooker casings, etc. However, because it is in the kitchen environment, kitchen appliances made of polypropylene will inevitably have water or oil sticking to the surface of the material. Long-term storage will cause serious stains on the surface of the material, which greatly reduces the user experience of consumers. Therefore, improving the hydrophobic and oleophobic properties of polypropylene materials has important practical significance in the field o...
