A special self-cleaning masterbatch for smart toilets and flame-retardant high-gloss polypropylene composite material and preparation method

Abstract

The invention relates to the technical field of polypropylene material modification, in particular to a special self-cleaning masterbatch for intelligent toilets, a flame-retardant high-gloss polypropylene composite material and a preparation method. The composite material comprises the following raw materials by weight: 50-78.6 parts of polypropylene; 3-10 parts of flame retardant; 10-20 parts of self-cleaning masterbatch; 0.1-0.5 parts of nucleating agent; 0.1-0.6 parts of antioxidant; 10-20 parts of barium sulfate; 0.2-0.9 parts of other additives. The special flame-retardant high-gloss polypropylene composite material for intelligent toilet prepared by the present invention can overcome the deficiencies of flammability, self-cleaning difficulty and high price in the prior art by cooperating with self-cleaning masterbatch, and is suitable for intelligent toilet seat The use of such product materials has important practical application value.

Description

technical field [0001] The invention relates to the technical field of polypropylene material modification, in particular to a special self-cleaning masterbatch for intelligent toilets, a flame-retardant high-gloss polypropylene composite material and a preparation method. Background technique [0002] With the acceleration of the pace of modern life and the increase of consumer demand, toilet and bathroom products are gradually becoming intelligent; at present, intelligent toilets have functions such as heating, lighting, and cleaning, so there are special requirements for intelligent toilet materials, especially its seat Components are required to use materials with flame retardant, self-cleaning, and high-gloss properties. At present, polypropylene materials are commonly used. However, the general polypropylene plastic oxygen index is only about 18%, which is a flammable material; the contact angle is only about 90°, and it is difficult to self-clean, so it is difficult t...

Problems solved by technology

However, the oxygen index of general polypropylene plastic is only about 18%, which is a flammable material; the contact angle is only about 90°, and it is difficult to self-clean, so it is difficult to meet the needs of smart toilet materials.

[0003] Patent CN 106750976 A discloses a high-gloss, anti-scratch, easy-to-clean polypropylene material and its preparation method, mainly by adding fluorine-containing functional masterbatch and ultra-high molecular weight polydimethylsiloxane to improve the polypropylene material. Self-cleaning performance, but because the fluorine-containing functional masterbatch is expensive and contains thermoplastic polytetrafluoroethylene, it has a low ignition conflict with the flame-retardant grade V2, which affects the flame-retardant performance of flame-retardant polypropylene.
