Self-cleaning masterbatch and flame retardant high gloss polypropylene composite material special for intelligent closestools and preparation method

Abstract

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