Abstract

The invention provides a high gloss flame retardant anti-bacterial and weatherproof polypropylene composite material and a preparation method thereof. The high gloss flame retardant anti-bacterial andweatherproof polypropylene composite material is composed of the following components by weight: 82-88 parts of P resin, 12-15 parts of an environment-friendly flame retardant, 0-1.5 parts of a flameretardant synergist, 0.3-0.6 part of an antibacterial agent, 0.3-0.5 part of a weather resistant agent, 0.2-0.4 part of an antioxidant, 0.5-1 part of a dispersant, 0.1 part of a fluoropolymer processing aid, and 1-2 parts of toner. The high gloss flame retardant anti-bacterial and weatherproof polypropylene composite material prepared by the method provided by the invention has gloss (at an angleof 60 degrees) up to more than 85, the flame retardant grade UL-94 up to V-0, an antibacterial rate up to 99% or more, xenon lamp 200h weathering test deltaE of less than or equal to 1.5. The material meets the provisions of the EU ROHS and REACH regulations, and the antibacterial agent accords with the relevant standards of Japan SIAA. The material can be used for intelligent closestool parts, and can effectively prevent fire hazards caused by ignition of electrical contact parts in closestools and the like. Closestools with SIAA logo can effectively inhibit the generation of bacteria and make people's life healthier.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a high-light flame-retardant, antibacterial, and weather-resistant polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene, usually a translucent, colorless solid, odorless and non-toxic. With excellent physical properties and good chemical stability, it is one of the most widely used general-purpose plastics. However, due to the extremely low oxygen index of polypropylene, only 17-18, it is a flammable material, and a large number of molten droplets are produced during the combustion process, resulting in flame propagation, which limits its application in many fields such as electronics, electrical appliances, transportation, and decorative materials. application. [0003] In order to broaden the application field of polypropylene material and make it ap...
