Abstract

The invention provides a high-gloss flame-retarded polypropylene composite, comprising the following components by weight: 60-89.2% of polypropylene, 2-10% of linear low density polyethylene, 2-10% of compatilizer, 2-10% of brightener, 0.2-0.6% of antioxidant, 0.4-0.8% of lubricant and 4-9% of flame retardant, wherein the flame retardant comprises 0.2-0.6% of bisphenol A-di (diphenyl phosphate). The invention further provides a preparation method of the high-gloss flame-retarded polypropylene composite. The high-gloss flame-retarded polypropylene composite has high gloss and flame resistance, and the preparation method of the composite is featured with simple technology, conveniently operation, high benefit and low cost, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-gloss flame-retardant polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is non-toxic, odorless, low density, has good electrical properties and high-frequency insulation properties, is less affected by humidity, and common acid and alkali organic solvents basically have no effect on it, and has good environmental adaptability and durability. There are many types of polypropylene modified materials, such as glass fiber reinforced, mineral reinforced, flame retardant, transparent, high gloss, etc., the market demand is huge, and the consumption is huge. [0003] At present, both high-gloss polypropylene and flame-retardant polypropylene have mature products circulating in the market, but both have obvious advantages and disadvantages. Generally, it is difficult to balance flame-retardant and h...
