Abstract

The invention relates to the technical field of high polymer materials, in particular to a high-impact-resistance halogen-free flame-retardant polypropylene composite material and a preparation method thereof. The high-impact-resistance halogen-free flame-retardant polypropylene composite material is prepared from the following components in parts by weight: 100 parts of polypropylene, 20-30 parts of a nano material, 20-30 parts of an impact modifier, 1-5 parts of silane coupling agent modified nano silica sol and 20-30 parts of a halogen-free flame retardant. The polypropylene composite material provided by the invention not only has high impact resistance and halogen-free flame retardance, but also has a better damping effect, and can play a good role in shock absorption and noise reduction.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high impact resistance halogen-free flame retardant polypropylene composite material and a preparation method. Background technique [0002] Polypropylene is a polymer obtained by addition polymerization of propylene. It is a white waxy material, with a transparent and light appearance, and a density of 0.89 to 0.91 g / cm. 3 , flammable, melting point 165 ℃, softening at about 155 ℃, the operating temperature range is -30 ~ 140 ℃, below 80 ℃, it can resist the corrosion of acid, alkali, salt and various organic solvents, and can decompose under high temperature and oxidation . [0003] Polypropylene Since the Italian Montecatini Company took the lead in realizing industrialization in 1957, the output of polypropylene has developed rapidly, and it has become one of the products with the fastest growth rate and the most active development of new varieties among the five...
