preparation example Construction

[0030] In addition, the present invention also provides a method for preparing a flame-retardant polypropylene composite material, comprising the following steps:

[0031] Take each raw material component by weight parts as follows:

[0032]

[0033] First, fully mix polypropylene resin, white oil, toughener and compatibilizer, then add decabromodiphenylethane, inorganic flame retardant, flame retardant synergist, antioxidant, anti-dripping agent and UV The light absorbing agent is uniformly mixed, extruded by a screw extruder, drawn into strands, cooled and granulated to obtain a polypropylene composite material, wherein the temperature range of the extruder is between 175°C and 210°C.

[0034] The polypropylene composite material is produced by mixing polypropylene resin, toughener, compatibilizer, decabromodiphenylethane, inorganic flame retardant and flame retardant synergist with corresponding additives through a screw extruder under high temperature and high shear. T...

Abstract

The invention relates to a flame retardant polypropylene composite material and its preparation method. The retardant polypropylene composite material comprises the following components by weight: 35-45 parts of polypropylene resin, 15-17 parts of decabromodiphenylethane, 28-35 parts of inorganic fire retardant, 6 parts of flame retardant synergistic agent, 5-10 parts of flexibilizer and auxiliary agent. The flame retardant polypropylene composite material has excellent comprehensive properties, especially the flame retardant performance can reach a V-0 grade in UL-94 which accords with the flame retardant requirement, the material is environment-friendly and accords with the requirement of environmental protection, so that the flame retardant polypropylene composite material enables widepopularization and application. In addition, the invention also relates to a method for preparing the flame retardant polypropylene composite material.

Description

【Technical field】 [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant polypropylene composite material and a preparation method thereof. 【Background technique】 [0002] Polypropylene composite materials have excellent processing performance, mechanical properties, chemical corrosion resistance and other characteristics, occupy an important position in plastics, and can be widely used in the field of communication box production. With the development of science and technology, people have more and more strict requirements on the fire and flame retardancy of polypropylene composite materials, and at the same time, the requirements on environmental protection are also getting higher and higher. The flame retardants in most traditional polypropylene composite materials will produce carcinogenic and other toxic substances when they decompose, which limits the application of composite materials. 【Content of invention】 [0003] Base...
