Abstract

The invention discloses a halogen-free flame-retardant POE (Polyolefin Elastomer) compound material and a preparation method thereof. The halogen-free flame-retardant POE compound material is prepared from the following components in parts by weight: 100 parts of POE resin, 70-140 parts of halogen-free compound retardant, 5-30 parts of modifier, 3-10 parts of lubricating dispersing agent and 0.1-0.6 parts of anti-oxidant. The preparation method comprises the following steps of: putting the POE resin, the halogen-free retardant, the modifying agent, the lubricating dispersing agent and the anti-oxidant into a high-speed mixing machine for mixing till the materials are heated to 65-75 DEG C through frication heat generated by mixing, discharging and cooling; and feeding a cooled mixed material into a double-screw extruder for melting and extruding, cooling an extruded bar stock with a water groove, and drawing into a granulating machine for granulating to obtain the halogen-free frame-retardant POE compound material. The elongation rate of the halogen-free flame-retardant POE compound material is over 600 percent, the oxygen index is over 30 percent, the liquidity of a melt is high, and the heat ageing resistance is high.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a halogen-free flame-retardant POE composite material and a preparation method thereof. Background technique [0002] POE resin is a new type of polyolefin elastomer polymerized by DOW Chemical Company of the United States with metallocene as a catalyst. Compared with other polyolefin elastomers, it has the advantages of low price and easy molding and processing. It is widely used in automobiles, electronic appliances, building seals, sports, etc. Equipment and polymer toughening modification and other fields. [0003] POE is a flammable material, and as its application continues to increase, it is imperative to modify it for flame retardancy. Traditional halogen-containing flame retardants have high flame retardant efficiency, but they produce deadly toxic fumes when burned. Contents of the invention [0004] One of the objectives of the presen...
