Abstract

The invention relates to aluminum alloy section material heat insulation bar special enhancing plasticizing nylon 66 composite material and its preparing method. Its components part by weight as follows: nylon 66 resin 100, graft elastomer 5-15, glass fiber 0-40, inorganic filling 0-30, silane coupler 0.5-3, dispersion lubricant 0.5-4, compound antioxidant 0.3-3, graft polyethylene 3-10, and black agglomerate 3-5. The preparing method includes the following steps: batching, mixing, fusing, cross blend extruding granulating with 240-270 degree centigrade extruding temperature, packing. The enhancing plasticizing nylon 66 composite material has the advantages of high strength, luster, fluidity, low water absorption etc.

Description

1. Technical Field [0001] The invention relates to a reinforced and toughened nylon 66 composite material special for aluminum alloy profile heat insulation strips and a preparation method thereof. 2. Background technology [0002] At the end of the last century, my country comprehensively promoted double-layer aluminum alloy doors and windows in high-rise buildings to achieve the purpose of energy saving. Glass fiber reinforced nylon 66 profile is used as the thermal insulation connection material between the two layers of aluminum alloy windows. The glass fiber reinforced nylon 66 profile not only connects and fixes the windows on both sides, and at the same time, because the heat conduction of nylon is small, it plays a role in preventing the conduction of heat insulation. Domestically, glass fiber reinforced nylon 66 profile extrusion production technology has been introduced from abroad, and its raw materials are imported from Germany and other places. As aluminum alloy stee...
