Problems solved by technology

[0002] The trunking currently in circulation in the market is basically produced by extrusion molding. The materials used are generally PVC or halogen flame-retardant ABS. These two materials have major environmental protection problems. If there are mandatory regulations, they will inevitably need to be eliminated. At the same time , the trunking in some special places also needs its material to have better temperature resistance

Embodiment 1

[0008] Embodiment 1 provides a special low-smoke halogen-free flame-retardant PCABS alloy material for trunking extrusion, which is composed of the following components by weight: polycarbonate: 72.0%, ABS resin: 10.0%; composite halogen-free flame retardant: 15%; smoke suppressant: 0.2%; antioxidant: 1.0%, lubricant: 0.3%; other additives: 1.5%.

[0009] First dry polycarbonate at 120 degrees for 4 hours, and ABS resin at 75 degrees for 2 hours, and then weigh it with antioxidants, compound halogen-free flame retardants, smoke suppressants, lubricants, and other additives in proportion Finally, mix in the mixer at low speed for 10 minutes. The mixer adopts low-speed mixing and is made of stainless steel. The gap between the mixing blade and the cylinder wall should be less than 0.5 cm. The mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, and there is no obvious lump block or agglomeration, a...

Abstract

The invention discloses a special low smoke zero halogen fire resistant polycarbonate / acrylonitrile-butadiene (PCABS) alloy material for slot extrusion. The alloy material comprises the following components by weight percent: 47.5-96% of polycarbonate, 3.0-50.0% of ABS resin, 1-35% of composite halogen-free fire retardant, 0-3.0% of smoke suppressant, 0.1-2.0% of antioxidant, 0.1-2.0% of lubricant and 1.3-5.5% of other additives. The alloy material provided by the invention has the following advantages: the comprehensive mechanical performance is good, the alloy material does not contain halogen, and the product has beautiful appearance and is convenient to produce and purchase; and all the requirements on environmental friendliness can be met and the product competitiveness can be increased comprehensively.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a special low-smoke, halogen-free, flame-retardant PCABS alloy material for wire slot extrusion. The invention also relates to a method for making the special low-smoke, halogen-free and flame-retardant PCABS alloy material for wire slot extrusion. Background technique [0002] The trunking currently in circulation in the market is basically produced by extrusion molding. The materials used are generally PVC or halogen flame-retardant ABS. These two materials have major environmental protection problems. If there are mandatory regulations, they will inevitably need to be eliminated. At the same time , The trunking in some special places also needs its material to have better temperature resistance. Contents of the invention [0003] The object of the present invention is to provide a low-smoke, halogen-free and flame-retardant PCABS alloy material with e...
