Self-isolation fireproof flame-retardant PC and PBT composite material

Abstract

The invention relates to a refractory material and belongs to the field of organic refractory material processing. The self-isolation fireproof flame-retardant PC and PBT composite material comprises PC and PBT alloy structure layers and self-isolation flame-retardant layers which are alternately arranged; the PC and PBT alloy structure layer takes a PC and PBT alloy fiber textile layer as a main body structure; the self-isolation flame-retardant layer is made of a thermal decomposition expansion material; the thermal decomposition expansion temperature of the self-isolation flame-retardant layer is 5-30 DEG C higher than the structural instability temperature of the PC and PBT alloy fiber textile layer. When the material is heated, the self-isolation flame-retardant layer is thermally decomposed and expanded to form a thermal insulation layer with an inorganic flame-retardant material as a core, so the internal structure of the material is prevented from being further thermally damaged. And the addition amount of the self-isolation flame-retardant layer is extremely small, and the addition of the refractory material does not influence the change of the structural components of the PC and PBT alloy, and does not influence the structural strength, decomposition resistance and corrosion resistance of the PC and PBT alloy material.

Description

Technical field [0001] The present invention relates to a refractory material and a processing method thereof, and more particularly to a self-isolated refractory flame retardant PC, a PBT composite. Background technique [0002] The advantage of the PC is that the room temperature is high and tough, but the heat deformation is severe, the stress crack is high; the advantage of the PBT is that its rigidity is not affected by temperature, deformation, but the toughness is insufficient. The PCs after the two were blended, and the PBT belonged to a plastic alloy, which maintained the chemical resistance and easy molding of the crystalline material PBT, and also had the toughness and dimensional stability of the non-crystalline material PC. [0003] Therefore, the PC, PBT alloy is a thermoplastic alloy with excellent performance, easy processing, and low quality, and is a thermoplastic project with a very commercial value. In the past 5 years, the production of PCs and PBT alloys inc...

Problems solved by technology

However, the addition of flame retardant materials will destroy the original internal structure of PC and PBT alloys, greatly reduce the mechanical properties of PC and PBT alloy materials, and make PC and PBT alloys not resistant to aging and acid-base corrosion resistance.
