Problems solved by technology

However, these two materials need to actively add antimony oxide to achieve flame retardant performance, and antimony itself is a non-renewable resource and a heavy metal, which is not conducive to environmental protection. Although the materials prepared by the patent have high transparency, the patent produced The material does not have infrared pass through and laser engraving function

Abstract

The invention relates to the field of technologies for preparing resin compositions, in particular to an infrared-permeable transparent flame-retardant composite material and a method for preparing the same. The infrared-permeable transparent flame-retardant composite material comprises, by weight, 70-83 parts of MABS (methyl methacrylate-acrylonitrile-butadiene-styrene) resin, 10-20 parts of bromo-triazine, 1-5 parts of low-polymer aryl phosphate ester, 3-8 parts of toughening agents, 0.1-0.5 part of laser engraving auxiliaries, 0.2-0.5 part of antioxidants, 0.9-2 parts of polyamide wax and 0-2.0 parts of color powder. The infrared-permeable transparent flame-retardant composite material and the method have the advantages that environmental protection requirements can be met by the infrared-permeable transparent flame-retardant composite material which is an ABS (acrylonitrile-butadiene-styrene) composite material, the infrared-permeable transparent flame-retardant composite material has an excellent laser engraving function, is high in transparency and flame-retardant property and excellent in injection molding machining property, and excellent infrared permeation effects can be realized; the infrared-permeable transparent flame-retardant composite material can be widely applied to the field of remote-control electric appliances, and universal infrared permeation polycarbonate materials on markets can be replaced.

Description

technical field [0001] The invention relates to the technical field of resin composition preparation, in particular to an infrared-transparent transparent flame-retardant composite material and a preparation method thereof. Background technique [0002] Infrared-transparent materials allow infrared rays within a specific wavelength range to pass through without absorption or reflection. As a key material in infrared technology, infrared transparent materials are widely used in infrared remote control receivers, infrared sensors, glasses, night vision equipment, infrared rays, etc. Traditional infrared transmission materials are generally made of transparent materials such as PC, PMMA, MABS and PS. Although PC has high transparency and flame retardancy, PC has a high melting temperature, is difficult to process, and is not resistant to chemical reagents, and injection-molded products The internal stress is large and it is easy to crack, which limits its application in the fi...
