Problems solved by technology

Disadvantages: the addition of flame retardant resin is relatively large, it is difficult to mix the two polymers evenly, and some of them cannot be mixed at all
Disadvantages: its volatility, large amount of smoke, poor hydrolytic stability and thermal stability, and this kind of flame retardant is expensive, so the cost of flame retardant is high
Although the LD50 of tris(2,3-dibromopropyl)phosphate is greater than 24,000, it has been banned in many countries due to its suspected carcinogenicity

The present invention provides an ABS / polyester alloy material, particularly to a halogen-free fire retardation ABS / PMMA / polyester alloy material, and belongs to the technical field of polymer materials. The fire retardation ABS / PMMA / polyester alloy material comprises the following components, by weight, 100-150 parts of ABS, 20-30 parts of PMMA, 10-20 parts of poly(butylene terephthalate), 10-15 parts of chlorinated polyvinyl chloride, 5-10 parts of polycaprolactone, 5-10 parts of calcium stearate, 4-8 parts of phenylphosphonic acid, 4-8 parts of antimony trioxide, 3-6 parts of an antioxidant, 3-6 parts of a toughening agent, 4-7 parts of a coupling agent, 1-2 parts of an ultraviolet absorber, 3-5 parts of a smoke suppression agent, 5-10 parts of talc powder, and 4-8 parts of potassium titanate crystal whisker. According to the present invention performances of ABS, PMMA, PBT and other resin materials are comprehensively utilized, fire retardation can achieves 0 grade, and the material does not contain halogen, and has good mechanical strength.

Description

[0001] technical field [0002] The invention provides an ABS / polyester alloy material, in particular relates to a halogen-free flame-retardant ABS / PMMA / polyester alloy material, which belongs to the technical field of polymer materials. [0003] Background technique [0004] ABS plastic is a kind of engineering plastic with excellent performance. ABS resin is a terpolymer of polyacrylonitrile (A), butadiene (B) and styrene (S), and is a thermoplastic engineering plastic developed in the 1940s. It organically unifies the various properties of PS, PBR, and PAN. It not only has excellent mechanical properties with balanced toughness, hardness, and rigidity, but also has good chemical resistance, dimensional stability, surface gloss, and low temperature resistance. Properties, coloring performance and processing fluidity and other properties. Because of these characteristics, ABS has been widely used. Its excellent electrical properties, chemical stability and impact resist...
