Abstract
The invention provides a high-oxygen-index low-smoke flame-retardant ABS material which is prepared from the following raw materials in parts by weight: ABS resin: 60-85 parts; halogen-based flame retardant: 10-20 parts; flame retardant synergist: 0.8-5 parts; an organic silicon toughening agent: 3-15 parts; smoke suppressant: 0.8-5 parts; lubricant: 0.1-1 part; antioxidant: 0.1-2 parts. The ABS material and the preparation method thereof can obtain the ABS material with high oxygen index, high elongation at break, environmental protection, low smoke, scratch resistance and flame retardance, and not only has good mechanical property, but also has low smoke, flame retardance and high safety.
Description
Technical Field
The invention belongs to the field of high polymer materials, and particularly relates to a high-oxygen-index low-smoke flame-retardant ABS material and a preparation method thereof.
Background
The ABS resin is a terpolymer consisting of styrene, butadiene and acrylonitrile, integrates the high fluidity of the styrene, the rubber toughness of the butadiene and the chemical resistance of the acrylonitrile, has excellent processability, low temperature resistance, electric insulation performance, chemical corrosion resistance, high gloss and excellent electroplating performance, has the excellent characteristics of good creep resistance, high dimensional stability, small molding shrinkage and the like, and is widely applied to the fields of war industry, automobiles, electronic and electric appliances and the like.
However, the oxygen index of the ABS resin is only 18, and it is a flammable material. Therefore, the flame retardant modification of the ABS resin is a common modification method of the ABS resin at present. There are two main categories of these flame retardant modification techniques: one is halogen flame retardant, for example, flame retardant containing bromine and flame retardant synergist of antimony oxide are added to achieve flame retardant effect; another class is halogen-free flame retardant, for example, incorporating phosphorus-containing, nitrogen-containing flame retardants and char-forming agents. The first kind (halogen flame retardant) of flame retardant technology has relatively low cost and high flame retardant efficiency, and is the most widely used technology at present. However, since the styrene-based polymer contains benzene rings and unsaturated double bonds, a large amount of smoke is generated during combustion, and the amount of smoke generated by the halogen-antimony system flame retardant material is even greater. In the using process, once a fire accident happens, the generation of smoke and toxic gas can not only cause oxygen deficiency asphyxiation, but also cause low visibility in dangerous areas, which is not beneficial to rescue and causes casualties and property loss.
Disclosure of Invention
In view of this, the invention aims to provide a high-oxygen-index, low-smoke and flame-retardant ABS material and a preparation method thereof, so as to obtain the high-oxygen-index, high-elongation at break, environment-friendly, low-smoke, scratch-resistant and flame-retardant ABS material, which not only has good mechanical properties, but also has low-smoke and flame-retardant properties and high safety.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a high-oxygen-index low-smoke flame-retardant ABS material is prepared from the following raw materials in parts by weight:
further, the ABS resin is a terpolymer of acrylonitrile, butadiene and styrene, wherein the weight percentage content of the butadiene is 10-55%, the weight percentage content of the acrylonitrile is 15-32%, and the weight percentage content of the styrene is 30-70%.
Further, the ABS resin is at least one of bulk ABS and emulsion ABS.
Further, the halogen flame retardant is one or more of chlorinated polyethylene, polytetrafluoroethylene, decabromodiphenylethane, brominated epoxy resin, brominated polystyrene, tetrabromobisphenol A, brominated triazine or tribromophenol isocyanate.
Further, the weight ratio of the antimony trioxide to the molybdenum trioxide is 3:1-1: 3.
The compound of antimony trioxide and molybdenum trioxide is used, so that the flame retardant effect is improved, and the smoke suppression effect is achieved. On one hand, the flame retardant synergistic agent has the function of a flame retardant synergistic agent, and the two compounds and the halogen flame retardant have the flame retardant synergistic effect, so that the flame retardant efficiency of the material can be greatly improved; on the other hand, the two compounds can also play a role of a smoke suppressant, wherein molybdenum trioxide promotes the production of a carbon layer and reduces the smoke amount through Lewis acid, and the addition of molybdenum trioxide is beneficial to forming a relatively stable pi-aromatic complex and reducing the production of benzene and toluene, so that the smoke amount is reduced.
In addition, the oxygen index of the material can be greatly improved by using the compound of antimony trioxide and molybdenum trioxide.
Further, the organosilicon toughening agent is polysiloxane rubber.
Polysiloxane rubbers can serve three functions in the formulation, first, toughening: under the impact of external force, the rubber in the multipolymer can keep good deformation and movement capability and still can initiate a large amount of silver lines and shear bands on an ABS matrix, thereby improving the toughness of the material. Secondly, smoke suppression: upon combustion, the organosilicon-rich layer formed upon migration of the organosilicon to the surface of the material produces an inorganic oxygen-and heat-insulating protective layer containing Si bonds and/or Si-C bonds, which is characteristic of polysiloxanes. This not only prevents the combustion decomposition product from escaping, but also inhibits the thermal decomposition of the high molecular material, and achieves the purposes of flame retardance, low smoke, low toxicity, etc. Thirdly, scratch resistance: migration of the silicone to the surface can improve the stick-slip behavior of the material, thereby enhancing the scratch resistance of the material.
Further, the organic iron additive is one or more of ferrocene, benzoyl ferrocene and ferric acetylacetonate.
The smoke suppression effect of the organic iron additive mainly occurs in a condensed phase on the halogen-containing high polymer to promote the crosslinking of the polymer; organic iron additives form FeX during the combustion of halogen-containing polymers4Promoting carbonization and having excellent flame-retardant and smoke-inhibiting effects. Therefore, the matching action of the organic iron additive and the halogen flame retardant can play a better smoke suppression role.
Further, the antioxidant is one or a mixture of phenols, phosphites, sulfur-containing esters and metal passivators.
Wherein the phenolic antioxidant is preferably 2, 4, 6-tri-tert-butylphenol, 2-methylenebis (4-methyl-6-tert-butylphenol) or pentaerythrityl tetrakis [ β - (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate ];
the phosphite antioxidant is preferably tris (nonylphenyl) phosphite or tris (2, 4-di-tert-butylphenyl) phosphite;
the sulfur-containing ester antioxidant is preferably dilauryl thiodipropionate or distearyl thiodipropionate; the metal deactivator antioxidant is N, N-diacetyl adipoyl dihydrazide, N-salicylidene-N-salicylidene hydrazide or disalicylhydrazine.
The antioxidant is added for the purpose of improving the thermal stability of the composite material and preventing the composite material from degrading in the process of extruding, granulating or injection molding a workpiece; another object is to improve the long term aging properties of the composite.
Further, the lubricant is silicone oil.
The addition of the silicone oil can improve the lubricating effect of the material and also play a role in smoke suppression and scraping resistance.
