ABS (Acrylonitrile Butadiene Styrene) environment-friendly inflaming retarding compound material and preparation method thereof

Abstract

The invention discloses an ABS (Acrylonitrile Butadiene Styrene) environment-friendly inflaming retarding compound material which comprises the following components by weight percent: 55%-90% of acrylonitrile-butadiene-styrene ternary copolymer, 5%-30% of Tri(tribromophenyl) cyanurate, 1%-15% of antimonous oxide, 0.9%-20% of compound silicate material and 0.1%-1% of anti-dropping agent. The inflaming retarding property of the material is increased and the cost is lowered, by adding the compound silicate material and the like, into the ABS. The invention also discloses a preparation method of the ABS environment-friendly inflaming retarding compound material. The preparation method comprises the following steps of: uniformly mixing the raw materials; adding the mixed raw materials into a double-screw extruder for fusing and mixing, and then performing melt extrusion; and pelletizing, thereby obtaining the ABS environment-friendly inflaming retarding compound material. The preparation is simple; the operation is convenient; the prepared ABS environment-friendly inflaming retarding compound material is excellent and stable in property; the industrial production is easily performed; the economic benefit is excellent; and the application prospect is wide.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an ABS environment-friendly flame-retardant composite material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer (ABS) has excellent properties such as high toughness, high strength and high gloss, and is widely used in automobiles, electronic appliances and other industries. However, ABS resin is easy to burn in the air, and its oxygen index is only about 18. It is a flammable material, and it releases black smoke and toxic gases when burned, which is prone to fire safety hazards. Therefore, it needs to be flame retardant in many application fields. Smoke suppression treatment. [0003] With the development of society and the increasing awareness of social safety, the use of flame-retardant ABS in the field of electronic appliances has become a social consensus. As people's awareness of environmental protection continues...

Problems solved by technology

Although this technical scheme uses bromotriazine and decabromodiphenylethane as flame retardants, on the one hand bromotriazine effectively ensures the mechanical properties and weather resistance of ABS, and on the other hand decabromodiphenylethane effectively The cost of the system is reduced, but it needs to add UV absorber UV-326, UV absorber UV-531, light stabilizer UV-3346 to improve the anti-ultraviolet performance, and need to increase other conventional additives, such as antioxidant 1010, Antioxidant 168, lubricant EBS, bromotriazine and decabromodiphenylethane flame retardants are added in relatively large amounts, so the actual overall production cost is relatively high
