A kind of high black flame retardant abs compound with matting effect and preparation method and application thereof

Abstract

The invention provides a high-black flame-retardant ABS compound with matting effect, a preparation method and application thereof, and comprises the following components by mass percentage: 60-77% of ABS resin; 3-20% of high rubber powder; Flame Retardant 5~20%; Flame Retardant Synergist 1~5%; Matting Agent 1~5%; High Blackness Toner 0.1~1%; Anti-dripping Agent 0.1~0.5%; Processing Aid 0.1~ 1%; the high-blackness toner is a compound of inorganic black powder and organic black powder; the mass ratio of inorganic black powder to organic black powder in the compound is (16-35): (33- 150); Preferably, the mass ratio of inorganic black powder and organic black powder is (20-32): (45-110). The ABS compound created by the invention has the characteristics of high blackness, and the blackness value of the material can reach <26.2.

Description

technical field [0001] The invention belongs to the technical field of ABS materials, and in particular relates to a high-black flame-retardant ABS compound with matting effect and a preparation method and application thereof. Background technique [0002] Styrene-butadiene-acrylonitrile copolymer (ABS) is an engineering plastic with excellent comprehensive properties, high impact strength, good dimensional stability, wear resistance and easy molding and processing. It is widely used in auto parts, household appliances, Office equipment, instrumentation, transportation, building materials, household appliances and packaging materials and other fields. [0003] On the one hand, the oxygen index of ABS resin is only 18, which is a flammable material. Therefore, flame retardant modification of ABS resin is a commonly used method for ABS resin modification. [0004] At present, the commonly used flame retardant systems of ABS are halogen-based flame retardants and antimony tri...

AI Technical Summary

Problems solved by technology

[0004] At present, the flame retardant system commonly used in ABS is a synergistic system of halogenated flame retardants and antimony trioxide, and the refractive index of antimony trioxide is 2.1, which has a strong hiding power, and a large amount of brominated flame retardants are added It will also affect the background color of flame-retardant ABS, so the blackness of flame-retardant ABS is usually relatively low, and it cannot meet the use requirements when using panel parts with higher blackness requirements

The direct and effective way to increase the blackness of flame retardant ABS is to increase the amount of carbon black powder, but when the amount of carbon black powder added is large, it is easy to agglomerate, resulting in serious pitting
