Problems solved by technology

[0005] Patents CN200810066901 and CN201611212463 disclose PVC / ABS alloys, which can achieve high flame-retardant grades, but due to the poor thermal stability of PVC, the processing window is very narrow, which limits its application
[0006] Patents CN201210470130 and CN201310743041 disclose high-flame-retardant ABS and its alloys, but due to the addition of glass fiber / carbon fiber, its appearance is not good
[0007] Patent CN201480014209 discloses a filled polycarbonate composition, the flame retardant is bisphenol A bis(diphenyl phosphate) compounded with a large amount of polytetrafluoroethylene, wollastonite particles, alumina particles or glass fiber And its mixture is filled, but only up to 2.3mm 5VA

Abstract

The invention discloses an ABS composite material, which comprises the following components in parts by weight: 34-78 parts of ABS resin, 0-20 parts of SAN resin, 0-10 parts of toughening agent, 12-20 parts of flame retardant, flame retardant 3-6 parts of synergist, 3-15 parts of inorganic filler, 0.1-0.5 parts of anti-dripping agent and 0-2 parts of auxiliary agent; the average aspect ratio of the inorganic filler is ≥5:1. The ABS composite material of the present invention: 1. High flame retardant grade, the highest grade can reach 1.8mm5VA; 2. Good comprehensive performance, which can achieve a balance of strength and notched impact performance; 3. Good appearance and high gloss; 4. Thermal stability Good performance, wide processing window.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to an ABS composite material. Background technique [0002] ABS resin is a light yellow solid with a density of about 1.04g / cm 3 , because it organically unifies the properties of three different materials: acrylonitrile, butadiene, and styrene, and has both formability, rigidity, and toughness. It has excellent comprehensive properties and is widely used. ABS is suitable for household electrical appliances, such as TV casings, refrigerator linings, vacuum cleaners, etc., as well as plastic products for instruments, telephones, and automobile industries. [0003] Flame-retardant ABS is one of the important directions of ABS modification. It is developed to solve the shortcoming that ordinary ABS resin is easy to burn. The flame retardant grade increases step by step from HB, V-2, V-1, V-0, 5VB to 5VA. Among them, the 5V test requires that after five 5-second combusti...
