Flame-retardant blister PC/ABS alloy material as well as preparation method and application thereof

Abstract

The invention discloses a flame-retardant blister PC / ABS alloy material as well as a preparation method and application thereof, and belongs to the technical field of organic synthetic materials. Theflame-retardant blister PC / ABS alloy material comprises the following components in parts by weight: 73 to 74 parts of PC-122, 9 to 11 parts of PA-1730, 3 to 5 parts of an interface toughening compatilizer, 7 to 9 parts of a phosphonitrile flame retardant, 2.5 to 3.5 parts of a plasticizing flame retardant synergist, 0.3 to 0.5 part of an anti-dripping agent, 0.45 to 0.55 part of a lubricating agent and 0.15 to 0.25 part of an antioxidant. The plasticizing flame-retardant synergist is triphenyl phosphate or diphenyl phosphate. The PC / ABS alloy material provided by the invention is relatively good in comprehensive performance, relatively good in plastic uptake and high in saturation degree.

Description

technical field

[0001] The invention relates to the technical field of organic synthetic materials, in particular to a flame-retardant plastic-absorbing PC / ABS alloy material and a preparation method and application thereof. Background technique

[0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. PC has the advantages of high impact strength, good creep resistance and dimensional stability, heat resistance, and excellent dielectric properties, but also has disadvantages such as poor processing fluidity, easy stress cracking, sensitivity to notches, and poor chemical resistance. ABS resin is a terpolymer (acrylonitrile-butadiene-styrene) developed on the basis of polystyrene (PS) resin modification. It is a kind of good performance between engineering plastics and general-purpose p...
