Problems solved by technology

[0004] With the development of society and people's increasing emphasis on safety, some household appliances and electronic products have put forward higher requirements for flame retardant materials. For example, the shells of electronic controllers such as refrigerators and microwave ovens require 5VA flame retardant, and the thickness also increases with The design trend is becoming thinner and thinner (2.5-2.0mm), and the existing ordinary V-0 flame-retardant HIPS materials can no longer meet this requirement

Abstract

The invention discloses a high flame-retardant grade HIPS composite material, which comprises the following components in parts by weight: 40-60 parts of PS resin, 10-27 parts of thermoplastic styrene-butadiene rubber, 3-10 parts of toughening agent, and 10 parts of flame retardant ~18 parts, 2.5~6 parts of flame retardant synergist, 5~20 parts of inorganic filler, 0.1~0.5 parts of anti-dripping agent and 0~2 parts of auxiliary agent; the weight average molecular weight of the PS resin is greater than or equal to 15* 10 4 g / mol, the melt flow rate MFR is 3~6g / 10min. The high flame retardant grade HIPS composite material of the present invention: 1. High flame retardant grade, the highest can reach 2.0mm 5VA grade; 2. Good comprehensive performance, balanced strength and notch impact performance; 3. Low cost, can replace high Flame retardant grade ABS; 4. Good appearance and wide processing window.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a high flame-retardant grade HIPS composite material. Background technique [0002] Polystyrene (PS) includes ordinary polystyrene, expanded polystyrene (EPS), high-impact polystyrene (HIPS) and syndiotactic polystyrene (SPS). BASF began commercial production in Germany in 1930 polystyrene. As one of the five general-purpose plastics, it has the advantages of excellent formability, hard quality, transparency, rigidity, electrical insulation, low hygroscopicity, easy dyeing and low price. [0003] High-impact polystyrene (HIPS) is produced by adding a small amount of elastomer to PS, which overcomes the brittleness of polystyrene, so it is widely used in internal and external components of household appliances and office automation equipment. Such as monitors, video recorders, copiers, fax machines, printers, air conditioners, refrigerators, etc. Styrenic polymers ...
