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 HIPS composite material with high flammability. The HIPS composite material comprises the following components in parts by weight: 40-60 parts of PS resin, 10-27 parts of thermoplastic butadiene styrene rubber, 3-10 parts of flexibilizer, 10-18 parts of fire retardant, 2.5-6 parts of flame retardant synergist, 5-20 parts of inorganic filler, 0.1-0.5 part of anti-drippingagent and 0-2 parts of auxiliaries; weight-average molecular weight of PS resin is more than or equal to 15*104g / mol; melt flow rate MFR is 3-6g / 10min. The HIPS composite material with high flammability disclosed by the invention has the following advantages: 1) high flame retardant level (maximal level can reach up to 2.0mm 5VA level); 2) excellent overall performance and balanced strength and notch impact property; 3) low cost and capability of substituting high-flammability ABS in some situations; 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 ...
