Embodiment 1

[0029]Example 1: Step 1: HIPS resin, bis(4-allyloxy-3,5-dibromophenyl) sulfone, compound of antimony trioxide and molybdenum trioxide, acrylic acid-polysiloxane Rubber-acrylonitrile styrene multi-polymer, ferrocene ketone, lubricant and antioxidant were added into a high-speed mixer according to the ratio and mixed to obtain a mixture. The mixing time was 10 minutes. The specific component distribution is shown in Table 1 . Step 2: Transport the mixture in step 1 to a twin-screw extruder for shearing and kneading to obtain a molten mixture, wherein the temperature of each section of the twin-screw extruder is 180°C, and the twin-screw extruder The length-to-diameter ratio is 30, and the screw speed is 600 rpm. Step 3: Extrude, granulate, and dry the molten mixture in step 2 to obtain a granular environmentally friendly low-smoke flame-retardant HIPS material. Step 4: Add the granular environment-friendly low-smoke flame-retardant HIPS material in step 3 into an injection mol...

Abstract

The invention provides an environment-friendly low-smoke flame-retardant HIPS material and a preparation method thereof. The environment-friendly low-smoke flame-retardant HIPS material is characterized by comprising the following raw materials in parts by weight: 60-85 parts of HIPS resin; 6 to 15 parts of bis (4-allyloxy-3, 5-dibromophenyl) sulfone; 3-7 parts of a compound of antimonous oxide and molybdenum trioxide; 3-15 parts of an organic silicon toughening agent; 3-6 parts of ferrocene alkyne ketone; 0.1 to 1 part of a lubricant; and 0.1 to 2 parts of an antioxidant. The environment-friendly low-smoke flame-retardant HIPS material has a relatively good low-smoke flame-retardant effect.

Description

technical field [0001] The invention relates to the technical field of polymer modification, in particular to an environment-friendly low-smoke flame-retardant HIPS material and a preparation method thereof. Background technique [0002] Polystyrene is the third largest variety of general-purpose plastics. It has the advantages of transparency, good formability, good rigidity, easy dyeing, low hygroscopicity and low price. It is used in packaging, electronics, construction, automotive appliances, instruments, daily necessities and toys. and other industries have been widely used. But polystyrene is brittle and has low impact strength. Therefore, increasing its toughness has always been an important topic of PS modification. In addition, polystyrene is a flammable material. Therefore, it is usually necessary to add a certain amount of flame retardant to give the material good flame retardancy. However, because styrene polymers contain benzene rings and unsaturated double ...
