preparation example Construction

[0038] Correspondingly, the present invention also provides a preparation method of a UL-94 V0 grade flame-retardant HIPS composite material, comprising the following steps:

[0039] S01 Weighing formula components

[0040] According to above-mentioned UL-94 V0 level flame retardant HIPS compound formula, take described HIPS, fire retardant, anti-dripping agent, white oil, compatibilizer, antioxidant and lubricant respectively;

[0041] S02 Preparation of mixed materials

[0042] Mixing the HIPS, flame retardant, anti-dripping agent, white oil, compatibilizer, antioxidant and lubricant weighed in step S01 to obtain a mixed material;

[0043] S03 melt extrusion

[0044] Put the mixed material obtained in step S02 into a twin-screw extruder, melt extrude, and granulate to obtain the 0.8mm thickness meeting the UL-94 V0 flame-retardant HIPS composite material, and the twin-screw melt-extruded The process parameters are: the temperature of the first zone is 160-190°C, the tempe...

Embodiment 1～5

[0049] The specific components by weight percentage of each HIPS composite material in Examples 1-5 are shown in Table 1 below.

[0050] The preparation method of each HIPS composite material in the above-mentioned embodiments 1-5 is the same, and all comprises the following steps:

[0051] (1) All the components of each HIPS composite material in the above-mentioned embodiments 1 to 5 are weighed by the specific proportions in Table 1 to take each component;

[0052] (2) carrying out the mixing treatment of the above-mentioned components in a mixer to obtain a mixed material;

[0053] (3) Put the mixed material in a screw extruder for melt extrusion and granulation to obtain a HIPS composite material. Among them, the temperature of each section of the extruder is: the first zone is 190°C, the second zone is 210°C, the third zone is 180°C, the fourth zone is 200°C, and the head temperature is 210°C.

Abstract

The invention discloses a UL-94 V0 level flame-retardant HIPS (high impact polystyrene) composite material and a preparation method thereof. The HIPS composite material is prepared from, by weight, 69-83.4% of HIPS, 12-20% of flame retardant, 0.1-0.5% of an anti-dropping agent, 1-1.4% of white oil, 3-7% of a compatilizer, 0.2-0.6% of an antioxidant and 0.3-1.5% of a lubricant. By addition of the anti-dropping agent into HIPS which serves as a matrix to improve combustibility of the HIPS material, efficient flame retardation is realized; by synergistic effects of the lubricant and the compatilizer, a two-phase separation state in the HIPS is improved while compatible dispersion of components is promoted, and accordingly a stable structure is formed; by synergistic effects of industrial-grade white oil and the lubricant, demoulding property and fluidity of the material in processing are improved, and excellent brightness and surface effects of the composite material can be achieved.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a UL-94 V0 flame-retardant HIPS composite material and a preparation method thereof. Background technique [0002] High impact polystyrene resin (High impact polystyrene, referred to as HIPS) is an amorphous thermoplastic resin produced by adding micron-sized polybutadiene (PB) rubber particles to polystyrene (PS), which has good Mechanical properties, but because HIPS contains 5% to 15% rubber, its fluidity will be affected during processing, and PB rubber is incompatible with PS resin, so the butadiene and styrene segments in HIPS are aggregated separately, presents a state of phase separation. In addition, the gloss performance of HIPS material is poor, and its physical and mechanical strength is low, and it shows large shrinkage at low temperature. HIPS has a low oxygen index and belongs to flammable materials. [0003] The traditional meth...
