Problems solved by technology

In the past, only ultra-thick products could be injected to make up for the defect of excessive brittleness. The sales price after granulation is also very cheap, and the cost cannot be recovered at all.

Embodiment 1

[0038] Enhanced flame retardant (UL94 / V-0) HIPS material is manufactured according to the following material ratio in parts by weight:

[0039] Regenerated flame retardant HIPS: 76 parts

[0040] Compatibilizer SBR: 6 parts

[0041] Flame retardant: 6 parts

[0042] Recycled flame retardant ABS: 10 parts

[0043] Lubricant: 0.7 parts

[0044] Antioxidant: 0.7 parts

[0045] Anti-dripping agent: 0.6 parts

[0046] The preparation process of enhanced flame retardant (UL94 / V-0) HIPS includes steps:

[0047] A. First pass the broken flame-retardant HIPS or flame-retardant ABS through the salt water with adjusted density, float the flame-retardant HIPS and flame-retardant ABS above the salt water, wash away some impurities, and then pass the flame-retardant HIPS and flame-retardant ABS through Adjust the density of the brine so that it sinks below the brine to clear impurities again.

[0048] B. Dehydrate the flame-retardant HIPS or ABS cleaned in step A, and pack them into ...

Embodiment 2

[0053] The enhanced flame retardant (UL94 / V-0) HIPS material consists of the following parts by weight:

Abstract

The invention relates to the technical field of high-polymer modification, particularly a special reinforced regenerated flame-retardant HIPS (high impact polystyrene) for home appliances and a preparation technique thereof. The HIPS is prepared from the following components in parts by weight: 55-90 parts of regenerated flame-retardant HIPS, 0-30 parts of regenerated flame-retardant ABS (acrylonitrile-butadiene-styrene), 0-10 parts of compatilizer, 0-10 parts of flame retardant, 0.3-2 parts of lubricant, 0.2-2 parts of antioxidant and 0.3-0.8 part of anti-dripping agent. The regenerated flame-retardant ABS is utilized to reinforce the regenerated flame-retardant HIPS, thereby solving the problem that the flame retardancy, toughness and strength of the flame-retardant HIPS recovered in the prior art can not simultaneously satisfy the demands; and thus, the regenerated flame-retardant HIPS has favorable toughness on the premise of having higher flame retardancy. The compatilizer is utilized to well solve the problem of embrittlement when the regenerated flame-retardant HIPS and the regenerated flame-retardant ABS are simply blended, and enhances the tensile strength of the HIPS on the premise of ensuring the flame retardancy and toughness of the material. No additional grafting compatilizer is added to enhance the compatibility of the material.

Description

technical field [0001] The invention relates to the technical field of polymer modification, in particular to an enhanced regeneration flame-retardant HIPS specially used for household appliances and a preparation process thereof. Background technique [0002] High-impact polystyrene (HIPS) is a material with excellent comprehensive properties, with excellent mechanical properties, electrical insulation, processability and other advantages. In order to meet people's use requirements, people have modified HIPS with flame retardancy. Flame-retardant HIPS is widely used in the home appliance industry, such as display back shells, audio shells, etc. [0003] At present, due to its low price, the regenerated flame-retardant HIPS can be modified by adding some flame retardants, tougheners, and other additives, which can greatly reduce the cost. At present, many domestic appliance manufacturers use imported flame-retardant HIPS. modified for recycling. Regenerated flame-retardan...
