Abstract
A method for preparing a high-toughness slow-burning HIPS compound by using PS recycled materials belongs to the field of polymer materials. The compound includes the components with weight percentages as follows: 70-90% of various types of PS recycled materials after application, 5-10% of bromine flame retardants, 2-3% of flame-retardant synergist, 4-8% of toughening agent, 1-4% of heat stabilizer, 1-3% of anti-oxidant and 0.5-5% of processing aid, and prepared by adopting processes of high-speed premixing, dispersing and one-time extrusion. The compound solves the problem of preparing recycled plastic HIPS by utilizing the existing various types of waste PS plastic products, has high impact strength, good toughness, flame retardant property reaching FH-3 grade, good lustrous surface and easy processing and forming, is widely applied in the fields of household electrical appliances such as displays, televisions, and the like, and recycles the PS, thus realizing the regeneration and comprehensive utilization of resources, and not causing extra burden on environment.
Description
Technical field
The present invention relates to reclaim the thermoplastic resin composition field in the polymer modification technology, be specifically related to the PS reclaimed materials and make prescription of high tenacity deflagration HIPS mixture and preparation method thereof.
Technical background
HIPS realizes industrialization in nineteen thirty, as one of five big general-purpose plastics, is widely used in industries such as electronics, electrical equipment, automobile, household electrical appliances, instrument, daily necessities, toy for many years; Plastics and plastics are in the evolution of last 100 years; for Human's production and life have brought huge contribution and unlimited convenience; but As time goes on some plastics are after its life cycle finishes; plastic refuse has become an increasingly serious problem; the China plastic working deputy secretary-general of TIA; the plastic reclaimed secretary general Ma Zhanfeng of special commission that utilizes also thinks; landfill is not to tackle waste plastic the best way; he says; " weight of plastics in rubbish is little; volume is big; determined its unsuitable landfill of ultimate disposal; and it is the very high macromolecular material of calorific value; recycle the fundamental state policy that meets China's Sustainable development; also can make full use of its inherent value, and economize on resources; protection environment ".The consumption of PS is big, the amount of the defective material in the production of articles process, mouth of a river material and reclaimed materials is also many, therefore the PS reclaimed materials is carried out modification makes its repeated use, for industry provides high performance regenerative raw materials, for society provides the energy recycle approach of clean and effective, realize that the resource regeneration of plastics is significant.
Summary of the invention:
The object of the present invention is to provide a kind of PS reclaimed materials to make the prescription and the manufacture craft thereof of high tenacity deflagration HIPS mixture, PS is reclaimed modification.
For achieving the above object, the prescription that PS reclaimed materials provided by the invention is made high tenacity deflagration HIPS mixture is to add toughner, toughner, fire retardant, thermo-stabilizer, oxidation inhibitor, processing aid etc. to carry out modification in the PS reclaimed materials, delay performance thereby improve mechanical property and burning, realize the economic recovery utilization.
