Description
Technical field
The present invention relates to the recovery and utilization technology field of HIPS reworked material, be specifically related to a kind of regeneration HIPS environment protection modification material and preparation method thereof.
Background technology
China Today has entered household electrical appliance and has discarded peak period, scraps household appliances every year by generation more than 3,000 ten thousand, and so huge waste household appliances certainly leads to a large amount of waste or used plastics.The recycling of waste or used plastics has sanitary landfill, burns heat-obtaining, and resource recycling three kinds of modes, and wherein landfill easily causes the wasting of resources and secondary pollution with burning, and this runs counter to the themes of the times of environmental protection.
Nowadays, the mode of regeneration is mainly taked in the recycling of waste or used plastics, mainly comprises Direct Regeneration, modification regeneration, gasification and oiling process.But the Mechanical Properties of Products of Direct Regeneration declines comparatively large, should not make high-grade goods; Plastics high-temperature gasification, oiling are high with the technical difficulty reclaiming the low component product such as monomer, fuel oil, equipment scale is large; And some mechanical property of the goods of modification regeneration can meet or exceed the performance of unmodified resin goods, there is very high added value.Therefore, the modification regeneration of waste or used plastics is the developing direction of resource utilization recycling.
In China, the major consumers field of polystyrene PS is electric equipment products, accounts for 60 % of polystyrene total quantity consumed; And in electric equipment products, plastic components with high-impact polystyrene (HIPS) and ABS resin in the majority, wherein HIPS just account for 56 %, though all the other kinds are many, amount is few.Visible, when electric equipment products once scrap, that will bring the HIPS waste or used plastics of substantial amounts.If can be the channel of the recovery of this part HIPS waste or used plastics developing green and regeneration, so not only alleviate waste pollution on the environment, can turn waste into wealth again, economize on resources.
HIPS meets fire easily burning, and discharges a large amount of dense smoke and obnoxious flavour.In order to make product meet flame-retardancy requirements, fire retardant must be added and carry out modification.At present, domestic market mainly adopts halogen-containing organism (TDE, octa-BDE, tetrabromo-bisphenol) and antimonous oxide (Sb
2o
3) composite bromide fire retardant produces flame retardant type HIPS.But owing to being subject to the puzzlement of Dioxins problem in recent years, simultaneously bromo-antimony fire-retardant macromolecular material of uniting can generate a large amount of flue dust and corrosive gases when thermo-cracking and burning, therefore European Union promulgates dependent instruction, requires member states to guarantee to be invested in the new electronics in market and electric equipment products do not comprise the objectionable impuritiess such as poly-dibromodiphenyl ether and poly-bromo biphenyl.Current domestic and international many Research Centers in one's power major company have carried out the research of environmental-protection flame-retardant HIPS all in succession.
Summary of the invention
The object of the invention is for deficiency of the prior art, provide a kind of regeneration HIPS environment protection modification material, it has good flame retardation effect, and material is excellent in cushion effect, and the cost of material is low, well pollution-free to environment, is environmental type twice-laid stuff.
Another goal of the invention of the present invention is to provide a kind of preparation method regenerating HIPS environment protection modification material, and its HIPS purity with the HIPS reclaimed materials obtained is high, and impurity is few, and preparation technology is easy, easily realizes the feature of industrialization.
Object of the present invention is achieved through the following technical solutions:
A kind of regeneration HIPS environment protection modification material, is made up of the material of following weight part:
HIPS reclaimed materials 100 parts
Toughner 3-6 part
Fire retardant 15-20 part
Retardant synergist 0.5-1 part
Anti-impact modifier 10-12 part
Oxidation inhibitor 1-2 part
Coupling agent 1-4 part
Lubricant 2-5 part
Stablizer 2-5 part,
Wherein, described fire retardant to be mixed with polynite-cetyl trimethylammonium bromide by the composite flame-retardant agent of high ammonium polyphosphate, magnesium hydroxide and zinc borate and forms; Described retardant synergist is hydrotalcite chemicals and red phosphor masterbatch is the mixture of 1.8-2:1 in mass ratio, and described anti-impact modifier is waste and old TPR material for sole of shoe, and the particle diameter of described waste and old TPR material for sole of shoe is 3-8 μm.
Hydrotalcite-based compound is anionic compound, and interlayer has tradable negatively charged ion, has certain weakly alkaline, forms primarily of hydrotalcite, houghite and their intercalation chemistry product pillared hydrotalcite.Owing to being made up of the metal oxide of two kinds of different price types between hydrotalcite lamellar compound laminate, so also known as layered bi-metal oxide compound.Typical hydrotalcite-based compound Mg
6al
2(OH)
16cO
34H
2o, have be similar to brucite positive eight and body structure.
Hydrotalcite-based compound is mainly stoped by 3 kinds of approach or delays the generation of fire: the temperature that (1) thermal endothermic decomposition can reduce material compares other inorganic combustion inhibitors, as magnesium hydroxide, aluminium hydroxide etc., hydrotalcite-based compound has wider pyrolysis temperature range and better flame retardant properties.With red phosphor masterbatch synergistic effect, improve flame retardant effect further, reduce costs.
Preferably, when the quality of hydrotalcite chemicals and red phosphor masterbatch is 2:1, flame retardant effect is more excellent.
HIPS reclaimed materials is substantially all belong to waste and old electronics, the reclaimed materials of electric equipment products, and due to seriously aging, shock resistance is low, easily embrittlement occurs, and glossiness is low.
Further, a kind of regeneration HIPS environment protection modification material, is made up of the material of following weight part:
HIPS reclaimed materials 100 parts
Toughner 4-5 part
Fire retardant 15-16 part
Retardant synergist 0.5-0.8 part
Anti-impact modifier 10-12 part
Oxidation inhibitor 1-2 part
Coupling agent 2-3 part
Lubricant 2-4 part
Stablizer 3-4 part.
Preferably, a kind of regeneration HIPS environment protection modification material, is made up of the material of following weight part:
HIPS reclaimed materials 100 parts
Toughner 4 parts
Fire retardant 20 parts
Retardant synergist 0.6 part
Anti-impact modifier 11 parts
1 part, oxidation inhibitor
Coupling agent 2 parts
Lubricant 3 parts
Stablizer 3 parts.
Wherein, in described composite flame-retardant agent, the weight ratio of high ammonium polyphosphate, magnesium hydroxide and zinc borate is 1.5:2.5:7.When above-mentioned three kinds of components proportionally mix, the flame retardant effect of whole system is best, and when acting synergistically with retardant synergist, the oxygen index of system is up to 32.
