Description
Technical field
The present invention relates to the utilization technology field of HIPS reworked materials, and in particular to one kind regeneration HIPS environment protection modification materials
Material and preparation method thereof.
Background technology
China Today has been enter into household electrical appliance and discards peak period, and will produce more than 3,000 ten thousand every year scraps household appliances,
So huge waste household appliances necessarily lead to substantial amounts of waste or used plastics.The recycling of waste or used plastics has sanitary landfills, burning to take
Heat, and three kinds of modes of resource recycling, wherein landfill easily causes the wasting of resources and secondary pollution with burning, this is contrary to
In the themes of the times of environmental protection.
Nowadays, the mode of regeneration is mainly taken in the recycling of waste or used plastics, mainly including Direct Regeneration, modification again
Raw, gasification and oiling processing.However, the Mechanical Properties of Products decline of Direct Regeneration is larger, the product of top grade should not be made；Modeling
Material high-temperature gasification, oiling are big with technical difficulty height, the equipment scale for reclaiming the low component product such as monomer, fuel oil；And modification regeneration
The some mechanical properties of product can reach or more than the performance of elite tree grease article, with very high added value.Therefore, waste or used plastics
Modification regeneration be recycling recycle developing direction.
In China, polystyrene PS major consumers field is electric equipment products, accounts for polystyrene total quantity consumed
60 %；And in electric equipment products, plastic components are with high impact polystyrene（HIPS）It is in the majority with ABS resins, wherein HIPS
56 % are just account for, though remaining species is more, amount is few.It can be seen that, when electric equipment products is once scrapped, that will bring substantial amounts
HIPS waste or used plastics.If green reclaim and the channel of regeneration can be developed for this part HIPS waste or used plastics, then no
Discarded object pollution on the environment is only alleviated, can turn waste into wealth again, economize on resources.
HIPS meets fire easily burning, and discharge substantial amounts of dense smoke and pernicious gas.In order that product meets flame-retardancy requirements,
Fire retardant is must be added to be modified.At present, domestic market mainly uses (TDE, eight bromines containing halogen organic
Biphenyl Ether, tetrabromobisphenol A) and antimony oxide (Sb2O3) compounding bromide fire retardant production flame retardant type HIPS.But due in recent years
To be perplexed by dioxin problem, while bromo- antimony is united, fire-retardant high polymer material can be generated largely in thermal cracking and burning
Flue dust and corrosive gas, therefore European Union promulgate dependent instruction, it is desirable to member state ensures to be invested in the new electronics in market and electricity
Device product does not include the harmful substance such as poly- dibromodiphenyl ether and poly- bromo biphenyl.Many Research Centers major company's all phases in one's power both at home and abroad at present
After the research for having carried out environmental-protection flame-retardant HIPS.
The content of the invention
The purpose of the present invention is that it has there is provided one kind regeneration HIPS environment protection modification materials for deficiency of the prior art
There is good flame retardation effect, material impact strength is high, and the cost of material is low, well pollution-free to environment, is environmental type regenerated material
Material.
Another goal of the invention of the present invention is to provide a kind of preparation method of regeneration HIPS environment protection modification materials, and it has
The HIPS purity of the HIPS reclaimed materials arrived is high, and impurity is few, and preparation technology is easy, the characteristics of easily realizing industrialization.
The purpose of the present invention is achieved through the following technical solutions：
One kind regeneration HIPS environment protection modification materials, by the material composition of following parts by weight：
100 parts of HIPS reclaimed materials
3-6 parts of toughener
15-20 parts of fire retardant
0.5-1 parts of retardant synergist
10-12 parts of anti-impact modifier
1-2 parts of antioxidant
1-4 parts of coupling agent
2-5 parts of lubricant
2-5 parts of stabilizer,
Wherein, composite flame-retardant agent and montmorillonite-ten six of the fire retardant by high ammonium polyphosphate, magnesium hydroxide and Firebrake ZB
Alkyl trimethyl ammonium bromide mixing composition；The retardant synergist is hydrotalcite chemicals and red phosphor masterbatch is in mass ratio
1.8-2：1 mixture, the anti-impact modifier is waste and old TPR material for sole of shoe, the grain of the waste and old TPR material for sole of shoe
Footpath is 3-8 μm.
Hydrotalcite-based compound is anionic compound, and interlayer has tradable anion, with certain weak base
Property, mainly it is made up of hydrotalcite, houghite and their intercalation chemistry product pillared hydrotalcite.Due to hydrotalcite laminarization
