Abstract
The present invention is one kind of modified regenerated foamable polystyrene material and its preparation process. The modified regenerated foamable polystyrene material consists of regenerated foamable polystyrene material 5-50 wt%, high impact strength regenerated polystyrene material 15-50 wt%, high impact strength polystyrene 30-60 wt% and toughening agent 1-10 wt%. The preparation process includes the steps of high speed mixing of materials, melting, extruding and palletizing, or is one two-step toughening process. The modified regenerated foamable polystyrene material may be used to replace high impact strength polystyrene resin in some application and has low cost and environment friendship.
Description
Affiliated technical field
It is material modified and preparation method thereof to the present invention relates to a kind of Expandable Polystyrene (EPS), particularly utilizes the Expandable Polystyrene (EPS) and the high-impact polystyrene that reclaim to be raw material production modifying material for foamable polystyrene material and preparation method thereof.
Background technology
Expandable Polystyrene (EPS), promptly EPS is one of most widely used plastics in the world today, is mainly used in household electrical appliances, office machinery amortizing packaging material, container and disposable tableware etc.EPS after the use is because characteristic such as light weight, volume be big, ageing-resistant, anticorrosive so be a great problem of refuse treatment, causes bigger pollution to environment.For effectively handling waste and old EPS, the scientific research personnel has carried out extensive work both at home and abroad, conclude and get up to have following mode: hot melt regeneration, thermo-cracking (catalytic pyrolysis) system monomer and oil fuel, modification regeneration system coating, tackiness agent, heat-insulation and heat-preservation material, blend system polymer alloy, gel method regeneration, solvent method regeneration, burning recovered energy and extruding regenerated plastic board material etc.More than waste and old EPS is handled the characteristics that have separately, but generally speaking processing cost is higher, suitability for industrialized production mainly is melt pelletization and produces coating or tackiness agent at present, the otherwise processed amount seldom, to produce secondary pollution simultaneously, the unit price height of finished product, practical value reduces.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of waste and old Expandable Polystyrene (EPS) and waste high impact polystyrene of utilizing to be raw material production modifying material for foamable polystyrene material and preparation method thereof, thereby solve the pollution of EPS, make full use of waste high impact polystyrene environment.The modifying material for foamable polystyrene material cost of Sheng Chaning is low simultaneously, and performance is good, satisfies the index request of producing products such as televisor back cover fully, and alternative high-impact polystyrene is the HIPS material.
The solution of invention is: a kind of modifying material for foamable polystyrene material is characterized in that comprising following component:
Expandable Polystyrene (EPS) reclaimed materials 5-50%
High-impact polystyrene reclaimed materials 15-50%
High-impact polystyrene resin 30-60%
Toughner 1-10%
Wherein said toughner is butadiene-styrene block copolymer, and the stearate that accounts for gross weight 0.05-0.1%.
One of preparation method of above-mentioned modifying material for foamable polystyrene material carries out according to the following steps:
A, raw material pressed add processing aid and oxidation inhibitor after the component proportioning;
B, make modifying material for foamable polystyrene material by following processing step:
High-speed mixing → fusion → extrude → pelletizing.
The preparation method's of above-mentioned modifying material for foamable polystyrene material two carries out according to the following steps:
A, with raw material by following weight percent proportioning:
High-impact polystyrene reclaimed materials 20-65%
Expandable Polystyrene (EPS) reclaimed materials 25-65%
Toughner 3-18%
Wherein toughner is butadiene-styrene block copolymer;
B, will be in the above-mentioned batching add behind processing aid and the oxidation inhibitor to make and reclaim compound material by following processing step:
High-speed mixing → pre-dispersed → mediate → dissolve → extrude;
C, will reclaim compound material and high-impact polystyrene resin by following proportion ingredient:
Reclaim compound material 42-62%
High-impact polystyrene resin 38-58%
0.05-0.1% by above-mentioned batching gross weight adds stearate, makes modifying material for foamable polystyrene material by following processing step behind adding processing rib agent and the oxidation inhibitor again:
High-speed mixing → fusion → extrude → pelletizing.
Processing aid and oxidation inhibitor only are that polystyrene in the machining process is played a protective role in the solution of the present invention; in the course of processing, will extract out or volatilize; processing aid can adopt the mixture of white mineral oil and silicone oil; oxidation inhibitor plays stabilizer function, and processing aid and added quantity of antioxidant are the 0.1-0.3% of raw material gross weight.The present invention can make by disposable toughness reinforcing complete processing by proportioning raw materials.But because the EPS self performance is relatively poor, volume is big, compression ratio is low, can't directly use, must carry out pre-deaeration, shock strength is low after the deaeration, contain a large amount of impurity in the HIPS reclaimed materials simultaneously, so will adopt the toughness reinforcing complete processing of secondary to make for obtaining better effect among the preparation method, be about to the EPS reclaimed materials, HIPS reclaimed materials and toughner carry out premix, produce and reclaim compound material, reach the removal bubble, impurity, pre-mixing increases the toughness effect, adds the HIPS virgin material then in reclaiming compound material, toughner, processing aid, oxidation inhibitor carries out the twice-modified performance index that make the modifying material for foamable polystyrene material of producing reach the HIPS resin.
Each component reaches performance the best by following proportioning in the solution of the present invention:
Expandable Polystyrene (EPS) reclaimed materials 19%
High-impact polystyrene reclaimed materials 28.4%
High-impact polystyrene resin 48%
Toughner 4.6%
The present invention adds the HIPS resin by adopting recovery EPS and reclaiming HIPS and make raw material, adds toughner and carries out modification, by resin treatment technology, thereby makes product performance reach the requirement of HIPS resin.Correspondingly the invention provides a kind of method that solves waste and old EPS environmental pollution, made full use of waste and old HIPS simultaneously, make the modifying material for foamable polystyrene material cost of production low, performance good, after tested, the complete alternative high-impact polystyrene resin of modifying material for foamable polystyrene material of the present invention is used as products such as televisor back cover.
