Abstract
The present invention discloses polymer material modified with hard asphalt as stuffing and its preparation process. High softening point asphalt as one kind of side product of petroleum industry is added into polymer material and foamed to prepare modified polymer material. The said method can improve the performance of polymer material in relatively low cost. The present invention is significant in optimizing heavy oil producing process and expanding the application range of polymer material.
Description
Technical field
The present invention relates to a kind of method of using the filling-modified macromolecular material of gilsonite, relate in particular to and use the byproduct-high softening-point gilsonite that produces in the present petroleum industry, filling-modified application method in commodity polymer material (polystyrene, polypropylene, polyvinyl chloride, Resins, epoxy etc.).Because this method can effectively be utilized a large amount of gilsonite materials that produce in the present petroleum industry, and can reach the purpose of improving the macromolecular material performance and reducing material cost, to optimizing mink cell focus processing process and widening polymeric material field tangible practical significance is arranged.
Background technology
Along with the exhaustion relatively of petroleum resources light component, the mink cell focus processing in the oil refining process is also more and more important, and processing conditions is also harsh all the more.The flux deasphalting method of mink cell focus processing can provide more raw materials for secondary processing, thereby can produce more light-end products, but also make that byproduct---(softening temperature is generally more than 120 ℃ in the softening temperature rising of de-oiled asphalt simultaneously, Eureka bituminous softening temperature is more than 200 ℃), carbon content is more than 80%, ash is very low, hard and crisp under the normal temperature, high temperature is thick semi-fluid down, be not suitable for producing qualified asphaltic products. this moment, the reasonable utilization of this gilsonite has become a great problem that restriction solvent deasphalting processing heavy oil method is used.The purpose of this invention is to make as far as possible this heavy oil upgrading residue resource of gilsonite, utilizes on the derived product of high added value.
Because the present invention preferentially selects for use polystyrene foamed as the major objective modified polymer material, briefly introduce so be necessary it is done: polystyrene (PS) is one of current four big general-purpose plastics, polystyrene series mainly comprises general purpose polystyrene (GPPS), High Impact Polystyrene (HIPS) (HIPS), Expandable Polystyrene (EPS) (EPS) three major types, the yearly capacity of this three major types polystyrene surpasses ten million ton already in the world, for being only second to the third-largest general-purpose plastics of polyethylene and polyvinyl chloride.
EPS (Expanded polystyrene) is the abbreviation of polystyrene foamed.Develop nineteen fifty-two by BASF AG the earliest.It is to adopt polystyrene resin to add whipping agent, carries out thermoplastic simultaneously, produces the foamex of gas, so also claim porous plastics, belongs to Ultra-Light Material.China is at present annual to use about 1,000,000 tons of the consumption of polystyrene foamed, and annual recently usage quantity at least also with 10% speed in rapid increase.Polystyrene foamed has from heavy and light, and the characteristics that heat-proof quality is good are used as wrapping material and lagging material in a large number.Simultaneously because the requirement of China's materials for wall innovation and Regulation of building energy-saving, foamed polystyrene board is used as in composited steel and plastic decking and wall heat insulation material, the road and bridge engineering on a large scale, wherein the over half of output is used in building thermal insulation material and the road and bridge engineering, F1 International Circuit ground, Shanghai ampoule just reaches 60,000 tons, and visible polystyrene foamed has vast market prospect.Because gilsonite is black or Vandyke brown solid, modified foaming polystyrene of the present invention can be used as black material, is mainly used in heat preservation plate material, road and bridge engineering and composited steel and plastic decking, and outstanding two application in the past has broad prospects.
With China's national situation, the EPS material is as a kind of chemical industry product, the problem that the prices of raw and semifnished materials are expensive as facing in order to big area making embankment, engineering cost improves, this makes the EPS material will be subjected to certain limitation in the application of road and bridge engineering, so answer the active development product innovation, reduce cost as far as possible, and the EPS product that the research performance is better, price is more cheap.The EPS market value has broken through 10000 yuan/T at present, if can add the gilsonite class material of 10%-20%, price space wherein is very big.Maximum using and the optimization of the mink cell focus course of processing to China's petrochemical industry resource simultaneously all has positive promoter action.
Summary of the invention
The toughness reinforcing enhancing macromolecular material of rigid particles is meant that to improve the macromolecular material use properties be an effective means by adding inorganic or organic rigid-particle, reaching.If by using gilsonite as organic rigid-particle macromolecular material to be carried out toughness reinforcing processing, its application prospect will be extremely wide.What can solve gilsonite rationally utilizes problem, and a kind of cheapness, natural submicron or nano material that output is big can be provided for the improvement of macromolecular material performance again.The gilsonite material can be in aromatic solvent the spontaneous colloid that is dispersed into, this means gilsonite colloidal nano particle homodisperse in polymer molten masses such as polystyrene at an easy rate.And the homodisperse of ultra-fine grain is the good prerequisite of material property in the macromolecule modified material, also is the gordian technique that is difficult to control on the technology, can effectively be solved by method of the present invention.Research is added this property agent through certain back of handling as effective macromolecular material with inexpensive, the big industry byproduct gilsonite of amount, what can not only solve industry byproduct rationally utilizes problem, can also improve the product performance of commodity polymer material, reduce their production cost, bring tangible economic benefit and social benefit.
The present invention adopts the method for gilsonite and melt polymer material blend to make macromolecular material and gilsonite material reach the purpose of even blend, prepares the goods of desired shape again through granulation, moulding process.And show that by test this method is the truly feasible shock resistance that can effectively improve polystyrene material.
In polystyrene, add 20% gilsonite product after the standard batten that melt blending, injection moulding are made detects as follows through izodtest method (GB/T 1843-1996): 2.59KJ/m
2
100% polystyrene batten: the shock resistance value is 2.59KJ/m
2
20% gilsonite+80% polystyrene batten: the shock resistance value is 3.31KJ/m
2
Detected result shows: the shock resistance of gilsonite polystyrene material has improved more than 25% than pure polystyrene material.Illustrate that thus method of the present invention improves the mechanical property of polystyrene material to a great extent.
