Description
The invention belongs to polymer processing field.
Along with the widespread use with plastics of developing rapidly of plastics industry, the filling-modified technology of plastics obtains people's attention day by day.In polymkeric substance, pass through to add various mineral filler composite moldings, not only can reduce the cost of goods greatly, and can significantly improve some performances of plastics, as mechanical property, thermal characteristics, electrical property, wear resisting property and ageing-resistant performance, thereby give material new characteristic, to satisfy the needs of different purposes.
The traditional method of modifying plastics, normally adopt direct blended method to join employed filler and auxiliary agent and carry out forming process in the matrix resin again, the characteristics of this method are simple and easy to do, but because commercially available matrix resin raw material great majority all are granular, facts have proved, because the volume difference is big, density differs greatly, various pulverulent filler are difficult to mix with particulate resins.The filling master batch method that grows up subsequently can obtain the moulded products of component homogeneous as a rule than traditional method, can make also that forming process is stable carries out, and is the filling-modified a kind of effective ways of plastics.
So-called filling master batch method is exactly that the filler component and the vector resin that will will add carries out the mixed milling granulation earlier, makes the particle close with the matrix resin volume.The concentration of filler will exceed the several times to tens times of actual needed this concentration of component in filling master batch.When filling master batch by a certain percentage with after matrix resin cooperates, this component just can be diluted to predetermined concentration in matrix resin in molding process.
Polyolefin packing material comprises vector resin, filler and auxiliary agent three parts.Vector resin is selected nonpolar polyolefin hydro carbons materials such as polyethylene, polypropylene usually, and filler is often selected lime carbonate, the mineral filler of talcum powder isopolarity for use, and therefore consistency between the two is poor, and the interface is difficult to form good bonding.Combine with the interface of mineral filler in order to improve vector resin, make to form the good interface clinging power between vector resin and the mineral filler, must adopt appropriate means that inorganic filler surface is carried out modification and handle.
The filling master batch technology of preparing of prior art, in the preparation process of filling master batch, filler adopts coupling agent to carry out surface modification more, coupling agent commonly used mainly contains silane coupling agent, titanate coupling agent and aluminate coupling agent (Polymer Engineering and Science, 1984,24 (18): 1369-1382).Usually contain a few class character group different in the molecule of coupling agent, its objective is the consistency of improving between filler and the polymkeric substance, thereby strengthen the interfacial interaction of filling compound system with effect.In addition, also can adopt the polymer overmold technology that filler is carried out surface modification (Journal of Material Science, 1988, (23): 535), bisphenol A type epoxy resin and aminimide linking agent that this method employing molecular weight is 340-630 are dissolved in the ethanol, add an amount of mica, after certain hour stirs, obtain the active filler that epoxy prepolymer and linking agent coat.In order to improve filling-modified effect, except filling surface is handled, also can carry out modification to matrix resin, as graft acrylic acid or maleic anhydride etc. on polyolefin backbone, also can make filling-modified effect significantly increase (external plastics, 1991,9 (2): 38-41).
More than several inorganic filler surface is carried out the methods that modification is handled, can improve vector resin to a certain extent combines with the interface of mineral filler, the preparation process that is used for filling master batch, but preparation cost is higher, complex procedures, the filling master batch of preparation is limited to the modified effect of matrix resin, particularly filling master batch can obviously reduce the shock resistance of matrix resin when content is high in matrix resin.
Purpose of the present invention discloses a kind of vector resin that can obviously improve at the deficiency of the existing technology of preparing of polyolefin packing material and combines with the interface of mineral filler, filler is homodisperse in vector resin, can significantly improve performances such as matrix resin resistance to impact shock, and preparation cost is low, simple a kind of polyolefin packing material of processing and preparing and preparation for processing thereof.
Main points of the present invention are to increase acidic functionality monomer and initiator in filler and vector resin, make filler and vector resin under acidic functionality monomer and action of evocating, extrude by the twin screw extruder reaction, the acidic functionality monomer is when fusion-grafting arrives the vector resin molecular chain, by surface infiltration and chemical bonding compatibilization filler and vector resin on the spot, make and form the good interface clinging power between vector resin and the mineral filler, make that uniform filling is scattered in the vector resin in the filling master batch, when the high-content filling master batch is used for matrix resin, can significantly improve resistance to impact shock and other performance of matrix resin.It is simple to adopt reactive working method to prepare polyolefin packing material, remarkable in economical benefits.
At the polyolefin packing material of foregoing invention purpose preparation, its basal component comprises (a) polyolefins vector resin, (b) filler, (c) acidic functionality monomer, (d) initiator, (e) dispersion agent.The weight percent of each component in filling master batch is:
(a) the polyolefins vector resin 13～31%;
(b) filler 68～85%;
(c) the acidic functionality monomer 0.35～1.75%;
(d) initiator 0.04～0.35%;
(e) dispersion agent 0.40～3.40%.
The polyolefins vector resin is the matrix of filling master batch among the present invention, mainly filler is played coating, bonding effect, makes the filling master batch granulating and has certain intensity.In the present invention, the polyolefins vector resin also will be under action of evocating and acidic functionality monomer generation melting graft reaction except having above effect.Polyolefins vector resin commonly used comprises polyethylene, polypropylene, ethylene/propene binary second third glue (EPR), ethylene-propylene diene copolymer (EPDM) and ethylene/octene (POE).More than in several resins, remove polypropylene and molecular rupture takes place during with acidic functionality monomer generation melting graft reaction under the initiator effect because of the tertiary carbon atom that contains in the molecular structure, cause that molecular weight reduces, can improve outside the flowability of filling master batch, other resin causes the mobile variation of filling master batch because of molecular chain generation part crosslinking reaction under the initiator effect, but little crosslinking structure that crosslinking reaction causes helps to improve shock strength and other performance of filling matrix resin again.
Filler among the present invention mainly is mineral filler, as lime carbonate, talcum powder and barium sulfate etc.Can obviously improve the performances such as modulus in flexure, heat resisting temperature and molding shrinkage of matrix resin with the Inorganic Fillers Filled matrix resin.Absorb airborne moisture because inorganic filler surface contains polar group easily, therefore before using mineral filler, mineral filler must be carried out drying treatment, as adopting oven for drying or directly adopting high-speed mixer to dry while mixing.
The acidic functionality monomer that adopts among the present invention is selected from carboxylic acid and acid anhydrides, as methacrylic acid, vinylformic acid and maleic anhydride.Vector resin and acidic functionality monomer are under action of evocating, generate living radical, the reaction of generation free radical grafting, acidic functionality is monomer-grafted to the molecular chain of vector resin, make vector resin by the nonpolar polarity that becomes, be grafted to simultaneously on the vector resin molecular chain the molecule that contains acidic functionality can with the polar group generation surface infiltration and the chemical bonding effect on filler top layer, make the good phase interface bounding force of formation between vector resin and the mineral filler, played the coupled action and the polymer overmold technology of coupling agent and filler has been carried out the effect of surface modification, with earlier on polyolefin backbone graft acrylic acid or maleic anhydride prepare compatilizer and add the method for improving filling-modified effect in the mineral filler again to and compare, the method applied in the present invention is simple to operate, and modified effect is obvious.
