Description
Technical field
The present invention relates to a kind of high bath strength acrylic resin and preparation method thereof.
Background technology
Polypropylene is a kind of widely used general-purpose plastics, and it possesses the performance of many excellences, as little, the tasteless odorless of relative density, anti-edible oil, excellent corrosion resistance, electrical property with chemical stability is good and price is low, output is big, is only second to PVC and PE.But the polypropylene poor toughness, fragile under low temperature disconnected, heat-drawn wire is not high; And polyacrylic chain structure is linear, and under the molten state, polypropylene does not have strain hardening effect, causes the low and refractory of its melt strength shortcomings such as poor performance of hanging down, and therefore limited polyacrylic application greatly.Simultaneously, polyacrylic softening temperature and fusing point are approaching, after temperature is higher than fusing point, the viscosity of its melt strength and melt sharply descends, product wall thickness inequality when causing thermoforming is extruded, is coated with, is occurred when rolling edge curl and shrinks, abscess problem such as subside during extrusion foaming.Therefore, have the polypropylene of strain hardening effect under the exploitation molten state, promptly high melt strength, propylene is imperative.
At present, preparation high melt strength, propylene method mainly is divided into two big classes: a class is that polypropylene and other compounds carry out reaction modifying; Another kind of is that polypropylene and other polymkeric substance carry out blending and modifying.Specific implementation method mainly contains: x ray irradiation x method, reaction extrusion molding, post polymerization still method, solution grafting, dynamic crosslinking method, melt blending modification method etc.
Patent CN1045107A, CN1055372A have set forth and have adopted superoxide initiation grafting modified polypropene powder in polymeric kettle to obtain having the acrylic resin of strain hardening.Another patent (CN1432596A) adopts 2,5 dimethyl-2,5 pair 8 tert-butyl hydroperoxide hexanes and diacrylate-1, the acetone soln mixing of 6-butanediol ester joins twin screw by injection and extrudes in the melt of polypropylene powder, carry out grafting, obtain high bath strength acrylic resin.One piece of open report (Journal of Applied PolymerScience, vol.61,1395～1404,1996) adopts polypropylene and polyfunctional monomer pentaerythritol triacrylate to react in the presence of superoxide can make high melt strength, propylene.Another piece of writing report (Journal ofApplied Polymer Science, vol.66,809～819,1997) adopt polypropylene and polyethylene, trimethylammonium triacrylate under the effect of superoxide, extrude the high melt strength, propylene of preparation branching by twin screw.In addition, adopt acrylic ester monomer in addition under peroxidation, carry out fusion-grafting with polypropylene and can prepare high branched p 0 lypropylene resin (" Chinese plastics ", the 16th volume, the 10th phase, 24～28,2002).From above-mentioned report, as can be seen, in preparation high melt strength, propylene process, all adopt superoxide as initiator.
Chinese patent 200610017181.4 and 200610163256.X adopt original position thermal initiation grafted method to prepare high bath strength acrylic resin, and abandoning tradition uses the method for superoxide initiation grafting prepared in reaction high bath strength acrylic resin.This method has brought good opportunity for the exploitation high bath strength acrylic resin,
Summary of the invention
