Description
Technical field
The invention belongs to thermoplastics modification field, be specifically related to a kind of high-performance, low original position increase-volume PO/PS Alloy And Preparation Method and application of shrinking.
Background technology
Polyolefine (PO) general-purpose plastics like PP, HDPE, LDPE, LLDPE etc., has excellent comprehensive performances, good chemicalstability, moulding processability and cheap price preferably; But it also exists shortcomings such as intensity difference, modulus is low, hardness is low, and molding shrinkage is big.Compare with PO, PS has higher hardness and low shrinking percentage, and printing is good, but PS environmental stress crack resistance, toughness and solvent resistance are relatively poor.In order to obtain the material of high comprehensive performance, people carry out study on the modification to PO and PS, attempt to prepare the polyblend that both premium propertiess are integrated in one.
As everyone knows, PO and PS are typical incompatible systems, if with they direct blend, serious being separated will take place, cause intermingling material to rupture easily, and mechanical property is very poor, lack use value.Therefore solving consistency and the interface adhesion between PO and the PS, is the key of the good PO/PS alloy of processability.Chinese scholars adopts physics and chemical process that the blending and modifying of PO and PS has been done number of research projects, and wherein a kind of method commonly used is to add compatilizer.Be generally the block or the graft copolymer of two kinds of uncompatibility homopolymer, like SBS, SEBS, SIS, SEPS, PP-MAH, PE-MAH, PS-g-PP, PS-g-PE etc.When block or graftomer existed on compatible interface neither, it can reach the emulsifying agent effect, and reduces IT, thereby improves PO and PS consistency mutually.In relevant research, find; When segmented copolymers such as adding SBS, SEBS, SIS, SEPS are made expanding material; Addition will reach more than the 10phr at least just can reach compatibilization effect preferably, and this type of expanding material of too much adding can make the mechanical property of alloy, and especially intensity and modulus descend serious; When graftss such as adding PP-MAH, PS-g-PE, PS-g-PP were made expanding material, though compatibilization effect is remarkable, it was synthetic difficult, and cost is higher, is difficult to be applied in the suitability for industrialized production.
Another kind method is to add reactive compatibilizer; Through itself having the polymkeric substance of active reactive group; Perhaps add small molecules initiator etc.; Make between the blend component chemical reaction takes place, thereby generation grafting or segmented copolymer reach the purpose to the increase-volume of incompatible blend original position as expanding material.In the PS/ polyolefin blends, introduce functional group and carry out reactive compatibilization, its compatibilization effect is fairly obvious.But, in order to introduce normally relatively more expensive reagent or the special multipolymer of structure that reactive functional groups is selected for use.Though compare with non-reactive compatibilizer, its consumption is very little, uses in industrial production but limited it to a certain extent.Therefore, develop a kind of not only effectively but also cheaply PO/PS alloy compatibilizing method have important practical significance.
