Abstract
A three-element composition is prepared from polypropene (PP) (72-91 wt%), POE or MPOE (1-13) and BaSO4 (7-20) through mixing, stirring, kneading and extruding out. Its advantages are high impact strength, high toughness, high P/C ratio, high resistance to thermal or ultraviolet ageing, and low cost.
Description
Technical field the present invention relates to a kind of polypropylene/elastomer/inorganic particulate trielement composite material and preparation method thereof.
Background technology
Since the eighties, people use elastomerics and inorganic particulate simultaneously in polypropylene (PP) modification, form PP/ elastomerics/inorganic particulate three-component compound system., in the hope of obtaining having concurrently toughness and inflexible matrix material.Elastomerics commonly used has: EPM, EPDM, SBS.Result of study shows: have only elastomeric content just to be greatly increased in 20% shock strength when above in these compound systems.This has just reduced performance of composites/price ratio.CaCO in the inorganic particulate
3BaSO
4PP is had toughening effect, but this toughening effect only can embody just when their addition is big.This brings negative impact just for the processing characteristics and the use properties of the finished product.
Summary of the invention
The purpose of this invention is to provide a kind of novel polypropylene/elastomer/inorganic particulate trielement composite material and preparation method thereof.Consumption is few, toughness reinforcing, reinforced effects is good for its filler (elastomerics and inorganic particulate), has higher over-all properties and P/C ratio, thereby overcomes the above-mentioned shortcoming that prior art exists.
The present invention is by selecting suitable elastomerics and inorganic particulate as filler, reaches under the little prerequisite of modulus and loss of intensity, and the toughness of PP is greatly increased.
Polypropylene composite material of the present invention is by polypropylene (PP), ethene-1-octene copolymer (polyoctene-ethylene is called for short POE) or form through POE of modified by maleic acid anhydride graft (MPOE) and barium sulfate.The content of each composition is by weight percentage: polypropylene 72-91 (being preferably 80-87), POE or MPOE 1-13 (being preferably 2-9), barium sulfate 7-20 (being preferably 10-12).
The maleic anhydride graft amount of the MPOE that the polypropylene composite material of the invention described above is used is generally 0.55-2.5%wt.
Used barium sulfate is process white preferably.
Also can in PP, add polypropylene (MPP), also can obtain good toughness reinforcing reinforced effects through modified by maleic acid anhydride graft.The MPP consumption is generally the 2-15%wt of polypropylene total amount (PP+MPP).
The preparation method of enhancing of the present invention, toughened polypropylene composite is:
(1), the preparation of tertiary blending system pre-composition: with PP or PP and MPP, and POE or MPOE add in the homogenizer together, stirred 3-10 minute, and then add barium sulfate, continues stirring 3-10 minute, obtains pre-composition by required proportioning;
Preferably barium sulfate was handled through 350-450 ℃ of retort furnace calcining in advance in 4-7 hour, to remove organic pollutant and production process residual surfactant.Used barium sulfate is process white preferably.
(2), the preparation of trielement composite material: with above-mentioned pre-composition put into conventional device of plastic processing (as single screw extrusion machine, twin screw extruder, Banbury mixer or two roller mills etc.) through mediate, mixing, extrude, granulation and make required toughness reinforcing, Reinforced Polypropylene trielement composite material.
The present invention is owing to select POE and BaSO for use
4Be filler, make this ternary complex tie up to rigidity and increase or change under the little prerequisite that shock strength improves a lot, and has reached the rigidity and the better balance of flexible of material; And can be issued to toughness reinforcing reinforced effects preferably in the situation of less elastomer content; This just helps improving the cost performance of material.Because POE does not contain unsaturated double-bond, make the matrix material that makes that the aging and anti-ultraviolet aging performance of better heat-resisting be arranged simultaneously, be suitable for outdoor use.Moreover POE itself is particulate state, can be directly and the PP blend, and make process operation easy, thereby reduce production costs.

Table 2 is the result show: (1) BaSO
4, three kinds of components of POE, MPOE all play the heterogeneous nucleation effect to PP, make PP under comparatively high temps, begin crystallization, and with the increase of nucleation component, PP crystallization initiation temperature T initial sum peak crystallization temperature T the most mostly shift to pyritous trend, present nucleation density and strengthen, nucleogenesis is strengthened.This heterogeneous nucleation effect causes optimizing the mechanical property of material.(2) at PP/POE/BaSO
4After adding a spot of MPP in the three-component compound system crystallization initiation temperature is further improved, this shows has strengthened the interfacial interaction between them and has improved nucleogenesis after adding MPP.But further improve MPP content and adverse influence will be arranged the crystallization behavior of system.So the add-on of MPP is wanted suitably.
