Abstract
The present invention is characterized by that using copolymer polypropylene as matrix resin; changing relative contents of two copolymer polypropylenes which are different in high tenacity and high fluidity; and adding 5-50% (wt%) of barium sulfate ingredient in the presence of ethylene-propylene rubber so as to obtain a kind of filling-modified polypropylene series compounds with high tenacity, high rigidity, high extensibility and high heat resistance. Said invented product can be used as a substitute for ABS, so that it possesses the extensive application field.
Description
The present invention relates to a kind of polypropene composition, specially refer to Inorganic Fillers Filled polypropene composition field.
Because polymer science and processing technology are constantly progressive, utilize the method for alloy, blend and compoundization can make the polypropylene modification of general big kind plastics become inexpensive polypropylene engineering plastics and alloy material thereof, at present in the application of whole world machinery, automobile industry above 1,000,000 tons.
Inorganic filling material is incorporated in the acrylic resin, can improve mixture rigidity, thermotolerance, reduce to shrink and product size stability and can reducing cost significantly.But also can cause material impact toughness, elongation at break obviously to descend.Because the kind difference of mineral filler, they are not quite similar to the influence of composite properties.
For example, talc powder filled polypropylene mixture not only high comprehensive performance but also processing characteristics is fine significantly better than the glass dimension, and can not produce anisotropy.Thereby it is that thermoplastics uses the most general packing material.But talc powder filled polypropylene mixture impelling strength and elongation at break significantly reduce with the increase meeting of talcum powder content.
The performance that a kind of barium sulfate provided by the invention is filled co-polypropylene composition is but obviously different with the talc powder filled polypropylene mixture.The weight percentage of barium sulfate is in the 5-50% scope, the elongation at break of its composition is all greater than 500%, and all presents super high impact toughness, high rigidity, high elongation rate, high heat resistance, and reduced cost, had wide practical use in household electrical appliances, chemical building material and domestic life field.
Modified poly propylene composition of the present invention comprises following component and content:
Composition component weight percentage (%) Co-polypropylene mixture 30-78 toughner 6-16 is through the barium sulfate 4-60 of coupling agent treatment oxidation inhibitor 0.30-0.40 uv-absorbing agent 0.20-0.30 auxiliary agent 0.1-0.20
The MI of described modified poly propylene composition is 3.3-9.5g/10min.
Described Co-polypropylene mixture is the high tenacity Co-polypropylene, melting index (MI)=0.2-2.0g/10min, Izod (breach) shock strength is 360-500J/M and high workability Co-polypropylene, melting index (MI)=19-30g/10min, Izod (breach) shock strength is the mixture of 40-70J/M, and wherein high tenacity Co-polypropylene and high workability Co-polypropylene are 0.5-1.5 by weight.
Described toughner is ethylene propylene rubber (EPR), terpolymer EP rubber (EPDM), ethylene content is 20-70% among the EPR, Mooney viscosity value (ML 1+4,125 ℃) be 20-70, unsaturated diene is that hexadiene, dicyclopentadiene or ethylidene norbornene, its content are 2-8% among the EPDM, ethylene content is 25-70%, and Mooney viscosity value (ML1+4,125 ℃) is 19-70.The adding of 6-16% ethylene-propylene rubber(EPR), help to form an elastic interface layer at filling surface, again because it all has structural compatibility with ethene and propylene, thereby improved mineral filler with the interfacial adhesion state between matrix resin, improved the impelling strength of filled polypropylene effectively, should reduce the consumption of ethylene-propylene rubber(EPR) according to rigidity of material, the harmonious requirement of flexible in actual the use, so not only economy but also can avoid the decline of mechanical property as far as possible.
Described auxiliary agent is a calcium stearate.
For the ease of the dispersion of mineral filler in acrylic resin, improve the consistency of filler with resin, use coupling agent that filler is carried out surface treatment usually, coupling agent commonly used is that organosilicon methane series coupling agent, titanic acid ester are coupling agent or aliphatics metal-salt.What the present invention adopted is metatitanic acid fat system or aliphatics metal-salt coupling agent, and consumption is the 1-3% of barium sulfate.In high-speed mixer, carried out surface treatment 10-20 minute.Coupling agent can directly use also can be made into the coupling agent/acetone soln use of concentration expressed in percentage by weight as 20-50%.Above-mentioned each component was mixed in high-speed mixer 1-2 minute, granulation in twin screw extruder then, the pellet drying dewaters, and makes the standard batten with injection moulding, for mechanics performance determining.
The high filled modified polypropylene composite of barium sulfate of the present invention has superhigh tenacity, high rigidity, high elongation at tear, high heat distortion temperature.
Embodiment 1-6:
With the Co-polypropylene is basestocks, and EPDM (embodiment 6 toughner are EPR) adds 4-50% (weight percentage) BaSO for toughner
4, its blend component, content and performance are listed in the table 1, and the results are shown in Table 2 for mechanics performance determining.
