Abstract
The present invention relates to a high-toughness polypropylene composite material and a preparing process thereof, which belongs to the field of a high-toughness polypropylene composite material modified by inorganic filler. The composite material comprises propene-ethylene copolymerized polypropylene, inorganic rigid particle kaolin, a silane coupling agent and a nonionic surface active agent, wherein the particle diameter of the inorganic rigid particle kaolin is from 0.1 to 20 mu m; the components are uniformly mixed by a high-speed mixer, melted by a double-screw extruder for composite extrusion and then granulated into the high-toughness polypropylene composite material. The notch impact strength of the high-toughness polypropylene composite material can reach 500 J/m, and the high-toughness polypropylene composite material is easy to process at a low cost.
Description
The present invention relates to a kind of modified polypropylene composite material, specially refer to a kind of high-toughness polypropylene composite material with the mineral filler modification.
Usually, in thermoplastics, add intensity and the modulus that inorganic rigid particle can significantly improve matrix material, but cause the reduction of toughness of material simultaneously, perhaps in thermoplastics, add the toughness that rubber-like elasticity physical efficiency significantly improves material, but the rigidity, intensity, thermal distorsion temperature etc. of material are reduced significantly, and cost height simultaneously is in order to remedy the deficiency of above-mentioned two kinds of matrix materials, from 1984, the approach of rubber toughened plastics abroad appearred replacing with inelastic body.
Pay strong and Wang Guiheng at Polym.Int.39 (1993) 309, reported and used surface-treated CaCO
3Toughness reinforcing high density polyethylene(HDPE) has obtained the composite polyethylene material of high tenacity, but can not use surface-treated CaCO
3Tenacity-increased profax obtains high polypropylene composite material of filling high tenacity.
In order to overcome cost height in the above-mentioned prior art, the shortcoming that the modulus of matrix material, tensile strength and thermal distorsion temperature are low the invention provides and adopts surface treated inorganic rigid particle to come filled polypropylene, has obtained a kind of cheap, high filling, the polypropylene composite material of high tenacity.
Technology of the present invention constitute be with the propylene-ethylene Co-polypropylene as matrix, it is inorganic that just the property particle is as weighting agent, silane coupling agent and nonionogenic tenside are as the surface treatment agent of inorganic rigid particle.Its component and proportioning are as follows by weight:
Propylene-ethylene Co-polypropylene 90-40
Inorganic rigid particle 10-60
Silane coupling agent 0.2-1.2
Nonionogenic tenside 2.5-15
Above-mentioned Co-polypropylene is propylene-ethylene atactic copolymerized polypropene or propylene-ethylene block copolymerization polypropylene, above-mentioned inorganic rigid particle is a talcum powder, kaolin, titanium dioxide, silicon-dioxide, lime carbonate, wollastonite or aluminum oxide, its inorganic rigid particle diameter is 0.1-20 μ m, and above-mentioned silane coupling agent is γ-An Jibingjisanyiyangjiguiwan (KH-550), γ-Racemic glycidol oxygen propyl trimethoxy silicane (KH560) or γ-propyl methacrylate base Trimethoxy silane (KH570).Above-mentioned nonionogenic tenside is polyethylene glycol type tensio-active agent such as iso-octyl polyoxyethylene (polymerization degree=4) ethers (OP-4)～iso-octyl polyoxyethylene (polymerization degree=10) ethers (OP-10) or EPE polyol EPE.
The preparation method of high-toughness polypropylene composite material is with above-mentioned inorganic rigid particle 10-60, silane coupling agent 0.2-1.2, after nonionogenic tenside 2.5-15 (weight part) mixes in super mixer, again in twin screw extruder with propylene-ethylene Co-polypropylene 90-40 (weight part) at 170 ℃-230 ℃, form through the compound extruding pelletization of fusion.
Inorganic rigid particle of the present invention can be in propylene-ethylene Co-polypropylene matrix homodisperse, the interface can make the notched Izod impact strength of matrix material bring up to 500J/m in conjunction with good, under the situation of not adding any rubber, can make matrix material reach crisp-tough transformation, and cost is low, easily processing.
