Abstract
The invention discloses a high-strength nanocomposite. The high-strength nanocomposite is prepared from, by weight, 33-37 parts of ultra-high molecular weight polyethylene, 20-26 parts of Na-montmorillonite, 15-21 parts of cation exchanger, 14-20 parts of maleic anhydride, 11-15 parts of initiating agent and 2-3 parts of dispersing agent. By means of the high-strength nanocomposite, hydrophilic montmorillonite can be changed to be good in lipophilicity, the comprehensive capacity with an ultra-high molecular weight polyethylene substrate is improved, the compatibility between the organic montmorillonite and the ultra-high molecular weight polyethylene is improved, the flowing property of the ultra-high molecular weight polyethylene is improved, and meanwhile tensile strength and the impact strength are improved.
Description
Technical field
The present invention relates to field of compound material, particularly relate to a kind of high-strength nano matrix material.
Background technology
Ultrahigh molecular weight polyethylene(UHMWPE) more than to be a kind of viscosity-average molecular weight play 150, have the thermoplastic engineering plastic of excellent properties, it has common polythene and incomparable wear resistance, shock-resistance and the resistance to low temperature of other engineering plastics.But because its molecular chain height tangles, cause difficulty of processing very big.Polynite is the typical lamellar silicate material that a class interlayer has exchangable ion, is the important materials of preparation nano composite material.But the preparation of its related compound material but rarely has report, and related work at home carry out few.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of high-strength nano matrix material is provided, meets the primary demand in market.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of high-strength nano matrix material, counts by weight, comprises the ultrahigh molecular weight polyethylene(UHMWPE) of 33 ~ 37 parts, the sodium-based montmorillonite of 20 ~ 26 parts, the cationite of 15 ~ 21 parts, the maleic anhydride of 14 ~ 20 parts, the initiator of 11 ~ 15 parts, the dispersion agent of 2 ~ 3 parts.
Further, described initiator is the acetone soln of dicumyl peroxide.
Further, described dispersion agent is stearic acid.
Further, described composite material and preparation method thereof comprises the following steps: by ultrahigh molecular weight polyethylene(UHMWPE) preheating certain hour under fusing point, add maleic anhydride, initiator and dispersion agent successively, at 120 DEG C of temperature, ball milling terminates reaction after 3 hours, carry out drying with after washing with acetone again, obtain modified ultra-high molecular weight polyethylene; By sodium-based montmorillonite in distilled water in 90 DEG C of stirrings, drip cationite, filter after 2 hours, washing, dry be also milled to powder, obtain organo montmorillonite; After modified ultra-high molecular weight polyethylene is mixed in high-speed mixer with organo montmorillonite, extrusion moulding in an extruder.
Further, add micro-interfacial agents p-Xylol after described ultrahigh molecular weight polyethylene(UHMWPE) preheating at once and fully merge.
The invention has the beneficial effects as follows:
Material of the present invention can make polynite be become from wetting ability to have good lipophilicity, improve the integration capability with ultrahigh molecular weight polyethylene(UHMWPE) matrix, improve the consistency between organo montmorillonite and ultrahigh molecular weight polyethylene(UHMWPE), add the flowing property of ultrahigh molecular weight polyethylene(UHMWPE), also improve its tensile strength and shock strength simultaneously.
