Description
Technical field
The invention belongs to the polymer composite field.Be particularly related to polyurethane elastomer/laminated nano composition and preparation method thereof, be mainly used in the laying of sports field.
Background technology
About the laying of sports field, a race track was at first laid with polyurethane material by Minnesota Mining and Manufacturing Company in 1961; The urethane surfacing material that nineteen sixty-eight 19 Olympic Games, stadium runway formally adopt 3M company to produce is laid (being called " tower when " (Tartan) runway), now by internationally recognized be best competition area, and generally adopted.The last century the eighties, the stadium runway with the urethane laying has also appearred in China.All continuing to use over more than twenty year and being similar to the Chinese invention patent application publication number is the formula system that CN1033639A adopted, that is: so-called TDI (tolylene diisocyanate) (A component) and MOCA (3,3 '-two chloro-4,4 '-diaminodiphenylmethane) (B component) system.Performance is up to state standards (GB/T14833-93) (with reference to table 1) reluctantly.
1), only be 105% because of the main mechanical mechanics property of product, as elongation at break the several of main problems that this formula system exists is:, can not adapt to sports field because of generations such as frozen ground, the water logging bases stress that deformation produced such as rupture, swell, subside, cause the fracture of urethane paver; 2), the flame retardant properties of product is lower, in fact, the flame retardant properties of domestic most of products does not all reach fire-retardant primary standard at present; 3), for anti-aging, mildew-resistant, added anti UV agent, antioxidant and the mould inhibitor of multiple pricing costliness, improved cost greatly, but add-on reaches actual requirement again far away, effect is unsatisfactory.Therefore, in order to overcome the above problems, mechanical mechanics property, flame retardant properties and the anti-aging of raising urethane paver, mildew-resistant sex change energy etc. are necessary to consider synthesizing from newly carrying out molecular designing and formula adjustment and using of the new technology the excellent more sports field paver of obtained performance polyurethane elastomer.
On " polymer journal " the 3rd phase in June calendar year 2001, delivered the paper " synthetic, the structure of composite polyurethane elastomer/montmorillonoid nano-material and performance " at engineering plastics National Key Laboratory of Institute of Chemistry, Academia Sinica molecular science center, only report with regard to breadboard experiment situation, do not relate to practical engineering application at all, more do not relate to organise hydrotalcite as stratified nano materials in polyurethane elastomer/laminated nano composition application and as the application of sports field paver.
Summary of the invention
Purpose of the present invention just is to solve as above problem, provide a kind of sports field paver and manufacture method thereof novel, that performance is excellent more, i.e. polyurethane elastomer/laminated nano composition, the especially polyurethane elastomer/hydrotalcite laminated nano composition sports field that organises paver and preparation method thereof.
The present inventor attempts the mechanical property that the applying nano materials new technology strengthens polyurethane elastomer.Common ultra-fine granular nano material such as silicon-dioxide, titanium dioxide etc. were used in test once.But it is when mixing,, more outstanding because the effect of the powerful Van der Waals between nano molecular " agglomeration ", especially inorganic nano material takes place in organic phase with the elastomeric high polymer monomer of synthesis of polyurethane.Can't show the small-size effect of nano molecular etc., also just can't reach enhancement to former polyurethane elastomer mechanical property, even with organic molecule ultra-fine granular nano material such as silicon-dioxide etc. are given " coating " in advance, effect is also very little, does not have the substantive phenomenon that strengthens.
Test by analysis, the present invention has selected the polynite of inorganic laminated nano material such as silico-aluminate or the hydrotalcite of Mg aluminate for use, effectively organise handle after, can avoid the agglomeration of nano material, thereby can show all manifold effects of nano material, reach the effect that strengthens the polyurethane elastomer mechanical property.Polynite (MMT) has basic character, its basic structural unit is natural nano silicate lamella, each layer constitutes by containing an alumina octahedral in two silicon-oxy tetrahedrons, about 1 nanometer of interlamellar spacing size, about 100 nanometers of length and width, the residual negative electric charge on the lamella is by positively charged ion that is positioned at interlayer such as cation balances such as Na+, Ca++.Available like this organic cation carries out ion exchange reaction and generates organic montmorillonoid (OMMT).And hydrotalcite (LDHs) has acidic character, become monolithic layer by the octahedra shared prismatic of magnesia, the interlamellar spacing size is about 20～60 nanometers, the magnesium ion (Mg++) that is positioned on the layer can be made laminate have positive charge by aluminum ion (Al+++) isomorphous substitution within the specific limits, and the positive charge balance on tradable negatively charged ion and the laminate is arranged between laminate.Therefore, available organic anion is carried out ion exchange reaction and is generated the hydrotalcite (OLDHs) that organises.
The present invention makes full use of the intercalation compounding technology to this inorganic laminated nano material, insert different stratified nano materials with different objects after, can assemble the stratified nano materials that organises with different performance.They carry out macromolecular polymerization reaction after fusing with the organic molecule monomer of forming urethane again, have obtained the enhancing polyurethane elastomer.The sports field of laying with the polyurethane elastomer/laminated nano composition of this technology preparation has higher mechanical mechanics property and fire-retardant, anti-mold effect.
After organic molecule carries out intercalation to the laminated structure nano material, general organic molecule has to a certain degree winding effect to the main body flaggy, this effect comes down to organising to inorganic lamellar material, and degree that organises and effect can be decided with object kind quantity, therefore use different stratified nano materials, select different intercalation objects can obtain the ideal interfacial effect, and the latter's enhancing is the key that the macromolecular material mechanical property improves.Stratified nano materials has the obstructing capacity to the micromolecular compound migration, can avoid as the molecular migration of the used softening agent of polyurethane elastomer/laminated nano composition involved in the present invention.(promptly preventing " oil impregnate " phenomenon of above-mentioned materials).Because the good combination of polyurethane elastomer and stratified nano materials by the planar orientation of laminar nano, makes it polyurethane elastomer/laminated nano composition and shows good dimensional stability, barrier, thereby has fire-retardant self-gravitation.The special construction of the matrix material of this polymer and laminar nano has significant inhibitory effect to multiple microorganism and fungus grown, has antimildew function.
Secondly, in the urethane polymerization reaction process, the acid-basicity of medium is bigger to the speed of response influence, especially being used for different sport fields ground under different weathers lays, more to select different acid-basicity stratified nano materials, show weakly alkaline as organic montmorillonoid, but accelerated reaction speed.On the contrary, the hydrotalcite that organises is slightly acidic, can reduce speed of response.In like manner, also can be influential as the acid-basicity of the stopping composition in the polyurethane elastomer/laminated nano composition to polymerization rate.Especially under the condition of the polymerization reaction system medium viscosity thickening that stratified nano materials is arranged, do not wish that too fast speed of response (especially when the hot weather construction surface temperature is higher) more do not wish to use weakly alkaline talcum powder, so select weakly acidic potter's clay for use.And the latter to the reinforcement of elastic polyurethane/laminated nano composition fruit also be better than the former.
