Abstract
The present invention relates to a high molecular material and particularly relates to a casting material of polyurethane elastomer for paving universal ground surfaces. In the present invention, the new monomers of polytetrahydrofuran diol and tetrahydrofuran-propylene oxide copolymer diol are introduced for the polymerization reaction with diisocyanate, and a crosslinking agent, a filling agent and a catalyst system are newly designed so as to obtain the casting material of polyurethane elastomer for paving the universal ground surfaces with universality, high strength and low temperature resistance.
Description
Technical field
The present invention relates to macromolecular material, particularly mould material is laid in the polyurethane elastomer place.
Background technology
Along with China's economy develops rapidly, the laying that mould material has been widely used in electronic machine, household electrical appliances, IT product manufacturing shop and warehouse, outdoor sport place, space for activities, kindergarten etc. is laid in the polyurethane elastomer place, the use region is vast, the purposes variation, thereby, the place paver has been proposed new requirement.High-strength mechanical properties if can be still kept at low temperatures, the stronger paver of snappiness, high rigidity, mechanical mechanics property that the gravity forklift rolls can be stood in place, above-mentioned warehouse.Present widespread usage is the material polymerization system that CN1033639A adopted just like the Chinese invention patent application publication number, i.e. TDI (tolylene diisocyanate)-PPG (hydroxyl polyoxytrimethylene ether) system.The subject matter of this material be under the normal temperature condition main mechanical mechanics property, be 105% only as elongation at break, (GB/T14833-93) reluctantly is up to state standards.And at low temperatures, as at-20 ℃--more show as easy embrittlement in the time of 30 ℃, have through one or two severe winter, the place is with regard to many places embrittlement, disconnection and can't use, and lets alone can stand the gravity forklift and roll required mechanics of machinery intensity.
Summary of the invention
Purpose of the present invention just is to address the above problem, and has introduced polytetrahydrofuran diol (PTMG) and tetrahydrofuran (THF)-propylene oxide copolymerization glycol (PTPG) new monomer and vulcabond polyreaction.In new molecular designing, also draw as having gone into the stronger diisocyanate monomer MDI-50 of rigidity; Thereby obtain low temperature resistantly, promptly keep required mechanics of machinery intensity at low temperatures, and have macromolecular material higher, more excellent mechanical property than TDI-PPG system polymer at normal temperatures.
Have side group different with PPG, the urethane that polytetrahydrofuran diol (PTMG) forms does not have side group at soft chain segment.Because the steric hindrance of side group, a little less than the hydrogen bond, crystallinity is poor, and the mechanical mechanics property of the polyurethane elastomer of its formation has better mechanical mechanics property with regard to the polyurethane elastomer that forms not as PTMG, as: stronger, more pliable and tougher, more low temperature resistant, more wear-resisting, hydrolysis etc. more.
The low price of tetrahydrofuran (THF)-propylene oxide copolymerization glycol, and the approximate polytetrahydrofuran diol goods of its product properties, resisting cold to reach-200 ℃
In molecular designing of the present invention, fully take into account the snappiness that increases molecule, anti-fragility, in linking agent, added and made the more flexible Viscotrol C of molecule.Consider the ease for operation of floor file construction, enough reinforcement should be arranged, its viscosity is also wanted appropriateness simultaneously, for it is controlled at 10, below the 000mPas, and has used kaolin-talcum powder casting resin mixture.The catalyzer that uses has been considered the ease for operation of construction too, makes real-world effectiveness be arranged an inductive phase, prolong storage period (Pot-life).After the place laying was finished, the elastic polyurethane physical efficiency is curing molding soon, has adopted nontoxic composite catalyst system, i.e. isocaprylic acid zinc-isocaprylic acid or stannous octoate-isocaprylic acid system.
The place paver of the polyurethane elastomer of the present invention's first scheme is, form through chain extension-crosslinking reaction by giving aggressiveness (A component) and chain extension-crosslinking agent (B component) and catalyzer, wherein: give polyether glycol that aggressiveness (A component) uses and introduced polytetrahydrofuran diol or tetrahydrofuran (THF)-propylene oxide copolymerization glycol and vulcabond TDI (tolylene diisocyanate) or MDI-50 (4.4 '-two isocyanato ditanes and 2.4 '-two isocyanato ditane mixtures) and react and get; And the chainextender that chain extension-crosslinking agent (B component) is used has also added dihydroxyl polyethenoxy ether (N220 molecular weight 2000) except MOCA (3.3 '-two chloro-4.4 '-diaminodiphenylmethane), linking agent is except adding trihydroxy-polyoxytrimethylene ether (N330, molecular weight 3000) also added Viscotrol C outside, softening agent is phthalic acid two 2-ethylhexoates (DOP) or clorafin.
The place paver of the polyurethane elastomer of alternative plan of the present invention is, what use in the auxiliary material of above-mentioned B component is kaolin-talcum powder (1: 2) mixed reinforcing agent, and catalyzer is nontoxic isocaprylic acid zinc-isocaprylic acid (2: 1) or stannous octoate-isocaprylic acid (2: 1) mixed system.The mill base material that the B component adds is Fe
