Description
Technical field
The invention belongs to polymer composite, particularly sports place wearing layer material (nano-polyurethane particle) for preparing by the polyurethane/nano polynite and preparation method thereof.
Background technology
Polyurethane particles is because of its high-wearing feature, and snappiness is still the optimal selection of the world, domestic sports field (track and field runway) pavement material.What the existing sports field of China was used is urethane pellet glue (common name A component) and the two component prescriptions of solidifying agent (common name B component), the cast room temperature forming.So far, each manufacturer production of China is as the prescription of the conventional polyurethanes pellet glue of sports field wearing layer material, and all continuing to use the Chinese invention patent publication number is the disclosed TDI-MOCA system of C N 1033639A, and the fair of product only can be up to state standards.This prescription is by the practice of recent two decades, expose a lot of defectives, low as the polyurethane elastomer mechanical property, especially manufacturing firm increases the stopping composition content that forms in the polyurethane elastomer B component greatly for reducing production costs, further aggravated the decline of polyurethane elastomer mechanical property thus, wear no resistance, bonding force is bad, and its result is easier to cause the sports field nature threshing of being mated formation by this polyurethane elastomer, not wear-resisting, shorten dramatically work-ing life.
Summary of the invention
One of purpose of the present invention provides the sports place wearing layer material (nano-polyurethane particle) by polyurethane/nano polynite preparation, in order to improve polyurethane elastomer mechanical property and wear resistance, prolongs its work-ing life.
Another object of the present invention provides the sports place wearing layer preparation methods by polyurethane/nano polynite preparation.
The object of the present invention is achieved like this:
Sports place wearing layer material by polyurethane/nano polynite preparation is made up of elastomerics A component, B component and 2-ethylhexoate catalyzer; Wherein, the weight ratio of A component and B component is 1: 2～1: 4 in the polyurethane/nano polynite, and the 2-ethylhexoate catalyst consumption is 3～7wt% of A component and B component weight summation;
The composition of A component and weight percent are:

Described polyether-tribasic alcohol comprises glycerol polyoxy third rare ether, and its molecular weight is 3000; Described polyether Glycols comprises propylene glycol polyoxy third rare ether, and its molecular weight is 400～2000; Chlorinated paraffin oil and talcum powder are technical grades; Silicon-dioxide is gas phase or precipitated silica; Described 2-ethylhexoate comprises calcium iso-octoate or isocaprylic acid zinc etc.
Sports field wearing layer preparation methods by polyurethane/nano polynite preparation of the present invention is that the step of this method comprises by weight percentage:
(1), A component preparation: will join in the reactor based on the polyether Glycols 67～78% of A component total amount, stir down at 80～100 ℃, vacuumize the dehydration degassing 2～3 hours, be cooled to 40～60 ℃, add tolylene diisocyanate 22～32%, 70～90 ℃ of down reactions 2～3 hours, it is standby to be cooled to room temperature;
(2), B component preparation: will join in the reactor with polyether-tribasic alcohol 15～30% based on the nano imvite 1～5% of B component total amount and mix, under 50～60 ℃, vacuumize the dehydration degassing 1～3 hour, sneak into 3 again, 3 '-two chloro-4,4 '-diaminodiphenyl-methane 4～8%, talcum powder 28～38%, silicon dioxide powder 1～3%, iron oxide red or lemon yellow-phthalocyanine green mixture 2～4% and chlorinated paraffinic oil 25～35% mix under 80 ℃～90 ℃, vacuumizing the dehydration degassing 1～2 hour, it is standby to be cooled to room temperature;
(3), nano-polyurethane particulate preparation: by the A component in the polyurethane/nano polynite and the weight ratio of B component is to mix A and B component in 1: 2～1: 4, mix the back add-on and be 3～7% 2-ethylhexoate catalyzer of A and B component weight sum total, stir, polymerizing curable, prepare the nano-polyurethane elastomerics offset plate that paving material for sports field is used, through 7～14 days wear out, carry out particle processing again, grain diameter is 2～4.5mm.
The used polynite of the present invention can be buied from market, and nano imvite can obtain with following preparation method: polynite 5% (W/W) aqueous solution, and its cation exchange capacity CEC9～10mmol/g meter, stirring reaction 1 hour, suction strainer is washed to no Cl
-(AgNO
3Detect), oven dry, pulverizing.
The used polynite of the present invention is a kind of layered silicate, about 1 nanometer of its structure lamella (1nm).One alumina octahedral subgrade is arranged in its laminate structure, and it is connected by shared Sauerstoffatom with the subgrade of two silicon-oxy tetrahedrons therein, because the aluminium atom of the alumina layer of intermediate course is by the low price ion, as Na
+, Ca
++Deng replacement, lamella thereby negative charge is arranged exchanges with alkyl quaternary ammonium salts or other organic cations easily, the generation organic montmorillonoid, thereby have lipophilicity.So, it can mix with the organic polymer monomer, also may enter by the interlayer that enlarges because of the alkyl quaternary ammonium salts exchange by monomer.Carry out macromolecular polymerization reaction, it not only has the nano effect that nano-scale provides (as high surface energy etc.), and polymer molecule exists in the structure lamella, like this crystalline structure to the organic macromolecule mechanical property contribution can not ignore.
When the present invention changes the prescription of conventional urethane elastomerics sports field wearing layer again, adopt the nano imvite compounding technology emphatically, the mechanical property of sports field wearing layer is greatly strengthened, and tensile strength amplification is more than 20%, and elongation at break amplification is more than 30～40%.Improved the quality of mating formation of sports field greatly, obtained prolongation work-ing life, and be further to improve prescription, the aspect that reduces production costs provides may.
Below in conjunction with embodiment technical scheme of the present invention is further described.
