Abstract
The present invention discloses an environment-protecting type polyurethane paving material for sports fields, which is composed of a component A, a component B and black latex particles. Without high-toxicity tolylene diisocyanate and heavy metal catalysts, the environment-protecting type polyurethane paving material for sports fields solves the environmental pollution problem existing in the production, the construction and the application of the material for more than thirty years and the problem of harm to the material to human bodies, and contributes to people's health and the development of 'green Olympic games'.
Description
Technical field
The present invention relates to a kind of sport field environment-friendly type surfacing material, particularly a kind ofly do not contain highly toxic tolylene diisocyanate, do not contain the environment-friendly type sport field surfacing material of heavy metal catalyst.
Background technology
Urethanes playground (abbreviation plastic sports ground) has good wear-resisting, oil resistant, Weather-resistant, elasticity is suitable, shock-absorbing performance is good, durometer level is wide, smooth, anti-skidding, color is attractive in appearance and be not subjected to advantage such as weather influence, popular deeply, also be the developing direction that modern physical culture athletic ground (polyurethane plastic runway, plastic net court, plastic cement basketball court, plastic cement court, plastic cement table tennis court etc.) is built.
But for a long time, in it is produced, need to use tolylene diisocyanate (TDI has two kinds of isomer), and TDI is the noxious chemical of easily bringing into play, easy and protein bound, the TDI steam that sucks high density can cause bronchitis, pneumonia and pulmonary edema; After the Long contact time, also can cause hepatic disease; Contact liq can cause skin and eyes permanent damage.Its LD
50(mouth is gone into mld) is 5.8g/kg, and TLV (toxic reaction liminal value) is 0.14mg/m
3, maximum allowable concentration 0.2mg/m in workshop air
3(health ministerial standard TJ36-79).
In addition, in its construction, need to add the drying that lead drier quickens urethane, and improve its performance.According to estimates, calendar year 2001 whole nation plastic sports ground (containing plastic cement race track, plastic cement basketball court, plastic net court etc.) is laid about 7,000,000 m of area
2, about 4,480,000 Kg of required lead drier, the per kilogram lead tolerance is 1340mg in the plastic cement move materials that is equivalent to lay.And lead is a kind of cumulative toxicant, has perviousness, can cause acute and chronic poisoning.Regulation one-level among the existing standard GB 15618-1995 (soil environment quality standard), secondary, three grades of soil environment quality standards are respectively in the per kilogram soil that lead tolerance is not more than 35,300,500mg, and lead content surpasses these international three rank standard values and is respectively in the present plastic sports ground of laying: 38 times, 4.5 times, 2.7 times, and the environment Lead contamination that it caused and the harm of health of people be can not be ignored.In addition, the harm of mercury is self-evident.
Summary of the invention
The objective of the invention is to overcome the above-mentioned shortcoming of original polyurethane plastic rubber paving material, the environment-friendly type sport field urethane surfacing material of a kind of TDI of not having and heavy metal contamination is provided.
Purpose of the present invention solves by the following technical solutions:
Sports place environment-protecting polyurethane plastic rubber paving material is made up of first component, second component, black micelle.The present invention produces first component, second component in advance, then at the construction field (site), first, second component according to 1: 2～6 mixed, is added 10～30% the black micelle that accounts for gross weight again, after mixing, mats formation, and spreads anti-skidding micelle, dry getting final product.
Above-mentioned first component, the composition and the content of second component are as follows:
(1) the first component is by 20～40 weight % diphenylmethanediisocyanates (being called for short MDI), and 10～30 weight %200 gasoline and 40～60 weight % polyether glycols are formed;
(2) the second component is made up of 20～50 weight % fillers, 1～10 weight %MOCA, 5～25 weight % polyether glycols, 30～60 weight % processing aids, 0.1～5 weight % pigment, 0.1～5 weight % antiaging agent, 0.1～5 weight % UV light absorber and 0.1～5 weight % mould inhibitor.
Wherein MDI is 2,4 ' diphenylmethanediisocyanate (MDI-50), 4,4 ' diphenylmethanediisocyanate (MDI-100), one or more in the liquefied mdi.
Polyether glycol is N-210, N-220, N-2028, N-403, N-3050, N-1618, one or more among the N-330;
Filler is a potter's clay, talcum powder, white carbon black, lime carbonate, one or more in the kaolin;
Processing aid is a clorafin, stearic acid, dibutyl phthalate, one or more in the dioctyl phthalate (DOP);
Pigment is red iron oxide, Phthalocyanine Green G, iron oxide yellow, one or more in the husky Huang of the Chinese;
UV light absorber is UV531 or UV-9;
Antiaging agent is one or both in 1010,7501.
Playground polyurethane plastic rubber paving material of the present invention does not contain heavy metal lead, does not contain TDI, reduces the pollution of environment, improves people's health level.Product meets State Standard of the People's Republic of China GB/T 14833-93 (plastic cement race track): hardness (Shao A) (degree): 45-60, tensile strength (MPa) 〉=0.7, elongation rate of tensile failure (%) 〉=90, compression recovery rate (%) 〉=95, rebound value (%) 〉=20, flame retardant resistance (level): 1.
