Abstract
The invention discloses a polyurethane runway rubber, which comprises a modified polyether, fillings and diphenylmethane diisocyanate which improve the adhesiveness of the runway rubber with weight proportion of 45-53:45-53:5-7. The invention uses wastes produced in chemical production to process the modified polyether into the rubber. The rubber produced has the advantages of fine bond strength, fine fluidity and fine smoothness when in paving, thus guaranteeing construction quality, simplifying production art, shortening production cycles, largely reducing cost, improving competitiveness, having no poisonous free TDI and MOKA, and being environmental products.
Description
Technical field
The present invention relates to a kind of polyurethane runway rubber.
Background technology
Universal polyurethane runway rubber mixes stirring by two kinds of components and obtains, and wherein the first component is that polypropylene glycol-tolylene diisocyanate (TDI) gives aggressiveness, and isocyano (NCO%); The second component is that polyether Glycols, polyether-tribasic alcohol, vulcanizing agent methylene-bis-o-chloroaniline (MOKA needs 110 ℃ of fusings), catalyzer, filler, pigment stir and forms through grinding.Be with first component and the second component mixing and stirring plastic cement race track that can pave according to a certain percentage during on-the-spot the use.The process cost height of this traditional mode of production runway rubber, environment there is pollution; Raw material variety is many, complex manufacturing, and the production cycle is long, and operational procedure is loaded down with trivial details, and efficient is not high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of polyurethane runway rubber, and this runway rubber composition is simple, and production technique is simplified, and has shortened the production cycle, and construction cost reduces greatly.
For solving the problems of the technologies described above, technical scheme provided by the present invention is: a kind of polyurethane runway rubber, this runway rubber includes modified polyether, increases the filler and the diphenylmethanediisocyanate of runway rubber viscosity, and weight proportion is 45～53: 45～53: 5～7.
This runway rubber also includes pigment, and the part by weight of interpolation is 1.5% of a modified polyether.
The polyether glycol of described modified polyether for from the waste material that contains the urethane composition, extracting.
The weight proportion of described modified polyether, filler and diphenylmethanediisocyanate is 50: 50: 6.
The advantage that the present invention has: the modified polyether that the waste that produces in the employing Chemical Manufacture processes, the first, cost is low, this polyethers is a four-functional group in addition, the molecular weight height, and made glue bond intensity is good, good fluidity, planeness is good when paving, and has guaranteed construction quality; The second, simplified production technique, shortened the production cycle, cost significantly reduces, and has improved competitive power; The 3rd, single stage method improves operating efficiency greatly; The 4th, do not contain deleterious free TDI and MOKA, be environmentally friendly machine.
Embodiment:
Embodiment 1
A kind of polyurethane runway rubber, this runway rubber include modified polyether, increase the filler and the diphenylmethanediisocyanate of runway rubber viscosity, and weight proportion is 50: 50: 6.This runway rubber also includes pigment, and the part by weight of interpolation is 1.5% of a modified polyether.Can allocate various pigment according to different requirements.
Wherein, the polyether glycol of modified polyether for from the waste material that contains the urethane composition, extracting.Filler adopts to be meant being viscosity and other performance that increases product, and the powder of Zeng Jiaing in process of production is such as the material of dry powder and so on.
Embodiment 2
A kind of polyurethane runway rubber, this runway rubber include modified polyether, increase the filler and the diphenylmethanediisocyanate of runway rubber viscosity, and weight proportion is 45: 45: 5.This runway rubber also includes pigment, and the part by weight of interpolation is 1.5% of a modified polyether.Can allocate various pigment according to different requirements.
Wherein, the polyether glycol of modified polyether for from the waste material that contains the urethane composition, extracting.Filler adopts to be meant being viscosity and other performance that increases product, and the powder of Zeng Jiaing in process of production is such as the material of dry powder and so on.
Embodiment 3
A kind of polyurethane runway rubber, this runway rubber include modified polyether, increase the filler and the diphenylmethanediisocyanate of runway rubber viscosity, and weight proportion is 53: 53: 7.This runway rubber also includes pigment, and the part by weight of interpolation is 1.5% of a modified polyether.Can allocate various pigment according to different requirements.
Wherein, the polyether glycol of modified polyether for from the waste material that contains the urethane composition, extracting.Filler adopts to be meant being viscosity and other performance that increases product, and the powder of Zeng Jiaing in process of production is such as the material of dry powder and so on.
The constructional method of polyurethane runway rubber of the present invention is " single stage method ", promptly no longer is first and second material mixing and stirring plastic cement race tracks that can pave according to a certain percentage during site operation, but adds siccative according to a certain percentage in host, directly paves into glue then.
Polyurethane runway rubber of the present invention is made up of siccative and host, and siccative is not the aggressiveness that gives that tradition contains free TDI, and what use is nontoxic simple diphenylmethanediisocyanate (MDI), need not synthesize.Host is made up of modified polyether, filler, pigment, and mixing and stirring does not add vulcanizing agent MOKA through grinding, and does not add catalyzer, need not heat, and has simplified production technique, has shortened the production cycle.Modified polyether is to be processed by the scrap stock that produce in the Chemical Manufacture, so cost reduces greatly.
The modified polyether that the present invention adopts the Chemical Manufacture waste to process is turned waste into wealth, and cost significantly reduces, and has simplified production technique, has shortened the production cycle.Use MDI, site operation is become single stage method by traditional two-step approach.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
