Problems solved by technology

[0003] These organic solvents will eventually volatilize into the atmosphere, and polyurethane runways will produce some irritating odors during high temperature use. Therefore, traditional polyurethane runways will have real and potential impacts on construction personnel and the atmospheric environment in terms of production materials and construction links. In addition, during construction, if the polyurethane material with a good ratio cannot be used within four hours, it will be solidified and scrapped, resulting in loss and waste of materials

Abstract

The invention discloses a new nano material rubber runway and a manufacturing method thereof. The new nano material rubber runway is mainly prepared from the following raw materials in parts by weight: 40-80 parts of rubber particles, 50-80 parts of a gelatinizing agent, 10-60 parts of a polyether mixture, 10-30 parts of an aluminum hydroxide flame retardant, 5-10 parts of sulfur, 5-10 parts of hydroxyl-terminated polybutadiene, 10-15 parts of sodium molybdate, 1-5 parts of glass fiber powder and 100-200 parts of filler. The gelling agent is a mixture of a phenolic resin adhesive and an epoxy resin adhesive. The preparation method of the polyether mixture comprises the following steps: mixing talcum powder and polyether polyol according to a weight ratio of 1: (0.5-0.8), adding the new nano material modified polyurethane binder, and uniformly mixing to obtain the polyether mixture. According to the rubber runway disclosed by the invention, through synergistic cooperation of the raw materials, the obtained rubber runway has excellent physical and mechanical properties and excellent tensile strength and wear resistance; in addition, the product is free of carbon dioxide residue and free of secondary pollution to the environment; and the cost is reduced by recycling the gelling agent, and the rubber runway is safe and environment-friendly.

Description

Technical field [0001] The present invention belongs to the technical field of rubber track, more particularly to a new nano-material rubber track. Background technique [0002] Currently widely oily pavement plastic track is two-component polyurethane (PU) polyurethane adhesive PU runway. Polyurethanes PU runway production materials commonly used tolylene diisocyanate (TDI) or diphenylmethane diisocyanate (MDI), in the construction process to add an organic solvent (such as xylene or ethyl acetate, etc.) as a diluent, sometimes to add driers to promote drying. [0003] These organic solvents will eventually evaporate into the atmosphere, and the polyurethane runway during use at high temperatures will produce a number of irritating odor, and therefore, the conventional polyurethane production runway construction materials and aspects of the real part of the construction and generating atmosphere and are potentially hazards; in addition, in the construction, if proportioned polyu...
