Abstract

The invention relates to a water-based prefabricated rubber runway and a preparation process thereof, and belongs to the field of synthetic material preparation. The water-based prefabricated rubber runway is provided against the problem that in the prior art, a water-based polymer cannot be used as a raw material for obtaining the low-toxicity rubber runway. The water-based prefabricated rubber runway comprises a wear-resistant layer and an elastic layer, and the wear-resistant layer is prepared from, by weight, 5-10 parts of water-based acrylic acid, 5-10 parts of waterborne polyurethane, 75-88 parts of solid raw materials, 2-5 parts of an inorganic color filler and 0.2-3 parts of an accelerant; and the elastic layer is prepared from, by weight, 5-10 parts of the waterborne polyurethane,5-10 parts of the water-based acrylic acid, 80-90 parts of the solid raw materials and 0.2-3 parts of the accelerant, wherein the solid raw materials comprise rubber powder and rubber particles. Thepreparation process comprises the following steps: 1, material mixing; 2, drying; 3, initial pressing; and 4, secondary pressurization. The problem in the prior art is solved in the invention.

Description

technical field [0001] The invention belongs to the field of synthetic material preparation, in particular to a water-based prefabricated rubber runway and a preparation process thereof. Background technique [0002] In order to save manufacturing costs and reduce processing difficulty, the runway is usually prepared by pouring on site, that is, oily polyurethane as a binder is mixed with rubber particles and then paved on site. Because the PU glue used is multi-component, containing harmful ingredients such as TDI and MDI, and the on-site construction operation, its dosage and ratio cannot be strictly controlled, and incomplete reactions often occur under multi-components, resulting in complex material components, which leads to " The main reason for the frequent occurrence of poisoned runway incidents. [0003] Under the environmental protection background of "oil to water", water-based polymers are continuously introduced in the chemical and synthetic material industries...
