Problems solved by technology

[0003] The current plastic track mainly has the following problems: (1) Since the raw materials contain an excessive amount of volatile TDI, and it usually takes about 2-3 days to cure after construction, there will be more free TDI during or after construction. Volatile release of TDI into the environment
(3) At present, solvents such as toluene and xylene are used to varying degrees in the construction process of plastic runways, which will also cause pollution to the environment
[0004] Sports are for health, but the current non-environmental protection of plastic track materials has hidden dangers of harming people's health, which has caused great anxiety in all walks of life

Description

technical field [0001] The invention relates to a material for laying a plastic track, specifically a polyurethane track glue; the invention also relates to a production method of the polyurethane track glue and a construction method of a plastic track using the track glue. Background technique [0002] The known plastic runway, that is, the main component of the polyurethane runway is polyurethane glue, which adopts first and second components. Component A is a prepolymer polymerized by excess isocyanate and polyether polyol, and Component B is composed of chain extender (or crosslinking agent or curing agent), filler, and auxiliary agent. Some types of agents also require a catalyst. In order to improve the physical and mechanical properties of the runway, the additives used are mostly one or more of plasticizers, stabilizers, aging agents, light stabilizers, modifiers, wetting agents, etc. During construction, the components A and B are mixed on site, and the prepolymer...
