Abstract
The invention provides a nontoxic environment-friendly plastic ground for a kindergarten and a construction method. The nontoxic environment-friendly plastic ground comprises a base layer. A waterproof bonding layer is arranged on the base layer and partially permeates into the base layer. The waterproof bonding layer is sequentially provided with a bottom layer, a second bonding layer and a surface layer from bottom to top. The nontoxic environment-friendly plastic ground for the kindergarten has the advantages that only MID glue is used for bonding, and thus the bonding effect is good; due to the fact that the viscidity of the glue before solidification is small, construction is easier and more convenient compared with TDI, and smearing is easier and more uniform; the compatibility of the MDI glue contained in different layers can be guaranteed, and thus delamination is unlikely to occur; compared with a TDI glue system, the harm of the MDI glue to the human body is extremely small, so that pollution is avoided in the use process, and the softness and safety are good; the surface layer has ultraviolet ray blocking and toxic gas sealing functions to a certain extent, and thus the color of EPDM is unlikely to change in the use process, and pollution is smaller; and since the MDI glue content of each layer is high, compared with an ordinary plastic ground with the same thickness, the nontoxic environment-friendly plastic ground is good in elasticity and long in service life.
