According to the data comparison of embodiments 5-7 in table 1, the phenyl tri (2, 4-di-tert-butyl) phosphite is added, so that the synergistic cooperation of dimethyl glutarate, dicoumarol and benzoin dimethyl ether is promoted better, the bonding strength of the wall body and the heat-insulating plate is improved better, the wall body is not easy to separate from the heat-insulating plate when a heavy object is hung on the wall body, the compressive strength of the wall body is improved better, the wall body is not easy to crack when pressure or impact force is applied to the wall body, the service life of the wall body is prolonged better, and the later maintenance cost of the wall body is lower.
According to the comparison of the data of the embodiment 5 and the embodiments 8-13 in the table 1, the single addition of the hexabenzocoronene is beneficial to better improving the compressive strength of the wall body, so that the wall body is less prone to cracking when being subjected to pressure or impact force, the service life of the wall body is better prolonged, and the later maintenance cost of the wall body is better reduced; and through adding quinacridone alone, the compressive strength to the wall body does not play the influence almost, only when adding hexabenzocoronene and quinacridone mutually in coordination simultaneously, just can promote the effect of hexabenzocoronene better for the compressive strength of wall body is stronger, makes the wall body be difficult to the fracture when receiving pressure or impact force more, is favorable to prolonging the life of wall body better, makes the later maintenance cost of wall body lower.
According to the comparison of the data of the embodiment 5 and the comparative examples 1 to 4 in the table 1, the bonding strength of the concrete and the insulation board can be better improved only when dimethyl glutarate, dicumarol and benzoin dimethyl ether are cooperatively matched with each other, so that the wall body and the insulation board are not easy to separate, the compressive strength of the wall body is favorably improved, any substance is lacked, and the bonding strength of the wall body and the insulation board and the compressive strength of the wall body are easily influenced.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
