The bottom surface of the middle plastic plate of this scheme is opened there is a plurality of storage heavy tanks, is equipped with fine sand in the storage heavy tank, and when waterproof board burning or high temperature melting deformation back, fine sand in the storage heavy tank flows out, covers on bottom plastic plate and pitch waterproof layer to play fire-retardant effect.
Preferably, the grain size of the fine sand is 10-50 meshes. In the scheme, the fine sand particles are 10-50 meshes, so that the fine sand particles have fluidity, and have good flame retardant effect.
As optimization, a flame-retardant cloth is arranged between the middle plastic plate and the top plastic plate, and two sides of the flame-retardant cloth are respectively connected with the middle plastic plate and the top plastic plate in an adhesive mode. The fire-retardant cloth that sets up in this scheme can effectively keep apart middle plastic slab and top plastic slab, plays fire-retardant isolated effect.
As optimization, a geonet is arranged between the middle plastic plate and the asphalt waterproof layer, and two sides of the geonet are respectively connected with the middle plastic plate and the asphalt waterproof layer in an adhesive manner. The geonet in this scheme plays the effect of strengthening, improves the tensile properties of waterproof board, connects the bottom surface of middle plastic slab as an organic wholely simultaneously, prevents to store sink tank bottom fracture.
As optimization, the storage sink tanks are rectangular tanks, a plurality of storage sink tanks are arranged in a rectangular array, and the distance between adjacent storage sink tanks is 1-4mm. In the scheme, the storage sink grooves are rectangular grooves, and the distance between adjacent storage sink grooves is 1-4mm, so that the storage capacity of fine sand is increased.
And optimally, the depth of the storage sink is 2-6mm. The degree of depth of storage heavy groove is 2-6mm in this scheme, and the degree of depth is too little then can lead to the storage volume of fine sand too little, and the degree of depth is too big then can lead to waterproof board thickness too big.
As optimization, the thickness of the bottom plastic plate and the asphalt waterproof layer is smaller than 1.2mm. In this scheme, the thickness of bottom plastic slab and pitch waterproof layer is all less than 1.2mm to the flame retardant efficiency is realized easily to accessible fine sand.
The beneficial effects of the utility model are as follows: according to the flame-retardant plastic waterproof board, the fine sand is filled in the storage sink, and after the waterproof board burns or is melted and deformed at high temperature, the fine sand in the storage sink flows out and is covered on the bottom plastic board and the asphalt waterproof layer, so that the flame-retardant plastic waterproof board has a flame-retardant effect, physical flame retardance is realized, materials are not required to be improved, the materials are all existing products, the cost is reduced, and the production convenience is improved.
