Embodiment 1

[0021] Example as figure 1 Shown: Both sides of the middle metal foil layer 1 are composited with maleic anhydride grafted modified polyethylene resin layer, the lower layer maleic anhydride grafted modified polyethylene resin layer 2 is bonded with non-woven fabric 3, and the upper layer maleic anhydride grafted modified polyethylene resin layer is bonded to it. A nonwoven fabric layer 5 is stuck on the branch modified polyethylene resin layer 4 .

Embodiment 2

[0022] Embodiment two is a simple product such as figure 2 Shown: one side of the metal foil layer is compounded with a maleic anhydride grafted modified polyethylene resin layer, and a nonwoven fabric layer is adhered to the maleic anhydride grafted modified polyethylene resin layer.

[0023] The first production method of the anti-plant root puncture polymer composite waterproof coiled material of the present invention: adopts the dual-die cast composite process flow and the extrusion cast plastic composite machine, and adds maleic anhydride grafted modified polyethylene resin into two Taiwan extruder die head 6,7, heat extrusion maleic anhydride graft modified polyethylene resin casting film layer 2 ', 4 ', metal foil layer 1 is placed between two extruder die heads, put Two rolls of non-woven fabrics 3 and 5 are placed outside the die heads of the two extruders. The above five layers of materials are unrolled and flattened, and then pressed into one body by the heat-seali...

Abstract

The polymer coil resisting prick of plant root consists of metal foil layer, maleic anhydride grafted and modified polyethylene resin layer and adhered non-woven fabric or felt layer. The metal foil layer is aluminum or copper foil layer; the non-woven fabric layer is hot rolled polypropylene or terylene filament fabric or needle punched polypropylene or terylene staple fiber. The polymer coil may be produced through double die head flow casting compounding process or far infrared heated secondary compounding process and through unwinding, rolling, cooling, length counting, edge cutting, winding, packing and other steps. The polymer coil may be used widely in roof garden, roofing, and other places.

Description

technical field [0001] The invention relates to a waterproof material for construction engineering, in particular to a waterproof coiled material resistant to plant root puncture. Background technique [0002] Planting flowers, trees and other plants on the roof of the building and the top of the underground project to build a green sky garden can create a good local microclimate and make up for the loss of green space caused by the development of construction projects. It has the characteristics of improving the thermal insulation effect of buildings, reducing energy consumption, improving the waterproof ability and service life of buildings, increasing the use functions of buildings, rationally utilizing space resources, and increasing economic benefits. At present, with the improvement of people's awareness, as far as the roof is concerned, it has evolved from a light garden roof of a single grass plant to a heavy garden roof that can have pavilions, shrubs, trees, pools,...
