Problems solved by technology

[0004] In view of the large one-time investment and high maintenance cost of the greening construction project on the roof / top surface, it is not easy to repair if leakage occurs. Therefore, when designing the greening project on the roof / top surface, it is necessary to do a good job of the waterproof system to avoid The phenomenon of roof / top surface leakage occurs 2-3 years after the construction is completed, and the ordinary waterproof system is built in the greening project of the roof / top surface, which does not guarantee the quality of the planted roof / top surface system. This is because the plants The root system will have a huge destructive force on ordinary waterproofing

Embodiment Construction

[0028] see figure 1 , an embodiment of a thorn-resistant waterproof roll material given in the present invention, comprising a modified asphalt waterproof layer 1, a metal foil layer 2 and a polyester tire 3, wherein the polyester tire is made by special Modified asphalt prepreg treatment. In this embodiment, it includes PE film layer 4, modified bitumen waterproof layer 1, metal foil layer 2, polyester tire 3 pre-impregnated with special modified bitumen, modified bitumen waterproof layer 1 and PE Film layer 4. Of course, other forms of layered structure can also be used, but it mainly has three basic components: modified asphalt waterproof layer 1, metal foil layer 2 and polyester tire 3. So that the coil has the effects of root resistance and waterproof function. The polyester tire 3 in the present invention is pre-soaked with special modified asphalt, so that it has dual functions of waterproofing and preventing plant roots from penetrating, can withstand the puncture o...

Abstract

The invention provides a root thorn-proof and waterproof coiled material, which comprises a modified asphalt waterproof layer, a metal foil layer and a polyester tire, which are composited together. The polyester tire is presoaked by special modified asphalt. The root thorn-proof and waterproof coiled material is formed by the composite of the modified asphalt waterproof layer, the metal foil layer and the polyester tire, wherein the polyester tire is presoaked by the special modified asphalt, so that the root thorn-proof and waterproof coiled material has double functions of the water resistance and the penetration resistance of plant roots, can prevent from being penetrated by plant root hairs, and keeps the waterproof function for a long time.

Description

technical field [0001] The invention relates to a plant root thorn resistant waterproof coiled material, in particular to a plant root thorn resistant waterproof coiled material using modified asphalt and a processing technology. Background technique [0002] With the expansion of the scale of modern cities, the area of ​​urban buildings and roads continues to increase, which leads to the reduction of green area, the reduction of urban dust adsorption capacity, the increase of particle dust content, and the air dry city temperature is higher than the surrounding temperature. Therefore, it is of great significance to carry out urban greening to alleviate these phenomena in the city and greatly improve the urban aerial landscape. Studies have shown that under normal circumstances, 30% to 50% of the green coverage is critical to the ecological balance of a city, that is, if it reaches or exceeds this range, the ecological environment is expected to develop into a virtuous circl...
