Waterproof roll with plant root impaling resistance and manufacturing method thereof

Abstract

The invention relates to a waterproof roll with plant root impaling resistance and a manufacturing method thereof. The waterproof roll comprises a tyre basic layer, wherein the upper and lower surfaces of the tyre basic layer are provided with modified asphalt chemical root resisting agent waterproof layers; the outer surface of each modified asphalt chemical root resisting agent waterproof layer, which is far away from the tyre basic layer, is provided with an isolating layer; and the modified asphalt chemical root resisting agent waterproof layer is a structure manufactured by carrying out mechanical rabbling and blending on asphalt, a chemical root resisting agent, resin, a filler and an auxiliary agent at the temperature of 195 DEG C. The invention has the following advantages: the mildew-proof performance of the waterproof roll is enhanced, i.e. the waterproof roll does not generate toxin action on plants and effectively prevents the plant root from being impaled at the commissure of the roll; and the manufacturing method of waterproof roll of the invention is favor for realizing the automatized production line operation, and can greatly reduce the production cost under the condition of equal plant root impaling resistance, thereby being suitable for large-scale application.

Description

technical field [0001] The invention belongs to the field of manufacturing waterproof materials for construction engineering, and in particular relates to a plant root puncture-resistant waterproof coiled material and a manufacturing method thereof. Background technique [0002] Nowadays, there are more and more places involving roof greening in construction projects. The so-called roof greening refers to covering the roof of a building with green plants, and matching the nutrient soil layer, water storage layer and roofing required for plant survival. Plant root blocking layer, drainage layer, waterproof layer. Roof greening can not only create a beautiful local environment with pavilions, shrubs, etc. for the overall architectural design, but also increase the use function of the building, thereby satisfying and improving people's visual enjoyment and life taste. However, any roof greening project will face the problem of waterproof leakage, because many plants have a wel...

AI Technical Summary

Problems solved by technology

However, any roof greening project will face the problem of waterproof leakage, because many plants have a well-developed root system, they can penetrate the waterproof layer, even the structural layer, if there is no reliable quality waterproofing against plant root puncture during construction materials, it is easy to cause serious leakage on the green roof

[0003] The waterproof coiled materials used in the prior art to prevent plant root puncture mostly use the principle of physical root resistance. Although these waterproof coiled materials can play a certain role in preventing plant root puncture, their disadvantages are that they are not adaptable and cannot meet the requirements of different industries. The performance indicators of materials such as waterproof and strength specified by the roof, and the production process of some waterproof membranes are also relatively complicated, which increases the production cost

For example: the waterproof membrane with the fabric layer can not adapt well to the high temperature and humid acidic soil environment in the south, and the material is easy to age; in addition, the test of the waterproof membrane with the metal foil layer structure shows that simple metal ions are harmful to plants. Shows indeterminate toxins and is only effective against plant root punctures when the plant roots are in direct contact with the metal. In addition, the metal acts as a mechanical barrier, it does not protect the seam of the membrane, and the plant root can still penetrate through the seam Pass
