Problems solved by technology

In order to improve the problem of roof greening and drought resistance, patent No. ZL200920087198.6 of "Filter water retention blanket for roof greening" has appeared in recent years. Although it solves the problem of roof greening water and soil conservation, it still does not solve the problem of roof runoff water pollution
Because particulate matter in the air in urban environments often contains heavy metals, organic pollutants will also fall onto the roof with rainwater, together with fertilizers, organic matter and particulate components in the planting substrate, will release pollutants during rainfall, causing roof runoff Heavy metals, nitrogen and phosphorus, and organic pollutants exceed the standard

Abstract

The invention relates to a water retention and purification blanket used for a green roof and a manufacturing method thereof and belongs to the field of building materials. Upper-layer non-woven fabric and middle-layer fabric are sewn through stitch-bonded threads, material fibers having even thickness are loaded between the two layers of fabric, and the surfaces of the fibers are covered with an attapulgite clay layer. The middle-layer non-woven fabric and lower-layer non-woven fabric are connected through a needle punching technology, and a mixture of active carbon granules and red algae powder which are evenly mixed is loaded between the two layers of non-woven fabric. The filtering and water retention blanket is used between a water drainage layer and a planting layer to replace a traditional filtering layer, in this way, soil loss can be prevented, roof runoff can be purified, and a certain water retention function is achieved. The blanket is reasonable in structure, raw materials are sufficient, processing is convenient, the price is low, and the blanket is durable and good in filtering effect.

Description

technical field [0001] The invention relates to a material for roof greening, in particular to a water-retaining and water-purifying blanket for a green roof and a manufacturing method thereof, belonging to the field of building materials. Background technique [0002] The structure of a green roof is generally a structural layer, a waterproof layer, a drainage layer, a filter layer, a planting layer and vegetation on it. In the prior art, the artificially prepared base material is generally used for the planting layer, which is generally a mixture of coarse-grained materials such as ceramsite, river sand, organic matter, fertilizer, and topsoil. The filter layer is made of textile products, and its function is to filter and block the fine particles in the planting layer to prevent soil loss. In order to improve the problem of roof greening and drought resistance, patent No. ZL200920087198.6 of "filter water retention blanket for roof greening" has appeared in recent years....
