Description
技术领域 technical field
本发明涉及的是一种用于绿化的保水材料，用于屋顶墙面绿化或墙面绿化植物生长。 The invention relates to a water-retaining material for greening, which is used for roof wall greening or wall greening plant growth.
背景技术 Background technique
现有屋顶墙面绿化主要使用轻量土，而减少重量是有限的。为了普及屋顶墙面绿化，因为屋顶的负荷是有限的，所以有必要进一步减少重量；使用土壤的薄层低矮植物的栽培方法，屋顶墙面绿化的轻量化也成为可能；但是，薄层低矮植物因为土壤的使用量少而出现保水能力差的问题；因此，开发轻量的基质保水材料，能有效地保持雨水是非常重要的事。 The existing roof and wall greening mainly uses lightweight soil, and the weight reduction is limited. In order to popularize roof and wall greening, because the load on the roof is limited, it is necessary to further reduce the weight; the cultivation method of low-growing plants using a thin layer of soil also makes it possible to reduce the weight of the roof and wall greening; however, the thin layer is low Dwarf plants have a problem of poor water retention due to the small amount of soil used; therefore, it is very important to develop lightweight substrate water-retaining materials that can effectively retain rainwater.
现有的基质保水材料，使用的是织布和聚氨酯泡沫类似物等。另外，在薄层植物的下面设置发泡聚苯乙烯的托盘，以此来储存并提供水。但是，这些材料成本高，需要更廉价的保水材料。此外，这些材料来源于石油，而屋顶墙面绿化的保水材料是以改善城市环境作为目标，因此使用非石油来源的材料是非常重要的。另外，在墙面绿化的情况下，藤性植物的根部进入墙面防止植物的脱落是十分重要的，不过，在现有的墙面绿化材料中没有考虑到此性能。 Existing matrix water-retaining materials use woven fabrics, polyurethane foam analogs, and the like. In addition, expanded polystyrene trays are placed under the thin layer of plants to store and provide water. However, these materials are costly, requiring cheaper water-retaining materials. In addition, these materials are derived from petroleum, and the water-retaining materials for green roofs and walls are aimed at improving the urban environment, so it is very important to use non-petroleum-derived materials. In addition, in the case of wall greening, it is very important for the roots of rattan plants to enter the wall to prevent the plants from falling off, but this performance has not been considered in the existing wall greening materials.

The surface of this base underlayment is spray coated with a surfactant solution (10% in water), which impregnates the underlying structure. After drying at 150° C. for about 1 hour, a wood fiber board with water-retaining material can be produced.
通过安装制造为保水材料的薄层基础植物木质纤维板，以制造出轻量级的绿化构造体。在薄层的低矮植物生长的同时，根会进入木质纤维板，它可以用作轻量稳定的绿化结构。 Lightweight greenery structures are created by installing thin-layer base plant wood fiber boards manufactured as water-retaining materials.
