Problems solved by technology

However, the disadvantages of various artificial lightweight soils with different components are that containers are required for shape dispersion, and the relatively heavy weight leads to relatively simple design techniques and plant selection, and the containers placed on the load-bearing structure are easy to fall, posing safety hazards

Abstract

The present invention discloses a biological carbon polyurethane composite material for plant cultivation. The material is prepared by mixing the following components: 30-35 parts of polyether polyol, 0.30-0.40 part of a catalyst, 0. 8-1.0 part of a foam stabilizer, 45-75 parts of a plant culture matrix material and 15-25 parts of isocyanate. The composite material provides air and nutrient needed for plant growth, has the advantages of small proportion, high toughness and good fertilizer and water conservation effect, and is applicable to plant root growth; and the biological carbon as environmental protection functions of adsorbing PM2.5 in the air and purifying haze.

Description

technical field [0001] The invention relates to a polyurethane material, in particular to a biochar polyurethane composite material used for plant cultivation. Background technique [0002] There are many high-rise buildings in modern cities, and there are fewer and fewer planar spaces available for greening. The greening of three-dimensional spaces such as building roofs, garage ceilings, walls, balconies, and window sills has become an important means of improving the urban ecological environment. The development of three-dimensional greening can enrich the spatial structure level of urban landscaping and the artistic effect of urban three-dimensional landscape, help to further increase the amount of urban green, reduce the heat island effect, absorb dust, reduce noise and harmful gases, and create and improve the urban ecological environment. However, the traditional greening load is heavy, and the newly developed light-substrate nutrient soil is bulky and loose, with poo...
