Abstract

The invention relates to the technical field of landscape materials, and provides a preparation method of an indoor landscape model building material in order to solve the problem that the existing building model material is non-renewable, which comprises the following steps: by using torreya grandis waste residue as a raw material, mixing with an inorganic high-activity material bentonite to forman organic-inorganic hybrid adsorption material; and further preparing the multifunctional landscape model building material. The prepared building material is low in cost, excellent in adsorption effect, light in weight and diverse in function, has ornamental value and meanwhile meets the environmental protection requirement.

Description

technical field [0001] The invention relates to the technical field of landscape materials, in particular to a method for preparing indoor landscape model building materials. Background technique [0002] Chinese torreya is a yew family plant, a native tree species in China, and a typical biomass plant. Torreya not only has important ornamental value, but also the deep-processed Torreya series products can be used in many fields such as health care, medicine, food and environmental protection. Yet there is a very thick fleshy exocarp of one deck outside the torreya seed, accounts for about 50%~60% of fresh weight of seed. The thousands of tons of green fruit peels produced in the deep processing of Torreya per year are all discarded, resulting in a waste of Torreya resources. The resource utilization of Torreya waste is a major problem in the Torreya producing area. At present, it is mainly disposed of by landfill or incineration. Therefore, it is of great significance to ...
