Abstract

The invention relates to the field of comprehensive utilization of industrial solid wastes, in particular to a wood-like structure material prepared from serpentine tailings and a preparation method of the wood-like structure material. The wood-like structure material is prepared from the following raw materials in parts by weight: 50-60 parts of serpentine tailings, 20-30 parts of PVC, 5-8 partsof an auxiliary agent and 7-12 parts of a modifier. According to the wood-like structure material, serpentine tailings are adopted as a raw material, so resource utilization of solid waste is achieved, and site resources occupied by landfill are reduced; the wood-like structure material has the advantages of water resistance, corrosion resistance, insect attack resistance, fire resistance, heat preservation and low expansion coefficient. According to the wood-like structure material, through optimization of the raw materials, the preparation method is simple, and compared with other types of structural materials, manpower and material resources are greatly saved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of industrial solid waste, in particular to a wood-like structure material prepared by using serpentine tailings and a preparation method thereof. Background technique [0002] Serpentine tailings are wastes produced during serpentine mining, accounting for about one-third to two-thirds of the total mining volume. Due to the large amount of serpentine mining, a large number of serpentine tailings are produced. At present, the resource utilization of serpentine tailings is mainly reflected in the purification of metals or oxides, but the utilization of serpentine tailings is relatively small. The accumulation and landfill methods are still the main treatment methods, which cause serious environmental pollution and harm, and at the same time, it is easy to form dust phenomenon, cause dust pollution, and cause harm to human health. How to reduce the pollution of serpentine tailings accumulat...
