Abstract

A garden waste-based organic-inorganic composite fire-free lightweight glazed material, the raw materials of which include: garden waste, inorganic fine aggregate, mineral admixture, lightly burned magnesium oxide, magnesium sulfate, defoamer, water reducer , composite modifier, coupling agent, water-based color paste, glaze treatment materials and water. Its density is 0.83‑1.25g / cm 3 , the flexural strength can reach more than 10MPa, and the compressive strength is 21.77‑34.17MPa. It has the characteristics of light weight, high strength and beautiful appearance. The high doping content of solid waste can quickly realize the recycling of garden waste. Its preparation method is simple, does not require high-temperature sintering, is easy to produce and deploy, does not require special large-scale equipment, greatly reduces production costs and difficulty in recycling, and at the same time, the material has stable properties and has the characteristics of light weight and high strength.

Description

technical field [0001] The invention relates to the field of solid waste utilization and preparation of new composite materials, in particular to a garden waste-based organic-inorganic composite non-fired lightweight glazed material and a preparation method. Background technique [0002] Landscaping plays an important role in improving urban environmental quality, alleviating urban heat island effect, and maintaining urban ecological balance. With the continuous advancement of ecological construction and urban greening, the amount of garden waste is increasing, and it has become the third largest urban solid waste after domestic waste and construction waste. [0003] Garden waste refers to wastes such as tree and shrub prunings, lawn prunings, weeds, fallen leaves, branches, discarded grass and flowers in gardens and flower beds produced during the natural or maintenance process of green plants in urban green land or suburban woodland. Traditionally, landfill and incinerati...
