Abstract

The invention discloses a soil improver utilizing waste rubber powder as a main raw material and a preparation method of the soil improver. The soil improver comprises the following raw materials in parts by weight: 55 to 70 parts of waste rubber powder, 30 to 40 parts of desulfurized waste, 2 to 8 parts of inorganic accelerant and 4 to 8 parts of organic accelerant. The soil improver also comprises 0 to 3 parts of other ingredients which are selected from organic fertilizer, biomass char and microorganism fertilizer. According to the soil improver, by utilizing the stabilizing effect of the waste rubber powder, the ion exchanging efficiency of the improver and a snow-melting agent in the soil is promoted. Sodium ions of the snow-melting agent in the soil are replaced by utilizing calcium ions in desulfurized waste, particularly in coal-fired flue gas desulfurized gypsum, so that the acidity and alkalinity of the soil can be improved. The aggregate structure of the soil is improved by utilizing the inorganic accelerant, particularly the decomposed coal. In addition, the nutritional ingredients of the soil can be further improved by utilizing the auxiliary fertilizer.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a soil conditioner using waste rubber powder as a main raw material and a preparation method thereof. Background technique [0002] Snowfall in winter seriously affects the safety of road travel, especially for large and medium-sized cities and main highways. Snow and ice on roads in winter will not only affect social production and people's lives, but also increase the incidence of traffic accidents, which will seriously affect the lives of travelers. Security is a threat. At present, there are three ways of snow removal, namely manual snow removal, mechanical snow removal and snow-melting agent snow removal; among them, snow-melting agent snow removal has been proved to be a relatively fast and simple snow removal method, which is widely used in cities and expressways. The deicing agent is divided into three categories according to the different ingredient...
