Degradable wind-shielding and sand-fixing sponge ring and preparation method thereof

Abstract

The invention discloses a degradable wind-blocking sand-fixing sponge ring and a preparation method thereof. The degradable wind-blocking sand-fixing sponge ring is prepared from the following components in parts by weight: 20-35 parts of desert sand, 45-55 parts of Wuhai red clay, 7-11 parts of front flag feldspar, 5-10 parts of Wuchuan feldspar, 10-15 parts of carbonaceous coal gangue, 5-10 parts of calcium silicate fly ash, 3-10 parts of pore-forming agent and 0.2-0.4 part of organic binder CMC. The desert sand comprises the following chemical components in percentage by weight: 74.15% of SiO2, 9.66% of Al2O3, 3.07% of Fe2O3, 0.47% of TiO2, 3.38% of CaO, 1.26% of MgO, 2.36% of K2O, 1.94% of Na2O and 3.43% of ignition loss. Main raw materials are taken from local natural waste or industrial solid waste in desert areas, waste is turned into wealth, and the prepared sponge ring not only can block wind and stabilize sand, but also can be weathered and degraded into powder along with thenature along with the growth of plants, returns to the nature and does not generate secondary solid waste pollution.

Description

technical field [0001] The invention relates to the technical field of desert plant planting protection products, in particular to a degradable wind-shielding sand-fixing sponge ring and a preparation method thereof. Background technique [0002] my country is one of the countries most affected by land desertification in the world. The national desert, Gobi and desertification land are about 1.653 million square meters. Desertification has brought great harm to the ecological environment and social economy. First, it destroys the ecological balance. The deterioration of the environment and the serious decline of land productivity endanger the survival and development of the people in the desertification area. Second, it leads to the loss of large areas of available land resources, reduces the living space of the people, and seriously restricts the sustainable development of the social economy. [0003] In order to prevent the continued expansion of land desertification, impro...

Problems solved by technology

[0004] In order to solve the technical problem that existing sand-fixing rings have poor wind-proof sand-fixing, water-retaining and moisturizing effects, and are not easy to degrade, the present invention provides a degradable wind-blocking sand-fixing sponge ring and its preparation method, making full use of local natural waste and Industrial solid waste raw materials, turning waste into treasure, the prepared sponge ring can not only block the wind and fix sand, but also degrade with the natural weathering and become powder as the plants become useful, return to nature, and do not produce secondary solid waste pollution
