Embodiment

[0017] A new light-weight wall material of plant straw, which is made of the following raw materials in parts by weight: 50 parts of fly ash, 30 parts of modified plant straw powder, 30 parts of sulphoaluminate cement, 20 parts of expanded perlite, and silica sand powder 15 parts, modified clay 15 parts, glass fiber 20 parts, foaming agent 4 parts, water reducing agent 5 parts.

[0018] The modified plant stalk powder is prepared by the following method: cutting the plant stalks into 3 cm particle segments, crushing them into powder, soaking them in 15% sodium hydroxide solution for 4 hours, removing them, and drying them at a temperature of 45°C Dry to 3% water content, then immediately add 4% chlorinated paraffin and mix evenly, then add 30% river sand, 5% carboxymethyl cellulose, mix evenly, granulate and dry.

[0019] The modified pottery clay is prepared by the following method: add 40% diatomaceous earth and 3% silane coupling agent KH550 to the pottery clay,...

Abstract

The invention discloses a plant straw novel lightweight wall body material. The plant straw novel lightweight wall body material is prepared by the following raw materials in parts by weight: 40-50 parts of fly ash, 20-30 parts of modified plant straw powder, 20-30 parts of sulphate aluminium cement, 10-20 parts of expanded perlite, 10-15 parts of silica powder, 10-15 parts of modified clay, 10-20 parts of glass fiber, 2-4 parts of foaming agent and 3-6 parts of water reducing agent. The plant straw novel lightweight wall body material disclosed by the invention is manufactured by utilizing an industrial waste material, namely the fly ash which is produced by abundant local coal mine resources and an agricultural waste, namely plant straw, so that the phenomena of disordered arrangement and disordered placement of the fly ash, excessive burning of the plant straw and the like can be effectively prevented, a natural environment can be protected, the production cost can be simultaneously greatly reduced, the cyclic utilization of the solid waste is realized and the energy-saving requirements of buildings can be also met. The produced wall body material has the advantages of higher compressive strength, smaller contractibility, light weight, heat preservation, heat insulation, sound insulation, fire resistance and the like.

Description

technical field [0001] The invention relates to a novel lightweight wall material of plant straw and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] At present, the wall materials commonly used in construction projects are concrete hollow blocks, aerated concrete blocks, and foam concrete blocks. Increase, the tendency of cracks in the wall will increase in turn, and there will be a greater engineering safety hazard. On the other hand, while China's economy is developing rapidly, the random discharge and placement of fly ash and the indiscriminate burning of plant straw have caused huge pollution to the environment. Therefore, it is of great significance to carry out comprehensive utilization of fly ash and plant straw. Significant economic and social benefits. Contents of the invention [0003] The object of the present invention is to provide a new light-weight wall material of plant stalks with high p...
