Light aggregate for composite thermal-insulation and fire-prevention wall material, and production method thereof

Abstract

The invention provides a light aggregate for a composite thermal-insulation and fire-prevention wall material, and a production method thereof, and relates to a light aggregate for preparing wall materials, and a production method thereof. A purpose of the present invention is to solve problems of large weight of the wall material prepared by adopting sand and broken stone as the aggregate, and the like in the prior art. The light aggregate comprises an aggregate core, wherein a middle layer is coated outside the aggregate core, and a shell layer is coated outside the middle layer. The production method comprise: adding cement and fly ash into a reel oscillating machine, adding water in a dropwise manner, and oscillating to form an aggregate core; spraying in the reel oscillating machine while adding a mixed material of cement and urea formaldehyde foam or polyphenyl foam powder to the reel oscillating machine to prepare a middle layer; spraying in the reel oscillating machine while adding a mixed material of cement and ash or carbon powder or polyphenyl foam powder to prepare a shell layer. The light aggregate of the present invention can be used for production of self-thermal insulation concrete, lightweight wall bricks, lightweight thermal insulation partition boards, and other interior wall and exterior wall materials.

Description

Technical field: [0001] The invention relates to a lightweight aggregate for making wall materials and a production method thereof. Background technique: [0002] At present, sand and crushed stone are mainly used as aggregates to make wall materials. The disadvantages are that the weight of the wall materials is heavy, and resources are exhausted in many places, and long-distance transportation costs are high. Invention content: [0003] The technical problem to be solved by the present invention is to provide a lightweight aggregate for composite, thermal insulation, and fire wall materials and its production method. The wall material made of it has the advantages of small weight, fire prevention, heat preservation, earthquake resistance, and environmental protection. Local materials can be obtained to save transportation costs. [0004] The above-mentioned purpose is achieved like this: it comprises the bone core that is made of cement and fly ash, the bone core is cov...
