Abstract

The invention relates to a production method producing low temperature ceramic foam material by using solid waste slag, which belongs to the technical field of building materials. Combined according to the mass ratio, the components of the low temperature ceramic foam materials consist of 100 portions of cementing materials, 100 to 400 portions of skeletal materials, 13 to 50 portions of activators, 0.2 to 3.0 portions of accessory ingredient, 0.04 to 1.0 portions of foaming agents and 15 to 50 portions of solvents. By the processes of raw material treatment, mixing, casting molding and maintenance, the raw materials with the formulas are made into the low temperature ceramic foam material which takes low temperature ceramic compound reinforced by inorganic waste slag particles as matrix phase and stomas as dispersed phase. Compared with the prior art, the material produced by the method has the advantages of high strength, good thermal and heat insulating property, high waste slag utilization ratio, low cost, environmental protection and saving natural resources, etc., which can be widely used as decoration material and thermal and heat insulating material.

Description

1. Technical field: [0001] The invention relates to a low-temperature ceramic foam material and a production method thereof, belonging to the technical field of building material preparation. 2. Background technology: [0002] Foam materials have broad application prospects in the national economy because of their excellent properties such as low density, excellent insulation performance, material saving, and high specific strength. According to the characteristics of the bulk material that constitutes the foam material, there are roughly the following categories: foam plastic, foam glass, foam ceramics, foam concrete (including aerated concrete), and foam metal. The low-temperature ceramic foam material produced from solid waste belongs to the same inorganic non-metallic foam material as foam glass, foam ceramics, and foam concrete, but they are obviously different in terms of raw material composition and process. [0003] Foam glass is made of waste glass as the main raw ...
