Embodiment Construction

[0027] The specific implementation steps of the process of the present invention are as follows:

[0028] 1. Ingredients

[0029] Cement and fly ash are automatically measured and added to the mixer according to the preset ratio. Foaming agent, fiber and waterproofing agent are manually measured and put into the mixer. Water is automatically added to the mixer after being measured by the flow meter.

[0030] 2. Stirring

[0031] The materials added to the mixer will form a high-temperature air pressure state in the mixer in a closed space, so that the stirred materials will form a puffed state, and the uniformity and fusion of the raw materials will be improved. Stir the materials in the mixer for about 3 minutes until they are uniform. .

[0032] 3. Pouring molding

[0033] While the slurry is being stirred, the mold is moved to the discharge port below the mixer through the track. The slurry is evenly stirred and poured into the mold. After the pouring is completed, it is...

Abstract

The invention provides a novel fireproof cement foamed thermal-insulation material for an exterior wall. The novel fireproof cement foamed thermal-insulation material comprises, by mass, 63% of cement, 30% of fly ash, 4% of a foaming agent, 0.8% of a waterproof agent, 0.5% of fiber, 1.7% of an accelerator and 2 to 5% of slag. A production process for the material comprises the following steps: batching; stirring; pouring and molding; foaming; cutting; and packaging. The novel fireproof cement foamed thermal-insulation material has the advantages of long service life, reduction in production cost due to utilization of a great amount of industrial waste materials, strong bonding force with cement and good fireproof performance.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials for external walls, in particular to a novel fireproof cement foam thermal insulation material for external walls and a production process thereof. Background technique [0002] The main thermal insulation materials of the traditional external wall insulation system are polystyrene board (EPS) and extruded polystyrene board (XPS). The unprecedented performance has attracted great attention from all walks of life in the industry. During the combustion process of these materials, the molten droplets and toxic smoke are continuously produced, and the chlorofluorocarbons, hydrofluorocarbons, freons and other gases released at the same time can not be ignored. The harm to the environment, and also to the human body, is very environmentally friendly . For this reason, the Ministry of Housing and Urban-Rural Development and the Ministry of Public Security jointly issued the "Interim Provisio...
