Problems solved by technology

[0002] For a long time, the comprehensive utilization of iron ore tailings has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of iron ore tailings at home and abroad, most of them have not been put into practice due to various technical and economic reasons. industrial realization
[0003] To sum up, it has been reported that iron ore tailings are used as auxiliary raw materials to produce cement, wall bricks, and road materials, but iron ore tailings are used as the main raw material for the production of aerated blocks.

Embodiment Construction

[0014] A method for producing a fireproof insulation board, the method includes the following steps:

[0015] 1) Take 5-8 parts of expandable polystyrene masterbatch particles and pre-foam them with steam, then mix the prefabricated flame retardant slurry and pre-foamed polystyrene particles in a weight ratio of 1:2-4 Mix evenly, then fully mix with 5-8 parts of Enteromorpha fiber, 25-35 parts of natron, 12-15 parts of expanded perlite, and put them into a ball mill for fine grinding. The particle size of the mixture is controlled at 5-10mm ;

[0016] 2) Mix and stir the dry mixture of the above step (1) with 50-60 parts of water and 5-7 parts of foaming agent, and form the slurry at a temperature of 65-75°C, and the foaming time is 30-40 minutes;

[0017] 3) Inject the foaming slurry into the forming mold and press to form a green body, the pressure is 40-60Mpa;

[0018] 4), drying, drying is divided into low temperature zone and high temperature zone, first enter the low t...

Abstract

The invention discloses a method for producing a fireproof heat-preservation board. The method comprises the following step: 1) performing steam pre-expansion on 5 to 8 parts by weight of expandable polystyrene master batch particles, uniformly mixing prepared flame retardant slurry and the pre-expanded polystyrene particles according to the weight ratio of 1: (2-4), fully mixing the mixture, 5 to 8 parts by weight of enteromorpha fibers, 25 to 35 parts by weight of water glass and 12 to 15 parts by weight of expanded perlite, and putting the mixture in a ball mill to be finely grinded, wherein the granularity of the mixture is controlled to be 5 to 10 mm. According to the method, a large amount of iron tailings are used, energy is saved, the environment is protected, the problem of environmental pollution caused by the stockpiling treatment of the iron tailings is mitigated, and meanwhile, a novel raw material is provided for a hollow brick.

Description

technical field [0001] The invention relates to the field of new building materials, and in particular belongs to a method for producing a fireproof heat preservation board. Background technique [0002] For a long time, the comprehensive utilization of iron ore tailings has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of iron ore tailings at home and abroad, most of them have not been put into practice due to various technical and economic reasons. industrial realization. [0003] In summary, there have been reports of using iron ore tailings as auxiliary raw materials to produce cement, wall bricks, and road materials, but there have been no reports about using iron ore tailings as the main raw material for the production of aerated blocks. Contents of the invention [0004] The object of the present invention is to provide a method for producing a fire-proof insulation board, which has simple process, low raw mater...
