Abstract

The invention discloses a preparation device and method for fly-ash-based mineral polymer thermal insulation materials, and belongs to the technical filed of building materials. According to the invention, polyethylene foam plastic is adopted as a plastic product additive; a mineral polymer thermal insulation material prepared from the material has a higher intensity than polystyrene series organic insulation materials; the adopted fly ash and silica fume are inorganic materials, and have good fireproof performance, by using the strong activity of the silica fume, the reaction rate of less active fly ash under alkaline conditions is increased, maintenance conditions such as temperature and humidity are not required in the production preparation process, which can directly take place at room temperature. The thermal insulation material prepared by the method disclosed by the invention has the advantages of good fireproof performance, thermal insulation performance, and a simple preparation maintenance process. An automatic timing stirring tank designed by the invention is provided with an emulsifying head inside, and the emulsifying head can effectively enhance the stirring effect of mineral polymer mixed slurries.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation device and method for a fly ash-based mineral polymer thermal insulation material. Background technique [0002] Geopolymeric materials are three-dimensional aluminosilicate mineral polymers containing various amorphous to semicrystalline phases, with both amorphous and quasi-crystalline characteristics. Mineral polymer materials have the advantages of high strength, fast hardening, strong acid and alkali resistance, low permeability, low shrinkage rate and expansion rate, high temperature resistance, wide range of raw material sources and simple preparation process, which make them widely used in many aspects. Such as building materials, civil engineering, chemical industry, environmental protection, etc., the application prospects are broad. [0003] With the rapid development of my country's economy and the development and utilization of mineral resou...
