Preparation method of ultra-light foamed concrete composite thermal insulation material

Abstract

The invention discloses a preparation method of an ultra-light foamed concrete composite thermal insulation material. The method specifically comprises the following steps: preparing slurry; adding slurry into two storage bins of thermal insulation material processing equipment,pouring the two storage bins into a mold by corresponding discharging pipes respectively, driving a movable supporting plate by a movable motor to move, enabling the movable supporting plate to drive a scraping plate to move while moving, and scraping the poured slurry to be flat through the scraping plate; and puttingthe mold and the slurry into an aging chamber for curing to obtain the novel ultra-light foamed concrete composite thermal insulation material. According to the composite thermal insulation material,the overall density is reduced while the strength of the composite thermal insulation material is guaranteed, the composite thermal insulation material is lighter, the production cost is reduced, dispersed pouring can be conducted in a mold, slurry accumulation and workload increase caused by concentrated pouring at one point are avoided, working efficiency is high. The thermal insulation materialprocessing equipment can be matched with molds with different depths for processing, and is high in applicability.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a preparation method of an ultra-light foamed concrete composite thermal insulation material. Background technique [0002] Foamed concrete, also known as foamed concrete or lightweight concrete, foamed concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and mix the foam and cement slurry evenly, and then pass through the foaming machine It is a new type of lightweight thermal insulation material containing a large number of closed pores formed by natural curing through the pumping system for cast-in-place construction or mold molding; foamed concrete is made by mixing foaming agent, cement, fly ash, stone powder, etc. The double-set continuous structure polymer of the organic binder contains uniform pores; the foamed concrete is used for roof insulation slope, ground insulation cushion, upturned beam foundation pit filling, ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a preparation method of an ultra-light foamed concrete composite thermal insulation material. The present invention adds silicon carbide powder and ethanol to the preparation raw materials of the modified auxiliary agent to form an airgel through replacement. After mixing, it is evenly distributed and plays a role of connection in the raw materials, making the composite thermal insulation material relatively light. By adding ceramic fibers to the raw materials for the preparation of the composite thermal insulation material, the overall strength of the composite thermal insulation material is enhanced. The composite thermal insulation material While ensuring its own strength, it reduces its overall density and makes it lighter. At the same time, it reduces the amount of cement, fly ash, lime powder and foaming agent, which effectively reduces production costs and solves the problem of low strength of traditional composite insulation materials. , technical problems with high production costs;
