A waterproof and fireproof insulation wall

Abstract

The invention discloses a waterproof, fireproof and thermal insulation wall. The raw materials include 350-400 parts of magnesium oxide, 150-200 parts of magnesium chloride, 4-5 parts of phosphoric acid, 10-15 parts of organic silicon waterproofing agent and 60-80 parts of expanded perlite. The invention has the following advantages: the magnesium oxychloride cement product is a product that can be recycled and comprehensively utilized as a resource, and is widely used in the construction industry due to its low price, high mechanical strength, good wear resistance, and excellent flame retardant performance. However, magnesium oxychloride cement products have the characteristics of poor water resistance and easy warping and deformation. When the silicone waterproofing agent is added, the MgCl2•6H2O in the slurry reacts more fully, reducing the moisture return of the product, and the reaction product forms a hydrophobic capillary channel, and the external moisture cannot enter the capillary channel, which greatly strengthens the magnesium oxychloride cement product. water resistance. Phosphoric acid can improve the stability of magnesium oxychloride cement hydrate in water. Expanded perlite not only has good thermal insulation and flame retardant effect, but also has good thermal insulation effect due to its porous characteristics.

Description

technical field [0001] The invention relates to the technical field of thermal insulation walls, more specifically, it relates to a waterproof and fireproof thermal insulation wall. Background technique [0002] Building thermal insulation is a measure to reduce the indoor heat of a building to be emitted to the outside. Measures are mainly taken from the building's external enclosure structure, which plays an important role in creating a suitable indoor thermal environment and saving energy. [0003] The patent with the notification number CN104761283B discloses a thermal insulation material for external walls. The thermal insulation material includes the following raw materials in parts by weight: 25-45 parts of slag Portland cement, 5-10 parts of fly ash, and 1-3 parts of foaming agent. parts, sodium silicate 0.1-0.7 parts, water 20-40 parts. Wherein, the foaming agent is a mixture of 30-70wt% dodecyl dimethyl amine oxide and 30-70wt% N-dodecyl glycol amine. [0004] Th...

AI Technical Summary

Problems solved by technology

[0004] This kind of external wall insulation material is mainly formed by the curing of Portland cement. Its function is relatively simple, and it only has the function of heat preservation.

Usually the outer wall also needs to have the function of fire prevention, but for the above-mentioned outer wall, it needs to be additionally coated with fireproof paint, which is more troublesome to operate and needs to be improved
