In China, traditional exterior wall insulation materials, such as polyurethane and other insulation materials, are basically combustible materials. In practice, they are basically unsuccessful and have suffered heavy losses. The basic function of the external wall insulation board is to prevent fire and heat insulation. After practice, the aluminum silicate insulation material has been used to replace the traditional exterior wall insulation material.
Ceramic fiber exterior wall insulation board Features:
1. High compressive strength and long service life
2, easy to cut, easy to install, not easy to break
3, good resistance to wind erosion
4, uniform fiber distribution, stable performance
5, the surface is flat, accurate size
6, uniform structure, good overall
The specific preparation method: taking aluminum silicate fiber, adding inorganic binder, organic binder and additive, fully stirring, mixing and pulping, and then using mechanical extrusion molding or manual molding to produce the garment blank, after 100- Drying at 150 ° C removes moisture and causes the internal binder of the product to gel and harden to a desired hardness. The dried product is cut, ground, and drilled using mechanical equipment for further deep processing.
Compatibility of raw materials: The quality ratio of each component of this product is 40-60 ceramic fiber, 20-30 inorganic binder, 0.5-1.5 organic binder, 20-30 additive.
The ceramic fiber may be made of aluminum silicate fiber of different suitable temperature; the organic binder may be one or a mixture of polyacrylamide, cationic starch or methyl fiber; the inorganic binder is cement, silica sol, One or a mixture of one or more of aluminum sol or sodium silicate; the additive may be one or a mixture of one or more of silica powder, expanded silica powder, expanded perlite powder or silicon micropowder.
