Problems solved by technology

Although the external wall refractory and thermal insulation materials processed by polystyrene particles have thermal insulation properties, there are still many problems: such as poor construction difficulty, poor compatibility with inorganic materials, poor operability of quality control during construction, It leads to great difficulty in quality control; polyphenylene particles have light bulk density, low bond strength and compressive strength in actual construction, and mechanical properties are not easy to guarantee; in addition, polyphenylene particles are organic matter, with low fire protection rating, poor fire resistance, high temperature It is easy to produce harmful gases; the insulation mortar added with polyphenylene particles is not easy to recycle and will cause white pollution
[0004] In addition, in the existing fire-resistant and heat-insulating structures of external walls, the fire-proof layer and the heat-insulation layer are usually set separately. In the fire-proof layer or heat It is composed of thermal insulation mortar of beads. This kind of vitrified micro-bead mortar layer need
