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 needs additives such as mortar and cement, and needs to be aired, dried, and requires special maintenance; specifically, this type of vitrified micro-bead mortar layer has a high density. Construction It is inconvenient to carry in the middle; and as the fireproof layer of the outer wall, the thickness cannot meet the fire protection requirements; after the production and processing are completed, it needs 7 to 15 days of maintenance, and the production and processing cycle is long; there will also be that the insulation layer and the fireproof layer are not firmly bonded and easy to fall off And other issues
[0005] In addition to the above technologies, there are also expanded vitrified beads as lightweight aggregates, phenolic resin or emulsified asphalt or polyacrylonitrile as a binder to form a fireproof insulation layer through mold molding and sintering. This fireproof insulation layer needs to be compared with 100 parts of expanded vitrified glass is 50-200 parts of binder, resulting in limited content of expanded vitrified microspheres in the thermal insulation layer, and also requires a sintering process
