Expanded and vitrified micro-bead thermal insulation board and manufacturing method thereof

Abstract

The invention discloses a manufacturing method of an expanded and vitrified micro-bead thermal insulation board. The manufacturing method comprises the following steps of: dry mixing; wet mixing; automatic distribution; die-casting; automatic demoulding; natural curing; steam curing; and drying. The invention also discloses an expanded and vitrified micro-bead thermal insulation board manufactured by using the manufacturing method. By using the expanded and vitrified micro-bead thermal insulation board and the manufacturing method thereof provided by the invention, the production process is simplified, the producing and curing periods are shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the manufacturing technology of thermal insulation materials for building walls, in particular to an expanded vitrified microbead thermal insulation board and a manufacturing method thereof. Background technique [0002] As a substitute product of expanded perlite, expanded vitrified microspheres not only inherit the advantages of expanded perlite in heat preservation, fire prevention, and environmental protection, but also overcome the disadvantages of expanded perlite, such as high water absorption, low strength, and poor fluidity. Therefore, the thermal insulation mortar made of expanded vitrified microspheres has excellent characteristics such as light weight, heat insulation, fire prevention, high and low temperature resistance, anti-aging, and low water absorption, and can replace fly ash floating beads, glass The application of many traditional lightweight aggregates such as microbeads, expanded perlite, polystyrene part...

AI Technical Summary

Problems solved by technology

However, due to the practical application of thermal insulation mortar with expanded vitrified microbeads, there are problems such as low entry threshold, serious shoddy vitrified microbeads, and loss of control of quality supervision leaks, resulting in thermal insulation of expanded vitrified microbeads Mortar quality is unstable, resulting in continuous quality and safety accidents

Therefore, there is a potential safety hazard in the expansion vitrified microbead insulation board in the prior art

In addition, there are problems in the manufacture of expanded vitrified bead insulation boards, such as difficulty in fabric distribution, difficulty in demoulding, and difficulty in maintenance. Therefore, it is difficult to guarantee the efficiency and cycle of production, resulting in excessive production costs, low efficiency, and long cycles.
