Wind-resistant metal rock wool composite plate for external wall thermal insulation

Abstract

The invention relates to the technical field of metal rock wool composite plate manufacturing, and discloses a wind-resistant metal rock wool composite plate for external wall thermal insulation. An outer side steel plate and an inner side steel plate are used as inner and outer layers of a base material, magnetite, mica powder, manganese steel and chromium carbide alloy are added into a four-roller centrifugal machine for high-speed solidification processing into a composite plate blank after high-temperature smelting, the composite plate blank is soaked in a composite resin liquid to form apreliminary rock wool layer, the inner and outer layers of the base material and the preliminary rock wool layer are sequentially placed into a composite machine to form a whole, and the wind-resistant metal composite plate is prepared. By means of the combination of the magnetite, the mica powder, the manganese steel and the chromium carbide alloy, the performance requirements of the rock wool composite plate are improved, by means of the combination of polyvinyl chloride, epoxy resin and polystyrene, the compactness among all plate layers is optimal, the internal structure is prevented fromgenerating gaps, damage caused by outside wind is avoided, and the integral structural strength is not affected while the wind resistance of the rock wool composite plate is improved.

Description

technical field [0001] The invention relates to the technical field of metal rock wool composite board manufacturing, in particular to a wind-resistant metal rock wool composite board used for external wall heat preservation. Background technique [0002] The metal rock wool composite board uses color-coated steel plates as the inner and outer layers, and the core material uses rock wool composite boards. The rock wool uses high-quality natural rocks as the main raw materials, such as basalt, gabbro, dolomite, etc. Appropriate amount of binder is solidified by high-speed centrifugation into fibers after high-temperature smelting. It is an ideal material that is economical and has good thermal insulation effect. [0003] The metal rock wool composite board still has a series of defects such as large gaps and poor compactness. After being subjected to external wind force, the internal structure of the composite board will fall off. At the same time, the adhesive will always o...

Problems solved by technology

[0003] The metal rock wool composite board still has a series of defects such as large gaps and poor compactness. After being subjected to external wind force, the internal structure of the composite board will fall off. At the same time, the adhesive will always overflow during the composite process, resulting in waste, resulting in low overall performance of the metal rock wool composite board. Therefore, a wind-resistant metal rock wool composite board for external wall insulation is provided.
