Production process of thermal insulation wall plate for light fireproof building exterior wall

Abstract

Disclosed is a production process of a thermal insulation wall plate for a light fireproof building exterior wall. Firstly, a thermal insulation layer is placed between a pair of parallel truss-type steel wire mesh frames, steel mesh slant ribs are evenly distributed between the pair of parallel truss-type steel wire mesh frames, and the pair of parallel truss-type steel wire mesh frames with thethermal insulation layer are pressed into a protective connecting layer to ensure that the lower surface of the protective connecting layer expands into the gap between the thermal insulation layer and the truss-type steel wire mesh frame on the upper surface of the thermal insulation layer and into a thermal insulation layer groove in the upper surface of the thermal insulation layer. A fireprooflayer is evenly coated on the lower surface of the thermal insulation layer to ensure that the upper surface of the fireproof layer expands into the gap between the thermal insulation layer and the truss-type steel wire mesh frame on the lower upper surface of the thermal insulation layer and into a thermal insulation layer groove in the lower surface of the thermal insulation layer. Finally, a reinforcing layer is coated on the lower surface of the fireproof layer and is separated from a forming mold after dewatering and forming. The fireproofing effect and heat preservation effect are good.Due to the truss-type steel wire mesh frames, the pull-out resistance between all layers is guaranteed, and the strength performance of the wall plate is improved.

Description

technical field [0001] The invention relates to a thermal insulation material for the outer wall of a building, in particular to a production process of a light-weight thermal insulation wall panel for the outer wall of a fireproof building. Background technique [0002] Recently, incidents of building exterior wall insulation materials falling off and catching fire continue to occur. The disadvantages of the use of traditional building wall insulation materials have gradually become prominent. In addition, the country has higher and higher requirements for building energy-saving indicators, and the fire performance of building insulation materials needs to be strictly controlled. Under the requirements of national policies, new thermal insulation and energy-saving materials are bound to undergo a major technological update. At present, the existing building insulation methods mainly include the technology of adding thin mortar coating to the insulation layer. This method is...

AI Technical Summary

Problems solved by technology

At present, the existing building insulation methods mainly include the technology of adding thin mortar coating to the insulation layer. This method is to directly fix the insulation materials such as extruded plastic board and expanded polystyrene board on the building wall after the construction is completed. , and then use cement mortar to smear the surface, and finally complete the wall insulation of the building. The existing wall insulation technology requires secondary construction, poor fixing strength of the insulation material, easy to fall off, short service life, poor fire resistance, Insufficient heat preservation indicators and other disadvantages
