A kind of counter-beating process of stone with insulation board

Abstract

The present invention relates to the technical field of prefabricated stone concrete hanging slabs, and relates to a stone back-beating process with an insulation board, which includes the following steps: step (1), preparation of adhesive; step (2), bonding Insulation board; step (3), installing anchors; step (4), coating interface agent; step (5), coating release agent; step (6), laying composite board; step (7), pouring concrete; Step (8), remove the template; step (9), cleaning; wherein, the adhesive includes the following components in parts by mass: 120-130 parts of epoxy acrylic resin; 5-10 parts of thickener; 20-30 parts of filler 1-3 parts of polyvinyl alcohol; 1-2 parts of methyl hexahydrophthalic anhydride; 0.3-0.5 parts of bilirubin. The invention has the effect of improving the aging resistance of the adhesive and making the stone board more difficult to fall off.

Description

technical field [0001] The invention relates to the technical field of prefabricated anti-beating stone concrete hanging boards, in particular to a stone anti-beating process with an insulation board added. Background technique [0002] The stone counter-beating process is to beat the decorative stone for the exterior wall of the building into the concrete in the factory in advance to form an integrated building prefabricated component, which can improve the accuracy of the stone position, make the stone on the surface of the prefabricated component more regular, and make the stone The attachment is more firm, and the construction progress of the overall assembly of prefabricated components can be improved. [0003] At present, with the rapid development of the economy, people's living standards are getting higher and higher, and people's requirements for buildings are getting higher and higher. In addition to creating the decorative style of the building's exterior walls, i...

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: since the prefabricated anti-beating stone concrete hanging panels are mostly used on the exterior walls of buildings, they often need to withstand the wind, the sun and the rain, so that the adhesive between the stone and the insulation board is vulnerable to damage. Heat, light, oxygen, etc. can easily cause the polymer molecular chain to break, which may cause discoloration, cracking, and brittleness of the adhesive, which will affect the bonding strength and tensile strength of the adhesive. It may even cause the stone to separate from the insulation board and fall off, which will affect pedestrians or traffic. Therefore, there is still room for improvement
