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

Embodiment 1

[0068] refer to figure 1 , which is a flow process of a stone anti-beating process with an insulation board added to the present invention, comprising the following steps:

[0069] Step (1), the preparation of adhesive, is as follows:

[0070] Add 120kg of epoxy acrylic resin to a 200L stirred tank, stir at a speed of 250r / min, add 10kg of thickener, 25kg of filler, 3kg of polyvinyl alcohol, 2kg of methyl hexahydrophthalic anhydride and 0.4kg of bilirubin while stirring , Stir and mix evenly to obtain the adhesive.

[0071] In this embodiment, the epoxy acrylic resin of Beijing Gaomeng New Materials Co., Ltd. is used.

[0072] In this embodiment, the filler is uniformly mixed with 9kg of calcium carbonate, 12kg of titanium dioxide and 4kg of zinc oxide.

[0073] Step (2), bonding the insulation board, is as follows:

[0074] The adhesive prepared in step (1) is evenly coated on the back of the stone board, and then the insulation board with the same size as the stone board...

Embodiment 2

[0090] The difference with embodiment 1 is:

[0091] The consumption of each component that adds in the step (1) is as follows:

[0092] 125kg of epoxy acrylic resin; 5kg of thickener; 30kg of filler; 1kg of polyvinyl alcohol; 1kg of methyl hexahydrophthalic anhydride; 0.3kg of bilirubin.

[0093] Among them, the filler is uniformly mixed with 16kg of calcium carbonate, 4kg of titanium dioxide and 10kg of zinc oxide.

Embodiment 3

[0095] The difference with embodiment 1 is:

[0096] The consumption of each component that adds in the step (1) is as follows:

[0097] 130kg of epoxy acrylic resin; 7.5kg of thickener; 20kg of filler; 2kg of polyvinyl alcohol; 1.5kg of methyl hexahydrophthalic anhydride; 0.5kg of bilirubin.

[0098] Among them, the filler is uniformly mixed with 8kg calcium carbonate, 9kg titanium dioxide and 3kg zinc oxide.

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...
