[0044] The adhesive has a main component and a primary component, the main component is vinyl acetate acrylic emulsion (VINYL ACETATEACRYLATE COPOLYMER) and acrylic copolymer (ACRYLIC COPOLYMER), the secondary component is hydrophilic polyvinyl acetate (AQUEOUS POLYVINYL ACETATE) ;

[0045] The weight percent of the adhesive is 85, the weight percent of the main component is 70, the weight percent of the secondary component is 15, the weight percent of the aqueous solution is 10, and the viscosity of the waterproof coating is 21cps;

[0046] The desiccant is ethanol;

[0047] The waterproof coating is sprayed after stirring and entraining air to reach a porosity of 20-30%.

[0048]The autoclaved aerated concrete slab structure of this embodiment, in the specific application process, when the autoclaved aerated concrete slab 2 is installed vertically as an exterior wall panel, the plate ends at the joints connecting the transverse joints should keep the steps low on the outside and high on the inside. When the water climbs and seeps in along the lower steps outside, when the seepage volume and water pressure are not very large, it will be blocked at the step surface, and then return along the lower steps and flow out of the wall, thus improving the original structure. Water-repellent effect with horizontal seams.

[0049] Example 2

[0050] The basic structure of the autoclaved aerated concrete slab structure of this embodiment is the same as that of Embodiment 1. The difference and improvement lies in that the beam 6 is an I-shaped steel beam, and the upper surface thereof is fixed with a rivet 61, which is fixed to the floor 7 by the rivet 61. connect. The floor slab 7 is tightened by the I-beam, and the floor slab 7 is close to the connecting transverse joint to avoid water seepage. The inner wall of the autoclaved aerated concrete slab 2 is also fixed with two angle steels 5 distributed up and down, and the upper angle steel 5 is attached to the connecting transverse joint formed by the two autoclaved aerated concrete slabs 2, and supported on the bottom of the floor 7, The bottom angle steel 5 is supported on the bottom of the I-beam beam. Improve the stability of I-beam fixing. The surface of the concrete slab is sprayed with waterproof paint, and its proportion is as follows

[0051] The waterproof coating includes an adhesive, an aqueous solution, and a desiccant, wherein the adhesive has a weight percentage of 70-80, the aqueous solution has a weight percentage of 5-15, and the desiccant has a weight percentage of 5. 10 parts of rubber powder, the particle size of which is not greater than 1 mm; adjusting the weight percentage of the adhesive and the aqueous solution so that the weight percentage of the waterproof coating reaches 100;

[0053] The weight percent of the adhesive is 85, the weight percent of the main component is 70, the weight percent of the secondary component is 15, the weight percent of the aqueous solution is 10, and the viscosity of the waterproof coating is 21cps;

[0054] The desiccant is ethanol;

[0055] The waterproof coating is sprayed after stirring and entraining air to reach a porosity of 20-30%.

[0056] Example 3

[0057] The basic structure of the autoclaved aerated concrete slab structure of this embodiment is the same as that of the embodiment 2, the difference and improvement lies in that two angle steels 5 are fixed on the inner wall of the autoclaved aerated concrete slab 2 through two bolts 1 . To improve the fixed stability of the angle steel 5. The connection between the floor 7 and the autoclaved aerated concrete slab 2 is filled with fine stone concrete caulking 8 , and the floor 7 and the autoclaved aerated concrete slab 2 are connected together through the transition of the fine stone concrete slab 8 . The connection between the fine stone concrete caulking 8 and the autoclaved aerated concrete slab 2 is filled with an elastic material caulking 9, which acts as a buffer to avoid and reduce stress changes on the floor 7 due to environmental changes. The surface of the concrete slab is sprayed with waterproof paint, and its proportion is as follows
