Description

Technical Field

[0001] The utility model specifically relates to a spray quick-setting rubber asphalt waterproof coating structure, and belongs to the technical field of spray quick-setting rubber asphalt waterproof coating. Background Art

[0002] Spray quick-setting rubber asphalt waterproof coating (SQRA) is a coating composed of two components: curing agent and rubber asphalt emulsion. The two components are placed in storage barrels respectively. Under normal temperature, a special nozzle is used to spray the two components onto the base layer at a certain angle. The two components are processed by the nozzle in an instant atomized form and cross-mixed in a fan shape. The rubber asphalt emulsion forms a dense and complete waterproof coating film in an instant demulsification manner under the action of the curing agent. The asphalt molecules in the coating film penetrate and interweave to form a continuous mesh solid. After spraying, the waterproof coating can be tightly adhered to the base layer to achieve a "skin-like" waterproof effect. Existing spray A quick-setting rubber asphalt waterproof coating spraying structure, such as the Chinese patent authorization announcement number: CN218176409U, discloses a spray quick-setting rubber asphalt waterproof coating structure, which is provided with a first waterproof layer and a second waterproof layer in sequence on the upper part of the cement base, so that under the joint action of the first waterproof layer and the second waterproof layer, the waterproof performance of the cement base can be greatly improved, but the bonding force between the layers of the structure is general, and the coating and the base layer are easily peeled off after spraying, and the coating layers are peeled off from each other; in addition, when the existing spray quick-setting rubber asphalt waterproof coating is sprayed onto the base layer, it is necessary to adjust the nozzle angle to achieve the cross-mixing of the two components, but the mixing effect of the waterproof coating cannot be understood.

[0008] During construction, the base layer is cleaned first, and then the interface layer is coated on the base layer. After the interface layer is coated, the curing base layer, the rubber asphalt emulsion spray layer and the curing top layer are sprayed; the curing agent is sprayed onto the interface layer at an angle lower than 30° to form a curing base layer, and then the rubber asphalt emulsion and the curing base layer are sprayed onto the curing base layer at an angle of 60 to 90°, and the rubber asphalt emulsion impacts the curing base layer to form a rubber asphalt emulsion spray layer; and when spraying the rubber asphalt emulsion, the curing agent is sprayed simultaneously, and the fan-shaped atomized surface formed by the curing agent and the rubber asphalt emulsion intersects to form a curing top layer; the spraying intersection of the curing base layer, the rubber asphalt emulsion spray layer and the curing top layer is located on the top surface of the interface layer; when the base coat and the sprayed quick-setting rubber asphalt coating are cured, a dense sprayed quick-setting rubber asphalt waterproof coating structure can be formed on the base layer.

[0010] Furthermore, the spray marking layer is arranged at the initial spraying stage of the cured bottom layer, the cured top layer and the rubber asphalt emulsion spray layer; during spraying, the pump group first draws the spray liquid from the marked curing agent storage barrel and the rubber asphalt emulsion storage barrel, and sprays it through the nozzle, and after adjusting the nozzle opening and inclination angle to reach the appropriate position, the pump group is switched to the conventional curing agent storage barrel and rubber asphalt emulsion storage barrel.

[0011] Furthermore, the spray marking layer is composed of three different pigments, and the cured bottom layer, cured top layer and rubber asphalt emulsion spray layer are respectively mixed with a pigment; by observing the distribution of the three pigments, the distribution status between the cured bottom layer, cured top layer and rubber asphalt emulsion spray layer can be obtained.

[0013] Furthermore, the base coating layer also includes a structural support layer, the structural support layer includes a roller-coated waterproof coating applied on the interface layer, a non-woven fabric layer is laid on the roller-coated waterproof coating, a rubber asphalt coating is coated on the non-woven fabric layer, the solidified base layer is sprayed on the top surface of the rubber asphalt coating, the structural support layer uses the roller-coated waterproof coating as the base layer, the non-woven fabric as the middle layer, and the rubber asphalt coating as the top layer. After the rubber asphalt coating is applied, before the rubber asphalt coating is cured, the solidified base layer is sprayed onto the rubber asphalt coating, and the curing agent can be tightly combined with the rubber asphalt coating. Then, the quick-setting rubber asphalt coating is sprayed, so that the rubber asphalt coating, the solidified base layer, the rubber asphalt emulsion spray layer and the solidified top layer can be composited into an integrated structure.

[0014] Furthermore, the structural support layer is arranged at the splicing position and the pipe penetration position of the base layer; the rubber asphalt coating extends outward from the center of the splicing position or the pipe penetration position to form a slope surface. The structural support layer is arranged at the splicing position or the pipe penetration position, which can increase the structural strength at the splicing position or the pipe penetration position, and prevent the splicing position or the pipe penetration position from tearing and causing waterproofing failure. The outer edge of the structural support layer is a slope structure, which can make the sprayed quick-setting rubber asphalt coating and the structural support layer transition smoothly.

[0015] Compared with the prior art, the spray-coated quick-setting rubber asphalt waterproof coating structure of the utility model adopts a base layer and a primer layer to ensure the bonding degree between the coating and the base layer, and prevent the coating and the base layer from peeling off due to the peeling particles of the base layer. The spray-coated quick-setting rubber asphalt coating is sprayed on the dense primer layer to ensure its strong adhesion with the primer layer. The solidified base layer, the rubber asphalt emulsion spray layer and the solidified top layer form a sandwich structure, which can realize the rapid coagulation of the rubber asphalt emulsion spray layer on the surface of the primer layer to form a dense and complete waterproof coating film. The asphalt molecules in the coating film penetrate and interweave with each other to form a continuous network of coagulated bodies. In addition, it can assist in monitoring the mixing effect of the curing agent and the rubber asphalt emulsion, and can provide a reference for adjusting the nozzle angle to ensure that the rubber asphalt emulsion and the curing agent are fully mixed, so that under the action of the curing agent, a dense and complete waterproof coating film is formed in an instant demulsification manner.
