Problems solved by technology

The existing process of corrugated asphalt tiles is to press the texture of the substrate, and there is no focus on the effect of ceramic texture
At present, water-based paint surface spraying is used to treat the paint conjunctiva to obtain colorful colors. In the actual use process, it is found that this kind of surface decoration treatment scheme has poor weather resistance, and the paint film peels easily after being exposed to wind and sun. Fade, can not achieve the expected effect of the roof

preparation example Construction

[0030] The embodiment of the present application provides a method for preparing a corrugated asphalt tile, which includes: firstly setting an adhesive on the water-facing surface of the dried corrugated asphalt tile substrate to form a first glue layer, and then setting sintered colored sand on the surface of the first glue layer A colored sand layer is formed, and then an adhesive is placed on the surface of the colored sand layer to form a second adhesive layer.

[0031] The corrugated asphalt shingle base plate has a thickness of ≥3mm, a water absorption rate of ≤20%, an asphalt content of ≥40%, and a water content of ≤15%.

[0032] It should be noted that the thickness of the corrugated asphalt shingle substrate is selected according to the size and requirements of the corrugated asphalt shingle substrate.

[0033] In one embodiment of the present application, the corrugated asphalt shingle substrate has a thickness of 3mm. In some other embodiments of the present applic...

Embodiment 1

[0068] The embodiment of the present application provides a corrugated asphalt tile and its preparation method, which includes the following steps:

[0069] Select a corrugated asphalt tile substrate with a thickness of 3mm, a water absorption rate of ≤20%, an asphalt content of ≥40% and a water content of ≤15%. The amount of adhesive for the adhesive layer is 650g / m 2 , and then sprinkle dark red sintered colored sand with mesh number of 40-120 on the surface of the first glue layer to form a colored sand layer, and the amount of sintered colored sand to form the colored sand layer is 1500g / m 2 , and then coated with acrylic emulsion on the surface of the colored sand layer to form a second adhesive layer to obtain a preform, the amount of adhesive used to form the second adhesive layer is 350g / m 2 , the preform was dried at 150°C for 4 hours to obtain corrugated asphalt tiles, such as figure 2 shown.

Embodiment 2

[0071] The embodiment of the present application provides a corrugated asphalt tile and its preparation method, which includes the following steps:

[0072] Select a corrugated asphalt tile substrate with a thickness of 3mm, a water absorption rate of ≤20%, an asphalt content of ≥40% and a water content of ≤15%. The amount of adhesive for the adhesive layer is 650g / m 2 , and then sprinkle dark red sintered colored sand with mesh number of 40-120 on the surface of the first glue layer to form a colored sand layer, and the amount of sintered colored sand to form the colored sand layer is 1500g / m 2 , and then coated with acrylic emulsion on the surface of the colored sand layer to form a second adhesive layer to obtain a preform, the amount of adhesive used to form the second adhesive layer is 350g / m 2 , place the prefab in a rainproof place to dry naturally, and make corrugated asphalt tiles.

Abstract

The invention provides a waveform asphalt shingle and a preparation method thereof, and belongs to the technical field of building waterproofing. The preparation method of the waveform asphalt shingle comprises the following steps: firstly, arranging an adhesive on the upstream face of a dried waveform asphalt shingle substrate to form a first adhesive layer, then arranging sintered color sand on the surface of the first adhesive layer to form a color sand layer, and then arranging an adhesive on the surface of the color sand layer to form a second adhesive layer. The sintered color sand is attached to the upstream face of the waveform asphalt shingle base plate, so that the waveform asphalt shingle can obtain the target color, and the waveform asphalt shingle can have the ceramic texture and meet the aesthetic appreciation of the public. More importantly, under triple protection of the first adhesive layer, the colored sand layer and the second adhesive layer, the waveform asphalt shingle can effectively resist ultraviolet rays, the weather resistance of the waveform asphalt shingle is improved, and the service life of the waveform asphalt shingle is greatly prolonged. In addition, the color sand layer can keep color for a long time under the protection of the second glue layer.

Description

technical field [0001] The present application relates to the technical field of building waterproofing, in particular to a corrugated asphalt tile and a preparation method thereof. Background technique [0002] Corrugated asphalt shingle is a new type of building material imported from abroad. At present, there are very few domestic manufacturers of this material above designated size, so there is no own implementation standard yet. Because the tile has many advantages such as light weight, earthquake resistance, ventilation and dehumidification, waterproof and breathable, sound insulation and heat insulation, weather resistance and anticorrosion, it is widely used in various roof projects such as houses, schools, villas, industrial plants and agricultural houses. Under the initiative of safe building and environmental protection building, this kind of tile has a broader development space. [0003] Corrugated asphalt tiles are mainly made of mineral fibers and plant fibers...
