Embodiment 1

[0024] Prepare modified asphalt by the following method: add 30g of natural lake asphalt to 70g of AH90# petroleum asphalt, heat up to 170°C, add 5g of thermoplastic elastomer SBS4402 and 5g of polypropylene, heat up to 185°C to 195°C, start the colloid Grinding, homogenization time is 2 hours; add 90g montmorillonite, keep the temperature at 180°C ~ 185°C, stir for 1 hour, then add 0.15g of ultraviolet absorber, stir for 0.5h, and then make modified asphalt for asphalt shingles. Then the modified asphalt shingle is prepared by the asphalt shingle forming system.

[0025] The mineral aggregates used are basalt aggregates, the glass fiber felt is alkali-free 300# glass fiber felt, and the isolation material layer is PP isolation film.

Embodiment 2

[0027] Prepare modified asphalt by the following method: add 50g of natural lake asphalt to 50g of AH90# petroleum asphalt, heat up to 170°C, add 4g of thermoplastic elastomer SBS4402 and 4.5g of polypropylene, heat up to 185°C to 195°C, start Colloid grinding, homogenization time is 2 hours; add 60g montmorillonite, keep the temperature at 180℃~185℃, stir for 1 hour, then add 0.08g ultraviolet absorber, stir for 0.5h, and then make modified asphalt for asphalt tiles , and then the modified asphalt shingle is prepared by the asphalt shingle forming system.

[0028] The mineral aggregates used are basalt aggregates, the glass fiber felt is alkali-free 450# glass fiber felt, and the isolation material layer is PET isolation film.

Embodiment 3

[0030] Prepare modified asphalt by the following method: add 70g of natural lake asphalt to 30g of AH90# petroleum asphalt, heat up to 170°C, add 3g of thermoplastic elastomer SBS4402 and 3.5g of polypropylene, heat up to 185°C to 195°C, start Colloid grinding, homogenization time is 2 hours; add 90g of montmorillonite, keep the temperature at 180℃~185℃, stir for 1 hour, then add 0.05g of ultraviolet absorber, stir for 0.5h, and then make modified asphalt for asphalt tiles , and then the modified asphalt shingle is prepared by the asphalt shingle forming system.

[0031] The mineral aggregates used are granite aggregates, the glass fiber felt is alkali-free 3 () (0# glass fiber felt, and the isolation material layer is LDPE isolation film.

[0032] The modified asphalt for asphalt shingles obtained in the above preparation process was first aged in a film oven (TFOT, temperature 163°C, time 5h), and then indoor accelerated ultraviolet aging test (125W high pressure mercury lam...

Abstract

The invention discloses an asphalt tile. The asphalt tile is of a multilayer structure, and consists of a mineral particle layer, a glass fiber felt, modified asphalt coating layers and an isolation material layer from top to bottom, wherein the mineral particle layer and the glass fiber felt are arranged on the upper surface, the modified asphalt coating layers are arranged at the two surfaces of the glass fiber felt, and the isolation material layer is arranged on the lower surface. The asphalt tile has the advantages that the good mineral particle adhering performance, anti-aging performance and flame-retardant performances are realized; the asphalt tile can be applied to various types of building roofs, especially the slope roofs of civil houses and villas.

Description

technical field [0001] The invention relates to an asphalt tile, which belongs to the field of building materials. technical background [0002] Asphalt shingles have dual functions of decoration and waterproofing, so using them for roof renovation has the advantage of a short cycle. In China, asphalt tiles have been developed since the 1980s, and are recognized by many builders and residents in view of their decoration, waterproof, environmental protection, light weight, and convenient construction. [0003] The petroleum asphalt used in existing asphalt shingles is prone to aging, which causes the mineral particles on the surface of the product to fall off easily, has poor aging resistance, and has a short service life, which affects the application of asphalt shingles. Contents of the invention [0004] In view of the above-mentioned defects, the purpose of the present invention is to provide an asphalt shingle that can prolong the service life, improve the aging resis...
