Description

Technical Field

[0001] The invention belongs to the technical field of building materials, and in particular relates to a waterproof coiled material and a preparation method and application thereof. Background Art

[0002] At present, the waterproofing membranes we use are mainly SBS asphalt waterproofing membranes, but asphalt has environmental safety issues during production, construction, and use. The hot melt construction of asphalt-based waterproofing membranes and the heating construction process of non-curing asphalt-based waterproofing coatings will produce smoke and unpleasant odors with strong carcinogens, and often cause safety accidents such as fires. In addition, asphalt-based waterproofing materials are not corrosion-resistant. When used in underground projects, they will cause very large pollution to groundwater, produce strong carcinogens, and endanger the life safety of humans, animals and plants for a long time. However, due to price and usage habits, SBS asphalt membranes and non-curing asphalt-based waterproofing coatings are still used on a large scale. In theory, asphalt is not an aging-resistant material. No matter how it is modified, it is impossible to fundamentally change and improve the aging resistance of the product, and it is even more impossible to produce a waterproof material with a service life of 70 years. Therefore, providing an environmentally friendly, safe, and long-life waterproofing membrane has great application prospects. Summary of the invention

[0003] The present application provides a waterproof roll material and a preparation method and application thereof, aiming to solve the problems of existing waterproof roll materials having high pollution, safety issues during use and short service life.

[0095] The test method for the membrane-to-membrane peel strength described in this application is GB / T 328.21-2007 Test methods for building waterproof membranes Part 21: Peeling properties of polymer waterproof membrane joints

[0096] It can be seen from Table 1 that the waterproof roll material described in the present application is modified and toughened by using SBS rubber, so that the sheet has good elastic recovery rate, heat resistance and low-temperature bending property, and the sheet has good tensile property and flame retardant property by using chlorinated polyethylene. The sheet-to-sheet seam peeling strength is greatly improved by using MS self-adhesive layer. The 3.0 mm thick polymer composite roll material greatly improves the service life of a waterproof roll material.

[0097] The preparation method of the waterproof roll described in Comparative Example 1 is different from that in Example 1 only in that the raw material SBS thermoplastic rubber is not added during the preparation of the surface layer in the preparation method of the waterproof roll described in Comparative Example 1, resulting in a decrease in the elastic recovery rate, low temperature bending resistance, and heat resistance of the waterproof roll compared with Example 1.

[0098] The preparation method of the waterproof roll described in Comparative Example 2 is different from that in Example 1 only in that the raw material SBS thermoplastic rubber is not added during the preparation of the self-adhesive layer in the preparation method of the waterproof roll described in Comparative Example 2, resulting in a decrease in the peeling performance and heat resistance of the waterproof roll compared to Example 1.

[0099] The preparation method of the waterproof roll described in Comparative Example 3 is different from that in Example 1 only in that in the preparation method of the waterproof roll described in Comparative Example 3, the amount of chlorinated polyethylene added during the preparation of the surface layer is 20 parts. As a result, the maximum tensile force and flame retardant performance of the waterproof roll are lower than those of Example 1, while the elastic recovery rate is improved compared with that of Example 1.

[0100] The preparation method of the waterproof roll described in Comparative Example 4 is different from that in Example 1 only in that: in the preparation method of the waterproof roll described in Comparative Example 4, the amount of chlorinated polyethylene added during the preparation of the surface layer is 80 parts. As a result, the maximum tensile force of the waterproof roll is increased compared with that in Example 1, while the elastic recovery rate is decreased compared with that in Example 1.

[0101] The preparation method of the waterproof roll described in Comparative Example 5 is different from that in Example 1 only in that in the preparation method of the waterproof roll described in Comparative Example 5, the amount of SBS thermoplastic rubber added during the preparation of the surface layer is 8 parts. As a result, the elastic recovery rate, low temperature bending resistance and heat resistance of the waterproof roll are all reduced compared with Example 1, but the reduction is not as large as that in Comparative Example 1.

[0102] The preparation method of the waterproof roll described in Comparative Example 6 is different from that in Example 1 only in that in the preparation method of the waterproof roll described in Comparative Example 6, the amount of SBS thermoplastic rubber added during the preparation of the surface layer is 20 parts. As a result, the maximum tensile force of the waterproof roll is reduced compared with that in Example 1, and the elastic recovery rate is improved compared with that in Example 1.

[0103] The preparation method of the waterproof roll described in Comparative Example 7 is different from that in Example 1 only in that the surface layer and the elastic layer are swapped in the preparation method of the waterproof roll described in Comparative Example 7, resulting in a waterproof roll that is not flame retardant, but other properties are the same as those in Example 1.

[0104] The preparation method of a waterproof coiled material described in Comparative Example 8 is different from that in Example 1 only in that: the thickness of the waterproof coiled material obtained by the preparation method of the waterproof coiled material described in Comparative Example 8 is 1.2 mm, wherein the thickness of the surface layer is 0.4 mm, the thickness of the elastic layer is 0.4 mm, and the thickness of the self-adhesive layer is 0.4 mm. The difference between Comparative Example 8 and Example 1 is that the thickness of the polymer coiled material becomes smaller, and the thickness of 1.2 mm is basically the same as the thickness of the polymer waterproof coiled material in the existing market, but lower than the thickness of the asphalt waterproof coiled material. The thickness is reduced, resulting in a decrease in the maximum peak tensile force, elastic recovery rate, and coil-to-coil peeling strength of the polymer coiled material, especially the maximum peak tensile force and elastic recovery rate. The thickness not only affects the above-mentioned properties, but also affects the aging resistance and durability of the polymer coiled material, thereby affecting the service life of the polymer waterproof coiled material.

[0105] Although the above embodiments have been shown and described, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
