Description

Technical Field

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

[0002] As an important building waterproof material, waterproof membrane is widely used in waterproof treatment of building parts such as roofs and basements. Traditional waterproof membranes are usually made of asphalt, polymer materials or their composite materials, and are prepared through specific processes to meet the waterproofing needs in different environments.

[0003] Although existing waterproofing membranes can meet waterproofing needs to a certain extent, the following problems still exist: Traditional membranes are prone to cracks at the joints due to the physical properties of the materials. This is because the bonding strength between the membranes is insufficient or the materials shrink due to changes in ambient temperature, which causes water leakage. Under extreme temperatures, existing materials may not be able to maintain good adhesion and stability, resulting in damage to the waterproof layer. The construction process of existing waterproofing membranes may be cumbersome, requiring multiple processes and a long construction time, which not only increases construction costs, but also prolongs the project cycle. Some waterproofing membranes may release harmful substances during the production and construction process, which is not conducive to environmental protection and human health. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a waterproof coiled material base and a waterproof coiled material and a preparation method thereof, wherein the waterproof coiled material has excellent temperature resistance, lasting adhesion and waterproof performance.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] A waterproof coiled material crude oil comprises the following raw materials in parts by weight: 31-42 parts of asphalt, 1-5 parts of styrene-butadiene-styrene block copolymer, 11-15 parts of asphalt base oil, 1-5 parts of solid particulate matter, 8-15 parts of rubber powder, 22-28 parts of ash and 0-17 parts of stone powder.

[0007] Preferably, the asphalt base oil is cycloalkane oil.

[0008] The solid particulate material is polypropylene.

[0009] The rubber powder includes one or more of tire recycled rubber powder, asphalt modified rubber powder and recycled rubber powder.

[0010] The ash is fly ash.

[0011] The stone powder includes one or both of heavy calcium powder and talcum powder.

[0012] The present invention also provides a waterproof coiled material, comprising an upper polyethylene film layer, a lower polyethylene film layer and the waterproof coiled material base, wherein the upper polyethylene film layer is bonded to the lower polyethylene film layer through the waterproof coiled material base.

[0013] The present invention also provides a method for preparing a waterproof coiled material, comprising the following steps:

[0014] S1. Weigh asphalt and asphalt base oil by weight, mix and stir the two, add solid particulate matter and styrene-butadiene-styrene block copolymer, heat to a certain temperature, and keep dissolving at this temperature for 2 hours to obtain a mixture A;

[0015] S2, adding part of the rubber powder to the mixture A, heating it to a certain temperature, and maintaining the dissolution and modification at this temperature for 1 hour, then adding the remaining rubber powder, and continuing the dissolution and modification for 1.5 hours to obtain a mixture B;

[0016] S3, grinding the mixture B, pouring it back after grinding, adding ash and stone powder in batches, stirring them fully, and obtaining a waterproof coiled material crude oil;

[0017] S4, cooling the crude oil obtained in step S3 to a certain temperature, placing it on the surface of the lower polyethylene film layer, spreading the upper polyethylene film layer flatly to cover the upper layer of the crude oil, rolling it into shape, and passing the formed material through a cooling facility, cooling it to room temperature, and then rolling it up to obtain a waterproof roll material.

[0018] Preferably, after adding the solid particulate matter and the styrene-butadiene-styrene block copolymer in step S1, the temperature is raised to 190-200°C.

[0019] Preferably, in step S2, after adding part of the rubber powder to the mixture A, the temperature is raised to 210-220°C.

[0020] Preferably, in step S3, ash and stone powder are added in batches at a temperature of 190-210° C. and stirred for more than 60 minutes to obtain the waterproof coiled material crude oil.

[0021] Preferably, in step S4, the crude oil is cooled to 100-120° C. and placed on the surface of the lower polyethylene film layer, and the upper polyethylene film layer is spread flat to cover the upper layer of the crude oil and rolled to form.

[0022] Compared with the prior art, the present invention has the following advantages and technical effects:

[0023] The waterproofing membrane provided by the present invention has excellent elongation, can adapt to slight changes in the building structure and thermal expansion and contraction, and can effectively prevent the material from breaking. Compared with traditional waterproofing membranes, the waterproofing membrane provided by the present invention is not easy to produce cracks at the joints, and has excellent tensile resistance, including weather resistance and stickiness under extreme high and low temperature conditions. The waterproofing membrane can maintain good physical properties in high and low temperature environments, ensuring stability and durability under different climatic conditions. Even after long-term use, its bonding performance can still be maintained, ensuring firm bonding with the base layer, and preventing damage to the waterproof layer due to bonding failure. At the same time, due to the improvement of its tensile resistance, the risk of water leakage is significantly reduced, the reliability of the waterproof layer is improved, and it is suitable for waterproofing treatment of parts such as roofs and basements. The waterproofing membrane of the present invention provides a new type of material with superior performance, safety and reliability in the field of building waterproofing, effectively solving the defects in the prior art, and has broad application prospects and significant economic benefits.
