Description

Technical Field

[0001] The invention relates to the technical field of building waterproofing, and more specifically to a method for producing a molded waterproof additional layer. Background Art

[0002] Building waterproofing projects involve many parts of buildings (structures), such as basements, walls, floors, walls, roofs, etc. Its function is to prevent the leakage of rainwater, production and domestic water, and the erosion of groundwater within the designed durability of the building or structure, to ensure that the building structure and internal space are not damaged, and to provide people with a comfortable and safe living space environment.

[0003] Waterproofing roll refers to a flexible waterproofing material that is factory-made, has uniform thickness and can be rolled into a roll. It is one of the important types of building waterproofing materials, accounting for about 80% of the entire building waterproofing materials. At present, it mainly includes three categories: traditional asphalt waterproofing roll, polymer modified asphalt waterproofing roll and synthetic polymer material roll. The latter two types of rolls have superior comprehensive performance and are new waterproofing rolls that are currently being vigorously promoted.

[0004] Relevant specifications require that single-layer or laminated waterproofing membranes must be provided with additional layers at corners, rainwater outlets, pipe roots, etc. to enhance the waterproofing performance. The additional layers are generally made of the same or compatible materials to enhance the performance of the waterproof layer.

[0005] The current method for making an additional waterproof layer for waterproof roll materials is as follows: clean and polish the nodes to make it easier to lay the roll materials there; cut and fold the roll materials to make their shape match the shape of the nodes; lay the cut roll materials to ensure reliable adhesion to form an additional waterproof layer.

[0006] The shortcomings of the current waterproof additional layer approach are: the cleaning and polishing of the nodes are not thorough, leaving hidden dangers for the next steps of folding, cutting and paving; the folding and cutting of the roll material are not precise, and it does not fully match the node shape, leaving hidden dangers for paving; the carcass is disconnected at the cut, the waterproof roll material is discontinuous, and the disconnected parts are filled with adhesives, and the interface becomes a hidden danger of water leakage; the node cleaning and polishing, and the folding and cutting of the roll material are all done manually on site, and the accuracy cannot be guaranteed. Finally, the bonding and paving effect of the waterproof additional layer cannot be guaranteed, leaving a hidden danger of water leakage. Summary of the invention

[0007] In view of the above problems, the purpose of the present invention is to provide a method for producing a molded waterproof additional layer, which can be used to make an additional layer with the same shape and structure as the part to be waterproofed, and directly cover the waterproof part without cutting and folding the roll material and without seams, thereby improving the construction speed and waterproofness of the additional layer.

[0008] The present invention provides a method for producing a molded waterproof additional layer, comprising the following steps:

[0011] S3: Through the extrusion shaping process of the inner mold and the outer mold, the processed material is shaped into an additional layer having the same shape as that of the outer mold.

[0012] In the step S1, the parts include vertical downspouts, horizontal downspouts, pile heads, foundation piers, external wall column heads, and external wall column bases, and the external mold completely covers the parts.

[0013] In step S2, when the coil material is an asphalt waterproof coil material, processing materials are attached to the outer mold, including: using base paper, fiber fabric or fiber felt as a carcass, covering and fixing the carcass on the inner surface of the outer mold; adding heated and melted asphalt into the outer mold and evenly applying it on the carcass, impregnating the carcass with asphalt, and then evenly spreading powdered, granular or flaky anti-sticking material on the surface impregnated with asphalt as a covering layer.

[0014] In step S3, the processed material is shaped into an additional layer having the same shape as that of the outer mold through an extrusion molding process of the inner mold and the outer mold, including: inserting the inner mold into the outer mold, extruding the processed material by the inner mold, and heating the outside of the inner mold and the outer mold to fuse the carcass, the asphalt and the covering layer together.

[0015] In step S2, when the roll material is a polymer modified asphalt waterproof roll material, the processing materials are attached in the outer mold, including: attaching synthetic polymer modified asphalt to the inner surface of the outer mold as a coating layer; attaching fiber fabric or fiber felt to the coating layer as a carcass; and evenly spreading powdered, granular or flaky anti-sticking material on the carcass as a covering layer.

[0016] In step S3, the processed material is shaped into an additional layer having the same shape as that of the outer mold through an extrusion molding process of the inner mold and the outer mold, including: inserting the inner mold into the outer mold, extruding the processed material by the inner mold, and heating the outside of the inner mold and the outer mold to fuse the coating layer, the carcass and the covering layer together.

[0017] In step S2, when the coiled material is a synthetic polymer waterproof coiled material, processing materials are attached to the outer mold, including: using synthetic rubber, synthetic resin, or a mixture of synthetic rubber and synthetic resin as a base material, adding chemical additives and fillers to the base material, and then injecting the mixed material into the outer mold.

[0018] In step S3, the processed material is formed into an additional layer having the same shape as the outer mold through an extrusion molding process of the inner mold and the outer mold, including: inserting the inner mold into the outer mold, extruding the base material by the inner mold, and heating the outside of the inner mold and the outer mold to extrude the base material.

[0019] The base material is shaped in the outer mold by adopting a rolling process.

[0020] The outer mold and the inner mold are both stainless steel molds.

[0039] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] Figure 1 This is a flow chart of a method for producing a molded waterproof additional layer according to Example 1 of the present invention; Figure 2 This is a schematic diagram of the structure of the outer mold according to Example 1 of the present invention;

[0042] like Figure 1 As shown, the production method of the molded waterproof additional layer proposed in this embodiment is used for making a waterproof additional layer with the same structure as the waterproof part of a building for waterproofing of coiled materials, and can also be used for processing other covering layers with shapes.

[0043] The waterproof additional layer is an important part of the building waterproofing project. It is mainly used to enhance the waterproof performance of the building structure and ensure that the building is not affected by water erosion during long-term use. The waterproof additional layer is usually an additional layer of material added on the basis of the main waterproof layer. Its purpose is to improve the durability and reliability of the waterproof layer. According to the specific conditions of the construction, some additional layers can be laid on the upper part of the leveling layer, and then a waterproof layer is attached. Some additional layers are laid on the upper part of the waterproof layer. All of them need to cut the flat waterproof roll material for laying. The roll material is sometimes not tightly attached to the inner and outer corners, resulting in hollowing. The laying seams are inevitable, and there is a risk of leakage. The additional layer produced by the production method of the molded waterproof additional layer is an integrally formed covering layer without seams, which can be laid in one go.

[0044] The production method of the molded waterproof additional layer comprises the following steps:

[0045] S1: A mold is made according to the outer dimensions of the part to be waterproofed. The mold includes an inner mold and an outer mold. A baffle is arranged at the edge of the outer mold. The outer mold is sleeved with the inner mold and matched with the inner mold. The baffle closes the edge gap between the outer mold and the inner mold.

[0046] According to the "General Specification for Waterproofing of Buildings and Municipal Engineering", additional layers should be provided for the waterproofing layer at the flooding places such as gutters, eaves, skylights, rainwater pipes and pipe wells extending out of the roof. At the corners, the intersection of the facade and the plane, the rain (down) water outlet, the root of the pipe, the capital, the foundation pier, the deformation joint, the roof exhaust hole and other places where the whole roll material is not easy to lay, it is necessary to strengthen it with an additional waterproof layer. The waterproof layer can more effectively prevent water from penetrating and improve the safety and durability of the building.

[0047] Various molds are made according to the external dimensions of various waterproof positions on the construction site to produce various styles of additional layers for waterproofing of buildings.

[0048] Since the processing material needs to be shaped, the mold includes an inner mold and an outer mold. The outer mold and the inner mold have the same shape. The inner mold can be inserted into the outer mold. There is a gap between the inner mold and the outer mold to accommodate and extrude the processing material. The extrusion of the inner mold and the outer mold plus hot melting and other processes can shape the raw materials into the shape of the outer mold. The shape and size of the outer mold should be the same as the outer size of the part to be waterproofed. The processed additional layer has the same outer size as the part to be waterproofed, and can just cover the part to be waterproofed for tight waterproofing. The extension length of the edges of the inner mold and the outer mold should be determined according to the requirements of the waterproofing construction. The mold can be used repeatedly.

[0049] In order to prevent the processed material flowing between the outer mold and the inner mold from flowing out of the mold, a baffle with a height of less than 1 cm can be set around the edge of the outer mold. The baffle is perpendicular to the edge of the outer mold and can completely cover and seal the gap between the outer mold and the inner mold to prevent the material from flowing out between the outer mold and the inner mold. The baffle does not affect the sleeve connection between the inner mold and the outer mold.

[0050] The inner mold and the outer mold can be made of stainless steel, which has good thermal conductivity and slight elasticity and can extrude processing materials of different thicknesses.

[0051] S2: According to the waterproof layer roll material of the location, the processing material is attached to the outer mold.

[0052] During construction, the additional layer is generally required to use the same or compatible materials as the waterproof layer. According to the material of the waterproof layer roll to be laid, the corresponding processing material is attached to the outer mold to process the additional layer similar to the waterproof layer roll.

[0053] When the waterproofing layer is made of asphalt waterproofing roll, the processing materials are attached to the outer mold, including: using base paper, fiber fabric or fiber felt as the matrix, covering and fixing the matrix on the inner surface of the outer mold. Adding heated and melted asphalt into the outer mold and evenly applying it on the matrix, the matrix is ​​dipped in asphalt, and then powdered, granular or flaky anti-sticking materials are evenly spread on the surface of the undried asphalt-impregnated matrix as a covering layer.

[0054] There are two types of coils: carcass-free and carcass-supported. Carcass-free coils are rolled products made directly using specific processes and materials. Carcass coils are made by coating other materials on a flat rolled material, with the carcass as a support, to make durable coils with high strength, stability, resistance to external forces, and pressure resistance.

[0055] The carcass can be glued to the inner surface of the outer mold with glue, and the asphalt is spread all over the carcass along the inner surface of the outer mold. The thickness is determined according to the construction situation. The carcass is fully impregnated with asphalt, and then the anti-sticking material is evenly spread on the surface to prevent the adhesion of this surface. The processing materials used are similar to those of asphalt waterproofing membranes.

[0056] The powdery anti-sticking material can be talcum powder or slate powder, the flaky anti-sticking material can be mica scales or vermiculite chips, and the granular anti-sticking material can be ore particles.

[0057] When the waterproofing membrane is a polymer modified asphalt waterproofing membrane, the processing materials are attached to the outer mold, including: attaching synthetic polymer modified asphalt to the inner surface of the outer mold as a coating layer; attaching fiber fabric or fiber felt to the coating layer as a carcass; evenly spreading powdered, granular or flaky anti-sticking materials on the carcass as a covering layer. Film materials can also be added to the carcass as a covering layer.

[0058] Synthetic polymers are long-chain macromolecules formed by connecting many small molecules through chemical reactions. This material has strong plasticity and functionality.

[0059] Synthetic high molecular polymer modified asphalt is an asphalt binder made by adding external additives such as rubber, resin, high molecular polymer, ground rubber powder or other fillers, or taking measures such as mild oxidation processing of asphalt to improve the performance of asphalt or asphalt mixture.

[0060] Apply synthetic high molecular polymer modified asphalt evenly on the inner surface of the outer mold, the thickness is determined according to the construction situation, and the carcass is evenly covered on the synthetic high molecular polymer modified asphalt, and finally the anti-sticking material is evenly spread to prevent the adhesion of this surface. The processing materials used are similar to those of polymer modified asphalt waterproofing membranes.

[0061] When the waterproof layer is made of synthetic polymer waterproofing membrane, the processing material is attached to the outer mold, including: using synthetic rubber, synthetic resin, or a mixture of synthetic rubber and synthetic resin as the base material, adding an appropriate amount of chemical additives and fillers to the base material, mixing them evenly and fully, injecting them into the outer mold, and covering the inner surface of the outer mold. The thickness is determined according to the specific conditions of the construction. The processing material used is similar to the material of the synthetic polymer waterproofing membrane.

[0062] S3: Through the extrusion shaping process of the inner mold and the outer mold, the processed material is shaped into an additional layer with the same shape as the outer mold.

[0063] In order to shape the processed material adhered in the outer mold into an additional layer with a shape, the processed material needs to be pressed, hot-melted and other processes.

[0064] When the processing material is similar to the material of the asphalt waterproofing membrane, the inner mold is inserted into the outer mold, the inner mold extrude the processing material, and the outside of the inner mold and the outer mold are heated to fuse the carcass, asphalt and covering layer together.

[0065] According to the specific production situation, the inner mold can be inserted into the outer mold for multiple times and extrusion can be performed in steps. Extrusion can be performed after the tire body is covered on the outer mold to make the tire body fit in the outer mold. Extrusion can be performed during the asphalt impregnation process to promote uniform asphalt impregnation. Extrusion can be performed after spreading the anti-sticking material to fix the anti-sticking material on the upper surface. During the extrusion process, hot melting is required, and heating can be performed using an electric heater.

[0066] The baffle blocks the edge of the inner mold and the outer mold, forming a closed space between the inner mold and the outer mold to prevent asphalt from flowing out during the hot melting process. The closed space has the same shape and size as the location to be waterproofed, and the additional layer formed by pressing and hot melting has the same shape and size as the location to be waterproofed, is integrally formed, and has an appropriate thickness and good waterproof performance.

[0067] When the processing material is similar to the polymer modified asphalt waterproof membrane, the inner mold is inserted into the outer mold, the inner mold extrude the processing material, and the outside of the inner mold and the outer mold are heated to fuse the coating layer, the carcass and the covering layer together.

[0068] According to the specific production situation, the inner mold can be inserted into the outer mold for multiple times and extrusion can be performed in steps. Extrusion can be performed after the coating layer covers the outer mold to make the synthetic high molecular polymer modified asphalt fit evenly in the outer mold. Extrusion can be performed after the carcass is attached to promote the flat bonding between the carcass and the coating layer. Extrusion can be performed after the anti-sticking material is spread to fix the anti-sticking material on the upper surface. During the extrusion process, hot melting is required, and heating can be performed by an electric heater.

[0069] Hot asphalt bonding, gluing and the like can also be used in combination with the pressing of inner and outer molds to bond the coating layer, carcass and covering layer together.

[0070] When the processing material is similar to the synthetic polymer waterproof membrane, the inner mold is inserted into the outer mold, the inner mold extrude the base material, and the outside of the inner mold and the outer mold are heated to extrude the base material into shape.

[0071] According to the specific production situation, a variety of processes can be used in conjunction with the extrusion of the base material. Rubber processing technologies such as mixing, extrusion or calendering can be used in conjunction with internal and external mold extrusion for processing.

[0072] Internal mixing can be carried out by using an internal mixer, and extrusion or calendering can be carried out by using a rolling roller that extends into an outer mold to roll the base material.

[0073] In this embodiment, the parts to be waterproofed may include horizontal downspouts, vertical downspouts, pile heads, foundation piers, wall outer columns, wall outer column bases, etc. The outer mold completely covers the inner and outer corners of the parts and extends to the wall parts of the inner and outer corners. The width of the additional layer is generally 250mm, and the width of the edge of the outer mold is not less than 250mm. The edge of the processed additional layer can meet the requirements of covering the wall part.

[0074] This embodiment takes a square horizontal drain as an example. A horizontal drain is a drain that is level or approximately level with the ground. Figure 2 As shown, the structure of the outer mold includes a cylindrical plate 1 with the same shape and size as the inner part of the drain. A bottom paving plate 2 is arranged at the front end of the lower side wall of the cylindrical plate 1, and a wall paving plate 3 is arranged at the front end of the cylindrical plate 1. The wall paving plate 3 is vertically connected to the bottom paving plate 2. The area of ​​the wall paving plate 3 and the bottom paving plate 2 and the length of the cylindrical plate 1 should meet the waterproof requirements. Baffles 4 are vertically arranged at the edges of the wall paving plate 3 and the bottom paving plate 2 of the outer mold, and baffles 4 are arranged at the rear end of the cylindrical plate 1. The shape of the inner mold is the same as that of the outer mold. After the inner mold and the outer mold are sleeved, the baffle 4 closes the distance between the inner mold and the outer mold. The additional layer pressed out by the inner mold and the outer mold is just laid on the square-mouthed horizontal drain.

[0075] This mold can be used to process additional layers of multiple square-mouthed horizontal drains, which can be used for paving all square-mouthed horizontal drains in this construction.

[0076] The additional waterproof layer should be attached to the concave and yang corners of the base layer and fully adhered to without any hollowing or twisting.
