See fig. 1-5.
The embodiment of the invention provides a self-healing and self-adhesive waterproof roll 200 for waterproofing a building.
The self-healing and self-adhesive waterproofing sheet 200 is made of a flexible sheet 100 that can be rolled. Referring to fig. 1, the flexible sheet 100 is formed by combining a first waterproof surface layer 101, an adhesive layer 102 and a second waterproof surface layer 103, wherein the first waterproof surface layer 101 and the second waterproof surface layer 103 are arranged oppositely and are adhered to each other through the adhesive layer 102.
In a modified example of the present invention, the flexible sheet 100 also has fibers therein. The fiber can improve the anti-pulling performance of the waterproof roll material 200 with self-healing and self-adhesion properties and is convenient to lay and use. Especially, when the fiber is used in a large area, the construction is troublesome due to the self weight of the fiber, and the toughness of the fiber can be enhanced due to the arrangement of the fiber. The fibers may be metal fibers, filaments, or plastics, resin fibers, and the like. Preferably, the fibers are embedded in the adhesive layer 102. In addition, the fibers may also be provided and used in the form of a braid.
Further, an insulating layer can be arranged between the first waterproof surface layer 101 and the second waterproof surface layer 103. Alternatively, a plurality of air cushion layers are provided at intervals between the first waterproof surface layer 101 and the second waterproof surface layer 103.
The self-healing and self-adhesive waterproofing roll 200 comprises a main body 201 and a spliced body 202. The main body 201 and the splicing body 202 are integrally formed. In order to obtain better use effect of the waterproof roll material 200 with self-healing and self-adhesion properties, the main body 201 and the splicing body 202 are made of different flexible sheets 100. Wherein the body 201 has a greater stiffness and the splice 202 has a lesser stiffness relative to the body 201. Therefore, the splice 202 can be properly bent and folded to facilitate the matching of other self-healing and self-adhesive waterproofing rolls 200. In addition, the splice 202 is also disposed at the periphery of the main body 201.
The body 201 is substantially a block. For example, the body 201 has no rectangular parallelepiped structure, or a cubic structure, or a long bar shape, or the like. The main body 201 is formed by extending from a first surface 2011 to a second surface 2012, and the first surface 2011 is parallel to the second surface 2012. The main body 201 has a thickness from the first surface 2011 to the second surface 2012, and the thickness can be freely selected, and generally the thickness of the main body 201 is specifically selected according to the application. In addition, by selecting the thickness of the body 201, it is also desirable to select the bending properties thereof.
The splice 202 integrally formed with the main body 201 is configured to be used when a plurality of waterproofing membranes 200 with self-healing and self-adhesion are spliced with each other, so that the two waterproofing membranes 200 with self-healing and self-adhesion in cooperation form a splicing structure without bulge and gap, thereby avoiding the problems of warping and bulge caused by the lapping of the two waterproofing membranes 200 with self-healing and self-adhesion when the existing waterproofing membranes 200 with self-healing and self-adhesion are used.
The joint of the main body 201 and the splicing body 202 forms a splicing seam 2021. The size (e.g., width, depth, diameter, etc.) and shape of the splice 2021 can be freely selected and are not particularly limited. For example, the splice 2021 is a cubic depression, or a rectangular parallelepiped depression, or a stepped groove, or a spherical groove, or the like.
The splice 202 forms a splice 2022 at the end remote from the body 201. In other words, one end of the splicing body 202 is connected with the main body 201, and the other end of the splicing body 202 is far away from the main body 201 and is a free end. Generally, a splice 202 of a self-healing, self-adhering waterproofing roll 200 is used to interact with another splice 202 of a self-healing, self-adhering waterproofing roll 200.
The splicing seam 2021 is matched with the splicing part 2022 in a concave-convex embedded manner, wherein the splicing seam 2021 is a concave part, and the splicing part 2022 is a convex part. When the self-healing and self-adhesive waterproof roll material 200 is used for engineering construction, the two self-healing and self-adhesive waterproof roll materials 200 are matched with each other. For example, two splices 202 of two adjacent and mutually matching self-healing and self-adhesive waterproofing rolls 200 can match the splice 2022 and the splice 2021 in a surface contact manner to form a spliced assembly with surfaces flush with the first surface 2011 and the second surface 2012 respectively. In other words, in the self-healing and self-adhesive waterproofing membrane 200, the main body 201 has a thickness greater than the splice 202, and the combination of the two splices 202 has a thickness similar to that of the main body 201. Thus, when two waterproofing sheets 200 having self-healing and self-adhesive properties are close to and fitted to each other, they are not warped or raised due to mutual overlapping, so that irregular uneven waterproofing surfaces are avoided, and overlapping slits are reduced or even eliminated.
In an alternative example, to reduce splicing, the self-healing, self-adhesive waterproofing membrane 400 includes two splices 2022 (shown in fig. 5) integrally formed with the body 201. Two splices 2022 are formed at both ends of the main body 201, respectively. Thus, one waterproofing membrane 200 having self-healing and self-adhering properties can be mutually matched with two waterproofing membranes 200 having self-healing and self-adhering properties, so that more waterproofing membranes 200 having self-healing and self-adhering properties can be avoided. In addition, the self-healing, self-adhesive waterproofing membrane 200 having two splices 202 can be used as an intermediary member to perform a combined mating connection of two other self-healing, self-adhesive waterproofing membranes 200 having one splice 202.
The splice 202 of the self-healing and self-adhesive waterproofing membrane 200 has the concave-convex arranged splice seam 2021 and splice 2022. Therefore, in different examples, the concave direction of the splicing seam 2021 and the convex direction of the splicing part 2022 can be freely selected, so as to facilitate the splicing amount between the two splicing bodies 202. For example, in some alternative examples, in a self-healing, self-adhesive waterproofing web 200 having two splices 202, the splice seam 2021 of both splices 202 is recessed from the first surface 2011 to the second surface 2012. Alternatively, in other alternative examples, in two splices 202 of the self-healing, self-adhesive waterproofing web 200, the splice 2021 of one splice 202 is recessed from the first surface 2011 to the second surface 2012, and the splice 2021 of the other splice 202 is recessed from the second surface 2012 to the first surface 2011.
In addition, the arrangement mode of the splicing body 202 can also be selected according to the requirement. For example, two splices 202 are spliced by contact of splicing surfaces parallel to the first surface 2011, or two splices 202 are spliced by contact of splicing surfaces inclined with respect to the first surface 2011. In an alternative example, the self-healing, self-adhesive waterproofing membrane 200 includes a cuboid main body 201 and a cuboid splice 202. The main body 201 and the splicing body 202 are the same in shape, and the splicing body 202 is thinner than the main body 201 (as shown in fig. 1). Alternatively, in other alternative examples, the self-healing, self-adhesive waterproofing membrane 300 includes a rectangular parallelepiped body 201 and a splice body 202 of a generally triangular plate structure (see fig. 4).
As an improvement, the splicing surface is provided with anti-slip lines to improve the splicing stability between the two splicing bodies 202. Obviously, when two splices 202 are mated with each other, there is a possibility of slippage in multiple directions, for example, separation in directions away from each other; separation in the extension direction (the direction from the main body 201 to the splice 202 or the opposite direction); in the width direction (e.g., the width direction of the splice 2021).
As an alternative example, the anti-slip pattern is a wave-shaped rib, and the rib may be wedge-shaped. Or the anti-skid grains are a plurality of convex balls arranged at intervals. In a better example, the splice surface has a first region and a second region that are remote from each other. The anti-slip pattern comprises a first anti-slip rib and a second rib, wherein the first anti-slip rib and the second rib are correspondingly arranged in the first area and the second area. The first anti-slip protruding edge is longitudinally arranged, and the second anti-slip protruding edge is transversely arranged. The differently arranged ribs can simultaneously act to prevent slippage of the two splices 202 in different directions. In addition, the bonding layer 102 can also be arranged on the splicing surface of the splicing body 202, so that when the two self-healing and self-adhesive waterproof rolls 200 are matched, the two splicing bodies 202 can be bonded through the bonding layer 102 while being attached to the splicing surface, and the splicing stability and firmness are further improved.
In the present invention, the adhesive layer 102 is made of a raw material of a non-curable waterproof material. The non-cured waterproof material comprises the following components in parts by weight: 40-60 parts of modified asphalt, 8-15 parts of whiskers, 2-6 parts of graphene, 11-15 parts of a softening agent, 11-15 parts of inorganic powder, 0.5-1 part of an elastomer and 2-3 parts of a binder.
Wherein the elastomer comprises one or more of thermoplastic styrene-butadiene rubber, thermoplastic polyurethane rubber, rosin resin, terpene resin and petroleum resin. Or loose PVC resin with the polymerization degree of 1000 is selected as the elastomer. The modified asphalt may be, for example, rubber asphalt (rubberized asphalt). The modified asphalt cementing material can be prepared by processing waste tires into rubber powder, combining the rubber powder according to a certain particle size grading proportion, adding a plurality of high polymer modifiers, and carrying out full swelling reaction with matrix asphalt under the heating condition of full mixing. The modified asphalt has a viscosity of 1.4 to 1.5Pa.S at 160 ℃, an elastic recovery of 80% or more at 25 ℃ and a softening point of 60 ℃ or more. Alternatively, the modified asphalt may also be an asphalt modified with a polyurethane or styrenic thermoplastic elastomer. The crystal whisker can be calcium carbonate crystal whisker, zinc oxide crystal whisker, phosphogypsum crystal whisker and the like. The inorganic powder may be a metal powder, a non-metal powder, or a mixture of a metal powder and a non-metal powder.
