TECHNICAL FIELD
[0001] The utility model relates to waterproofing membrane technical field, concretely is a high strength anti -sticking type waterproofing membrane. BACKGROUND
[0002] In the house construction, when the foundation is hit, waterproofing membrane is usually laid first, and then the steel bar is tied and the cement is poured. The laid waterproofing membrane is mostly plastic sheet or the pressed composite of plastic sheet and cloth, and the waterproofing membrane is exposed in the environment for a period of time before the steel bar is tied and the concrete is poured, and after being eroded by sunlight and rain, it will gradually age. The weather resistance of the existing waterproof self-adhesive membrane is usually about 30 days, if the construction period is delayed or the plum rain season and other uncontrollable factors are encountered, the waterproofing membrane will be exposed for a long time before the concrete is poured, and will be seriously aged, reducing or losing the waterproofing ability, and then affecting the building quality. Moreover, the waterproofing membrane and the cement paste layer are combined by physical means, and with the passage of time, the bonding strength will decrease, and the waterproofing membrane will be easily dislocated, which needs to be improved. SUMMARY
[0003] To solve the technical problems in the background art, the utility model provides a high strength anti -sticking type waterproofing membrane.
[0004] The utility model technical scheme is as follows:
[0005] A high strength anti -sticking type waterproofing membrane comprises:
[0006] The waterproof layer comprises upper and lower waterproof plates, and a reinforced wire mesh is pressed between the two;
[0007] The lower cloth layer covers the bottom surface of the lower waterproof plate;
[0008] The upper cloth layer covers the top surface of the upper waterproof plate;
[0009] The UV protection layer is covered on the upper cloth layer and is formed by drying the adhesive emulsion;
[0010] The isolation protection layer is adhered to the top surface of the UV protection layer and is used for protecting the UV protection layer.
[0011] Preferably, the lower cloth layer adopts non-woven fabric to provide good buffer protection for the lower waterproof plate and prevent hard objects such as stones in the soil below the waterproofing membrane from damaging or piercing the waterproofing membrane.
[0012] Preferably, the upper cloth layer adopts woven cloth with mesh to improve the physical strength of the top of the upper waterproof plate and improve the physical bonding degree of the waterproofing membrane and the subsequently poured concrete.
[0013] In the application, the reinforcing wire mesh is made of glass fiber or steel wire, and is combined with the two waterproof plates by means of glue (adhesion) or fusion pressing, so as to improve the tensile strength of the coiled material.
[0014] In order to improve the combination degree between the reinforcing wire mesh and the two waterproof plates, the reinforcing wire mesh is provided with a spherical block at the wire mesh connection, and a plurality of grooves are arranged on the surface of the spherical block, so that the glue or the molten part of the two waterproof plates enters the grooves of the spherical block when the two waterproof plates are pressed, thereby improving the anti-separation (peeling) strength of the reinforcing wire mesh and the two waterproof plates.
[0015] As a preferred embodiment of the application, the UV protective layer is made of butyl acrylate emulsion, which is sprayed on the upper cloth layer by spraying and is dried, so as to facilitate storage and transportation. When used, the butyl acrylate emulsion reacts with water in the cement slurry to become liquid and restore viscosity, so as to fully adhere to the cement slurry, thereby improving the combination degree of the coiled material and the cement above it.
[0016] As another preferred embodiment of the application, the UV protective layer is a mixture of butyl acrylate emulsion, compatible agent, glue powder and cement powder, so as to improve the compressive strength and weather resistance of the UV protective layer, thereby prolonging the overall exposed time of the coiled material.
[0017] In the application, the thickness of the upper waterproof plate is greater than that of the lower waterproof plate, so that thicker waterproof material is used to cope with the problem of fast aging of the upper surface of the coiled material.
[0018] Preferably, the thickness of the upper waterproof plate is 1.5-2 times the thickness of the lower waterproof plate.
[0019] In order to improve the compressive strength and tensile strength of the coiled material as a whole, the density of the middle lower layer of the upper waterproof plate is greater than the density of the middle upper layer, and the density of the middle upper layer of the lower waterproof plate is greater than the density of the middle lower layer. The part with greater density is combined with the reinforcing wire mesh to improve the overall strength and service life of the coiled material. At the same time, the part with smaller density has a certain elasticity and is not easy to break, which can improve the compressive strength and puncture resistance of the coiled material and improve the service life.
[0020] The high-strength anti-sticking waterproof coiled material provided by the application improves the overall structural strength of the coiled material through the double cloth layer and the reinforcing wire mesh, improves the service life, improves the sunlight resistance of the coiled material through the UV protective layer, protects the waterproof plate, and improves the overall weather resistance of the coiled material.

[0023] The components represented by the reference numerals in the drawings are:
[0024] 1, upper waterproof board; 2, lower waterproof board; 3, reinforced wire mesh; 31, spherical block; 4, lower cloth layer; 5, upper cloth layer; 6, UV protection layer; 7, isolation protection layer. DETAILED DESCRIPTION
[0025] As Figure 1 shown in the utility model embodiment provides a kind of high-strength anti-sticking type waterproofing membrane, it can be used in building foundation construction, it includes:
[0026] Waterproof layer, including upper and lower waterproof board 1 and lower waterproof board 2, reinforced wire mesh 3 is pressed together between the two;
[0027] Lower cloth layer 4, covering in the bottom surface of lower waterproof board 2;
[0028] Upper cloth layer 5, covering in the top surface of upper waterproof board 1;
[0029] UV (Ultraviolet, ultraviolet) protection layer, covering on upper cloth layer 5, by adhesive emulsion is formed by drying;
[0030] Isolation protection layer 7, adhering in the top surface of UV protection layer 6, for protecting UV protection layer 6.
[0031] Wherein, two waterproof boards are combined together by glue or melting mode, and reinforced wire mesh 3 is clamped, to enhance the tensile capacity of waterproofing membrane.Two waterproof boards adopt high polymer waterproof material, for example, PE, HDPE, LDPE, LLDPE, PVC, EPDM, TPO etc., avoid external water infiltration building foundation.
[0032] Reinforced wire mesh 3 is made of glass fiber or steel wire, and is combined with two waterproof boards by glue or melting pressing mode.Meanwhile, to improve the degree of combination between reinforced wire mesh 3 and two waterproof boards, reinforced wire mesh 3 is provided with spherical block 31 at mesh connection, and the surface of spherical block 31 is provided with a plurality of grooves, when being pressed with two waterproof boards, glue or two waterproof boards melting parts are extruded into the grooves of spherical block 31, to improve the anti-separation strength of reinforced wire mesh 3 and two waterproof boards and between two waterproof boards.Spherical block 31 is made of the same material as mesh.
[0033] Lower cloth layer 4 is adhered on the lower surface of lower waterproof board 2 by glue, and it preferably adopts non-woven fabric, which has flexibility, can play good buffering protection effect to lower waterproof board 2, and its fineness and irregularly arranged silk thread can also prevent hard objects such as stones in soil below the membrane from damaging or puncturing lower waterproof board 2.
[0034] The upper cloth layer 5 is adhered to the upper surface of the upper waterproof board 1 by glue. Unlike the lower cloth layer 4, the upper cloth layer 5 preferably uses a woven cloth with mesh. The woven cloth has higher structural strength, which can improve the physical strength of the top of the upper waterproof board 1 and the physical bonding degree of the coiled material and the upper cement.
[0035] The UV protection layer 6 can be made of butyl acrylate emulsion. The butyl acrylate emulsion is sprayed on the upper cloth layer 5 by spraying to form a protective layer, improve the ultraviolet resistance of the coiled material, and further improve the weather resistance of the coiled material. In order to facilitate storage and transportation, the butyl acrylate emulsion is dried after spraying. When used, the dried butyl acrylate reacts with water in the cement slurry, liquefies to restore viscosity, and fully adheres to the cement slurry. Through the physical and chemical bonding of the upper cloth layer 5 and the UV protection layer 6, the bonding degree of the coiled material and the cement above it is improved.
[0036] In another embodiment, the UV protection layer 6 can also be made of a mixture of butyl acrylate emulsion, compatible agent, glue powder and cement powder. The compatible agent can make the glue powder and cement powder well compatible with the butyl acrylate emulsion, and the glue powder and cement powder can improve the adhesion and light tightness of the UV protection layer 6, thereby improving the compressive strength and ultraviolet resistance of the coiled material, prolonging the overall exposure time of the coiled material, and improving the weather resistance of the coiled material.
[0037] In addition, in this embodiment, the thickness of the upper waterproof board 1 is greater than the thickness of the lower waterproof board 2, so that thicker waterproof material is used to deal with the problem of fast aging of the upper surface of the coiled material, to avoid the rapid spread of the aging part to the reinforcing wire mesh 3, thereby destroying the overall structural bonding of the coiled material and the mechanical strength of the coiled material, and further improving the weather resistance of the coiled material.
[0038] The thickness of the upper waterproof board 1 is preferably 1.5-2 times the thickness of the lower waterproof board 2.
[0039] In addition, in order to improve the overall compressive strength and tensile strength of the coiled material, the upper waterproof board 1 and the lower waterproof board 2 are both non-uniform density sheets. Specifically, the middle lower layer of the upper waterproof board 1 has a greater density than the middle upper layer, and the middle upper layer of the lower waterproof board 2 has a greater density than the middle lower layer. The part with higher density has relatively higher hardness and strength. By combining this part with the reinforcing wire mesh 3, the bonding degree of the two waterproof boards and the reinforcing wire mesh 3 is enhanced, and the overall strength and service life of the coiled material are improved. The part with lower density has certain elasticity and ductility and is not easy to break, which is laid on the outside of the two waterproof boards, which can improve the compressive strength and puncture resistance of the coiled material, and further improve the service life of the coiled material.
[0040] The isolation protective layer 7 is made of PE, PP or the like, and is preferably black to have light absorption.
[0041] The waterproofing material has high strength and is anti-sticking, and the double cloth layer and the reinforced wire mesh 3 improve the overall structural strength of the waterproofing material and prolong the service life of the waterproofing material.
[0042] According to the experiment test of the applicant, the waterproofing material has weather resistance of more than 60 days.
