Embodiment 1

[0047] A plastic sheet with a width of 2.0m is made by extrusion blow molding. The plastic sheet is drawn and uniformly coated on its upper surface with a layer of hot melt pressure-sensitive adhesive with a thickness of 0.35mm and a width of 1.8m. The adhesive layer The surface is sprayed with a layer of acrylic protective coating with a thickness of 0.05mm after drying, and a layer of double-sided silicon-coated isolation film is covered on the top of the coating, and finally after trimming and bending, the two edges are each left with a 10cm non-adhesive layer area. waterproof materials.

Embodiment 2

[0049] A plastic sheet with a width of 2.0m is made by extrusion blow molding. The plastic sheet is drawn and uniformly coated on its upper surface with a layer of hot melt pressure-sensitive adhesive with a thickness of 0.30mm and a width of 1.9m. The surface is sprayed with a layer of acrylic protective coating with a thickness of 0.08mm after drying, and a layer of double-sided silicon-coated isolation film is covered on the top of the coating. Finally, after trimming and bending, the two edges are each left with a 5cm non-adhesive layer area. waterproof materials.

Embodiment 3

[0051] A plastic sheet with a width of 2.0m is made by extrusion blow molding. The plastic sheet is drawn and uniformly coated on its upper surface with a layer of hot melt pressure-sensitive adhesive with a thickness of 0.45mm and a width of 1.6m. The adhesive layer The surface is sprayed with a layer of acrylic protective coating with a thickness of 0.10mm after drying, and a layer of double-sided silicon-coated isolation film is covered on the top of the coating, and finally after trimming and bending, the two edges are each left with a 20cm non-adhesive area. waterproof materials.

[0052] For the products of the above three embodiments, the coiled material is laid on the surface during construction, and the overlapping edges are constructed by hot air double seam welding. After the paving is completed, the surface PET isolation film is removed, and then steel bars are bound on the protective coating surface, and then the concrete is poured.

[0053] After the concrete was cur...

Abstract

The invention discloses a waterproof coiled material having a pre-laid anti-sticking function. A preparation method comprises the steps: with a plastic sheet material as a supporter, a hot melt pressure sensitive adhesive is blade-coated on the plastic sheet material, an acrylic acid isolating protection layer is spayed on the hot melt pressure sensitive adhesive layer, and a PET silicon-coated isolating film is coated on a topside layer. The waterproof coiled material disclosed by the invention has high tensile strength and good tear resistance, is non-toxic and odorless, is wide in adaptive temperature range, can be welded or be in self-adhesive lap joint, forms a full bonding with post-poured concrete, can be directly constructed while walking on the coiled material, and is suitable for waterproof of underground waterproof engineering, such as basements, artificial lakes, culverts, tunnels, subways and the like.

Description

Technical field [0001] The invention relates to a waterproof coiled material used for waterproofing or moisture-proofing and a manufacturing process thereof, and belongs to the field of chemical materials for construction. Background technique [0002] The waterproof board currently used in underground waterproofing projects is separated from the concrete structure after the construction is completed. Once the waterproof board is damaged, water will directly act on the concrete structure and flow between the waterproof board and the concrete structure, so as to find the leakage point in the future. Repairs cause great inconvenience. [0003] In order to solve the problem of water channeling, the field has developed a pre-laid anti-adhesive construction method: the waterproof membrane covered with a self-adhesive film layer is laid on the base surface, and then the structural concrete is poured to make the concrete slurry and the membrane glue The film layers are tightly combined. ...
