Embodiment 1

[0063] Example 1. Such as Figure 1-3As shown, an aging-resistant waterproof structure that is convenient for construction includes a spraying auxiliary layer 4 formed by overlapping and connecting several spraying auxiliary coils 41; Bonding; the top surface of the spraying auxiliary layer 4 is sprayed or coated with a polyurethane layer 5, and the top surface of the polyurethane layer 5 is sprayed with a polyurea protective layer 6; the bottom surface of the spraying auxiliary layer 4 is made of cement-based adhesive or cement slurry The adhesive layer 9 is bonded with the region 8 to be constructed;

[0064] The spraying auxiliary coil 41 includes a 0.5mm polyvinyl chloride soft layer 2, a polypropylene non-woven fabric 1 with a mesh structure that is hot-compressed and laminated on the top surface of the polyvinyl chloride soft layer 2, and hot-pressed and laminated on the polyvinyl chloride soft layer 2. The bottom surface of layer 2 bottom surface is the polyester clot...

Embodiment 2

[0090] Example 2. The difference between this embodiment and embodiment 1 is that the polypropylene non-woven fabric 1 is 40g / m 2 Polypropylene spunbond nonwoven fabric. The thickness of the polyvinyl chloride soft layer 2 is 0.9 mm.

[0091] The polyester cloth 3 is a polyester filament hot-rolled non-woven fabric.

[0092] The polyester cloth 3 is a polyester filament hot-rolled non-woven fabric of 70g / m 2 Polyester filament hot-rolled non-woven fabric.

[0093] The raw material of the polyvinyl chloride soft layer 2 includes the following components and parts by weight: 100 parts of polyvinyl chloride resin, 30 parts of diisononyl phthalate, 2 parts of DOTP softening plasticizer, 2 parts of OPE lubricant, 11 parts of dioctyl oxalate, 2 parts of epoxidized soybean oil, 1.5 parts of antimony trioxide, 0.10 parts of sodium pentachlorophenate, 0.05 parts of pentaerythritol β-dodecylthiopropionate, liquid barium-zinc composite stabilizer 1-2 parts of agent, 5 parts of chlor...

Embodiment 3

[0114] Example 3. The difference between this embodiment and embodiment 2 is: as Figure 4-6 As shown, one side of the bottom surface of the polyvinyl chloride soft layer 2 is left with a lower lap area 21 without polyester cloth 3, and the side of the top surface of the base layer away from the lower lap area is left with a polypropylene non-woven fabric. The upper lap area 22 of the cloth 1. The spraying auxiliary coil material includes a 0.9mm polyvinyl chloride soft layer 2, a polypropylene non-woven fabric with a mesh structure 1 that is hot-pressed and laminated on the top surface of the polyvinyl chloride soft layer 2, and hot-pressed and laminated on the polyvinyl chloride soft layer. 2. The bottom surface of the bottom surface is polyester cloth 3 with a rough surface.

[0115] Polypropylene non-woven fabric 1 is 50g / m 2 Polypropylene spunbond nonwoven fabric.

[0116] The polyester cloth 3 is a polyester filament hot-rolled non-woven fabric.

[0117] The polyest...

Abstract

The invention discloses an anti-aging waterproof structure convenient for construction. The anti-aging waterproof structure comprises a spraying aiding layer formed by connecting a plurality of spraying aiding coiled materials in a lap joint mode, wherein the lap joint areas of every two adjacent spraying aiding coiled materials are bonded through an adhesive; a polyurethane layer is sprayed or smeared on the top surface of the spraying aiding layer, and a polyurea protective layer is sprayed on the top surface of the polyurethane layer; the bottom surface of the spraying aiding layer is bonded with a to-be-constructed area through a bonding layer made of a cement-based bonding agent or cement paste; each spraying aiding coiled material comprises a polyvinyl chloride soft layer with a thickness of 0.5-0.9 mm, a polypropylene non-woven fabric which is compounded on the top surface of the polyvinyl chloride soft layer in a hot-pressing manner and is provided with a mesh structure, and apolyester fabric which is compounded on the bottom surface of the polyvinyl chloride soft layer in a hot-pressing manner and is provided with a rough bottom surface. According to the invention, the problem of poor combination of sprayed polyurea or polyurethane under the condition that a construction area is damp or foreign matters such as dust and sand exist or a working surface is not a flat surface can be solved.

Description

technical field [0001] The invention relates to a waterproof structure for construction engineering, which belongs to the category of construction engineering. Background technique [0002] Waterproof materials are widely used in construction, water conservancy and other projects. At present, my country's waterproof materials are mainly divided into five categories: asphalt coils, polymer sheets, sealing materials, waterproof coatings and special waterproof materials for special purposes. [0003] The waterproofing membrane occupies an important position in building materials, and the quality of the waterproofing membrane directly affects the quality of the entire construction project. Ordinary waterproofing membranes are mainly petroleum, asphalt, paper tires and linoleum, which account for about 70% of the total market in the near future, polymer waterproofing membranes only account for about 10%, and the rest are waterproof coatings and other waterproofing membranes mate...
