Abstract

The invention discloses an anti-aging polymer waterproof coiled material convenient for construction and a preparation method thereof. The anti-aging polymer waterproof coiled material comprises a base layer, a polyurethane layer and a polyurea layer, wherein the base layer comprises a polyvinyl chloride soft layer with the thickness of 0.5-0.9 mm, polypropylene fiber non-woven fabric which is compounded on the top surface of the polyvinyl chloride soft layer and has a mesh structure, and polyester fabric which is compounded on the bottom surface of the polyvinyl chloride soft layer and has arough bottom surface; the polyurethane layer is sprayed on the top surface of the polypropylene non-woven fabric; and the polyurea layer is sprayed on the top surface of the polyurethane layer. The polymer coiled material can adapt to the environment that a construction area is damp or sundries such as dust and sand exist or a working face is not a flat face, and has the advantages of being easy and convenient to construct and excellent in weather resistance.

Description

technical field

[0001] The invention relates to a polymer waterproof coiled material for construction engineering and a production method, belonging to the construction engineering category. 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 othe...

Examples

Embodiment 1

[0061] Example 1. An aging-resistant polymer waterproof membrane that is convenient for construction, characterized in that it includes a base layer, a polyurethane layer 4, and a polyurea layer 5;

[0062]The base layer includes a 0.5mm polyvinyl chloride soft layer 2, a polypropylene non-woven fabric with a mesh structure 3 compounded on the top surface of the polyvinyl chloride soft layer 2, and a wool-faced polyester compound on the bottom surface of the polyvinyl chloride soft layer 2. Cloth 1; the polyurethane layer 4 is sprayed on the top surface of the polypropylene non-woven fabric 3; the polyurea layer 5 is sprayed on the top surface of the polyurethane layer 4.

[0063] The polypropylene nonwoven fabric 3 is a polypropylene spunbonded nonwoven fabric.

[0064] Described polypropylene fiber non-woven fabric 3 is 40g / m 2 Polypropylene spunbond nonwoven fabric.

[0065] The polyester cloth 1 is a polyester filament hot-rolled non-woven fabric.

[0066] The polyeste...

Embodiment 2

[0091] Example 2. The difference between this embodiment and embodiment 1 is that the polypropylene non-woven fabric 3 is 40g / m 2 Polypropylene spunbond nonwoven fabric. The thickness of the polyvinyl chloride soft layer 2 is 0.8mm.

[0092] The polyester cloth 1 is a polyester filament hot-rolled non-woven fabric.

[0093] The polyester cloth 1 is polyester filament hot-rolled non-woven fabric with a thickness of 70g / m 2 Polyester filament hot-rolled non-woven fabric.

[0094] 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 ...

Embodiment 3

[0116] Example 3. The difference between this embodiment and embodiment 2 is: as Figure 3-5 As shown, the left side of the bottom surface of the polyvinyl chloride soft layer 2 has a lower lap area 21 that is not provided with a polyester cloth 1, and the right side of the top surface of the base layer has an upper layer that is not provided with a polypropylene non-woven fabric 3. Lap area 22. The spraying auxiliary coil material includes a 0.8mm polyvinyl chloride soft layer 2, a polypropylene non-woven fabric 3 with a mesh structure 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 a polyester cloth 1 with a rough surface.

[0117] Polypropylene non-woven fabric 3 is 50g / m 2 Polypropylene spunbond nonwoven fabric.

[0118] The polyester cloth 1 is a polyester filament hot-rolled non-woven fabric.
