Embodiment 1

[0058]Example 1. Such asFigure 1-2 As shown, a flexible polymer waterproofing membrane includes a sprayed layer 4, a base layer, the base layer includes a 0.5mm PVC soft layer 2, and a polypropylene fiber with a mesh structure compounded on the top surface of the polyvinyl chloride soft layer 2 by hot pressing Non-woven fabric 3, thermo-compression compounded on the bottom surface of the PVC soft layer 2, the bottom surface of the polyester fabric 1; the spray layer 4 is sprayed on the top surface of the polypropylene non-woven fabric 3; the raw material of the spray layer 4 is polyurea, thickness Both are 1.0mm.

[0059]The polypropylene non-woven fabric 3 is a polypropylene spunbonded non-woven fabric.

[0060]The polypropylene non-woven fabric 3 is 40g / m2Of polypropylene spunbond non-woven fabric.

[0061]The polyester fabric 1 is a polyester filament hot-rolled non-woven fabric.

[0062]The polyester fabric 1 is a polyester filament hot-rolled non-woven fabric of 70g / m2Of polyester filament...

Embodiment 2

[0085]Example 2. The difference between this embodiment and embodiment 1 is that the polypropylene non-woven fabric 3 is 40g / m2Of polypropylene spunbond non-woven fabric. The thickness of the PVC soft layer 2 is 0.8 mm. The raw material of the spray coating 4 is polyurethane, and the thickness is 1.0 mm.

[0086]The polyester fabric 1 is a polyester filament hot-rolled non-woven fabric.

[0087]The polyester fabric 1 is a polyester filament hot-rolled non-woven fabric of 70g / m2Of polyester filament hot-rolled non-woven fabric.

[0088]The raw materials of the PVC soft layer 2 include the following components and contents 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 β-dodecyl thiopropionate pentaerythritol ester, liquid barium zinc compound s...

Embodiment 3

[0110]Example 3. The difference between this embodiment and embodiment 2 lies in:Figure 3-5As shown, the left side of the bottom surface of the PVC soft layer 2 is left with a lower lap area 21 without polyester fabric 1, and the right side of the top surface of the base layer is left with an upper side without polypropylene non-woven fabric 3. Overlap area 22. The spraying auxiliary coil includes a 0.8mm polyvinyl chloride soft layer 2, a polypropylene non-woven fabric with a mesh structure laminated on the top surface of the polyvinyl chloride soft layer 2 by hot pressing, and a polyvinyl chloride soft layer by hot pressing. 2 The bottom of the bottom surface is polyester cloth 1 with a wool surface.

[0111]Polypropylene non-woven fabric 3 is 50g / m2Of polypropylene spunbond non-woven fabric.

[0112]The polyester fabric 1 is a polyester filament hot-rolled non-woven fabric.

[0113]The polyester fabric 1 is polyester filament hot-rolled non-woven fabric, 90g / m2Of polyester filament hot-ro...

Abstract

The invention discloses a flexible polymer waterproof coiled material and a preparation method thereof. The flexible polymer waterproof coiled material comprises a spraying layer and a base layer; thebase 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 layerin a hot-pressing mode and has a mesh structure, and polyester fabric which is compounded on the bottom surface of the polyvinyl chloride soft layer in a hot-pressing mode and has a matte bottom surface; the spraying layer is sprayed on the top surface of the polypropylene fiber non-woven fabric; and the spraying layer is made of polyurethane or polyurea. The polymer coiled material can adapt tothe 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 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 the building materials products, and the quality of the waterproofing membrane directly affects the quality of the entire construction project. Ordinary composite waterproofing membranes are mainly petroleum, asphalt, paper tires and linoleum, which recently accounted for about 70% of the total market, polymer composite waterproofing membranes only accounted for about 10%, and other waterproof coatings and ...
