Problems solved by technology

[0002] The polyethylene waterproofing membranes currently used in the waterproofing market in my country are mostly used in underground, landfill, water conservancy and other projects. Due to the low strength of polyethylene itself, it is easy to crack when it is deformed by the settlement of the base layer, resulting in waterproofing failure.
In order to enhance the strength of polyethylene waterproofing membranes, most polyethylene reinforced waterproofing membranes in the prior art adopt a layered structure composed of fiber cloth and polyethylene. There is a big difference in properties, strain resistance, etc. After compounding, the interlayer structure is extremely unstable. When the interlayer composite force is large, the elongation of the material will rapidly decay. When the composite force is small, it is easy to cause fiber cloth and polyethylene sheet. Laminated lamination, waterproof layer bulges

Abstract

The invention provides a carbon fiber reinforced polyethylene waterproof roll and a preparation method thereof. The preparation method comprises the steps of fully mixing 56-90 parts of linear low density polyethylene (LLDPE) resin, 9-40 parts of chopped carbon fiber, 0.1-0.2 part of an antioxidant and 0.1-0.2 part of white oil, and then granulating; and mixing 95-100 parts of a granulated product, 3-5 parts of carbon black, 0.1-0.2 part of an antioxidant and 0.1-0.2 part of white oil, then plasticizing, extruding, shaping and cooling to obtain the final product. The carbon fiber reinforced polyethylene waterproof roll provided by the invention can overcome adverse effects caused by differences between interlayer structures, and the strength of the carbon fiber reinforced polyethylene waterproof roll is greatly improved.
