High temperature-resistant and waterproof coiled material

Abstract

The invention relates to the field of waterproof coiled materials, and discloses a high temperature-resistant and waterproof coiled material. The coiled material comprises a polymer substrate layer, ahot melt adhesive layer, a metal foil layer and a heatproof butyl rubber layer which are sequentially laminated, wherein the butyl rubber layer comprises, by mass, 15-30 parts of a plasticizer, 10-40parts of butyl rubber, 20-50 parts of a high temperature-resistant filler, 30-60 parts of a tackifying resin, 0.5-2 parts of a coupling agent and 0.5-2 parts of an anti-aging agent. The high molecular weight butyl rubber and the high molecular weight plasticizer are combined and reacted with the tackifying resin that is compatible with the butyl rubber to form grid-shaped butyl rubber, so the intermolecular slip rate is reduced; and the combination of the coupling agent and the high temperature-resistant filler makes the surface of the high temperature-resistant filler wrapped with an oily group in order to improve the compatibility of the high temperature-resistant filler and the butyl rubber, so that filler particles are uniformly embedded in the molecular network of the grid-shaped butyl rubber, and the deformation and sliding of the butyl rubber molecular net under the action of a high temperature are reduced, thereby the heatproof property of the heatproof butyl rubber layer is improved.

Description

technical field [0001] The invention relates to the field of waterproof coiled material, in particular to a high temperature resistant waterproof coiled material. Background technique [0002] Waterproof membrane, a roll of waterproof material made of asphalt, rubber or other organic materials, commonly known as linoleum or linoleum. It has good water resistance and good flexibility. The waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass are provided in the form of rolls and are called waterproof rolls. According to the different main components, it can be divided into asphalt waterproof membrane, polymer modified asphalt waterproof membrane and synthetic polymer waterproof membrane; according to the different carcass, it can be divided into carcass-free membrane, paper tire membrane, glass fiber Tire rolls, glass cloth tire rolls and polyethylene tire rolls. Waterproof membranes require good water resistance, stabilit...

AI Technical Summary

Problems solved by technology

Bitumen waterproofing membrane and polymer modified bitumen waterproofing membrane have poor aging resistance, are easy to be brittle and lose waterproofing effect

[0004] However, the adhesive layer of the traditional polymer waterproof membrane has weak adhesion to the roof and poor waterproof performance. Long-term contact with water will affect the bonding effect, resulting in gaps between the glue and the roof. , then it will leak

Moreover, the adhesive layer of the traditional polymer waterproof membrane has poor heat resistance and is not resistant to light and heat. It will deform and flow down the roof when the temperature is above 80°C, resulting in failure of the membrane.
