Waterproof macromolecular polyethylene and polypropylene composite roll

Abstract

The invention discloses a waterproof macromolecular polyethylene and polypropylene composite roll. The waterproof macromolecular polyethylene and polypropylene composite roll comprises a lining layer, thermal insulation layers, waterproof layers, fireproof layers, anti-oxidization layers and protection layers, wherein the thermal insulation layers are arranged on upper and lower surfaces of the lining layer; the waterproof layers are arranged on the outer layers of the thermal insulation layers; the fireproof layers are arranged on the outer layers of the waterproof layers; the anti-oxidization layers are arranged on the outer layers of the thermal insulation layers; the protection layers are arranged outside the anti-oxidization layers. The waterproof macromolecular polyethylene and polypropylene composite roll is simple in structure and is widely applied to constructional engineering; the lining layer, the thermal insulation layers, the waterproof layers, the fireproof layers, the anti-oxidization layers and the protection layers are additionally arranged so that the roll has the advantages of good tensile strength, thermal insulation and heat preservation, oxidization resistance, fire resistance and the like; furthermore, the waterproof macromolecular polyethylene layers integrated with a stabilizer are additionally arranged so that the waterproof effect, the weather resistance, the corrosion resistance and the low-temperature flexibility are further improved; the waterproof macromolecular polyethylene and polypropylene composite roll is stable, safe and reliable, and is greatly convenient to use by people.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a polymer polyethylene polypropylene fiber composite waterproof coiled material. Background technique [0002] At present, with the popularization and development of modern building technology and new building material technology, the demand for waterproof materials in the field of construction engineering is increasing, and the quality requirements are also getting higher and higher. a wide space. The traditional waterproof material is mainly composed of petroleum asphalt linoleum, but this type of material is easy to be brittle at low temperature, and it will flow at high temperature, and its tensile strength is low, easy to age, pollutes the environment seriously, and also Projects with long-term water soaking need to consider water resistance and corrosion resistance, which can no longer meet the waterproof and environmental protection requirements of modern buildings.

AI Technical Summary

Problems solved by technology

The traditional waterproof material is mainly composed of petroleum asphalt linoleum, but this type of material is easy to be brittle at low temperature, and it will flow at high temperature, and its tensile strength is low, easy to age, pollutes the environment seriously, and also Projects with long-term water soaking need to consider water resistance and corrosion resistance, which can no longer meet the waterproof and environmental protection requirements of modern buildings

[0003] Waterproof materials play an important role in the construction of roads, bridges, roofs, or buildings that require waterproofing. The quality of waterproof materials directly affects the quality of the entire building. Traditional waterproof membranes such as asphalt felt and SBS have their own toxic properties. , Poor ductility, low tensile strength, poor low-temperature performance, high-temperature softening and other insurmountable shortcomings. The traditional waterproof membrane has poor anti-degeneration performance and large temperature changes, which may easily cause the membrane to break and form small cracks, which will affect the use of waterproof membrane. Longevity and waterproof effect are gradually being eliminated
