Abstract

The invention discloses a waterproof coiled material with excellent low-temperature softness. The waterproof coiled material comprises a basic blank layer and an asphalt self-binding layer, and the waterproof coiled material is characterized in that the asphalt self-binding layer is prepared from the following raw materials in parts by weight: asphalt, naphtha, mineral oil, polyisoprene, hydrogenated styrene-butadiene block copolymer, styrene-butadiene rubber, ethylene propylene diene terpolymer rubber, mullite, an anti-aging agent DNP and ethylene bis-stearmide. The invention also discloses apreparation method of the waterproof coiled material. The waterproof coiled material prepared by adopting a method disclosed by the invention has excellent waterproof performance and also has excellent low-temperature softness. According to the waterproof coiled material disclosed by the invention, through mutual cooperation among the polyisoprene, the mullite and the ethylene propylene diene terpolymer rubber, assisted with ultrasonic microwave combined treatment, the synergistic effect is achieved, the low-temperature softness performance of the waterproof coiled material can be effectivelyimproved, the phenomenon that embrittlement occurs under a lower temperature environment is effectively avoided, and the waterproof coiled material has abroad market prospects.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a waterproof coiled material with excellent low-temperature flexibility and a preparation method thereof. Background technique [0002] Waterproof membrane is a waterproof material product made by impregnating asphalt or polymer waterproof material on the carcass, and is usually provided in the form of membrane. According to the different carcass, waterproof membranes are divided into carcassless membranes, paper tire membranes, glass fiber tire membranes, glass cloth tire membranes and polyethylene tire membranes. Waterproof membranes are mainly suitable for the waterproofing of roofs, basements, indoors, municipal engineering and reservoirs, swimming pools and subway tunnels of industrial and civil buildings. A barrier plays a vital role in the entire project. [0003] With the continuous development of science and technology, more and more buildings appear in some areas wit...
