Problems solved by technology

Although ordinary asphalt waterproofing membrane is low in cost, it has low tensile strength and elongation, poor temperature stability, easy to flow at high temperature, easy to be brittle at low temperature, poor aging resistance, short service life, and needs to be heated during construction, which will generate a large amount of polluting gases, causing serious pollution to the environment
[0004] With the development of technology, modified asphalt waterproofing membranes have appeared. The use of various polymer modified asphalt can greatly improve the performance of asphalt substrates, but its disadvantages are also obvious: its bonding effect is poor, often need to Adhesives are applied on the surface of the base layer and the surface of the coil to bond firmly, which will bring trouble to the construction
Moreover, most of the existing modified bitumen waterproofing membranes have a width of 1 meter. In practical applications, there will be more overlapping seams, and the increase of overlapping seams will bring certain hidden dangers to the waterproof effect.

Abstract

The invention discloses a modified asphalt rubber material and a modified asphalt waterproof coiled material for cold construction; the modified asphalt rubber material comprises 40-50 parts of asphalt, 12-16 parts of SBS (styrene-butadiene-styrene) rubber, 3-5 parts of an affinity agent, 3-5 parts of a tackifier, 5-10 parts of softened oil, 2-5 parts of an antioxidant, and 15-25 parts of a filling agent. The upper surface of the waterproof coiled material is a photocatalytic film layer, and the lower surface is a silicone oil film layer; in construction, the silicone oil film layer is peeled off directly before the waterproof coiled material is pasted to the surface of a base. The modified asphalt ruber material and the modified asphalt waterproof coiled material for cold construction have the advantages that bonding is firm, tear resistance is effective, softness and elasticity are good, resistance to high and low temperature is good, resistance to oxidation and corrosion is good, construction is convenient, and good safety and environmental friendliness are achieved.

Description

Technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to a modified asphalt rubber material and a cold construction waterproof coiled material prepared from the modified asphalt rubber material. Background technique [0002] Waterproof coiled material is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist external rainwater and groundwater leakage. It is used as engineering foundation and construction There is no leakage connection between objects, which is the first barrier to waterproof the entire project and plays a vital role in the entire project. [0003] Currently commonly used waterproofing membranes are bituminous waterproofing membranes, including the base made of polyester felt, glass fiber felt or glass fiber reinforced polyester felt, the asphalt layer dipped on the surface of the base, and the isolation b...
