Problems solved by technology

[0003] During the service period, thermoplastic elastomer (SBS) modified asphalt waterproofing membrane is prone to aging and cracking under the effects of natural solar radiation, oxidation, temperature change, water erosion, etc., and eventually loses its waterproof effect
At present, the anti-aging effect of modified asphalt waterproofing membranes is mostly achieved by adding organic anti-aging agents, such as phenyl salicylate, ultraviolet absorbers UV-P, UV-0, UV-531, light stabilizers Organic modifiers such as GW-540, sulfur, sulfur-containing organics, and organic peroxides have poor anti-aging effects

Abstract

An anti-aging elastomer-modified asphalt waterproof rolling material sequentially comprises mineral materials, anti-aging elastomer-modified asphalt, a polyester base, anti-aging elastomer-modified asphalt and a PE isolating membrane. Silicate minerals with a lamellar structure is added to the formula of the anti-aging elastomer-modified asphalt waterproof rolling material and has the function of preventing a free radical chain reaction in the aging process of elastomer-modified asphalt by the aid of the good physical shielding function and adsorption capacity of the silicate minerals, so that the anti-aging performance and the thermo-oxidative aging resistance of an elastomer-modified asphalt coating are improved. Besides, SEBS with more stable performance is adopted to replace a traditional thermoplastic elastomer modifier SBS (styrene butadiene styrene), production of free radicals is reduced in the aging process of SBS, and the aging process is slowed down. Accordingly, the anti-aging capacity of the elastomer-modified asphalt coating is remarkably improved.

Description

Technical field [0001] The invention relates to a modified asphalt waterproof coiled material, in particular to an anti-aging elastomer modified asphalt waterproof coiled material. Background technique [0002] Elastomer (SBS) modified bitumen waterproofing membrane is based on polyester felt or glass fiber felt, and styrene-butadiene-styrene (SBS) copolymer thermoplastic elastomer is used as modifier. Both sides are covered with poly Vinyl film, fine sand, powder or mineral particles (sheets) are made of modified bitumen waterproofing membrane, which occupies an absolute leading position in the European waterproof material market. Except Italy, other European countries are mainly modified by SBS , The market share is more than 80%, and it is used in various construction projects such as buildings, highways, railways, bridges, airports and subways. my country has introduced the production technology of modified bitumen waterproofing membranes since the mid-1980s. The elastomer (...
