Abstract

The invention discloses a low temperature resistant modified asphalt waterproof roll material. The prepared modified asphalt waterproof roll material has a higher antibacterial rate and a remarkable antibacterial effect, meanwhile the needle penetration and ductility of the material are high, and the tear resistance performance is better. In addition, the low temperature resistant performance is remarkable. The added tea tree oil endows an excellent antibacterial effect to the target material and meanwhile can promote binding between Longyan kaoline and metakaolin and a substrate tighter, theinterface bonding strength is enhanced, and accordingly the tear resistance performance of the target material is improved. The tea tree oil and carboxymethylcellulose are utilized to conduct modifying treatment on the Longyan kaoline and metakaolin, the components perform a mutual synergistic effect, the flexibility of the target material is improved, the material does not crack at low temperature, the embrittlement phenomenon of the material is improved, and the low temperature resistant performance is improved.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a low-temperature-resistant modified asphalt waterproof coiled material. Background technique [0002] Asphalt waterproofing materials have always been the leading product for building waterproofing, accounting for about 70% of the total market recently, polymer waterproofing materials only accounted for about 10%, and the rest are waterproof coatings and other waterproofing materials. At present, the modified asphalt waterproofing membrane for construction uses polyester fiber non-woven fabric as the base, and SBS (styrene-butadiene-styrene) rubber modified petroleum asphalt rubber as the impregnated covering layer of the base. The plastic film is the anti-adhesive isolation layer of the impregnated covering layer. The modified asphalt waterproof membrane is processed through the processes of material selection, batching, co-melting, impregnation, compos...
