Coating material for self-adhesive asphalt waterproof coiled material, preparation method for coating material, and temperature-sensing self-adjusting self-adhesive asphalt waterproof coiled material
The invention discloses a coating material for a self-adhesive asphalt waterproof coiled material, a preparation method for the coating material, and a temperature-sensing self-adjusting self-adhesiveasphalt waterproof coiled material. The coating material for the self-adhesive asphalt waterproof coiled material comprises the following components in terms of the total weight of the coating material for the self-adhesive asphalt waterproof coiled material: 20 to 40 wt% of petroleum asphalt No. 90, 15 to 30 wt% of liquid petroleum asphalt, 5 to 10 wt% of an SBR modifier, 1.5 to 5 wt% of an SISmodifier, 2 to 5 wt% of an SBS modifier, 3 to 6 wt% of tackifying resin, 1 to 4 wt% of a composite phase change material and 20 to 30 wt% of a filling material. The composite phase change material disclosed by the invention has the following advantages: through arrangement of a temperature-resistant wrapping layer, the composite phase change material does not leak a phase change core material in the high-temperature production process of an asphalt self-adhesive material and later use and storage of a finished product, and is more stable. In addition, a wrapping material, namely urea-formaldehyde resin has good initial adhesion, and can well improve the stripping performance of the self-adhesive asphalt waterproof coiled material, so the waterproof effect of the self-adhesive asphalt waterproof coiled material is improved, and the service life of the self-adhesive asphalt waterproof coiled material is prolonged.
本发明公开了一种自粘沥青防水卷材用涂盖料及其制备方法和感温自调节自粘沥青防水卷材。以自粘沥青防水卷材用涂盖料的总重量计，该自粘沥青防水卷材用涂盖料包括：90#石油沥青20‑40wt％，液态石油沥青15‑30wt％，SBR改性剂5‑10wt％，SIS改性剂1.5‑5wt％，SBS改性剂2‑5wt％，增粘树脂3‑6wt％，复合相变材料1‑4wt％和填料20‑30wt％。本发明的复合相变材料通过设置耐温包裹层，使得复合相变材料在沥青自粘料高温生产过程中以及成品后期使用、贮存中不会发生相变芯材的泄漏，更加稳定。另外，包裹材料脲醛树脂还兼具了很好的初粘性，对自粘沥青防水卷材的剥离性能具有很好的提高，从而提高了防水卷材的防水效果和使用寿命。
