Environment-friendly waterproof coiled material and preparation method thereof
The invention discloses an environment-friendly waterproof coiled material and a preparation method thereof. The waterproof coiled material comprises the following raw materials in parts by weight: 40-50 parts of matrix asphalt, 10-13 parts of base oil, 10-15 parts of rubber powder and 8-15 parts of a reinforcing agent, According to the invention, the reinforcing agent contains a large number of hindered phenol structures, sulfur atoms and oxyacid of phosphorus, hindered phenol can prevent oxidation when the waterproof coiled material is oxidized while the sulfur atoms are oxidized into sulfoxide and sulfone compounds, and the sulfoxide and sulfone compounds can further improve the aging resistance of the waterproof coiled material; during combustion, the oxyacid of phosphoruscatalyzes a hydroxyl-containing compound to be dehydrated into carbon, then a coke layer is generated on the surface of the material, and the coke layer can isolate oxygen and insulate heat to extinguish flames, so that the waterproof coiled material has a good flame retardant effect; and other anti-aging agents and flame retardants do not need to be added when the waterproof coiled material is prepared, so that the manufacturing cost is greatly reduced.
本发明公开了一种环保型防水卷材及其制备方法，该防水卷材包括如下重量份原料：40‑50份基质沥青、10‑13份基础油、10‑15份橡胶粉、8‑15份增强剂；该增强剂上含有大量受阻酚结构、硫原子、磷的含氧酸，在防水卷材受到氧化时受阻酚会阻止氧化，同时硫原子被氧化成亚砜和砜类化合物，亚砜和砜类化合物能够进一步提升防水卷材的耐老化能力，在燃烧时，磷的含氧酸在催化含羟基化合物脱水成碳，进而在材料的表面产生焦炭层，焦炭层能够隔氧、隔热进而使得火焰熄灭，使得防水卷材具有很好的阻燃效果，且制备防水卷材时不需要加入其它防老剂和阻燃剂，大大降低了制造成本。
