Description

一种冷涂沥青及其制备方法和施工方法 技术领域
本发明涉及一种改性的沥青的制备方法和应用, 具体来说, 特别是涉及一种可常温进行 涂布施工用于 (防滑耐磨)高性能路面铺设的冷涂沥青及其制备方法和施工方法。 背景技术
传统路面材料主要是水泥混凝土或沥青混凝土 (SMA), 沥青混凝土路面材料一般采用 热搅拌热熔沥青和骨料, 使用大型施工设备铺设路面, 传统的路面铺设材料和施工方式存在 很多缺陷, 如面层需比较厚, 施工复杂, 小面积施工修补困难, 质量不稳定, 翻新改造需清 除原路面材料重新铺设, 工程复杂, 工期长, 耗资耗能高污染。
沥青是一种天然的或人工生产的工程材料, 道路铺装用途一般采用石油沥青。在化学上, 沥青是一种具有热塑性的惰性材料,具有非常好的防水抗腐蚀性能, 但是, 初级沥青的物理性 能很差, 强度低, 需加入各种改性剂来提高沥青本身的使用性能。
环氧树脂本身具有优异的力学性能及突出的粘结性、 低收縮率、 良好的耐化学品性, 但 是同时, 环氧树脂较脆, 材料的耐水性, 耐腐蚀性和耐候性能较差, 不能够直接满足用于户 外环境下路面铺设材料或者修补材料的特殊要求, 沥青与环氧树脂相结合能起到取长补短的 功效, 使材料具有优异的综合使用性能。
文献有报道以各种方式和添加物对沥青改性提高其材料性能和强度, 其中包括以环氧树 脂改性的环氧沥青。 如中国专利 200710019324.X, 公开了一种高性能环氧沥青路面材料及其 制备方法和应用。 但此专利中所公开的的环氧沥青常温下为不均相混合物, 不能常温施工也 即不可以冷涂, 需采用与道路沥青相同的施工方式, 经过热搅拌, 热压平铺设路面。
文献报道的另一种相近技术是环氧煤沥青, 为煤沥青与环氧树脂的混合物, 但产品气味 大, 有毒性, 污染, 由于环保问题该材料已逐渐被淘汰。 目前环氧煤沥青产品技术只报道局 限用于防水涂料应用领域, 未见有报道用于路面铺设材料。 发明内容
本发明的目的在于针对现有技术的不足, 提供一种常温下为液态, 性能良好的冷涂沥青 路面铺装材料。
本发明的第一个目的在于提供一种冷涂沥青。 本发明的第二个目的在于提供这种冷涂沥青的制备方法。

A部分所述的反应型树脂为分子结构上含有两个以上环氧反应基团的环氧树脂如双环氧 甘油醚双酚 A环氧树脂、 双酚 F环氧树脂以及酚醛环氧树脂。 反应型树脂可以是单一分子结 构的环氧树脂或加有 AGE/BGE低分子量环氧稀释剂的混合物。 环氧树脂为反应型物质, 当 加入适量固化剂时环氧树脂将起反应, 固化形成具有一定强度的固体。
B部分所述固化剂为常温快固化的胺类固化剂包括脂肪胺、脂环胺、芳香胺及聚胺类等。 适合于本发明的冷涂沥青固化剂除通常为含有一种或多种胺类化合物和其它众所周知的助剂 如促进剂, 催化剂, 稀释剂等多种化合物的混合物。
本发明的第二个目的通过以下技术方案予以实现:
一种冷涂沥青的制备方法, 它是将 1 〜 5重量份 A部分和 1份 B部分在容器中混合并 搅拌均匀即可。
其中 A部分的制备方法为: 将反应釜升温至 100 〜 150°C, 依次加入 10〜30重量份活 性改性剂和 10〜30重量份沥青搅拌直至混合均匀再加入 10〜60重量份反应型树脂, 高速分 散搅拌至混合均匀。在制备 A部分时, 在不改变 A部分组分的物性下可适量加入各种众所周 知的添加剂如消泡剂、 流平剂、 稳定剂和分散剂。
本发明的第三个目的通过以下技术方案予以实现:
上述冷涂沥青作为胶结剂在铺设防滑耐磨路面中的用途。
本发明的第四个目的通过以下技术方案予以实现:
一种利用上述冷涂沥青铺设防滑耐磨路面的施工方法, 冷涂沥青作为防滑耐磨路面铺设 的胶结剂, 将冷涂沥青的 A、 B部分在特定的容器中混合并搅拌均匀, 搅拌的时间为 2 〜 3 分钟, 立即进行摊铺, 摊铺时间为 2〜10分钟, 随后铺撒防滑骨料, 撒满为止, 施工完毕 2 小时后, 扫去表面多余的防滑骨料, 再养护 1 〜 2小时便可通行。
一种利用上述冷涂沥青铺设防滑耐磨路面的施工方法, 冷涂沥青作为防滑耐磨路面铺设 的胶结剂, 将冷涂沥青的 A、 B部分在特定的容器中混合并搅拌均匀, 将骨料混入调配好的 胶里形成砂浆, 砂浆搅拌匀后立即进行摊铺, 用刮刀或其它摊铺工具将砂浆胶摊平即可。
所述骨料为路面铺装常用的级配混料或粒径在 l〜10mm左右的高硬度矿砂、玻璃砂、石 英砂、 石子等。
与现有技术相比, 本发明的有益效果为:
本冷涂沥青选用石油沥青、 反应型树脂、 活性改性剂作为 A部分, 并将 A部分制备成均 相液态混合物, 并按一定配比加入固化剂, 制备出施工时无需热搅拌的冷涂沥青。 作为一种 新的材料, 可取代传统热搅拌沥青用于路面修补、 翻新改造和铺设高强度薄层功能路面, 如 高防滑路面、 耐磨抗油污路面、 排水性路面等。 本冷涂沥青的施工方法采用简单快捷的两步 施工方式, 简化了路面铺设工艺和提高铺设速度及质量。 本冷涂沥青同样适合采用与热搅拌 相似的常温冷搅拌混料一次成型的施工方式。 冷涂沥青的应用包括: (1 ) 新型高性能路面铺 设材料; (2) 新型沥青兼容性胶黏剂用于各种交建材料的粘贴、 植筋、 锚固等; (3 )新型涂 料如防水、 抗腐蚀涂料; (4) 耐磨地坪等。
