Modified emulsified asphalt and preparation method thereof
The invention discloses modified emulsified asphalt and a preparation method thereof. The modified emulsified asphalt is prepared from the following components in parts by weight: 100 parts of modified asphalt, 1.0 to 8.0 parts of an emulsifier, 0.2 to 1.0 part of a stabilizer and 30 to 100 parts of water, the modified asphalt comprises the following components in parts by weight: 100 parts of cationized matrix asphalt, 0.5-5 parts of a high-molecular polymer, 1-10 parts of a plasticizer and 0.1-0.5 part of a cross-linking agent, the cationized matrix asphalt is obtained by carrying out chemical grafting reaction on a modifier and matrix asphalt. The problems that high-molecular polymer modified asphalt is difficult to emulsify and unstable to store are solved.
本发明公开了一种改性乳化沥青及其制备方法。本发明改性乳化沥青，按重量份数计，包括以下组分：改性沥青100份，乳化剂1.0～8.0份，稳定剂0.2～1.0份，水30～100份；所述改性沥青，按重量份数计，包括以下组分：阳离子化基质沥青100份，高分子聚合物0.5～5份，增塑剂1～10份，交联剂0.1～0.5份；所述阳离子化基质沥青是由改性剂与基质沥青进行化学接枝反应得到。本发明解决了高分子聚合物改性沥青难以乳化和储存不稳定的问题。
