Polyurethane micro-surfacing seal coat mixture and preparation method and application thereof
The invention provides a polyurethane micro-surfacing seal coat mixture and a preparation method thereof. The polyurethane micro-surfacing seal coat mixture is prepared from the following raw materials in parts by weight: 80-100 parts of an aggregate, 0-20 parts of a filler, 8-15 parts of a polyurethane adhesive and 0.08-0.3 part of a catalyst. The polyurethane micro-surfacing seal coat mixture provided by the invention has good pavement performances and durability. According to the invention, a thin slurry mixture formed by mixing the polyurethane, aggregate, filler and the like according toa designed ratio is paved on a thin layer formed by an original pavement by using mechanical equipment, the concrete has the advantages of favorable durability, high compression resistance, high breaking strength, high strength formation speed, favorable stability, excellent low-temperature crack resistance, excellent fatigue resistance, environment friendliness, energy saving, longer constructiontime and the like, and can be cured at normal temperature.
本发明提供一种聚氨酯微表处封层混合料及其制备方法，采用以下质量配比的原料制成：集料80‑100重量份，填料0‑20重量份，聚氨酯胶黏剂8‑15重量份，催化剂0.08‑0.3重量份。本发明的聚氨酯微表处封层混合料具有良好的路用性能及耐久性。本发明利用机械设备将聚氨酯、集料及填料等按照设计配比拌和成的稀浆混合料摊铺到原路面形成的薄层，具有良好的耐久性，抗压、抗折强度高，可在常温下固化，强度形成快，稳定性良好、低温抗裂性及抗疲劳性能优异，同时其具有绿色环保、节约能源、延长施工时间等优点。
