一种水工防护聚脲材料的混凝土底涂
摘要：
本发明公开了一种水工防护聚脲材料的混凝土底涂。它包括A组分材料和B组分材料，所述A组分材料由异氰酸酯、多元醇、偶联剂、溶剂组成；所述B组分材料由扩链剂、抗氧剂、溶剂组成；所述A组分材料由按重量份数计为70‑134份异氰酸酯、80‑150份多元醇、2‑20份偶联剂、50‑150份溶剂组成；所述B组分材料由按重量份数计为25‑75份扩链剂、1‑5份抗氧剂、50‑140份溶剂组成。克服了现有底涂在长期浸水或高湿状态下附着力大幅度降低或丧失，聚脲材料鼓泡、脱落的缺点；具有使用方便、性能优越的优点。
摘要（英）：

The invention discloses a concrete bottom coating of a concrete work protection polyurea material. The concrete bottom coating comprises an A ingredient material and a B ingredient material, wherein the A ingredient material is prepared from 70 to 134 parts of isocyanate, 80 to 150 parts of polylol, 2 to 20 parts of coupling agents and 50 to 150 parts of solvents through being metered in parts by weight; the B ingredient material is prepared from 25 to 75 parts of chain expanding agents, 1 to 5 parts of antioxidants and 50 to 140 parts of solvents through being metered in parts by weight. The defects that the attachment force of the existing bottom coating is greatly reduced or lost in the long-time water soaking or high-humidity state, and a polyurea material bulges and falls off are overcome. The concrete bottom coating has the advantages that the use is convenient; the performance is excellent.
