Corrosion-resistant concrete interface treating agent and application thereof
The invention discloses a corrosion-resistant concrete interface treating agent and application thereof. The corrosion-resistant concrete interface treating agent comprises the following components bymass: 60-90 parts of a mineral compound; 0.1-2 parts of PP-g-GMA compatibilized PP/coconut shell powder composite fiber; 5-20 parts of an anionic styrene-acrylic emulsion; and 1-7 parts of a chemicaladditive. The preparation process of the PP-g-GMA compatibilized PP/coconut shell powder composite fiber includes: mixing 90-100 parts of PP, 3-10 parts of GMA and 0.1-1 part of DCP fully and uniformly, and then performing banburying and mixing at 150-250DEG C to obtain PP-g-GMA; subjecting 65-90 parts of PP, 5-15 parts of coconut shell powder and 10-20 parts of PP-g-GMA to blending extrusion and spinning into the PP-g-GMA compatibilized PP/coconut shell powder composite fiber. The invention further provides application of the interface treating agent in preparation of new and old concrete bonding transition layers. When the interface treating agent provided by the invention is applied to preparation of new and old concrete bonding transition layers, a good bonding effect can be achieved, and the corrosion resistance of the transition layers can be guaranteed.
本发明公开了一种抗腐蚀型混凝土界面处理剂及其应用，抗腐蚀型混凝土界面处理剂包含如下质量份数的各组分：矿物复合物60‑90份；PP‑g‑GMA增容PP/椰壳粉复合纤维0.1‑2份；阴离子型苯丙乳液5‑20份；化学外加剂1‑7份；PP‑g‑GMA增容PP/椰壳粉复合纤维制备过程如下：将PP 90‑100份、GMA 3‑10份以及DCP 0.1‑1份充分混合均匀，然后在150～250℃下密炼混合得到PP‑g‑GMA；将PP 65‑90份、椰壳粉5‑15份以及PP‑g‑GMA 10‑20份在150～250℃下共混挤出纺成所述PP‑g‑GMA增容PP/椰壳粉复合纤维；本发明还提供了界面处理剂在制备新老混凝土粘结过渡层中的应用。将本发明提供的界面处理剂应用在制备新老混凝土粘结过渡层时，能够起到很好的粘结作用，而且，能够保证过渡层的抗腐蚀性。
