Interface agent for steel structure outer wall as well as preparation method and application of interface agent
The invention provides an interface agent for a steel structure outer wall. The interface agent comprises a liquid component A and a powder component B, the liquid component A is pure acrylic emulsion and/or styrene-acrylic emulsion; the solid content of the liquid component A is 20-60%; the powder component B is prepared from the following components in parts by weight: 200 to 700 parts of cement; 200 to 800 parts of sand; 0.3 to 3.0 parts of a water repellent; 0.1 to 2.0 parts of a defoaming agent; 0.2 to 2.5 parts of cellulose ether; the mass ratio of the liquid component A to the powder component B is 1: (2.5-4.5). The adhesion agent can effectively guarantee adhesion with the surface of a steel structure base layer with an anti-corrosion coating, the synergistic strain capacity of the adhesion agent and a steel structure under the stress or temperature change condition is higher, the tensile adhesion strength is higher, and better durability is achieved. The invention further provides a preparation method and application of the interface agent for the steel structure outer wall.
本发明提供了一种钢结构外墙用界面剂，包括液体组分A和粉体组分B；所述液体组分A为纯丙乳液和/或苯丙乳液；所述液体组分A的固含量为20～60％；所述粉体组分B包括以下重量份数的组分：水泥：200～700份；砂：200～800份；憎水剂：0.3～3.0份；消泡剂：0.1～2.0份；纤维素醚：0.2～2.5份；所述液体组分A与粉体组分B的质量比为1:(2.5～4.5)。本发明中的界面剂能有效保证与带防腐涂层的钢结构基层表面的粘结，与钢结构在受力或温变的情况下协同应变能力更强，拉伸粘结强度更高，具有更好的耐久性能。本发明还提供了一种钢结构外墙用界面剂的制备方法和应用。
