Abstract
The invention relates to an interface treating agent prepared by slag micro-powder, belonging to technical fields of comprehensive utilization of solid waste materials and chemical building materials. The proportions of the raw materials of the interface treating agent are as follows: 15-35% of slag micro-powder, 25-45% of cement, 30-50% of sand, 2-5% of dispersible polymer powder, and 0.2-0.5% of water-retaining agent. According to the proportions, the raw materials are proportioned and put in a mixer in sequence, and after complete mixing, the interface treating agent can be obtained. As the interface treating agent is added with extremely fine slag micro-powder, particle composition is more reasonable, the activity index is better, the surface strength of the foundation layer of a wall body is improved, and the adhesive force of a rendering coat is ensured.
Description
Technical field
The present invention relates to a kind of concrete interface treating agent, belong to solid waste comprehensive utilization and chemical building material technical field with the slag micro powder preparation.
Background technology
The buildings in general surfaces externally and internally all will be smeared the sand finish layer, and buildings and body of wall are played a protective role, and improves the weather resistance of buildings, and it is closely knit, smooth and attractive in appearance to reach body of wall again.This just requires sand finish layer and body of wall basic unit that effective adhesive can be arranged.For slick concrete wall after the demoulding and various porous, bodies of wall such as light cinder brick that water-intake rate is high,, must carry out interface processing to it because the surface adhesion force and the cohesive force of they and plastering mortar are poor.
Interface treating agent is a kind of interface strongthener, is used to strengthen the adhesive property between body of wall basic unit and the plastering mortar, and it carries out surface treatment to body of wall basic unit, makes and forms the transition key coat between basic unit's body of wall and the float coat.The coating of interface treating agent both had very strong cohesive force with original surface of wall, was easy to thereon the further new material of bonding again, thereby formed a transition layer with two-way bonds well performance.Can prevent effectively that body of wall basic unit and float coat from forming hollowing, avoid because the float coat that imperfect bonding caused flakes and comes off.
Summary of the invention
The purpose of this invention is to provide a kind of interface treating agent that utilizes the slag micro powder preparation.This interface treating agent carries out surface treatment to body of wall basic unit, can effectively prevent body of wall basic unit and float coat because the float coat that imperfect bonding caused flakes and comes off.
A kind of interface treating agent of the present invention, the composition and the weight percent of this interface treating agent are as follows:
Slag micro powder 15-35% cement 25-45%
Sand 30-50% latex powder 2-5%
Water-holding agent 0.2-0.5%
Described slag micro powder is converter or electric furnace slag, grinding after iron removal by magnetic separation is handled, its specific surface area 〉=600m
2/ kg accounts for 90% of total mass, the content of metallic iron≤0.5% less than the slag micro powder of 30 μ m particle diameters.
Described cement is 42.5 grades or 52.5 grades of ordinary Portland cements.
Described sand, particle diameter are 0.05-0.5mm.
Described latex powder is any one or two kinds of in styrene-propene yogurt rubber powder, acrylate latex powder, the vinyl acetate-ethylene latex powder.
Described water-holding agent is any one or two kinds of in Natvosol, hydroxyethylmethyl-cellulose, the Vltra tears.
According to the said ratio batching, put into mixing machine successively, even through thorough mixing, promptly get interface treating agent.
The interface treating agent of this preparation belongs to powdery, adds suitable quantity of water during use, stirs and can use.Be mainly used in the processing on concrete, gas concrete, surfaces such as light cinder brick that water-intake rate is high, solve that these body of wall substrate surface water-intake rates are big, porous or the smooth surface that causes be difficult for bonding, thereby cause the float coat hollowing, quality problems such as ftracture, peel off.
Utilize the interface treating agent of slag micro powder preparation, because the slag that adds is superfine, specific surface area 〉=600m
2/ kg more becomes rationally the grain composition of this interface treating agent, and can make the activity index of gelling material better.Improve substrate surface intensity, guarantee the cohesive force of mortar, play the bridging effect that bonds preferably between body of wall basic unit and plastering mortar, wall mortar and body of wall basic unit are combined into a firm integral body in the assurance.Also can seal the hole of body of wall basic unit, reduce the water-absorbent of metope, guarantee that plastering mortar hardens under optimal conditions.
