Description

A kind of clear-water concrete surface treating agent
Technical field
The invention belongs to the field of building materials, and in particular to a kind of clear-water concrete surface treating agent.
Background technique
Concrete is the maximum artificial material of contemporary usage amount, has abundant raw material, cheap, simple production process etc. Feature.Clear-water concrete is the concrete that the decorations such as any external plastering are not made in primary concreting molding, now with people The continuous improvement of environmental consciousness, clear-water concrete technology are more and more applied in engineering.But concrete is substantially one Kind heterogeneous porous material can leave pore, cement and aggregate in weight after extra moisture evaporation in cement hydration process Power effect is lower to generate different sedimentation holes, and hydrated product gel of calcium silicate itself contains gel pore etc..Clear-water concrete because Outside is directly exposed in air without processes, surfaces such as plasterings, and water, carbon dioxide, sulfur dioxide in environment etc. can pass through The hole of concrete surface enters inside concrete, causes erosion damage, seriously affects its service life.
Summary of the invention
The present invention is in view of the above-mentioned problems, provide a kind of clear-water concrete surface treating agent, and realization is to concrete surface layer hair The closure of pore keeps concrete surface construction more closely knit, prevents the entrance of water and other etching mediums.To reach above-mentioned mesh , the present invention uses following technical scheme.
A kind of clear-water concrete surface treating agent, by the material composition of following weight percent:
Wetting dispersing agent: 2%-5%
Bentonite: 3%-5%
Aluminium chloride: 8%-12%
Nanometer calcium carbonate: 2%-3%
Aluminum phosphate: 3%-5%
Hydrochloric acid: 0.5%-1%
White sugar: 0.1%-0.5%
Organic silicon defoamer: 0.001%-0.005%
Water: surplus
The wetting dispersing agent is made of Sodium Polyacrylate and alkyl phenol polyoxyethylene ether nonionic surfactant.
Preferably, the Sodium Polyacrylate relative molecular mass is between 1000-5000.
Preferably, the alkyl phenol polyoxyethylene ether nonionic surfactant is dodecyl phenol polyethenoxy ether.
It is furthermore preferred that Sodium Polyacrylate and ten of the wetting dispersing agent by relative molecular mass between 1000-5000 Dialkyl phenol polyoxyethylene ether is formed according to weight ratio 1-5:1.
Preferably, the bentonite is lithium bentonite.
Preferably, hydrogen chloride mass fraction is 10%-20% in the hydrochloric acid.
Preferably, the organic silicon defoamer is polyether-modified dimethyl silicone polymer.
Wetting dispersing agent in the present invention has extremely low surface tension, can soak concrete substrate, helps other activity The infiltration of substance increases adhesive force；Aluminium chloride can react with the hydrated product of cement, generate the compounds such as calcium chloroaluminate, Concrete density is improved, aluminum hydroxide particles can be generated when furthermore penetrating into inside concrete under alkaline environment, obstruction is mixed Solidifying soil pores；Bentonite can increase system viscosity when surface treating agent stores and form three-dimensional reticular structure tissue particles Object sinks, and makes stable system, increases storage period, when in use, the reticular structure by shearing force effect can depolymerization, make system With good thixotropy and being coated with property, in addition, lithium ion therein can also promote the formation of insoluble crystalline solid, in adequate water Lower bentonite, which may expand, plays certain waterproof action for flakey colloid block pores；Aluminum phosphate, aluminium chloride can also and be received Rice calcium carbonate can capture the Ca of inside concrete2+Three carbon drated calcium aluminates or single carbon drated calcium aluminate are formed, is realized to coagulation The closure of native surface layer pore, keeps concrete surface construction more closely knit, prevents the entrance of water and other etching mediums；Hydrochloric acid can Make system that faintly acid be kept to prevent from generating aluminium hydroxide in storing process；White sugar can postpone surface treating agent and Ca2It is formed The time of new hydrated product, surface treating agent is set preferably to infiltrate through inside concrete, and new hydrated product knot can be made Structure is more complete, improves concrete surface compactness and hardness.
Beneficial effects of the present invention are that product is easy to use, and being painted on faced concrete surface can effective fill concrete Surface layer hole, sealing and curing concrete surface layer prevent the erosion by chemical substance in environment, extend the use of clear-water concrete Service life.
