Abstract
The present invention relates to the special correction agent in surface of a kind of undisguised material pervious concrete, belong to chemical industry cleaning supplies technical field. The undisguised material pervious concrete special correction agent in surface of the present invention, is made up of the component of following weight percentage: acid solution 30%-60%, viscosity modifier 15%～35%, stabilizing agent 3%～8%, water 10～30%. The undisguised material pervious concrete special correction agent in surface of the present invention, its cost is low, use safe and convenient, short to the cement mortar checkout time of having solidified of undisguised material pervious concrete remained on surface, has improved concrete permeable effect and apparent effect.
Description
Technical field
The present invention relates to the special correction agent in surface of a kind of undisguised material pervious concrete, belong to chemical industry cleaning supplies technical field.
Background technology
Undisguised material pervious concrete is as a kind of new green environment protection material, because it has the earth's surface " cutaneous respiration " of air-and water-permeableUnique visual sense of beauty of function and top layer people's that exposed stone brings natural simpleness, is applied to landscape garden just more and moreThe road surface of the Condoms such as woods. Undisguised material pervious concrete in work progress, need by the pervious concrete mixing and stirring pave, levelling,Jolt ramming, smear pressure, after being disposed, carry out immediately spraying the covered with plastic film of surface cleaning agent, can make so surperficial coagulationNative and inner concrete generation is poor setting time, and bottom concrete has reached final set state, and superficial water mud does not start to coagulate yetKnot, superficial water mud just can be removed with high pressure water washing like this, and the natural colour shape of top layer stone just reveals.
Due to surface cleaning agent be hand spray have unavoidably thick have thin; Or to affect setting time poor due to many factors such as temperatureGrasp the bad washing time that causes partially late; Or it is tight etc. that corner while covering with plastic sheeting, seam do not cover, and these factors all canCause part surface cement mortar to solidify, punching does not wash clean, and has residual. So not only affected concrete permeable effect but also can affect attractive in appearance.But the good method of also residual cement mortar not being processed at present.
Summary of the invention
The object of this invention is to provide the special correction agent in surface of a kind of undisguised material pervious concrete, its cost is low, use safe and convenient,Short to the residual cement mortar checkout time of having solidified, improve concrete permeable effect and apparent effect.
The undisguised material pervious concrete special correction agent in surface of the present invention, is made up of the component of following weight percentage:
The undisguised material pervious concrete special correction agent in surface preferably being formed by following weight percentage component:
Described acid solution is oxalic acid, dilute sulfuric acid or watery hydrochloric acid.
Described viscosity modifier is xanthans, honey, maltodextrin or acid tackifier (production of Weihai Yun Qing chemical development institute),Preferably xanthans.
Described stabilizing agent is that creaming of emulsion preventing agent EE (production of Xuchang City flying dragon fine chemicals Co., Ltd), beverage are special steady(Guangzhou flies auspicious chemical industry to be had to determine agent JJKW004 (production of Hua Bo bio tech ltd, Hangzhou) or liquid suspension stabilizing agent SF-1Limit company produces).
The present invention is one to undisguised material pervious concrete surface clean technology and effectively supplements, utilizes acid solution saturating to undisguised materialThe alkaline product of water coagulation soil wash cement hydration reaction carries out neutralization reaction removing, simultaneously can be to undisguised material pervious concreteThe concrete condensing in bottom causes corrosion, and the natural colour shape of top layer stone is just revealed. The acid tackify adding in the present inventionAgent, prevents that acid solution rapid osmotic from, to concrete lower floor, extending acid solution in the cement mortar surface reaction time on the one hand, anotherCan prevent that acid solution from use splashing and hurting sb.'s feelings on the one hand, use safe and convenient.
The preparation method of the described undisguised material pervious concrete special correction agent in surface, first takes raw material according to the consumption in formula, soAfter by the raw material after taking with machinery or manually evenly mix, finally bottle for subsequent use.
The using method of the described undisguised material pervious concrete special correction agent in surface, dips undisguised material pervious concrete table with hairbrushFace correction agent, carries out surperficial brushing to the residual cement mortar having solidified, and better by clear water developing result.
The present invention has following beneficial effect:
(1) cost is low, and use amount is few, safe and convenient;
(2) short to the cement mortar checkout time of having solidified of undisguised material pervious concrete remained on surface, improve concrete permeableEffect and apparent effect.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated, but it does not limit enforcement of the present invention.
Embodiment 1
Take oxalic acid 30g, honey 32g, creaming of emulsion preventing agent EE8g, water 30g, then that the raw material after taking is manually equalEven mixing, finally bottles for subsequent use.
Embodiment 2
Take 38wt% dilute sulfuric acid 60g, maltodextrin 15g, beverage stabilizer JJKW0043g, water 22g, then will takeAfter raw material mechanical uniform mix, finally bottle for subsequent use.
Embodiment 3
Take 10wt% watery hydrochloric acid 45g, xanthans 30g, liquid suspension stabilizing agent SF-15g, water 20g, after then takingRaw material artificial evenly mix, finally bottle for subsequent use.
Embodiment 4
Take oxalic acid 55g, acid tackifier 28g, creaming of emulsion preventing agent EE7g, water 10g, then by the raw material after takingMechanical uniform mixes, and finally bottles for subsequent use.
Cleaning experiment:
(1), under normal temperature, the correction agent that embodiment 1-4 is made, dips the special correction in surface of undisguised material pervious concrete with hairbrushAgent, carries out surperficial brushing to the residual cement mortar having solidified. The correction agent that acetonideexample 1,2,4 makes is to residualThe cement mortar clearance solidifying reaches the correction agent that 99.9%, embodiment 3 makes the residual cement mortar clearance having solidified is reached100%, and the stone having solidified is without obscission.
(2) under normal temperature, embodiment 1-4 is made, revise agent, dip the special correction in surface of undisguised material pervious concrete with hairbrushAgent, carries out surperficial brushing to the residual cement mortar having solidified, then rinses with clear water. The correction agent that acetonideexample 1-4 makesThe residual cement mortar clearance having solidified is reached to 100%, better effects if after rinsing with clear water, and the stone having solidified is without coming offPhenomenon.
Claims (3)
