Abstract
The present invention provides a concrete curing agent which comprises the following components by taking the total weight of the curing agent as a reference: 10 to 80% of mixed petroleum hydrocarbon, 0.5 to 15% of one or mixture of carboxylate type anionic surfactant, sulphonate type anionic surfactant and polyether class nonionic surfactant, and 10 to 80% of water, wherein the distillation range of the mixed petroleum hydrocarbon is from 350 to 520 DEG C, and the wax content is more than 70%. The curing agent has the advantages of simple formula, small dosage, high water retention rate and good combination property; the curing agent not only can be made into thin emulsion for direct use, but also can be made into concentrated emulsion which is diluted on the spot in use.
Description
The present invention relates to a kind of curing compound, thereby a kind ofly more precisely can form the emulsion type concrete curing agent that film prevents internal moisture evaporation at concrete surface,
Curing compound roughly can be divided into resin type, latex type, silicate-type and emulsion-type.Resin type need be used organic solvent diluting, and aromaticity content must not surpass 8% in the solvent of Japan's regulation curing agent, and volatile constituent should be nontoxic, nonflammable in the U.S. ASTM C-300 regulation curing agent.In fact curing agent with an organic solvent can't reach above-mentioned requirements.The latex type curing agent adopts the emulsion polymerization preparation, and cost is higher.After maintenance was finished, curing film was firm, was difficult to abolish, and subsequent handling is had disadvantageous effect.Silicate-type (aqueous silicate solution is commonly called as water glass) price is low, but water retention is also low, and summer weather can't satisfy the needs on curing concrete road surface when hot.
Kai Fa paraffin wax emulsions type curing agent water retention height in recent years, environmental sound, curing film also removes than being easier to, but the paraffin wax emulsions type curing agent of having developed is a raw material with the high-quality paraffin of high price mostly, and the consumption of emulsifying agent is higher, and compound emulsifying agent and wax amount ratio are substantially about 1: 1, emulsifiers formula is more complicated also, therefore production cost is higher, has limited applying of they, fails to replace in road construction the water glass type curing agent so far.As: CN85105219 has proposed a kind of concrete film curing agent, is made up of materials such as paraffin, stearic acid, aliphatics higher amines, levelling agent and Glacial acetic acid, and wherein the amount ratio of paraffin and emulsifying agent is 1: 1; CN 1047094 has proposed a kind of paraffin emulsifier, is made up of sodium alkyl benzene sulfonate, alkylol amide, tea saponin, cationic surfactant, hydrophilizing agent, anti-hard water agent, solubilizing agent etc., and wherein the amount ratio of paraffin and emulsifying agent is 0.2: 1.
The object of the present invention is to provide a kind of emulsion type concrete curing agent simple, that consumption is few, water retention is high of filling a prescription.
Curing compound provided by the invention comprises following component: with the curing agent gross weight is benchmark,
(1) boiling range is 350～520 ℃, wax content greater than 70% mixing petroleum hydrocarbon, and content is 10～80%;
(2) as the carboxylic acid type of emulsifying agent or a kind of or its mixture in sulfonate type anion surfactant or the polyethers nonionogenic tenside, content is 0.5～15%;
(3) water, content are 10～80%.
Said mixing petroleum hydrocarbon is the intermediates of lubricating oil processing process, i.e. sweat oil or soap wax etc. after decompressed wax oil, the dewaxing, and wax content is greater than 70%, and more preferably greater than 80%, boiling range is 350～520 ℃, preferred 380～450 ℃.Mix petroleum hydrocarbon and account for curing agent gross weight 10～80%, preferred 25～70%.
Said emulsifying agent can be anion surfactant or nonionogenic tenside.Said anion surfactant is selected from carboxylic acid type or sulfonate type anion surfactant, as oleate, stearate, ricinate or alkylbenzene sulfonate etc., can be oleic acid, the salt that stearic acid, ricinolic acid or alkyl benzene sulphonate (ABS) and trolamine, ammonium hydroxide, sodium hydroxide or potassium hydroxide etc. generate.Said nonionogenic tenside is selected from the polyethers nonionogenic tenside, as oleic acid polyoxyethylene, alkylphenol polyoxyethylene and polyacrylic acid polyoxyethylene ether-ester etc.Said emulsifying agent can be above-mentioned a kind of or two or more mixture wherein.The content of emulsifying agent accounts for curing agent gross weight 0.5～1 5%, preferred 2～10%.
The content of said water accounts for curing agent gross weight 10～80%, and preferred 25～70%.When water-content greater than the curing agent gross weight 50% the time, can directly use; For the ease of storing and transportation, also can be mixed with water-content less than 50% concentrated emulsion, being diluted to 50～80% during use at the scene can use.
Curing compound provided by the invention can prepare according to ordinary method, is about to petroleum hydrocarbon, emulsifying agent and water 60～80 ℃ of mixing, stirs to get final product in 10～60 minutes.
Curing compound provided by the invention has the following advantages:
(1) this curing agent replaces the film-forming components of finished product wax as curing agent with mixing petroleum hydrocarbon, replace complicated polycomponent emulsifying agent with 1～2 component emulsifying agent, and the emulsifying agent consumption is few, so production cost reduces greatly.
(2) this curing agent water retention can reach more than 85%, and water glass has only less than 20%.The wear resisting property of curing agent of the present invention, folding strength, ultimate compression strength are all apparently higher than the water glass type curing agent.
(3) the concentrated emulsion good stability of curing agent of the present invention is difficult for layering, adds behind the water just can form uniform dilute emulsion without any need for equipment, and atomize is good, can cover on the road surface equably.
In addition, curing agent of the present invention and water glass or polymer latex or the use of the two mixed together is not only cost-saved, also can further improve water retention.
Further specify the present invention below in conjunction with embodiment.
