Abstract
An organosilicon chemical as road-maintaining agent is prepared from methyl silanol sodium (10-12 wt portions), water-soluble resin (25-35) and water (0-550). The water-soluble resin may be the mixture of polyvinyl alcohol modified resin, polyacrylamide modified resin and water, and may further contain optional organosilicon solution. Its advantages include low cost, high effect, no poison, and no environmental pollution.
Description
The present invention relates to a kind of maintenance of surface agent, particularly a kind of water-preserving curing agent that is used for newly building concrete road surface and other concrete surfaces.
On the surface of new concrete highway pavement, airport pavement and other concrete facilities of building, all need to use curing agent to carry out water conservation and handle.Normal at present employing emulsified olefin is a curing agent, be sprayed at road surface and film forming, but this becomes membrane tissue loose, and poor water retention property influences concrete intensity.Chinese invention patent application CN1237554A discloses a kind of ultra-concentrated cement concrete curing agent and production method thereof; with the butter grease is main raw material; adding soda lye and urea etc. under heated condition makes; add water during use and be deployed into curing fluid capable; though this curing agent is packed after concentrating, transportation cost is lower, is main raw material with the butter grease, the production cost height; alkaline matter has certain corrodibility, is unfavorable for environment protection.
The object of the invention provides that a kind of cost is low, maintenance quality is high, does not influence the road maintenance agent of environment.
For achieving the above object, the technical solution used in the present invention is: a kind of road-maintaining organosilicon agent, it contains (by weight)
10～12 parts of methyl silicon sodium alcoholates
25～35 parts of water soluble resins
0～550 part in water.
In the technique scheme, when making finished product, can add the water of suitable proportion, when the content of water surpasses 550 parts, might cause the instability that finished product is preserved, therefore, the water in the finished product can not surpass 550 parts, in use, can further add dilution.
In the technique scheme, described water soluble resin can be the mixture of polyvinyl alcohol modification resin, polyacrylamide modified resin and water, this mixture has finished product production in the chemical plant, this finished product is 25% to be that the polyvinyl alcohol modification resin, 25% of properties-correcting agent is that the polyacrylamide modified resin of properties-correcting agent and 50% water mix with the methylcellulose gum with the carboxymethyl cellulose.
Further technical scheme can also contain silicon sol, and the content of silicon sol is 5～6 parts.
Principle of work of the present invention is: the high molecular weight water soluble polymer and the organosilicon that utilize modification, form fine and close network structure on the top layer, concrete road surface, and then formation one deck hydrophobic membrane as thin as a wafer, and stop up simultaneously and cut off pore in the concrete, thereby reach " anti-pore " phenomenon, stop the water evaporates of inside concrete, play the effect of water-preserving curing, add silicon sol, can further improve the film-forming properties of curing agent of the present invention.
(contain 500 parts of water with finished product and be example) when the present invention uses, elder generation dilutes with 2 times water, spray in 4～8 hours behind concrete formation, spraying equipment can adopt agricultural atomizer or low-pressure sprayer, and (spray pressure is 0.5～1Mpa), and consumption is 25～30m
2/ kg.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1, curing agent of the present invention is after spraying to the road surface, the film forming densification, and with being combined of concrete road surface, thereby water-preserving curing is effective.
2, the present invention can be miscible with any ratio with water, for convenient transportation, can make concentrated solution earlier, in use thin up again.
3, the present invention is nontoxic, harmless, can or carry by the non-dangerous goods transportation, and is simultaneously free from environmental pollution.
4, cost of the present invention is low, and every square metre of use cost is only about 0.25 yuan.
Below in conjunction with embodiment the present invention is further described:
Embodiment one: 1.1 kilograms of methyl silicon sodium alcoholates, 0.6 kilogram of silicon sol and 3 kg water soluble resin P-P are added in 500 kg water, fully stir and promptly get concrete road curing agent of the present invention, wherein water soluble resin P-P is produced by chemical plant, Danyang, and its major ingredient is 25% to be that the polyvinyl alcohol modification resin, 25% of properties-correcting agent is that the polyacrylamide modified resin of properties-correcting agent and 50% water mix with the methylcellulose gum with the carboxymethyl cellulose.
During use, the water of present embodiment gained road maintenance agent with 2 times is diluted, spray in 4～8 hours behind concrete formation, spray pressure is 0.5～1Mpa, and consumption is 25～30m
2/ kg.
Embodiment two: in the prescription of embodiment one, do not add silicon sol, also can make road maintenance agent, but film-forming properties is slightly a little bit poorer, suitably increase consumption.
