Abstract
The present invention discloses a main material of a spraying film water-proofing material with high tensile strength, which is basically composed of 100 portions of magnesium acrylate monomer water solution and 1 to 20 portions of light magnesium oxide of which the granularity is from 300 to 600. A spraying film layer formed by the main material has high tensile strength; furthermore, the spraying film layer soaked in water with higher alkaline of underground engineering has the advantages of good mechanical property keep and long service life.
Description
Affiliated technical field
The present invention relates to a kind of is the spray film water-proofing material major ingredient and preparation method thereof of major ingredient with vinylformic acid magnesium
Background technology
In the tunnel and other underground works of basic job facilities, very high to the requirement of anti-seep water.For this reason, the spray film water-proofing material of the membrane waterproofing that forms with spray regime that the inventor discloses in the patent No. is the patent of invention of ZL00120645.1 that a kind of underground works uses, this kind water-proof material is made up of major ingredient (basic components), oxygenant, reductive agent three parts.Make three partially mixedly by spray regime, the vinylformic acid magnesium in the major ingredient is pressed the Raolical polymerizable polymerization forming, and forms the ionomer structure by the MAGNESIUM METAL ion in the vinylformic acid magnesium, makes vinylformic acid magnesium form structured material in the moment of spray membrane fussion.But, because the restriction of vinylformic acid magnesium film forming monomer concentration, contain the polymkeric substance that the monomeric spray membrane fussion of vinylformic acid magnesium forms, its tensile strength is lower, can not satisfy the application request of underground works fully, especially when long period of soaking was in the higher water of alkalescence, mechanical properties such as its tensile strength can descend rapidly, and had a strong impact on the work-ing life of vinylformic acid magnesium water-proof material.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of tensile strength high spray film water-proofing material major ingredient, the spray rete tensile strength height that this kind major ingredient forms, and be soaked in the alkaline higher water of underground works, mechanical property keeps, long service life.
The present invention solves its technical problem, and the technical scheme that is adopted is: the spray film water-proofing material major ingredient that a kind of tensile strength is high, it basic composition is: 100 parts vinylformic acid magnesium monomer solution and 1-20 part and granularity are 300-600 purpose light magnesium oxide.
During use, major ingredient of the present invention is sprayed respectively through different equipment or nozzle simultaneously with oxygenant, reductive agent; Or with after a kind of mixing the in major ingredient and oxygenant or the reductive agent, again by different equipment or nozzle with mixed solution and another unmixing composition, ejection mixes simultaneously respectively, moment forms gel and is bonded in processed basal plane and forms rete.
The beneficial effect of technical scheme of the present invention is: owing to contain magnesium and carbonyl group in the magnesium polyacrylate; And being 300-600 purpose light magnesium oxide, granularity has higher activity, magnesium wherein easily and the carbonyl in the magnesium polyacrylate form valence link because of electrostatic attraction, wherein oxygen element also be easy to magnesium polyacrylate in magnesium ion form valence link because of electrostatic attraction, the molecule and the reactive force between the molecule of magnesium polyacrylate are strengthened, the cross-linking set of magnesium polyacrylate increases, relational degree improves, and structure is more firm, and the tensile strength of membrane waterproofing is obviously improved; And in the higher water surrounding of alkalescence, its structure can not be subjected to obvious destruction yet in long period of soaking, and mechanical properties such as tensile strength keep, long service life.Experimental data shows that behind the adding light magnesium oxide, its tensile strength rises to original 2-7 doubly, and elongation at break also satisfies the needs of engineering fully.Concrete experimental data sees the following form:
Spray film water-proofing material of the present invention is except that comprising above-mentioned base stock, can also in propionic acid magnesium monomer solution, add various auxiliary materials and auxiliary agent according to prior art, as filler, defoamer, antibiotic antiseptic, dispersion agent etc., to reduce cost and to improve performances such as its dispersiveness, preservative property, liquid stabilising.
The add-on of above-mentioned light magnesium oxide is 1-8 part.The raising of the add-on of light magnesium oxide and vinylformic acid magnesium spray film water-proofing material tensile strength is proportionate, and considers cost performance, and it is comparatively suitable to add 1-8 part usually.
A kind of method for preparing above-mentioned spray film water-proofing material major ingredient, the steps include: the light magnesium oxide of described proportioning and granularity is added in the vinylformic acid magnesium monomer solution of described proportioning, after mix soaking into, carry out per minute 1500 again and change above high-speed stirring or spheroid mill or colloidal mill in solution till the no visible agglomerating particles.
By high-speed stirring or spheroid mill or colloidal mill, can make light magnesium oxide not produce reunion, be evenly dispersed in the solution and keep its highest activity, fully produce interaction with vinylformic acid magnesium, improve the degree of crosslinking of magnesium polyacrylate, the tensile strength of water-proof material can be improved better.
The invention will be further described below in conjunction with embodiment.
Embodiment
Embodiment one
1 part of adding and granularity are 300 purpose light magnesium oxides in 100 parts vinylformic acid magnesium monomer solution; After mixing infiltration, the high-speed stirring that carrying out per minute 1500 again changes above till the no visible agglomerating particles, promptly obtains this routine spray film water-proofing material major ingredient in solution.
Embodiment two
Composition and the preparation method of present embodiment and embodiment one are basic identical, and different is: the light magnesium oxide of adding is 20 parts, and granularity is 600 orders.The mode that high-speed stirring is replaced with spheroid mill is in solution till the no visible agglomerating particles.
Embodiment three
Present embodiment and embodiment one are basic identical, and different is: the light magnesium oxide of adding is 8 parts, and granularity is 325 orders.The mode that high-speed stirring is replaced with colloidal mill is in solution till the no visible agglomerating particles.
Embodiment four
Present embodiment and embodiment one are basic identical, and different is: the light magnesium oxide of adding is 5 parts, and granularity is 500 orders.Carry out high-speed stirring that per minute 2000 changes again in solution till the no visible agglomerating particles.
Embodiment five
Present embodiment and embodiment one are basic identical, and different is: the light magnesium oxide of adding is 15 parts, and granularity is 450 orders.Carry out high-speed stirring that per minute 2000 changes again in solution till the no visible agglomerating particles.
The present invention is when implementing, certainly also can in propionic acid magnesium monomer solution, add one or more auxiliary material, as filler, defoamer, antibiotic antiseptic, dispersion agent, the component of its interpolation and deal are prior art, with the performances such as dispersiveness, germ resistance and stability of raising material of the present invention, but these components are to objects of the present invention---and promptly improving tensile strength is that main mechanical property does not have substantial influence.
