Abstract
The invention discloses a kind of graphene repairing concrete crack water-repellent paints, are made of following components and parts by weight：50 58 parts of portland cement, 15 25 parts of glass bead powder, 48 parts of hydrophober, 5 10 parts of acrylic acid rubber powder, 10 15 parts of graphene nanometer sheet, 15 25 parts of quartz sand, glass are chopped 12 parts of silk, 0.05 0.1 parts of defoaming powder, 0.5 1 parts of filler material.The present invention enhances performance relative to existing repairing concrete crack water-repellent paint.
Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of graphene repairing concrete crack water-repellent paint.
Background technology
It is commonplace thing since distress in concrete occurs in building with greatly developing for building decorating industry, it is former
Distress in concrete processing method be：By two-component organic polymer water-repellent paint, allocate, noted with high-pressure grout injector in proportion
Enter crack, infiltrate through rock mass fine cracks, generate polymerisation, form solid and reinforce, filler foaming, still, since it is
Organic material, within a certain period of time can atrophy, therefore can seep water, service life is short, increases maintenance cost.
Later people employ the repairing that coating carries out gap, however, existing frequently-used joint filling repair paint, service life
Short, of high cost, work difficulty is big, its service life is caused to be far smaller than concrete, with two-component high molecular water-proof paint high pressure
After slip casting for a period of time, it is susceptible to atrophy phenomenon.Moreover, common joint filling coating, due to do not focus on ingredient and performance it
Between relationship, often lead to injecting paste material using occurring serious infiltration for a period of time, seriously affected concrete and reinforcing bar
Normal service life has to again repair it among user is helpless.
Later, the applicant was in order to overcome above-mentioned technological deficiency, it is proposed that improvement project is simultaneously applied
201410025392.7 number Chinese invention patent.
Invention content
It keeps on improving, the applicant experiences dearly, and only product, which is constantly brought forth new ideas, preferably to develop.Whether can make
201410025392.7 number the performance of repairing concrete crack water-repellent paint be further enhancedFor this purpose, applicant does
Experiment many times is gone out, has tested many kinds of different components and dosage, paid creative work, just obtained this hair
It is bright.
The purpose of the present invention is to provide a kind of graphite more better than existing repairing concrete crack water-repellent paint performance
Alkene repairing concrete crack water-repellent paint.
Used technical solution is：
A kind of graphene repairing concrete crack water-repellent paint, is made of following components and parts by weight：
Further, portland cement is Portland cement 42.5R.
Further, the quartz sand is 80-120 mesh quartz sands.
Further, the glass glass that silk is 3-5mm length that is chopped is chopped silk.
In the technical solution of the present invention, the effect of portland cement is to improve the speed of condensation, preferably normal silicate
42.5R cement further increases intensity；The quartz sand of the preferred 80-120 mesh of quartz sand is used for further increasing intensity.
For glass bead powder since surface vitreous forms certain granule strength, physicochemical property is sufficiently stable, ageing-resistant weather-proof
Property is strong；As aglite, the compression strength of water-repellent paint can be improved, improves product comprehensive performance.
Hydrophober has good waterproof effect, can allow water-repellent paint mending concrete crack when, make the waterproof of repairing
Coating surface forms thin waterproof glued membrane, prevents the entrance of water.
Acrylic acid rubber powder has strong adhesive force, flexible, cooperates with the effect of good water-proof effect.
Glass is chopped silk, and as reinforcing material, the glass of preferably 3-5mm length is chopped silk, and the stretching that can increase product is strong
Degree and the coefficient of elasticity for improving product.
Graphene nanometer sheet, which has, is more than 35m2The high-specific surface area of/g and flourishing mesoporous, pore structure are reasonably distributed,
It has been found that relative to existing repairing concrete crack water-repellent paint, on the one hand the addition of graphene nanometer sheet can subtract
The use of few acrylic acid rubber powder, makes the dosage of acrylic acid rubber powder be reduced to 5-10 parts；On the other hand product entirety can be improved
Impermeability, test specimen impermeability pressure, adhesion strength and compression strength.
In the content of component, it has been found that the content of graphene nanometer sheet cannot be too low, it is too low waterproof to be applied
Material plays effective effect；Content can not be too high, and too high one comes that cost is very high, and two come it can not also play it to water-repellent paint
100% whole effects.Therefore, it is necessary to a rational effective ranges so that in the range, can give full play to
Synergistic effect brings whole enhancing effect, and can reduce cost as far as possible to formula.Repeatedly grope through applicant, including with
The common adjustment of other components and content, has paid performing creative labour, just obtains the model of graphene nanometer sheet 10-15 parts by weight
It encloses.In such range of each component, integral product is made unexpectedly to be obtained than the content of other ranges stronger impermeable
Aqueous, test specimen impermeability pressure, adhesion strength and compression strength.
It during preparation, need to be only mixed according to said components, until each component is uniformly dissolved, you can product is made, prepares
It is convenient.
The beneficial effects of the present invention are：
By repeatedly to the Adjustment Tests of existing No. 201410025392.7 formulas, having obtained a kind of stronger graphite of performance
Alkene repairing concrete crack water-repellent paint improves impermeability, test specimen impermeability pressure, adhesion strength and the pressure resistance of product entirety
Degree, preferably repair the new and old crack of 10-20mm wide, such as plasterboard, asbestos board, inner-outer wall, roofing and concrete are split
Seam.
