Description
Technical field
The present invention relates to a kind of building water-proof paint, particularly a kind of waterproof paint and production method thereof of adding nano material.
Background technology
Waterproof paint is after asphalt waterproofing and mortar waterproof, waterproof paint be at present industry and covil construction in widely used a kind of novel material.Be in the solvent-type waterproofing paint of film forming master material with the synthetic rubber, the tensile strength of filming, anti-fragility etc. all are the important factors that influences coating property.Existing Ethylene Propylene Terpolymer waterproof paint prescription is comparatively single, and its material self performance, bactericidal property, environmental-protecting performance all remain to be improved.
Though the existing water-proof acrylic acid paint that adds nanoparticle is intended to improve coating property, strengthen its sterilization effect, but in the used filler lime carbonate of heavy addition, talcum powder etc. can not be fully and rubber dissolve each other, can only be dispersed in the solvent with rubber, cause the sedimentary problem of coating thus, be difficult for obtaining homogeneous thickness after making the coating conjunctiva, influence the result of use of waterproof paint.And the interpolation kind of nanoparticle is comparatively single in the existing prescription, only doses on a small quantity as auxiliary agent, can't solve the problem of uneven thickness behind the coating conjunctiva.
Summary of the invention
The invention provides a kind of terpolymer EP rubber environment-friendly waterproof paint and production method thereof, solve the technical problem of uneven thickness behind the existing Ethylene Propylene Terpolymer waterproof paint conjunctiva, and improve the performance of waterproof paint.
The technical solution adopted for the present invention to solve the technical problems is:
This terpolymer EP rubber environment-friendly waterproof paint comprises dryness raw material and solvent, and described dryness raw material is as follows with coating total mass part proportioning:

25～35 parts of SBR;
50～70 parts of terpine resins;
50～70 parts of SBS;
3～7 parts of nano zine oxides;
45～65 parts of nano-calcium carbonates;
4～10 parts of nanometer titanium dioxides;
Described solvent is No. 120 solvent oils that account for 430～550 parts of coating total masses.
Described dryness raw material is as follows with coating total mass part proportioning:
100 parts of terpolymer EP rubbers;
30 parts of SBR;
60 parts of terpine resins;
60 parts of SBS;
5.5 parts of nano zine oxides;
55 parts of nano-calcium carbonates;
6.3 parts of nanometer titanium dioxides;
Described solvent is No. 120 solvent oils that account for 490 parts of coating total masses.
Also be added with one or more the mixture in flow agent, dispersion agent, defoamer, thickening material, frostproofer or the sanitas in the described dryness raw material.
The production method of this terpolymer EP rubber environment-friendly waterproof paint, preparation process is as follows:
Step 1 will begin to stir in No. 120 solvent oils addings of the part reactor;
Step 2 adds terpolymer EP rubber, continues to stir to dissolve fully until terpolymer EP rubber;
Step 3 adds SBR in the reactor, and adds No. 120 solvent oils and continue to stir;
Step 4 drops into SBS in the reactor, and adds No. 120 solvent oils of part, stirs until dissolving;
Step 5 drops into nano zine oxide in the reactor, and adds No. 120 solvent oils of part, continues to stir until no particle;
Step 6 adds terpine resin, and adds No. 120 solvent oils of part, stirs until dissolving fully;
Step 7 adds nano-calcium carbonate and nanometer titanium dioxide, and adds No. 120 solvent oils of part, is stirred to nano-calcium carbonate and nanometer titanium dioxide to dissolving fully;
Step 8 is observed dope viscosity, adds No. 120 solvent oils stirrings of residue and gets final product in 30 minutes.
Beneficial effect of the present invention is as follows:
The present invention adopts terpolymer EP rubber, SBR, SBS as elastomeric material waterproof paint exquisiteness, high resilience, antiseptic property are increased.In terpine resin adding and above-mentioned materials, have good consistency and tackify effect, the antiageing effect of strongthener.
The present invention is added with three kinds of nanoparticles, and by scientific matching, filler can be dispersed in the solvent with rubber, has solved the sedimentation problem of coating, and intermixing takes a favorable turn.Waterproof paint of the present invention also has ozone decomposition, sterilization, self-cleaning function, and the various aspects of performance of material all increases simultaneously.
The present invention replaces ordinary calcium carbonate to use as filler with nano-calcium carbonate, compare as the waterproof paint of filler with the interpolation talcum powder, have better result of use: nanometer grade super fine calcium carbonate has space steric effect. in coating, the material that density is bigger in the prescription is suspended, play the anti-settling effect.And can improve performances such as the elongation of rubber, anti-tear disconnected performance, compression set, all than adding general lime carbonate height.Nano-calcium carbonate can be used as loading pigment in coating, have exquisiteness, even, advantages such as whiteness is high, good in optical property.
The nanometer titanium dioxide that adds in the prescription of the present invention can directly utilize sunlight, UV-light, thoroughly decompose the toxic pollutant of organic or inorganic, has the performance of sterilization, environmental protection.
The present invention adds as auxiliary agent with nano zine oxide, and nano zine oxide has the dual nature of nano material and conventional oxidation zinc simultaneously.Compare with the conventional oxidation zinc product, its specific surface area is big, chemically reactive is high, and product fineness, chemical purity and particle shape can be adjusted as required, and has Photochemical effects and cover ultraviolet performance preferably, and its UV-preventing rate is up to 98%; Simultaneously, it also have antibacterial bacteriostatic, a series of special performances such as the anti-enzyme of flavor of dispelling.It is cheap than nanometer titanium dioxide to add nano zine oxide, thereby has saved raw materials cost.
Use No. 120 solvent oils as solvent in the prescription of the present invention, No. 120 solvent oil is industrial heptane again, collects boiling range at 80～120 degree, and major ingredient has normal heptane, isoheptane and suberane, also contains a spot of octane and hexane.The alkane amount of No. 120 solvent oils is low, chemical stability good, and is not perishable, and non-activity sulfide is to the metal non-corrosiveness.The water white transparency of solvent own does not have mechanical impurity and moisture, the cleanliness factor height.Adding No. 120 solvent oils makes coating have nontoxic, dustproof, antifouling, self-cleaning characteristics.
Performance increases behind the compositional refinements of the present invention:
Existing standard is filmed: 14 days tensile strength 2Mpa, elongation at break are 600%, and aging 7 days back draft intensity is 6.8Mpa, and elongation at break is 730%.
Prescription of the present invention: 14 days tensile strength 4.0Mpa, elongation at break 860%, aging 7 days back draft intensity is 7.0Mpa, elongation at break is 1000%, all is higher than standard figures.Solid content brings up to percent 48 by percent 40 in the coating, easily forms thickness during construction.
