Abstract
The cross-linked baking putty for latex is made up of vinyl monomer and acrylate monomer as basic components, emulsion through emulsion polymerization and gap-filling cross-linking agent as basic raw materials, and anticorrosion, antimildew, antifreezing agent and filler through mixing. The putty has the characteristics of thick coating, quick drying, no toxicity, no combustion, no explosion and the like, particularly has good water resistance and freezing resistance, and has lower cost than the traditional oily putty. It can be used for various metal baking lacquers, and is especially suitable for the exterior decoration of large and medium-sized cars.
Description
The invention belongs to a kind of metallic paint, be specially the heat cross-linking type latex baking putty of the exterior decoration that is mainly used in big-and-middle-sized car.
Present industrial iron oxide red fat glue putty, amino putty etc. are to add the blending of some filler and auxiliary agent with corresponding resin solution to form, and wherein contain a large amount of organic solvents, not only waste energy, and volatilization enter atmosphere, contaminate environment in construction process.Because solvent, particularly high boiling solvent remain in the system, in the process of baking finish paint, overflow, cause foaming, have a strong impact on decoration quality.Moreover this class putty should not thick being coated with, and coating surpasses 0.5mm, just difficult parching.And in the passenger vehicle production industry of China, because Machining Technology is limit, the vehicle body crust that assembles out is rough and uneven in surface, and particularly the hole concave of weld seam, joint resembles even more serious.The hole that has reaches about 10mm deeply, and smooth for obtaining, slick bodywork surface need repeatedly be coated with Puttying, and repeatedly baking has prolonged construction period greatly, sky surplus a car exterior decoration needs ten.
Nineteen eighty-three, we developed JRG type breast friendship putty, this putty is that the emulsion that basic monomer is produced is made base-material with vinyl acetate between to for plastic and butyl acrylate mainly, the filled putty that is modulated into, though this putty has solved and thickly has been coated with, rapid-curing cutback, pollution and baking bubble problem, but, only be applicable to dry rubbing technology because the immersion swelling does not have fine solution.The present invention takes calking (Interstitially) linking agent and heat cross-linking emulsion to make the putty that base-material is modulated into, also have good water resistance except that being applicable to dry rubbing technology, promptly can be controlled at 2-3%(JRG putty to the water-intake rate of the putty coating that soaked through 24 hours is 25-30%).The anti-immersion of this putty coating, chance water is swelling not, so can also satisfy the requirement of water technique for grinding.Characterize the water resistance of putty in our experiment with water-intake rate, water-intake rate is represented with the suction percentage ratio that toasts the dried putty in back.The measuring method of its water-intake rate is as follows:
With 5 * 10cm tinplate sheet, after sand papering, be weighed as W
1, be coated with the thick putty layer of 2mm and do in 110 ℃ the baking oven baking and take out after 2 hours, put to room temperature and be weighed as W
2, then be placed on to soak after 24 hours in the tap water and take out, wipe with dried cloth and swim, place and be weighed as W in 30 minutes
3, water-intake rate is calculated as follows:
Q = (W
3-W
2)/(W
2-W
1) ×100%
The present invention adopts calking linking agent and heat cross-linking emulsion to make base-material, adds the modulation of Antisepticize and mildew preventive and frostproofer and filler and forms.
Made heat cross-linking emulsion is to be basic monomer with vinyl acetate between to for plastic, methyl methacrylate, ethyl propenoate, butyl acrylate, vinylbenzene, with N-(isobutoxy methyl) acrylamide, N-(methylol) acrylamide, N-(methoxymethyl) acrylamide, vinylformic acid, methacrylic acid do the function monomer.
From above-mentioned two class monomers, each peek is planted, and forms mix monomer according to a certain ratio, in the presence of emulsifying agent, initiator, PH conditioning agent, is dispersion medium with water, makes cross-linked type latex emulsion through semicontinuous emulsion polymerization.
The emulsifying agent of selecting for use has anion surfactants such as nonionogenic tensides such as OP-7, OP-10, peregal, tween and Sodium dodecylbenzene sulfonate, sodium lauryl sulphate, dodecyl sodium naphthalene sulfonate, MS-1.
Annotate: MS-1 is the sulfonated products after OP-10 and the MALEIC ANHYDRIDE condensation, and its molecular formula is:
Manufacturer has: Shijiazhuang Paint Factory, auxiliary reagent factory, Shanghai, Xingtai area auxiliary reagent factory etc.Name of product all claims MS-1.
The initiator of selecting for use has Potassium Persulphate, ammonium persulphate.
The PH conditioning agent has sodium bicarbonate, Sodium phosphate dibasic;
The consisting of of mix monomer (weight %): basic monomer accounts for 80-96%; Function monomer accounts for 20-4%;
The concrete of the kind of basic monomer and function monomer and consumption determined not contain a kind of situation of respectively getting in principle based on following consideration.For respectively getting a kind of situation, if function monomer and basic monomer are selectively respectively to get a kind ofly, also can implement, VAC as 96% and 4% N-MA can implement.If but respectively get a kind of any collocation, then some situation just can not be implemented.N-MA as 96%St and 4% just cannot implement.
About respectively getting 5 kinds extreme case, the scope that can set up should be all belonged to basically, but industrially generally this situation can be do not got, its reason is need not 5 kinds usually can meet the demands, and therefore need not reach 5 kinds, and is all the more so for function monomer especially.
The appearance of above-mentioned situation mainly is because emulsion synthetic prescription is according to desired fundamental property, comes out according to some rule design and test.Whether emulsion has the leading indicator of actual application value, be its minimum film-forming temperature (MFT), and MFT is closely related with the second-order transition temperature (Tg) of superpolymer in the ordinary course of things,
That is:
1/(MFT) ＝ 1/(K) （ (Vp)/(Tgp) + (αVa)/(Tga) )……（1）
K: constant, measuring are 0.92-0.98;
Vp, Va: the bulk factor that is respectively polymkeric substance and film coalescence aid;
α Va: the concentration of expression film coalescence aid in polymer particle;
Tgp, Tga: the second-order transition temperature that is respectively polymkeric substance and film coalescence aid.
For the system that need not add the film forming auxiliary agent, formula (1) becomes:
MFT＝KTg ……（2）
Letex polymerization system for our discussion
1/(Tg) ＝∑ (Wi)/(Tgi) ……（3）
Wi: form each monomeric weight fraction of emulsion formulations, so ∑ Wi=1
Tgi: the second-order transition temperature of forming the homopolymer of each monomer of emulsion formulations
Above-mentioned formula (3) is famous Fox equation.Check in the Tg of some homopolymers from relevant handbook, combined type (3) has designed a series of prescription, has synthesized multiple emulsion by a large amount of experiments, and has successfully modulated the latex baking putty, 2.7 ℃ of the Tg ≈ of present embodiment 1 emulsion; 18.1 ℃ of the Tg ≈ of additional embodiment 1 emulsion; 13.5 ℃ of the Tg ≈ of additional embodiment 2 emulsions.
Experiment shows, second-order transition temperature in 0-25 ℃ of scope the time emulsion (emulsion of this invention is synthetic) can successfully modulate the latex baking putty of this invention.
In addition, to the amount of getting of function monomer, except that the constraint that is subjected to the Fox equation,, certain influence is arranged all to the heat cross-linking degree of emulsion, the viscosity of system, the stability of system.
This specification sheets is foregoing, from above-mentioned two class monomers, mix monomer is formed in each peek kind according to a certain ratio, be not meant on the mathematics in the permutation and combination any several, but come out according to the performance requriements contrived experiment.
The listed monomer of the present invention, designed, and, all can be made qualified emulsion according to the corresponding conditions of the letex polymerization that is provided by Fox equation and superpolymer synthetic chemistry ABC, and then modulation latex baking putty.
Each auxiliary dosage is:
Emulsifying agent accounts for the 1-10% of monomer weight;
Initiator accounts for the 0.1-1.0% of monomer weight;
The PH conditioning agent accounts for the 0.1-2.0% of monomer weight;
