Background technology
Within 2012, Chinese coating industry total output reaches 1271.875 ten thousand tons, continues the ground of the global coating largest production of maintenance statePosition. Due to the coating performance of solvent based coating excellence, at present, China's solvent based coating still accounts for coating total output more than 52%, wideGeneral being used as: industrial machinery coating, car paint, space flight and aviation coating, marine paint, highway bridge coating, anticorrosive paint, buildingIn the high-end application such as coating.
Solvent based coating, in production and coating process, approximately has the organic solvent of 3,500,000 tons to wave after coating uses every yearSend in atmosphere, both caused atmosphere pollution, waste again ample resources. Show according to China's Industry Information Network data: 2012, ChinaDimethylbenzene accumulative total import volume reaches 7,010,000 tons, increases by 24.7% on a year-on-year basis; Approximately 65.96 ten thousand tons of toluene accumulative total import volumes, increase on year-on-year basisLong 0.7%. Solvent based coating organic solvent kind used is a lot, comprises benzene class, ethers, ester class, ketone, alcohols, alcohol ethers, hydrocarbonThe solvent of 10 much classes such as class, adds that low molecule-type auxiliary agent all may evaporate in atmosphere, and some benzene class, alkoxide, be not onlyBelong to " two high " product (" the comprehensive register of environmental protection (version in 2012) ", by " high pollution, high environmental risk " product referred to as: " twoHigh "), and have plenty of " three cause " class material (that is: carcinogenic, mutagenesis, teratogenesis).
It is reported, the great acute occupational poisoning data of organic solvent of collecting between 1989 to 2003 15 years is describedProperty is analyzed. Data result shows: between 15 years, report altogether 58 of organic solvent Severe occupational poisoning accidents, and poisoning 393 examples, inPoison 48 people that die with poison, total poisoning rate is 51.2%, and always the rate of being poisoned to death is 12.2%. Meanwhile, as national coating output and useMeasure maximum Guangdong, province, since two thousand, annual new occupational disease case all exceedes 400 examples, wherein organic solvent poisoningJust accounted for three one-tenth many, in the occupational disease of Guangdong, threaten maximum kind. In addition, the president of Guangdong Prov. Occupational Disease Preventing &. Treating Hospital Huang Hanlin is situated betweenContinue, since 1988, Guangdong Province has found 17 kinds of novel occupational diseases, and wherein 14 kinds is all organic solvent poisoning.
Architectural Paint in China in 2012 still keeps rapid growth, its output reaches 4,800,000 tons, accounts for coating total output37.8%, amplification reaches 28.02% on year-on-year basis. And aqueous architectural coating (containing coating for internal and external wall) and solvent-borne type Building-coating market output ratioThe about 65.4%:34.6% of example.
Solvent based coating will coexist with other coating within considerable time, and compliant solvent still exists at presentResearch and development, therefore solvent is as being dissolved into the solvent of membrane substance, diluting film forming matter as auxiliary agent, the conduct of promoting dissolution with solvents abilityThe diluent of solution or the research and development of dispersant and application should obtain suitable concern.

Thermosetting acrylic resin refers in structure with certain functional group, in use by adding amino treeFunctional group reactions in fat, epoxy resin, polyurethane etc. forms network structure. Thermosetting acrylic coating has the plentiful of excellenceDegree, gloss, hardness, solvent resistance, weatherability, nondiscolouring in the time of high-temperature baking, not yellowing, and excellent unfading.
Select high solids content (solid content >=70%) without aromatic hydrocarbon thermosetting acrylic resin advantage: 1, because resin is solidBody burden composition is high, and in paint liquid, solvent composition reduces, and resin viscosity reduces, and what in Production and Packaging and construction application, use is organicSolvent or diluent also can be still less, therefore also just reduced the pollution that organic solvent volatilizees to atmosphere, reduce workman and producingRight in journey
Solvent contacts the health harm causing; 2, high solids acrylic resin emulsion also has that production efficiency is high, energyConsumption less, storage and the low outstanding feature of cost of transportation; 3, the coating of preparing also has that the thickness, richness of painting is high, decorative effectThe advantage such as good.
Thermosetting acrylic resin of the present invention refers in structure with certain functional group, in the time of painting by with addFunctional group reactions in the amino resins that enters, epoxy resin, polyurethane etc. forms network structure, general relative point of thermosetting resinSon amount is lower. Thermosetting acrylic coating has excellent richness, gloss, hardness, solvent resistance, weatherability, at high-temperature bakingTime nondiscolouring, brightness reversion not.
2-butyl acetate, chemical formula: C6H12O2; Molecular weight: 116.1583; Viscosity: 0.023 (21 ° of C)/mPas; VolatilizationSpeed: 1.8, belong to the strong solvent of medium rate of volatilization; One of four kinds of isomers of butyl acetate. Be colourless liquid, have fruitThe fragrance of increment, water insoluble. Due to increasingly strict to the requirement of environmental protection in global range, people trend towards reducing firstThe consumption of benzene, dimethylbenzene, ketone equal solvent, acetates oxo solvent meets this requirement. And 2-butyl acetate has poisonProperty is little, residual few, little to harm in use procedure. 2-butyl acetate has good solubility to many materials, industrialCan be used as manufacturing the solvent of nitrocellulose lacquer, acrylic paint, polyurethane paint etc. Also can be used as volatility in printing-ink moltenAgent is the optimal selection that substitutes toluene, xylene solvent. Its solid content >=70% of described high solids content.
Dimethyl carbonate, chemical formula: C3H6O3; Molecular weight: 90.07; Viscosity: 0.625 (25 ° of C)/mPas; Volatilization speedRate: 3.4. Be a kind of low toxicity, environmental-protecting performance excellence, there is the green solvent of good solubility property. Meanwhile, it is a kind of importantOrganic synthesis intermediate, contains the functional groups such as carbonyl, methyl and methoxyl group in molecular structure, have multiple reactivity worth, is giving birth toIn product, have the safety of use, convenient, pollute less, the easy feature such as transport. Because dimethyl carbonate toxicity is less, be that one has" green " chemical products of development prospect.
Acetic acid-2-ethyl butyl ester, chemical formula: C8H16O20, molecular weight: 144.21, viscosity: 7.7 (20 ° of C)/mPas.There are fruit fragrance and faint ester perfume (or spice), can be used for preparing fruits essence, as chlorinated rubber, celluloid, polyvinyl acetateThe solvent of ester, natural oil etc. and paint high boiling solvent. Because acetic acid-2-ethyl butyl ester molecular weight is larger, under normal temperature itsSaturated vapor pressure is very low, for: 2.16(kPa/20 ° of C), rate of volatilization is very slow relatively, and the present invention is substituted: " isophorone "Use as drying retardant.
Whether " 2-butyl acetate+dimethyl carbonate " this mixed solvent, have well thermosetting acrylic resinSolvability, and whether can there is intersolubility between solvent, can judge by two aspects:
First: the intersolubility between solvent.
According to " the similar material of chemical composition easily dissolves mutually, and polar solvent easily dissolves polar substances, nonpolar moltenApolar substance is easily dissolved in agent " principle.
Because thermosetting acrylic resin is apolar substance, and 2-butyl acetate, dimethyl carbonate are non-polar solven.So 2-butyl acetate, dimethyl carbonate easily dissolve thermosetting acrylic resin.
The second, whether be total to a molten good judge index by " solubility parameters " as weighing bi-material.
Hull De Bulande definition: the cohesion matter of material can give quantitatively characterizing by cohesive energy, the interior of unit volume gathersCan be called interior polymers density, its square root is called solubility parameters. In the time that the solubility parameters value of high polymer and solvent approaches, solvent pairIt just has stronger dissolving power.
Thermosetting acrylic resin solubility parameters δ=8.9～9.5,2-butyl acetate δ 1=8.2, dimethyl carbonate δ 2=10.4, poor ︱ δ-δ 1 ︱ of any single solvent and acrylic acid solubility, its difference range is all less than 1.3～1.8. Can find out,In the time that the solubility parameter (δ) of solvent and resin solution approaches or be identical, just represent whole active force phase in its unit volumeWith, at this moment thermosetting acrylic resin all can dissolve in two kinds of single esters solvents.
Certainly, in the time can not find suitable single solvent, can mixed solvent, because the suitable mixed solvent of proportioningSolvability is often large than single solvent.
According to the solubility parameters (δ of mixed solventmix) be the solubility parameters (δ of two kinds of neat solvents1，δ2) linearity add and, δmix=φ1δ1+φ2δ2, in formula, φ1，φ2Be two kinds of solvents shared volume fractions in mixed solvent, desirable mixed solvent is joinedRatio: δmix=φ1δ1+φ2δ2+φ3δ3+·····
Mixed ester kind solvent solubility parameters=2-butyl acetate solubility parameters × 50%+ dimethyl carbonate solubility parameters ×50%
=8.2×50%+10.4×50%
=9.3
Visible, mixed ester kind solvent solubility parameters 9.3 and the thermosetting acrylic resin solubility parameters 8.9～9.5 of designClose. Compared with single solvent, the desirable mixed solvent that associates has greatly improved the dissolving power of solvent self, makes each single moltenAgent molecule interphase interaction and associating intensity are good, the advantage of single solvent can be given full play to and fill a vacancy, more effective by thermosettingBased acrylic resin emulsion is dissolved, is diluted and disperses.
Compare from healthy and environmental angle:
1, the harm position to Human Physiology when conventional organic solvents contacts and toxicity performance:
2, " environmentally friendly solvent " that the present invention selects, the harm position to Human Physiology and toxicity performance:
And the present invention selects the harmfulness of solvent to reduce by control. For example: be strict with workman and dressSafety device, protective garment, protective gloves and safety goggles can individually intercept solvent to skin contact, stop solvent to absorb by skinWith through breathe absorb.
Titanium dioxide and silica mainly play painted and inserts effect.
Described auxiliary agent comprises: one or more in dispersant, levelling agent, defoamer, anti-settling agent.
More than build the preparation method of environmental protection thermosetting acrylic coating: first by high solids content (solid content >=70%), nothingAromatic hydrocarbon thermosetting acrylic resin, 2-butyl acetate, dimethyl carbonate, acetic acid-2-ethyl butyl ester, titanium dioxide, titanium dioxideSilicon, auxiliary agent evenly mix at high speed dispersor in proportion, and the time is 15 minutes; Under normal temperature, the material of mixing is through sand millGrind three times, each approximately 1 hour time, can be used as below finished product when fineness reaches 25 microns. When use, need add curing agent.(coating and curing agent are for packing respectively)
Described high speed dispersor rotating speed is: 600～1400 revs/min.
Mainly rely on cross-linking reaction film forming owing to containing hydroxyl (OH) thermosetting acrylic coating, so add in coatingAdd the curing agent of contain-NCO functional group, make it to make film forming matter to solidify at normal temperatures, film has that chemical resistance is strong, heatproofHeight, good weatherability, stain resistance is strong, self-cleaning good, the life-span is long.
Generally: OH] with NCO] and ratio in 1:(1～1.4) be advisable. As OH]: NCO] < 1, be coated withFilm solidifies not exclusively, and drying time is slow, water-fast and chemical resistance is poor; OH]: NCO] > 1.4, the easy embrittlement of film,Have crackle, and product cost rises.
The invention has the beneficial effects as follows:
1, the present invention solves main green technology problem from resin, solvent and three aspects of drying retardant of selecting, selects " heightSolid content (solid content >=70%), without aromatic hydrocarbon thermosetting acrylic resin+2-butyl acetate+dimethyl carbonate+secondAcid-2-ethyl butyl ester ", the acrylic resin, toluene, dimethylbenzene, cyclohexanone, the CAC that in producing with this alternative traditional coating, useEtc. toxic solvent and Poisoning drying retardant, isophorone. The coating of preparation not only meets the technical indicator of solvent based coating, againMeet environmental requirement.
2, coating is easily constructed; Improve the levelability of film, improve flatness, the glossiness of coating, prevent that stream from appearring in filmHang phenomenon.
3, film has that chemical resistance is strong, resistance to acids and bases, resistance to water, temperature-change resistance, good weatherability, stain resistance are good, fromThe features such as clean property is strong, film long service life.
