The preparation method of a kind of low VOC content alkydpaints provided by the invention is at first in Scattered Kettle, drop into 25 parts-35 parts modified alkyd resin, 0.3 part of-0.8 part of dispersion agent, 10 parts of-28 parts of pigment, 5 parts of-10 parts of fillers, 2 parts-4 parts solvent, carry out high speed dispersion evenly after, adding 1 part of-2 parts of interface stablizer stirs evenly, grind again and be dispersed to fineness and reach requirement, add remaining 15 parts of-35 parts of modified alkyd resins, 0.3 part of-0.6 part of siccative, 0.2 part of-0.5 part of anti, 10 parts of-15 parts of water and stir, adjust viscosity with 2 parts of remaining-4 parts of solvents.
Described modified alkyd resin is to obtain by following method, at one agitator is housed, condenser, in the reactor of well heater, be weighed into the 22g-30g vegetables oil, be warmed up to 120 ℃ and add the 2g-6g tetramethylolmethane in batches, after adding, be warmed up to 250 ℃ with 2 hours-3 hours, add the useless Coke bottle sheet of 12g-20g in batches, after adding, under 250 ℃-260 ℃, be incubated transparently, cool to 200 ℃ and add the 5g-8g rosin to material, the 2g-6g Tetra hydro Phthalic anhydride, the 1g-3g MALEIC ANHYDRIDE, 1.5g backflow dimethylbenzene, in 200 ℃ of reactions 2 hours, be warmed up to 220 ℃ and insulation again, when acid number is lower than 26mgKOH/g, is weighed into the 38g-44g200 industrial naptha and carries out latting drown.The Synolac solid content of gained is 55 ± 2%, and viscosity is 75KU-85KU, and acid number is 10mgKOH/g-15mgKOH/g.
Core of the present invention is to select modified alkyd resin for use, in the presence of dispersion agent, interface stablizer, with water to stable dispersion in alkydpaints, keep long-time stable, and in construction process, have no adverse reaction, considerable change does not take place in performances such as dried paint film appearance, gloss, sticking power, hardness, water tolerance.
The coating package stability is the result of each component interphase interaction.The Synolac of modification is being arranged, dispersion agent, pigment, filler, in the compositions such as interface stablizer and water, utilize dispersion agent, the hydrophilic segment of interface stablizer and oleophilic moiety, at modified alkyd resin, pigment, form the multilayer adsorption layer between solvent and water, it mainly is the hydrophilic group that utilizes dispersion agent and interface stablizer end, hydrophobic group, water molecules and dispersion agent with miniaturization, the hydrophilic group of interface stablizer end, Van der Waals force and electrostatic forcing that hydrophobic group produces, the absorption of formation multilayer, stablize coating, and utilize the Synolac and the dispersion agent of modification, fabulous intermiscibility between the interface stablizer obtains a complete stabilising system.
Alkydpaints with this preparation method produces exists multiple interface in coating, this has changed paint flow variant system, produces thixotropic behavior, makes that color stuffing is difficult for producing precipitation in the paint, and paint film disadvantage such as reduced loose colour, grow dim is difficult for producing sagging in the construction.
By the effect of tensio-active agent, improved the wetting dispersion of pigment, can reduce amount of pigment, improve the coating package stability, reduce production costs.
In solvent evaporates and coating film process, interface effect by dispersion agent and interface stablizer and modified alkyd resin, non-polar solvent helps steadily evenly volatilization of moisture content, makes the interface stablizer can fill up the space that stays after the water volatilization, make coating surface smooth smooth, paint film property is good.
Coating of the present invention has following advantage:
Product does not contain benzene, and shelf-stable is not stratified, and fabulous application property is arranged, lower VOC content, and save energy reduces environmental pollution, reduces manufacturing cost, and product performance reach industry standard, and economic benefit is good.
