(1) phthalic anhydride that will take by weighing in proportion, hexanodioic acid, TriMethylolPropane(TMP), neopentyl glycol and dimethylbenzene input have in the reactor of water trap and are warming up to about 110 ℃, start stirring after thing melts substantially in the described reactor, are warming up to 130-140 ℃ and begin to reflux;
(2) constantly emit the water and the weighing of generation, continue to heat up, stopping to discharge water to 190 ° begins insulation, and temperature control is between 190-210 ℃;
(3) treat that the water trap solvent is clear, polyester resin solution acid number in the measured reaction pot, until reaching acid number 15-20, reaction terminating is cooled to 50 ℃ with 1-Methoxy-2-propyl acetate and N-BUTYL ACETATE latting drown;
(4) sampling, by the technical indicator test performance qualified after, filter discharging.
Preparation method as the anti-asphalt paint of fourth aspect present invention, be made up of following steps:
(1) at room temperature, acrylic resin and the vibrin for preparing are added in the paint cylinder, whipped state adds dimethylbenzene and N-BUTYL ACETATE down, dissolving evenly, tested viscosity behind 25-30s (being coated with-4 glasss) homogeneous solution A is stand-by;
(2) add urethane resin in step (1) gained homogeneous solution, at room temperature, middling speed stirs and got solution B in 2 hours;
(3) stirring at low speed is transferred in stirring, in step (2) gained solution B, is added aminoresin, stirred 10 minutes; With the aminoresin homodisperse open solution C,
(4) in step (3) gained solution C, add PMA and TSP, continue stirring at low speed and got solution D in 10 minutes;
(5) in step (4) gained solution D, add MIBK, regulate viscosity, by the qualified back discharging of technical indicator test performance to 25-35s (being coated with-4 glasss).
Described acrylic resin adopts high 4050 acrylic resins that chemical industry company limited produces of putting; 138 aminoresin that described aminoresin adopts Aksu company to produce; The D2 urethane resin that described urethane resin adopts Degussa company to produce;
Described TSP is the modest company of a moral product.
The rotating speed that described middling speed stirs is 800r/s, and churning time is 2 hours; The middling speed mixing speed is fast, produces heat energy and improves temperature, and urethane resin is dissolved in the short period of time.
Described stirring at low speed rotating speed is 400r/s, and churning time is 10 minutes; Stirring at low speed is opened the aminoresin homodisperse.
Anti-contamination mechanism of the present invention:
The mechanism of the anti-contamination of anti-asphalt paint of the present invention is its fine and close structure and enough low surface tension, the present invention uses an amount of D2 urethane resin, the D2 urethane resin promptly can react with the acrylic resin or the vibrin of hydroxyl again with the aminoresin reaction, effectively increase the cross-linking reaction point, increased cross-linking density.The D2 resin is compared with aminoresin simultaneously, and lower surface tension is arranged.
The principle that the present invention adds the small amount of polyester resin is, the easier rotation of the vibrin of line style, and can well remedy can not be fully than inflexible vinylformic acid and the problem of aminoresin reaction, thereby increase cross-linking density, improves the compactness of paint film.
It is a kind of high molecular weight solvent that contains tensio-active agent that the present invention adds a small amount of TSP, and the adding of TSP can effectively reduce the surface tension of paint film.
Like product compares: color special dragon: 006/010808/01; Bright Ke Weize: RF20-0000/1; Ippon: SP110DK coating varnish; PPG:DCC62009.The present invention has improved contamination resistance, erosion resistance and the hardness of paint film greatly under the situation that does not reduce sticking power, weathering resistance, gloss and condition of surface.
Owing to adopted technique scheme, anti-asphalt paint of the present invention to have fine and close structure and enough low capillary characteristics, because have the advantage that preferable anti-pitch stains.
