Description
Technical field
The present invention relates to gasoline paint preparation field, be specifically related to shock-resistant, high adhesive force and snappiness saturated polyester resin and preparation method thereof.
Background technology
The most frequently used saturated polyester resin of coating industry is the vibrin containing terminal hydroxy group functional group, by with the resin crosslinks such as isocyanic ester, aminoresin film-forming.Saturated polyester resin (oil-free alkyd resin), mainly for the production of coil coating, according to the finish paint that difference respectively can be used for coil coating, priming paint, the back of the body paint of resin property with structure, also has the saturated polyester resin for ink and hot overlay film coiled material.Oil-free alkyd resin is a kind of high molecular weight linear saturated polyester resin, is mainly used in hot overlay film coiled material and sticks with glue agent and coil coating priming paint, has excellent adhesiveproperties and the balance quality of good Hardness and toughness.Oil-free alkyd resin, film has splendid snappiness, good with the wettability of pigment, and not easily yellowing, to protect light tint retention good, and high, the resistance to paint baking over of gloss, is mainly used in the industries such as tin printing ink.But, in car refinishing paint field, temporarily a retouching paint is not also had to be introduced by saturated polyester resin, and what the indices performance of saturated polyester resin all played is good, this greatly constrains the Application Areas of saturated polyester resin undoubtedly, and meanwhile, car refinishing paint field is also being sought how to allow retouching paint have better impact resistance always, and possess preferably snappiness and high adhesive force, this is a worth problem studied beyond doubt.
Disclose the patent of invention that name is called " a kind of car refinishing paint Hydroxylated acrylic resin and preparation method thereof " in the Chinese patent that application number is " 201310066010.0 ", its technical scheme is as follows: the weight proportion of each reactant is: alkyl methacrylate 30-50 part; Hydroxy acrylate 10-20 part; Vinylbenzene 10-20 part; Unsaturated carboxylic acid 0.5-1.5 part; Fluorinated acrylate 1.0-3.0 part; Initiator 1-3 part; Solvent 30-40 part.The present invention starts with from the filmogen resin of coating, particularly start with from the adjustment of the monomer structure of resin and realize coating surface drying and internal chemical are cross-linked very fast, there is lower shrinkage, high gloss, high clarity, advantage that scratch resistant performance is good, but it can not be applied to some needs to have in the car refinishing paint field of good impact resistance and higher snappiness and adhesion property.
Application number is in the Chinese patent of " 201210399810.X ", discloses name and is called that " a kind of preparation method of retouching paint of the automobile acrylic resin of resistance to alcoholic extract hydroxyl group " its technical scheme is as follows: (1) prepares the raw material of following components by weight percent: the acrylic resin of resistance to alcoholic extract hydroxyl group: 100 parts; Dispersion agent: 3-5 part; Nano titanium oxide: 1 part; Pimelinketone: 0-0.5 part; Epoxy hardener: 2-2.5 part; Solvent 1:20-25 part, wherein, described dispersion agent is macromolecule dispersing agent, and described epoxy hardener is aliphatic diamine, polyamines or aromatic polyamine; (2) above-mentioned raw materials is put into dispersion cylinder, stir 30 minutes under the rotating speed of 1400 revs/min with high speed dispersor; (3) the raw material shredder after stirring in step (2) is ground, after fineness is less than 5um, discharging, the retouching paint of the acrylic resin of resistance to alcoholic extract hydroxyl group of obtained automobile.Car refinishing paint alcohol resistance prepared by the present invention can be strong, resistance to corrosion is high, and solvent is cheap, and preparation technology is simple, but it can not be applied in some car refinishing paint necks needing to have good impact resistance and higher snappiness and adhesion property.
Summary of the invention
Retouching paint how is allowed to have better impact resistance in order to solve, and possess the problem of preferably snappiness and high adhesive force, the invention discloses shock-resistant, high adhesive force and snappiness saturated polyester resin and preparation method thereof, there is better impact resistance, and there is preferably snappiness and higher adhesion property.
Shock-resistant, high adhesive force and snappiness saturated polyester resin, comprise following material composition (by weight percentage): component A (neopentyl glycol 32.93, triphenyl phosphite 0.05, hexanodioic acid 10.16, inclined acid anhydride 6.86, dimethylbenzene 1.46, phthalic anhydride 21.74), B component (trimethylbenzene 26.79).
The making method of shock-resistant, high adhesive force and snappiness saturated polyester resin, comprises following processing step:
(1) successively component A is put in reactor, after finishing, pass into nitrogen by 0.2m3/h, in 2 hours, be evenly warming up to 180 DEG C, and be incubated 2 hours;
(2) in 2 hours, be warming up to 240 DEG C, insulation, detect acid number and viscosity;
(3), as the acid number≤8mgKOH/g (100%) detected, during viscosity 60-65s, cooling, adds B component latting drown.
The index of the product that the present invention prepares is as follows: outward appearance: micro-Huang, clear, transparent; Color and luster :≤3#(FE-CO) number; Admittedly contain: 70 ± 2%; Acid number :≤8mgKOH/g (100%); Viscosity: 4000 ~ 6000mpa.s/25 DEG C.
