The alkyd resin is compounded with tolylene diisocyanate affixture or tripolymer. The coating has high adhesion, high hardness, high wear resistance, high shock resistance, good weather resistance, less volatile and other advantages, and the paint may be sprayed or brushed.
Description
Technical field
The invention belongs to technical field of coatings, tool is local to be said, is a kind of modified alkyd resin of extra short oil terminal hydroxy group of modification.
Background technology
Polyurethane paint is a kind of coating of excellent property, be widely used in furniture decoration, application, architectural decoration, aspects such as equipment anticorrosion, this lacquer common affixture or tripolymer by polyester or Synolac and toluene diisocyanate, add that the auxiliary agent allotment forms, the hard floor paint that modulates often ftractures easily because of the specificity of its execution conditions and environmental requirement, and gloss is on the low side, sticking power is bad, the easy yellowing of paint film, hardness is low, not wear-resisting, guarantor's light tint retention is poor, cause the generation of above-mentioned reason, the performance of Synolac plays critical effect, therefore prepares high performance Synolac, is the key problem in technology that solves the many defectives of hard floor paint.
Summary of the invention
The objective of the invention is to overcome existing technical disadvantages, a kind of modified alkyd resin that is used for hard floor paint is provided.
Modified alkyd resin formula for raw stock of the present invention is:
Lauric acid 12～16%, phenylformic acid 0.8～1.6%, hexanodioic acid 4～7.2%, TriMethylolPropane(TMP) 16～20%, neopentyl glycol 6.4～8.8%, phthalic anhydride 28～33.6%, tetramethylolmethane 4～4.8%, M070 lose lustre agent 0.01～0.02%, PST-2 oxidation inhibitor 0.01～0.02%, dimethylbenzene 18～20%, above-mentioned percentage ratio is 100 in the starting material gross weight.
The concrete preparation process of Synolac of the present invention:
With the moon lose lustre 3.5% dimethylbenzene of agent, PST-2 oxidation inhibitor and raw material gross weight of silicic acid, phenylformic acid, hexanodioic acid, TriMethylolPropane(TMP), neopentyl glycol, phthalic anhydride, tetramethylolmethane, M070 once drop into reactor, start when being heated to 90 ℃ and stir, logical CO
2Protection heats up, and is warming up to 160 ℃ with 10 ℃ of/hour heat-up rates, is incubated 1 hour; this moment, refluxing xylene continued to rise to 200 ℃ ± 5 ℃ with 10 ℃ of/hour heat-up rates, was incubated 4～8 hours; when 25 ℃ of survey Ge Shi pipe viscosity are 160S/25 ℃; be cooled to 160 ℃ rapidly, obtain modified alkyd resin, change adding residue dimethylbenzene in another still over to; mix; obtain water-white Synolac liquid, filter and package, the performance index of alkyd resin solution:
Acid value :≤10mgKOH/g
Viscosity: 20000 ± 2000CPS/25 ℃
Solids content: 80 ± 2%
Hydroxyl value: 120
Oil content: about 17～20%.
With 1: 1 adding assistant of TDI (tolylene diisocyanate) affixture that Synolac of the present invention and flower king paint company are produced, can be made into the coating on special-purpose floor.
Raw material of the present invention is the market sale product, wherein said month silicic acid is that Malaysian natural fats and oils company limited produces, phenylformic acid is produced for the chemical plant, Wuhan, hexanodioic acid is that Bayer chemical industry company limited produces, TriMethylolPropane(TMP) and neopentyl glycol are that MIT produces, phthalic anhydride is that Boulder chemical plant, Hubei produces, tetramethylolmethane is produced for the chemical plant, Yichang, the M070 agent of losing lustre is that Bayer chemical industry company limited produces, and PST-2 oxidation inhibitor is that Sweden Bai Situo chemical industry company limited produces.
Advantage of the present invention and effect:
The modified alkyd resin that the present invention makes has extra short oil, so oil content is 17～20% to be difficult for yellowing, add hexanodioic acid, increase resin flexible toughness, the gloss and the hardness that add phenylformic acid, raising resin, add neopentyl glycol, increase and protect the light tint retention, reduce the viscosity of resin and improve compatibility and water tolerance, anti-solvent, good heat resistance.
The affixture or the tripolymer of prepared modified alkyd resin of the present invention and tolylene diisocyanate are made hard floor paint, have preferable performance, higher hardness, not easy to crack, be difficult for yellowing, elasticity and sticking power have good workability, brush, all can spray preferably.
