Summary of the invention
The object of this invention is to provide and can reduce melt viscosity, increase sticking power, weather resistance is high, the resin dedicated and production method of a kind of rosin modified road guide line of good stability.
The technical scheme that the present invention takes is: a kind of rosin modified road guide line is resin dedicated, it is characterized in that its composition by weight is: primary rosin 95～double centner, 0～5 kilogram, 0～5 kilogram of hexanodioic acid and O-phthalic acid mixture, cis-butenedioic anhydride and acrylic acid mixture; 5～15 kilograms of any one or a few alcohol mixtures in ethylene glycol, glycol ether, triglycol, glycerol and tetramethylolmethane; (300) 0～0.5 kilograms, oxidation inhibitor; (700) 0～0.5 kilograms, oxidation inhibitor; (168) 0～0.5 kilograms, oxidation inhibitor; (1010) 0～0.5 kilograms, oxidation inhibitor; 0～0.3 kilogram of high-efficiency compound stabilizer; 0～0.5 kilogram of uv-absorbing agent.
The described resin dedicated production method of a kind of rosin modified road guide line, the resin dedicated composition by weight of its rosin modified road guide line is primary rosin 95～double centner, 0～5 kilogram, 0～5 kilogram of hexanodioic acid and O-phthalic acid mixture, cis-butenedioic anhydride and acrylic acid mixture; 5～15 kilograms of any one or a few alcohol mixtures in ethylene glycol, glycol ether, triglycol, glycerol and tetramethylolmethane; (300) 0～0.5 kilograms, oxidation inhibitor; (700) 0～0.5 kilograms, oxidation inhibitor; (168) 0～0.5 kilograms, oxidation inhibitor; (1010) 0～0.5 kilograms, oxidation inhibitor; 0～0.3 kilogram of high-efficiency compound stabilizer; 0～0.5 kilogram of uv-absorbing agent; It is characterized in that it comprises the following steps: A, carries out heat temperature raising by entering reactor after primary rosin dissolving, when temperature reaches 190 ℃, add oxidation inhibitor (300), oxidation inhibitor (700), cis-butenedioic anhydride and acrylic acid mixture, then be warming up to 220 degree constant temperature 2 hours; B, add any one or a few alcohol mixture in ethylene glycol, glycol ether, triglycol, glycerol and tetramethylolmethane, be warming up to gradually 240 ℃ and keep 3 hours; C, add the mixture of hexanodioic acid and phthalic acid, then with 3 hours, temperature is risen to 270～280 ℃ of constant temperature and carry out esterification sample examination acid number after 6 hours; D, the qualified rear beginning vacuum hydro-extraction of acid number 3 hours; E, dewatered after, when cooling down to 230 ℃ ± 5 ℃, add oxidation inhibitor (168), oxidation inhibitor (1010), high-efficiency compound stabilizer and uv-absorbing agent, fully mix 30 minutes, start discharging granulation.
Adopt the present invention, in the situation that not reducing its heat resistance, greatly reduce the melt viscosity of graticule resin, obviously improved its coating performance; The fragility of having improved it, has increased sticking power; Also obviously improved weather resistance.
Embodiment
The invention will be further described below.The resin dedicated production method of this rosin modified road guide line comprises the following steps:
