Problems solved by technology

The disadvantage is that the toluene and other toxic gases volatilized by the solvent have certain harm and pollution to the human body and the environment. The affinity between the glass beads and the solvent is poor, the glass beads are easy to fall off, the reflective effect at night is not good, and the service life is short. Only use 6- 12 months

Embodiment Construction

[0008] Implementation one:

[0009] (1) By weight, 75%-88% of bit grade gum rosin, 2%-5% of fumaric acid, 1%-5% of maleic anhydride, 3%-10% of ethylene glycol, 5%-10% of pentaerythritol, Oxygen agent 0.5%~4%, zinc oxide 0.5%~4% Weigh each ingredient: (2) Put the special grade gum rosin in molten state into the reactor and heat up to 200°C; (3) Add in order according to the weight ratio in the formula Fumaric acid, maleic anhydride, ethylene glycol, zinc oxide, 50% antioxidant; (4) keep warm for one hour, then add pentaerythritol, heat up to 250-295°C and keep warm for 8-12 hours; (5) sample test, qualified Post-vacuum treatment for 4 hours, add the remaining 50% antioxidant when cooling down, and produce and pack at normal temperature.

[0010] In the sampling test: the Garner color is less than 5, the acid value is less than or equal to 25, and the softening point is greater than or equal to 90 degrees. Nitrogen protection is carried out during the production process of add...

Abstract

The invention relates to a kind of road marking resin, which particularly relates to the road marking resin lipid-modified by the high-quality rosin to replace petroleum resin, acrylic or chlorinated rubber for solving the pollution problem. The material has excellent mobility of construction as well as anti-shed, light resistance, wear resistance, oxidation resistance, water-resistance, pressure resistance, filthy resistance, weather resistance and chemical resistance.

Description

Technical field: [0001] The invention relates to a process flow of road marking resin and its production formula, in particular to a process flow and formula of practical high-quality rosin resin modified by esterifying rosin. Background technique: [0002] Most of the similar road markings produced by the prior art use petroleum resin, acrylic acid or chlorinated rubber: petroleum resin has a low melting point, a wide relative molecular mass distribution, and a large number-average relative molecular mass (Mn), so it is used for road marking paint When the melt viscosity is too high, the fluidity of the product is poor, and it is not easy to process and use; when it is used in adhesives, the thickening effect is not significant, and the water resistance and moisture resistance are poor, and the adhesive layer is easy to creep. Moreover, the cost of petroleum resin is high, the construction is cumbersome, and it will become brittle and fall off at too high or too low tempera...
