Embodiment 1

[0013] Embodiment 1--making 4000 kilograms of modified rosin resins:

[0014] Raw materials used: 2200 kg of primary rosin; 400 kg of fumaric acid; 600 kg of glycerin; 794 kg of low iodine value fatty acid; 0.4 kg of anthraquinone; 2,6-di-tert-butyl-p-cresol 2 kg; 4,4-bis(6-tert-butyl-m-cresyl)thiophenol 1.2 kg; Trinonylphenyl phosphite 0.4 kg.

[0015] The production steps are:

[0016] (1) Put 2,200 kg of first-grade rosin into the melting kettle, pass through carbon dioxide gas protection, heat up to 200°C to melt the rosin, and pump it into the esterification pot after it is completely melted;

[0017] (2) Keep feeding carbon dioxide gas protection, start stirring, put in 400 kg of fumaric acid, raise the temperature to 200°C, and keep it warm for 1 hour;

[0018] (3) Add 0.4 kg of anthraquinone, 2 kg of tris(2,4-di-tert-butylphenyl) phosphite, 0.6 kg of 4,4-bis(6-tert-butyl-m-tolyl)thiophenol, 600 kg of glycerin, 794 kg of low iodine value fatty acids, slowly heated up...

Abstract

The invention discloses modified rosin resin and belongs to the technical field of chemical industry. The modified rosin resin comprises, by weight, 55-60% of first-grade rosin, 5-10% of fumaric acid, 15-24.82% of glycerol, 10-20% of low-iodine-value fatty acid, 0.01-0.05% of anthraquinone, 0.02-0.05% of tri-(2, 4-di-tertiary butyl phenyl) phosphite ester, 0.01-0.05% of 2, 6- di-tertiary butyl p-cresol, 0.03-0.05% of 4, 4-di-(6-tertiary butyl-m-methylphenyl) thiophenol, and 0.01-0.05% of tri-nonyl phenyl phosphite ester. The modified rosin resin can solve the problem that road paint prepared is prone to discolor and poor in liquidity during actual production and application processes.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a rosin resin used for producing road paint. Background technique [0002] Generally, the modified rosin resin used in the production of horse route paint is through the addition reaction of rosin and maleic anhydride or fumaric acid, so that the conjugated double bond disappears, the chemical properties are stable, and the tendency of oxidative discoloration is reduced, and then it is esterified with polyols. Chemical reaction, reduce the acid value of the product, increase the softening point, so as to meet the use requirements. However, due to the easy oxidation of rosin, there are still problems in the actual production and application of road paints such as easy discoloration after paint making and poor fluidity. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a modified rosin resin, which can solve th...
