Abstract

Relating to the technical field of chemical industry, the invention discloses a petroleum resin modified rosin resin dispersion and a preparation method thereof. The petroleum resin modified rosin resin dispersion comprises the following components by weight: 470-500 parts of rosin, 20-25 parts of maleic anhydride, 1.2-1.8 parts of a nonylphenol sulfide oligomer, 9-11 parts of propylene glycol, 120-135 parts of petroleum resin, 1.5-1.8 parts of 0.5mol / L potassium hydroxide aqueous solution, 60-90 parts of a hydrophilic reagent, and 550-600 parts of hot water. Compared with the prior art, the invention adopts a reverse technological method to disperse resin into dispersions with a size of 0.15micrometer-1micrometer. The dispersion can be prepared into a waterborne adhesive together with rubber latex or carboxylic butadiene-styrene latex or acrylic latex and the like. The waterborne adhesive has good initial adhesion, peel strength, permanent adhesion and the like, and can reach the market required index.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a petroleum resin modified rosin resin dispersion and a preparation method thereof. Background technique [0002] Petroleum resin is named after the source of petroleum derivatives. It is a thermoplastic resin produced by the C5 and C9 fractions produced by petroleum cracking by pretreatment, polymerization, distillation and other processes. It has low acid value and good miscibility. It is resistant to water, ethanol and chemicals, chemically stable to acid and alkali, and has the characteristics of good viscosity adjustment and thermal stability. Petroleum resins are generally not used alone, but used together as accelerators, modifiers, modifiers and other resins to improve or increase certain characteristics of the product. [0003] Rosin resin, made from rosin through a series of reactions, has high softening point, high viscosity, and better oxidation resistance,...
