Abstract

The invention discloses epoxy-based alkene and alkene ether modified rosin phenol resin and a preparation method thereof. The preparation method comprises the following steps: reacting a phenol-sourced reagent and rosin under the acid catalyzing condition to prepare rosin phenol resin acid; adding 100 weight parts of the rosin phenol resin acid prepared in S1 into a solvent B, and heating to 50-150 DEG C; melting the rosin phenol resin, adding 0.2-6 weight parts of an organic alkali ammonium catalyst; dropwise adding epoxy-based alkene and alkene ether raw materials for 0.5-1 hour, regulatingthe temperature to 50-180 DEG C, and stopping reacting when the acid value of the product is not more than 6mg KOH/g; supplementing a solvent B after the reaction is stopped, and adding acid to neutralize the organic alkali ammonium catalyst; rinsing to obtain substrate, and distilling the substrate at reduced pressure at 50-180 DEG C to obtain epoxy-based alkene and alkene ether modified rosin phenol resin. The epoxy-based alkene and alkene ether modified rosin phenol resin have the characteristics of high reaction activity and good tackifying effect.

Description

technical field [0001] The invention belongs to the field of deep processing of rosin, and in particular relates to an epoxy olefin and olefin ether modified rosin phenol resin and a preparation method thereof. Background technique [0002] With the increasing improvement of global human science and technology life, it will become an inevitable trend of sustainable development for people to look for non-polluting and renewable resources that can replace petrochemicals between resource acquisition and environmental protection. Therefore, the green and recyclable biomass rosin Materials are reprocessed into various polymer materials, which have a wide range of applications due to their special chemical and physical properties. Rosin has the advantages of large output, green and environmental harmony, renewable, biodegradable, etc., and it contains a stable triple ring rigid structure, so it has the potential to replace petrochemical aromatic ring raw materials to prepare funct...
