Abstract

The invention discloses a preparation method of an epoxy olefin and olefin ether modified polymerized rosin resin. The method comprises the following steps: S1, adding 100 parts by weight of polymerized rosin resin acid to a solvent, heating the obtained solution to 50-150 DEG C, adding 0.2-6 parts of an organic alkali ammonium catalyst after the polymerized rosin resin is melted, dropwise addingan epoxy olefin and olefin ether raw material within 0.5-1 h, heating the obtained solution to 50-180 DEG C, and stopping heating when the acid value of the polymerized rosin resin in the reaction isnot more than 6 mg KOH / g; and S2, continuously adding the solvent, neutralizing the organic alkali catalyst with an acid agent, washing the above obtained product with water to obtain a substrate, carrying out reduced pressure distillation on the substrate at 50-180 DEG C, and drying the obtained product to obtain the epoxy olefin and olefin ether modified polymerized rosin resin. The epoxy olefinand olefin ether modified polymerized rosin resin prepared in the invention has the characteristics of good tackifying effect, good initial tack and good flexibility.

Description

technical field [0001] The invention belongs to the field of rosin deep processing, and in particular relates to an epoxy olefin and olefin ether modified polymerized rosin 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 fun...
