Embodiment 1

[0043] 200 g of a mixture containing 50.82% of indene and 4.61% of coumarone and 6.0 g of methyl methacrylate were stirred and mixed at 60° C. to form a reaction solution. The reaction solution was heated to 80° C., and while stirring, 2.0 g of boron trifluoride etherate complex was added dropwise, and the reaction was continued for 30 minutes after the initiator was added dropwise. Cool the polymerized solution to 30° C., add 200 g of water and stir the solution for 20 minutes, separate the water with a separatory funnel. The solution after washing with water was distilled, and the solvent and the monomer were removed by atmospheric distillation to obtain 116.3 grams of carboxycoumarone resin modified with methyl methacrylate.

[0044] Comparative experiment: 200 grams of a mixture containing 50.82% of indene and 4.61% of coumarone was heated to 80°C without adding methyl methacrylate, and while stirring, 2.0 grams of boron trifluoride ether was added dropwise for complexatio...

Embodiment 2

[0047] 200 g of a mixture containing 50.82% of indene and 4.61% of coumarone and 10.0 g of methyl methacrylate were stirred and mixed at 60° C. to form a reaction solution. The reaction solution was heated to 80° C., and while stirring, 2.0 g of boron trifluoride etherate complex was added dropwise, and the reaction was continued for 30 minutes after the initiator was added dropwise. The temperature of the polymerized solution was lowered to 30° C., 200 g of water was added and the solution was stirred and mixed for 20 minutes, and the liquid was separated with a separatory funnel to separate the water. The solution after washing with water was distilled, and the solvent and the monomer were removed by atmospheric distillation to obtain 120.2 grams of carboxycoumarone resin modified with methyl methacrylate.

[0048] As can be seen from the above experimental results, compared with the comparative experiment without adding methyl methacrylate in Example 1, the present embodime...

Embodiment 3

[0050] 200 g of a mixture containing 50.82% of indene and 4.61% of coumarone and 6.0 g of ethyl methacrylate were stirred and mixed at 60° C. to form a reaction solution. The reaction solution was heated to 80° C., and while stirring, 2.0 g of boron trifluoride etherate complex was added dropwise, and the reaction was continued for 30 minutes after the initiator was added dropwise. The temperature of the polymerized solution was lowered to 30° C., 200 g of water was added and the solution was stirred and mixed for 20 minutes, and the liquid was separated with a separatory funnel to separate the water. The solution after washing with water was distilled, and the solvent and the monomer were removed by atmospheric distillation to obtain 116.4 grams of carboxycoumarone resin modified with ethyl methacrylate.

[0051] As can be seen from the above experimental results, compared with the experiment without adding ethyl methacrylate in Example 1, the present embodiment adopts the ad...

Abstract

The invention belongs to the field of resin preparation, and in particular relates to a carboxycoumarone resin and a preparation method thereof. The carboxyl coumarone resin is prepared by redistilling the heavy benzene fraction of coal tar to obtain a mixture containing polymerizable components and methacrylate or acrylate; the polymerizable components are indene and coumarone, The mass of the methacrylate or acrylate is 2-15% of the mass of the polymerizable component. The carboxyl coumarone resin has carboxyl groups and has good compatibility with polar resins to further improve the performance of coatings, adhesives and inks; the preparation method has mild conditions, simple process and easy industrial production.

Description

technical field [0001] The invention belongs to the field of resin preparation, and relates to a modified coumarone resin and a preparation method thereof, in particular to a carboxyl coumarone resin and a preparation method thereof. Background technique [0002] Indene-coumarone resin (referred to as: coumarone resin) has excellent properties such as acid resistance, alkali resistance, adhesion, plasticization and reinforcement, and is mainly used in coatings, adhesives, rubber, inks and other related fields. In terms of coating application, Coumarone resin can be made into various coatings, showing excellent acid resistance, alkali resistance and adhesion. In terms of adhesive application, the adhesive made of coumarone resin has significantly enhanced adhesion, and can be miscible with paraffin and vinyl resin to produce hot-melt adhesive or adhesive with high bonding performance. In terms of ink application, it can be applied to news printing ink, offset printing ink, r...
