Embodiment 1

[0039] 100 g of a mixture containing 50.82% of indene and 4.61% of coumarone and 1.5 g of 4-hydroxystyrene were stirred and mixed at 60° C. to form a reaction solution. The reaction solution was heated to 80° C., and while stirring, 1.0 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., 100 g of water was added and the solution was stirred and mixed for 20 minutes, and the liquid was separated with a separatory funnel. The washed solution was distilled to remove the solvent to obtain 56.8 g of 4-hydroxystyrene-modified coumarone resin. The hydroxyl value of the resin was determined to be 30.75 mgKOH / g.

[0040] Comparative experiment: 100 grams of a mixture containing 50.82% of indene and 4.61% of coumarone was heated to 80°C without adding 4-hydroxystyrene, and while stirring, 1.0 grams of boron trifluoride ether wa...

Embodiment 2

[0043]100 g of a mixture containing 50.82% of indene and 4.61% of coumarone and 3.0 g of 4-hydroxystyrene were stirred and mixed at 60° C. to form a reaction solution. The reaction solution was heated to 80° C., and while stirring, 1.0 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., 100 g of water was added and the solution was stirred and mixed for 20 minutes, and the liquid was separated with a separatory funnel. The washed solution was distilled to remove the solvent to obtain 58.4 g of coumarone resin modified with 4-hydroxystyrene. The hydroxyl value of the resin was determined to be 40.72 mgKOH / g.

[0044] Comparative experiment: 100 grams of a mixture containing 50.82% of indene and 4.61% of coumarone were synthesized without adding 4-hydroxystyrene to obtain 55.4 grams of coumarone resin. The resin had a ...

Embodiment 3

[0047] 100 g of a mixture containing 45.85% of indene and 4.65% of coumarone and 1.5 g of 4-hydroxystyrene were stirred and mixed at 60° C. to form a reaction solution. The reaction solution was heated to 90° C., and while stirring, 0.8 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 40° C., 100 g of water was added and the solution was stirred and mixed for 20 minutes, and the liquid was separated with a separatory funnel. The washed solution was distilled to obtain 52.1 g of coumarone resin modified with 4-hydroxystyrene. The hydroxyl value of the resin was determined to be 31.73 mgKOH / g.

[0048] Comparative experiment: 100 grams of a mixture containing 45.85% indene and 4.65% coumarone was heated to 90°C without adding 4-hydroxystyrene, and while stirring, 0.8 grams of boron trifluoride ether was added dropwise for co...

Abstract

The invention provides a hydroxyl coumarone resin and preparation method thereof, and belongs to the field of resin preparation. The hydroxyl coumarone resin is prepared from a polymerizable component-containing mixture and 4-hydroxystyrene or 4-hydroxyl methyl cinnamate or 4-hydroxyl ethyl cinnamate, and the polymerizable component-containing mixture is obtained through distilling a heavy benzene fraction of coal tar; and polymerizable components comprise indene and coumarone, and the mass of 4-hydroxystyrene or 4-hydroxyl methyl cinnamate or 4-hydroxyl ethyl cinnamate is 1-20% of the mass of the polymerizable components. The hydroxyl coumarone resin contains hydroxyl groups, so the hydroxyl value of coumarone resin is substantially improved, and the coumarone resin has good compatibility with polar resins; and the coumarone resin carrying the hydroxyl groups chemically reacts with other components to form interpenetrating network crosslinking, so the performances of coatings and adhesives are further improved.

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 hydroxy coumarone resin and a preparation method thereof. Background technique [0002] Indene-coumarone (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 prepared adhesive has significantly enhanced adhesion, and can be miscible with paraffin wax and vinyl resin to produce a 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, reputation writin...
