Embodiment 1

[0090] Example 1 Production Example 1 of Fatty Acid for Resin Modification

[0091] To 100 parts of N / B linseed oil (Nissin Oil Co.), add 40 parts of ion-exchanged water, 0.1 part of lipase OF (Meito Industry Co., Ltd.), carry out decomposition reaction at 37° C. for 10 hours, after standing, Remove the water, re-add the same amount of ion-exchanged water, and then carry out the decomposition reaction for about 5 hours, wash with water, remove impurities by adsorption with activated clay, and distill and purify at 200°C to obtain 70 parts of resin modification with a decomposition degree of 97%. fatty acid.

[0092] Table 1 shows the measurement results of the unsaturation residual index, color number (Gardner) and trans acid content of the obtained fatty acid for resin modification.

Embodiment 2  manufacture example 2

[0094] Add 40 parts of ion-exchanged water and 0.1 part of lipase QL (Meito Industry Co., Ltd.) to 100 parts of N / B linseed oil (Nisshin Oil Co., Ltd.), carry out decomposition reaction at 37° C. for 5 hours, and after standing, Remove water, re-add the same amount of ion-exchanged water, and then carry out the decomposition reaction for about 2 hours. After washing with water, remove impurities with activated carbon to obtain 80 parts of fatty acids for resin modification with a decomposition degree of 60%.

[0095] Table 1 shows the measurement results of the unsaturation residual index, color number (Gardner) and trans acid content of the obtained fatty acid for resin modification.

Embodiment 3

[0096] Example 3 Production Example 3 of Fatty Acid for Resin Modification

[0097] Using 100 parts of soybean oil (Nisshin Oil Co., Ltd.), 70 parts of fatty acids for resin modification with a decomposition degree of 97% were prepared in the same manner as in Example 1.

[0098] Table 1 shows the measurement results of the unsaturation residual index, color number (Gardner) and trans acid content of the obtained fatty acid for resin modification.

Abstract

The present invention provides a modifying agent for resins for paints or resins for inks, containing fatty acids obtained by the enzymatic decomposition of vegetable oils or fats, the resins for paints or resins for inks modified with the modifying agent, and a paint or ink composition containing the resin for the paint or resin for the ink. The paint or ink composition of the present invention has electrodeposition potential or UV curing property and is excellent in the appearance of the paint film, finishing sharpness and adhesion.

Description

Background of the invention [0001] The invention relates to a room temperature drying or baking type water-based coating and electrophoretic coating composition for surface processing of automobiles, ships, strong and weak current equipment, construction machinery, agricultural machinery, and household appliances, or a composition for paper, plastics, etc. , wood, etc., especially relates to a vegetable oil fatty acid obtained by enzymatically decomposing oil as a modifier, curing agent, etc. for coating or ink resin, so that the coating or ink composition has excellent throwing power , coating appearance, surface coating freshness, adhesion, etc. [0002] Industrially, the methods for obtaining fatty acids by decomposing vegetable oils include sulfuric acid decomposition (Twitchell E, 1897), high-temperature alkali cracking and acidolysis and thermal separation combined method (patent-opening No. 49-124103 bulletin), continuous high-pressure decomposition method (Victor- Mil...
