Problems solved by technology

However, there are problems that these thermoplastic polyolefin resins are inferior in surface adhesion, scratch resistance, abrasion resistance, and chemical resistance compared with conventionally used vinyl chloride resins. In order to improve these problems, it is necessary to modify the surface give functionality
However, it is still not enough to deal with the current environmental protection on a global scale.

Embodiment

[0169] Hereinafter, specific manufacturing examples, examples, and comparative examples are given to explain the present invention in further detail, but the present invention is not limited to these examples. In addition, unless otherwise specified, "parts" and "%" in the following examples are quality standards.

[0170] (Production of modifier)

[0171] 100 parts of trimethylolpropane and hexamethylene diisocyanate tripolymer adduct [CoronateHL (trade name), manufactured by Nippon Polyurethane Co., Ltd., NCO=12.9%, solid content 75%], 24.5 parts of ethyl acetate While fully stirring at 100°C, 25.5 parts of ε-caprolactam was added and reacted for 5 hours. According to the infrared absorption spectrum of the modifier obtained (Horiba FT-720), at 2,270cm -1 Absorption due to free isocyanate groups remained at the place. When the free isocyanate groups were quantified, the theoretical value was 2.1% based on the solid content of 50%, compared to the actual measured value of 1.8%. ...

manufacture example 4

[0182] (Production of 5-membered cyclic carbonate compound)

[0183] The divalent epoxy compound represented by the following formula A [epikote 828 (trade name), manufactured by Nippon Epoxy Co., Ltd., epoxy resin) is added to a reaction vessel equipped with a stirrer, a thermometer, a gas introduction tube, and a reflux condenser. Equivalent of 187g / mol] 100 parts, 100 parts of N-methylpyrrolidone, 1.5 parts of sodium iodide, and uniformly dissolve them.

[0184]

[0185] Then, while blowing carbon dioxide at a rate of 0.5 L / min, heating and stirring were performed at 80°C for 30 hours. After the reaction, while stirring at 300 rpm at high speed, the obtained solution was slowly added to 300 parts of n-hexane, the resulting powdery product was filtered with a filter, and washed with methanol to remove N-methylpyrrolidone and iodine Sodium. The powder was dried in a dryer to obtain 118 parts of a white powdery 5-membered ring cyclic carbonate compound (1-A) (yield 95%).

manufacture example 5

[0187] (Production of 5-membered cyclic carbonate compound)

[0188] The divalent epoxy compound [YDF-170 (trade name), manufactured by Toto Kasei Co., Ltd., epoxy equivalent 172 g / mol] represented by the following formula B was used instead of the divalent epoxy compound A used in Production Example 4, and Production Example 4 was reacted in the same manner to obtain 121 parts of white powdery 5-membered cyclic carbonate compound (1-B) (yield 96%).

[0189]

[0190] As in the case of Production Example 4, the product was confirmed by infrared absorption spectrum, GPC, and NMR. 20.3% of carbon dioxide was immobilized in the obtained 5-membered cyclic carbonate compound (1-B).

Abstract

A self-crosslinkable polyhydroxy polyurethane resin which is prepared by the reaction of a five-membered cyclic carbonate compound and an amine compound and which has masked isocyanate groups in the structure; a process for the production of the polyhydroxy polyurethane resin; an imitation leather obtained by filling or laminating a base fabric with a resin composition that comprises the polyhydroxy polyurethane resin as the main component; a surfacing material made of a thermoplastic polyolefin resin, which includes a thermoplastic polyolefin resin sheet and a top coat layer formed on the sheet either directly or with a primer layer interposed therebetween and in which the top coat layer is a layer formed from a resin composition that comprises the polyhydroxy polyurethane resin as the main component; and a weatherstrip material which comprises the polyhydroxy polyurethane resin and a specific diorgano- polysiloxane and / or a specific silicone oil as the main components.

Description

Technical field [0001] The present invention relates to a new type of self-crosslinking polyhydroxy polyurethane resin, a resin material containing the resin and a manufacturing method thereof. In more detail, it relates to a technology for providing a self-crosslinking polyhydroxy polyurethane resin that is used in film forming materials, various coating materials, various coatings, and various adhesives. In the case of forming materials such as mixtures, products with excellent abrasion resistance, chemical resistance, and heat resistance can be made. Moreover, carbon dioxide is used in the manufacturing raw materials and the carbon dioxide can be fixed in the resin, thus preventing the global environment The point of view of destruction is also useful. [0002] The present invention relates to an artificial leather using a resin composition containing the above-mentioned self-crosslinking polyhydroxy polyurethane resin as the main component. More specifically, it relates to an...
