Embodiment

[0155] Hereinafter, the present invention will be described in more detail with reference to specific production examples, examples, and comparative examples, but the present invention is not limited to these examples. In addition, unless otherwise specified, "part" and "%" in each of the following examples are based on mass.

[0156] (Manufacturing of Modifier)

[0157]On one side, 100 parts of trimethylolpropane and hexamethylene diisocyanate trimer adduct (CORONATEHL (trade name), manufactured by Nippon Polyurethane Co., Ltd., NCO=12.9%, solid content 75%), and 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 (measured with Horiba FT-720, the same applies below), at 2,270 cm -1 Absorption due to the appearance of free isocyanate groups on the surface, and when the free isocyanate groups are quantified, the theoretical value is 2....

manufacture example 4

[0165] (Manufacture of 5-membered cyclic carbonate polysiloxane compound)

[0166] In a reaction vessel equipped with a stirrer, a thermometer, a gas introduction tube, and a reflux cooler, a divalent epoxy-modified polysiloxane represented by the following formula A (manufactured by Shin-Etsu Chemical Co., Ltd., X-22-163 ( trade name); epoxy equivalent 198g / mol) 100 parts, N-methylpyrrolidone 100 parts, sodium iodide 1.2 parts, and dissolve uniformly. Thereafter, the mixture was heated and stirred at 80°C for 30 hours while passing carbon dioxide at a rate of 0.5 liter / min.

[0167]

[0168] (a is the value when the molecular weight reaches 396)

[0169] After completion of the reaction, 100 parts of n-hexane was added to the obtained solution to dilute it, and then, using a separating funnel, it was washed three times with 80 parts of pure water to remove N-methylpyrrolidone and sodium iodide. The n-hexane solution was dehydrated with magnesium sulfate and then concent...

manufacture example 5

[0171] (Manufacture of 5-membered cyclic carbonate polysiloxane compound)

[0172] The divalent epoxy-modified polysiloxane B represented by the following formula B (Shin-Etsu Chemical Co., Ltd., KF-105 (trade name); epoxy equivalent 485 g / mol) was used instead of the one used in Production Example 4. Divalent epoxy-modified polysiloxane A was reacted in the same manner as in Production Example 4 except that, to obtain 99 parts of a colorless and transparent liquid 5-membered ring carbonate polysiloxane compound (1-B) (Yield 91%).

[0173]

[0174] (a is the value when the molecular weight reaches 970)

[0175] The product was confirmed by infrared absorption spectrum, GPC, and NMR. In the obtained 5-membered ring cyclic carbonate polysiloxane compound (1-B), 8.3% of carbon dioxide was immobilized.

Abstract

The invention provides a self-crosslinking polysiloxane-modified polyhydroxy polyurethane resin which has a polysiloxane segment and a masked isocyanate group in the structure thereof and is derived from a reaction between a five-membered cyclic carbonate polysiloxane compound represented by general formula (1) and an amine compound. The invention also provides a method for producing the same. According to the invention, with respect to a polyhydroxy polyurethane resin, the application of which has not progressed in the prior art, a novel self-crosslinking polyhydroxy polyurethane resin which is capable of providing a product or the like having excellent smoothness, abrasion resistance, chemical resistance, non-adhesiveness, heat resistance, etc., and is useful in terms of reduction of greenhouse gas and therefore is environmentally responsive can be provided.

Description

technical field [0001] The first invention of the present invention relates to a novel self-crosslinking type polysiloxane-modified polyhydroxyurethane resin, a resin material containing the resin, and a production method thereof. More specifically, it relates to a technology of a self-crosslinking polysiloxane-modified polyhydroxyurethane resin used in film / molding materials, various In the case of forming materials such as coating materials and various adhesives, products with excellent slipperiness, abrasion resistance, chemical resistance, non-adhesiveness, and heat resistance can be obtained. Moreover, among manufacturing raw materials Using carbon dioxide, carbon dioxide can be fixed in the resin, so it is also useful from the viewpoint of preventing global environmental damage. [0002] The second aspect of the present invention relates to an artificial leather obtained by using a resin composition mainly composed of the above-mentioned self-crosslinking polysiloxane-m...
