Embodiment 1

[0063] Specific examples to which the two-component coating agent of the present invention is applied will be described in detail below.

[0064] First, the main ingredients constituting the two-component coating agent and the curing agent were respectively combined to prepare samples of Examples 1 to 9 of the present invention and Comparative Examples 1 to 6 shown in Table 1 below.

[0065]

[0066] The main ingredient is prepared by adjusting the respective content ratios of acrylic resin, urethane resin, silicone, fluorine-containing water, and mineral oil. At this time, the proportion of the fluororesin contained in the fluorine-containing water was 10% by mass relative to the total mass of the fluorine-containing water. In addition, the curing agent is produced by adjusting the contents of isocyanate and carbodiimide compound contained therein. The proportion of the cross-linking component represented by carboimide compound contained in the curing agent is 38% to 42%,...

Abstract

In order to provide a two-component coating agent that can prevent deterioration of the surface of a coated body, such as leather and cloth, for a long period of time, as well as strongly preventing stain adhesion, and that can form, on the surface of the coated body, a coating film that has excellent water resistance, abrasion resistance, texture, etc., the present invention is characterized in that, in a two-component coating agent comprising at least a main agent and a hardening agent, the main agent contains a fluorocarbon resin and contains 3-20 mass% acrylics, 3-20 mass% silicone, 40-90mass% water containing the fluorocarbon resin, and 3-50 mass% mineral oil with respect to the total mass of the main agent, the hardening agent contains a crosslinking component comprising a carbodiimide compound, and the mass of the fluorocarbon resin / the mass of the crosslinking component after mixing the main agent and the hardening agent is 1 to 4.

Description

technical field [0001] The present invention relates to a two-component coating agent suitable for forming a film excellent in stain resistance, abrasion resistance, water resistance, texture, etc. on the surface of a coating, and a coating protection method using the coating agent. Background technique [0002] Conventionally, a cloth seat or a leather (leather) seat is used for a car seat or the like. Among them, with respect to leather seats, various finishing methods have been studied from the viewpoint of preventing contamination and abrasion of the surface and improving texture. [0003] The most traditional method of finishing the leather surface is natural color finishing (Su Shi Shang げ). No coloring agent or finishing agent is used in this natural color finishing, only some dyes are used according to the situation, and the color of the leather itself is brought out as a whole only by rolling and polishing. In particular, so-called tanned leather (ヌメ leather) that...
