JPH02147668A - Coating material giving suede finish - Google Patents

Abstract

PURPOSE:To obtain the title coating material which can give a coated surface a suede finish when applied by a usual application means by mixing a short fiber, a solvent and a vehicle in a specified ratio. CONSTITUTION:This coating material is prepared from 1-20wt.% short fiber (e.g. nylon) of a length of 0.1-2.0mm, 50-80wt.% solvent for dispersing the fiber (e.g. a xylene/methyl isobutyl ketone/butyl acetate mixture) and 3-60wt.% vehicle (e.g. polyester polyol resin) for adhering the short fiber to the desired part.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a paint that can produce a suede feel after coating and curing, and if it is in a place where people maintain visual, tactile, etc. contact, Although it can be applied to a wide range of areas, it can be applied to, for example, the interior of vehicles, the interior walls of buildings, the interior and exterior surfaces of storage boxes, etc. to create the illusion of suede.

Conventional technology In the past, painted surfaces generally gave a smooth, slippery, and cold sensation, which was not necessarily desirable in areas where people had visual, tactile, etc. contact, and it was desirable to maintain a warm suede sensation. There were many cases where this was the case. The composition was created with the purpose of obtaining this suede feel.
A method is known in which soft urethane rubber beads are mixed and dispersed in a paint and applied to the target area. However, this method makes the applied surface somewhat more elastic than normal paint,
Although it has the advantage of producing a warm taste, it is far from suede-like and does not satisfy the taste of the sole.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems, and aims to make it possible to maintain a suede feel on the coated surface using the same general application method as before. It is something.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention solves the problems described above.
1 to 20 wt% of short fibers of g1eA to 2.0+++n;
5 to 80 wt% of a solvent for dispersing the short fibers,
Vehicle 3 to 60a+t for attaching short fibers to the target area by one inch
It consists of %.

``Function'' - In the present invention constructed as described above, various urethane resins are selected as vehicles for elongation, softness, adhesion,
Consider light resistance, curing properties, etc., and select a paint that meets the intended performance of the planned paint. For example, acrylic modified urethane resin, polyester modified urethane resin, silicone modified urethane resin, etc. can be selected. In addition to the above-mentioned vehicles and solvents, the paint solvent can be selected from those that dissolve well the resin selected as the vehicle, such as aromatic, aliphatic, ester, and cologne. A drying agent, a color separation prevention agent, a thickening agent, a flattening agent, a sagging prevention agent, an ultraviolet absorber, a hardening agent, etc. can be arbitrarily selected and used as required. Also, short fibers have a length of 0
．． 1 steel II ~ 2.0 mm short fibers 1 ~ 20 w [%], length 0.1. If the length is less than 2.0 mm, it will be difficult to create a suede feel, and if the length exceeds 2.0 mm, the spray gun will clog during paint spraying, which is not preferable.

Moreover, the material of this short fiber can be arbitrarily selected depending on the desired texture, and the thickness can be selected from 0.5 to 3. Q denier can be freely selected, and the fibers can be processed to improve performance, such as light resistance treatment, softening treatment, solvent resistance, and fading resistance.

It is not particularly complicated compared to general paints and can be applied easily.

3. Detailed description of the invention Industrial field of application The present invention relates to a paint that can produce a suede sensation after coating and curing, and is suitable for use in areas where people maintain visual, tactile, etc. contact. Although it can be widely applied, it can be applied to, for example, the interior of a vehicle, the interior walls of a building, the interior and exterior surfaces of an item storage box, etc. to create a suede feel.

Conventional technology In the past, painted surfaces generally gave a smooth, slippery, and cold sensation, which was not necessarily desirable in areas where people had visual, tactile, etc. contact, and it was desirable to maintain a warm suede sensation. There were many cases where this was the case. The composition was created with the purpose of obtaining this suede feel.
A method is known in which soft urethane rubber beads are mixed and dispersed in a paint and applied to the target area. However, this method makes the applied surface somewhat more elastic than normal paint,
Although it has the advantage of producing a warm taste, it is far from the feel of suede and is not satisfactory in terms of texture.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems, and is not conventional. It is intended to make it possible to maintain the suede feel on the coated surface using the same general application means as those described above.

Function: In the present invention configured as described above, a vehicle is selected from among various urethane resins, taking into consideration elongation, softness, adhesion, light resistance, curing properties, etc., and matching the desired planned paint performance. Select. For example, acrylic modified urethane resin, polyester modified urethane resin, silicone modified urethane resin, etc. can be selected. The solvent for the coating material can be selected from those that dissolve well the resin selected as the vehicle, such as aromatic, aliphatic, ester, and ketone solvents. In addition to the vehicle and solvent described above, coloring agents, drying agents, color separation prevention agents, thickeners, flattening agents, sag prevention agents, ultraviolet absorbers, hardening agents, etc. can be arbitrarily selected and used as required. Also, short fibers have a length of 0.1
Use j~20wt% of short fibers with a length of 2.0 mm to 2.0 mm.If the length is less than 0.11 mm, it will be difficult to create a suede feel, and if the length exceeds 2 Os+m, paint spraying will be difficult. This is undesirable as it may clog the spray gun.

In addition, the material of this short fiber can be arbitrarily selected according to the desired texture, and can be freely selected within the range of 0.5 to 3.0 denier, and can be processed into fibers to improve performance, such as Treatments such as light resistance treatment, softening treatment, solvent resistance, and fading resistance can be performed.
