Abstract

PURPOSE:To facilitate formation of a paint film having a pile raising layer, by a method wherein lacquer system paint in which a given amount of piles having a given size are added and mixed is coated by spray on the inner surface of a box for an automobile, e.g. a console box, a globe box. CONSTITUTION:When a paint film 5 having a fabriclike paint surface (a pile raising layer 7) is formed on the inner surface of a box body 1, e.g. a console box, in prior to formation of the pain film 5, degreasing treatment is applied on the inner surface of the box body 1 by means of alcohol. In case the material of the body 1 is a non-polar material, e.g. PP, polarizing treatment or primer treatment is previously applied on the inner surface thereof. Lacquer system paint of 10-60wt.% a resin content in which 5-15wt.% piles having a size of 0.5-2.0denier and a length of 0.2-0.5mm is added and mixed is painted by spray, and thereafter heating and dry processing is applied to form a desired paint film 5.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to automobile boxes such as console boxes and glove boxes whose inner surfaces are finished in a fabritta style.

<Prior Art> Conventionally, the inner surface of an automobile box body has been sometimes finished in a fabritta style from the standpoint of improving design and tactility.

The mainstream method for finishing the inner surface of an automobile box body in a fabric-like manner has generally been to use electrostatic flocking.

<Problems to be solved by the invention> However, equipment for electrostatic flocking is expensive and has a large initial cost, making it unsuitable for high-mix, low-volume production in response to the recent demand for diversified designs for automobile boxes. there were. Furthermore, because the high-voltage electrostatic field of electrostatic flocking is directional, a uniform flocking surface (fabric surface) is created on the inside of the box body.
was difficult to form.

Furthermore, in electrostatic flocking, only the ends of the pile were bonded to the adhesive layer, so the adhesive force was weak. Therefore, when the car is running or stopping, it frequently comes into contact with the items placed inside the box body.Even if the pile is electrostatically flocked on the inside of the box body, the pile is likely to fall off when it comes into contact with the items, and it will last for a long time. It was difficult to maintain the fabris-like appearance of the inner surface of the box body.

Means for Solving the Problems> In order to solve the above problems, the present inventors made extensive efforts in development, and as a result, came up with an automobile box having the following configuration.

A resin content of 10 to 60 weight % is added and mixed to the inner surface of the car box body with 5 to 15 weight % of pile having a thickness of o, 5 to 2゜0 denier (D), and a length of 0.2 to 0.5 am. %
An automobile box, characterized in that a coating film having a raised pile layer is formed by spray application using a lacquer-based paint.

<Embodiments> In order to better understand the present invention, embodiments of the present invention will be described below based on FIGS. 1 and 2.

Spray coat the inner surface of the box body 1 with a paint with the composition shown below to make it look fabritta-like (pile-raised layer 7).
) is formed.

Here, examples of the molding material for the box body 1 include ABS resin, polypropylene (PP), polyvinyl chloride, etc., and molding methods include injection molding, transfer molding, blow molding, compression molding, and extrusion molding. etc., but not particularly limited. Furthermore, the one-spray method may be an air or airless method, but an air method is preferable from the standpoint of napping properties.

It goes without saying that the inner surface of the box body 1 must be degreased with alcohol or the like prior to forming the coating film 5. Furthermore, if the material of the box body 1 is a non-polar material such as PP, it is necessary to polarize the inner surface with plasma or the like or apply brimer coating in advance.

Paint composition: Lacquer-based paint with a resin content of 10 to 60 wt%, and 0
．． Added 5 to 15 wt% of pile with a denier of 5 to 2.0 and a length of 0.2 to 0.5 mm.

In the above, if the resin content is less than 10 wt%, problems tend to occur in the bonding properties of the pile to the coating 1II5.

In addition, if the resin content exceeds 60 wt%, the pile will
This is undesirable because it is easy to get buried in the pile, and the protrusion length of the pile from the five surfaces of the coating film becomes small, which reduces bulkiness, which is a factor that increases the feeling of fabris.

The resin component is usually urethane-based or acrylic urethane-based, but is not limited to these as long as it has good adhesion to the box body 1.

For example, the urethane resin component may be a one-component type such as an oil-modified type, a moisture-cured type, a block type, or a two-component type such as a catalyst-cured type or a polyol-cured type, but from the viewpoint of coating film performance (
The inner surface of automobile boxes is required to have wear resistance, scratch resistance, etc. ), a polyol-cured type is preferable.

Pigments and other auxiliary materials may be mixed with this resin component, if necessary.

Further, as the volatile solvent constituting the lacquer, thinner used in ordinary lacquer paints is used.

If the pile thickness and length are smaller than the above values, the uprightness of the pile from the coating surface will be weak, and the length of the pile protruding from the coating surface will be small, resulting in an increase in the feeling of fabris, as described above. If it is thicker than the above-mentioned value, which is undesirable because it reduces bulkiness, which is an element, the spray gun is likely to clog, making spray application difficult.

In addition, if the amount of pile added is less than 5 wt%, the pile density on the inner surface of the box body 1 will be coarse and it will be difficult to give a fabrit texture, and if it exceeds 15 wt%, the spray gun will be easily clogged and spray painting will be difficult. becomes.

The pile i[ is made of polyester, rayon, or nylon fibers, and is preferably made of nylon fibers from the viewpoint of dispersibility and adhesion.

Note that after the above-mentioned spray coating, it may be dried at room temperature, but from the viewpoint of productivity, it is usually heat-dried for 60 to 0.5 h depending on the heat-resistant temperature of the box body 1. Let's do it.

<Example> (1) The inner surface of the console box body 1 made of ABS,
After degreasing with isopropyl alcohol, the resin content is 1
6 nylon fiber piles (thickness, 1.OD, length;
A mixture of 9 wt % of 0.3 ml11) was applied using a spray gun. Thereafter, drying was performed at 80° C. for 30 minutes.

(2) After degreasing the inner surface of the ABS console box body in the same way as in (1) above, apply 6 nylon fiber piles (thickness, 1.5D , length; 0.4Il1m) to 11
The wt% added mixture was applied with a spray gun. Thereafter, drying was performed at 70° C. for 30 minutes.

The inner surfaces of the console box main bodies 1 manufactured as described in (1) and (2) above all had a fabric feel with a high design quality and were soft to the touch.

<Operations and Effects of the Invention> As described above, the automobile box of the present invention has a dog shape of 0.5 to 2.0 denier and a length of 0 on the inner surface of the box body.
．． A lacquer-based paint with a resin content of 10 to 60% by weight, which is mixed with 5 to 15% by weight of pile of 2 to 0.5 IIIm.
By forming a coating film having a raised layer by spray coating, the following effects are achieved.

In order to finish the inside of the box body in a fabritta style,
The car box of the present invention does not require the use of an electrostatic flocking device that has a high initial cost as in the past, and only requires simple painting. It is suitable for production of various types in small quantities.

Further, unlike electrostatic flocking, there is no need to consider the directionality of the electric field, and a uniform fabric surface can be easily formed on the inner surface of the box body.

Furthermore, since the pile is mixed with the lacquer paint and applied, the adhesive area between the pile and the paint becomes large, making it difficult for the pile to fall off. Therefore, even on the inner surface of the box, which frequently comes into contact with the articles placed in the box, the fabric feeling can be maintained for a long period of time.
