Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a vinyl chloride resin molded article. More specifically, the present invention relates to a vinyl chloride resin molded product which prevents migration of the surface of a plasticizer or the like, prevents contamination of the molded product surface, and has excellent water resistance and durability.

[0002]

2. Description of the Related Art Vinyl chloride resins are relatively inexpensive and are less likely to undergo chemical changes, and their properties can be varied over a wide range from hard to soft by blending plasticizers in varying amounts. For example, there are many uses for both hard and soft materials such as hard pipes, floor materials, sheets, films, soft vinyl cloths, fibers, wall materials, sheets, films, and daily necessities. However, with vinyl chloride resin molded products containing a plasticizer, after a long period of time, the plasticizer bleeds out to the surface of the molded product, migrates to other substances, or is extracted into water or solvents. Therefore, there is a disadvantage that an undesirable phenomenon is exhibited. For example, when a soft vinyl chloride resin molded product comes into contact with the housing of an electric product such as a television, a video deck, or a personal computer made of a styrene resin such as ABS resin, impact-resistant polystyrene or general-purpose polystyrene, a plasticizer contacts the housing. Will migrate. Due to this transition, the housing may be stained or cracked, thereby impairing the aesthetic appearance, significantly lowering the commercial value and, in some cases, deteriorating the function.

When a molded article made of a vinyl chloride resin is used outdoors such as an interior material such as a floor material and a wall material and a tent, a plasticizer bleed out to the surface of the molded article is used. However, there is a drawback that dust adheres and is contaminated. When the molded article is a film used for packaging, the bleed-out plasticizer lowers the printability on the film or lowers the strength of the portion bonded by the heat sealing method. Furthermore, when the molded article is used for applications requiring water resistance, such as a waterproof canvas tent, a simple water tank, a water stoppage plate, a waterproof sheet, etc., the plasticizer flows away due to the influence of rainwater, and the molded article becomes white. Problems such as cracking, brittleness, and damage occur.

As a method for solving these problems, the following method has been proposed in which the surface of a vinyl chloride resin molded article is coated with a specific resin or paint. (I) A method of applying an acrylic resin (JP-B-46-2)
9639, JP-B-50-28117, etc.) (ii) A method of applying a fluororesin via an adhesive layer (JP-A-56-86748, JP-A-57-8155, JP-A-57-8155) (Iii) A method of applying a mixture of a fluororesin and an acrylic resin (JP-A-63-21143, JP-A-64-6)
No. 5161, Japanese Patent Publication No. 63-236)

However, (i) is not enough to prevent the bleed out of the plasticizer or the like of the base material to the surface of the molded article, and (ii) is due to the effect of the plasticizer or the like migrating to the adhesive layer. ,
The adhesion and integration of the fluororesin and the substrate through the adhesive layer was not practically sufficient. Although (iii) has been proposed as these improvements, the interface adhesion between the base material and the fluororesin mixture is insufficient, and the acrylic resin and the fluororesin are hardly dissolved, so that the coating film becomes opaque. There were drawbacks.

[0006]

Under such circumstances, the present inventors have prevented various additives, particularly plasticizers, incorporated into a vinyl chloride-based resin molded product from migrating to the surface, and contaminated the surface of the molded product. In order to provide a molded article of a vinyl chloride resin having excellent water resistance and its durability, and having good transparency, the present inventors have conducted intensive studies and, as a result, have completed the present invention. .

[0007]

It is a vinyl chloride resin molded article formed by forming a coating of a composition comprising a fluorinated acrylic resin [B] comprising a copolymer of about 60% by weight.

Examples of the monomer compound copolymerizable with vinyl chloride include vinylidene chloride, ethylene, propylene, acrylonitrile, maleic acid, itaconic acid, acrylic acid, methacrylic acid, and vinyl acetate. These vinyl chloride resins may be produced by any of conventionally known production methods such as an emulsion polymerization method, a suspension polymerization method, a solution polymerization method, and a bulk polymerization method. In order to impart flexibility to the vinyl chloride-based resin serving as the base, 1 part by weight or more, preferably 20 parts by weight, per 100 parts by weight of the resin is used.
６０60 parts by weight of a plasticizer is blended. By setting the blending amount of the plasticizer within the above range, the desired vinyl chloride molded article can be imparted with excellent flexibility and mechanical properties.

Examples of the plasticizer include phthalic acid derivatives such as di-n-octyl phthalate, di-2-ethylhexyl phthalate, dibenzyl phthalate, diisodecyl phthalate, didodecyl phthalate and diundecyl phthalate; and isophthalic acids such as dioctyl phthalate Derivatives; adipic acid derivatives such as di-n-butyl adipate and dioctyl adipate; maleic acid derivatives such as di-n-butyl malate; citric acid derivatives such as tri-n-butyl citrate; itaconic acid derivatives such as monobutyl itaconate Oleic acid derivatives such as butyl oleate; ricinoleic acid derivatives such as glycerin monoricinoleate; and other epoxidized soybean oils and epoxy resin plasticizers.

The amount of the various resin additives to be added can be selected within a range that does not deteriorate the properties of the film, and usually within a range of 10 parts by weight or less based on 100 parts by weight of the vinyl chloride resin as the substrate.

However, in order to mix other known resin additives including a plasticizer to form a vinyl chloride-based resin compounding composition for molding, a usual compounding and mixing technique such as a ribbon blender, a Banbury mixer, A method using a super mixer or other compounding machine or mixer can be adopted. There is no particular limitation on the shape of the vinyl chloride-based resin-blended composition formed into the vinyl chloride-based resin molded article of the present invention. However, a sheet-like, film-like, plate-like, or tubular form is suitable because of the ease of the process of forming a film. As these molding methods, usually,
