DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a awning tent,
Olefin resin molded products suitable for automotive seats, flexible container seats, house tents, etc.
More specifically, the present invention relates to an olefin resin molded article which can be fused by a high-frequency induction heating treatment (a high-frequency welder treatment) and has excellent heat-resistant creep characteristics.

[0002]

2. Description of the Related Art Hitherto, as a material for a awning tent, a sheet for a flexible container, and the like, a polyvinyl chloride resin molded article having excellent flexibility and secondary workability has been used. However, polyvinyl chloride resin molded articles have problems such as the generation of chlorine-containing gas when incinerated and disposed, and the plasticizer contained in the molded articles may leach out when landfilled. doing. For this reason,
For the above applications, development of materials containing no halogen has been desired from the viewpoint of environmental conservation.

For example, Japanese Utility Model Registration No. 3022036 discloses an olefin laminated sheet in which a cloth-like or net-like sheet and a polyolefin sheet are laminated via an amorphous polyalphaolefin. However, since polyolefins and amorphous polyalphaolefins have low heat build-up due to high-frequency induction treatment, fusion by high-frequency welding is not possible with this method, and amorphous polyalphaolefin used for the adhesive layer is not used. However, the heat-resistant creep characteristics of the resulting laminate sheet were insufficient due to the poor heat resistance of the resulting laminate sheet.

Japanese Patent Application Laid-Open No. 7-137203 discloses an olefin-based thermoplastic elastomer as an intermediate layer in order to improve the high-frequency fusing property of an olefin-based resin, on both surfaces of which a radical polymerizable acid anhydride such as ethylene and maleic anhydride is formed. Discloses a three-layer film formed by coating with a multi-component copolymer resin of a product monomer and a radical polymerizable comonomer such as vinyl acetate. Although the high-frequency fusion property of this laminated film is improved, the adhesive strength between the layers is low, so that the heat creep resistance is insufficient as a whole, and the outermost layer is formed of a multi-component copolymer resin. The solvent resistance characteristic of olefin-based elastomers,
In addition, it has a drawback that the antifouling property is not exhibited.

As a method for imparting flame retardancy to an olefin resin molded article, for example, Japanese Patent Application Laid-Open No. Hei 4-253745 discloses an inorganic resin such as aluminum hydroxide or magnesium hydroxide per 100 parts by weight of olefin resin. 50 to 300 parts by weight of flame retardant, glassy inorganic powder 10 to 100
A method of adding parts by weight is disclosed. However, in this method, since the inorganic filler is added in a large amount, the mechanical strength of the obtained resin composition is extremely low, and the sheet-like molded article formed therefrom has no fusibility due to high-frequency welding. Therefore, high frequency sewing was impossible.

BEST MODE FOR CARRYING OUT THE INVENTION The fibrous base fabric used in the olefin resin molded article of the present invention includes natural fibers such as cotton and hemp, inorganic fibers such as glass fiber and carbon fiber, and the like.
Regenerated fiber such as metal fiber, for example, viscose rayon,
Semi-synthetic fibers, such as cupra, synthetic fibers, such as gee and triacetate fibers, such as nylon 6, nylon 66, polyester (such as polyethylene terephthalate) fibers, aromatic polyamide fibers, acrylic fibers, olefin fibers, etc., and water insolubilization Alternatively, a cloth made of at least one selected from, for example, insoluble polyvinyl alcohol fibers can be used.

The fibers in the base fabric may be formed into any shape such as a spun short fiber yarn, a long fiber yarn, a split yarn or a tape yarn, and the base fabric may be a woven fabric, a knitted fabric or a composite thereof. Any of these may be used. There is no particular limitation on the knitting structure of the base fabric, but, for example, at least a coarse knitted woven fabric and a non-coarse knitting constituted by yarns including a warp and a weft arranged in parallel with a gap between yarns. The fabric can be selected from a woven fabric (a knitted fabric in which substantially no gap is formed between the yarns).

The basis weight of the coarse knitted fabric is preferably 30 to 700 g / m ² , and the light transmission area ratio of the coarse knitted fabric is
It is preferably about 10 to 95% of the area of the coarse knitted fabric. When the fibrous base fabric is a non-coarse knitted fabric, its structure, basis weight, thickness, etc. are not limited, but depending on the intended use of the olefin resin molded article, plain weave, twill weave, circular knit, and warp knit. And the like, and the basis weight is preferably about 50 to 1000 g / m ² .

The olefin resin used in the olefin resin layer of the olefin resin molded article of the present invention includes:
Homopolymers such as polyethylene, polypropylene, polybutene-1, poly-4-methylpentene-1 and the like are mixed or alloyed with a homopolymer and an olefin rubber, for example, ethylene-propylene rubber in the composition. Resins, and copolymers of ethylene and other monomers, for example, ethylene-α-olefin copolymer, ethylene-vinyl acetate copolymer, ethylene-
At least one selected from (meth) acrylic acid copolymer and the like is used. Here, the ethylene- (meth) acrylic acid copolymer is a general term for a copolymer of ethylene-acrylic acid and ethylene-methacrylic acid. Especially,
In order to obtain molded products with high cold resistance, stain resistance and flexibility,
As the olefin resin, it is preferable to use an ethylene-α-olefin copolymer, an ethylene-vinyl acetate copolymer, and an ethylene- (meth) acrylic acid copolymer.

Among them, the ethylene-α-olefin copolymer has a small dielectric loss, so that it has been conventionally impossible to fuse by high frequency, but in the molded article of the present invention, the fusion is performed. It becomes possible. In the ethylene-α-olefin copolymer used in the present invention, the α-olefin copolymerized with ethylene has 3 to 18 carbon atoms.
Α-olefins such as propylene and butene
At least one selected from 1,4-methylpentene-1, hexene-1, octene-1, decene-1 and the like is used. The copolymerization ratio of the α-olefin in this copolymer is preferably from 8 to 25% by weight. If it is less than 8% by weight, the resulting molded article may have insufficient cold resistance and flexibility, and if it exceeds 25% by weight, the resulting molded article may have insufficient heat resistance. In some cases, there is a disadvantage that blocking occurs on the surface of the molded article.

Also, an ethylene-vinyl acetate copolymer,
Ethylene- (meth) acrylic acid-based copolymers have increased heat generation by high-frequency induction treatment (high-frequency welder treatment) in accordance with an increase in the ratio of monomers copolymerized with ethylene, which enables high-frequency fusion. Where
Increasing the proportion of the comonomer lowers the heat resistance of the resin and results in lower heat creep resistance. In particular, in applications such as sunshades and flexible containers, the sewability by high-frequency fusion is one of the important characteristics, and for this reason, the high-frequency induction heat build-up of the copolymer resin obtained by increasing the polymerization ratio of the copolymerizable monomer. However, at present, it is possible to reduce the resin strength and the heat creep resistance. On the other hand, according to the present invention, even if a resin having a low copolymerizable monomer ratio having excellent resin strength and heat-resistant creep properties is used for the olefin-based resin layer, high-frequency fusion is possible, and sufficient sewing strength is obtained. It is possible to obtain the molded article shown.

In the ethylene-vinyl acetate copolymer used in the present invention, the content of the vinyl acetate component is 2-3.
It is preferably 0% by weight, and more preferably 3 to 20% by weight. If the content of the vinyl acetate component is less than 2% by weight, the flexibility of the obtained molded article may be insufficient, and if it exceeds 30% by weight, the resin strength and heat creep resistance of the obtained copolymer will be insufficient. May be insufficient.

The ethylene- (meth) acrylic acid copolymer used in the present invention includes an ethylene-methyl (meth) acrylate copolymer and an ethylene-ethyl (meth) acrylate copolymer. Content of (meth) acrylic acid component in these copolymers is 2 to 2
The content is preferably 5% by weight, more preferably 3 to 15% by weight. If the content of the (meth) acrylic acid component is less than 2% by weight, the flexibility of the obtained molded article may be insufficient, and if it exceeds 25% by weight,
The resin strength and heat creep resistance of the obtained copolymer may be insufficient.

Coalesce, and by further containing at least one terpolymer selected from ethylene-vinyl acetate-carbon monoxide copolymer, without impairing the resin strength of the olefin resin, and heat creep resistance. It is possible to further increase the high-frequency induction heat build-up, and it is also possible to highly disperse and highly fill various additives, particularly inorganic fillers added for the purpose of imparting flame retardancy. . In the ethylene-acrylate-carbon monoxide copolymer, ethylene-methacrylate-carbon monoxide copolymer, and ethylene-vinyl acetate-carbon monoxide copolymer used in the present invention, ethylene is used. Component content is 60 to 7
Preferably, the content is 0% by weight, the content of the (meth) acrylate or vinyl acetate component is 20 to 35% by weight, and the content of the carbon monoxide component is 5 to 15% by weight. The addition amount of the terpolymer to the olefin resin is preferably 1 to 40 parts by weight,
More preferably, it is 30 parts by weight. When the addition amount of the terpolymer is less than 1% by weight, the effect of enhancing the high-frequency induction heat build-up, the dispersibility of the flame retardant imparting agent, and the effect of improving the high filling property may be insufficient. If it exceeds 40% by weight, the heat resistance and the heat creep resistance of the obtained olefin resin layer may be impaired.

When the terpolymer is not used in combination with the olefin resin layer, the addition amount of the flame retardant is preferably 40 to 120 parts by weight based on 100 parts by weight of the olefin resin. If the amount of the flame retardant is less than 40 parts by weight, sufficient flame retardancy may not be obtained.
If the amount is more than 10 parts by weight, the resin strength of the obtained olefin-based resin layer may be significantly reduced, and the heat creep resistance may be impaired. Further, when the terpolymer is used in combination, a molded article having higher flame retardancy can be obtained as compared with the case where the terpolymer is not used in combination. In this case, the addition amount of the flame retardant is preferably 40 to 350 parts by weight based on 100 parts by weight of the total amount of the olefin resin and the terpolymer. If it is less than 40 parts by weight, it may not be possible to obtain sufficient flame retardancy. If it exceeds 350 parts by weight, the resin strength of the obtained olefin-based resin layer is greatly reduced, and the heat creep resistance is poor. May be impaired.
