Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flame-retardant polyolefin resin composition exhibiting good moldability in calendering and having a smooth film surface and no bloom, and a flame retardant produced using the same. And a flame-retardant pressure-sensitive adhesive tape.

[0002]

2. Description of the Related Art Polyolefin resins are widely used in various fields because they can be produced at low cost and have excellent mechanical and chemical properties. In recent years, vinyl chloride-based resins that may generate dioxin during incineration are being repelled, and thus have attracted attention as an alternative material.

However, the polyolefin resin itself is very flammable, so that a large amount of a flame retardant must be added for use in fields requiring flame retardancy. When a large amount of a flame retardant is added to a polyolefin resin, plate-out of the flame retardant, adhesion to metal, burning, etc. occur, resulting in extremely poor workability. Further, products using the resin composition,
Flame retardant blooms, rough surfaces, etc.
Surface properties tended to be poor.

[0004] Products made of a polyolefin-based resin include sheets, films, and the like. These sheets and films are usually produced by extrusion molding or inflation molding. It is difficult to produce a sheet or a film by calendering using a polyolefin resin as a material, as compared with a vinyl chloride resin, and only a part of the sheet or film has been industrially produced by calendering.

In the calendering process, compared to other molding methods such as extrusion lamination, extrusion stretching, and inflation processing, material change is easy, material loss is small, condition changes during operation are relatively easy, and production speed is low. There are advantages such as very fast. For this reason, it has been excellent in the field of building materials and marking films made of vinyl chloride resin in the past, especially when short-term production of molded products with good color tone reproducibility that requires a small quantity of many types and color variations is required. Met.

However, depending on the type of resin, in calendering, the resin has a low melt tension when the resin sticks to the roll (stickiness), blows out (plate-out), and when the molten film is pulled from the roll. There was a problem that processing could not be performed well.

Attempts have been made to carry out calendering on polyolefin-based resins. However, if a flame retardant is added to the polyolefin-based resin, it becomes impossible to process because the releasability between the resin and the roll is reduced as described above. There were problems that the melt tension of the resin became small, drawdown was easy, and it was difficult to take off from the roll. For this reason, calendering a polyolefin-based resin to which a flame retardant has been added has conventionally been extremely difficult.

[0008]

SUMMARY OF THE INVENTION In view of the above situation, the present invention provides a flame-retardant polyolefin-based resin composition capable of obtaining a molded article of good quality by calendering, and a method of producing the same using the same. It is an object of the present invention to provide a flame-retardant film and a flame-retardant pressure-sensitive adhesive tape.

Hereinafter, the first present invention will be described in detail. The first flame-retardant polyolefin-based resin composition of the present invention comprises a polyolefin-based resin and magnesium hydroxide. The polyolefin resin used in the first present invention has a melt flow rate of 0.11 to 11 g / 10.

FR) is a value measured in accordance with JIS K 7210.

In the polyolefin resin used in the first invention, when the MFR is smaller than the above lower limit, the melt viscosity of the resin is high.
The viscosity further increases, and the resulting resin composition cannot be calendered. Even if calendering can be performed, a film having a smooth surface cannot be obtained. When the MFR of the polyolefin resin is larger than the upper limit, the melt tension of the resin is low,
Although the resulting film has a surface smoothness, the film cannot be stably taken off from the calender roll.

In the first invention, the olefin-based thermoplastic elastomer (hereinafter referred to as TPO) is not particularly limited. For example, a block or graft copolymer having a polypropylene component and an ethylene-propylene copolymer component And a block or graft copolymer having a polybutene component and an ethylene-propylene copolymer component, a polyethylene-ethylenebutylene random copolymer-polyethylene triblock copolymer, an ethylenebutylene random copolymer, and the like. These may be used alone or in combination of two or more. Among them, the TPO includes a block or graft copolymer having a polypropylene component and an ethylene-propylene copolymer component, a polyethylene-ethylenebutylene random copolymer-polyethylene triblock copolymer, and an ethylenebutylene random copolymer. It is preferable that the polymer be made of at least one polymer selected from the group consisting of

PER-T310J, T310E, R410E manufactured by Tokuyama Corporation,

P and the like.

In the first aspect of the present invention, the magnesium hydroxide functions as a flame retardant. The magnesium hydroxide has a surface coated with a higher fatty acid and / or a metal salt thereof. By covering the surface of the magnesium hydroxide with a higher fatty acid and / or a metal salt thereof, the adhesion of the magnesium hydroxide to a metal can be suppressed, and the dispersibility of magnesium hydroxide in a polyolefin resin is improved. Can be done. The higher fatty acid and its metal salt are not particularly limited, and include, for example, stearic acid, oleic acid, magnesium stearate, calcium stearate, magnesium oleate, calcium oleate and the like.

The above magnesium hydroxide does not include those whose surface is untreated and those whose surface is coated with silane. Untreated magnesium hydroxide easily absorbs moisture, easily adheres to metal, and seizes onto rolls during calendering. Therefore, when magnesium hydroxide having an untreated surface is used, magnesium hydroxide baked on a roll is mixed in the film, and it becomes difficult to produce a smooth film. In addition, magnesium hydroxide whose surface is coated with silane has higher adhesion to metal than magnesium hydroxide whose surface is untreated, so that calendering of the obtained resin composition becomes difficult.

The average particle diameter of the magnesium hydroxide coated on the surface with the higher fatty acid and / or its metal salt used in the first invention is 0.6 to 3.5 μm. When the average particle diameter exceeds 3.5 μm, the film surface becomes rough or the surface area of magnesium hydroxide decreases, so that the flame retardancy decreases. Preferably, 0.6-1.
0 μm.

The flame-retardant polyolefin resin composition of the first invention comprises 100 parts by weight of the polyolefin resin,
And 50 to 300 parts by weight of the magnesium hydroxide. If the amount of the magnesium hydroxide is less than 50 parts by weight, the obtained resin composition does not have sufficient flame retardancy. If it exceeds 300 parts by weight, the viscosity of the obtained resin composition becomes too large, which affects the processability, and the surface smoothness of a film produced using the resin composition is lost. Preferably, 100 to 200
Parts by weight.

The flame-retardant polyolefin-based resin composition of the first invention may use, in addition to the above-mentioned magnesium hydroxide, an ammonium polyphosphate whose surface is coated with a thermosetting resin as a flame retardant. .

Hereinafter, the second present invention will be described in detail. The ammonium polyphosphate used in the second present invention has a surface coated with a thermosetting resin and functions as a flame retardant. The ammonium polyphosphate,
By covering the surface with a thermosetting resin, adhesion to metal is suppressed. The thermosetting resin is not particularly limited, and examples thereof include a melamine resin, a phenol resin, an epoxy resin, a urethane resin, and a urea resin.

The above-mentioned ammonium polyphosphate does not include ammonium polyphosphate whose surface is untreated. Since the untreated ammonium polyphosphate easily adheres to the metal and sticks to the roll during calendering, if the untreated ammonium polyphosphate is used, the ammonium polyphosphate baked to the roll will be mixed in the film. Also, since the bloom of ammonium polyphosphate on the film surface is severe, it is difficult to produce a smooth film.

The average particle diameter of the ammonium polyphosphate coated on the surface with the above-mentioned thermosetting resin used in the second invention is 5 to 25 μm. The average particle size is 25
If it exceeds μm, the surface of the film may be roughened. Preferably, it is 5 to 10 μm.

The flame-retardant polyolefin-based resin composition of the second invention comprises 100 parts by weight of the above-mentioned polyolefin-based resin,
And 10 to 100 parts by weight of the above ammonium polyphosphate. When the amount of the ammonium polyphosphate added is 10
When the amount is less than part by weight, the obtained resin composition does not have sufficient flame retardancy. If it exceeds 100 parts by weight, the viscosity of the obtained resin composition becomes too large, which affects the processability, and the surface smoothness of a film produced using the resin composition is lost. Preferably, it is 20 to 80 parts by weight.

The flame-retardant polyolefin resin composition of the second invention comprises, as a flame retardant, magnesium hydroxide whose surface is coated with the above-mentioned higher fatty acid and / or a metal salt thereof in addition to the above-mentioned ammonium polyphosphate. You may use together.

Hereinafter, the flame-retardant polyolefin-based resin composition of the first invention and the flame-retardant polyolefin-based resin composition of the second invention will be further described. The flame-retardant polyolefin-based resin composition of the present invention, in addition to the polyolefin-based resin and the flame-retardant, if necessary, a flame-retardant auxiliary,
Polyhydric alcohols, metal oxides, fatty acid esters, nitrogen compounds, metal soaps and the like may be added as processability improving aids, and 1 to 50 parts by weight are preferably added to 100 parts by weight of the polyolefin resin. preferable. By adding the flame retardant aid and the processability improving aid, the flame retardancy and processability of the obtained resin composition are improved, and the surface smoothness of a film produced using this resin composition is also improved. . When the addition amount of the above-mentioned flame retardant auxiliary agent and processability improving auxiliary agent exceeds 50 parts by weight, the mechanical properties of the obtained resin composition deteriorate.

The flame-retardant polyolefin resin composition of the present invention may optionally contain known additives such as antioxidants, ultraviolet absorbers, lubricants, pigments and the like, which are generally added to resins. You may.

The flame-retardant polyolefin-based resin composition of the present invention can be obtained by appropriately mixing the above-mentioned components in predetermined amounts and mixing them uniformly using a Banbury mixer or the like according to a conventionally known method. .

Since the flame-retardant polyolefin-based resin composition of the present invention has the above-mentioned constitution, it is difficult for the flame-retardant to adhere to the roll during calendering. The flame-retardant polyolefin resin composition of the present invention can be formed into various shapes such as sheets and films by calendering. Among them, the flame-retardant polyolefin-based resin composition of the present invention can be suitably used as a material for a film. A flame-retardant film formed by calendering the flame-retardant polyolefin-based resin composition of the present invention is also one of the present invention.

The flame-retardant polyolefin resin composition of the present invention can be stretched thinly by calendering, and has a thickness of 500 μm or less, and a thickness of 60 μm or less.
It can be formed into a thin film of about μm. The thickness of the flame retardant film of the present invention is preferably 500 μm or less. More preferably, the thickness is 60-300μ
m. The flame retardant film of the present invention has a thickness of 60 μm
Even if it is thin, the surface is smooth and there is almost no bloom of the flame retardant.

By subjecting the flame-retardant film of the present invention to an adhesive treatment, a flame-retardant adhesive tape can be produced. The flame-retardant pressure-sensitive adhesive tape is also one of the present invention.

Since the flame-retardant polyolefin resin composition of the present invention has the above-mentioned constitution, it is excellent in both flame retardancy, which has been difficult to achieve compatibility in the past, and moldability in calendering, and is obtained. The product has a smooth surface and no flame retardant bloom. Further, since the flame retardant polyolefin resin composition of the present invention does not contain halogen in the flame retardant, it hardly generates halogen-based gas or toxic gas.
