Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an anti-adhesive agent, a polymer composite molded article having the anti-adhesive agent added to the surface thereof, and a method for producing the polymer composite molded article. Particularly, by effectively preventing the anti-adhesive agent from falling off, The present invention relates to an anti-adhesion agent that exhibits a long-term adhesion effect, a polymer composite molded article to which the anti-adhesion agent is added, and a method for producing a polymer composite molded article.

[0002]

2. Description of the Related Art For example, in a polymer molded product mainly composed of a rubber component such as an antivibration material or a thermoplastic elastomer component, the adhesion of the antivibration materials and the adhesion to a contact object contacting the surface thereof are reduced. Therefore, an anti-adhesive agent may be added. That is, in the vibration-proof material, a method of setting the resonance frequency to a low value is used in order to impart a vibration damping property. For that purpose, it is general to lower the hardness or the spring constant of the polymer molded article. It is often the case that a large amount of a softening agent or a plasticizer is added to an object. However, in this case, the adhesion of the surface of the anti-vibration material increases, so it is necessary to prevent adhesion of the anti-vibration material to the chassis or fixing screws to which the anti-vibration material is attached, especially for optical anti-vibration materials. An anti-adhesive agent has been added.

As such an anti-adhesive agent, an inorganic granular substance such as calcium carbonate or talc has been conventionally used. However, the inorganic particulate material has a large hygroscopicity and oil absorption, and sometimes absorbs low-molecular components such as oil mixed with rubber or thermoplastic elastomer. In addition, there is also a problem in that the anti-adhesion effect is not exerted for a long period of time because the particles are granular and thus easily fall off.

Silicone coating materials such as silicone oil or silicone polymer are also used as anti-adhesive agents. However, since the silicone-based coating material is highly likely to be volatilized, there is a concern that electrical contact failure may occur, and the expensive coating material may increase the manufacturing cost.

Further, Japanese Patent Application Laid-Open No. 2001-64445 discloses an anti-adhesive agent made of an organic particulate material having an average particle size of 500 μm or less. However, since this anti-adhesive is also granular, it is likely to fall off, and the anti-adhesive effect may not be exerted for a long time.

Therefore, for example, when the anti-vibration material containing these conventional anti-adhesion agents is used in an optical disk device,
The anti-vibration material may come into close contact with the surface of the chassis and the fixing screw that come into contact with the surface in a short period of time, which may adversely affect the anti-vibration characteristics.

[0007]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention provides an anti-adhesion agent that exhibits an anti-adhesion effect for a long time by effectively preventing the anti-adhesion agent from falling off, and a polymer composite containing the anti-adhesion agent. It is an object of the present invention to provide a method for producing a molded body and a polymer composite molded body.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.

(Anti-Adhesive) The anti-adhesive of the present invention contains whiskers. The anti-adhesive agent containing the whiskers can be added to the surface of the polymer molded article, the inside thereof, or both of them. In particular, when an anti-adhesive agent containing whiskers is added to the surface of a polymer molded product whose main component is a rubber component and / or a thermoplastic elastomer component, the anti-adhesive effect is longer than that of a conventional anti-adhesive agent for surface addition. It became clear that the period would be maintained. It is considered that this is because the whiskers contained in the anti-adhesive agent are needle-like crystals and thus are less likely to roll than the granular substances as in the prior art, and are more likely to be pierced into the polymer molded product.

From the viewpoint that it is possible to more effectively prevent the anti-adhesion agent from falling off, it is preferable that the whiskers contained in the anti-adhesion agent stick to the surface of the polymer molded product. For example, FIG. 1 conceptually shows an example of a state in which the whiskers 1 are stuck into the surface of the polymer molded product 2.

The whiskers contained in the anti-adhesive agent are as follows:
Inorganic whiskers, organic whiskers or both may be used. Examples of the inorganic whiskers include potassium titanate whiskers, silicon carbide whiskers, silicon nitride whiskers, potassium carbonate whiskers, boron carbide whiskers, and zinc oxide whiskers. Examples of organic whiskers include polyoxymethylene whiskers and copolyester whiskers. Preferred is potassium titanate whisker. Potassium titanate whiskers do not change their characteristics even when exposed to a high temperature and high humidity environment, and are inexpensive,
The manufacturing cost can be reduced.

The fiber diameter of the whiskers contained in the anti-adhesion agent is preferably in the range of 0.1 to 10 μm,
More preferably, it is in the range of 0.1 to 1 μm.
The average fiber length of the whiskers is preferably in the range of 10 to 50 μm, more preferably 10 to 20 μm. By including a whisker having such a fiber diameter or an average fiber length in the anti-adhesion agent, it is possible to exert an effective anti-adhesion effect on a low hardness rubber molded article having a durometer hardness of A30 or less.

The anti-adhesive agent of the present invention may contain known anti-adhesive agents such as calcium carbonate and talc in combination with the above whiskers, but the anti-adhesive agent of the present invention comprises only the above whiskers. Is preferably included. In this case, the anti-adhesion agent is less likely to fall off, so that the anti-adhesion effect of the anti-adhesion agent of the present invention continues for a longer period.

(Polymer Molded Product) The polymer molded product used in the present invention is a molded product of a polymer composition containing a rubber component and / or a thermoplastic elastomer component as a main material. Here, the polymer composition includes a rubber composition containing at least one rubber component as a main material, a thermoplastic elastomer composition containing at least one thermoplastic elastomer component as a main material, or a mixture thereof.

The rubber composition which can be used in the present invention is, for example, butyl rubber, natural rubber, butadiene rubber, isoprene rubber, chloroprene rubber, ethylene propylene rubber,
The main component is a rubber component such as styrene-butadiene rubber, styrene-butadiene-styrene rubber, nitrile rubber, polynorbornene rubber, acrylic rubber, urethane rubber, silicone rubber or epichlorohydrin rubber. Above all, it is preferable that the rubber composition contains butyl rubber as a main material. Since this rubber composition has a better vibration and shock absorbing property, it becomes possible to further absorb the vibration and the shock which the polymer composite molded article of the present invention receives from the contact object.

The thermoplastic elastomer composition which can be used in the present invention contains a thermoplastic elastomer component such as a styrene type, an olefin type, an ester type, a polyamide type, a vinyl chloride type or a urethane type as a main component. Among them, the thermoplastic elastomer composition is a styrene-based thermoplastic elastomer component of styrene-ethylene-butylene-styrene block copolymer (SEBS) and / or
Alternatively, it is preferable to use a styrene-ethylene-propylene-styrene block copolymer (SEPS) as a main material. In this case, the weather resistance and heat stability of the polymer composite molded article of the present invention are further improved.

Further, the rubber composition or the thermoplastic elastomer composition may contain other additives. Examples of the additive include a plasticizer, a filler, a cross-linking agent, a vulcanization accelerator, a lubricant or an antioxidant.

Examples of the plasticizer include dimethyl phthalate, diethyl phthalate, di-n-butyl phthalate, di-n-octyl phthalate, di-2-ethylhexyl adipate, di-n-decyl adipate and phosphorus. Tributyl acid,
Examples include tri-2-ethylhexyl phosphate, butyl stearate, process oil, lubricating oil, paraffin, liquid paraffin, petroleum asphalt, vaseline, castor oil, linseed oil, rapeseed oil or coconut oil. The plasticizer is 20 to 100 parts by mass, more preferably 25 to 100 parts by mass with respect to 100 parts by mass of the rubber component and / or the thermoplastic elastomer component.
It is mixed in a ratio of 80 parts by mass. When the amount of the plasticizer is less than 20 parts by mass, it tends to be difficult to obtain a low hardness polymer molded product having a durometer hardness of A30 or less.
When the amount of the plasticizer is more than 100 parts by mass, the plasticizer is likely to bleed from the polymer molded product, and the anti-adhesion effect of the anti-adhesive agent of the present invention tends to be hardly obtained.

Examples of the filler include carbon black, white carbon, calcium carbonate, magnesium carbonate, clay, talc, mica, alumina, barium sulfate or calcium sulfate. The filler is 5 to 100 parts by mass, more preferably 10 to 70 parts by mass with respect to 100 parts by mass of the rubber component and / or the thermoplastic elastomer component.
It is blended in a ratio of 15 parts by mass, more preferably 15 to 50 parts by mass. When the amount of the filler is less than 5 parts by mass, the reinforcing property is not obtained so much, and the mechanical strength of the polymer molded product tends to decrease. When the amount of the filler is more than 100 parts by mass, it becomes difficult to obtain a low hardness polymer molded product having a durometer hardness of A30 or less.

Examples of the cross-linking agent include benzoyl peroxide, dicumyl peroxide and di-t-
Butyl peroxide, t-butyl cumyl peroxide, methyl ethyl ketone peroxide, cumene hydroperoxide, 2,5-dimethyl-2,5-di (t
-Butylperoxy) hexane, 2,5-dimethyl-
Examples include organic peroxides such as 2,5-di (benzoylperoxy) hexane, metal oxides such as zinc oxide and magnesium oxide, and sulfur. Further, as the vulcanization accelerator, for example, sulfenamide-based, thiazole-based, thiuram-based,
There are vulcanization accelerators such as guanidine type or thiourea type. Examples of the lubricant include hydrocarbon-based, fatty acid-based, fatty acid amide-based or ester-based lubricants.

The polymer molded product used in the present invention can be obtained by kneading the above polymer composition by a known method and molding it into a predetermined shape by, for example, compression press molding, preferably transfer molding.

The durometer hardness of the polymer molding used in the present invention is preferably A30 or less, more preferably A10 or less. In this case, the resonance frequency when the polymer molded product of the present invention is used as a vibration isolator can be further lowered, and the vibration isolation region can be further widened. Here, the lower limit of the durometer hardness may be as close as possible to A0. The durometer hardness is a value measured according to JIS-K6253.

The loss factor tan δ of the polymer molded product used in the present invention is preferably 0.2 to 0.8, and more preferably 0.25 to 0.5. When tan δ is less than 0.2, sufficient vibration damping performance tends not to be obtained when the polymer molded product of the present invention is used as a vibration damping material. On the other hand, when the hardness of the polymer molded product is lowered, the value of tan δ generally decreases, but ta
By setting the value of nδ within the above range, it is possible to obtain a polymer molded product having a balance between low hardness and anti-vibration performance.

The compression set of the polymer molded product used in the present invention measured at 70 ° C. for 24 hours according to JIS-K6262 is preferably 5 to 20%, and preferably 5 to 10%. Is more preferable. In this case, for example, even when a product made of the polymer molded product of the present invention is used by being pressure-bonded to a contact object for a long time, the product is less likely to be distorted.

(Production Method of Polymer Composite Molded Article) The polymer composite molded article according to the present invention is produced by a production method including a step of adding the anti-adhesive agent containing the whiskers to the surface of the polymer molded article, the inside thereof, or both of them.

In particular, the method for producing a polymer composite molded article of the present invention preferably includes a step of adding an adhesion preventive agent containing the whisker to the surface of the polymer molded article.

The step of adding the anti-adhesive agent to the surface of the polymer molded article may be carried out by, for example, a method of dusting the anti-adhesive agent on the surface of the polymer molded article or molding the polymer into a solvent in which the anti-adhesive agent is dispersed. It is preferable to carry out the method by immersing the object. When these methods are used, the above-mentioned anti-adhesive agent can be easily added, which leads to a reduction in manufacturing cost. Here, examples of the solvent include water and alcohol.

The step of adding the anti-adhesion agent to the inside of the polymer molded article includes, for example, a method of mixing the anti-adhesion agent in the polymer composition.

The amount of the anti-adhesive agent added to the surface of the polymer molded product is preferably 0.1 to 5 g per 1 m ² of the surface area of the polymer molded product to which the anti-adhesive agent is added. , 0.1 to 3 g is more preferable. The amount of the anti-adhesive agent added to the inside of the polymer molded product is preferably 1 to 10 parts by mass, and 1 to 5 parts by mass with respect to 100 parts by mass of the polymer component.
