DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silicone emulsion composition for mold release, and more particularly to an addition reaction type silicone emulsion composition for mold release which is advantageous not only in safety and health but also in environmental measures.

[0002]

2. Description of the Related Art Conventionally, a silicone composition for releasing has been used to prevent sticking or sticking between a substrate such as paper and a plastic film and a tacky substance. At present, the main component of the silicone composition for mold release is provided in the form of an organic solvent solution and is widely used.

[0003] However, this type of organic solvent solution type is mainly composed of a raw rubber-like organopolysiloxane having a high molecular weight which is difficult to handle and uses a large amount of solvent, which causes air pollution. In addition, there is a disadvantage that it is not preferable in terms of safety and health. In order to cope with such a drawback, it is conceivable to recover the solvent at the time of using the silicone composition for release, but there is a drawback that a large investment is required to install a recovery device.

[0004] A solvent-free type silicone composition for release which does not use any solvent is also known, but it is necessary to renew the equipment because the coating equipment currently used cannot be applied. In addition, there is a drawback that advanced technology is required for uniform thin film coating. Emulsion-type silicone compositions for mold release are known as being able to solve such disadvantages. In this case, as a curing type of the silicone composition, a condensation reaction type and an addition reaction type are known.

Of these, the condensation reaction type has been used for a long time as in the case of the organic solvent type, but has the disadvantage that the pot life is extremely short, and is used only for very special applications. ing. The addition reaction type is disclosed in JP-B-57-53143 and JP-A-54-53143.
No. 52160 and Japanese Patent Publication No. 6-47624.

The emulsion disclosed in Japanese Patent Publication No. 57-53143 is an emulsion comprising an organovinylpolysiloxane, a platinum compound, an emulsifier and water, and
An emulsion comprising an organohydrogenpolysiloxane, an emulsifier, and water is produced, and the two types of emulsions are mixed to produce a silicone composition for mold release. It has the disadvantage of being slow.

The emulsion disclosed in Japanese Patent Application Laid-Open No. 54-52160 is for producing a release paper composition by an emulsion polymerization method. However, the properties obtained by this method are still inferior to those of the mechanical emulsification method, and the peeling force is relatively poor.

On the other hand, in the case of the emulsion described in Japanese Patent Publication No. 6-47624, an emulsion composed of an organovinylpolysiloxane, an organohydrogenpolysiloxane, an emulsifier and water, or a mixture of a platinum compound and an emulsifier is used. It is characterized by using a self-emulsifying type catalyst, and the release silicone composition produced by the present method has excellent stability and excellent releasability.

However, the catalyst used in this case is of a two-pack type, and must be stirred before use to emulsify itself, and the usable time is short. Furthermore, in this case, since the composition is a three-part composition as a whole, there is a drawback that the dispersibility of the catalyst in the main emulsion greatly affects the properties of the obtained composition. Further, in general, a mixture of a platinum compound and an emulsifier has a disadvantage that the catalytic ability decreases with time.

[0010]

The inventors of the present invention have conducted intensive studies on a release silicone emulsion composition having good storage stability and excellent curability, releasability, and residual adhesiveness. By using a specific thing as an organovinylpolysiloxane, an organohydrogenpolysiloxane, a surfactant, a catalyst, etc., and using an emulsion of a platinum-based catalyst using a specific emulsifier as a catalyst for a silicone emulsion, The inventors have found that the disadvantages can be overcome and arrived at the present invention.
Therefore, an object of the present invention is to provide an addition-reaction-type separation that is excellent in curability, peelability and residual adhesiveness, and is excellent in safety and hygiene and environmental measures in spite of being easy to use with two components. It is to provide a silicone emulsion composition for molds.

[0011]

SUMMARY OF THE INVENTION The above objects of the present invention are as follows.
The composition comprises: a composition A containing the following components and a composition B containing the components;
And the composition B was used in such a manner that the components were mixed at 0.5 to 5 parts by weight with respect to 100 parts by weight of the components.

(Composition A) 100 parts by weight of an organopolysiloxane represented by the following formula:

Embedded image ( Wherein , R ¹ may be the same or different and is a monovalent hydrocarbon group containing no aliphatic unsaturated bond; R ² is a monovalent hydrocarbon group containing no hydrogen atom or aliphatic unsaturated bond. Hydrogen groups, d and e are 20 to 9 of all groups directly bonded to a silicon atom.
5 mol% is a hydrogen group and has a viscosity at 25 ° C. of 5
Shows an integer of up to 200 cs. ) HLB is 10-1
5. 1 to 10 parts by weight of a nonionic surfactant having a pH of 6.5 or less and an ion conductivity of 30 μMho / cm or less, 80 to 230 parts by weight of water;

(Composition B) 100 parts by weight of a polysiloxane containing a platinum complex having a viscosity at 25 ° C. of 10 to 500 cs, an HLB of 10 to 15, a pH of 6.5 or less, and an ionic conductivity of 30 μmho / cm or less 10 to 100 parts by weight of a nonionic surfactant, and 300 to 390 parts by weight of water.

Part of the first component of the composition A can be replaced with an organopolysiloxane represented by the following formula (6).

Embedded image (Wherein, R ^{1 s} may be the same or different and each is a monovalent hydrocarbon group containing no aliphatic unsaturated bond;
^At least 80 mol% of ¹ is a methyl group, and a is 25
The integer at which the viscosity at 25 ° C is 25 to 2,000 cs is shown. )

In the organopolysiloxane represented by the chemical formula 6, both ends of the molecular chain are blocked with dimethylvinylsilyl groups. The substituent R ¹ is a monovalent hydrocarbon group containing no aliphatic unsaturated bond, and specific examples thereof include an alkyl group such as a methyl group, an ethyl group, a propyl group and a butyl group, a phenyl group, a tolyl group. Aryl or cycloalkyl such as cyclohexyl, or monovalent carbon in which some or all of the hydrogen atoms bonded to carbons of these groups have been substituted with halogens, cyano, alkoxy, etc. And a hydrogen group.

The substituents R ¹ may be the same or different, but R ¹ and the integer a are all R
80% or more of ¹ is a methyl group, and the viscosity at 25 ° C. is selected to be 25 to 2,000 cs.
A that satisfies this condition is an integer in the range of approximately 10 to 300.

The organopolysiloxane represented by Chemical Formula 4 has both ends of a molecular chain blocked by a dimethylvinylsilyl group and has a vinyl group in a side chain.
The substituent R ¹ is a monovalent hydrocarbon group containing no aliphatic unsaturated bond as in the case of the substituent R ¹ in Chemical formula 6 , and specific examples thereof include the same as those in R ¹ in Chemical formula 6. Exactly the same can be mentioned.

The substituents R ¹ may be the same or different, but R ¹ and the integers b and c are 1 to 1 of all organic groups.
0 mol% is a vinyl group, and the viscosity at 25 ° C is selected to be 30 to 10,000 cs. B + c that satisfies this condition is an integer in the range of approximately 20 to 600, preferably an integer of 50 to 300, and c is 1
Is an integer of 〜60.

The organopolysiloxane represented by the chemical formula 4 has a vinyl group at both ends and also has a vinyl group in a side chain. The adhesion rate is good, and it does not adversely affect the substance to be adhered. Furthermore, surprisingly, it has been found that when this organopolysiloxane is emulsified in water with a surfactant together with the second component, organohydrogenpolysiloxane, the stability of the emulsion is excellent.

The viscosity at 25 ° C. is 10,000 cs.
When it exceeds, when an emulsion is prepared by using a generally known emulsification technique, the emulsion is easily separated into two layers and the stability is lowered, which is not preferable. When the content of the vinyl group of the organopolysiloxane represented by Chemical Formula 4 is less than 1 mol%, the curability is poor, and when it exceeds 10 mol%, the peeling power becomes unstable.

As the second component of the composition A, an organohydrogenpolysiloxane having at least three hydrogen atoms directly connected to a silicon atom in one molecule represented by the above formula (5) is used.

Is 0, the stability of the emulsion obtained when the first component and the second component are emulsified in water using an emulsifier becomes extremely poor.

As the third component of the composition A, HLB is 1
0 to 15, pH 6.5 or less, and ionic conductivity of 30
A nonionic surfactant having a μmho / cm or less is used. The third component is the first component, the second component,
And substantially the same as the sixth component used for emulsifying the platinum-based compound in the composition B, which is used for emulsifying a mixture with water.

The nonionic surfactants used in the present invention include those of alkyl allyl ether type such as polyoxyethylene nonyl phenyl ether and polyoxyethylene octyl phenyl ether, polyoxyethylene lauryl ether, polyoxyethylene tridecyl. Examples thereof include alkyl ether type such as ether, and alkyl ester type such as polyoxyethylene oleate and polyoxyethylene laurate.

When a surfactant having an HLB of 10 to 15 and a pH of 6.5 or less and an ionic conductivity of not more than 30 μmho / cm is used, the first component, the second component,
The emulsion with the component and water undergoes a dehydrogenation reaction with the passage of time and is transformed. In addition, the fourth used in the composition A
Water is used as a component and the seventh component used in the composition B.

The fifth component of the composition B includes a platinum complex (a complex of polysiloxane with platinum or a platinum compound,
Polysiloxanes containing chloroplatinic acid and various olefins) are used. This fifth component is the first component described above.
It is used as a catalyst for performing an addition reaction between the component and the second component, and has a viscosity of 10 to 500 at 25 ° C.
cs, but especially 50 to 400 cs
It is preferred that If the viscosity is less than 10 cs, emulsification by the emulsifier of the sixth component will be incomplete,
The storage stability and the pot life become unsatisfactory, and the curing during use becomes insufficient.

The second component when the first component is 100 parts by weight
The amounts of the components to the seventh component are as follows. The compounding amount of the organohydrogenpolysiloxane as the second component may be in accordance with the amount of the vinyl group contained in the first component. It is in the range of parts by weight.

The compounding amount of the nonionic surfactant as the third component is 1 to 10 parts by weight, particularly preferably 3 to 7 parts by weight. If the amount is less than 1 part by weight, emulsification becomes difficult,
In addition, the resulting emulsion lacks stability. On the other hand, when the compounding amount exceeds 10 parts by weight, not only the curability and the residual adhesion ratio are remarkably reduced, but also a bad influence may be exerted on an adhesive substance in contact with a cured film formed from this composition.

The amount of the fourth component water is 80 to 23.
It is preferably 0 parts by weight. The compounding amount of water may be an amount that enables the homogeneous mixing of the aforementioned organopolysiloxane as the first component and the second component and the emulsifier as the third component. Therefore, the blending amount is not critical, and may be added in an amount necessary to adjust the solid content in the composition to a desired range.

The addition amount of the fifth component, ie, the platinum complex-containing polysiloxane, is 0.5 to 5 parts by weight. Fifth
If the added amount of the component is less than 0.5 parts by weight, the variation in weighing greatly affects the actual use, and the composition B
Is added to composition A, poor dispersion occurs. If the amount exceeds 5 parts by weight, the pot life becomes insufficient and the economy becomes disadvantageous. The compounding amount of the nonionic surfactant as the sixth component is 0.05 to 5 parts by weight (10% of the fifth component).
It is 10 to 100 parts by weight based on 0 parts by weight, preferably 0.075 to 2.5 parts by weight (15 to 50 parts by weight based on 100 parts by weight of the fifth component).

The compounding amount of water as the seventh component is 1.5 to 1
9.5 parts by weight (300 parts per 100 parts by weight of the fifth component)
To 390 parts by weight). The compounding amount of water may be an amount that allows homogeneous mixing of the platinum-based complex-containing polysiloxane as the fifth component and the nonionic surfactant as the sixth component. Instead, the active ingredient in the composition B may be added so that it can be adjusted to a desired range.

The aqueous emulsion composition A is obtained by uniformly mixing predetermined amounts of the first to fourth components, and then emulsifying the mixture with a homogenizer or the like. In addition, in order to suppress the activity of the platinum-based complex catalyst,
If necessary, an activity inhibitor such as various organic nitrogen compounds, organic phosphorus compounds, and acetylene compounds may be added as a pot life extender.

For the purpose of preservation, sorbic acid, sorbate, acetic acid and the like may be added. Also, in order to prevent penetration into a porous base material and to increase the peeling force, for example, methylcellulose, sodium acetate, etc. A water-soluble resin such as dium carboxymethyl cellulose and polyvinyl alcohol can also be added. Further, depending on the purpose of use, a small amount of a non-reactive organopolysiloxane may be added as a slipperiness imparting agent in addition to a leveling agent for improving the leveling at the time of coating, a small amount of a solvent, and the like.

Aqueous emulsion composition A in the present invention
Is extremely stable in terms of performance, even after being left at 40 ° C. for one month, or even once frozen or thawed,
By adding the composition B, it has an ability to form a sufficient cured film. Next, an aqueous emulsion composition B
This is a production method of, similar to the case of the composition A, after uniformly mixing a predetermined amount of the fifth component to the seventh component,
It is obtained by emulsification using a homogenizer or the like. The performance and the storage stability of this composition B are extremely stable.

Immediately before use, the silicone composition of the present invention is added to an aqueous emulsion composition A comprising the first to fourth components and a predetermined amount of an aqueous emulsion composition B comprising the fifth to seventh components. Is added and mixed with stirring. The application of the silicone composition of the present invention to a substrate,
Any method such as roll coating, gravure coating, air knife coating, wire coating, doctor coating, or brush coating may be used.

The silicone composition of the present invention is applied to a flexible thin film material such as paper or film in a solid content of 0.1 to 5 g / m ^2.
And cured using a heating roll, heating drum or circulating hot air dryer at 80 to 200 ° C. for 5 seconds to 3 minutes to form a cured film.

[0039]

Further, the cured film has excellent peelability and residual adhesiveness. Furthermore, since it is a two-pack type that can use a conventional coating machine as it is, it is excellent in workability and economical. Further, it can be applied to a porous base material in combination with a water-soluble resin.

The curability, releasability (peeling resistance), and residual adhesiveness (residual adhesiveness) of the product of the present invention and the comparative product used in Examples and Comparative Examples were evaluated by the following methods.

[Curability] The composition for release was applied to the surface of PE (polyethylene) laminated paper (weighing 90 g / m ² ).
It was applied using a wire bar so as to have a silicone solid content of about 1.0 g / m ² , and then treated in a hot air circulating drying oven at 150 ° C. to form a cured film. The determination of the curability was carried out by measuring the time (seconds) until the coated surface did not fall off even when the coated surface was rubbed with a finger and hardened to such an extent that a cloudy state could be maintained. In the test, the composition within 1 hour after the preparation of the composition treatment bath and the treatment bath were used for 25 hours.
The test was performed on the composition after storage at 1 ° C. for 1 day.

[Release Resistance] The release composition was applied to the surface of a PE laminated paper (weighing 90 g / m ² ) so as to have a silicone solid content of about 1.0 g / m ^2, and then 150 μm.
The composition was treated in a hot-air circulating drying oven at ℃ to form a cured film. The curing time was the minimum number of seconds for curing each composition.

Then, an acrylic solvent-based adhesive BPS-5127 (trade name, manufactured by Toyo Ink Mfg. Co., Ltd.) was applied to the cured film surface and heat-treated at 100 ° C. for 3 minutes.
A high quality paper of 64 g / m ² was bonded to the treated surface. The obtained sheet was aged at 25 ° C. for 20 hours, and then cut into a width of 5 cm to prepare a test piece. Using a tensile tester, the high-quality paper was pulled at an angle of 180 ° at a peeling rate of 0.3 m / min, and the force (g) required for peeling was measured.

[Residual Adhesion] A curable film was formed on a PE laminated paper in the same manner as in the peel resistance test. A polyester tape [Lumirror 3]
1B: Nitto Denko Corporation product name] and 70
After heating at 20 ° C. for 20 hours under a load of 20 g / cm ² , the polyester tape (25 mm width) was peeled off, and the cured film surface was adhered to a stainless steel plate.

Next, the tape was peeled at an angle of 180 ° at a peeling speed of 0.3 m / min, and the force (g) required for the peeling was measured. On the other hand, a polyester tape (Lumirror 31B) was stuck to a Teflon plate and
After the same heat treatment under a load of 20 g / m ² for 0 hour, the polyester tape (25 mm width) is peeled off and attached to a stainless steel plate. Similarly, the force (g) required to peel off the stainless steel plate Was measured. The residual adhesion was defined as a percentage of the former force relative to the latter force.
