Description

Curable composition

The present invention relates to an organic polymer having a silicon-containing group (hereinafter also referred to as “crosslinkable silicon group”) having a hydroxyl group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond. It relates to the curable composition containing this.

An organic polymer containing at least one crosslinkable silicon group in the molecule is crosslinked at room temperature by the formation of a siloxane bond accompanied by a hydrolysis reaction of a reactive silicon group due to moisture or the like. It is known to have the property of being obtained. Among these polymers having a crosslinkable silicon group, organic polymers whose main chain skeleton is a polyoxyalkylene polymer or a (meth) acrylate polymer are used for sealing materials, adhesives, paints, etc. Widely used.

The curable composition used for sealing materials, adhesives, paints, etc. and the rubber-like cured product obtained by curing have various properties such as curability, adhesiveness, storage stability, mechanical properties such as modulus, strength, and elongation. Properties are required, and many studies have been made on organic polymers containing crosslinkable silicon groups.

These curable compositions containing an organic polymer having a crosslinkable silicon group are cured using a silanol condensation catalyst. Usually, organic tin-based catalysts such as dibutyltin bis (acetylacetonate) are widely used. in use. However, in recent years, toxicity of organotin compounds has been pointed out, and development of non-organotin catalysts has been demanded.

As this non-organotin-based catalyst, a dealcohol-free silicone composition using a titanium catalyst is already on the market and is widely used for many applications (for example, Patent Documents 1 to 3).
However, there are relatively few examples of adding a titanium catalyst to an organic polymer containing a crosslinkable silicon group, which are disclosed in Patent Documents 4 to 21 and the like. The curable compositions using these titanium catalysts have a problem that the curing rate is slow, and the curing rate is lowered and the viscosity is increased after storage.

Further, a curable composition containing an organic polymer containing a crosslinkable silicon group is often used as an adhesive or a sealing material, and in that case, adhesion to various types of substrates is required. In order to ensure this adhesion, so-called aminosilane having a primary amino group and an alkoxy group in the molecule is usually used. However, when an organic polymer containing a crosslinkable silicon group and a titanium catalyst are used to prepare a one-component curable composition by adding aminosilane, the composition is good after storage for a certain period, although the adhesiveness is good. If the viscosity of the product is improved and it is severe, it may harden in the container and cannot be used. Sealing materials and adhesives are not always used immediately after production, but are often stored for several months in warehouses or stores, and it is desired that their curability and viscosity be constant before and after storage. Yes.

Furthermore, saturated hydrocarbon polymers such as polyisobutylene, hydrogenated polyisoprene, and hydrogenated polybutadiene, polyoxyalkylene polymers, and (meth) acrylic acid ester polymers can be obtained with a relatively low glass transition temperature. The cured product is preferable because it is excellent in cold resistance. Polyoxyalkylene polymers and (meth) acrylic acid ester polymers are particularly preferred because of their high moisture permeability and excellent deep-part curability when made into one-component compositions.

The crosslinkable silicon group of the (A) organic polymer used in the present invention is a group having a hydroxyl group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond. As the crosslinkable silicon group, for example, a group represented by the following general formula (5) is preferable.

In the formula (5), R ³¹ represents an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, or R ³¹ ₃ represents a triorganosiloxy group represented by SiO— (R ³¹ is the same as above), and when two or more R ³¹ are present, they may be the same or different. X represents a hydroxyl group or a hydrolyzable group, and when two or more X exist, they may be the same or different. d represents 0, 1, 2, or 3, and e represents 0, 1, or 2, respectively. Further, p in the following general formula (6) need not be the same. p represents an integer of 0 to 19. However, d + (sum of e) ≧ 1 is satisfied.

The hydrolyzable group or hydroxyl group can be bonded to one silicon atom in the range of 1 to 3, and d + (sum of e) is preferably in the range of 1 to 5. When two or more hydrolyzable groups or hydroxyl groups are bonded to the crosslinkable silicon group, they may be the same or different.
The number of silicon atoms forming the crosslinkable silicon group may be one or two or more, but in the case of silicon atoms linked by a siloxane bond or the like, there may be about 20 silicon atoms.

As the crosslinkable silicon group, a crosslinkable silicon group represented by the following general formula (7) is preferable because it is easily available.

In the formula (7), R ³¹ and X are the same as those described above, and d is an integer of 1, 2 or 3. In view of curability, in order to obtain a curable composition having a sufficient curing rate, a in the formula (7) is preferably 2 or more, and more preferably 3.

Specific examples of R ³¹ include an alkyl group such as a methyl group and an ethyl group, a cycloalkyl group such as a cyclohexyl group, an aryl group such as a phenyl group, an aralkyl group such as a benzyl group, and R ³¹ ₃ SiO—. And triorganosiloxy group. Of these, a methyl group is preferred.

The hydrolyzable group represented by X is not particularly limited as long as it is a conventionally known hydrolyzable group. Specific examples include a hydrogen atom, a halogen atom, an alkoxy group, an acyloxy group, a ketoximate group, an amino group, an amide group, an acid amide group, an aminooxy group, a mercapto group, and an alkenyloxy group. Among these, a hydrogen atom, an alkoxy group, an acyloxy group, a ketoximate group, an amino group, an amide group, an aminooxy group, a mercapto group, and an alkenyloxy group are preferable, and an alkoxy group, an amide group, and an aminooxy group are more preferable. An alkoxy group is particularly preferred from the viewpoint of mild hydrolysis and easy handling. Among the alkoxy groups, those having a smaller number of carbon atoms have higher reactivity, and the reactivity increases as the number of carbon atoms increases in the order of methoxy group> ethoxy group> propoxy group. Although it can be selected according to the purpose and use, a methoxy group or an ethoxy group is usually used.

Specific examples of the crosslinkable silicon group include trialkoxysilyl groups [—Si (OR) ₃ ] such as trimethoxysilyl group and triethoxysilyl group, dialkoxy such as methyldimethoxysilyl group and methyldiethoxysilyl group. A silyl group [—SiR ¹ (OR) ₂ ], and a trimethoxysilyl group is more preferable. Here, R is an alkyl group such as a methyl group or an ethyl group.

Moreover, the crosslinkable silicon group may be used alone or in combination of two or more. The crosslinkable silicon group can be present in the main chain, the side chain, or both.

The number of silicon atoms forming the crosslinkable silicon group is one or more, but in the case of silicon atoms linked by a siloxane bond or the like, it is preferably 20 or less.

The organic polymer having a crosslinkable silicon group may be linear or branched, and its number average molecular weight is about 500 to 100,000 in terms of polystyrene in GPC, more preferably 1,000 to 50,000. Particularly preferred is 3,000 to 30,000. If the number average molecular weight is less than 500, the cured product tends to be disadvantageous in terms of elongation characteristics, and if it exceeds 100,000, the viscosity tends to be inconvenient because of high viscosity.

In order to obtain a rubber-like cured product having high strength, high elongation, and low elastic modulus, the average number of crosslinkable silicon groups contained in the organic polymer is 0.8 or more in one molecule of the polymer. 1.1 to 5 may be present. If the number of crosslinkable silicon groups contained in the molecule is less than 0.8 on average, the curability becomes insufficient and it becomes difficult to develop good rubber elastic behavior. The crosslinkable silicon group may be at the end of the main chain or the side chain of the organic polymer molecular chain, or at both ends. In particular, when the crosslinkable silicon group is only at the end of the main chain of the molecular chain, the effective network length of the organic polymer component contained in the finally formed cured product is increased, so that the strength and elongation are high. It becomes easy to obtain a rubber-like cured product exhibiting a low elastic modulus.

The polyoxyalkylene polymer is essentially a polymer having a repeating unit represented by the following general formula (8).
-R ³² -O- (8)
In the general formula (8), R ³² is a linear or branched alkylene group having 1 to 14 carbon atoms, preferably a linear or branched alkylene group having 1 to 14 carbon atoms, and more preferably 2 to 4 carbon atoms. .

Specific examples of the repeating unit represented by the general formula (8) include
_{-CH 2 O -, - CH 2} CH 2 O -, - CH 2 CH (CH 3) O -, - CH 2 CH (C 2 H 5) O -, - CH 2 C (CH 3) 2 O-, —CH ₂ CH ₂ CH ₂ CH ₂ O—
Etc. The main chain skeleton of the polyoxyalkylene polymer may be composed of only one type of repeating unit, or may be composed of two or more types of repeating units. In particular, when used as a sealant or the like, a polymer comprising a propylene oxide polymer as a main component is preferable because it is amorphous or has a relatively low viscosity.

As a method for synthesizing a polyoxyalkylene polymer, for example, a polymerization method using an alkali catalyst such as KOH, for example, JP-A Nos. 61-197631, 61-215622, 61-215623, and 61-215623 can be used. Polymerization methods using an organoaluminum-porphyrin complex catalyst obtained by reacting an organoaluminum compound with porphyrin as shown, for example, double metal cyanide complexes shown in JP-B-46-27250 and JP-B-59-15336 Examples of the polymerization method using a catalyst include, but are not limited to, a polymerization method. A polyoxyalkylene system having a high molecular weight with a number average molecular weight of 6,000 or more and Mw / Mn of 1.6 or less and a narrow molecular weight distribution according to a polymerization method using an organic aluminum-porphyrin complex catalyst or a polymerization method using a double metal cyanide complex catalyst A polymer can be obtained.

The main chain skeleton of the polyoxyalkylene polymer may contain other components such as a urethane bond component.

The reaction can be carried out by reacting a compound having a reactive functional group and a crosslinkable silicon group (hereinafter referred to as a polymer reaction method).

As a specific example of the polymer reaction method, a hydrosilane or mercapto compound obtained by allowing a hydrosilane having a crosslinkable silicon group or a mercapto compound having a crosslinkable silicon group to act on an unsaturated group-containing polyoxyalkylene polymer to form a crosslinkable silicon group The method of obtaining the polyoxyalkylene type polymer which has this can be mention | raise | lifted.

Other specific examples of the polymer reaction method include a method of reacting a polyoxyalkylene polymer having a hydroxyl group at a terminal with a compound having an isocyanate group and a crosslinkable silicon group, or a polyoxyalkylene system having an isocyanate group at a terminal. Examples thereof include a method of reacting a polymer with a compound having an active hydrogen group such as a hydroxyl group or an amino group and a crosslinkable silicon group. When an isocyanate compound is used, a polyoxyalkylene polymer having a crosslinkable silicon group can be easily obtained.

The saturated hydrocarbon polymer is a polymer that does not substantially contain a carbon-carbon unsaturated bond other than an aromatic ring, and the polymer constituting the skeleton thereof is (1) ethylene, propylene, 1-butene, isobutylene, etc. (2) Diene compounds such as butadiene and isoprene are homopolymerized or copolymerized with the above olefin compounds. After that, it can be obtained by a method such as hydrogenation. However, isobutylene polymers and hydrogenated polybutadiene polymers are easy to introduce functional groups at the terminals, control the molecular weight, and the number of terminal functional groups. Therefore, an isobutylene polymer is particularly preferable.

Those whose main chain skeleton is a saturated hydrocarbon polymer have characteristics of excellent heat resistance, weather resistance, durability, and moisture barrier properties.

In the isobutylene-based polymer, all of the monomer units may be formed from isobutylene units, or may be a copolymer with other monomers, but the repeating unit derived from isobutylene is 50 from the viewpoint of rubber properties. Those containing at least mass% are preferred, those containing at least 80 mass% are more preferred, and those containing from 90 to 99 mass% are particularly preferred.

As a method for synthesizing a saturated hydrocarbon polymer, various polymerization methods have been reported so far, but many so-called living polymerizations have been developed in recent years. In the case of saturated hydrocarbon polymers, particularly isobutylene polymers, the inifer polymerization found by Kennedy et al. (J. P. Kennedy et al., J. Polymer Sci., Polymer Chem. Ed. 1997, 15, 2843). It is known that a polymer having a molecular weight of about 500 to 100,000 can be polymerized with a molecular weight distribution of 1.5 or less, and various functional groups can be introduced at the molecular ends.

These may be used alone or a plurality of them may be copolymerized. Especially, the polymer which consists of a styrene-type monomer and a (meth) acrylic-acid type monomer from the physical property of a product etc. is preferable. More preferred is a (meth) acrylic polymer comprising an acrylate monomer and a methacrylic acid ester monomer, and particularly preferred is an acrylic polymer comprising an acrylate monomer. In applications such as general construction, a butyl acrylate monomer is more preferred from the viewpoint that physical properties such as low viscosity of the blend, low modulus of the cured product, high elongation, weather resistance, and heat resistance are required. On the other hand, in applications that require oil resistance, such as automobile applications, copolymers based on ethyl acrylate are more preferred. This polymer mainly composed of ethyl acrylate is excellent in oil resistance but tends to be slightly inferior in low temperature characteristics (cold resistance). Therefore, in order to improve the low temperature characteristics, a part of ethyl acrylate is converted into butyl acrylate. It is also possible to replace it. However, as the ratio of butyl acrylate is increased, its good oil resistance is impaired. Therefore, for applications requiring oil resistance, the ratio is preferably 40% or less, and more preferably 30% or less. More preferably. It is also preferable to use 2-methoxyethyl acrylate or 2-ethoxyethyl acrylate in which oxygen is introduced into the alkyl group in the side chain in order to improve low temperature characteristics and the like without impairing oil resistance. However, since heat resistance tends to be inferior due to the introduction of an alkoxy group having an ether bond in the side chain, when heat resistance is required, the ratio is preferably 40% or less. In accordance with various uses and required purposes, it is possible to obtain suitable polymers by changing the ratio in consideration of required physical properties such as oil resistance, heat resistance and low temperature characteristics. For example, although not limited, examples of excellent balance of physical properties such as oil resistance, heat resistance, and low-temperature characteristics include ethyl acrylate / butyl acrylate / -2-methoxyethyl acrylate (40-50 / 20 by mass ratio). To 30/30 to 20).
