The present invention relates to a new and useful thermosetting resin composition, and more particularly, it contains a hydroxyl group-containing compound and a specific alkoxysilane-modified resin as essential components, and does not generate harmful substances during curing. It has excellent curability and can provide a cured product with good physical properties and solvent resistance.
The present invention relates to resin compositions useful as paints, adhesives, sealants, general molding, and the like. In recent years, there has been a growing trend toward non-polluting paints in fields such as the paint industry. Conventional thermosetting resin compositions, such as polyurethane paints that use polyisocyanate as a curing agent, have problems with toxicity due to raw isocyanate remaining in the polyisocyanate resin that is the curing agent. Melamine paints that use hardening agents have had the problem of generating toxic formaldehyde during curing. Furthermore, even when a hydroxyl group-containing polymer is used with blocked isocyanate as a curing agent, the curing temperature is high. As a result of extensive research in view of the above points, the present inventors have found that a hydroxyl group-containing compound is modified with a trialkoxysilyl group-containing compound (alkoxysilane-modified resin).
By blending, it has excellent curability and
The inventors of the present invention have completed the present invention by discovering that a cured coating film with good physical properties and solvent resistance can be obtained from a composition that does not generate harmful substances during curing. That is, the present invention includes a compound (A) having a hydroxyl group as an essential component, and a combination of the compound (A) and the general formula [However, R 1 , R 2 and R 3 in the formula are each,
Monovalent hydrocarbons with linear or branched alkyl groups, alkyl groups substituted with halogen atoms or alkoxy groups, phenyl groups, nuclear-substituted phenyl groups, or aralkyl groups, which may be the same or different; shall represent the group. ] We provide a thermosetting resin composition comprising an alkoxysilane modified resin (B) obtained by reacting with a compound having at least one trialkoxysilyl group per molecule represented by The composition of the present invention having such a structure can be widely used not only as a paint but also as an adhesive, a sealant, or for general molding. The above-mentioned hydroxyl group-containing compound (A) constituting the composition of the present invention refers to a compound having at least one, preferably two or more hydroxyl groups per molecule, and representative examples of such hydroxyl group-containing compound (A) Examples include saturated or unsaturated polyester resins,
Resins containing hydroxyl groups (hereinafter abbreviated as hydroxyl group-containing resins) such as alkyd resins, hydroxyl group-containing vinyl polymers, polyurethane resins, polybutadiene glycols, or epoxy resins,
Or unsaturated monohydric alcohols such as oleyl alcohol, linoleyl alcohol or linolenyl alcohol; partial esterification products of unsaturated fatty acids and polyhydric alcohols such as oleic acid, linoleic acid or linoleic acid; ethylene glycol, diethylene glycol, Polyethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, polytetramethylene glycol, 1,4-butanediol, 1,3-butanediol, 1,6-hexanediol, cyclohexanedimethanol, neopentyl glycol, glycerin, 3 - polyhydric alcohols such as methylpentane-1,3,5-triol, trimethylolpropane, pentaerythritol or sorbitol; and also obtained by reacting various hydroxyl group-containing compounds as described above with ε-caprolactone. There are ester compounds containing a hydroxyl group. Among them, in order to prepare the above-mentioned hydroxyl group-containing vinyl polymer, a mixture of a hydroxyl group-containing vinyl monomer and another vinyl monomer copolymerizable with the monomer is polymerized. Alternatively, a vinyl acetate homopolymer or copolymer may be hydrolyzed. Typical vinyl monomers containing hydroxyl groups include hydroxyalkyl esters of (meth)acrylic acid such as 2-hydroxyethyl (meth)acrylate or 2-hydroxypropyl (meth)acrylate, and N-methylol ( meth)acrylamide, etc. On the other hand, typical examples of other vinyl monomers that can be copolymerized with such hydroxyl group-containing vinyl monomers include methyl (meth)acrylate,
(meth)acrylic acid esters such as ethyl (meth)acrylate, butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, cyclohexyl (meth)acrylate or benzyl (meth)acrylate; monoalkyl or dialkyl esters of dibasic acids such as styrene;
Aromatic vinyl compounds such as α-methylstyrene or vinyltoluene; also vinyl acetate, vinyl chloride, (meth)acrylonitrile, N,N-
dialkylaminoalkyl (meth)acrylate (meth)acrylic acid, crotonic acid, itaconic acid,
Examples include fumaric acid, maleic anhydride, maleic acid, N-alkoxymethyl (meth)acrylamide, and (meth)acrylamide. In order to prepare the above-mentioned vinyl polymer, any known method such as solution, bulk or suspension polymerization can be used, but solution radical polymerization is most preferred. In order to prepare a polyester resin or an alkyd resin containing a hydroxyl group, known alcohols and carboxylic acids may be reacted by a known method. Furthermore, as for the polyurethane resin or epoxy resin containing hydroxyl groups, those synthesized by known methods can be used as they are, or those which have been further modified by known methods to introduce hydroxyl groups can be used. Next, the alkoxysilane-modified resin (B), which is the other component constituting the composition of the present invention, is composed of the above-mentioned hydroxyl group-containing compound (A) and the above-mentioned trioxysilane-containing compound (A) as shown in the above-mentioned general formula []. It refers to a compound obtained by reacting with a compound having at least one alkoxysilyl group in one molecule, but as one of the reaction components, a hydroxyl group-containing compound, the compound (A) as described above can be used as is. However, in particular, it is preferable to use hydroxyl group-containing ester compounds obtained by reacting various hydroxyl group-containing compounds with ε-caprolactone from the viewpoint of flexibility and adhesion of the cured resin. while methanol, ethanol, n-propanol, n
Also included are hydroxyl group-containing oligoesters obtained by addition reaction of saturated monohydric alcohols such as -butanol or 2-ethylhexanol with ε-caprolactone. As the hydroxyl group-containing compound, unsaturated monohydric alcohols as mentioned above can also be used as they are. The ε-caprolactone adduct of such a hydroxyl group-containing compound is preferably one in which about 1 to 20 moles of ε-caprolactone are added to 1 equivalent of the hydroxyl group in the presence of a known and commonly used catalyst. On the other hand, typical compounds having at least one trialkoxysilyl group per molecule, which are the other reaction components, include tetramethyl silicate, tetraethyl silicate, tetrabutyl silicate, and tetra(2-methoxyethyl).
silicic ester acids such as silicate, tetra(2-chloroethyl) silicate, tetraphenyl silicate or tetrabenzyl silicate; condensates of the above silicic esters such as tetraethyl silicate dimer, tetraethyl silicate tetramer or tetraethyl silicate hexamer; Silane coupling agents such as vinyltrimethoxysilane, vinyltriethoxysilane or glycidoxypropyltrimethoxysilane, γ-methacryloxypropyltrimethoxysilane, or 3-(β-aminoethyl)aminopropyltrimethoxysilane; trimethoxy Hydrosilanes such as silane or triethoxysilane; or compounds having one or more allylic double bonds per molecule such as allyl acetate, allyl benzoate, diallyl phthalate, diallyl adipate, diallyl succinate or triallyl trimellitate; Additives with the above-mentioned hydrosilanes; and vinyl polymers containing alkoxysilyl groups in their side chains. These may be used alone or as a mixture of two or more. Among these, from the viewpoint of cost, it is particularly preferable to use silicic acid esters such as tetramethyl silicate or tetraethyl silicate, or condensates thereof. In order to obtain the modified resin (B) using both of these reaction components, it is sufficient to react them at 60 to 200°C in the presence of a known and commonly used catalyst. The alcohol produced by charging and heating may be removed from the system under normal pressure or reduced pressure, or the alcohol produced may be removed by dropping the hydroxyl group-containing compound component into a mixture of the trialkoxysilyl group-containing compound component and the catalyst. The reaction may be carried out by distilling it off. At this time, when the content of hydroxyl groups per molecule of the hydroxyl group-containing compound component is high, gelation tends to occur if the components are charged all at once and reacted, so it is preferable to carry out the modification reaction by a dropping method. Catalysts (ester exchange catalysts) that can be used in this case include titanium compounds such as tetraisopropyl titanate or tetrabutyl titanate; acidic catalysts such as sulfuric acid, phosphoric acid, alkylated phosphoric acid, or hydrochloric acid; or lithium hydroxide, sodium hydroxide, water Typical examples include potassium oxide, sodium methylate, or alkaline substances such as triethylamine or tributylamine, and among these, it is particularly preferable to use titanium compounds. The ratio of both reaction components used in such a modification reaction is such that the trialkoxysilyl group in the trialkoxysilyl group-containing compound is 0.6 to 10 equivalents per equivalent of the hydroxyl group contained in the hydroxyl group-containing compound;
The amount is preferably selected to be 0.8 to 10 equivalents. When this equivalent ratio is less than 0.6, gelation tends to occur during the reaction, which is not preferable; however, even if it is used in a large amount exceeding 10 equivalents, there is no adverse effect on the synthesis or on the properties of the resulting resin. , from the point of view of price alone, it is better to reduce the amount to 10 equivalents or less. During such modification reactions, the reaction temperature (usually
When the hydroxyl group-containing compound is a liquid substance at 100 to 140°C, it can be carried out without using a solvent, but if the compound is a solid substance,
Alternatively, if the compound and the trialkoxysilyl group-containing compound do not mix uniformly at such temperatures, it is preferable to use a solvent with a relatively high boiling point that does not react with both of the reaction components. Typical examples include butyl acetate, xylene, "cellosolve acetate," cyclohexanone, or methyl isobutyl ketone. In addition, even if the trialkoxysilyl group-containing compound is used in excess of the hydroxyl group-containing compound as a partner component during such modification reactions, unreacted components may be contained in the reaction system as long as there is no problem. It can be used as it is as component (B) of the composition of the present invention, and of course, in cases where unreacted trialkoxysilyl group-containing compounds remain and give unfavorable results in terms of performance, It can also be removed by methods such as vacuum distillation. The composition of the present invention contains the above-mentioned hydroxyl group-containing compound (A) and alkoxysilane-modified resin (B) as essential components; % and component (B) in a range of 5 to 95% by weight, and if necessary, the composition of the present invention may contain a compound that reacts with hydroxyl groups to cause crosslinking. A crosslinking agent (C) component such as the following may be blended.
