【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a low-viscosity curable resin composition for producing fiber-reinforced plastics (hereinafter abbreviated as FRP) having excellent composite physical properties. More specifically, it cures in a short time and has high heat resistance.
This invention relates to a curable resin composition with low viscosity and long pot life for producing FRP by filament winding method. The filament winding method is a molding method in which reinforcing material is impregnated with liquid resin and wound around a mandrel, and has traditionally been used to manufacture pipes and tanks. This molding method requires the reinforcing material to be continuously impregnated with resin, so a low-viscosity liquid resin must be used, and the resin composition must have a long pot life in order to produce large molded products. Due to these restrictions, currently epoxy resins and unsaturated polyester resins are mainly used as resins. Epoxy resins have excellent physical properties and heat resistance of cured products, but they generally have high viscosity and there are few resins that are suitable for filament winding. Epoxy resins using acid anhydrides are used. However, when a reactive diluent is added to this epoxy resin, the heat resistance decreases, and when an acid anhydride curing agent is used, the curing characteristics are affected by moisture absorption of the curing agent during filament winding. Performance is likely to deteriorate.
Furthermore, both have long curing times. on the other hand,
Unsaturated polyester resin has a low viscosity, a long pot life, and cures in a short time, but has low heat resistance. Furthermore, unsaturated polyester resin has poor adhesion to carbon fibers in carbon fiber reinforced plastics.
Since the elongation of the resin is also small, the interlaminar shear strength is low. Therefore, in order to compensate for the drawbacks of epoxy resins and unsaturated polyester resins, curable unsaturated esters, that is, vinyl esters, were developed by adding α,β unsaturated carboxylic acids such as acrylic acid and methacrylic acid to epoxy resins. This resin has both the excellent physical properties of an epoxy resin and the curability of an unsaturated polyester resin, and has largely overcome the drawbacks of both of the above, but a resin with good heat resistance has not yet been obtained. In this way, epoxy resin, unsaturated polyester resin, and vinyl ester resin each have their own drawbacks, and in the near future industrial materials such as drive shafts made using the filament winding method will be used.
There is no material that completely satisfies the requirements of FRP matrix resins: good mechanical properties, high heat resistance, low viscosity, long pot life, and short curing time. Therefore, the present inventors conducted research to develop a matrix resin for filament winding that satisfies the above-mentioned requirements, and as a result, they arrived at the present invention. That is, in the present invention, like conventional vinyl ester resins, an epoxy resin and an α,β unsaturated carboxylic acid such as acrylic acid or methacrylic acid are reacted in advance, and a crosslinking monomer such as styrene is added thereto. Rather than being cured by radical polymerization, the resin composition consists of an epoxy resin, an unsaturated carboxylic acid, a crosslinking monomer, and a radical reaction initiator, and the reaction between the epoxy group and the carboxylic acid is carried out simultaneously with radical polymerization by heating. This invention relates to a resin composition that is cured by. In the resin composition of the present invention, it is necessary that the epoxy group of the epoxy resin reacts with the carboxylic acid at the same time as radical polymerization, that is, the reaction occurs without a catalyst and only by heating. Such epoxy resins include polyglycidylamines, and more specifically, polyglycidylamines include N, N,
N',N'tetraglycidyldiaminodiphenylmethane, N,N,N',N'-tetraglycidyl-m
Examples include -xylene diamine, N,N-diglycidylaniline, and triglycidyl isocyanurate. The carboxylic acids used in the present invention include those that react with epoxy groups and undergo radical polymerization;
That is, it is a carboxylic acid represented by the general formula CH 2 = CR (CH 2 ) o -COOH, such as acrylic acid, methacrylic acid, vinyl acetic acid, allyl acetic acid, Δ
〓-n-hexenoitsic acid and the like can be mentioned. Furthermore, anhydrides thereof can be used as these unsaturated carboxylic acids. However, from the viewpoint of mechanical properties and heat resistance, acrylic acid and methacrylic acid are preferred. Next, the mixing ratio of the epoxy resin and carboxylic acid used in the present invention may be such that 1 equivalent of carboxylic acid per 1 equivalent of epoxy group in the epoxy resin. However, if necessary, this ratio may be changed to adjust the physical properties of the cured product or the pot life, but in order to effectively carry out the present invention, it is necessary to
It is desirable to mix the carboxylic acids in a proportion of 1.4 to 0.6 equivalents. Further, as the crosslinking monomer used in the present invention, any monomer that undergoes radical polymerization such as styrene, diallyl phthalate, diallyl isophthalate, acrylic ester, and methacrylic ester may be used. , diallyl phthalate, and diallyl isophthalate are preferred. The mixing ratio of this crosslinking monomer is 0.1~
The amount is 60 parts, but from the viewpoint of heat resistance, a range of 1.0 to 40 parts is desirable. The curing temperature for effectively implementing the present invention is 80~
A range of 160°C is preferred. For this reason, the radical initiators used in the present invention, such as benzoyl peroxide, t-butyl perbenzoate, dicumyl peroxide, and di-t-butyl peroxide, are suitable for use in the temperature range of 80 to 160°C. Any radical reaction initiator that causes radical polymerization may be used, and is not particularly limited. moreover,
160-170℃ to improve mechanical properties and heat resistance
It is desirable to post-cure for 30 to 60 minutes. In this way, the heat distortion temperature of the cured resin of the present invention is
170℃ or higher, and the interlaminar shear strength of FRP made of the resin composition of the present invention and carbon fibers is 11 to 12.
Kg/mm 2 and has excellent composite properties. The present invention can use any reinforcing material that is normally used as a reinforcing material for FRP, such as glass fibers and organic fibers and carbon fibers, and can also be applied to the case where carbon fibers, glass fibers, etc. are used in combination. Further, the resin composition according to the present invention is not only suitable for filament winding, but also for casting molding, resin injection molding, etc., by taking advantage of the resin composition's low viscosity and long pot life. It is also suitable as a resin composition for sheet molding compounds, and if necessary, fillers such as anhydrous silica and pigments may be added thereto. The characteristics of the curable resin composition of the present invention are listed below: (1) The curing time is extremely short, similar to unsaturated polyester. (2) Contains monomers that have low reactivity at room temperature, resulting in low viscosity and a very long pot life.
Excellent workability and large-scale moldability. (3) The mixing ratio of monomers can be controlled during use, and there is no risk of changes in concentration or composition over time or denaturation, which are disadvantages of unsaturated polyester and vinyl ester resins. (4) Because it contains an epoxy resin component, it has particularly strong adhesion to carbon fibers. Hereinafter, the content of the present invention will be explained in more detail with reference to Examples. Example 1 40 g of N,N,N',N'-tetraglycidyldiaminodiphenylmethane, 36 g of styrene, 24 g of acrylic acid, and 1 g of t-butyl perbenzoate were mixed uniformly to prepare a resin liquid, and the same procedure as in Example 1 was carried out. I conducted an experiment. As a result, the viscosity at 25°C was 3 poise and the pot life was over 20 hours. Also,
The ILSS and bending properties are shown in the table, indicating that the composite has excellent physical properties. 【table】
