Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curing agent for radically curable resins and a fixing agent for anchor bolts containing the same.

[0002]

2. Description of the Related Art Conventionally, as a polymerization initiator such as an unsaturated polyester resin, an epoxy acrylate resin, or a polyester acrylate resin, which is a radical-curable resin, a curing agent containing an organic peroxide as a main component has been used. These curing agents are used according to the purpose of use and the temperature at which they are used, and are often used in combination with a curing accelerator such as aromatic amines in a low temperature and normal temperature range.

The radical curable resin using an organic peroxide as a curing agent has been used in a wide variety of applications, such as a corrosion-resistant lining, a mold, and a main ingredient for a resin capsule anchor. As resin for resin capsule anchor, unsaturated polyester resin,
Epoxy acrylate resins are common.

A resin capsule anchor is used for embedding anchor bolts in a concrete structure, a bedrock, or the like, and for installing facilities and the like. There is a type that has a component and drives the anchor bolt or the reinforcing bar with a hammer, and a type that inserts while rotating and hitting with a hammer drill or the like.

[0005] A resin capsule anchor of a type in which anchor bolts and rebars are embedded while rotating and hitting with a hammer drill or the like includes a main agent curable in a crushable cylindrical container, an aggregate, and a hardener sealed in an inner container. A resin capsule anchor having a double container structure provided with an agent is generally used (Japanese Patent Publication No. 62-37076). Further, in a bolt fixing cartridge comprising a crushable outer container and a crushable inner container, one of which is filled with a viscous liquid resin, and the other is filled with a hardener and an aggregate of the viscous liquid resin, A bolt fixing cartridge (Japanese Patent Publication No. 4-1160) wherein the hardener and the aggregate are substantially uniformly mixed; a viscous liquid resin; and a granular aggregate mixed with the viscous liquid resin. An organic binder, a diluent, and a peroxide are molded into a rod, and a curing agent having a resin coating layer over the entire surface of the rod-shaped molded product is filled in an opaque cylindrical tube, 2. Description of the Related Art There is known a fixing agent for fixing a bolt in which a transparent plastic cap is closely fitted to the mouth of an opaque cylindrical tube (Japanese Patent Publication No. 63-13000).

There is also known an anchor bolt sealing cartridge in which a curable polymer system is divided into a plurality of sections by macroencapsulation, and these macrocapsules are formed as a fixed three-dimensional cylindrical arrangement (Japanese Patent Application Laid-Open No. H10-163,837). No. 55-32814). These are configured such that when the capsule is crushed, the wall material of the capsule forms flake-like debris, and the flake functions as a “static stirrer” to achieve uniformity of the polymerization system.
For this purpose, the capsules are arranged in a three-dimensional cylindrical arrangement in which the capsules are substantially fixed, so that the capsules are reliably crushed by inserting bolts. The capsule must also be such that the wall material can form flake pieces.

Further, as a curing composition which is not a fixing agent for anchor bolts but is used for applications such as adhesives, sealants, coating materials, molding materials, etc., a polymerizable polyacrylate and / or polymethacrylate and an organic peroxide are used. A redox system with the organic peroxide to form a polyacrylate and / or polymethacrylate as an internal phase, and a film formed of a film-forming hydrocarbon compound. There is also known a one-part curable composition obtained by dispersing multiple microcapsules coated on an inner wall film (JP-B-54-32480).

[0008]

The curing agent for the radical-curable resin is generally liquid, powdery or granular diluted with an inorganic or organic substance. These liquid, powdery, and granular hardeners are mixed with a radical-curable resin and poured into a mold or a hole, whereby the hardener is uniformly mixed with the resin in a short time. However, for example, when these curing agents are used as anchoring agents for anchor bolts and are commonly used in resin capsule anchors having a well-known double-container structure, the curing agent is filled in a thin inner container. Is difficult to fill, and the workability becomes very poor.The work environment is deteriorated due to the scattering of fine powder of the curing agent when filling into the container, and the bridging of the curing agent in the filling hopper and the container occurs, resulting in poor workability. There is a problem that it gets worse. Further, the occurrence of the bridge causes a shortage of the amount of the hardener to be injected into the capsule, but it is difficult to detect the non-injection or the shortage of the hardener.

The fixing agent for fixing bolts disclosed in Japanese Patent Publication No. 63-13000 solves the above-mentioned problems. However, this fixing agent for bolts cannot be mixed and filled with granular aggregate during capsule production because the molded product of the hardening agent is rod-shaped, and the granular aggregate must be filled after the rod-shaped hardening agent is loaded. There is a drawback that waste of productivity such as inability to produce the granules or bridging of the granular aggregate to be filled occurs in the gap between the cylindrical tube and the rod-shaped hardener, resulting in poor sedimentation of the granular aggregate. In addition, the rod-shaped hardener often breaks due to the rotation or impact of the hammer drill when the anchor bolt is embedded, causing uneven mixing with the viscous liquid resin, causing a large variation in the fixing performance and a problem in that stable high fixing performance cannot be exhibited. Also occurs.

In the technique disclosed in Japanese Patent Application Laid-Open No. 55-32814, a phenol resin-glass sphere capable of forming a flake piece when a usable macrocapsule itself is crushed,
It is limited to hollow clay pillows, gelatin capsules and the like. Therefore, the method of filling the components into the macrocapsules is limited, and the capsules are immersed in vacuum in the components,
Alternatively, it is carried out by a method of low productivity such as using a syringe, and its components are limited to liquid components and cannot be applied to solid and powder components.

The present invention provides a curing agent for a radical-curable resin having a long product life and excellent handleability, exhibits high fixing performance, is excellent in manufacturability, and has a high reliability without a problem of insufficient curing agent or unfilled. An object of the present invention is to provide a high one-pack type anchor bolt fixing agent composition.

[0012]

Means for Solving the Problems In a curing agent molded product for a radical-curable resin, there is no bridge in a container by forming a granular molded product with a curing agent and a component inert to the radical-curable resin, Uniform dispersion is also possible, and it is found that by forming a coating layer made of a radical-curable resin hardened on the surface portion made of a hardening agent of a granular molded product, the productivity is excellent and the product life is prolonged. I'm sorry.

That is, the present invention relates to a granular molded product of a curing agent for curing a radical-curable resin, the surface of which comprises a curing agent and a component inert to the radical-curable resin. A cured agent molded product for a radical-curable resin characterized by having a coating layer made of a further cured radical-curable resin on the surface portion composed of

[0014] The granular molded body used in the present invention, which comprises a curing agent and a component inert to a radical-curable resin, has a form such as a columnar shape, a granular shape, a spherical shape, and a plurality of irregularities. Wherein the surface comprising the curing agent is further coated with a radical curing type resin containing a curing accelerator which undergoes a curing reaction with the curing agent. The radical-curable resin and the inactive component contained in the granular compact are not particularly limited, but glass, synthetic resin, stone, metal, inorganic compound and the like are used. As the shape, for example, one obtained by injecting a slurry-like hardening agent into a glass or synthetic resin thin tube cut into a short length and drying it, a shape obtained by bonding a synthetic resin film or a metal flake to a formed hardening agent, or a shape having irregularities A slurry obtained by attaching a slurry-like curing agent to the surface of a stone and drying it.The curing agent and the inorganic compound are each formed into granules with a molding agent. After the curing agent molded body is dried, the inorganic compound is formed before drying. Some are inserted and adhered to the body.

It is important that the molded article of the curing agent of the present invention has a component which is inactive with respect to the radical-curable resin together with the curing agent having the cured resin coating layer on its surface. The presence of the inactive component further inhibits the penetration of the radical-curable resin into the inside of the curing agent molded body, and can contribute to an improvement in product life, that is, storage stability.

Examples of the curing agent include hydroxides such as cumene peroxide; dialkyl peroxides such as dicumyl peroxide; diacyl peroxides such as benzoyl peroxide; ketone peroxides such as methyl ethyl ketone peroxide; (4-t
Oxycarbonates such as -butylcyclohexyl) peroxycarbonate; peroxyketals such as 1,1-di-t-butylperoxycyclohexanone; t-
Organic peroxides such as peroxyesters such as butyl peroxybenzoate, and those obtained by diluting these organic peroxides with organic substances such as dicyclohexyl phthalate and inorganic substances such as calcium carbonate and calcium sulfate are also included. If necessary, other components such as a molding agent and a surfactant may be added.

In consideration of safety, the curing agent of the present invention preferably has an organic peroxide content of 50% or less.
Considering room-temperature curability and safety, benzoyl peroxide diluted with a diluent is preferred. The organic peroxide / inert component ratio is, for example, from 0.1 to 80% by weight, preferably from 1 to 60% by weight.

The method for molding the curing agent is not particularly limited, and examples thereof include a method of applying a mechanical pressure to a powdery or wet material, and a method of forming a slurry containing water or the like and drying it. , A method of molding a powder through a molding agent,
There is a method in which a powdery substance is made into a clay state with water and a molding agent, and is formed into a spherical shape with a rounding machine.

Examples of molding agents include carboxymethylcellulose, methylcellulose, guar gum, locust bean gum, gelatin, PVA (polyvinyl alcohol),
Gum arabic, microcrystalline cellulose, amylose, starches of amylopectin, etc. are used, but from the viewpoint of productivity and shape retention, carboxymethylcellulose, guar gum, and cellulose derivatives of locust bean gum are preferably used, and more preferably. Are starches of amylose and amylopectin in which the granular molded body is hardened and excellent in handleability. The ratio of molding agent / hardening agent is, for example, 0 to 2
0% by weight, preferably 1 to 15% by weight.

Further, there is no particular limitation on the method of combining the curing agent and the component inactive with respect to the radical-curable resin to form a granular molded product. A method of injecting and drying a curing agent, a method of adhering a synthetic resin film or a metal flake to a molded curing agent, a method of attaching a slurry-like curing agent to a surface of uneven stone, and a method of drying, There is a method in which each of the inorganic compounds is formed into a granule with a molding agent, the curing agent molded body is dried, and then inserted and adhered to the inorganic compound molded body before drying.

The method for forming a coating layer made of a radical-curable resin on the surface of the hardener of the thus obtained granular molded product includes the following: 1) a radical-curable resin containing a hardening accelerator which reacts with the hardener. A method of coating the surface of the molded body by a process such as immersing the molded body into a coating layer, and forming a coating layer by a curing reaction at that time; 2) putting the molded body of the curing agent into a main agent containing a radical curing type resin and a curing accelerator; There is a method in which a resin coating layer is formed on the surface by a curing reaction of the above. However, when using as a fixing agent composition for anchor bolts, in consideration of simplification of the manufacturing process, cost, etc., the molded article of 2) is put into the main agent. A method of forming a resin coating layer on the surface by a curing reaction at that time is more preferable.

As the radical-curable resin containing a curing accelerator, epoxy acrylate resin, polyester acrylate resin, acrylic urethane resin, unsaturated polyester resin and the like are used.

The thickness of the coating layer is preferably as small as possible so long as the active portion of the curing agent can be sufficiently retained.
It is preferable to set it to 3 to 40%.

The coating layer is mainly composed of a radical-curable resin, and may contain an unreacted curing agent, molding agent, and the like.

Regarding the particle size of the granular molded product, considering the case where the anchoring agent for the anchor is contained in a crushable container, the aggregate and the hardening agent are not caught in the container when mixed and filled with the aggregate. 0.5mm that can be settled to
Those having a particle size of not less than 15.0 mm are preferable because of good productivity and workability. Further, those having a particle size of 1 to 10 mm which are close to the particle size of the aggregate and which can disperse the curing agent more uniformly are more preferable.

The hardness of the granular molded body is not particularly problematic as long as it can be crushed by mechanical stirring at the time of application as a fixing agent for anchor bolts. Considering that it is necessary to prevent the collapse of the granular compact during handling when mixed and filled with the aggregate, the crushing strength is 150 kgf / cm.
^{Although 2} or more is preferable, it may be 1 kgf / cm ² or more when a more durable film is formed to extend the product life.

The radical-curable resin used in the anchor bolt fixing agent of the present invention is an epoxy acrylate resin, a polyester acrylate resin, an acrylic urethane resin, an unsaturated polyester resin, or the like. Further, it is more preferable to use an epoxy acrylate resin or a polyester acrylate resin, which is excellent in fixing performance, low-temperature curability, and alkali resistance, as a main component among radical-curable resins.

Reactive monomers can be mixed and used in these radical-curable resins. Reactive monomers include styrene monomer, methyl methacrylate, ethyl methacrylate, ethylene glycol dimethacrylate, cyclohexyl acrylate, n-butyl methacrylate, 2-hydroxyethyl methacrylate, benzyl methacrylate, phenoxyethyl methacrylate, diethylene glycol dimethacrylate, triethylene glycol Ethylene glycol dimethacrylate, 1,4 butylene glycol dimethacrylate, trimethylolpropane trimethacrylate, dimethyl maleate, isobornyl methacrylate, butanediol dimethacrylate, and 2,2-bis [4- (methacryloxydiethoxy) phenyl ] And propane. These reactive monomers are, for example, 0 to 100% by weight, preferably 1% by weight, based on the radical-curable resin.
Can be used at ~ 60% by weight.

The curing accelerator used in the present invention is N, N
-Dimethylaniline, N, N-diethylaniline, N,
Aromatic anilines such as N-dimethyl-P-toluidine, N, N-dihydroxypropyl-P-toluidine, N, N-dihydroxyethyl-P-toluidine; metal soaps such as cobalt naphthenate; vanadyl acetylacetonate; And the like. These curing accelerators are, for example, 0.2 to 3% by weight based on the radical-curable resin.

The curing time of the base material of the present invention is determined by the workability and the fixing strength of the fixing agent. If the hardening time of the main agent is short, the resin will harden during embedding of the anchor bolts and embedding will not be possible.On the other hand, if the hardening time is long, the resin will not be hardened at low temperature application and will not be able to demonstrate the fixing strength, When the coating layer is formed by the main agent by directly charging the granular molded body into the main agent, the reactive monomer and the hardener component react by the reactive monomer penetrating the hardener coating layer. As a result, the hardener component is lost and the product life is shortened. For this reason, if the hardening time of the base resin is adjusted to the minimum amount of hardening time measured at 25 ° C. of JIS-K6901 (room temperature hardening characteristics) by adjusting the amount of the hardening accelerator to be added, the uncured resin during low-temperature application can be obtained. This is preferred because curing is eliminated. Further, to sufficiently exhibit the fixing strength, 4 minutes or more
5 minutes or less is more preferable. In the fixing agent composition,
It is preferable that the ratio of the organic peroxide in the hardener molded body to the main agent is 1 to 15 wt%.

The main component containing the radical-curable resin and the curing accelerator includes, if necessary, a polymerization inhibitor, a pigment, an ultraviolet absorber, a surfactant, a thickener, a filler, and a thixotropic agent (differential silica, etc.). , A coloring agent and the like can be added.

Further, by using an aggregate as the fixing agent for anchor bolts of the present invention, the hardener molding is finely crushed and the mixing effect with the main agent is improved, and after curing, the cured resin becomes harder. Is obtained, and higher fixing performance can be exhibited. When the aggregate has a relatively large particle size, it is sufficient that the aggregate can be crushed by rotation, impact, etc. at the time of anchor bolt construction, and in general, an artificial aggregate such as magnesia clinker or glass, ceramic, silica, Although an inorganic substance such as natural stone such as quartz is used, an organic substance such as hard plastic such as hard vinyl chloride may be used. The shape of the aggregate is preferably granular in consideration of dispersibility, mixing and filling with a curing agent, and the like. In addition, the particle size of the aggregate may be determined according to construction conditions (diameter of drilled hole, size of anchor bolt, etc.). The aggregate can be used in an amount of, for example, 0 to 500% by weight, preferably 50 to 300% by weight based on the main agent.

The adhesive composition obtained by the present invention may be obtained by crushing a granular molded body before or after filling the adhesive composition into a hole in which an anchor bolt is to be formed. Examples of the crushing method include a method using a mixer before filling, rotation of anchor bolts after filling,
There is a method using a blow.

The fixing composition for anchor bolts described above is
It may be poured into the perforation as it is and may be constructed by adding mechanical stirring as described above. However, by containing the material in a crushable container, the curing agent / resin ratio, the aggregate / resin ratio, etc. are kept constant. A stable and high fixing force with less variation can be exhibited. Crushable containers are those that can be crushed or torn by rotation, impact, etc. during the construction of anchor bolts, and should block penetration of radical-curable resins and curing accelerators or reactive monomers to prevent their escape. The material is not particularly limited as long as the material can be used, but usually, a cylindrical material made of a material such as glass, synthetic resin, synthetic resin film, and paper is used.
