る。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.

い問題も発生する。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.

1〜15wt%であるとよい。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%.

使用することができる。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.
