This invention relates to improvements in adhesives used for bolt fixing. Conventionally, a bolt fixing agent containing a resin or a mixture of resin and filler and a hardening agent separately in the same container is inserted into a hole in concrete, rock or other base material, and then an anchor bolt is inserted. A method in which the anchor bolt is inserted into the hole, the bolt fixing agent is destroyed by the rotation and impact of the anchor bolt, the contents are stirred and mixed, and then the anchor bolt is fixed in the hole by a curing reaction between the resin and the hardening agent. is generally known. As such a fixing agent for bolt fixing, for example, one is known in which a glass tube is filled with a mixture of a resin and a filler (stone aggregate), and the glass tube is further filled with a powdered hardening agent. In this case, the container is extremely expensive because it is a glass container, and if it is accidentally dropped on the floor during handling, it will be easily destroyed and become completely unusable.Furthermore, if left in direct sunlight, the resin will deteriorate. There was a problem that it solidified and became unusable. In addition, since the hardening agent is sealed in a thin glass tube, it is difficult to fill the thin glass tube with the hardening agent, and furthermore, the glass tube containing the hardening agent is generally sealed using fire such as a gas burner. There were problems such as the possibility of denaturation of the curing agent due to heat during tube sealing. As another example, a hardening agent formed by compression molding a diluent, a binder, and a peroxide such as benzoyl peroxide in a plastic film tube;
Types containing a mixture of a resin and a filler are known (Utility Model Application Publications No. 56-13199 and No. 56-13200).
In this case, due to the polymerization of the resin in contact with the hardening agent, a limiting film layer is formed at the interface between this hardening agent and the mixture of resin and filler; The resin and curing agent are kept separate. However, since the progress of polymerization of the resin due to the action of the curing agent cannot be completely eliminated, there has been a problem in that this type of bolt fixing adhesive has a relatively short shelf life. Furthermore, since the hardening agent is molded with an inorganic binder, the strength of the hardening agent is relatively weak, and the hardening agent may break when handling or transporting such a bolt fixing agent, making it inconvenient to handle. There was a problem that it caused This invention was made to solve the above problems, and consists of a viscous liquid resin, granular stone aggregate mixed into the viscous liquid resin, an organic binder, a diluent, and a peroxide in a rod shape. A hardening agent formed by molding and having a resin coating layer over the entire surface of the rod-shaped molded product is filled into an opaque cylindrical tube, and a transparent plastic is placed at the mouth of the opaque cylindrical tube. The present invention provides a bolt fixing agent that tightly fits a cap. The fixing agent for bolt fixing according to this invention is shown in FIG.
This will be explained in detail with reference to FIGS. 2, 3, and 4. 1 and 3 are sectional views showing one embodiment of the present invention, and FIGS. 2 and 4 are a cross-sectional plan view taken along line A-A' in FIG. 1 and line BB' in FIG. 3, respectively. FIG. In FIG. 1, a viscous liquid resin 1 and a granular stone aggregate 2 are housed in an opaque cylindrical tube 6 together with a hardening agent 5 with a coating layer, and the mouth of the opaque cylindrical tube 6 is made of a transparent material. It is tightly fitted by a plastic cap 7. The hardening agent 5 with a coating layer consists of a hardening agent 3 molded into a rod shape and a coating layer 4 formed over the entire surface of the hardening agent. The curing agent 3 molded into a rod shape is molded into a cylindrical or quadrangular prism shape as shown in FIG. 2A and B.
In FIG. 2A, 8 is a curing agent molded into a cylindrical shape, and in FIG. 2B, 9 is a curing agent molded into a quadrangular prism shape. Further, in FIG. 3, the viscous liquid resin 1 and the granular stone aggregate 2 are housed in an opaque cylindrical tube 6 together with a hardening agent 12 having a first coating layer and a second coating layer. The mouth of the opaque cylindrical tube 6 is tightly fitted with a transparent plastic cap 7. A curing agent 12 with a coating layer having a first coating layer and a second coating layer is formed by forming a curing agent 3 formed into a rod shape and a first coating layer formed over the entire surface of the curing agent.
The second coating layer 11 is formed over the entire surface of the first coating layer. The curing agent 3 molded into a rod shape is shown in Fig. 4A,
It is molded into a cylindrical or quadrangular prism shape as shown in (B). In FIG. 4A, 13 is a curing agent molded into a cylindrical shape, and in FIG. 4B, 14 is a curing agent molded into a quadrangular prism shape. The curing agent 3 is composed of a peroxide such as benzoyl peroxide, a diluent such as calcium carbonate, calcium sulfate, or a silicate, and an organic binder such as an emulsion polymer of acrylic acid ester and styrene. The peroxide, diluent, and binder are uniformly mixed, and the peroxide and diluent are firmly bound together by the action of the organic binder. In FIGS. 1 and 2 A and B, the coating layer 4 formed over the entire surface of the curing agent 3 is made of a resin coating layer that is non-reactive with the viscous liquid resin and the curing agent, and is made of polyvinyl resin. Alcohol, polyvinyl chloride, polyvinyl acetate, cellulose acetate, etc. are used. In addition, in FIGS. 3 and 4 A and B, the first coating layer 10 formed over the entire surface of the curing agent 3 is made of a resin that is soluble in the solvent and can be obtained by removing the solvent. The resin coating layer is made of a composition and is non-reactive with the curing agent and the second coating layer, and polyvinyl alcohol, polyvinyl chloride, polyvinyl acetate, cellulose acetate, etc. are used. Furthermore, the second coating layer 11 formed over the entire surface of the first coating layer 10 is made of a thermosetting resin, and is made of a hard resin that is non-reactive with the first coating layer and the viscous liquid resin. This is a resin coating layer, and unsaturated polyester resin, epoxy resin, etc. are used. A curing agent having a coating layer as described above can be obtained by first adding and mixing a binder to a peroxide and a diluent, and forming the mixture into a rod shape and solidifying the mixture to form a coating layer. The coating layer 4 or the first coating layer 10 is prepared by immersing a curing agent 3 previously shaped into a rod shape in a solution containing either polyvinyl alcohol, polyvinyl chloride, polyvinyl acetate, or cellulose acetate.
Thereafter, the solvent is removed to obtain a resin coating layer. Furthermore, the second coating layer 11 formed over the entire surface of the first coating layer 10 is made by adding a suitable curing agent to liquid unsaturated polyester resin, epoxy resin, etc. or by immersing the first coating layer 10 in a curing agent, and then forming the second coating layer 11 made of a hard resin through polymerization and curing reactions. Here, the first coating layer 10 includes a hardening agent 3 shaped into a rod shape, for example.
When the second coating layer is formed directly on the surface of the second coating layer, it is formed to prevent the second coating layer from reacting with the curing agent during polymerization and curing of the second coating layer. be. The opaque cylindrical tube 6 is made of a mixture of phenolic resin and fillers such as wood powder, asbestos, talc, and black pigment, and is opaque and easily destroyed by the impact of a bolt during use. It is molded to be The cap provided at the mouth of the opaque cylindrical tube 6 is made of transparent plastic material, and is attached tightly to the mouth of the tube to prevent the contents inside the tube from spilling out. As the viscous liquid resin 1, an unsaturated polyester resin is suitable, and benzoyl peroxide is used as a curing agent, and dimethylaniline is used as a curing accelerator. Other epoxy resins can also be used, and amine-based hardeners and organic acid anhydride-based hardeners are used as hardeners. Since the bolt fixing agent of the present invention configured as described above has a viscous liquid resin filled in an opaque container, the adhesive of the present invention can be left in direct sunlight or in the open air. This prevents the viscous liquid resin from reacting with sunlight and solidifying (gelling). Therefore, unlike the conventional transparent glass tube filled with viscous liquid resin,
The viscous liquid resin does not solidify even if exposed to sunlight for a long time, making it safe to use. Furthermore, even if the pot life of the viscous liquid resin has expired and it has solidified, the fluidity of the viscous liquid resin inside the tube can be checked from the outside through a transparent plastic cap 7 provided at the mouth of the opaque inner cylindrical tube 6. By visually inspecting it, it is possible to easily determine whether or not it can be used. Further, the opaque cylindrical tube 6 used in the present invention is made of a phenolic resin containing a filler, so-called a plastic tube. Therefore,
It has good impact resistance, and unlike conventional glass tubes filled with resin, even if the container is accidentally dropped on the floor during handling, it will not break and become unusable. Moreover, even in actual use, the opaque cylindrical tube 6 is easily broken into pieces by the rotation and impact of the bolt, so it can be used satisfactorily as a fixing agent for bolt fixing. Furthermore, as is clear from FIGS. 1 and 3, the bolt fixing adhesive according to the present invention has a coating layer 4 between the hardening agent 3 and the viscous liquid resin 1 that is non-reactive with the hardening agent and the viscous liquid resin. , or the first coating layer 10 non-reactive with the curing agent and the second coating layer, and further the second coating layer 11 non-reactive with the first coating layer and the viscous liquid resin, covering the entire surface of the curing agent 3. Since the viscous liquid resin 1 and the curing agent 3 are formed over the area, there is no direct contact between the viscous liquid resin 1 and the curing agent 3, and there is no fear that the viscous liquid resin 1 and the curing agent 3 will react with each other before use and become unusable. In addition, the hardening agent 3 has a peroxide and a diluent firmly bound together by an organic binder, and in addition, a resin coating layer is provided over the entire surface of the hardening agent 3, so that it is not towable. properties, and the strength of the curing agent is increased. Therefore, the curing agent does not break and cause inconvenience in handling during the production of the curing agent and also during transportation of the bolt fixing adhesive according to the present invention. Furthermore, the manufacturing method for the hardening agent with a coating layer is simple, as it is only necessary to form a coating layer on the entire surface of the curing agent 5 that has been previously molded into a rod shape, and can be produced continuously and in large quantities. Furthermore, since the second coating layer made of hard resin is broken into small pieces by rotation and impact during bolt driving, it can also be effectively used as an aggregate. In addition, unlike the conventional method of filling a glass tube with a hardening agent and then sealing the glass tube with fire, there is no need to use fire during the production of the hardening agent. There is no risk of degeneration. Further, the bolt fixing adhesive according to the present invention has many advantages, such as the fact that the bolt fixing adhesive can be provided at a low cost since an expensive glass tube is not used. Example 1 A hard glass tube with an outer diameter of 13 mm, a wall thickness of 0.8 mm, and a tube length of 90 mm, and an opaque cylindrical tube made of phenolic resin containing a filler (hereinafter abbreviated as phenol tube).
were prepared and allowed to fall naturally onto a concrete floor to inspect the state of destruction. The test results are shown in Table-1.

Example 2 Five hard transparent glass tubes and phenol tubes each having an outer diameter of 13 mm, a wall thickness of 0.8 mm, and a tube length of 90 mm were filled with unsaturated polyester and the openings were sealed with caps to prepare five samples. This sample was left under direct sunlight, and the solidification time of the unsaturated polyester resin contained therein was examined. A sample in which a hard glass tube was filled with unsaturated polyester resin was completely solidified in 2 hours, whereas a sample in which a phenolic resin was filled with unsaturated polyester resin remained unsaturated even after being left in direct sunlight for 10 hours. No change was observed in the fluidity of the saturated polyester resin. Example 3 A phenol tube with an outer diameter of 13 mm, a wall thickness of 0.8 mm, and a pipe length of 90 mm is filled with a curing agent that uses cellulose acetate as the first coating layer and a polymerized cured product of unsaturated polyester resin as the second coating layer. . Next, 5 parts of the sample was filled with 1.5 parts of granular stone aggregate and 1 part of unsaturated polyester resin, and the mouth part was sealed with a transparent plastic cap.
I have prepared the book. This sample is inserted into a concrete hole with a diameter of 15 mm and a depth of 100 mm, and then a bolt with a diameter of 12.7 mm is pushed in while rotating to break the sample and mix the contents. After curing is complete, the concrete hole is cut and the contents of the sample are extracted and inspected. It was confirmed that the phenol pipe, the polymerized hardened product of unsaturated polyester resin that is the second coating layer, and the granular stone aggregate were crushed into fine particles, and that the unsaturated polyester resin and curing agent were sufficiently mixed.
