Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to concrete, bedrock, etc. (hereinafter referred to as base material).
The present invention relates to a bolt fixing cartridge for fixing an anchor bolt.

[Conventional technology]

Conventionally, as a method of fixing anchor bolts, perforating the base material,
A thermosetting resin such as unsaturated polyester resin contained in the container, which is loaded with a capsule in the hole and is inserted into the hole while the anchor bolt is inserted into the hole while rotating and striking the anchor joined to the hammer drill etc. It is known that the anchor bolt is fixed by hardening the resin (Japanese Patent Publication No. 38-12863).
Issue).

Most of the thermosetting resins used for these fixing agents are of a type that is cured by a radical reaction. Since the resin is designed to cure at room temperature, the workability of anchor construction was excellent. On the other hand, it was very sensitive to visible rays and ultraviolet rays in the sun rays and was highly reactive. When the container is a colorless glass tube, most of the light having a wavelength of 350 mm or more is transmitted, and the resin gels in a short time. Therefore, the resin is contained in the colored glass tube.

[Problems to be solved by the invention]

If it is a colored glass tube only for protecting the resin, the problem can be solved by using black glass. But,
It is not possible to check the fluidity of the resin contained in pure black glass (the fluidity check of the resin is essential for the performance check of the bolt fixing cartridge).

For brown glass, 90% at 350 nm, 80% at 450 nm, 550n
Absorption of about 40% in m. Therefore, even if the colored glass is used, the storage stability of the resin cannot be improved.

[Means for solving the problem]

An object of the present invention is to provide a bolt fixing cartridge which can withstand visible light and ultraviolet rays in sunlight for a long time without deteriorating the performance as a fixing agent.

That is, the present invention provides a bolt fixing cartridge comprising a thermosetting resin contained in a crushable container and a curing agent separated from the thermosetting resin, wherein the thermosetting resin reacts with the resin. A bolt-fixing cartridge containing a non-lake pigment, an azo pigment, a phthalocyanine pigment and / or a higher organic pigment.

The container used in the present invention is not particularly limited as long as it can be easily crushed by a rotation / striking insertion motion of an anchor bolt or the like attached to a drill at the time of construction, for example, glass, pottery, porcelain, synthetic resin, paper Etc.

The thermosetting resin used in the present invention can be easily cured at room temperature, and includes, for example, unsaturated polyester resin, vinyl ester resin, epoxy acrylate resin and the like, and a reactive monomer such as styrene monomer and methyl methacrylate. It is a mixture of bodies.

The curing agent used in the present invention is an organic peroxide such as benzoyl peroxide, methyl ethyl ketone peroxide, acetyl peroxide and the like. Further, a curing accelerator for promoting the curing of the resin can be added to the thermosetting resin. Curing accelerator used, for example, dimethylaniline, diethylaniline, amines such as dimethylparatoluidine, cobalt naphthenate, cobalt octoate, metal soaps such as manganese naphthenate,
It is a chelate compound such as vanadyl acetylacetonate and iron acetylacetonate. Further, a polymerization inhibitor such as hydroquinone or naphthoquinone may be added to maintain the stability of the resin. Further, if necessary, aggregate such as natural crushed stone such as silica or marble, or artificial stone such as magnesia clinker can be used.

In the present invention, it is necessary to contain a lake pigment, an azo pigment, a phthalocyanine pigment and / or a higher organic pigment that does not react with the resin. These pigments are those which are dissolved in the reactive monomer contained in the resin or which are substantially uniformly dispersed and colored, and do not decompose during long-term storage. For example, toner yellow, toner brown, toner Products sold under the trade names of Green [Takeda Yakuhin Co., Ltd.], Colortex Brown, Colortex Orange, Colortex Maron [Sanyo Pigment Co., Ltd.] and Oplus Yellow [Orient Science Co., Ltd.] Examples include, but are not limited to:

The compounding composition of the bolt fixing cartridge of the present invention has 100 parts by weight of the thermosetting resin as the main component, a lake pigment,
Azo pigments, phthalocyanine pigments and / or higher organic pigments
0.05 to 2.0 parts by weight, curing accelerator 0.05 to 5 parts by weight, curing agent
A range of 1.0 to 20 parts by weight is preferred.

〔Example〕

 Hereinafter, the present invention will be described in detail with reference to examples.

Example 1 100 parts by weight of unsaturated polyester resin, 1.0 part by weight of dimethylaniline, 0.2 part by weight of hydroquinone, and a pigment [Orient Science Co., Ltd.] Made, Oplas Yellow # 130]
5 g of the mixture to which 0.1 part by weight was added was filled and the container was sealed. Next, this cartridge was placed in a glass tube stand and placed in direct sunlight to perform an exposure test. The time when the fluidity of the resin disappeared (gelation time) was observed. The result is first
Shown in the table.

Example 2 A cartridge was prepared in the same manner as in Example 1 except that the pigment used in Example 1 was replaced with Donor Green [trade name, manufactured by Takeda Pharmaceutical Co., Ltd.], and an exposure test was conducted. The results are shown in Table 1.

Example 3 A cartridge was prepared and an exposure test was conducted in the same manner as in Example 1 except that the pigment used in Example 1 was changed to Colortex [manufactured by Sanyo Dye Co., Ltd., trade name]. The results are shown in Table 1.

Comparative Example 1 A cartridge was prepared and an exposure test was conducted in the same manner as in Example 1 except that the pigment was not used. The results are shown in Table 1.

[Effects of the Invention] The bolt fixing cartridge of the present invention has significantly improved light resistance by adding a lake pigment, an azo pigment, a phthalocyanine pigment and / or a higher organic pigment, and product stability is obtained.

Claims (1)

[Claims] 1. A bolt fixing cartridge comprising a thermosetting resin contained in a crushable container and a curing agent separated from the thermosetting resin, wherein the thermosetting resin does not react with the resin. A bolt fixing cartridge containing a lake pigment, an azo pigment, a phthalocyanine pigment and / or a higher organic pigment.
