Abstract
A cartridge for use in fixing an anchor bolt that encludes a fluidtight constructed casing having therein a first fluidtight chamber and a second fluidtight chamber separated from the first chamber, the first chamber containing a resin composed mainly of an ester of an epoxy resin with an organic acid comprising acrylic acid, methacrylic acid or a mixture thereof, the second chamber containing a curing agent for the resin. By the use of such a cartridge in fixing an anchor bolt to a base, there can be attained a quick fixation of the anchor bolt to the base, a high adhesive strength between the anchor bolt and the base, and a high chemical resistance of the cured resin, with little or no lowering of the adhesive strength for an prolonged period of time.
Claims23
A cartridge for use in fixing an anchor bolt, comprising:
- (a) a casing having a fluidtight construction;
- (b) partitioning means disposed in said casing for forming a first and a second chamber which are fluidtight relative to each other;
- (c) a resin contained in said first chamber, said resin being substantially composed of an ester of an epoxy resin with an organic acid selected from the group consisting of acrylic acid, methacrylic acid and a mixture thereof and a reactive monomer;
- and
- (d) a curing agent for said resin component contained in said second chamber, said curing agent comprising an organic peroxide,
- said casing and said partitioning means being breakable by the action of the anchor bolt so that said resin and said curing agent are homogeneously mixed when the anchor bolt is driven into said cartridge.
A method of fixing an anchor bolt, comprising:
- (1) drilling a hole in a base;
- (2) inserting a cartridge into the hole, said cartridge comprising:
- (a) a casing having a fluidtight construction;
- (b) partitioning means disposed in said casing for forming a first and a second chamber which are fluidtight relative to each other;
- (c) a resin being contained in said first chamber, said resin being substantially composed of an ester of an epoxy resin with an organic acid selected from the group consisting of acrylic acid, methacrylic acid and a mixture thereof and a reactive monomer;
- and
- (d) a curing agent for said resin component contained in said second chamber, said curing agent comprising an organic peroxide;
- and
- (3) driving an anchor bolt into the hole so that said casing and said partitioning means of said cartridge are broken by the anchor bolt which allows said resin and said curing agent to be homogeneously mixed and to fill in spaces between the inner wall of the hole and the periphery of the bolt, which enables the anchor bolt to be fixed to the base in a short period of time, with a strong adhesive connection between the anchor bolt and the base, said strong adhesive connection having a high resistance to chemicals and water.
A curable composition, comprising:
- a resin being substantially composed of an ester of an epoxy resin with an organic acid selected from the group consisting of acrylic acid, methacrylic acid and a mixture thereof and a reactive monomer;
- and
- a curing agent for said resin component comprising an organic peroxide.
