Problems solved by technology

At the same time, some areas with complex geological conditions, especially underground engineering, water conservancy and hydropower projects, develop in the direction of large diameter, large anchor depth, and easy application of prestress. Some engineering construction uses cement mortar pumping for anchoring, but its strength increases. slower than anchors
The existing resin anchoring agent cannot meet the requirements of long construction time and high strength requirements due to its fast gelation time (8s-10min) or low compressive strength (<40MPa, which does not meet the technical requirements of MT146.1-2002).

Abstract

The invention discloses a super-slow resin anchoring agent. Unsaturated polyester resin is adopted; one or a plurality of tertiary amine accelerant, quinhydrone, naphthaquinone or other polymerization inhibiting stabilizer with similar functions, and other chemical assistant and filler are added in resin production or later process to be mixed into resin cement; initiator (solidifying agent) is one or a plurality of dibenzoyl peroxide or other similar peroxide, pasty or powdered solidifying agent diluted by water, stone powder or other inert materials; and the mixture is packaged into scrolls by a diplopore film bag or packaged by a barrel or other packaging modes. In the formulation, the super-slow resin anchoring agent produced through fine adjustment, which has gelling time of between 10 and 180 minutes and compressive strength not less than 40MPa, so the super-slow resin anchoring agent can meet special requirements of long engineering construction, high strength requirement, and the like.

Description

Technical field: [0001] The invention relates to an anchoring agent, in particular to an ultra-slow resin anchoring agent. Background technique: [0002] Resin anchoring agent is a polymer bonded anchoring material composed of synthetic resin, filler and chemical additives developed and produced according to the principle of bolt support and technical requirements. It is matched with rods of different materials and specifications to form multiple Various forms and uses of resin anchor rods and resin anchor bolts. It is suitable for mines, underground engineering and slopes, anchor shotcrete support, mine shaft equipment installation, building component connection and reinforcement, equipment foundation anchorage, etc. [0003] With the development of anchor support and the innovation of construction tools, the overall trend of resin anchoring agent is to small diameter, fast curing and full anchoring. At the same time, some areas with complex geological conditions, especia...
