Problems solved by technology

[0005] 1. After curing, it will gradually turn yellow, and the most important thing is that it will produce fine cracks. The system requires harsh reaction conditions, but it is not easy to achieve in practice, so the resin anchoring agent is often not cured enough, which directly leads to the strength of the resin anchoring agent (compression resistance, resistance Tensile strength) can not reach the maximum, curing is not complete
[0006] 2. Under this accelerated initiation system, the gel time design range of the resin anc

Abstract

The invention discloses a resin anchoring agent for an initiation system. In the invention, cobalt octoate or cobalt naphthenate is used as a promoter, or cobalt octoate or cobalt naphthenate and tertiary amine promoters are mixed to form a compound promoter. A novel initiator is hydroperoxides, particularly methyl ethyl ketone peroxide and cyclohexanone peroxide. In the invention, resin anchoring agent of all models can be designed and produced, the longest gelation time can be adjusted to 10 hours or even a longer time, the curing can be continued later on when the curing of a reaction is inadequate, the curing degree is high, and the final strength is high. Moreover, the period of validity of the resin anchoring agent can be prolonged for over 1 time.

Description

technical field [0001] The invention relates to a resin anchoring agent, in particular to a resin anchoring agent for promoting an initiation system. Background technique [0002] Using unsaturated polyester resin as binder, limestone powder as reinforcing material, and a suitable accelerator-initiating system, the resin cement produced can obtain high strength and fast curing effect. Pack this kind of cement into a drug roll with polyester or composite film, and pack it separately from the curing agent (including initiator), which is the resin anchoring agent. It is widely used in coal wall and roof support of coal mines, roof support of tunnels, shaft installation and seismic reinforcement of buildings, etc. [0003] At present, in the traditional formula design of all anchoring agents on the market, the initiators in the accelerated initiation system are organic peroxides, such as benzoyl peroxide, 2,4-dichlorobenzoyl peroxide, etc. The agent is a tertiary amine acceler...
