Abstract
The invention relates to a preparation method of a delayed coagulation type resin bolting anchoring agent. A material playing a role in bond-anchorage is known as the anchoring agent; the resin bolting anchoring agent is packaged into a roll shape through separating resin-bonded mastic from hardener. The resin bolting anchoring agent mainly comprises two components including the resin-bonded mastic and the hardener, wherein the resin-bonded mastic and the hardener are mixed uniformly in a proportion when in use, so that a rod body can be bonded with coal to be anchored after mixing. The resin-bonded mastic is mainly formed by unsaturated polyester resin, polymerization inhibitor, accelerator and inorganic filler; and the hardener is mainly formed by mixing initiator, solvent and inorganic filler. The delayed coagulation type resin bolting anchoring agent has the following characteristics that (1) the gel time t is longer, and is greater than or equal to 4h and is less than or equal to 24h, and the requirement of the delayed coagulation type resin bolting anchoring agent is met; and (2) the anchorage force is larger, and the whole anchor is greater than or equal to 40MPa.
Description
Technical field:
The present invention relates to a kind of Anchor Agent that is applied in the coal mine tunnel top board anchorage cable anchoring, be applicable to specifically the preparation method of the retardation setting type resin anchor Anchor Agent of tension dispersed anchor cable anchor structure.
Background technology:
At present, the superficial part resource in the many collieries of China is petered out, and mine progresses into deep mining, and anchor cable has become a requisite part in deep-well tunnel supporting construction.But the anchor failure phenomenon happens occasionally in the supporting practice stream line, and roof fall accident is caused in a plurality of mining areas at home in recent years, serious threat miner's life security.To the observation in tunnel, mining area, find that the interior anchor-hold of anchor cable is seriously the major cause that interior anchor lost efficacy lower than its breaking force according to for many years.What generally use in supporting at present is pulling force concentrated anchor cable, the type anchor cable produces serious stress concentration at interior anchoring initiating terminal, cause the Progressive failure of anchoring body depth direction, finally cause interior anchor to lose efficacy, cause serious threat for colliery roadway support and safety.
For overcoming pulling force concentrated anchor cable defective in use, improve the anchor cable utilization ratio, guarantee the security of coal mining, work out a kind of novel tension dispersed anchor cable anchor structure.Tension dispersed anchor cable adopts the Anchor Agent of two kinds of different anchoring properties, wherein a kind of is the rapid resin Anchor Agent that uses in the market, another kind be need to longer set time ultra-slow resin anchoring agent, thereby realize the effect of gradation anchoring by the difference of both set times, to reach the purpose of improving anchor section strained condition in anchor cable, improve the anchoring property of anchor cable, thereby improve stability and the security of colliery tunnel support, and have higher economic benefit.
The development of retardation setting type Anchor Agent at present mainly concentrates on the mortar class, solidify delay time and can reach 20h, but such Anchor Agent anchor force is lower, can not satisfy the requirement of the high anchor force of Mine anchorage cable.And the used resene Anchor Agent in colliery set time the longest only 8min, can not satisfy the requirement of tension dispersed anchor cable anchor structure, for realizing the anchor structure of tension dispersed anchor cable, in the urgent need to developing a kind of novel slow setting resin anchoring agent.
Summary of the invention:
The deficiency and the defective that exist in actual applications for existing resin anchoring agent, the invention provides a kind of retardation setting type resin anchor Anchor Agent, thereby realize the effect of gradation anchoring by the difference of Anchor Agent set time, to reach the purpose of improving anchor section strained condition in anchor cable, improve the anchoring property of anchor cable, thereby improve stability and the security of colliery tunnel support.
Retardation setting type resin anchor Anchor Agent is comprised of resin-bonded mastic and solidifying agent two portions, and wherein the weight of resin-bonded mastic is 601.32Kg～923.20Kg, and the weight of solidifying agent is 7.7Kg～38Kg; Concrete preparation manipulation step is as follows:

(2) preparation of solidifying agent
Initiator 4.50～14Kg
Solvent 1.20～6Kg
Mineral filler 2～18Kg
Described initiator is methylethyl ketone peroxide; Solvent is dimethyl phthalate; Mineral filler is to be mixed by weight 200:1 by talcum powder and white carbon black; Initiator and the mineral filler of described weight are joined in solvent, stir, obtain solidifying agent;
When (3) using, the solidifying agent of the resin-bonded mastic of described weight and described weight is mixed namely obtain retardation setting type resin anchor Anchor Agent.
Retardation setting type resin anchor Anchor Agent of the present invention has the following advantages:
(1) gel time t is longer, and 4h≤t≤24h meets the requirement of retardation setting type resin anchor Anchor Agent;
(2) anchor force is larger, full anchor 〉=40MPa; The retardation setting type Anchor Agent satisfies long, the particular requirement such as requirement of strength is high of engineering construction time.
Research by retardation setting type resin anchor Anchor Agent and then propose novel pulling force decentralized anchor structure can significantly improve stability and the security of tunnel roof bolting with bar and wire mesh, reduces the roadway support material cost.This has great importance to mining science state of the art and the security level of enriching China's Roadway Support Technology, improving China.
