Resin special for anchoring agent and preparation method thereof

Abstract

The invention discloses a resin special for an anchoring agent and a preparation method thereof. The resin is mainly prepared from terephthalic acid, fumaric acid, abietic acid, maleic anhydride, oxalic acid, glycerol, diglycol, a catalyst, a polymerization inhibitor, a stabilizing additive and styrene according to a certain proportion. A special resin which is most suitable to serve as an anchoring agent product is provided through means such as the adoption of a reasonable production process design formula, the adding of some chemical additives and the like. The gel time of the resin is short and is slightly affected by the temperature, the final curing strength is high, the early strength is quickly developed, the storage stability is high, the resin has high adhesion to mountain flourand has high adaptability to the mountain flour, and the doping amount of the mountain flour is large; and the cost is low, and each ton of the resin is 10 to 20 percent cheaper than each ton of an ordinary unsaturated resin.

Description

technical field [0001] The invention belongs to the technical field of unsaturated polyester resin, and in particular relates to an unsaturated polyester resin used as an anchoring agent and a preparation method thereof. Background technique [0002] Anchoring agent is the most widely used adhesive anchoring material in modern times. It is composed of high-performance unsaturated polyester resin and curing agent, accelerator, filler and other chemical additives. The application of resin anchoring agent in coal mines in my country has a history of more than 50 years. With the country's high attention to coal mine safety and the continuous increase in the amount of anchoring agent, the scope of application continues to expand, and higher and higher requirements are put forward for the performance of anchoring agent. , There are many problems in using traditional general-purpose unsaturated resin as anchoring agent products: such as the short storage period of anchoring agent, i...

The application of resin anchoring agent in coal mines in my country has a history of more than 50 years. With the country's high attention to coal mine safety and the continuous increase in the amount of anchoring agent, the scope of application continues to expand, and higher and higher requirements are put forward for the performance of anchoring agent. , There are many problems in using traditional general-purpose unsaturated resin as anchoring agent products: such as the short storage period of anchoring agent, it can only be stored for 3-6 months at room temperature, especially in summer, some storage periods are less than 2 months The cement part of the anchoring agent will harden; the gel time of the anchoring agent is slow; the gel time is greatly affected by the temperature; the final strength after curing is low, and the early strength development is also relatively slow. The resin has poor adaptability to stone powder and poor adhesion. It is also poor, the amount of stone powder is low, the high temperature resistance is poor, and the price of resin is also high.
