Embodiment 1

[0081] A reinforcing agent prepared from fly ash, including component A and component B, the component A is composed of the following raw materials in parts by mass:

[0082] 100 parts of unsaturated polyester resin;

[0083] Cross-linking agent: 2 parts;

[0084] White carbon black: 2.5 parts;

[0085] Dimethylaniline: 1.5 parts;

[0086] Fly ash: 450 parts;

[0087] The B component includes the following raw materials in parts by mass:

[0088] 50% benzoyl peroxide paste: 50 parts;

[0089] One or a mixture of heavy calcium, talc, kaolin: 50 parts.

[0090] The unsaturated polyester resin is MG anchor resin, the crosslinking agent is styrene, and the fly ash is 10-80 mesh.

[0091] Prepare component A and component B separately. After the preparation is complete, sample and mix component A and component B at a mass ratio of 100:2 to obtain the final product.

Embodiment 2

[0093] A reinforcing agent prepared from fly ash, including component A and component B, the component A is composed of the following raw materials in parts by mass:

[0094] 100 parts of unsaturated polyester resin;

[0095] Cross-linking agent: 0.5 part;

[0096] White carbon black: 0.5 parts;

[0097] Dimethylaniline: 0.5 parts;

[0098] Fly ash: 300 parts;

[0099] The B component includes the following raw materials in parts by mass:

[0100] 50% benzoyl peroxide paste: 50 parts;

[0101] One or a mixture of heavy calcium, talc, kaolin: 50 parts.

[0102] The unsaturated polyester resin is MG anchor resin, the crosslinking agent is styrene, and the fly ash is 10-80 mesh.

[0103] Prepare component A and component B separately. After the preparation is completed, sample and mix component A and component B at a mass ratio of 100:10 to obtain the final product.

Embodiment 3

[0105] The difference from Example 1 is that: the B component also includes 2,4-dichlorobenzoyl peroxide: 1.5 parts. Prepare component A and component B separately. After the preparation is completed, sample and mix component A and component B at a mass ratio of 100:3 to obtain the final product.

Abstract

The invention discloses a reinforcing agent prepared from fly ash, which includes component A and component B. The component A is composed of the following raw materials in parts by mass: 100 parts of unsaturated polyester resin; crosslinking agent: 0.5 ~2 parts; white carbon black: 0.5~2.5 parts; dimethylaniline: 0.5~1.5 parts; fly ash: 300~450 parts; the B component includes the following raw materials in parts by mass: 50% benzyl peroxide Acyl paste: 50 parts; one or a mixture of heavy calcium, talc, kaolin: 50 parts. Prepare component A and component B separately. After the preparation is completed, sample and mix component A and component B at a mass ratio of 100:2-10 to obtain the final product. The reinforcing agent prepared from fly ash has the advantages of simple preparation process, low cost, economic benefits, environmental protection and the ability to turn waste into wealth.

Description

technical field [0001] The invention relates to a reinforcing agent, in particular to a reinforcing agent prepared from fly ash. Background technique [0002] In coal fields, coal seams have low compressive strength, are easily broken and deformed, and are prone to cracks and large fault zones. Broken and loose surrounding rock areas and fracture-developed zones are prone to roof caving and groundwater disasters under the condition of increased dynamic pressure. Injecting polymer chemical reinforcement into the broken rock formation of the coal seam can bond the cracks and cracks together, and finally achieve the purpose of coal rock reinforcement. The existing reinforcing agents have the disadvantages of stiff slurry, insufficient flexibility, high price, low compressive strength, and poor durability. Some slurry is also toxic and will cause environmental pollution. Therefore, it is urgent to develop a low-cost and environmentally friendly reinforcement. agent. Contents ...
