Embodiment 1

[0026] The composition of cement is by weight:

[0027] Polyester unsaturated resin 1000, dimethylaniline 14, fumed silica 10, stone powder 4500,

[0028] Stone brominated diphenyl ether 150, antimony trioxide 150;

[0029] The composition of curing agent by weight is:

[0030] Water 1000, stone powder 1000, benzoyl peroxide 80, carboxymethyl cellulose sodium 300, antimony trioxide 150.

[0031] When in use, the cement: the curing agent is mixed in a weight ratio of 1:0.08 and fully stirred.

[0032] In this embodiment, the compressive strength is 60 MPa, and the initial setting time is 8-41 seconds. Its flame-retardant performance can meet the safety production requirements of underground coal mines, and at the same time, the cost is relatively low.

Embodiment 2

[0034] In this implementation, the composition of cement by weight is:

[0035] Polyester unsaturated resin 1000, dimethyl aniline 5, fumed silica 5, stone powder 4000,

[0036] Stone brominated diphenyl ether 100, antimony trioxide 100;

[0037] The composition of curing agent by weight is:

[0038] Water 1000, Stone Powder 1000, Benzoyl Peroxide 50, Carboxymethyl Cellulose Sodium 200, Antimony Trioxide 100.

[0039] When in use, the cement: the curing agent is mixed in a weight ratio of 1:0.07 and fully stirred.

[0040] The compressive strength of this embodiment is 65MPa, the initial setting time is 41-90 seconds, and its flame retardant performance can meet the safety production requirements of coal mines.

Embodiment 3

[0042] The composition of cement in the present embodiment by weight is:

[0043] Polyester unsaturated resin 1000, dimethylaniline 12, fumed silica 8, stone powder 4200,

[0044] Stone brominated diphenyl ether 130, antimony trioxide 120;

[0045] The composition of curing agent by weight is:

[0046] Water 1000, stone powder 1000, benzoyl peroxide 70, carboxymethyl cellulose sodium 250, antimony trioxide 120.

[0047] When in use, the cement: the curing agent is mixed in a weight ratio of 1:0.06 and fully stirred.

[0048] The strength of the anchoring agent in this embodiment is 75MPa, the initial setting time is 91-180 seconds, and its flame-retardant performance can meet the safety production requirements of coal mines.

[0049] The amount of curing agent to the addition of cement mainly affects the curing time of the present invention. When the addition of curing agent is large, the curing time is shortened and the strength is slightly reduced. Otherwise, the curing t...

Abstract

The invention relates the flame-retarded resin anchoring agent, comprising clay and curing agent. The clay comprises unsaturated polyester resin, dimethylaniline, white carbon black, silica powder, diphenyl ether, and antimony trioxide. The curing agent comprises water, silica powder, benzoyl peroxide, sodium carboxymethylcellulose and antimony trioxide. The invention adds fire retarding agent in clay and curing agent, so the invention has good fire-retardancy. The invention has the advantages of simple technology, and easy application.

Description

Technical field: [0001] The present invention relates to a binder, in particular to a resin widely used in coal mine underground roadway support, shaft equipment installation, building anti-seismic reinforcement, equipment base fixing, water conservancy project slope protection, underground powerhouse support and tunnel support, etc. Anchoring agent. Background technique: [0002] Resin anchoring agent, as an anchoring product, was used in coal mine underground support roadway earlier, but because of its strong anchoring force and convenient construction, it has also been widely used and promoted in other places. When used in some special occasions, such as the fixing of some equipment bases, due to the requirements for safe production, there is a requirement for the flame retardancy of the resin anchoring agent, that is, the resin anchoring agent is required to have flame retardancy. At present, the resin anchoring agent used in China is composed of two parts: cement and c...
