Embodiment 1

[0027] The cement consists of parts by weight: polyester unsaturated resin 1000, dimethylaniline 14,

[0028] Fumed silica 10, stone powder 4500, acetylene carbon black 60;

[0029] The composition of the curing agent in parts by weight is: water 1000, stone powder 1000, benzoyl peroxide 80,

[0030] Sodium carboxymethyl cellulose 300, acetylene carbon black 60.

[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 antistatic performance can meet the needs of underground coal mines and occasions with special antistatic requirements, and the cost is low.

Embodiment 2

[0034] The cement consists of parts by weight: polyester unsaturated resin 1000, dimethylaniline 5,

[0035] Fumed silica 5, stone powder 4000, acetylene carbon black 30;

[0036] The curing agent consists of parts by weight: water 1000, stone powder 1000, benzoyl peroxide 50,

[0037] Sodium carboxymethyl cellulose 200, acetylene carbon black 30.

[0038] When in use, the cement: the curing agent is mixed in a weight ratio of 1:0.07 and fully stirred.

[0039] In this embodiment, the compressive strength is 65MPa, and the initial setting time is 41-90 seconds. Its antistatic performance can meet the needs of underground coal mines and occasions with special antistatic requirements.

Embodiment 3

[0041] The cement is composed of parts by weight: polyester unsaturated resin 1000, dimethylaniline 12,

[0042] Fumed silica 8, stone powder 4200, acetylene carbon black 50;

[0043] The composition of the curing agent in parts by weight is: water 1000, stone powder 1000, benzoyl peroxide 70,

[0044] Sodium carboxymethyl cellulose 250, acetylene carbon black 50.

[0045] When in use, the cement: the curing agent is mixed in a weight ratio of 1:0.06 and fully stirred.

[0046] The strength of the anchoring agent in this embodiment is 75MPa, and the initial setting time is 91-180 seconds. Its antistatic performance can meet the needs of underground coal mines and occasions with special antistatic requirements, and at the same time, the cost is low.

[0047] 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. ...

Abstract

The invention relates the electrostatic resistance resin anchoring agent, comprising clay and curing agent. The clay comprises unsaturated polyester resin, dimethylaniline, white carbon black, silica powder, and acetylene black. The curing agent comprises water, silica powder, benzoyl peroxide, sodium carboxymethylcellulose and acetylene black,. The invention adds acetylene black in clay and curing agent, so the invention has good antistatic property. The invention can meet the request for static electricity at many producing stations. The invention has the advantages of simple technology and easy operation.

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 fixation of the base of precision machine tools, due to the requirements for safe production, there are strict requirements on the antistatic performance of the resin anchoring agent. It is required that the product should not be used during use. Generate static sparks. [0003] At present, the resin anchoring agent...
