Embodiment 1

[0032] A method for preparing an underground anti-burst collapse air tube, the steps of the preparation method are as follows:

[0033] Step 1, mixing glue: 31 parts of paste resin, 22 parts of dibutyl ester, 10 parts of liquid chlorinated paraffin, 8.2 parts of hydrated aluminum oxide, 5.1 parts of flame retardant, and 3.9 parts of antimony trioxide in the composition and parts by weight , 1.6 parts of zinc borate, 3.2 parts of electrostatic agent, 0.2 part of rubber scarlet, 0.8 part of dibasic lead phosphite and 0.6 part of tribasic lead sulfate are made into the mortar used to prepare explosion-proof air ducts, and the powder ingredients are put into the preparation , put in the solvent and mix well, put in other aniseed materials, fully beat the rubber material, and park the rubber material for 48 hours before use;

[0034] Step 2. Inspection: Check the gray fabric first, if there are defects, it needs to be repaired by stitching, check the inner liner, and perform heat s...

Embodiment 2

[0054] A method for preparing an underground anti-burst collapse air tube, the steps of the preparation method are as follows:

[0055] Step 1, mixing glue: 25 parts of paste resin, 16 parts of dibutyl ester, 8 parts of liquid chlorinated paraffin, 6.2 parts of hydrated alumina, 4.1 parts of flame retardant, and 3.2 parts of antimony trioxide in the composition and parts by weight , 1.3 parts of zinc borate, 2.1 parts of electrostatic agent, 0.16 part of rubber scarlet, 0.6 part of dibasic lead phosphite and 0.5 part of tribasic lead sulfate are made into the mortar used to prepare explosion-proof air ducts, and the powder ingredients are put into the preparation , put in the solvent and mix well, put in other aniseed materials, fully beat the rubber material, and park the rubber material for 48 hours before use;

[0056] Step 2 to step 7 are the same as in Embodiment 1.

Embodiment 3

[0058] A method for preparing an underground anti-burst collapse air tube, the steps of the preparation method are as follows:

[0059] Step 1, mixing glue: 35 parts of paste resin, 23 parts of dibutyl ester, 11 parts of liquid chlorinated paraffin, 9.6 parts of hydrated aluminum oxide, 6.5 parts of flame retardant and 4.6 parts of antimony trioxide in the composition and parts by weight , 2.5 parts of zinc borate, 4.1 parts of electrostatic agent, 0.32 part of rubber scarlet, 0.9 part of dibasic lead phosphite and 0.8 part of tribasic lead sulfate are made into the mortar used to prepare explosion-proof air ducts, and the powder ingredients are put into it when preparing , put in the solvent and mix well, put in other aniseed materials, fully beat the rubber material, and park the rubber material for 48 hours before use;

[0060] Step 2 to step 7 are the same as in Embodiment 1.

Abstract

The invention belongs to the technical field of rubber products, in particular to a downhole cannon-hit-resistant air duct preparation method and a cannon-hit-resistant air duct. The downhole cannon-hit-resistant air duct preparation method includes the steps of step 1, rubber cement mixing; step 2, test; step 3, cloth flattening; step 4, liner connection; step 5, plastic cement painting; step 6,button riveting; and step 7, end coil installation. The step 3 specifically includes the steps of (1), cloth connecting; and (2), cloth covering; the step 5 specifically includes the steps that (1), aflat cloth is connected with a leader to be pressed flat and pressed in the right place later; (2), whether cementing grooves and cartridge heaters of a cleansing doctor and a press roll drying ovenare normal is checked; (3), the liner is inflated to two thirds size to form an air duct, and a machine is started to pull the air duct to be flat and in the right direction; (4), a heating button isstarted to heat, and air pressure, cooling rollers, temperature and speed are regulated according to the production standard of the air duct; (5), fractioning is carried out, specifically, uniform fractioning is carried out; and (6), the air duct is rolled up. The cannon-hit-resistant air duct has the advantages of high strength, tear resistance, cannon-hit resistance, light weight, attractive application and higher shock resistance capacity, and the downhole safety ventilation can be ensured.

Description

Technical field: [0001] The invention belongs to the technical field of rubber products, and in particular relates to a preparation method of an underground anti-burst collapse air cylinder and an anti-burst collapse air cylinder. Background technique: [0002] Air ducts are widely used in coal mines. At present, the air ducts used underground have low strength, poor tear resistance and impact resistance, and are heavy and not resistant to blasting, which poses serious safety hazards. Therefore, it is very necessary to design a process for preparing downhole anti-burst-resistant coating cloth and air duct and the anti-burst-abruption duct made by this process. Invention content: [0003] The first object of the present invention is to provide a preparation method of an underground anti-burst collapse air cylinder and the anti-burst collapse air cylinder made by the preparation method, the air cylinder has high strength, tear resistance, anti-burst collapse, weight The uti...
