Description
Technical field
The present invention relates to special fibre Material Fields, relate in particular to a kind of mining gas draining tube, simultaneously also
It is related to the production method of the mining gas draining tube.
Background technique
Metal tube, glass fiber reinforced plastic expects pipe use in the extraction of coal mine gas gas and municipal works plumbing, have
The history of many years.The defect of metal tube and glass fiber reinforced plastic expects pipe because of its own: perishable, get rusty, fouling, leakage, blocking, intensity
The disadvantages of low, easy to aging, inflammable, antistatic is weak, can not meet the requirement of underground coal mine use environment.
China is that coal production big country, gas are always the principal element of safety of coal mines in the world, increases and develops suitable coal
The mining gas discharging polyester fiber multiple tube used under mine environmental condition, meets coal mine production safety and needs to be the task of top priority.
The own patent of the applicant, China Patent Publication No. CN102506239A disclosed one on 06 20th, 2012
Kind mining gas draining tube, since in solidification process, the loss of solvent styrene is easy environmental pollution and worker health
Impact；The curing agent and promotor ethylenediamine toxicity of use are higher, heat-resisting, resistance to chemical reagents, anti-impact, bending resistance, heat-resisting punching
It is fine for hitting electrical property not；Fire retardant aluminium hydroxide dosage is higher, solid powder add and cause product mechanical properties decrease and
The problems such as product surface is cracked.
Summary of the invention
The purpose of the present invention is to provide a kind of mines corrosion-resistant, intensity is high, non-aging, good flame resistance, antistatic are strong
With methane gas releasing pipe.
Another object of the present invention is to provide the production methods of the mining gas draining tube.
A kind of mining gas draining tube of the invention, the raw material including following parts by weight:
100 parts of unsaturated polyester resin, 5-8 parts of amine type accelerator, 3-5 parts of curing agent, 70-90 parts of fire retardant A, antistatic agent
3-5 parts.
Wherein the unsaturated polyester resin is m-phthalate unsaturated polyester resin and bisphenol A epoxide resin mass ratio is
The mixture of 5:1.
The mixture that the fire retardant A is magnesium hydroxide and red phosphorus mass ratio is 10:1.
The curing agent is methyl ethyl ketone peroxide, benzoyl peroxide, cyclohexanone peroxide, the tertiary fourth of benzoyl peroxide
A kind of mixture with cycloalkanes cobalt acid or cobalt iso-octoate, mixed proportion 1:1 in ester.
The amine type accelerator is one of hexamethylene diamine, diethylaminopropylamine, diethylenetriamines, triethylamine or two
Kind or more mixture.
The antistatic agent is that conductive channel black, conductive furnace blacks and acetylene black superconduct furnace blacks, high electric conductivity
One of furnace blacks.
A kind of production method of above-mentioned mining gas draining tube, comprising the following steps:
(1) it prepares the fire-retardant and anti-static material of inside and outside parietal layer: quantitatively weighing unsaturated polyester resin, solidification is first added in proportion
Agent is mixed thoroughly, and fire retardant is then added, and is mixed thoroughly, is subsequently added into antistatic agent and is mixed thoroughly, is eventually adding promotor and is mixed thoroughly to get internal layer
Pipe wall material；
(2) by inner layer tube wall application of material on tubing machine die pipe, thick 1-2mm；
(3) it prepares unsaturated polyester resin adhesive: quantitatively weighing unsaturated polyester resin, curing agent is first added in proportion, mix
It is even, add promotor, then mix thoroughly to obtain the final product；
(4) unsaturated polyester resin adhesive is replaced with medium alkali fiber cloth in coverage is bonded on tubing machine die pipe
On layer material, is determined according to the pressure that caliber and pipe are born, until reaching the thickness of requirement, make pipe middle layer；
(5) finally on intermediate layer material, then apply step 1 preparation material 1-2mm thickness to get.
Compared with prior art, the present invention having apparent beneficial effect, as can be known from the above technical solutions: the present invention exists
Increase bisphenol A epoxide resin in formula, the loss of the solvent styrene of m-phthalate unsaturated polyester resin can be reduced, reduces environment
Pollution and the influence to worker health；Due to bisphenol A epoxide resin have good physical mechanical property, chemical resistance,
Electrical insulation properties have good adhesive property to multiple materials such as metal, glass, ceramics, and bisphenol A epoxide resin is added can be big
The big cohesive force increased between reinforcing fiber and resin, increases the intensity of pipe, hardness.Curing agent: per-compound and cobalt acid
Class curing agent is used cooperatively, and than individually using per-compound class curing agent curing time shorter, effect is more preferable, for double groups
Divide the solidification effect of resin more preferable.Promotor: molecular weight is high, normal temperature solidified, and compared with ethylenediamine, toxicity is low, heat-resisting, drug resistance
Moral character, solidfied material shrink small, anti-impact, bending resistance, heat shock resistance good electrical property.The mixing that magnesium hydroxide and red phosphorus mass ratio are 10:1
Object, flame retardant effect is more preferable than aluminium hydroxide, and dosage is lower, can effectively reduce and cause product mechanical property since solid powder adds
The problems such as energy decline and product surface are cracked.The addition of red phosphorus, it is easier to disperse in resin, compared with aluminium hydroxide, the group of being not easy
The problems such as gathering, product caused to be cracked.
