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 preparation 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 preparation 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, 10-15 parts of chlorinated paraffin, 2-7.5 parts of amine type accelerator, 3-5 parts of curing agent, fire retardant A
80-100 parts, 3-5 parts of antistatic agent.
Wherein the unsaturated polyester resin be m-phthalate unsaturated polyester resin, metaphenylene unsaturated polyester resin and
The mixture of one or more of terephthalic unsaturated polyester resin.
The curing agent is cumyl peroxide, bis- (tert-butylperoxyiso-propyl) benzene of 1,1-, tert-butyl cumyl peroxide
The mixture of one or more of base peroxide, bis- (tert-butyl peroxy isopropyl) benzene.
The amine type accelerator is the dilute tetramine of three second, the dilute triamine of diethyl, m-phenylene diamine (MPD), salicyl dimethylamine, benzyl
Dimethylamine, N, accelerine, the mixture of one or more of dimethylamino bismethane.
The mixture that the fire retardant A is magnesium hydroxide and red phosphorus mass ratio is 10:1.
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 preparation 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, chlorination is first added in proportion
Paraffin, curing agent, are mixed thoroughly, and fire retardant is then added, and are mixed thoroughly, are subsequently added into antistatic agent and are mixed thoroughly, are eventually adding promotor and are mixed thoroughly,
Up to inner layer tube wall material；
(2) by inner layer tube wall application of material on tubing machine die pipe, thick 1-2mm；
(3) prepare unsaturated polyester resin adhesive: quantitatively weighing unsaturated polyester resin, in proportion first be added chlorinated paraffin,
Curing agent is mixed thoroughly, adds 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 chlorinated paraffin in formula, chlorinated paraffin is the chlorinated derivatives of paraffin hydrocarbon, has low volatility, resin can be reduced after addition
In solidification process, the loss of solvent styrene reduces environmental pollution and the influence to worker health；The increasing of chlorinated paraffin simultaneously
Add, the dispersion effect of fire retardant in the feed can be improved.The curing agent and promotor of use, molecular weight is higher, can room temperature it is solid
Change, compared with ethylenediamine, toxicity is low, and heat-resisting, resistance to chemical reagents, solidfied material shrink small, anti-impact, bending resistance, heat shock resistance good electrical property.
The mixture that magnesium hydroxide and red phosphorus mass ratio are 10:1, flame retardant effect is more preferable than aluminium hydroxide, and dosage is lower, can effectively reduce
The problems such as causing product mechanical properties decrease and product surface to be cracked due to solid powder addition.
