Description
Technical field
The present invention relates to the technical field of thermosetting powder coating, specifically a kind of pipeline anti-electrostatic fire retardant powder
Coating and preparation method thereof and high-voltage electrophoresis coatings method.
Background technology
Coal is known as black gold as the main energy sources of economic development, the exploitation of coal, exploitation to expanding economy,
Social progress provides huge power.In the exploitation of early stage coal, there is no gas drainage under suction device, without ventilation dress yet
It sets, relies solely on gravity-flow ventilation.With going deep into for exploitation, gravity-flow ventilation cannot meet safety in production needs, then occur
Forced ventilation device, to avoid using water supply in underground with the excessively high generation dust storm of dust concentration in transmission process in recovery process
And drainage arrangement, so far occur using pipeline.
In the past, metal, concrete duct is generally used to carry out underground water delivery, air-supply, extraction, conveying gas etc..Cast iron pipe,
The major defect of steel pipe be it is perishable get rusty, explosive is hurted sb.'s feelings, particular surroundings in, the corrosion of metal pipe material is extremely serious,
It is one of the main problem caused through mistake of damaging due to crushing for being badly in need of solving.Though the various performances of pipe of concrete are superior, corrosion-resistant also fine,
But density is big, and transport is laid with, installation extremely inconvenience.
Before 1997, various pipelines used by China are mostly steel pipeline.Later with the (resistance of the dual anti-material of PE
It is combustion, antistatic), dual anti-material of PVC (fire-retardant, antistatic), the dual anti-material of fiberglass (fire-retardant, antistatic) succeed in developing, promote to mould
Pipe material obtains some applications in underground.Now, the plastic conduit during China is applied to has numerous species：(1) solid wall PE hinders
Combustion, antistatic pipe；(2) solid wall PVC is fire-retardant, antistatic pipe；(3) fiberglass is fire-retardant, antistatic pipe；(4) PVC it is fire-retardant,
Antistatic winding pipeline；(5) clad steel skeleton for polyethylene tubing.But according to Market Feedback, the producer of many production plastic tubes
All be according in MT558.1-2005 standards part 2 " polyvinyl piping materials " or third portion " polychloroethylene pipes " to product
It tests, is sayed according to some experts, the two parts of MT558.1-2005 standards refer to the mechanical performance of plastic pipe
That demarcates is too low, if only promoted the use of in underground according to the requirement of MT558.1-2005 standards part 2 " polyvinyl piping materials "
Polyethylene pipe, consequence will be hardly imaginable.The reason is that：For plastic pipe, in indices, impact resistance and anti-fast
Fast cracking ability is a very important index.Because in normal conditions of use, all kinds of tubing may all there is no problem, be afraid of
Be condition variation and accident, such as：Ground subsidence, hydraulic pressure, air pressure fluctuation, the impact of especially various external force, beat,
Collision etc., this be in actual environment frequent occurrence, it is impossible to guard against.Polyvinyl chloride pipe, glass reinforced plastic pipe are all because of anti-impact
Hit intensity is too low, and accident is constantly prevented or restricted from use by many industries.Accident also repeatedly occurs for PE80 polyethylene pipes,
As Hungary's PE80 gas pipelines once crack 700m.So PE80 polyethylene pipes are only used for low-pressure line, and to add 4 times
Safety coefficient.People often have a mistaken ideas in this respect, and to increase for tubing thickness, tubing rapid crack propagation can be to avoid.
As long as tubing used does not have the ability of certain impact strength and resistance to rapid cracking in fact, the tubing of 3cm, 4cm thickness exists
It can crack in the same old way when suddenly encountering impact.This tube wall thickness that also exactly although many undergrounds are produced with plastic conduit producer at present
It is very thick, but still tube connector cracking is can't resolve, where the reason of Frequent Accidents.Clad steel skeleton for polyethylene tubing
With unique three-decker, internal layer is antistatic, fire-retardant, corrosion-resistant, wear-resisting polyethylene layer；Middle layer is enhancement layer, material
Material is wound by high-tensile steel wires circumferential direction, the anti-anti- axial load of internal pressure；Outer layer is antistatic, fire-retardant, protection polyethylene layer.
But clad steel skeleton for polyethylene tubing will pass through three-decker, more complicated, intermediate adhesion when, will also use glue, no
Environmental protection.
Underground is that common steel tube is passed through process with plastic-coated steel, a kind of special in the inside and outside layer surface coating of steel pipe
Powdery paints prepared by composite steel tube.Plastic coated composite steel pipe is suitable for -30 DEG C~120 DEG C of working environment, with other gold
The characteristics of category pipe, plastic tube, multiple tube are compared, it combines various pipelines, the intensity of existing steel pipe, and have the corrosion resistant of plastic tube
Erosion, wear-resistant, the features such as fluid resistance is small are that a kind of safety and sanitation intensity is high, the good green pipeline of adhesion strength.Plastic-coated steel
Excellent chemical resistance, water resistance and wearability can be solved because water delivery, defeated coal, buried and sour, alkali, salt are to pipeline
Corrosion, will greatly improve the service life of pipeline, service life is up to 30-50.The length of service can be according to shaft production energy
The indexs such as power, reserve factor of mine reserves and the mine reality rate of recovery calculate, and the whole nation is under unified central planning to be averagely limited to 36 years in mine active service year,
Place is average to be limited to 30 years in active service year.As it can be seen that within mine service-life, can once be thrown using powdery paints plastic-coated steel
Money, it is lifelong to be benefited.
But underground pipeline has very high fire-retardant, antistatic requirement, and the base material of plastic-coated steel coating is organic polymer
Object, since organic polymer belongs to inflammable, insulating materials, so its is fire-retardant, antistatic property is very poor, it is difficult to which it is specific to meet underground
Environmental requirement.The performance advantage of powdery paints itself, which is embodied in, to change microstructure by adding filler, to carry
Its high flame-retardant and anti-static performance.Many powdery paints manufacturers domestic at present have begun to carry out the research of this respect, but pass through
Be commonly encountered flame retardant effect reach standard require and antistatic property does not reach requirement or antistatic property reaches the fire-retardant effect of requirement
Standard requirement is not achieved in fruit；Have after exactly adding filler that resin matrix viscosity is excessively high, craftsmanship is very poor again；Also it is exactly to be formulated
Economy is bad, cost is excessively high, and product is led to problems such as not base oneself upon on the market.
