Description
Technical field
The present invention relates to a kind of coating of protection aerostatics envelop materialses and its preparation method and application.
Background technology
Aerostatics utricule protective coating is referred to for the coating with protective effect on aerostatics envelop materialses, is broadly divided into
Aerostatics utricule hinders helium coating and aerostatics utricule protective coating.Aerostatics generally refer to proportion be lighter than air, rely on air
The aircraft of buoyancy lift-off.In electronics and military civil area, typically not by fire balloon stroke in the range of aerostatics.Additionally, empty
Between dirigible not necessarily rely on buoyancy.In addition to military, large-scale civilian aerostatics can be also used for traffic, transport, entertain, relieving the people in stricken areas,
Movies-making, scientific experiment etc..The particularity such as helium rejection rate, wearability, the resistance to ag(e)ing of aerostatics utricule protective coating
Can ensure that aerostatics is capable of the working life of smooth working, the safety of aerostatics staff and aerostatics, to floating
Device completes for a long time task and plays an important role.
The aerostatics envelop materialses of China's independent research are mainly made up of aramid fiber, its have helium barrier it is relatively low,
The shortcomings of ageing-resistant performance is poor, is unable to reach the technical requirements of heaven work on the premise of protective coating is not coated by.By in
The aerostatics envelop materialses of Aerospace Science and Industry Corporation of state independent research, its helium rejection rate is relatively low, it is impossible to when ensureing that dirigible is in long
Between normal operating conditions；Ultraviolet aging resistance is poor, causes aerostatics service life shorter, current domestic existing common resistance to old
Changing coating its wearability cannot match with flexible aramid fiber base material, in addition external blockade on new techniques and dependence in the field
The enormous expenditure that import is caused, be badly in need of it is a kind of can Long-Time Service, possess higher helium barrier, wearability, resistance to ag(e)ing
New aerostatics utricule protective coating, to reduce the R＆D costs and maintenance cost of aerostatics as far as possible, and it is stable to lift its
Property.For improving domestic aerostatics job stability and increasing the service life, tool is of great significance.
The content of the invention
The technical problem to be solved is to provide one kind and is mainly coated on aerostatics envelop materialses surface to be lifted
The polyurethane series aerostatics utricule that its helium barrier, resistance to ag(e)ing and anti-wear performance and aerostatics envelop materialses match is protected
Shield coating.
The technical scheme is that, there is provided a kind of coating of protection aerostatics envelop materialses, the coating is by component A and B
Component is mixed with and forms, and component A is 100 with the mass ratio of B component:10～15；
Wherein, by weight, component A includes consisting of：
Polyurethane resin：45～55 parts
Titanium dioxide：10～15 parts
Defoamer：0～1 part

B component is：Polyamide curing agent.
Preferably, the polyurethane resin in component A is NY-35 type polyurethane resins.
Preferably, the titanium dioxide in component A is rutile-type 2377# titanium dioxides.
Preferably, the diluent in component A is that mass ratio is 4:1 dimethylbenzene and the mixed liquor of n-butanol.
Preferably, the dispersant in component A is the solution with acid base co-polymer.
Preferably, the defoamer in component A is the diisobutyl ketone solution of polysiloxanes.
Preferably, the defoamer in component A is BYK-066N type defoamers.
The technical problem further to be solved of the invention is to provide one kind and can strictly control coating layer thickness, and then limits
The unit area of aerostatics envelop materialses increases weight and coating structure is uniform, performance is higher, easy construction coating processes.For this purpose,
The present invention provides the preparation method of above-mentioned coating and its specific application.
The present invention further provides the preparation method of described coating, comprises the following steps：
(1) 45～55 parts of polyurethane resins, 10～15 parts of titanium dioxides are added in material-compound tank, 0～1 part of dispersant, 0～1
Part defoamer, stirring, then bead is added thereto to, and 2～4h is disperseed under 2500～3500r/min, obtained with filter-cloth filtering
White colorant, is designated as component A；
(2) component A and B component are pressed into 100:10～15 mass ratio is mixed, and is stirred, and obtains final product protection aerostatics
The coating of envelop materialses.
Above-mentioned preparation method is more specifically comprised the following steps：(1) 45～55 parts of polyurethane resins are added in material-compound tank,
And add 10～15 parts of titanium dioxides, 0～1 part of dispersant, 0～1 part of defoamer, with the rotating speed stirring 25 of 450～550r/min～
35min, then be added thereto to the 80～120g of bead of a diameter of 2～3mm, disperse 2 at a high speed under 2500～3500r/min～
4h, with filter-cloth filtering white colorant is obtained, and is designated as component A；

15～30min is mixed, the coating of protection aerostatics envelop materialses is obtained final product.
Further, the coating for above-mentioned preparation method being obtained is using 6 μm of coating line bar coatings to aerostatics utricule base material
On, treat that paint solidification is dried, obtain final product aerostatics envelop materialses protective coating.
Especially, it is emphasized that the coating line bar gauge lattice that the present invention is used are 6 μm, if coating thickness is higher than 6 μm, can cause to apply
Film thickness is excessive, causes the weightening of base material unit area overweight.
Coating of protection aerostatics envelop materialses of the present invention and preparation method thereof has the advantages that：
(1) aerostatics envelop materialses protective coating of the present invention can film-forming at room temperature, reality is completed in 24h
Dry, its drying mode needs the drying mode of heating, drying due to conventional urethane elastomer, is adapted to different shape, chi
Very little base material；
(2) aerostatics envelop materialses protective coating of the present invention is at room temperature after film-forming, paint film appearance is homogeneous,
Stable, almost free of surface defects, preferably, paint film can realize normal temperature rapid curing to glossiness, and adhesive force is preferably, wear-resisting after solidification
Property is excellent；
(3) present invention is based on special polyurethane (NY-35 type polyurethane resins), and in addition appropriate titanium dioxide is carrying
The covering power of coating is risen, the aerostatics envelop materialses protective coating of preparation can match with aerostatics utricule base material pliability, greatly
Amplitude lifts its helium barrier, coats the base material of the protective coating after rubbing test is undergone, though its helium barrier is
Decline, but still conform to technical requirements.
Therefore, the aerostatics envelop materialses protective coating that prepared by this method rapid curing can be dried at normal temperatures, film
With excellent helium barrier and good wearability, resistance to ag(e)ing, the protection requirement of aerostatics envelop materialses is met.

Why the helium rejection rate of envelop materialses is improved, and is because being coated with after this protective coating, envelop materialses
On hole filled up, and then material leakage helium rate decline；After being subjected to 100 rubbings, the leakage helium rate of envelop materialses rises,
It is because during rubbing, envelop materialses protective coating structure is destroyed, envelop materialses surface folding increases, interlayer hole
Gap increases, and then fault in material increases, and the barrier of helium is declined, but because the coating flexibility for coating is preferable, is undergoing
After 100 rubbings, the pliability for keeping matching with base material is remained to, therefore the destroyed degree of coating structure is less, still to helium
Keep good barrier.It is reported that, the base material of the protective coating is not coated after 100 rubbings are undergone, its leakage helium rate will
