Urethane corrosion resistant coating and preparation method thereof.
Background technology
Rattan material is a kind of natural health environment-friendly material, it have not only firm but also lightly pliable and tough, can any bending characteristic,
The rattan handicraft that it is made has a succinctly bright and clear outward appearance, hard and soft and deposit, the characteristic of practicality of lying fallow, deep favored by people.
It has been covered with fine and closely woven conduit, so rattan handicraft easily absorbs moisture, and once having adsorbed too many water on the cross section of rattan material
Point, handicraft will become soft sagging, loosely organized, and easily grow mildew, addle, thus having had a strong impact on rattan
The serviceability of handicraft.Addle to rattan handicraft quality and the impact in life-span to reduce rattan material, apply on rattan material surface
Mopping film is conventional preservative treatment mode.Cn201310576524 is by using waterborne polyurethane resin and water soluble acrylic acid tree
The use ratio adjustment of fat, improves the coating performance to flexible materials such as rattan wood products for the water paint, but only by will have
The collocation of machine resinous principle is limited to the performance improvement of coating material with adjustment, and obtained water paint is on rattan handicraft surface
The paint film toughness being formed and its binding ability Shortcomings with rattan material, easily form crackle in crooked position, and then ftracture,
Coming off, being unfavorable for keeping the durability on rattan handicraft surface for the paint film, thus affecting its anti-corrosion protection to rattan handicraft
Effect.
Content of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of toughness high and rattan material fiber associativity
Rattan handicraft aqueous polyurethane corrosion resistant coating and preparation method thereof can be combined by halloysite nanotubes that are good, not easy to crack, coming off.
The present invention is achieved by the following technical solutions:

A kind of halloysite nanotubes are combined the preparation method of rattan handicraft aqueous polyurethane corrosion resistant coating, walk including following
Rapid:
(1) microcrystalline cellulose is first pressed the sulphur that solid-liquid weight adds 60-65% than 1:5-1:10 by the preparation of nano-cellulose suspension
In acid solution, 40-50 DEG C of stirring 1-3h, is subsequently adding the water terminating reaction of 6-8 times of volume, and dialyse after ultrasonic disperse 0.5-1h 2-
Then the nano-cellulose obtaining suspension ph is adjusted to 6-7 by 4d, and volume concentration to solid content is 10-12%；
(2) guar gum and aerosol-OT salt are added in the nano-cellulose suspension obtaining in (1) jointly and in
50-60 DEG C of stirring 1-2h, adjusting ph after cooling is 8-8.5；
(3) it is slowly added to 50-60 in the material that step (2) obtains with absolute ethyl alcohol after octenyl succinic acid anhydride being mixed
DEG C, 600-1000r/min stirring reaction 3-5h, control reaction ph between 8-9, reaction terminate and after cooling down, ph be adjusted to 6-7；
(4) thing that step (3) will be added after eucalyptus oil, Tea Polyphenols, bamboo vinegar and halloysite nanotubes mix and blend 1-2h to obtain
In material, 600-1000r/min stirring 0.5-1h, is then mixed with remaining raw material, obtains final product halloysite nanotubes and is combined rattan work
Skill product aqueous polyurethane corrosion resistant coating.
The invention has the advantage that
Guar gum and nano-cellulose are first carried out solution blending by the present invention, can improve the associativity of water paint and rattan material fiber
Can, reduce paint film cracking, come off, again can well with waterborne polyurethane resin crosslinking synergy, reduce external environment to rattan material
Erosion, improve surfacecti proteon effect；Using octenyl succinic acid anhydride, mixed liquor is modified, lifting water paint toughness and
Resistance to water, last compound with remaining raw materials such as halloysite nanotubes, make prepared aqueous polyurethane corrosion resistant coating antiseptic property good, tough
Property high with rattan material fiber excellent bonding performance, not easy to crack, come off, there is antibacterial, purify air simultaneously, environmental protection,
Safety and sanitation.
