Moreover, the waterborne polyurethane anti-corrosion paint has good waterproof, stain-resistance properties and is easy to clean.
Description
Technical field
The present invention relates to water paint technical field, particularly relate to a kind of anti-contamination rattan handicraft aqueous polyurethane corrosion resistant coating
And preparation method thereof.
Background technology
Rattan material is a kind of natural health environment-friendly material, and it has the firmest but also the most pliable and the toughest, the characteristic that can arbitrarily bend,
The rattan handicraft that it is made has a brightest and the clearest outward appearance, hard and soft and deposit, the characteristic of practicality of lying fallow, deeply favored by people.
It is covered with fine and closely woven conduit on the cross section of rattan material, so rattan handicraft easily absorbs moisture, and once adsorbs too many water
Point, artware will become soft sagging, loosely organized, and easily grow mildew, addle, thus has had a strong impact on rattan
The serviceability of handicraft.Addle on rattan handicraft quality and the impact in life-span to reduce rattan material, be coated with on rattan material surface
Mopping film is conventional preservative treatment mode.CN201310576524 is by utilizing waterborne polyurethane resin and water soluble acrylic acid tree
The use ratio of fat adjusts, and improves the water paint coating performance to flexible materials such as rattan woodworks, but only by having
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 formed and its binding ability Shortcomings with rattan material, easily form crackle at crooked position, and then cracking,
Come off, be unfavorable for keeping the paint film durability on rattan handicraft surface, thus affect its anti-corrosion protection to rattan handicraft
Effect.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of toughness height and rattan material fiber associativity
Anti-contamination rattan handicraft aqueous polyurethane corrosion resistant coating that energy is good, the most easy to crack, come off and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of anti-contamination rattan handicraft aqueous polyurethane corrosion resistant coating, it is to be prepared by the raw material of following weight parts:
Waterborne polyurethane resin 40-50, Tween-80 0.1-0.15, solid content is the nano-cellulose suspension of 10-12%
10-15, guar gum 0.3-0.5, octenyl succinic acid anhydride 0.5-1, alcohol ester 12 0.5-1, dehydrated alcohol 4-6, Kazon preservative
0.5-1, tridecafluoro-n-octyltriethoxysilane 0.3-0.5, chlorinated paraffin-52 0.05-0.1.
A kind of anti-preparation method staiing rattan handicraft aqueous polyurethane corrosion resistant coating, comprises the following steps:
(1) preparation of nano-cellulose suspension, first presses the sulfur that solid-liquid weight ratio 1:5-1:10 adds 60-65% by microcrystalline Cellulose
40-50 DEG C of stirring 1-3h in acid solution, the water being subsequently adding 6-8 times of volume terminates reaction, and dialyse after ultrasonic disperse 0.5-1h 2-
4d, is then adjusted to 6-7 by the nano-cellulose suspension pH obtained, and volume concentration to solid content is 10-12%；
(2) guar gum and Tween-80 added jointly in the nano-cellulose suspension obtained in (1) and stir in 50-60 DEG C
Mixing 1-2h, regulating pH after cooling is 8-8.5；
(3) octenyl succinic acid anhydride, tridecafluoro-n-octyltriethoxysilane, chlorinated paraffin-52 are mixed homogeneously with dehydrated alcohol
After be slowly added in the material that step (2) obtains 50-60 DEG C, 600-1000r/min stirring reaction 3-5h, control reaction pH at 8-
Between 9, pH is adjusted to 6-7 after terminating and cooling down by reaction；
(4) after being mixed with remaining raw material by the material that step (3) obtains, 600-1000r/min stirs 0.5-1h, obtains anti-contamination
Rattan handicraft aqueous polyurethane corrosion resistant coating.
The invention have 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 the cracking of paint film, come off, potentiation can be cross-linked with waterborne polyurethane resin well again, reduce external environment to rattan material
Erosion, improve surfacecti proteon effect；Utilize octenyl succinic acid anhydride that mixed liquor is modified, promote water paint toughness and
Resistance to water, last and remaining raw material is combined, and makes the aqueous polyurethane corrosion resistant coating antiseptic property prepared good, and toughness is high and rattan material is fine
Dimension excellent bonding performance, the most easy to crack, come off, there is good water-fast, contaminated resistance simultaneously, it is easy to cleaning.
