Description
Technical field
The present invention relates to water paint technical field, it is poly- that more particularly, to a kind of hydrolytic collagen is combined rattan handicraft aqueouss
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, artware 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 hydrolytic collagen that is good, not easy to crack, coming off.
The present invention is achieved by the following technical solutions:
A kind of hydrolytic collagen is combined rattan handicraft aqueous polyurethane corrosion resistant coating, and it is by the raw material system of following weight parts
:
Hydrolytic collagen 0.5-1, solid content is the nano-cellulose suspension 10-15 of 10-12%, guar gum 0.3-0.5, aqueouss
Polyurethane resin 40-50, octenyl succinic acid anhydride 0.5-1, dehydrated alcohol 4-6, Kazon preservative 0.5-1, boric acid 0.1-0.15,
Trehalose 0.1-0.15, terpenes emulsion 1-2, nano-silicon nitride 0.5-1.
A kind of hydrolytic collagen is combined the preparation method of rattan handicraft aqueous polyurethane corrosion resistant coating, walks including following
Rapid:
(1) Microcrystalline Cellulose is first pressed the sulfur 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, hydrolytic collagen and boric acid are added in the nano-cellulose suspension obtaining in (1) and in 60- jointly
80 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 dehydrated alcohol after octenyl succinic acid anhydride being mixed homogeneously
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) after the material obtaining step (3) is mixed with remaining raw material, 600-1000r/min stirring 0.5-1h, obtains final product hydrolysis glue
Former albumen is combined rattan handicraft aqueous polyurethane corrosion resistant coating.
The invention has the advantage that
Guar gum, hydrolytic collagen and nano-cellulose are first carried out solution blending by the present invention, can improve water paint and rattan
The binding ability of material fiber, reduces the cracking of paint film, comes off, again can crosslinked potentiation, minimizing with waterborne polyurethane resin well
The erosion to rattan material for the external environment, improves surfacecti proteon effect；Using octenyl succinic acid anhydride, mixed liquor is modified, lifting
The toughness of water paint and resistance to water, last and remaining raw material is combined, and makes 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, paint film high resilience, compactness are good, and smooth surface is put down
Whole, presentation quality is good.
