Description
Technical field
The present invention relates to water paint technical field, it is anti-that more particularly, to a kind of dampproof protection against insects eat into rattan handicraft aqueous polyurethane
Rotten paint 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 eaten into by dampproof protection against insects that are good, not easy to crack, coming off.
The present invention is achieved by the following technical solutions:
