Abstract
The invention relates to a method for producing UV resin by taking urea and formaldehyde which are base materials in the field of coal chemical industry as main raw materials. The resin is small in smell and excellent in yellowing performance, thereby being capable of being taken as base resin to be widely used in bottom paint of UV woodenwares and UV paint of PVC buckle plates.
Description
Technical field
The present invention relates to one kind utilizes urea, the basestocks of formaldehyde --- coal chemical technology are the method that primary raw material manufactures UV resins,
The resin smell is little, xanthochromia excellent performance, can be widely used in UV woodenware bottom surface paint and PVC buckles UV paints as matrix resin.
Background technology
Traditional solvent wood coatings, it is positive due to containing substantial amounts of solvent VOC maximum discharges, larger pressure being caused to environment
Solvent-free environment-protection woodwork coating changes.Wherein there is prospect the most with UV coating, apply more than 80% in plane base material at present
Instead of traditional solvent based coating.But UV coatings industries have the defect of itself:One is that UV coating is not also accomplished very in isomery face
Good solidification, this part, traditional coating may develop towards water paint.Two is that the surface effect that UV coating is applied also does not reach biography
System solvent based coating applies effect, and this part, traditional solvent-borne coating still retains.Three is UV coating resins raw material sources ratio
Relatively narrower --- nearly all it is fine chemical product, price is high, and this causes portions of client it is contemplated that price factor is still selected
Select solvent based coating.For example show the maximum UV resins of consumption, epoxy acrylate is closed by 25% acrylic acid and 75% epoxy resin
Into.Epoxy resin belongs to fine chemistry industry, and synthesis technique is complicated, and price is high.
If the bulk raw material of UV resins is bypassed into fine chemistry industry and joint petrochemical industry, gas chemical industry or coal carbonization
Then UV resin raw materials price has a larger range of decrease to work.
In coal chemical industry, urea is cheap.Gone to produce UV resins, UV resin valencys as main raw material(s) with urea-formaldehyde
Lattice have the larger range of decrease.UV coating and traditional solvent based coating compare then without price inferior position, further promote traditional coating
To UV development.
Urea-formaldehyde UV resins, as other UV resins a performance requirement and index are had to comply with.Due to using
Formaldehyde is raw material, and paint film release formaldehyde naturally becomes the emphasis of control;Formaldehyde is added, and smell can be caused to increase, if not
Control free formaldehyde, then smell is pungent, and smell is control object.
1st, resin outward appearance:As clear as crystal mechanical impurity, the slightly yellow thick liquid of color
2nd, color:≤1#(Fe-Co colorimeters)
3rd, storage stability:80 DEG C, 72 hours(Sealing experiment), increase s.mPa/25 DEG C of viscosity≤1000.
4th, free formaldehyde:≤ 0.5g/kg, quotes harmful substance limit in the solvent-based adhesive of GB18583-2001.3.1 tables 1
Value.
5th, dry film formaldehyde:≤ 40 mg/100g quote GB18585-2001《Harmful substance limit in indoor decorating and refurnishing materials
Amount》, solid wooden compound floor, B classes
6th, dry film smell:With net taste light trigger, separately made dry film is heard resin and is applied at 15-30 μm, directly in white ceramic tiles
Film has no irritating odor.
