By the polyurethane internal die paint working viscosity after the above-mentioned thinning ratio dilution is 11 ~ 13 seconds (being coated with 4 glasss 25 ℃).
Embodiment two:
The method that a kind of use one one-liquid single-component polyurethane internal die paint carries out the polyurethane-moulded articles surface colour referring to accompanying drawing 1 present method concrete steps is:
Step 1, the die temperature that will be used to make polyurethane-moulded articles are controlled between 20 ℃ ~ 60 ℃, open the polyurethane moulding mould;
Step 2, in the polyurethane moulding mould even spraying releasing agent so that after the polyurethane-moulded articles moulding, can be easy to from the polyurethane moulding mould, spin off;
Step 3, in the polyurethane moulding mould even spraying internal die paint, it is painted in order to polyurethane-moulded articles is sprayed paint, described internal die paint is an one-liquid single-component polyurethane internal die paint, described polyurethane internal die paint is diluted in 1: 4 ~ 6 ratio with butanone or acetone;
Step 4, the urethane feed liquid that cast is used to make polyurethane-moulded articles in the polyurethane moulding mould;
Wherein said urethane feed liquid is polymerized by at least a isocyanate component and at least a polyvalent alcohol in '-diphenylmethane diisocyanate (MDI), tolylene diisocyanate (TDI), polyester polyol, the polyether glycol;
Described polymerization process is for being transported to mixing section with at least a isocyanate component and at least a polyol component through the component pipeline by use distribute type gauger, mix the back and form the polyurethane reactive mixture feed liquid, this polyurethane reactive mixture feed liquid is used for preparing cellular or closely knit polyurethane-moulded articles.
Above preparation process temperature is controlled at 10 ℃ ~ 60 ℃, and Working environment humidity is controlled at≤and 65%;
Step 5, the polyurethane moulding mould that closes shake the polyurethane moulding mould then, so that urethane feed liquid wherein is even;
Step 6, treat the urethane feed liquid cooling in the polyurethane mould, after the polyurethane-moulded articles moulding, open polyurethane mould, make the polyurethane-moulded articles demoulding, obtain the polyurethane-moulded articles of moulding, and the internal die paint color even attached to molded article surface.
Polyurethane-moulded articles after painted is detected, with reference to the cross cut test method of GB-T9286-1998 paint and varnish paint film, its sticking power≤1 grade.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
1, by '-diphenylmethane diisocyanate (MDI), toluene di-isocyanate(TDI) (TDI), PEPA, PPG, The polyurethane resin that chain extender is polymerized with by using the distribute type meter with at least a isocyanate component and at least a Polyol component is transported to mixing chamber, forms polyurethane reactive mixture and prepare cellular or closely knit polyurethane through the component pipeline Moulding article is approximate at physics and chemistry such as percentage elongation, pliability, hardness, so that one-liquid single-component polyurethane internal die paint has is anti-The characteristics such as bending, adhesive force excellence.
2, butanone or acetone are as the fine solvent of polyurethane system, than the N that existing outer spray paint often uses, N-dimethyl Formamide more has quick-drying, environmental protection low toxicity, is difficult for the advantages such as moisture absorption.
3, the use technology of an one-liquid single-component polyurethane internal die paint is that to open temperature be 20 ℃ ~ 60 ℃ mould, to mould Interior evenly spraying releasing agent evenly sprays internal die paint, again because the diluent of internal die paint is butanone or third in mould Ketone, solvent is rapidly volatilization after 20 ℃ ~ 60 ℃ mold temperatures of contact, and internal die paint forms conjunctiva with mold shape in mould, Matched moulds after the cast polyurethane feed liquid shakes mould, and feed liquid begins foamable reaction, and feed liquid is because of blow pressure and mould in foaming process The tool effect of shaking is lower fully to be contacted with the internal die paint of conjunctiva with mold shape, the feed liquid complete reaction, and polyurethane-moulded articles becomes Behind the type, internal die paint is attached to polyurethane-moulded articles, and under the effect of releasing agent, internal die paint is with polyurethane moulding system The product demoulding. The outer surface of polyurethane-moulded articles is lacquer in the dry rear mold, need not other heating, does not have foaming line, feed liquid stream The phenomenon such as trace, sand hole. Polyurethane-moulded articles after painted is detected, coat with lacquer with reference to the GB-T9286-1998 paint and varnish The cross cut test method of film, its adhesive force≤1 grade.
