Description
Technical field
The present invention relates to technical field of paint preparation, more particularly to a kind of solvent-free elastic polyaspartic ester urea elasticity
Floor coatings.
Background technique
Current conventional use of elastic terrace material has two major classes.One kind is preformed elastic PVC roll material, and another kind of is bullet
Property polyurethane coating.It is first to brush one layer of glue on the ground when PVC roll material site operation, then directly pastes PVC roll material
It goes to complete, construct very convenient, while PVC roll material itself can make the color and decorative pattern of various beauties during fabrication,
Decorative effect is fine.But then, PVC roll material is there is also some defects, and first, the body material polyvinyl chloride of PVC roll material
There are problems that plasticity is strong, poor flexibility, feel is bad, and second, polyvinyl chloride is easy jaundice discoloration, aging, even if indoor environment
PVC roll material is also easy to turn to be yellow, and causes apparent effect to be deteriorated, especially repairing area, and the color of new and old material is seriously inconsistent,
There are splicing seams in third, construction requirement is high, splices bad easily rise and rouses delamination, after time longer (3 years), handover
The slowly aging of the hot melt adhesive of seam leads to local crimping and plays drum problem.
The two-component or moisturecuring one-component coating that Elastic polyurethane is made of the pure and mild isocyanates of polyether polyols,
Elastic effect is good, comfortable foot feeling, but this kind of material product stability is not high, the reason is that raw material in air humidity and raw material itself
Moisture content is very sensitive, is easy to cause irregular foaming, causes construction to fail, while plasticizer, steric hindrance amine in system
Matter content is very high, there is larger smell and genotoxic potential, and this kind of material is usually applied to playing field terrace, few high-quality
This kind of material can reach and meet the standard for being applied to the higher occasion of environmental friendly indoors requirement such as hospital, classroom, aisle and want
It asks.
Therefore, the prior art need further to develop.
