Description
Technical field
The present invention relates to a kind of polyurethane coating, relates in particular to a kind of solvent-free, Self-leveling polyurethane floor coatings.
Background technology
With the continuous development of modern economy and science and technology, what industrial mill floor was put forward the more to open the more high will
Ask, for example, ground it is attractive in appearance, do not play dirt, be wear-resistant, resistance to heavy impact, acid and alkali-resistance, oil resistant etc., this is not only to improve working environment will
Ask the guarantee of even more product quality.At present both at home and abroad, many workshop ground are all decorated and protected using floor coatings
Shield, is widely used in the industries such as electronics, precision instrument, vehicle, machinery, chemical industry, medicine, food.
The requirement that floor coatings are generally divided into primary coat, middle painting and face painting opposite painting by the effect in painting design relatively will
It is higher.Face figure not only plays the performance effect of color, is even more directly contact mechanical wear and impact and the corruption of chemicals
Erosion, it is desirable to there is preferable combination property, the floor coatings for being now widely used in face figure are solvent type epoxy-polyurethane coatings
With solvent-free epoxy self-leveling coating.
Although solvent type epoxy polyurethane coating has, adhesive force is strong, and pliability is good, wear-resistant, the corruption of resistance to general chemicals
The advantages that erosion, less expensive.But this terrace one-pass film-forming thickness generally at 100 μm once, contain more solvent
And TDI, not only the environment of the health and surrounding of production and construction worker is damaged, and solvent-borne type volatilization and one kind
The waste of resource.
Solvent-free epoxy self-leveling coating uses the base-material of the liquid epoxies colored paint the most of low molecule amount, with modified fat
Fat amine or aliphatic cyclic amine as curing agent, have nontoxic, good leveling property, easy construction, environmental protection, one-pass film-forming thickness up to 1 ㎜ with
On, paint film smooth, wear-resisting, resistance to the advantages that typically chemicals corrodes.But solvent-free epoxy self-leveling coating is in construction, ground
Face and environment temperature typically require more than 15 DEG C that winter season can not solidify or solidification effect is poor, usual epoxy self-leveling
Occur in low-temperature setting and the film defect such as be unable to levelling, pasta, turn white, it is big additionally, due to epoxy resin fragility itself,
Limiting epoxy self-leveling coating is needing the application of the occasions such as impact resistance, rolling resistance.
Solvent polyurethane self-leveling floor coating is aiming at foregoing solvent type epoxy-polyurethane coating and solvent-free
The shortcomings that epoxy-polyurethane coating of type and the floor coatings of a kind of novel high-performance developed.It has good leveling property,
Thick can apply, can winter low temperature solidification, paint film be flexible, wear-resistant, impact resistance, good chemical resistance the advantages of, its low temperature
Curing performance, pliability, resistance to organic acidity can be better than solvent-free epoxy self-leveling coating.
Solvent-free polyurethane gravity flow self-leveling floor coating is different with polyurethane plastic plane materiel material, though polyurethane plastic rubber paving material
So and solvent-free Self-leveling and for higher elasticity, but it is to be suitable for plastic cement race track due to intensity and lower hardness
And synthetic court, be not suitable for industry ground slab.
It is an object of the invention to provide a kind of floor coatings of novel high-performance for the content of the invention.It has good leveling property, can
Thickness applies, can winter low temperature solidification, paint film is flexible, wear-resistant, impact resistance, good chemical resistance the advantages of, its low-temperature solid
Change performance, pliability, resistance to organic acidity can be better than solvent-free epoxy self-leveling coating.A kind of solvent-free, Self-leveling polyurethane
