Description
Technical field
The present invention relates to a kind of floor more particularly to a kind of modeling PU highly-elastic urethane floors.
Background technique
Floor refer to using certain material and technique to original ground carry out construction processing and show it is certain decorative and
Functional ground.It can be divided into: epoxy self-leveling floor, diamond dust abrasion-proof terrace, epoxy terrazzo terrace, cement base water mill
Stone, epoxy color sand terrace, epoxy antistatic floor, the anti-skidding terrace of epoxy, polyurea anti-corrosion terrace, polyurethane floor, silicon PU terrace,
Concrete dense curing agent terrace etc..This classification is from " purposes demand " specifically includes that 1, adapts to driveway, parking
HI high impact required for field, logistics warehouse etc., the requirement of high abrasion；2, such as engineering shop ground oil-seepage requirement；3, change
The requirement of work production chemicals-resistant dielectric corrosion；4, computer control room, Flour production dust, textile industry fiber dust, fuel oil,
Inflammable and explosive dangerous goods repository ground prevents the requirement of electrostatic accumulation；5, Electronic Components Manufacturing, operating room, food, medicine,
Precision machinery produces clean floor requirement of assembly area etc..
Movement is a most important ring, either indoor and outdoor basketball court, foot in the society for requiring crowd massing risk to grow up now
Court, court etc. require to do terrace, because the elasticity of terrace is necessary to movement.Existing athletic ground such as silicon
PU, plastic cement race track, surface layer is all relatively soft, is unable to load-bearing, when there is weight to be pressed in above, can cause repair to elastomer portion
Renaturation is destroyed.The construction on athletic ground is limited by place sometimes, other than undertaking motor function, also needs to undertake part road function
Can, allow the power-driven tools such as automobile to pass through above.Ordinary silicon PU, plastic cement race track surface layer be flexible material, when have automobile etc. weight
Object can cause to damage when above to surface material.
Summary of the invention
To solve the above problems, the modeling PU strong and wear-resisting the object of the present invention is to provide a kind of load-bearing capacity is high-elastic poly-
Urethane floor.
The technical scheme is that
A kind of modeling PU highly-elastic urethane floor is by bottom, elastic layer, enhancement layer, colored paint layer and super abrasive top coat layer group
At the bottom is laid immediately on ground, is stated elastic layer and is laid immediately on above bottom, the enhancement layer is laid on elastic layer
Top, the colored paint layer are laid on above enhancement layer, and the super abrasive top coat layer is laid on above colored paint layer.
The bottom is that no-solvent polyurethane is evenly applied to be formed by cement flooring or asphalt floor.
The elastic layer is the solvent-free moisture cure urethanes elastic layer of 6.5mm thickness, and extension elongation rate >=800% stretches strong
Degree >=1.0MPA.
The strengthening layer is the wet-solidifying single-component polyurethane strengthening layer of 2.5MM thickness, elongation percentage >=500%, stretch breaking strength
>=6.0MPA, hardness Shao A:80.
The super abrasive top coat layer is the no-solvent polyurethane super abrasive top coat layer of wearability 4H.
Construction and construction requirement:
(1), primary coat is handled
(1), with roller or flush coater by every square metre of 0.1-0.15kg(depending on primary coat viscosity) carry out solvent-free poly- ammonia
Ester primary coat processing, the area requirement whole roller coating of plastic cement paved surface or spraying in place, must not there is missed areas；
2) it is laid in first 1 hour and completes in plastic cement in primary coat treatment principle, elasticity is carried out before primary coat surface drying does not form a film
Layer is laid with, to ensure the adhesive strength of elastic grain bullet layer and basis；
3) when primary coat is handled to the facade at expansion joint also must roller coating in place；
(2), elastic layer is laid with
(1), the laying of STP monocomponent moisture cure no-solvent polyurethane elastomer only need to be added drier, pour into blender
It is interior, uniform stirring 2-3 minutes, until stirring evenly.
(2), the material stirred evenly is transported to paving site, a blade coating is on the basis of, thickness 6.5mm.
(3), the thickness (control is in 6.5mm) and flatness that timely follow-up investigations pave in work progress, to deficiency
The region 6.5mm will carry out and fill up, correct, and partly flat degree and thickness will ensure thickness when there is contradiction；
(3), strengthening layer is laid with
(1), the laying of monocomponent moisture cure no-solvent polyurethane strengthening layer, only needs uniform stirring；
(2), the material stirred evenly is transported to paving site, a blade coating is on the basis of, thickness 1.5mm；
(3), the thickness that timely follow-up investigations pave in work progress (control is in 1.5mm)；
(4), polyurethane colored paint layer
Colored paint layer is prepared in proportion, is constructed using roller, roller coating 2 times, it is desirable that without show-through, lustrous surface is uniform；
(5), it crosses
Colored paint layer is prepared in proportion to be crossed according to designed pattern graticule.
(6), no-solvent polyurethane super abrasive hyaline layer
Three component A:B:C are prepared as required；With roller roller coating 1 time, guarantee uniformly without show-through.
The beneficial effects of the present invention are: modeling PU highly-elastic urethane floor of the invention, suitable for commercial flexibly plane materiel
Material mainly solves cracking, wear-resisting, acid and alkali-resistance, weather resistance, produces when Gao Yundong, High Voltage, high abrasion to improve
The service life and the scope of application of product.800% elongation percentage, it is subsequent that intensity 1.0Mpa elastic polyurethane can effectively prevent basis cracking
It is not broken that floor is held in continuation of insurance；Tensile strength >=6.0MPA, shore hardness >=80A no-solvent polyurethane wearing layer, provides hardness,
So that terrace is provided effective bearing capacity, locomotive etc. is allowed to travel above；Wearability 4H, no-solvent polyurethane ultrawear-resistant material are
This product provides wear-resistant coat, improves service life.
The present invention is suitable for middle and primary schools, the basketball court of institution of higher learning, volleyball court, court；Movable square, health and fitness facilities
Area, boat paradise；The limit sports grounds such as skidding, slide plate, the bicycle of special wear-resisting requirement；Indoor elasticity jointless floor, such as
Hospital, exhibition room, waiting room etc. need the particular fields such as flat noise reduction, elasticity, wear-resisting, seamless sterile, antiacid alkali；Short term parking
Deng.
