Fig. 3 is the skeleton diagram of the measuring device of CSRB resistance coefficient, and Fig. 4 is the skeleton diagram of the measuring slide mass of CSRB resistance coefficient.4 wheels 21a, 21b can be free rotatably mounted on trolley 22.Slider 23 is installed below trolley 22, is loaded with counterweight 24a, 24b, 24c above, effect has normal load 785N (80kgf).The front of trolley 22 is equipped with draft arm 25, with horizontal plane at 18 ° of angles.
Breadboard 27 is horizontally installed on testing stand 26.
Trolley 22 is moved in parallel from testing stand 26 to be left a little, and the rubbing surface 23a of slider 23 is contacted and slided with the surface of breadboard 27.The contact area of slider 23 and breadboard 27 is 56cm2It and is certain.
Draft arm 25 is drawn by cam mechanism 28 with certain traction load speed 785N/S (80kgf/s), and dynamometer 29 is installed therebetween, and measurement acts on the tractive force of draft arm 25.
Traction peak load is calculated divided by the value of normal load and draws minimum load divided by the sum of the value of normal load, as CSR (resistance to sliding coefficient) B (bathroom).
The geomery of the rubbing surface 23a of slider 23 have it is various, in the present embodiment using simulation barefoot state pattern slider, as shown in Figure 4.
In the cross-section structure of slider 23, it is connected with the slider base portion 23b of trapezoidal cross-sectional shape on flat base portion 23c, is connected with thin plate 23d on the inclined surface of slider base portion 23b and upper bottom surface.The surface of thin plate 23d is rubbing surface.
In simulating the slider 23 under barefoot CSRB, thin slice 23d is the anti-skidding thin plate of rubber system, and it is 6.5mm in protrusion that using the material of Shore A hardness 75, the shape of convex portion, which is φ 7mm, and thickness is 4.5mm in flat.
In addition, carrying out barefoot practical walking test to breadboard, sliding property is evaluated.Fig. 5 is the chart for indicating the relationship of sliding evaluation criterion and coefficient of friction CSRB.It knows when CSRB is 0.8 or more, it is difficult to slide and safe.
In addition, being measured using surface roughness of the surfagauge to same breadboard.Also, to the concave-convex measurement arithmetic average gradient Δ a that arithmetic average roughness Ra is 0.4~5.0 μm and preferably 0.5~3.0 μm.The value of the Δ a of the bathroom floor of FRP is also as shown in table 1.
Fig. 6 is the chart of the relationship of the arithmetic average gradient Δ a of the coefficient of friction CSRB and tiny bumps when indicating barefoot.There are positive related between coefficient of friction CSRB and the arithmetic average gradient Δ a of tiny bumps when barefoot.By testing it is found that CSRB steeply rises when especially Δ a is more than 6.3.That is, discovery can improve skid resistance by the gradient for the tiny bumps being arranged on control bathroom floor.
Second embodiment
Various synthetic marble bathroom floors are made using casting.The production method of synthetic marble is the material resin that liquid is poured into the state of upper die and lower die closure, heats press molding and is manufactured.It is small to the frictional force of mould due to being the raw material of liquid.In addition, due to be liquid raw material, as long as clamping pressure very little.It therefore is the manufacturing process for being easy to maintain minute asperities.The concave-convex size that bathroom floor is equipped with is as shown in table 2.

Due to being formed with tiny bumps in embodiment material surface, when having water on floor surface, due to capillarity or the surface tension effects of water, effectively acted on to floor direction.That is, effectively acting on to the direction of absorption sole, result, which is felt, to be difficult to skid.
4th embodiment
It is coated on marking ink post legged to bathroom floor in sole, compares remaining marking ink trace on bathroom floor.
Relatively material biggish for the depth of upper flat face and lower flat face, the amount of remaining marking ink is seldom on floor, the absolutely not marking ink in slot.The depth of comparison material that is small for the depth of upper flat face and lower flat face but not forming minute asperities and upper flat face and lower flat face is small and is formed with the comparison material of minute asperities, it is identical as embodiment material, marking ink trace corresponding with sole shape can be confirmed on bathroom floor.
It is believed that the big comparison material of the depth of upper flat face and lower flat face due to few with the contact area of sole, is easy skidding.
The depth of upper flat face and lower flat face is small but does not form the comparison material of minute asperities, due to big with the contact area of sole, it can be considered that same as embodiment material in a dry state be not easy to skid.But, when floor surface has water, due to capillarity and the surface tension effects of water, embodiment material can obtain the effect that sole is adsorbed to floor, in contrast, the depth of upper flat face and lower flat face is small but does not form the comparison material of minute asperities and cannot obtain the effect, and therefore, the skid resistance soaked under state generates very big difference.In addition, small bumps can block the skin of sole, skid resistance is improved.
The depth of upper flat face and lower flat face is smaller than embodiment material but is formed with the comparison material of minute asperities, in the state of being soaked by water, since capillarity or the surface tension effects of water can obtain skid resistance, but, embodiment material, since the depth of upper flat face and lower flat face is appropriate, the edge effect that bumps difference generates can also be accessed, the state for being more difficult to skid is become.In addition, this skid resistance when dry also has difference.
The floor of the interface portion on floor, undress room and bathroom that bathroom floor of the invention can be used at the bathing in bathroom or the inside bottom of bathtub.
