Abstract

PURPOSE:To increase sliding resistance, prevent blinding, and variously change the water permeability performance by connecting a fiber-shaped aggregate and porous powder with thermo-setting resin. CONSTITUTION:A fiber-shaped aggregate and thermo-setting resin in the liquid state at the ordinary temperature are mixed in advance, porous powder is added and mixed, and the mixture is molded by pressure molding to manufacture a floor material. The water permeability quantity and water permeability coefficient are variously changed by changing the combination ratio between the fiber-shaped aggregate and the thermo-setting resin and the mixing ratio between the mixture and the porous powder.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flooring material, and particularly to a flooring material that is resistant to slipping even when used in wet conditions.

[Prior Art] Floor materials used in places that frequently get wet, such as bathrooms, galleys, toilets, and entrances, are required to be particularly resistant to slipping when wet.

Conventionally, the following techniques are known regarding this type of floor material.

By connecting and solidifying the surface of aggregates such as sand with a particle size of 0.3 mm or more with thermosetting resin, a water-permeable resin concrete layer with continuous water-permeable pores formed between the aggregates is formed, and these water-permeable pores are This allows water to permeate from the surface of the floor material to the back side, thereby preventing slipping when wet (for example, see Japanese Utility Model Publication No. 15308/1983).
.

■ By scattering particles on the surface of a floor material made of vinyl chloride resin, it imparts anti-slip properties to the surface of the floor material (for example, U.S. Pat. No. 4,196,243 and U.S. Pat. No. 4,239 , No. 797 specification at ++q
>.

■By forming irregularities on the surface of the flooring material, making the surface rough, and providing an elastic body on the surface, the flooring material can be improved.
Adding anti-slip properties to the surface of the material (for example, U.S. Patent No. 4.3
No. 36,293 and U.S. Patent No. 4.403,00
(See Specification No. 9).

[Problem to be solved by the invention]

However, in the configuration (2) above, since the diameter of the water permeable hole is large, foreign matter enters the water permeable hole along with water, causing clogging and reducing water permeability. In the configurations of ■ and ■ above, slipping is prevented by providing roughness to the surface of the floor material, such as by providing unevenness on the surface.
There are problems in that it gets dirty easily and has poor surface smoothness.

The present invention was made in view of the problems of the prior art described above, and it is an object of the present invention to provide a floor material that has good water permeability and is resistant to slipping even under usage conditions where the floor material frequently gets wet. Another object of the present invention is to provide a flooring material with excellent surface smoothness.

(Means for Solving the Problems) A floor material characterized in that it has porosity and is made by bonding fibrous aggregate and porous powder with a thermosetting resin that is in a liquid state at room temperature.

Further, this floor material is manufactured by pre-mixing fibrous aggregate and thermosetting resin, then adding and mixing porous powder, and then molding the mixture by pressure molding.

Examples of the fibrous aggregate used in the present invention include glass fibers such as fiber strands and milled fibers, mineral fibers such as asbestos, inorganic fibers such as whiskers and carbon fibers, and synthetic resin fibers such as nylon fibers and vinylon fibers. There is.

Porous used in the present invention? As the T powder, zeolite, hentonite, sepiolite, pumice, etc. are used.

The thermosetting resin that is in a liquid state at room temperature and used in the present invention includes unsaturated polyester resins, epoxy resins, polyurethane resins, etc. that can be used in a liquid state at room temperature.

The fibrous aggregate and the thermosetting resin are mixed in advance, and then the porous V powder is mixed with 200 to 800 parts by weight of the mixture of the fibrous aggregate and the porous powder to 100 parts by weight of the thermosetting resin. (
The ratio of fibrous aggregate to porous powder is 2=8 to 8:2
), and then mold by pressure molding.

[Effect]

Since the fibrous aggregate and the thermosetting resin are mixed in advance, the porous powder does not absorb the thermosetting resin and the pores become clogged, resulting in a porous powder with excellent water permeability. Furthermore, since the mixture of fibrous aggregate, thermosetting resin, and porous powder is molded by pressure molding, the surface becomes smooth.

Furthermore, since the water permeation holes are made of porous powder, fine contaminants such as impurities do not penetrate into the inside of the holes.

〔Example〕

The present invention will be explained below using examples.

Part 11 100 parts by weight of unsaturated polyester resin was mixed with 350 parts by weight of glass chopped strands, and 50 parts by weight of zeolite (volume ratio of glass chopped strands and zeolite was 8:2) was added to this mixture and mixed. After that, it is filled into a mold and press-molded at room temperature. The molded product was heated and cured in an oven to obtain a floor material.

This floor material has porous powder uniformly dispersed in a mixed phase of fibrous aggregate and thermosetting resin, and is strongly bonded.

For comparison with the floor material according to the present invention, Example 1
The composition was different from the previous one, and only glass chopped strands were used instead of glass chopped strands and zeolite, and a floor material was obtained by processing.

Resin concrete was produced by the method described in Japanese Utility Model Publication No. 57-15308.

Next, the surface smoothness, water permeability, and clogging property of the floor material obtained as described above were measured, and the results are shown in Table 1.

The surface smoothness was measured using the center line average roughness (Ra) shown in JIS B 0601.
) is less than 10μ rings, it is indicated by ◯, and when it is more than 10μ, it is indicated by ×.

Water permeability is measured based on JIS A 5403, and if the water permeability exceeds 1.0 cc/cm", -hr, clogging may occur, and if the water permeability exceeds 0.0 cc/cm", -hr.
04 cc/C1・hr If it is not grooved, it will slip when wet, so the water permeability will be 0.004~
1.0 cc/cm”-hrO is indicated by O;
0 cc/cm”・hr or more is indicated by △, 0.0
Those less than 04cc/ca"・h" are marked with an x.

The clogging property was measured by dispersing talc powder (particle size of 10 μm or more) in water at a rate of 0.2 g/cc, and adding this dispersion to +
00mm x 100+lll water permeable floor material 5
0cc is applied, and the talc powder remains on the surface of the flooring material, and it is determined whether it can be washed off later. If it is possible to wash it off later, it is indicated by ○. Cases where clogging occurs are indicated with an x.

For the measurement of slip resistance, an artificial leather test piece was used instead of felt in JIS A 5721, and an artificial leather test piece (50 mm x 30 + am, load 3k
g), and a friction coefficient of 0.8 or more is indicated by a circle, and a coefficient of friction of 0.8 or more is indicated by a circle.
6 to 0.8 was indicated by △, and less than 0.6 was indicated by ×.

As can be seen from Table 1, the surface smoothness, water permeability, clogging resistance, and slip resistance of the flooring material according to the present invention were all rated as ○, whereas all comparative examples were rated as ×. There is something like that.

Table 1 [Effects of the Invention] As described above, the floor material of the present invention has good water permeability, has a smooth surface, has slip resistance, and is free from clogging.

In addition, by changing the blending ratio of fibrous aggregate and thermosetting resin, which serve as reinforcing fillers, and the mixing ratio of these mixtures and porous powder, we can create various water permeability properties with different water permeability and water permeability. flooring materials can be obtained.
