Abstract

PURPOSE:To prevent a coefficient of friction from decreasing of a floor material, when it is wet with water, by containing a compounded material of spherical grain and granule in thermo-setting resin forming the floor material and a continuous space in the inside. CONSTITUTION:A floor material composite contains about 200 to 800pts.wt. material, compounding a spherical grain and a granule, for 100pts.wt. thermo-setting resin further kneads the material to be compounded in a range of weight ratio of the spherical grain to the granule about 0.05 to 0.5, and a floor material is formed by pressure molding this floor material composite. Thus formed floor material forms in its inside a continuous space, when the floor material wets its surface with water, it comes to infiltrate into the inside through a transmission water hole. Accordingly, a coefficient of friction of the floor material, when it is wet with water, can be prevented from large decreasing as compared with the coefficient of friction of the floor material when it is dried.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor-+1 which has excellent water permeability and is hard to slip when wet.

(Prior Art) Flooring materials used in areas where water is used, such as bathrooms, cooking rooms, toilets, and entrances, are required to have properties that prevent them from slipping when wet.

Conventionally, the following techniques have been proposed regarding such a water-permeable floor-shrine.

By connecting and solidifying the surface of aggregate such as sand with a particle size of 0.3 mm or more with a thermosetting resin, a water permeable resin concrete layer in which continuous water permeable pores are formed between the aggregates is formed.

The water-permeable holes formed in this water-permeable resin concrete layer allow water to permeate from the surface of the floor material to the back side, preventing slipping when wet.
(For example, see Utility Model Publication No. 57-15308).

■By scattering particles on the surface of a floor material made of vinyl chloride resin, non-slip properties are imparted to the surface of the floor material (for example, U.S. Pat. No. 4,196°243 and U.S. Pat. No. 4,239, 797).

■By forming irregularities on the surface of the floor material, making the surface rough, and providing an elastic body on the surface, the surface of the floor material is made non-slip (for example, U.S. Patent No. 4,333
6,293 and U.S. Pat. No. 4,403,009).

(Problem to be Solved by the Invention) However, in the above structure (■), since the diameter of the water permeable hole is large, foreign matter enters the water permeable hole together with water, causing clogging and reducing water permeability. There is.

In the configurations (1) and (2) above, since slipping is prevented by imparting roughness to the surface of the flooring material, such as providing irregularities on the surface, there are drawbacks that the flooring material is easily stained and has poor surface smoothness.

The present invention solves the above-mentioned drawbacks, and its purpose is to:
To provide a floor material that is resistant to slipping even under usage conditions where it frequently gets wet. Another object of the present invention is to provide a flooring material whose surface is resistant to staining and whose surface is excellent in smoothness.

(Means for Solving the Problems) The floor material of the present invention comprises a thermosetting resin, a granular material, and a spherical material having an average particle diameter of 0.5 to 5 times the average particle diameter of the granular material. 200 to 800 parts by weight of a blend of powder and spherical particles is contained per 100 parts by weight of the thermosetting resin,
And the weight ratio of the spherical particles to the powder is 0.05 to 0.
5 is contained, thereby achieving the above objective.

The present invention will be explained in detail below.

The floor material according to the present invention is a floor material composition containing a thermosetting resin, a granular material, and spherical particles having an average particle size of 1 to 5 times the average particle diameter of the granular material. Obtained by pressure molding.

As the thermosetting resin, for example, polyester resin, epoxy resin, phenol resin, furan resin, etc. are used.
In particular, polyester and epoxy resins are preferably used. Particles have a shape other than spherical, and include fillers used in resin concrete, lightweight aggregates for cement, and fiber reinforcing materials used in composite materials. Examples of the fiber reinforcing material include glass fiber, short alumina fiber, carbon fiber, and whiskers. In addition, as spherical particles,
Spherical particles such as glass beads, resin beads, metal shots, and hollow particles such as glass balloons can be used.

200 to 800 parts by weight of a combination of powder and spherical particles is contained with respect to 100 parts by weight of the thermosetting resin, and the weight ratio of the spherical particles to the powder is 0.
A floor material is obtained by blending and kneading the mixture in a range of 0.05 to 0.5 and press-molding this floor material composition.

200 parts by weight of the above compound per 100 parts by weight of the thermosetting resin.
By adding more than part by weight, continuous gaps (water permeable pores) will be formed inside the floor material to be formed, so that when the surface of the floor material gets wet with water, water will flow through the water permeable pores. Water on the surface will seep into the interior. Therefore, it is possible to prevent the coefficient of friction of the floor material when it is wet from being significantly reduced compared to the coefficient of friction when it is dry.

If the amount of this compound added is less than 200 parts by weight per 100 parts by weight of the thermosetting resin, a gap will be formed between the resin and the compound, making it difficult for the floor material to get wet. The coefficient of friction at is thicker (decreased) compared to when dry.The amount of the compound added is 800 parts by weight per 100 parts by weight of the thermosetting resin.
If the amount exceeds 1 part by weight, the kneading properties and moldability will be poor, and the strength of the resulting floor material will also be reduced.

The above-mentioned spherical particles are added in a weight ratio of 0.05 to 0.5 to the granular material. In particular, the amount of these spherical particles added is preferably 0.1 to 0.3 weight ratio to the powder or granular material.

By adding spherical particles in this way, the bearing effect improves the fluidity of the floor material composition when it is pressure-molded, resulting in a uniform composition and a smooth surface. Floor material is obtained.

Therefore, if the amount of spherical particles added is less than 0.05 or more than 0.5 in terms of weight ratio to the powder, the bearing effect due to the spherical particles cannot be expected and the moldability is poor. It turns out. The spherical particles used have an average particle size of 0.5 to 5.0 times the average particle size of the powder or granules. If the average particle diameter of the spherical particles is outside the above range, no bearing effect can be expected.

By blending a relatively large amount of the compound into the thermosetting resin, it is possible to form water-permeable pores that are formed in continuous pores, and the water present on the surface of the flooring material can be transferred to the water-permeable pores. It can flow downward through. Therefore, when wet, there is no large amount of water at the interface between the floor material and the object to be contacted, and the coefficient of friction when wet is not significantly reduced.

Moreover, when a large amount of powder or granules is blended into the resin in this way, the kneading properties and moldability of the floor material composition are greatly reduced. Since spherical particles are blended in a weight ratio, the bearing effect improves the fluidity of the floor material composition, allowing it to flow without any problem during pressure press molding.
This does not impair moldability and does not reduce surface smoothness.

Floor materials formed in this way, for example in bathrooms,
It is used as flooring material in kitchens, toilets, entrances, balconies, etc., or by laying it on poolsides, pavements, etc.

(Example) The present invention will be explained in detail below based on examples.

As shown in Table 1, 100 parts by weight of epoxy resin, alumina short fibers (average particle size 80 μm; value determined by biaxial average using optical microscopy), and glass beads (average particle size 16
200 parts by weight of a compound consisting of 200 parts by weight (glass pieces have an average particle size twice that of the alumina short fibers, and the glass beads have an average particle size twice that of the alumina short fibers; 0.05 weight ratio of fibers) was mixed, and then this floor material composition was filled between a press mold and a receiver mold, and the floor material composition was pressurized at room temperature. It was completely cured by heating at 80°C to obtain a floor material (30 mm x 30 mm).

Next, the slip resistance of the obtained floor material was measured, and the formability was visually observed.

Slip resistance was measured using an artificial leather test piece (50 mm x 30 mm, load 2 kg) when the floor material was wet with water, and a friction coefficient of 0.8 or more was determined as an O8 friction coefficient of 0.6.
A coefficient of friction of less than 0.8 is indicated by △, and a coefficient of friction of less than 0.6 is indicated by ×. For moldability, a uniform molded product was obtained with a ○, and a non-uniform molded product with a cross (poor fluidity and uneven pressure, resulting in non-uniform strength and appearance). . The results are shown in Table 1.

A floor material was obtained in the same manner as in Example 1, except that the formulation shown in Table 1 was used, and the slip resistance and formability of this floor material were evaluated in the same manner as in Example 1. The results are summarized in Table 1.

A floor material was obtained in the same manner as in Example 1 except that the formulation shown in Table 1 was used, and the slip resistance and formability of this floor material were evaluated in the same manner as in Example 1. . The results are shown in Table 1.

Tosuekuni - Using FRP bathroom floor material as a test specimen, Example 1
The slip resistance and moldability were evaluated in the same manner as in Example 1. The results are shown in Table 1.

(The following is a blank space) From the results in Table 1, it was confirmed that the floor material of the present invention was satisfactory in both slip resistance and formability.

(Effects of the Invention) As described above, according to the present invention, the water permeability of the floor material can be increased, and slipping when wet can be prevented. Moreover, even though a large amount of powder and granules are blended, since a predetermined amount of spherical particles are blended, the fluidity of the mixture is improved due to the bearing effect, and the moldability and surface smoothness are not impaired.

that's all
