CONSTITUTION:An inorganic bulk material 200-1200 pts.wt. is combined and connected to unsaturated ester resin 100 pts.wt. added with a basic compound, and the mixture is molded by pressure molding to manufacture a floor plate. NH2C2H4OH and NH(C2H4OH)2 are preferable for the basic compound, and an aggregate is preferably added to talc, kaolin, silica sand for the inorganic bulk material. Pressure molding is performed by press molding or calendar molding.

Description

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

[Conventional technology]

Flooring materials used in places that frequently get wet, such as bathrooms, kitchens, 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 or more with thermosetting resin, a water-permeable resin concrete layer with continuous water-permeable pores formed between the aggregates is formed. These water permeable holes allow water to permeate from the surface of the floor material to the back side, 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. Patent Section 4,196°243 and U.S. Patent Section 4 .239,797).

■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 material surface (e.g., U.S. Patent Section 4.3)
No. 36,293 and U.S. Patent Section 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 has been made in view of the above-mentioned problems of the prior art, and provides a floor material that is resistant to clogging and maintains slip-resistant performance over a long period of time even under usage conditions where wet conditions occur frequently. 6.
Another object of the present invention is to provide a floor material whose surface is resistant to staining and has excellent surface smoothness.

[Means to solve the problem]

The floor material of the present invention consists of 100 parts by weight of unsaturated polyester resin added with a basic compound and 200 to 1 part by weight of inorganic powder.
It is manufactured by blending and bonding 200 parts by weight and molding by pressure molding.

Basic compounds added to the unsaturated polyester resin used in the present invention include Na0Il, KOII, Ca

Inorganic powders used in the present invention include aggregates such as talc, kaolin, clay, silica sand, and mica, powders of inorganic fibers such as glass fibers, ashest fibers, and carbon fibers, ceramic powders, glass powders, and metal powders. can be given. In particular, aggregate inorganic fiber powder is more preferably used.

Pressure molding is performed by press molding, calendar molding, or the like.

[Effect]

The floor material of the present invention is prepared by adding 0.5 to 10% of a basic compound to an unsaturated polyester resin, stirring and mixing the mixture, and then adding an initiator. Next, inorganic powder is blended in an amount of 2 to 12 times the weight of the resin, mixed and bonded by high-speed stirring, and the mixture is molded by pressure molding such as press molding or calendar molding.

By adding a basic compound to the unsaturated polyester resin, the carboxylic acid at the end of the unsaturated polyester resin becomes a salt, which improves the adhesion between the unsaturated polyester resin and the inorganic powder, and the flooring material becomes smooth,
It is less likely to get dirty and has improved durability, and because it contains a large amount of inorganic powder, it has porosity, good water permeability, good durability, and does not slip easily when wet.

〔Example〕

Hereinafter, the present invention will be explained with reference to examples. To 100 parts by weight of Yufuniba Masudo unsaturated polyester resin (acid value 28), one part by weight of monoethanolamine is added, and to this, 800 parts by weight of silica sand powder (200 mesh pass) is added. After stirring at high speed to mix, the mixture was press-molded (50 kg/ct) at room temperature, and then heated and cured at 80°C to produce a floor material with a diameter of 30 (Jim x 5M in thickness).

Example I 1 part by weight of jetanolamine was added to 100 parts by weight of an unsaturated polyester resin (acid value 31), 450 parts by weight of wollastonite (5Q Mesh bath) was added thereto, and the resin was treated in the same machine as in Example 1. The floor material was produced using the same method.

A floor material was produced in the same manner as in Example 1 except that monoethanolamine (basic compound) was not added.

Comparison I A floor material was produced in the same manner as in Example 2 except that jetanolamine (basic compound) was not added.

A floor material was produced in the same manner as in Example 1, except that 1,300 parts by weight of silica sand (200 Mesh bath) was added.

1 part by weight of monoethanolamine was added to 100 parts by weight of unsaturated polyester resin (acid value 2 s), 51,150 parts by weight of talc was added thereto, and the same treatment as in Example 1 was carried out to form a floor material. generated.

Next, the floor material produced as described above was evaluated for slip resistance by a sensory test when wet with water and measured for bending strength, and the results are shown in Table 1.

To evaluate the slip resistance when wet, a sample of the flooring material was placed horizontally, and the slippage was measured when the flooring material was dry and when it was wet with tap water constantly flowing over the surface of the flooring material. A sensory test was conducted with a person (about 60 kg in weight) riding on rubber-soled shoes, and items that were easy to slip were marked with an x, and items that were difficult to slip were marked with an ○.

The bending strength was measured based on JIS K 7203.

Table 1 The bending strength of the floor material according to the present invention is 2.14 kg/
mm” or more and has excellent durability.

〔Effect of the invention〕

As described above, the floor material according to the present invention has good water permeability due to the porosity caused by the voids in the powder and granules, and is difficult to slip when wet. Furthermore, the adhesion between the unsaturated polyester resin and the inorganic $51 granules is improved (to improve wettability), thereby providing a floor material with excellent durability, a smooth surface, and stain resistance.

that's all
