ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates to treatment agent for surface-treating and/or cleaning and wooden building materials impregnated with the treatment agent, more particularly, to the treatment agent, made of natural materials, for surface-treating and/or cleaning articles and structures disposed in and/or assembled into houses and buildings, and to the building materials like floorboards treated with said treatment agent, which are useful and unstimulative to skin of human beings and exhibit natural pharmaceutical effects, protecting effects from molding and from infesting with insects, ability of waterproofing and cleaning.
PRIOR ART
Recently, even in community facilities like hotels and halls flooring made of wooden materials has been actively adopted. One of the reasons is that wooden floor is more comfortable to walk on than synthetic resin products, e.g., vinyl chloride panel, another is that the introduction of wooden products matches with current life of natural-oriented type. On the other hand, walking with shoes on is unavoidable in lobbies and on passageways of the facilities being highly public, therefore their floorboards are needed high durability and high wear proof. In result, natural materials like Japanese cypresses and elm trees not only have been introduced but often coated on their surfaces with materials having the function of increase of wear proof and water proof.
The surfaces of wooden floorboards, being used under the circumstances of walking with shoes on and/or of coming and going frequently, are coated in, e.g., at least three layers by urethane. However, they do not often result in withstanding long-term use because of decrease of natural air permeability based on covering the surfaces thereof with opaque films and because of stagnating humidity beneath the floorboards.
In consideration of that there are few customs of walking with shoes on in rooms in Japan or most of countries of Asia, and of that a wet climate often continues for a long period, multi-layers coating mentioned above is inappropriate in the case that wooden materials are applied to floors of rooms, passages in houses and floors of hotels and gymnasiums. Because the surface structure of floorboards coated in multi-layers does not result in matching with peculiar climates by means of hindering natural breathing, i.e., humid controllability of boards. Moreover, it will become undesirable that smooth and comfortable touch of floorboards without spoiling the originality of wood is given during walking barefooted or with slippers.
Recently, performances of heat insulation and air-tightness of houses have been quickly improved, therefore, chemical substances contained in building materials, etc., often tends to cause chemical substances allergy, e.g., a headache, nausea and dizziness and so on, sick house syndrome group and cutaneous inflammation of atopic diseases, etc. As a matter of course, the concern about such problems has been so deep that it should been solved soon. It has been desired that natural materials is actively adopted for floorboards used in houses and buildings aiming at natural-oriented life, and extremely to say, leaving original woody characteristic on the surfaces thereof.
Meanwhile, it is indispensable for the surfaces not to be stained even if coffee, wine or soy-source spills on them. Nowadays, coating with wax or oil of natural materials has been widely noticed. From this background, as treatment agent of natural materials for coating on floorboards, etc., coconut oil and linseed oil have begun to use.
Needless to say, the coconut oil mentioned above is extracted from coconuts, of course, being very fatty. It has a disadvantage decreasing the air permeability of wooden floorboard though being vegetable oil. In addition, its melting point is rather high so that a coating work is not always easy for home working.
On the other hand, linseed oil which exists in flax seeds, is well-known to be used as substitute materials for making paint, wax, linoleum, printing ink and rubber. Though this is a kind of oil, its oil ingredient is only 30% to 40% at most and its characteristic is similar to wax. When such linseed oil is coated on floorboard, thereafter the floorboard will be as if to be waxed, keeping the surface thereof dry, on the other hand, resulting in decrease of the effect for dispersing moisture existing in boards, i.e., in inhibition of the air permeability thereof. Moreover, it is said that wax is characteristic of absorbing dust in the atmosphere, the appearance of improved products and/or substitutes is ,therefore, desired.
Incidentally, since there are few suitable treatment agents for treating or washing surfaces of tatami mats made of knitted rush up to recently, the tatami mats are ordinarily cleaned by wiping only with cloth wetted by pure water, resulting in being clammy on the surfaces thereof for a short time thereafter. It is really expected to be possible to walk barefooted without feeling uncomfortable even just after treated and/or wiped. And it is also desired to prevent ticks from breeding and sundry bacteria from propagating in the mats so as to solve the most serious problems relating to daily life on tatami mats.
The first object of the present invention is to provide treatment agents for treating and/or cleaning the surfaces of wooden articles and structural members of houses and buildings, resulting in keeping original and comfortable touch of wood on the surfaces of articles, etc., also after being treated therewith, in being sanitary and hygienic and in exhibiting various natural pharmaceutical effects. The second object is providing wooden building materials impregnated with the treatment agents mainly comprising natural materials, resulting in matching with ecological- and natural-oriented life without spoiling natural appearance of wood, in ensuring air permeability for natural breathing of wooden building materials, and in being stable long and endurable against long-term use under peculiar humid climates.
THE PRESENT INVENTION
The present invention relates to treatment agent for surface-treating and/or cleaning for articles and structures disposed in and/or assembled into houses and buildings, the characteristic is that the agent contains cineole C

Eucalyptus oil mainly containing cineole may be also utilized for the treatment agent. Japan wax, beeswax, carnauba wax or emulsifier is applicable to the additives of the agent.
Wooden building materials like floorboards surface-treated by natural materials according to the present invention is impregnated and/or sprayed with the treatment agent containing cineole on the surfaces thereof.
According to the present invention characterizing in that treatment agent contains cineole, articles and structural members disposed in and/or assembled into houses and buildings may exhibit pharmaceutical effects based on cineole after the agent is impregnated thereon, resulting in being useful and unstimulative to the skin of human beings and in enabling surface-treating and washing sanitarily and hygienically.
Adopting eucalyptus oil mainly containing cineole actualizes the treatment agent made from complete natural materials. The agent including additives like Japan wax, beeswax, carnauba wax or emulsifier may display not only the pharmaceutical effects of cineole but glossing effect, water-repellentability, emulsifying effect and enhancing effect of cleaning power peculiar to each additive, resulting in increasing kinds of the function of agent.
Wooden building materials like floorboards impregnated with the treatment agent containing cineole may exhibit several natural pharmaceutical effects and may provide original and comfortable touch of wood and sanitary and hygienic circumstances appropriate to the walkers and residents. Moreover, the wooden building materials impregnated and sprayed with the treatment agent would not spoil natural breathing and humid controllability thereof, resulting in endurance of long-term use matching with peculiar humid clima
