Definitions

  • the present invention relates to a residential environment improving material comprising microcapsules each containing porous fine particles as a major component, and to a building material, laying material and spraying preparation using the same.
  • underfloor places are places collecting or accumulating moisture and hence permit easy proliferation of vermin such as mites as well as termites and of miscellaneous germs such as mold. It is pointed out that there also arises a problem that such vermin and germs cause a building itself to decay or do damage to the health of residents of the building.
  • VOC volatile organic chemicals
  • the present invention has been made focusing on a porous particulate matter as a carrier of hinokitiol.
  • the present invention provides a residential environment improving material characterized by comprising a porous particulate matter as a major component, and a hinokitiol-containing liquid retained in pores of the porous particulate matter.
  • the porous particulate matter has the property of adsorbing various substances in their pores.
  • attention focused on the action of the porous particulate matter as a carrier by allowing the porous particulate matter to retain the hinokitiol-containing liquid in their pores, hinokitiol adsorbed by the porous particulate matter gradually volatilizes from the pores to exhibit various effects of improving residential environments such as a termite repellent effect, antimicrobial effect, vermin-proofing effect, VOC-eliminating effect, and relaxation effect over a long term.
  • porous particulate matter may be either an inorganic substance or an organic substance.
  • porous substances include diatomaceous earth, artificial ceramic particles, zeolite, hydroxyapatite, and composite particles comprising any one of those substances and an organic polymeric substance. Any one of these substances is suitable for use.
  • the porous particulate matter may be composed of either a single such substance or a mixture of two or more of the aforementioned substances.
  • diatomaceous earth has a moisture-conditioning property and hence has been attracting attention as a “breathing material”.
  • Diatomaceous earth which results from deposition of fossilized phytoplankton (diatom) in the bottom of sea or lake, comprises silicic acid as a major component, has a particle size of about 50 micrometers and is ultraporous with a multiplicity of micropores of about 0.1- to 0.2-micrometer diameter all over the surface and inside thereof.
  • diatomaceous earth has begun to be utilized as a useful building material having various properties and functions of diatomaceous earth such as incombustibility, heat-insulating property, condensation-preventive function, moisture-conditioning function, breathability, deodorizing function, waterproofing function and air-cleaning function. That is, by the use of diatomaceous earth as a carrier of the hinokitiol-containing liquid, it is possible to provide an excellent residential environment improving material having, in combination, the useful characteristics of diatomaceous earth and various characteristics of hinokitiol adsorbed and retained in pores of diatomaceous earth such as an antimicrobial property, vermin-proofing property, VOC-eliminating property, and relaxation effect.
  • artificial ceramic particles, zeolite and hydroxyapatite have various useful properties and functions such as incombustibility, heat-insulating property, condensation-preventive function, moisture-conditioning function, breathability, deodorizing function, waterproofing function and air-cleaning function and hence are capable of forming excellent residential environment improving materials.
  • a liquid preparation extracted from a wood such as Aomori hiba (Thujopsis dolabrata Sieb. et Zucc.) or Taiwan hinoki (Chamaecyparis obtusa Endl. var. formosana Rehd.), or a solution of chemically synthesized hinokitiol can be used as the “hinokitiol” used herein.
  • the porous particulate matter may be allowed to retain hiba oil (oil extracted from Thujopsis dolabrata Sieb. et Zucc.).
  • hiba oil oil extracted from Thujopsis dolabrata Sieb. et Zucc.
  • the aforementioned effects of hinokitiol such as antimicrobial effect, vermin-proofing effect, VOC-eliminating effect, and relaxation effect can be obtained since hiba oil contains hinokitiol in abundance, while at the same time the cost and time required for the preparation of the residential environment improving material can be reduced since the process of extracting hinokitiol from hiba oil can be eliminated.
  • hiba oil which is a natural substance, in the residential environment improving material, the residents in a house (or workers in an office or the like) constructed using the residential environment improving material can rest assured.
  • Examples of building materials using such a residential environment improving material include: a building foundation comprising a concrete composition as a chief material and the residential environment improving material incorporated therein; a moisture-proof sheet comprising a water-impermeable sheet body as a chief material and the residential environment improving material incorporated therein; a building wall formed from a material comprising the residential environment improving material as a chief material; a plate-shaped wall panel to be affixed to a building wall, the wall panel comprising plaster or the like as a chief material and the residential environment improving material incorporated therein; a foamable building material for use as applied onto a wall, floor, ceiling or an analog in a building, the foamable building material comprising a foamable building material body and the residential environment improving material retained by or incorporated in the foamable building material body; and a tatami mat comprising at least a tatami body and a tatami cover as chief materials and the residential environment improving material incorporated in the tatami body.
  • a laying material which uses the residential environment improving material of the present invention is a laying material to be laid in an underfloor space of a building or its periphery, and an example of such a laying material comprises a container which is permeable to air outwardly and inwardly thereof and the residential environment improving material contained therein.
  • An example of a spraying preparation using the residential environment improving material comprises a composition containing the residential environment improving material and is capable of being sprayed to or mixed with a foundation part of a building, soil around the foundation part, and a floor, wall and an analog in the building.
  • the residential environment improving material is preferably used in combination with wood powder containing hinokitiol. While the proportion of the residential environment improving material is desirably about 3% in a building material or about 1% to about 20% in a spraying preparation, there is no particular limitation thereto and it is possible for such a material to contain the residential environment improving material in an appropriate proportion more than or less than the aforementioned value or range, taking cost-effectiveness into consideration.

  • FIG. 1 is a schematic sectional view showing a residential environment improving material 1 according to this embodiment.
  • the residential environment improving material 1 includes a porous particulate matter comprising artificial ceramic particles 11 composed mainly of a high-purity ceramic, and hiba oil 12 contained in pores 11 a of the porous particulate matter.
  • the artificial ceramic particles 11 are each an ultraporous particle having an average particle diameter of about 7 micrometers with the pores 11 a consisting of innumerable micropores.
  • Hiba oil 12 is an oil-soluble component of a liquid obtained by applying high-temperature and high-pressure steam to finely pulverized wood chips, bark, branches and leaves, or the like of Aomori hiba (Thujopsis dolabrata Sieb. et Zucc.) or Taiwan hinoki (Chamaecyparis obtusa Endl. var. formosana Rehd.), the oil-soluble component containing hinokitiol in abundance.
  • a mixed liquid is previously prepared by diluting a hinokitiol-containing liquid with alcohol; artificial ceramic particles 11 are introduced into this mixed liquid to allow the pores 11 a thereof to adsorb the mixed liquid; thereafter, excess mixed solvent is removed by filtration; and then the alcohol content is removed away from the mixed liquid adsorbed by the pores 11 a by natural drying or warm-air drying to give the residential environment improving material 1 in a dried condition.
  • artificial ceramic particles 11 are allowed to adsorb the mixed liquid prepared by diluting the hinokitiol-containing liquid with alcohol.
  • the hinokitiol-containing liquid comprising hiba oil 12 has a very high viscosity, which is inconvenient for handling in allowing artificial ceramic particles 11 to adsorb the liquid as it is, and exhibits low adsorption efficiency. For this reason the viscosity of the whole mixed liquid is lowered by dilution to eliminate such an inconvenience. Since alcohol becomes an unnecessary component in the final stage, alcohol is removed at the final procedural step. While various alcohols are applicable in the present invention, use of edible ethanol having a low impurity content is particularly desirable.
  • FIGS. 3 and 4 the termite-proofing test on the residential environment improving material 1 and the results thereof are explained.
  • the test is in compliance with “Ant-proofing Effectiveness Test Method for Ant-proofing Agent adapted for Soil Treatment and Indoor Test Method based on Performance Standard (1)”, Japan Wood Preserving Association standard No. 13 (1992). Brief description of the test method follows.
  • FIG. 2 As shown in FIG. 2 [sic], two branched glass test tubes TT 1 and TT 2 are positioned with their respective branch portions facing each other and a glass tube GT having opposite open ends is inserted into the branches.
  • the glass tube GT contains therein a test sample X and is calibrated with graduation lines 0 to 5 equally spaced by about 1 cm longitudinally from one side (from the right-hand side in the figure).
  • One test tube TT 1 (the right test tube in the figure) contains therein untreated soil Y and a predetermined number of termites (not shown), while the other test tube TT 2 (the left test tube in the figure) contains therein chips Z of a Japanese red pine as an aliment for the termites.
  • the upper ends of respective tube tubes are covered with perforated aluminum foils TTa. That is, this test is to examine to which graduation line the termites advance in the test sample X from the test tube TT 1 at a predetermined temperature in a predetermined time period to eat the Japanese red pine chips Z.
  • FIG. 3( a ) [sic] shows the contents of each test condition for the test sample X.
  • the term “calcium borate-containing power”, as used hereinafter, is sand produced by pulverizing an ore containing calcium borate.
  • test condition A where the proportion of the residential environment improving material 1 in the test sample X was 100%
  • test condition B where the test sample X comprised 40% of the residential environment improving material 1 and 60% of calcium borate-containing powder
  • test condition C where the test sample X comprised 20% of the residential environment improving material 1 and 80% of calcium borate-containing powder
  • test condition D where the proportion of calcium borate-containing powder in the test sample X was 100%
  • test condition E where the test sample X comprised 20% of the residential environment improving material 1 and 80% of sandy loam
  • test condition F where the proportion of sandy loam in the test sample X was 100%.
  • the test condition G was a condition where the residential environment improving material 1 was put only between graduation lines 3 and 4 and sandy loam was put between graduation lines 0 and 3 and between graduation lines 4 and 5 .
  • FIG. 4( b ) The test results are shown in FIG. 4( b ). Each value in FIG. 4( b ) represents a piercing degree. A lower value indicates a higher termite-proofing effect. As can be seen from FIG. 4( b ), a very high termite-proofing effect was obtained under the test condition A where the proportion of the residential environment improving material 1 in the test sample X was 100%. A high termite-proofing effect was obtained under each of the test conditions B, C and E where the test sample X comprised 40% or 20% of the residential environment improving material 1 , regardless of whether calcium borate-containing power or sandy loam with which the residential environment improving material 1 was mixed.
  • the combination of the residential environment improving material 1 with calcium borate-containing powder exhibited a higher termite-proofing effect than did the combination with sandy loam. It can be said that a low or substantially no termite-proofing effect was obtained under each of the test conditions D and F where calcium borate-containing power or sandy loam was used alone as the test sample X. From the test result that the termite-proofing effect was low under the test condition G, it can be understood that uniform mixing of the residential environment improving material 1 with sandy loam (test condition E) provided for a higher termite-proofing effect than did the case of the residential environment improving material 1 disposed in a localized fashion relative to sandy loam.
  • the residential environment improving material 1 is applied to a spraying preparation 10 to be sprayed onto a foundation part B (concrete foundation) of a building constructed on a cobble stone layer laid in soil S with an intervening moisture-proof sheet WRS and onto the soil S around the foundation part B.
  • the spraying preparation 10 is a liquid preparation prepared by mixing the residential environment improving material 1 and wood chips 2 such as of Aomori hiba with water serving as a base material and adapted to be sprayed by means of a sprayer P.
  • Wood chips 2 are produced by pulverizing bark, branches and leaves or the like of Aomori hiba or a like wood containing hinokitiol in abundance (such as Taiwan hinoki or the like) to a size of about several millimeters. Since each particle of the residential environment improving material 1 and each wood chip 2 are very fine, they are shown exaggeratedly in FIG. 6. In this application the residential environment improving material 1 and wood chips 2 are each blended in a proportion of about 3% based on the overall weight of the spraying preparation 10 . Note that this proportion is not limited to 3% and may be varied appropriately. Since the residential environment improving material 1 and wood chips 2 are solid, they are particularly easy to store and transport and can be mixed with water to prepare the spraying preparation 10 at a spraying site for immediate use. For this reason, the spraying preparation 10 is advantageous in handling property.
  • a termite control agent 100 is poured to a level substantially equal to the upper level of the cobble stone layer A and then pressure is applied from above to form a layer of the termite control agent 100 . Thereafter, concrete is poured onto the moisture-proof sheet WRS covering the termite control layer 100 to form the concrete foundation part B. In this way the termite control agent 100 can be included in the soil S in a predetermined region by a very easy operation.
  • the termite control agent 100 is one prepared by mixing 2 parts by weight of the residential environment improving material 1 and 8 parts by weight of sandy loam powder, taking the aforementioned test results into consideration. This ratio meets the aforementioned test condition that provided for a very high termite repellent effect. It should be noted that a layer of the termite control agent 100 having a thickness of about 1 cm may be provided under or over the cobble stone layer A.
  • An alternative satisfactory termite-proofing measure can be provided by mixing the residential environment improving material 1 , sandy loam and concrete powder with water at predetermined ratios and pouring the mixture onto the cobble stone layer A thinly to form a base for the foundation part B, instead of using the termite control agent 100 .
  • hinokitiol since wood chips 3 release hinokitiol little by little and continues releasing hinokitiol even after the releasing of hiba oil 12 from the residential environment improving material 1 has been almost completed and the effect of hiba oil 12 has become faint, the termite repellent effect and like effects continue over a longer term.
  • the effects of hinokitiol thus released include not only the termite-proofing effect but also a vermin-proofing effect against vermin such as mites, a microorganism sterilizing effect and an antimicrobial effect against mold, bacteria and the like, and the effect of eliminating VOCs causing sick house syndrome such as formaldehyde released from synthetic resin adhesives, new building materials and the like used in a building.
  • an extracted liquid (a water-soluble or oil-soluble component for example) extracted from Aomori hiba or the like as a base material of the spraying preparation in addition to water enables the aforementioned effects to be enhanced. It is also possible to mix only the residential environment improving material 1 with the base material of the spraying preparation 10 .
  • a second application of residential environment improving material 1 shown in FIGS. 7 to 9 is an application where the residential environment improving material 1 is applied to a laying material 20 to be laid or buried in an underfloor space Fs of a building or the soil S around the underfloor space Fs.
  • the number of laying materials 20 to be laid in the underfloor space Fs or around the foundation part B, spacing between adjacent laying materials 20 thus laid, the depth to which the laying materials 20 are to be buried and the like can be appropriately determined depending on the extent of a building to be constructed, budgetary limits and other factors. If possible, laying materials 20 may be laid in the underfloor space Fs or the soil S even after the completion of the building. As schematically shown in FIG.
  • each laying material 20 comprises a bag-like container 21 , and residential environment improving material 1 and wood chips 2 contained in the container 21 .
  • the container 21 comprises, for example, an air-permeable material such as a hempen bag or a nonwoven fabric bag. It is possible to use various other types of bags or pouches such as a bag to be used usually as a sandbag or the like.
  • the residential environment improving material 1 and wood chips 2 used in this application are the same as used in the foregoing first application.
  • the container 21 may contain earth, sawdust or the like additionally. It is possible that the container 21 contains only the residential environment improving material 1 .
  • Such laying materials 20 are laid in the underfloor space Fs defined by the foundation part B and the floor F of the building and the soil S or buried in the soil S outside the building and around the foundation part B.
  • the action of hinokitiol contained in hiba oil 12 released from the residential environment improving material 1 exerts a termite-proofing effect, fungiproofing effect and like effects for a short term as well as for a medium or long term.
  • Hinokitiol released from wood chips 2 exhibits its effects for a longer term, as in the first application.
  • FIGS. 10 and 11 A third application of residential environment improving material 1 showing in FIGS. 10 and 11 is an application where the residential environment improving material 1 is applied to a foamable building material 30 comprising rock wool 31 used as its building material body.
  • FIG. 10 is a partially cutaway view of a wall of a building sprayed with the foamable building material 30 .

  • the tatami body 2 comprises a core material 511 formed of a rigid foamed synthetic resin material such as polyurethane foam, polystyrene foam and polyethylene foam, and a pair of board materials 512 positioned on the obverse and reverse sides of the core material 511 , the board materials 512 each comprising a so-called particle board formed from small pieces of wood (sawdust, splinters or the like) by compression forming.
  • a multiplicity of residential environment improving materials 1 as used in each of the foregoing applications are included in the synthetic resin material used as the chief material of the core material 511 .
  • wood chips 2 are included in the board materials 512 .
  • the proportion of such residential environment improving materials 1 relative to the synthetic resin material and the proportion of wood chips 2 relative to the board material 512 are each about 3% by weight. This value is not necessarily limited.
  • the core material 511 may incorporate the residential environment improving materials 1 either alone or in combination with wood chips 2 . Though not shown, it is possible that residential environment improving materials 1 , wood chips 2 or the like are made to adhere to or incorporated in the tatami covers 52 or the sheet materials 53 .
  • tatami mat 50 With such a tatami mat 50 , it is possible to prevent sick house syndrome caused by VOCs released from new building materials, synthetic resin adhesives or the like over a long term from the initial stage of construction by virtue of the VOC-eliminating action of hinokitiol contained in hiba oil 12 continuously released from the residential environment improving materials 1 and wood chips 2 incorporated in the materials of the tatami body 51 . Further, it is possible to inhibit proliferation of mites, termites and miscellaneous germs such as mold in the tatami mat 50 itself, walls, floor and rooms.
  • the tatami mat 50 can also exhibit high moisture-conditioning performance by virtue of the moisture-conditioning action of artificial ceramic particles 11 forming the residential environment improving material 1 and that of wood chips 2 . Additionally, the residents can also enjoy the relaxation effect of hinokitiol released indoors from the tatami mat 50 .
  • the porous particulate matter functioning as the carrier of the liquid containing hinokitiol such as hiba oil 12 in the residential environment improving material 1 of the present invention may comprise, as a major component thereof, zeolite (not shown), hydroxyapatite (not shown), or composite particles 60 (silica-coated polyethylene particles for example) comprising artificial ceramic particles 61 having an average particle diameter of about 10 micrometers to tens of micrometers and an organic polymeric substance 62 (polyethylene for example).
  • Zeolite is an ore of silicic acid salt hydrate comprising silica (about 70%) and alumina (about 10%) as major components, and an alkali metal oxide, an alkali earth metal oxide, an iron oxide and the like and having pores consisting of innumerable micropores.
  • Zeolite has an average particle diameter of about 0.2 to about 0.6 mm and a surface area larger than artificial ceramic particles 11 and hence is capable of adsorbing an increased amount of hiba oil 12 in its pores per particle.
  • zeolite As a result, by simply mixing zeolite with hiba oil 12 as used in the foregoing embodiment at ratio of 10:1, the pores of zeolite can absorb hiba oil 12 containing hinotitiol in an amount sufficient to exercise the termite-proofing, vermin-proofing and antimicrobial functions and like functions.
  • There are two types of zeolite one being synthetic zeolite prepared by artificial synthesis, the other being natural zeolite which is powder prepared by crushing a natural zeolite ore. Particularly where natural zeolite is used in the residential environment improving material 1 , the user can utilize the residential environment improving material 1 with ease since natural zeolite is inexpensively available.
  • Composite particles 60 each have a structure wherein artificial ceramic particle 61 is embraced with the organic polymeric substance 62 . Since the organic polymeric substance 62 expands with rising temperature or contracts with lowering temperature, composite particles 60 have a feature that their pores 61 a are closed or exposed correspondingly thereto. As a result, hiba oil 12 containing hinokitiol is retained by or released from composite particles 60 over a medium or long term, thereby exhibiting the termite-proofing effect of hinokitiol efficiently. It is possible to use a mixture of two or more types of these porous particulate matters appropriately. A method of preparing a residential environment improving material employing such a porous particulate matter as the carrier is similar to the method of preparing the residential environment improving material 1 employing artificial ceramic particles according to the subject embodiment.
