Abstract

Sound and heat insulating material, light and solid, self-extinguishing without release of toxic fumes, obtained from monocots of the palmades family. Complementary treatments can give it better resistance to fire, insects and mold, make it water-repellent, waterproof or harden it

Description

-I- Unlike woody plants, well known, characterized by a part

  external generally tender and a little impregnable heartwood, the monocots, in particular the poaceae which have a hard and resistant woody stubble and the palmades whose stipe is made up of a large number of liberous bundles. have an internal part, often meristematic, where woody fibro-vascular elements are surrounded by

  poorly differentiated cells whose consistency is comparable to cork.

  It is difficult to find on the market a natural material which combines a very great lightness and a good mechanical resistance, which is sound and thermal insulator, which is

  self-extinguishing without emission of toxic fumes.

  Take for example the borassus flabelliformnis. The trimming of the stipe makes it possible to obtain very dark planks, of perfect wood in the peripheral part of the light brown planks of medium hardness suitable for making paneling in a middle part, finally planks of light beige color more tender and very light in the heart

of the stipe.

  The boards, whatever their section, from the heart of the stipe, have,

  naturally, excellent sound and thermal insulation characteristics and are self-

  extinguishable without release of toxic funmées. Their great lightness, and their natural structure allows new use in all areas where these properties are required, in particular to constitute insulation panels, for public places or

  private, ships, aircraft, but also, sandwich structures, for example, skis.

  In the raw state these boards are difficult to use because the xylem is impregnated with a sap with a high sucrose content which undergoes in a few hours, in the ambient environment, a significant microbial pollution by yeasts. mold and

lactic acid bacteria.

  In all cases the raw material must be dried.

  A first solution consists in introducing the boards into dryers immediately after sawing to bring their humidity level below.%; O ideally between. 8 and 19%. For better use, this treatment can be completed by pre-soaking in an insecticide and fungicide, whether it be pentachlorophenol, quaternary ammoniums of copper, fluorine, boron, arsenic, cypermethrin, carbamates, etc. To eliminate sucrose it is necessary to practice the drying of the boards before drying to European standards. This treatment will be carried out in a longitudinal Cen galvanized sheet metal tank of 300xO10x100 cm. mounted on a structure of mechanically welded angles including a drain valve. Planks are immersed in water, separated by plastic separators to facilitate dilution; after a first bath of 2 hours during which the water is stirred by a paddle wheel it is found on boards with a section of 15x100 mm. a reduction of more than 20% in the sucrose level; after the first renewal of the rinse water the rate

  elimination is decreasing; a third wash is sufficient to prevent blue stain.

  -2- This drying can also be done by washing with running water, or by steam entrainment, or by spraying with a suitable solvent, the result being, in

  in all cases, the elimination of at least 20% of the sucrose contained in the boards.

  We have already seen that this drying can be completed, after drying, by a

  fungicide and insecticide treatment.

  Depending on the use, the treatment can be supplemented, after drying, with a tetrakis salt, with alkali metal citrates, with a guanylurea phosphate, with a

  ammonium pentaborate, by halogenated compounds, etc. giving the material a better fireproofing standard.

  Depending on the use, after drying, the treatment can make the material water-repellent

  by impregnating a water repellent of the rnmethylsiloxane or other oligomer type.

  According to the use, after drying, the material can receive a waterproofing and elastic surface treatment of the resin type of PVC and polyvinyl alcohol copolymers. Depending on the use, after drying, the material can be hardened by impregnating urea formaldehyde or phenol formaldehyde or diallyl phthalate or methyl methacrylate, etc.

  Depending on the use, after drying, the material can be used sandwiched between two or more other materials.

  0 The material obtained, with a density of approximately 140 Kgim3, is suitable for all uses where thermal and sound insulation characteristics are required, of good

  fire resistance without toxic release, lightness and solidity as well as an interesting aesthetic aspect.

Claims (9)

  cypermethrin, carbamates, etc.
  3) Material according to claim I, characterized in that the drying can be preceded by a dessevage by immersion in a running water bath or in a tank where the water would be stirred and renewed periodically, or by steam entrainment , or by spraying with a suitable solvent, the result being, in all cases, the elimination of 20%
  at least, sucrose contained in the sap.
  4) Material according to claim 1, characterized in that a treatment, after drying, with tetrakis salts, with alkali metal citrates, with guanylurea phosphate, with ammonium pentaborate, with halogenated compounds, etc. him
  will provide a better standard for fireproofing.
  5) Material according to claim I, characterized in that the insecticide and fungicide treatment can also be carried out after drying, whether it is quaternary ammonium hydroxides of copper, fluorine, boron arsenic, cypermethrin, carbamates, etc. .
6) Material according to claim 1, characterized in that it can be made water repellent, after drying, by impregnating a water repellent of the oligomer type
methylsiloxane, or the like.
  7) Material according to claim 1, characterized in that it can be waterproofed, after drying, by a surface treatment with copolymer resins
PVC and polyvinyl alcohol.
  8) Material according to claim 1, characterized in that it can be hardened, after drying, by an impregnation of urea formaldehyde or phenol formaldehyde or diallyl methyl phthalate or methacrylate, etc.
