Abstract

IMPROVEMENTS MADE TO LIQUID OR SEMI-LIQUID MIXTURES THAT INHIBIT FIRE AND HAVE BACTERICIDAL, ANTI-CORROSIVE, WATERPROOFING AND THERMO-REFRACTORY PROPERTIES. MAXIMUM PROTECTIVE COVERING MATERIAL (MCPM) IS A PRODUCT DERIVED FROM A PROCESS OF CHEMICAL REACTIONS THAT INHIBIT FIRE ON MATERIAL SURFACES WHERE IT IS APPLIED, WITHOUT DEGRADING THEIR DEGREE OF POROSITY OR THEIR ADHESION CHARACTERISTICS. ITS PHYSICAL CONSISTENCY FOR APPLICATION MAY BE LIQUID IN THE FORM OF PAINT OR SEMI-LIQUID IN THE FORM OF BLANC DE TIROL (KIND OF CREPI). DUE TO THE COMPOUNDS WHICH IT IS FORMED, IT GIVES BACTERICIDAL, ANTI-CORROSIVE AND ALSO WATERPROOFING AND THERMO-REFRACTORY PROPERTIES TO THE MENTIONED SURFACES. IT ACTS BY FORMING A REFRACTORY BARRIER WHICH PREVENTS THE IGNITION OF THE TREATED MATERIAL IN CONTACT WITH FLAMES, SINCE ITS TEMPERATURE WILL BE AROUND 60C, RESTRICTING THE INTRODUCTION OF OXYGEN BY FORMATION OF CRYSTALS IN THE INTERMOLECULAR SPACES. THE APPLIED LAYER OF MCPM AND FURTHER FORMING A POLYMER FILM IN CONTACT WITH THE HEAT WHICH OPPOSES THE INTRODUCTION OF THE AIR NECESSARY FOR COMBUSTION.

Description

IMPROVEMENTS IN LIQUID MIXTURES

  OR SEMI-LIQUIDS INHIBITING THE FIRE AND HAVING PROPERTIES

  BACTERICIDES, ANTI-CORROSIVE, WATERPROOFING AND THERMO--

REFRACTORY.

  The applicant has information on processes developed in various parts of the world such as the United States, Great Britain, Germany and other countries, to treat various materials separately by giving them the qualities offered by the MCPM ( Maximum Protective Cover Material), as has been the case with boats, sleepers and poles in contact with the ground, which are treated with products based on creosote, coal or beech, in order to give them bactericidal properties against organisms that usually adhere to the wood by damaging it, such as crustaceans limnoria

  and the molluscs of Banbia and Teredo among others. In addition, various materials

  have been treated with fire retardants, but the

  are not aware of any fire-inhibiting characteristics when applied to surfaces such as ship hulls which, because of the harsh climatic, physical, chemical and biological conditions to which they are exposed, represent a real challenge. Moreover, it is necessary to take into account also the great expense represented by the risk and the losses among those which are exposed in this memoir, in case of absence of adapted protection, even if this results from the sum of partial solutions which, in certain cases, fail to cover all or the majority of such risks as corrosion,

  material deterioration and flammability among others.

  It is for this reason that, in response to the problem, the MCPM (Material Covering Maximum Protection) represents, day after day, an option in the solution of a series of existing needs, in the context of productivity, economy and security in the

  societies of various latitudes of the planet.

DEVELOPMENT

  The main function of the product object of the invention is that of a fire inhibitor, which is obtained by means of two fundamental mechanisms: first, since by its components, the MCPM layer applied to a surface of material (X) forms a real refractory barrier that prevents high temperatures consistent with those of fire flames, which oscillate around 2000 C while those reached by the product (MCPM layer) oscillate around 60 C, it

  It is obvious that the temperature is well below that of the

  with a flame. Second, the other mechanism is to restrict the introduction of oxygen into the MCPM layer, which is achieved by crystal formation in the intermolecular spaces of the MCPM layer and, by formation of polymer film under the effect of heat, which opposes the introduction of the necessary air to

  proper combustion, reducing it to a minimum value.

  The other properties of MCPM are properties inherent to those possessed by the product at the end of the mixing of its components

who react with each other.

COMPOUNDS AND METHOD

N COMPOUNDS QUANTITIES

  1 Vegetable coal 500 g 2 Silica sand 500 g 3 Bentonite 250 g 4 Zinc oxide 500 g Borax 50 g 6 Refractory clay 200 g 7 Calcium carbonate 150 g 8 Refractory concrete 235 g 9 Ammonium sulphate 150 g Sodium monophosphate 200 g Linseed oil 750 ml 12 Unleaded petrol 750 ml Stage I The compounds are dry-blended from 1 to 10, by grinding the charcoal and the siliceous sand, up to the meshes of an optimum sieve for application. desired, - according to the specifications to which the product

  is intended - such as paint or white de-Tirol (sort of plaster).

  Stage 2 To the previous dry mix, add linseed oil (750 ml), so that all components are incorporated into the mix and so

  that it is as homogeneous as possible.

  Stage 3 To the previous mixture 750 l of unleaded gasoline is added

by incorporating it into the mixture.

  Final result In the case of paint, a liquid with a thick consistency, originally gray in color, with a density

from 40 Baumé.

  In the case of Tirol white, its color does not vary, although its consistency is greater than that of the previous mixture, while

being rather semi-liquid.

APPLICATION

  The paint gives a yield of 10 to 12 m 2 of surface with a thickness of 15 microns; in the case of Tirol white, the yield

  is 3 to 4 m2 with 1 cm thick.

  The weight of the objects will be increased, by applying the product (MCPM), a higher percentage, when it is fresh, to the percentage after drying. That is - a piece of plywood 15 x 15 cm x 3 mm, having an original weight of 65 g, whose weight has increased

  about 23% (80 g) with the wet MCPM layer is finally

  increased by about 15.3% (75 g) after drying.

  The drying time depends on the characteristics of the object on which the MCPM is applied, the average time being 72 hours; this time can be reduced by adding to the finished product, and a little before the application, 250 ml of diluent per liter of product, incorporating well

  both preparations. This reduces the drying time by about 50%.

  The product can be applied as a paint with a silk brush or a spray gun (spray) or as white

of Tirol in the corresponding case.

  It should be noted that none of the properties of this product will be

  until it is thoroughly dried after application.

  MATERIALS ON WHICH APPLICATIONS MAY

BE CARRIED OUT

  MCPM can be practically applied to any surface and its use depends in many cases on the creative imagination of those who use it, also taking into consideration the fact that the MCPM changes the physical appearance and in many of

  case the aesthetics of the objects on which the application is made.

  Some of the materials on which the application is

  may be made: - All types of wood or agglomerates Foam rubber - Glass - All categories of plastics and packaging made of plastics - Polystyrenes, polyurethane false ceilings - Glass fibers - Clays, bricks, cement - Any type of metal (including to cover the interior of

automobile bodies).

RANDOM BENEFITS

  - It increases the resistance of some materials as in

  the case of wood protecting it against bursting up to about 30%.

  - It reduces corrosion to a minimum.

  - It avoids the deterioration of certain materials on which certain organisms, such as bacteria, can adhere, by acting

as bactericidal.

  - Its manufacturing cost is relatively low.

  - The compounds are obtained and are produced in the country.

EXAMPLE 2

  We take a piece of plywood 20 cm x 20 cm x 3cm, applying to it all over the surface (both sides and all sides) a layer of MCPM (like a paint) about 3 microns and allowed to dry for 72 hours, then introduced into an electric oven at a temperature of 3000 F for 5 hours,

  without any flame, and without the wood being carbonated

nized.
