HEAT-INSULATING COMPOUNDS AND PROCESS OF PRODUCING SAME.
No Drawing.
T0 all'wkom it may concern:
Be it known that I, CoRNELIs JoHANNEs BEINDORFF, a subject of the Queen of the Netherlands, residing at The Hague, in the Netherlands, have invented certain new and useful Improvements in Heat-Insulating Compounds and Processes of Producing Same, of which the following is a specification.
This invention relates to a heat-insulating compound for boilers, pipes, roofs and the like, and to a process of producing the same.
Oneof the objects of the present invention is to provide a heat-insulating compound for boilers, steam pipes, roofs, etc., which has a greater heat insulating power than the substances used up to the present time, such as magnesia.
A further object is to provide a process of producing the aforesaid compound.
The insulating materials generally used at present consist of one or more ofthe following. substances: infusorial earth, magnesia, asbestos fiber, cork and saw-dust. These substances are intended to form a great number of spaces in which the air is inclosed for the purpose of insulating the heat. When not incombustible the substancesused are made fireproof by adding a substance such as alum, borax, etc. When asbestos fiber is .used in considerable guantity it diminishes the insulating capacity of the mass. The same is the case with cork and saw-dust.
My present invention is characterized by the feature that as a filling material there is useda substance which possesses a very 1 great insulating power while its use does not possess the above-mentioned draw-back, but on the contrary increases the insulating capacityin a high degree. 0
it has been proved that by using woodpulp paper or a similar wood-pulp in a certain proportion with other substances a material can be obtained which has a very great insulating power and which, by the addition of a small quantlty of res 1n possesses a capacity of adherence which is much greater than that of the insulatmg materlals used up till the present time. The great Specification of Letters Patent.
lPaiteintedJuly &, 1%16.
Application filed December 22, 1914. Serial No. 878,588.
heat-insulating capacity is due to the special porosity which is much greater than that of the insulating compounds heretofore known, including magnesia.
Coatings prepared according to this invention do not require to be secured by means of coverings of linen or the like. The
adhesion that is maintained under great heat as well as cold is so firm that theinsulating compound may be applied to ironroof coverings without any speclal means tosaw-dust, or other filling substance, 11 per.
cent.; resin, 2 per cent.
The above proportions may be widely varied, the proportions given serving simply as an example. For instance, I might employ from 10 to 30 per cent. of infusorial earth; 10 to 30 per cent. of alum; 20 to per cent. of woodpulp paper; 10 to 25 per cent. of fine chalk; 5 to 20 per cent. of sawdust; and 12; to 6 per cent. of resin.
In the caseof applying the insulating material at a high temperature, for instance 400 degrees centigrade, it is to be noted that the quantity of infusorial earth -must be increased with the total weight of the insulating mass.
The process maybe carried out in the following manner: The wood pulp paper, or wood pulp together with the resin are very finely ground; the other substances are also mixed together in a suitable mixing device. Afterward the finely divided wood pulp paper and the resin are added to and mixed with the other substances, water being simultaneously sprinkled on the mass.
What I claim is I 1. A heat-insulating compound for use'as dust and resin.
2. The hereindescribed process of producing aheat-insulating compound which consists in forming two mixtures, one composed of Wood pulp paper and resin, and the other,
composed of infusorial earth, alum, chalk end sew-dust, and then mixing the first mentioned mixture with the other While Water is 16 simultaneously sprinkled on the mass.
