This layer of the roll IIlc, between rotary brushes "in and IBb for cleaning ofi excess mica. These brushes are located in the suction housing 9 which facilitates the removal of the surplus mica. The completed sheet then passes to the windup roll as indicated.
In Figure 8, the goods ar passed through four times. The first coatis applied on the face and on the back without mica, and the suceeding coats are applied with mica.
In- Figure 9, the textile material is impregnated in a bath of the coating lacquer so that the entire coating is applied to both sides in one operation, and the mica is dusted on the goods before-it is dried.
The temperature in the drier's is approximately 180 Fahrenheit. There is considerable air circulation. About 1400 cubic feet of air is withdrawn from each machine per minute, and an equivalent amount of fresh air is supplied so it can come in and mingle with the air currents on the inside of the drier.
LAOQUER The formulas may be varied for the lacquer while following the principle of this invention. Broadly speaking, the lacquer consists of a nitrocellulose body associated with suitable solvents, thinners and diluents; a resinous plasticizer,
' preferably of the alkyd type, and finally, a
softener. The following are some typical examples of such lacquers.
Example 1 Parts byweight Cellulose nitrate 12.7 Butyl acetyl ricinoleate 15.3 Paraplexf 12.7 Ethyl acetate 22.9 Alcohol 17.8 Troluoil 10.2 Toluol- 8.4
Example 2 Parts by weight Nitro cellulose 12.5 Maleic acid, ethylene glycol, castor oil,
res I 17.5 Methyl ricinoleate 15.0 Toluol 5.0 Ethyl acetate 22.5 Alcohol- I 15.0 Petroleum thinner 12.5
Paocnss The process consists of impregnating and coating the textile material, then applying the mica either directly or with another coating of lacquer, or upon a second coating of lacquer and thereafter removing the surplus mica before the coatings dry, or optionally after they dry. After the removal of the mica, the resulting product is thoroughly dried by the means and the temperatures heretofore indicated.
The preferable procedure is to apply the mica after the coating. It will be understood that in place of mica any pigment, cellulose flock, or other material of equivalent character may be employed. The use of the mica permits a softer formula than would be possible if it were not present, since it absorbs the slight tackiness right on the surface of the coating. The mica also protects the fabric from the light. Any plasticizer which will remain'inthe nitrocellulose and not tend to exude from the film at a slightly elevated temperature can be employed. The solvents can be adjusted and changed to varying formulas as in other lacquer mixtures. It should be emphasized that one of the principal features of the invention is to provide a thoroughly worked in mica coating, evenly distributed, with the surplus removed to form a non-adherent smooth surface of pleasing appearance, without interfering with the plasticity or flexibility or life of the underlying coating and fabric.
It will be understood that we desire to comprehend within our invention such modifications as may be necessary to adapt it to varying conditions and uses.
Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is:
1. A new article of manufacture for use as a flexible waterproofing lacquer composition consisting of:
Parts by weight Cellulose nitrate 12.7 Butyl acetyl ricinoleate 15.3 Sebacic acid-glycerol resin 12.7
a solvent, and comminuted mica.
2. A new article of manufacture for use as a flexible waterproofing lacquer composition consisting of:
and comminuted mica.
3. A new article of manufacture for use as a flexible waterproofing lacquer-composition consisting of Parts by weight Cellulose nitrate 12.7 Butyl acetyl ricinoleate 15.3 Sebacic acid-glycerol resin 12.7 Ethyl acetate 22.9
a solvent and comminuted mica.
