Description

UNITED STATES PATENT OFFICE LINER FOR SEPARATING ADHESIVE MATERIAL No Drawing. Application March 30, 1937,
Serial No. 133,828
2 Claims.
This invention relates to liners for separating unvulcanized rubber or similarly adhesive sheet material.
In the handling of sheet rubber, rubberized fabrics, and other adhesive materials, sheets of cloth or paper are customarily used to separate the adhesive sheet material. These separating sheets are commonly known as liners. In order to reduce the expense of manufacture and transportation of adhesive plastic materials, it is desirable to provide a liner which is low in initial cost, one which may be used repeatedly, and one which may be readily stripped from the adhesive sheet without injury to the liner or to the plastic sheet.
The principal objects of this invention are to provide a liner having low initial cost, great flexibility, low adhesive properties, and long life.
These and other objects are attained by treating a web of cloth, paper, or other permeable material with an wens dispersion of sodium silicate containing suitable plasticizing agents such as glygzrige, sulfonated oils, soaps, and waxes. The soap preferably is formed during the preparation of thedispersion .by the combination of the oils with the alkali of the sodium silicate, but the soap may be added as an ingredient. The glycerine, being hygroscopic, also prevents excessive drying of the liner.
The waxes not only act as plastlcizing or softening agents, but also reduce the adhesiveness of the composition and reduce the cost thereof.
As an example of a composition which has given very satisfactory results, the following formula may be used:
I") C f7 (CI. 91-68) 7 r Pounds Sodium silicate solution 52 B 65 Glycerine 15 Parafiln wax 15 Oleic acid 4 5 The ingredients are mixed preferably while they are hot. The oleic acid reacts with the alkali of the sodium silicate to form a soap which tends to emulsify the wax. The paraffin wax may be a low priced soft Wax. During drying of the liner the wax melts and forms a coating over the partially dried silicate and prevents successive convolutions of the liner in a roll thereof from sticking to each other. The parafiin wax may be replaced with sulfonated castor oil or similar sulfonated vegetable o Is.
In forming a liner, the sheet material, either in the form of fabric or paper, is passed through a heated bath of the impregnating material, the material remaining in the bath for a sufllcient time to totally or partially impregnate it as desired. After the excess coating material has been drained therefrom, the sheet material is dried and rolled upon itself.
I claim:
1. A separable liner for adhesive material, said liner comprising permeable sheet material impregnated with a composition of water glass mixed with giycerine, paramn wax and olelc acid.
2. The method of preparing a separable liner for adhesive material which comprises mizdng at an elevated temperature water glass with glycerine, paraflln wax and oleic acid, and impregnating permeable sheet material with the resulting composition.
