Patent GB-225953-A (GB)
Title: Improvements in or relating to adhesives and the manufacture thereof
IPC: C09J161/00
Filed: 1923-09-15
Abstract: An adhesive or cement comprises a mixture of an artificial resin and a gelatine or glue-like proteid that has been rendered liquid or non-gelatinous by partial hydrolysis; other proteid materials, such as blood albumin or casein, may be added, and where such addition is made the liquid glue may be replaced by other colloidal materials such as oil emulsions, glycerosols, glucososols, and sols prepared from gum arabic, dextrine, starch, agar-agar and other seaweeds, soaps, resinates, linoleates, and indiarubber.  A suitable artificial resin is prepared by condensing phenols, naphthols, or their homologues with aldehydes in presence of a hypochlorite as an accelerator. The non-gelatinous or liquid glue may be prepared by soaking glue in dilute acids until it is dissolved and heating the solution on the water-bath, after which excess of acid may be neutralized by means of alkalies, ammonia, or organic bases.  An acid such as phosphoric or hydrobromic acid, the salts of which are of use as fire-proofing materials, may be employed and the excess neutralized with zinc oxide, the composition prepared with glue so treated rendering fire-proof the material treated therewith. Alternatively, the liquid glue may be prepared by heating glue with water under pressure for several hours, and this process may be assisted by the addition of small amounts of low-boiling liquids, such as methyl alcohol or acetone, or of acid salts of the alkalies, such as sodium bicarbonate; a number of other suitable accelerators are mentioned also.  Another alternative method of preparing liquid glue consists in heating glue powder on the water-bath with a 10-20 per cent solution of zinc chloride or calcium chloride.  A further alternative method consists in mixing glue, without heating, with a variety of specified substances including oils, starch, ammonia, and amyl acetate.  An example is given describing the admixture of liquid glue with an artificial resin to produce an adhesive suitable for use in making plywood, the wood being subjected, for example, to a pressure of 300 lb. to the square inch at a temperature of 110 DEG -120 DEG  C. Another example shows the addition of the above ingredients of blood albumen obtained in homogeneous solution by means of carbamide.  Other examples describe the incorporation with an artificial resin of:-indiarubber and glue; factis prepared from china-wood oil or linseed oil and glue; soap and glue; starch and blood albumin; gum arabic and blood albumin.  The products may be used in making cardboard or in cementing china or glass, and their properties may be modified by the addition of powders such as zinc oxide, kieselguhr, graphite, or wood dust.ALSO:The condensation of phenols, naphthols, or their homologues with aldehydes is carried out in presence of a hypochlorite as an accelerator.
