Title: Improvements in compositions of matter containing synthetic resins
Filed: 1932-04-27
Abstract: Liquid or solid compositions, suitable for use in the production of varnishes or of moulded articles such as gramophone records, comprise animal or vegetable oils together with halogenated synthetic resins of the phenol aldehyde or phenol ketone type or synthetic resins of the diphenylol-propane aldehyde or diphenylol-propane ketone type. When cellulose derivatives are present, they are added in an amount not greater than 10 per cent of the weight of the synthetic resin. Suitable oils are linseed, castor, perilla, poppy-seed, rape, sesame, tung and soya bean oil, raw, boiled or blown.  Non-drying oils such as neat's foot or whale oil may be used, and more than one oil and more than one resin may be incorporated.  The raw materials for making the p  synthetic resin, or intermediate products of the resin-formation reaction, may be mixed with the oil, and the reaction then carried to completion, or the resin itself may be ground with the oil, or mixed in solution therewith, the solvent being distilled off, if desired.  Other constituents which may be added include natural, semi-synthetic, or other synthetic resins, cellulose esters and ethers, solvents, diluents, plasticizers and fire-proofing agents such as sodium tungstate or phosphate.  Suitable fillers include wood-pulp, wood-meal, cotton flock, silica, lithopone, china clay, slate dust, asbestos and zinc oxide.  Waxes may be added to the extent of 1-2 per cent, and lubricants, such as stearic acid or certain stearates, may be present.  As examples: (1) A varnish is made by mixing 10 parts of a diphenylol-propane formaldehyde resin with 40 parts of boiled linseed oil, 2 parts of lead cobalt drier, 15 parts of turpentine and 15 parts of petrol.  (2) A composition suitable for moulding gramophone records consists of 34 parts of diphenylol-propane formaldehyde resin, 20 parts of diphenylol-propane acetone resin, 20 parts of castor oil, 10 parts of perilla oil and 60 parts of a filler.  Specifications 299,065, 299,066, 299,067 and 313,133, [all in Class 95, Paints &c.], are referred to.ALSO:Liquid or solid compositions, suitable for use in the production of varnishes or of moulded articles such as gramophone records, comprise animal or vegetable oils together with halogenated synthetic resins of the phenol aldehyde or phenol ketone type or synthetic resins of the diphenylol-propane aldehyde or diphenylol-propane ketone type.
