Title: Improvements in or relating to the protective surface treatment of zinc, zinc coated and zinc alloy articles
IPC: C23C22/30
Filed: 1944-04-20
Abstract: Protective surface films are produced on articles made of, or coated with, zinc or zinc alloys by treatment with an aqueous chromicsulphuric acid mixture containing prior to use, a proportion of the chromium in the trivalent condition, the latter preferably being produced by the addition of a reducing agent which does not introduce an undesirable foreign metal into the mixture such as an aldehyde or a sugar or an inorganic substance such as sulphur dioxide or an alkali sulphite, hydrosulphite or hypophosphite.  To prevent over-reduction in the mixture, a proportion of an oxidising agent which does not introduce an undesirable foreign metal into the solution and which is sufficient to convert only part of the trivalent chromium into the hexavalent form is added.  Example of such an agent is an alkali nitrate, nitrite, chlorate, perchlorate, perborate or persulphate. The mixture may also contain a wetting agent such as a sulphonated fatty alcohol or ester and also an acid inhibitor such as thioureas or quinoline compounds.  When the materials are used in the dry form for preparation of the solution, an alkali bisulphate is used instead of sulphuric acid and the chromic acid p  in the form of an alkali chromate or bichromate and the reducing, and wetting agents and also the inhibitor in the solid form.  Zinc alloys containing not less than 85 per cent. of zinc and copper and/or aluminium are referred to.

Title: A process for the production of condensation products from formaldehyde and urea
IPC: C08L61/24
Filed: 1937-03-18
Abstract: A resinous fusible product is obtained by mixing urea with solid, polymeric formaldehyde at ordinary temperature, without the addition of water or other liquid, and maintaining the mixture at a temperature not above 35 DEG  C. until the smell of formaldehyde has substantially disappeared.  To obtain a hardenable resin, 70--90 parts by weight of formaldehyde per 100 parts of urea may be employed.  Condensation may be effected in the presence of catalysts, and urea may be partly replaced by thiourea or other compound reacting with formaldehyde.  The products may be worked up alone or with suitable additions into lacquers, coatings, laminated sheets, shaped articles or pressed masses.  In examples: (1) urea and paraformaldehyde, are mixed with zinc oxide by grinding in a ball mill and the mixture stored for about 8 days at 30 DEG  C.; (2) urea, paraformaldehyde and citric acid are similarly treated; (3) a glycerine-phthalic acid resin is added to the components in (1); (4) urea and paraformaldehyde are finely mixed in a ball mill, stored for 4 days at 25 DEG  C., and the mass mixed with wood meal and heated for 2 hours to 75 DEG  C. to produce a moulding mixture; (5) urea, formaldehyde and calcium hydroxide are similarly worked up with alpha cellulose pulp; (6) urea, trioxymethylene, a light-coloured phenol resin and tartaric acid are mixed in a ball mill, stored for 3 days at 20 DEG  C., and then mixed with lithopone and zinc oxide; the lightcoloured phenol resin is obtained by mixing 100 g. phenol, 120 g. 40 per cent formaldehyde and 4 g. anhydrous sodium carbonate and heating to boiling for 15 minutes, and then neutralizing with phosphoric acid and vaporizing until a hard resin is obtained.
