4 Claims. (cl. 87-17) The art of making glues from vegetable floursmade froxmprotein-bearing materials, such as soya bean, peanut, cottonseed, linseed, 'castor bean, and the like, has been known and has been 5 largely used on account of the .cheapness of the materials, but 'dinicuity has been encountered in making such a glue which does not require the constant attention of an experienced glue-mixer on account 01 the other materials formerly nec- 19 essary to make a-usable glue, such as caustic soda, silicate oi. soda, carbon bisulphide, and'the like, which cannot be put into the glue itself in the dry state but must becaretullymeasured and mixed after the soils. bean flour, or other constituents, have been mixed with water.
I have found that such glues can be made] more highly water-resistant it they are formedwith a water-soluble product of. cellulose. namely viscose, and that they do not require the skill- 20 iul attention of an expert in their preparation. Since these several vegetable meals are all slightly acid and since such acid content would separate the cellulose'in the viscose used. to make an insoluble compound neutralize-the meal before it is used in making the glue. This neutralization 'may be eflected by the suitableuse of any soluble sodium salt, or any alkaline earth materials.
To this neutralized vegetable flour is added a water-soluble product of cellulose, namely. viscose, in the proportion of about 25 to parts or the'viscose 'to 100 parts of the neutralized meal. This viscose contains an excess oi. caustie. in order that it wfll be retained in liquid 35 condition and this excess or caustic'acts as a,
solvent for the meal, while the cellulose in the viscoseactsas a means of increasing its water- 'I'he viscose is prepared under standard directions such as those published by Cross 8: Bevins, using rayon pulp, or other high grade wood pulp, as. a base. Other suitable matcrials's'uch as cottonstraw, can be used it-desired.
The wood, being glued, is slightly acid and co when such a glue, as above described, is applied to the wood, the acids in the wood itseli neutralize. the caustic of the glue and slightly acidiiies the glue line, which is then highly water -resistant. a
The glues are prepared in an aqu ous medium, in suitable proportions, about 250 parts 01 water to 100 parts of neutralized flour usually losicviscosecontaininganexcessotalkaliasa'.
