Abstract
The invention provides corn starch glue. The corn starch glue comprises the following components in parts by weight: 50-60 parts of corn starch, 2.5-3.0 parts of hydrogen peroxide, 5-6 parts of caustic soda, 3.5-4.5 parts of urea resin glue, 0.005-0.006 part of ferrous sulfate, 1-1.2 parts of sodium thiosulfate and 450-550 parts of water. The corn starch glue provided by the invention is scientific and reasonable in formula, and the starch is oxidized by utilizing an oxidizing agent, so that the adhesive strength, antiseptic ability and mildew resistance of the starch are improved. Moreover, through the oxidation, the polymerization degree of the starch molecules can be reduced, so as to shorten the molecular chain and enable the prepared binding agent to be good in fluidity.
Description
Technical field
The present invention relates to a kind of viscose glue technical field, be specifically related to Corn Starch Glue.
Background technology
Corn Starch Glue is the binding agent of a kind of environmental type, covers whole paper wrapper and paper products field,
