Problems solved by technology

[0003] However, in the prior art, in order to improve the thermal stability of the jelly glue, the jelly glue is often modified, and toxic substances such as formaldehyde may be added during the modification process so that the modification reaction can proceed smoothly
Although this type of modified jelly glue has good thermal stability, the toxic substances used in its production process will affect the health of the staff, and the jelly glue made may also contain formaldehyde residues, and long-term exposure will also affect human health.
Moreover, the existing jelly glue is prone to a decrease in the viscosity of the glue in a humid environment, so that the phenomenon of glue opening or non-sticking occurs, which affects the service life of the product

Abstract

The invention relates to the technical field of adhesives, in particular to environmentally friendly jelly glue and a preparation method thereof. The environmentally friendly jelly glue comprises thefollowing raw materials in parts by weight: 15-20 parts of gelatin, 7-15 parts of konjaku flour, 8-12 parts of carragheen, 8-15 parts of an oxidizing agent, 3-5 parts of a penetrating agent, 1-2.5 parts of a defoaming agent, 1-3 parts of an antioxidant, 0.2-1 part of a water-retaining agent, 1-2 parts of soluble metallic salt, 1-6 parts of a pH adjusting agent and 35-50 parts of water. The viscosity of the environmentally friendly jelly glue at the temperature of 60 DEG C is 900-1100 cps, a product produced by the environmentally friendly jelly glue can resist edge warping within 200-400 h inan environment at the temperature of 40-50 DEG C, and glue failure can be avoided within 200-350 h in an environment with the humidity of 90%-95%.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environment-friendly jelly glue and a preparation method thereof. Background technique [0002] Jelly glue is used to make the covers of gift paper boxes, wine boxes, cosmetic boxes, tea boxes, hardcover book cases, photo albums, stamp albums, folders, etc. It can also be used for the production of high-end gift boxes. Since the main component of jelly glue is animal protein, it is a solvent free of benzene and formaldehyde, so it is non-toxic and truly environmentally friendly. It will not pollute food and packaged items. Products produced with jelly glue are not deformed, not easy to mold and foam, and can enhance the stiffness of paper products. In addition to strong viscosity, jelly glue also has moderate softness, which makes hardcover books, cookbooks, dictionaries and dictionaries frequently folded parts difficult to break. [0003] However, in the prior art, in or...
