Problems solved by technology

[0002] Glue is an intermediate that connects two materials. At present, office glue generally has the characteristics of weak cohesive force. Some glues have relatively high water content, which penetrate into paper after use, affecting use, and contain toxic and harmful substances such as benzene and formaldehyde. Substances that can cause harm to the human body during use

Abstract

The invention discloses high-viscosity and low-permeability glue. The high-viscosity and low-permeability glue is prepared from the following raw materials in parts by weight: 20 to 30 parts of gelatin, 30 to 40 parts of shell-lac, 10 to 15 parts of corn starch, 1 to 4 parts of borax, 2 to 5 parts of hydrogen peroxide, 2 to 7 parts of sodium silicate, 0.5 to 1 part of alums and 2 to 5 parts of water, wherein the content of shell-lac resin in the shell-lac is 70 percent to 90 percent. The high-viscosity and low-permeability glue has a strong cohesive force and low water permeability; the gelatin and the shell-lac animal glue are added, and benzene and formaldehyde solvents are not included, so that the high-viscosity and low-permeability glue has no toxin and irritation, is safe and environmentally friendly, and is harmless to human bodies.

Description

technical field [0001] The invention belongs to the field of office supplies, and in particular relates to a high-viscosity and low-permeability glue. Background technique [0002] Glue is an intermediate that connects two materials. At present, office glue generally has the characteristics of weak cohesive force. Some glues have relatively high water content, which penetrate into paper after use, affecting use, and contain toxic and harmful substances such as benzene and formaldehyde. Substances that can cause harm to the human body during use. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a high-viscosity and low-permeability glue, which has strong cohesive force, low water permeability, does not contain solvents such as benzene and formaldehyde, is non-toxic, non-irritating, safe and environmentally friendly, and is safe and environmentally friendly. Physically harmless. [0004] The technical solution o...
