Abstract

The invention discloses a moisture-proof cigarette adhesive and a preparation method thereof, relates to the technical field of adhesives, and is provided based on the problems that a conventional cigarette adhesive can cause harm to human body health and does not have moisture-proof ability. The moisture-proof cigarette adhesive is prepared from the following raw materials in parts by weight: 60-65 parts of starch, 3-4 parts of hydrochloric acid, 4-6 parts of sodium hydroxide, 0.5-2 parts of an oxidant, 1-5 parts of a crosslinking agent, 6-8 parts of phenolic resin, 3-5 parts of a nano-inorganic flame retardant, 0.2-0.3 part of a surfactant, 1-3 parts of a mildew preventive, and 160-180 parts of water. The moisture-proof cigarette adhesive has the beneficial effects of low cost, safety, environmental protection, increase of moisture-proof ability and self-extinguishing function of cigarette adhesive cigarette butts.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a moisture-proof cigarette adhesive and a preparation method thereof. Background technique [0002] Cigarette glue mainly has two types: polymer emulsion type and water-soluble type. At present, the polymer emulsion glue used in China is mainly PVAc emulsion and VAE emulsion. When the mouth is in direct contact with a certain temperature, toxic gases will be released during the burning process of the cigarette, which will cause harm to the human body and affect the taste of the cigarette. [0003] Due to the limitations of the structure of traditional starch glue, its binding force will drop sharply in a humid environment. After drying, the starch glue and the product will be debonded, resulting in cigarettes that cannot be used normally. Contents of the invention [0004] The technical problem to be solved by the invention is that the existing cigarette gum will cause harm ...
