Abstract

The invention discloses a nano flame retardant starch cigarette adhesive and a preparation method thereof, relates to the technical field of adhesives, and is provided based on the problem that conventional cigarette adhesive cigarette butts do not have a fast self-extinguishing function. The nano flame retardant starch cigarette adhesive is prepared from the following raw materials in parts by weight: 50-55 parts of starch, 3-5 parts of nano-magnesium hydroxide, 1.5-3 parts of an oxidant, 4-6 parts of a gelatinizer, 0.2-0.4 part of a preservative, 0.1-0.2 part of a surfactant, 0.1-0.2 part ofa fungicide, and 140-150 parts of water. The nano flame retardant starch cigarette adhesive has the beneficial effects that cigarette adhesive cigarette butts have the advantages of self extinguishing function, safety, environmental protection and no toxicity.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a nano flame-retardant starch cigarette glue and a preparation method thereof. Background technique [0002] With the rapid development of economy and society, large-scale fire accidents are becoming more and more frequent. The fire brought endless disasters to the people, but also sounded the alarm to the society. my country is the largest cigarette producer in the world. There are many fires caused by smoking. The surface temperature of the burning cigarette butt is 200-300 ℃. The temperature is 700-800°C, which is significantly higher than the ignition point of other combustible materials. For example, the burning point of paper is 130-250°C, and the burning point of charcoal is 320-400°C. The burning time of a cigarette is 4-15 minutes, and the leftover cigarette can generally continue to burn for 1-4 minutes. During this time period, many flammable items can be ignited. ...
