Starch-based adhesive with flame resistance function and preparation method thereof

The invention discloses a starch-based adhesive with a flame resistance function. Through the organic combination of starch, kaolin and titanium dioxide, heat is firstly absorbed to form a flame retardant heat resistance residue carbon layer when the temperature is approximately risen to an ignition point, heat is continuously absorbed to form a ceramic-like coating layer, firing heat is reduced to prevent penetration and spreading of flame, the effect of quenching combustion reaction can be realized through the synergistic effect of crysticallized state ammonium polyphosphate, and the flame resistance performance of the adhesive is greatly improved through multipartite synergistic effect; adding of ultrahigh gel degree protein powder can obviously improve the density of the heat resistance residue carbon layer, and improving the formation speed and strength of the ceramic-like coating layer, thereby enhancing the flame retardant class. The adhesive is simple in production technology,obvious in flame resistan
