Hot melt shoe adhesive formula

Formula 1
Dimethyl terephthalate      0.9
Dimethyl decanoate 0.05
Dimethyl phthalate     0.05
Ethylene glycol    1.5
Preparation method
The materials were mixed and cobalt acetate was added to give a total cobalt content of 125 ppm . The reaction is stirred at a temperature of 50 to 225 °C for 4 to 8 hours. Under reduced pressure, nitrogen was passed through the mixture so that the vapor pressure was maintained at 1 mmHg, the temperature was raised from 225C to 250C , and stirred for 6 hours.
Formula 2
Dimethyl terephthalate      87.30
Dimethyl isocyanate 87.30
Dimethyl sebacate 23.00
1 , 4- butanediol    135.00
Lead oxide 0.45
Preparation method
Each batch was mixed in the reactor. The mixture was heated to 150[ deg.] C. under nitrogen. Methanol is distilled off through the glass-filled column. The steam temperature is controlled at 66 °C to ensure that the methanol is distilled out separately. When 64 parts of methanol were distilled off, the butanediol was distilled off by heating at atmospheric pressure and nitrogen at 250 °C. When butanediol was no longer distilled off, it was gradually reduced to 1 mm Hg for distillation. When 45 parts of butanediol were distilled off, the reaction was stopped.
For bonding soles and uppers.
Recipe 3
Thermoplastic copolyester resin 100
Indian red powder dye (iron oxide powder) 1
Preparation method
0.175 mole of isobutyl phthalate, 0.825 mol of 1, 4-butylene terephthalate and the amount of the reaction, can be prepared copolyester (a melting point of 194 ℃). The copolyester was ground into a powder of 170 mesh, and the Indian red powder was mixed to obtain the product. Shoe bonding is performed under hot air flow conditions.
Formula 4
Acetate butyrate (ethyl 13 %, butyl 37 %) 55
Plasticizer NP?01 (neopentyl glycol polymer) 25
Filler resin     14.5
Polyvinyl alcohol modified resin    5
Phosphite (stabilizer) 0.5
Preparation method
well mixed.
