Abstract
The invention discloses a paper-use low temperature EVA (ethylene-vinyl acetate copolymer) hot melt adhesive formulation and a preparation process thereof, and relates to an adhesive which mainly includes the following components: 25 to 29 parts of EVA resin, 2 to 5 parts of low molecular weight polyethylene, 0.7 to 1 part of a catalyst, 1 to 5 parts of hydrochloric acid, 0.7 to 1 part of a tackifier, 2 to 4 parts of calcium carbonate, 20 to 25 parts of thermoplastic phenolic resin and 10 to 13 parts of dibutyl phthalate. The EVA resin and the thermoplastic phenolic resin are stirred for mixing, meanwhile the catalyst is added for complete mixing at the high temperature over 90 DEG C; then the tackifier is added for stirring for 20 minutes, then the catalyst and the calcium carbonate are heated and stirred, the temperature is controlled at 120 DEG C for even stirring and complete dissolving, and the hydrochloric acid is added to regulate the pH value to be 7-8 to obtain the polysiloxane pressure sensitive adhesive. The hot melt adhesive has the characteristics of being non-toxic, non-flammable, simple in process, good in property and cheap in price, wide in purpose, and strong in practicability.
