Embodiment 1
[0018] A method for evenly and quickly bonding between layers of carbon fiber thermal insulation hard felt, comprising the following steps:
[0019] Step 1: Configure the adhesive 2 according to the following weight ratio: diluent: resin: graphite powder = 65:25:10, stir continuously in the mixing tank 1 for 20 minutes, put it into the rubber bucket 4 for use, and the diluent has a concentration of 95 % industrial alcohol, when the temperature is lower than 10 ℃, it must be equipped with a constant temperature water bath heating device;
[0020] The second step: adjust the viscosity of the adhesive 2: the viscosity is controlled at 1500cps;
[0021] Step 3: At the glue spraying site, use the pneumatic graphite emulsion spray gun 5 to spray the adhesive glue on the carbon fiber insulation hard felt layer 7, first connect the compressed air connector of the graphite emulsion spray gun 5, and place the other port on the glue In barrel 4, the spray angle of the spray gun is 75 de...
