Embodiment 1
[0018] This embodiment provides a preparation process of a flame-retardant adhesive, which is prepared through the following steps:
[0019] 1) Select the powder flame retardant added to the adhesive and the solvent corresponding to the powder flame retardant, the solvent is toluene, soak the powder flame retardant in the solvent for 12 hours , wherein the volume ratio of the powder flame retardant to the solvent is: flame retardant: solvent=1:3 parts;
[0020] 2) Put the product obtained in 1) into a horizontal sand mill, adjust the pressure of the horizontal sand mill to 4kg, and grind 5 times to obtain a product with a fineness of 2 to 5 μm. The product fineness adopts the fineness board for testing;
[0021] 3) Use a 150-mesh filter to filter the product obtained in step 2), add the filtered product to the adhesive, and stir at the same time, the stirring speed is 400 rpm, and the stirring time is 30 minutes;
[0022] 4) Inject the stirred adhesive containing the powder ...
Embodiment 2
[0025] This embodiment provides a preparation process of a flame-retardant adhesive, which is prepared through the following steps:
[0026] 1) Select the powder flame retardant added to the adhesive and the solvent corresponding to the powder flame retardant, the solvent is ethyl acetate, soak the powder flame retardant in the solvent 12h, wherein the volume ratio of the powder flame retardant to the solvent is: flame retardant: solvent=1:5 parts;
[0027] 2) Put the product obtained in 1) into a horizontal sand mill, adjust the pressure of the horizontal sand mill to 6kg, and grind 5 times to obtain a product with a fineness of 2 to 5 μm. The product fineness adopts the fineness board for testing;
[0028] 3) Use a 400-mesh filter to filter the product obtained in step 2), add the filtered product to the adhesive, and stir at the same time, the stirring speed is 500 rpm, and the stirring time is 40 minutes;
[0029] 4) Inject the stirred adhesive containing the powder flam...
Embodiment 3
[0032] This case provides a preparation process of a flame retardant adhesive, which is obtained through the following steps:
[0033] 1) Select the powder flame retardant added to the adhesive and the solvent corresponding to the powder flame retardant, the solvent is butanone, and soak the powder flame retardant in the solvent 12h, wherein the volume ratio of the powder flame retardant to the solvent is: flame retardant: solvent=1:4 parts;
[0034] 2) Put the product obtained in 1) into a horizontal sand mill, adjust the pressure of the horizontal sand mill to 5 kg, and grind 5 times to obtain a product with a fineness of 2 to 5 μm. The product fineness adopts the fineness board for testing;
[0035] 3) Use a 300-mesh filter to filter the product obtained in step 2), add the filtered product to the adhesive, and stir at the same time, the stirring speed is 500 rpm, and the stirring time is 50 minutes;
[0036] 4) Inject the stirred adhesive containing the powder flame reta...
