preparation example Construction
[0046] The invention provides a method for preparing a foam, comprising:
[0047] Step 1, extruding the low-foaming material to form low-foaming granules, and extruding the high-foaming material to form high-foaming granules;
[0048] Step 2, the low-foaming particles described in step 1 enter the processing equipment through the low-foaming material inlet of the processing equipment (such as an extruder), and the heating temperature of the processing equipment is 120-200 ° C;
[0049] Step 3, when the low-foaming particles are heated in the processing equipment to form a molten state, the high-foaming particles are added into the processing equipment through the high-foaming material inlet of the processing equipment, and heated to 160-260°C;
[0050] Step 4, because the melting point of the high-foaming material is higher than that of the low-foaming material, the high-foaming particles do not melt in the melting temperature range of the low-foaming material, but are blended...
Embodiment approach 1
[0058] Embodiment 1: Take 100 parts of low-density polyethylene, 10 parts of expanded graphite, 1 part of red phosphorus, 1 part of aluminum hydroxide, 10 parts of foaming agent ADCA (alias AC, ADC) and 0.8 parts of zinc oxide from the low-foaming material , 0.6 part of antioxidant (1010); 200 parts of high-density polyethylene and 80 parts of foaming agent ADCA are taken from the high-foaming material, and the foam is obtained according to the preparation method of the above-mentioned foam.
Embodiment approach 2
[0059] Embodiment 2: Take 100 parts of low-density polyethylene, 10 parts of expanded graphite, 1 part of red phosphorus, 1 part of aluminum hydroxide, 10 parts of foaming agent ADCA, 0.8 parts of zinc oxide, and an antioxidant (1010) from the low-foaming material 0.6 part; 200 parts of high-density polyethylene, 5 parts of expanded graphite, 3 parts of red phosphorus, 2 parts of aluminum hydroxide, and 80 parts of foaming agent ADCA are taken from the high-foaming material, and the foam is prepared according to the preparation method of the above-mentioned foam .
