The invention also provides the application of the above EVA rubber and plastic composition as a foamed product, and the package 12 201024360 comprises the following steps: Step 1: installing a matching mold for the product to be processed; Step 2: putting the rubber and plastic composition particles into automatic Ship injection machine, model SC-906L2 〇Step 3: The set temperature of the injection machine is Π7~183 aC, the vulcanization time is 220 seconds~240 seconds, if the injection machine temperature is 178 qC, 18〇吒 or 182吒, the vulcanization time respectively 240 seconds, 230 seconds or 220 seconds; ® Step 4: Set the shooting temperature of the injection machine to one of 82, 83, 85, 87 QC, set the smashing pressure and the minimum injection speed: 6 〇 bar, 2 mm /s ; 65bar, 2. 66mm / s; 70bar, 2. 83 coffee / s; 75bar, 3 coffee / s; or 80 bar, 3 · 17 coffee / s; for example, 'shooting machine shooting temperature is 82 SC shot The pressure is 60 bar, the minimum injection speed is 2 coffee / s; Step 5, use the wind to grab the mold clean, spray the appropriate amount of mold release water; Step six, use the wind to blow dry mold mold release water, inject the required materials Dong, mold clamping; ® Step 7. After the mold is opened, the finished product is quickly taken out and placed on the steamed bread to completely cool. The invention makes the sun visor, the cool hat, the mobile phone sleeve and the like made by using the EVA rubber composition by the reasonable ratio of the foaming agent, the active agent, the lubricant and the flow agent in the composition, and is soft, light and non-toxic. Environmentally friendly and low cost. The present invention is not limited to the above-described preferred embodiments, and it should be understood that any structural changes made by the present invention, which are the same or similar to the present invention, are within the scope of the present invention.
