Problems solved by technology

[0002] At present, the polyethylene foam materials produced on the market are generally not very good because of their low magnification, and the stability of the products is generally not very good, and they cannot play well in shock absorption and noise reduction. Moreover, the production process of most of these polyethylene foam materials is relatively complicated, and the production cost is relatively high, which affects the profit margin of the enterprise.

Embodiment 1

[0016] Embodiment 1: First take by weight percentage: 10% EPDM, 50% polyethylene, 5% stearic acid, 10% zinc oxide and 25% nitrogen dicarbonamide, then first 10% Put the EPDM into the pressurized internal mixing kneader for internal mixing, control the temperature in the mixing process at 80 degrees, make the EPDM in a hot melt state, and then put 50% polyethylene into the kneader to make the polyethylene Ethylene was kneaded in it for 10 minutes, then 5% stearic acid was added to continue kneading for 10 minutes, 10% zinc oxide was added to knead for 5 minutes, and 25% nitrogen dicarbonamide was added to continue kneading for 15 minutes , stop mixing, take out the mixed material, and then pour the kneaded mixed material into the double-pull granulator with a bucket elevator for granulation. After the granulation is completed, put the granules into the extruder to extrude. The extruded sheet is calendered by the calender at the same time, and finally the calendered sheet enters...

Embodiment 2

[0017] Embodiment 2: first take by weight percentage: 15% EPDM, 45% polyethylene, 8% stearic acid, 5% zinc oxide and 27% nitrogen diformamide, then first 15% Put the EPDM into the pressurized internal mixing kneader for internal mixing, control the temperature of the mixing process at 90 degrees, make the EPDM in a hot melt state, and then put 45% polyethylene into the kneader to make the polyethylene Ethylene was kneaded in it for 12 minutes, then 8% stearic acid was added to continue kneading for 5 minutes, 5% zinc oxide was added to knead for 8 minutes, and finally 27% nitrogen diformamide was added to knead for 18 minutes , stop mixing, take out the mixed material, and then pour the kneaded mixed material into the double-pull granulator with a bucket elevator for granulation. After the granulation is completed, put the granules into the extruder to extrude. The extruded sheet is calendered by the calender at the same time, and finally the calendered sheet enters the automa...

Embodiment 3

[0018] Embodiment 3: first take by weight percentage: 20% EPDM, 40% polyethylene, 2% stearic acid, 5% zinc oxide and 33% nitrogen diformamide, then first 20% Put the EPDM into the pressurized internal mixing kneader for internal mixing, control the temperature in the mixing process at 95 degrees, make the EPDM in a hot melt state, and then put 40% polyethylene into the kneader to make the polyethylene Ethylene was kneaded in it for 13 minutes, then 2% stearic acid was added to continue kneading for 5 minutes, 5% zinc oxide was added to knead for 7 minutes, and finally 33% nitrogen diformamide was added to knead for 17 minutes , stop mixing, take out the mixed material, and then pour the kneaded mixed material into the double-pull granulator with a bucket elevator for granulation. After the granulation is completed, put the granules into the extruder to extrude.

Abstract

The invention discloses a polyethylene high-ratio foamed material which comprises the following components in percentage by weight: 5-30% of ethylene propylene diene monomer, 30-70% of polyethylene, 0.3-15% of stearic acid, 1-20% of zinc oxide and 20-40% of azodicarbonamide. The invention also discloses a preparation method of the polyethylene high-ratio foamed material, which comprises the following steps: proportionally extracting ethylene propylene diene monomer, polyethylene, stearic acid, zinc oxide and azodicarbonamide, sequentially putting the components into a kneader to carry out compounding, granulating the kneaded compounding material, calendering the granules, and finally, cutting the calendered sheet. The product disclosed by the invention has favorable sealability, and can better implement shock absorption and noise reduction; and the whole technical process is simple and easy to operate, and reduces abundant technical cost.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a polyethylene high-magnification foaming material and a preparation method thereof. Background technique [0002] At present, the polyethylene foam materials produced on the market are generally not very good because of their low magnification, and the stability of the products is generally not very good, and they cannot play well in shock absorption and noise reduction. Moreover, the production process of most of these polyethylene foam materials is relatively complicated, and the production cost is relatively high, which affects the profit margin of the enterprise. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a polyethylene high-magnification foaming material for the deficiencies of the prior art. [0004] Another object of the present invention is to provide a method for preparing the above-mentioned polyethyle...
