Example Embodiment
[0027] Example 1
[0028] Step 1 First, mix low-density polyethylene (MI0.6) and azodicarbonamide at a ratio of 2:1, low-density polyethylene (MI0.6) and dicumyl peroxide at a ratio of 19:1, low-density polyethylene (MI0.6) and dicumyl peroxide at a ratio of 2:1. Density polyethylene (MI0.6), decabromodiphenyl ether and antimony trioxide are made into foaming agent masterbatch, crosslinking agent masterbatch, and crosslinking agent masterbatch at the ratio of 4:2.5:1 with an internal mixer and an open mill. Flame retardant masterbatch. The temperature of banbury and open refining is controlled at 90℃-110℃.
[0029] Step 2: 26.56 parts by weight of low-density polyethylene (MI0.6), 48 parts by weight of foaming agent masterbatch, 13 parts by weight of crosslinking agent masterbatch, 9.64 parts by weight of flame retardant masterbatch, and universal black masterbatch (general) 0.8 parts by weight and 2 parts by weight of the antibacterial and antifungal masterbatch are mixed evenly ...
Example Embodiment
[0034] Example 2
[0035] Step 1 is the same as Example 1
[0036] Step 2 The proportions of various pellets contained in the mixture are changed to: 24.6 parts by weight of low-density polyethylene, 58 parts by weight of foaming agent masterbatch, 15 parts by weight of crosslinking agent masterbatch, 0.4 parts by weight of black color masterbatch, antibacterial 2 parts by weight of anti-mold masterbatch. No flame retardant masterbatch is added to the mixture.
[0037] Step 3 The extrusion conditions are the same as in Example 1, and the sheet material specifications are changed to 1.2 mm in thickness and 440 mm in width.
[0038] Step 4 The temperatures of the first, second and third stages of the foaming furnace were changed to 164°C, 187°C and 223°C, respectively. The conveying speed of the sheet in the furnace is 4.5 m / min.
[0039] Step 5 is the same as Example 1, but the width of the product obtained is 1200mm, the thickness is 3.0-3.2mm, and the density is 37kg / m 3 .
