Embodiment 1-10
[0024] Example 1-10: Preparation of a flexible flame-retardant rubber curtain with high strength, long life and good visual effect.
[0025] The first step: see Table 1, 3, according to each embodiment, natural rubber of different weights, zinc oxide, stearic acid, white carbon black, titanium dioxide, flame retardant, softener are placed in a closed rubber mixer , Mixed rubber for 15 minutes at 100°C to prepare mixed rubber.
[0026] For example, for Example 1, the parts by weight of the following components are: natural rubber 100phr, zinc oxide 4phr, stearic acid 2phr, white carbon black 20phr, titanium dioxide 10phr, flame retardant (being decabromodiphenylethylene Alkane) 25phr, softener 15phr.
[0027] Second step: in the mixed rubber prepared in the first step, add vulcanizing agent and accelerator in different parts by weight in Table 1 and 3 respectively, and place it in an open rubber mixer for re-milling, and re-milling for 5 After the first pass, the film will be...
