Embodiment 1
[0067] See Figure 1-3 , a bionic bra with the function of natural sterilization and health-care breast protection, comprising a cup part 1, the cup part 1 includes a heart 11 and cups 12 symmetrically connected to both sides of the heart 11, the cup 12 includes a The first latex layer 121, the upright cotton layer 122 and the second latex layer 124 that are arranged in sequence, the rubber net layer 123 is arranged between the described upright cotton layer 122 and the second latex layer 124, and the rubber net layer 123 is set On the side close to the chicken heart 11 , a hand pushing area 125 protrudes from the side of the upright cotton layer 122 away from the chicken heart 11 .
[0068] The area of the rubber mesh layer 123 is 1 / 4 to 3 / 5 of the area of the cup 12 .
[0069] The thicknesses of the first latex layer 121 and the second latex layer 124 are both 1.5-5mm.
[0070] The hand pushing area 125 includes several hand pushing pieces 1251 , and the hand pushing p...
Embodiment 2
[0072] The difference between this embodiment and embodiment 1 is:
[0073] The glue mesh layer 123 is a silica gel mesh layer 123, the thickness of the glue mesh layer 123 is 1-3mm, and the mesh density of the glue mesh layer 123 is 18-40 / cm 2 .
[0074] Both the first latex layer 121 and the second latex layer 124 are provided with a plurality of air holes that run through the inner and outer surfaces thereof, the diameter of the air holes is 0.15-0.95mm, and the distribution density of the air holes is 75-135 / dm 2 .
[0075] The volumes of the several hand pushers 1251 increase sequentially from top to bottom.
[0076] The raised height of the hand-push area 125 is 0.5-3.2 mm.
Embodiment 3
[0078] The difference between this embodiment and embodiment 1 or embodiment 2 is:
[0079] The first latex layer 121 and the second latex layer 124 all include the following raw materials in parts by weight:
[0080]
[0081] The crosslinking agent is dicumyl peroxide; the foaming agent is diisopropyl azodicarboxylate; and the vulcanization accelerator is tetramethylthiuram monosulfide.
[0082] The thickener is methyl cellulose; the mixing ratio of the natural latex solution, methyl methacrylate, sodium alginate and xanthan gum is 16:1:1:2; and the solvent is ethanol.
[0083] The preparation method of described first latex layer 121 and the second latex layer 124 comprises the steps:
[0084] A. Add methyl methacrylate, zinc oxide, zinc stearate and crosslinking agent to the natural latex solution in parts by weight, stir at 20°C for 20 minutes, then gradually add sodium alginate, xanthan gum and vulcanization accelerator and solvent, stirred at 25°C for 20 minutes, an...
