The self-adhesive type silica gel bra mold cup is prepared by directly coating hot melt adhesive or pressure-sensitive adhesive on the surface of a commercially available Liquid Silicone Rubber (LSR) serving as a main material.
The self-adhesive silica gel bra mold cup prepared by the above embodiments 1-2 is compared with the self-adhesive silica gel bra mold cup prepared by the comparative example in performance, as shown in table 1:
TABLE 1
The self-adhesive silica gel bra mold cups prepared in the embodiments 1 and 2 have high hardness, and the self-adhesive silica gel bra mold cups prepared in the comparative examples have lower hardness and are softer; the self-adhesive silica gel bra mold cups prepared in the embodiments 1 and 2 have good shaping effect, are not easy to deform in the stretching process, can be better attached to the skin, and can maintain a better gathering effect of the breast, while the self-adhesive silica gel bra mold cups prepared in the comparative example are easy to deform, are softer and have a poor gathering effect; the self-adhesive silica gel bra mold cup prepared in the embodiment 1 and the embodiment 2 is combined with the intermediate connecting layer, so that the adhesive layer can not fall off and can keep 6 months of viscosity, and the self-adhesive silica gel bra mold cup bonding medium prepared in the comparative example is directly coated on a silica gel material, so that the viscosity is poor and can only keep 1 month of viscosity.
Therefore, the self-adhesive silica gel bra mold cups prepared in the embodiments 1 and 2 have high hardness and good shaping effect, are not easy to deform in the stretching process, can better fit the skin, and can maintain better gathering effect of the chest; combine intermediate junction layer, further make the self-adhesive silica gel brassiere mold cup edge that the preparation obtained hard, difficult limit that sticks up, can not lead to the problem of droing.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
