Antibacterial foamed silica gel artificial breast and preparation process thereof

Abstract

The invention discloses antibacterial foamed silica gel artificial breast and a preparation process thereof. The artificial breast comprises an artificial breast body and reinforcing layers which are bonded to the upper surface and the lower surface of the artificial breast body respectively, wherein the reinforcing layers are hot-melt type high polymer material layers; a raw material formula of the artificial breast body comprises a first component and a second component, a weight ratio of the first component to the second component is 1: 1, the first component comprises silica gel, a foaming agent and an antibacterial agent, and the second component comprises silica gel, a catalyst and an antibacterial agent; and each reinforcing layer is made of one or more selected from polystyrene, polypropylene, an ethylene-vinyl acetate copolymer, a polyethylene-octylene copolymer, a styrene-butadiene-styrene tripolymer and polyurethane. The antibacterial foamed silica gel artificial breast provided by the invention has an efficient antibacterial effect; melt-blown fiber cloth is adhered to the outer surface of the artificial breast body, so the whole artificial breast has very strong tear resistance, and the service life of the artificial breast is prolonged; and the melt-blown fiber cloth and the artificial breast body are well attached, wrinkling is avoided and good hand feeling is achieved.

Description

technical field [0001] The invention relates to the field of prosthetic milk production, in particular to an antibacterial foamed silica gel prosthetic milk and a preparation process thereof. Background technique [0002] Many breast cancer patients need to wear breast prostheses in order to maintain a normal body shape in daily life after mastectomy. Most of the prosthetic breasts currently on the market are prosthetic breasts made of silicone gel material combined with TPU (thermoplastic polyurethane elastomer rubber) film. This type of silicone gel prosthesis has poor air permeability; conventional silicone gel prosthesis has a large proportion and a strong sense of weight when worn; ordinary silicone gel prosthesis has a serious yellowing and aging of the TPU film after being used for a long time, and it is slightly careless when using it It will cause the TPU bag to break and other phenomena; if the TPU film of the ordinary silicone gel prosthetic breast is encountered...

AI Technical Summary

Problems solved by technology

[0003] There are other lightweight prosthetic breasts on the market, but they have many disadvantages, such as cotton bag filled, sponge molded, foamed silicone foam and other types of prosthetic breasts

The first type of prosthesis satisfies the condition of being light and breathable, but its shape is very random, which is insufficient for patients to wear; the second type of prosthesis is perfect in shape, but the sponge contains harmful ingredients, and long-term use will affect health; The third type of prosthetic milk is light in weight and feels good to the touch. However, due to the porous structure of the foamed silica gel, the tear strength is poor, and the gaps between the pores are easy to breed bacteria and mildew, causing health problems.
