Foamed silica gel material for bra and preparation method thereof

Abstract

The invention provides a foamed silica gel material for a bra. The foamed silica gel material specifically comprises the following raw materials in percentage by weight: 65 to 80% of raw rubber, 4.5 to 11% of a plasticizer, 0.01 to 1.15% of a structure control agent, 8 to 15% of silicon dioxide, 0.01 to 0.4% of a catalyst and 0.5 to 1.5% of 2,5-dimethyl-2,5-bis-(tert-butylperoxy) hexane, 4.5-8% ofa foaming agent, 0.1-2.0% of a boron-containing compound or borate, 0.1-1.5% of a cross-linking agent, and 0.1-1.5% of an anti-aging agent. The invention further provides a preparation method of thefoamed silica gel material for the bra. The foaming silica gel material is obtained by adding the plasticizer, the cross-linking agent, the anti-aging agent and other components into raw rubber, the foaming silica gel material obtain by allowing proper weight percentage of components to enter a mold machine table and fully foaming at a certain temperature has good mechanical properties and thermalproperties.

Description

Technical field [0001] The invention belongs to the field of foamed materials, and particularly relates to a foamed silicone material for bras and a preparation method thereof. Background technique [0002] Foamed silica gel is a material with many good properties such as shock absorption, sound insulation, heat insulation, sealing, air permeability, and non-toxicity. It has been widely used as a filling material in many industries, and it is also widely used in common living areas. Applications, such as the filling material of women’s underwear, as a personal material that needs to be worn for a long time. When some conventional molded sponges are used as lining materials, there are many shortcomings and shortcomings. The main reason is that the air permeability of the sponge is limited. Long-term wearing will produce a sense of stuffiness or cause Skin discomfort, allergies and skin diseases can occur in severe cases. These conditions are particularly prominent in summer. Altho...

[0002] Foamed silica gel is a material with many good properties such as shock absorption, sound insulation, heat insulation, sealing, breathability, and non-toxicity. It has been widely used as a filling material in many industries, and it is also widely used in common life fields. Applications, such as filling materials for women's underwear, as close-fitting materials that need to be worn for a long time, when some conventional shaped sponges are used as lining materials, there are many deficiencies and shortcomings, mainly because the air permeability of the sponge is limited, and long-term wearing will cause stuffy feeling or cause Skin discomfort, allergies and skin diseases can occur in severe cases. These conditions are especially prominent in summer. Although the sponge has also been improved in this regard, such as perforating to increase air permeability or increase or decrease in thickness, due to the inherent properties of the sponge, the elasticity is poor. The deformation is small, easy to age, and the sponge is easy to deform and become thin when the number of times of washing is long, and the internal tissue is easy to form flocs and powders, which causes unsightly appearance and also brings bad personal hygiene problems

At the same time, after the common foaming material is obtained by foaming, it is easy to produce gel after being placed for a long time, and the uniformity of the bubbles after foaming cannot be accurately controlled, and as a close-fitting lining material, good comfort cannot be achieved.
