Problems solved by technology

In the prior art, most of the pads are some plastic foam materials, which have the disadvantages of being difficult to wash, easy to age, and difficult to dry after washing; Adding chemical foaming agents and foaming aids, some people are prone to allergic reactions when exposed to such substances
In recent years, there has also been a type of silicone rubber bra pad made of silicone rubber, but because this type of silicone rubber bra pad is a product that has not been hydrogenated and saturated during the manufacturing process, it has poor anti-oxidation and anti-allergic properties and heavy odor.

Add 0.5 parts of alkyl polyphenol antioxidant 1010, 0.5 part of phosphite antioxidant 168, 1 part of polyethylene wax, and 50 parts of talc powder (1250 mesh) to the oil-extended SEBS elastomer, at high speed Blend for 15 minutes;

[0022] 2) Pelletizing: Put the uniformly mixed material into a twin-screw extruder to extrude and granulate. The process conditions for granulation are 150-155°C in the feeding section, 165-170°C in the melting and compression section, and 165-170°C in the homogenizing section. 170-175°C, the die temperature is 170°C, the screw speed is 250-350 rpm;

[0023] 3) Injection: Add the prepared pellets to the injection machine for injection moldi...

Embodiment 2

[0027] 1) Mixing material: Add 100 parts of powdered low molecular weight (about 70,000) SEBS elastomer into a high-speed mixer and stir for 5 minutes, then add 100 parts of naphthenic rubber oil and 100 parts of paraffin base rubber oil, and then stirred for 20 minutes to obtain an oil-extended SEBS elastomer. 15 parts of EVA resin, 0.5 part of maleic anhydride grafted SEBS, 0.5 part of alkyl polyphenol antioxidant 1010, 0.5 part of alkyl polyphenol antioxidant DLTP, 1 part of zinc stearate, 35 parts of talcum powder (1250 mesh) added to the oil-extended SEBS elastomer, and stirred for 15 minutes in a high-speed mixer;

[0028] 2) Pelletizing: Put the uniformly mixed material into a twin-screw extruder to extrude and granulate. The process conditions for granulation are 150-155°C in the feeding section, 170-175°C in the melting and compression section, and 170-175°C in the homogenizing section. 175-180°C, the die temperature is 175°C, the screw speed is 250-350 rpm;

Abstract

The invention relates to a bra backing material and a preparation method of the bra lining material. The preparation method comprises the steps of: 1) adding a powder-shaped styrene-ethylene-butadiene-styrene (SEBS) thermoplastic elastomer into a high-speed mixing machine, stirring, adding mineral oil with regulated parts and stirring again to obtain an oil-charging type SEBS elastomer; 2) adding antioxygen, lubricating agents, coloring agents and filling agents into the oil-charging type SEBS elastomer obtained in the step 1), uniformly stirring the mixture in the high-speed mixing machine and adding an ethylene-vinyl acetate copolymer and a compatilizer to be mixed; 3) extruding and pelletizing the mixture obtained in the step 2) in a double-screw extruder. The bra lining material has the beneficial effects that the lining material has the characteristics of anti-aging, low cost, low hardness, high elasticity, high flexibility and comfortable handfeel, and is difficult to soak and convenient to clean; through an injection process, the bra liner is conveniently and directly molded; moreover, pouring materials can be recycled, so that the liner is simple in process, low in energy consumption, high in efficiency, high in repeatability and easy to operate.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a bra pad material and a preparation method thereof, in particular to a SEBS thermoplastic elastomer bra pad material, a preparation method and use thereof. Background technique [0002] Bras can modify and protect women's breast deformities, and can make women's breast lines more beautiful. Bras generally require padding to be added to the cups during use. In the prior art, most of the pads are some plastic foam materials, which have the disadvantages of being difficult to wash, easy to age, and difficult to dry after washing; Adding chemical foaming agents and foaming aids, some people are prone to allergic reactions when exposed to such substances. In recent years, there has also been a type of silicone rubber bra pad made of silicone rubber, but because this type of silicone rubber bra pad is a product that has not been hydrogenated and saturated during t...
