Problems solved by technology

But there are many deficiencies in this bra with the sponge as the pad, mainly in: the poor air permeability of the sponge pad, after wearing this bra, there will be stuffy feeling or cause skin discomfort, this situation is more serious in summer, although there are also some Some sponge pads are punched to enhance air permeability, but the punched sponge pads are easily deformed and damaged: due to the poor elasticity of the sponge, it is easy to deform and damage, so this kind of bra cannot be rubbed and washed, which affects the cleanliness of the bra ;After washing, the sponge pad contains more water and is not easy to dry in the sun; the sponge is easy to age, and after this bra is changed and washed several times, the sponge pad will age.

Embodiment 1

[0018] A kind of modified bra liner material is prepared according to the following procedures successively:

[0019] Step 1: 1000 grams of granular polyurethane thermoplastic rubber and 150 grams of calcium carbonate were added to the container and kneaded for 4 minutes to mix the two materials evenly;

[0020] Step 2: adding 300 grams of paraffin oil, kneading until all materials are mixed evenly, so that the paraffin oil penetrates into the polyurethane thermoplastic rubber;

[0021] Step 3: Add 50 grams of anti-aging agent RD to mix all materials evenly;

[0022] Step 4: Heat plasticizing through the extruder, then extrude and cut into pellets at the machine head to form 1500 grams of granular bra cushion material. The extruder adopts a single-screw extruder, and the feeding section of the screw The temperature is 165°C, the temperature of the compression section of the screw is 180°C, and the temperature of the melting section of the screw is 185°C. Each component and c...

Abstract

The invention discloses a bra pad material taking thermoplastic rubber as a base material. The bra pad material is prepared from thermoplastic rubber, talcum powder, calcium carbonate or zinc oxide whose weight is 15-20% of that of the thermoplastic rubber, a petroleum-based plasticizer whose weight is 30-35% of that of the thermoplastic rubber, and a ketoamine-based antioxidant whose weight is 5-8% that of the thermoplastic rubber. The preparation method of the bra pad material mainly comprises the following steps: sequentially adding the compounding agents into the thermoplastic rubber, anduniformly mixing the materials; and then carrying out hot plastication and extrusion by an extruder, and granulating and molding at a machine head. The material provided by the invention has the advantages of high elasticity, thermoplasticity, high anti-aging performance and higher flexibility. When the material is used for manufacturing the bra pad, a plurality of air holes can be conveniently formed in the pad, and the bra pad is good in air permeability, soft, high in elasticity, particularly comfortable to wear, not prone to deformation and damage, long in service life, convenient to cleanand easy to dry in the sun.

Description

technical field [0001] The present invention relates to the composition of macromolecule compound, in particular to a bra cushion material with thermoplastic rubber as base material and its preparation method. Background technique [0002] A bra is a fashion for the chest, which is used to protect women's health and make the chest line more beautiful. Existing brassieres with molded sponges as pads can increase their charm to a certain extent after women wear them. But there are many deficiencies in this bra with the sponge as the pad, mainly in: the poor air permeability of the sponge pad, after wearing this bra, there will be stuffy feeling or cause skin discomfort, this situation is more serious in summer, although there are also some Some sponge pads are punched to enhance air permeability, but the punched sponge pads are easily deformed and damaged: due to the poor elasticity of the sponge, it is easy to deform and damage, so this kind of bra cannot be rubbed and washe...
