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 of the 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, they are easily deformed and damaged, 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

[0021] A kind of bra cushion material is prepared successively according to the following procedures:

[0022] Step 1: 1000 grams of granular polyurethane thermoplastic rubber and 50 grams of calcium carbonate were added to the container and kneaded for 4 minutes to mix the two materials evenly;

[0023] Step 2: adding 120 grams of paraffin oil, kneading until all materials are mixed evenly, so that the paraffin oil penetrates into the polyurethane thermoplastic rubber;

[0024] Step 3: Add 30 grams of anti-aging agent RD to mix all materials evenly;

[0025] Step 4: Heat plasticizing through the extruder, then extrude and pelletize at the machine head to form 1200 grams of granular bra pad 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.

Embodiment 3

[0035] A kind of bra cushion material is prepared successively according to the following procedures:

[0036] Step 1: 1000 grams of powdery melt-processable thermoplastic rubber and 100 grams of calcium carbonate were added into the container and kneaded for 6 minutes to mix the two materials evenly;

[0037] Step 2: adding 250 grams of aromatic hydrocarbon oil, kneading until the materials are evenly mixed, so that the aromatic hydrocarbon oil penetrates into the melt-processable thermoplastic rubber;

[0038] Step 3: Add 10 grams of anti-aging agent BLE to mix all materials evenly;

[0039] Step 4: Heat plasticizing through the extruder, then extrude and pelletize at the machine head to form 1360 grams of granular bra pad material. The extruder adopts a single-screw extruder, and the feeding section of the screw The temperature is 170°C, the temperature of the compression section of the screw is 185°C, and the temperature of the melting section of the screw is 190°C.

Abstract

The invention discloses a bra cushioning material by using thermoplastic rubber as the base, which is prepared from thermoplastic rubber, talcum powder, calcium carbonate or zinc oxide, petroleum series plasticizing agent, and amine antioxidants through the steps of mixing, thermal plasticizing, squeezing and granulating.

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 of the 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, they are easily deformed and damaged, so this kind of bra cannot be rubb...
