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 the materials are evenly mixed, 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.

Abstract

A brassiere cushion material with thermoplastic rubber as the base material, consisting of thermoplastic rubber, talcum powder, calcium carbonate or zinc oxide with a weight of 5-10% of the above-mentioned thermoplastic rubber, and petroleum with a weight of 12-25% of the above-mentioned thermoplastic rubber It is composed of a plasticizer and a ketone-amine anti-aging agent whose weight is 1-3% of the above thermoplastic rubber. The preparation method of the bra cushion material is mainly to sequentially add each compounding agent into the thermoplastic rubber and mix the materials uniformly; then heat-plasticize through an extruder, extrude and pelletize at the machine head. The material obtained by the invention has high elasticity, thermoplasticity, good aging resistance and higher softness. Using this material to make bra pads can conveniently set multiple air holes on the pad, which has good air permeability, softness and elasticity, is particularly comfortable to wear, is not easy to be deformed and damaged, has a long service life, is convenient to clean, and is easy to dry .

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...
