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
The present invention relates to the composition of macromolecular compound, specifically, relating to a kind of is the bra liner material and preparation method thereof of base-material with the thermoplastic elastomer.
Background technology
Brassiere is the fashionable dress of chest, is used for protecting women's health, and makes the chest lines graceful more.Existing with the brassiere of moulding sponge as liner, after dressing, the women can increase its graceful bearing to a certain extent.But, this is that the brassiere of liner exists many deficiencies with the sponge, mainly show: the foam mat ventilation property is poor, have feeling of oppression and heat or cause the skin discomfort after dressing this brassiere, this situation is even more serious in summer, punching is to strengthen ventilation property on foam mat though some are also arranged, and the foam mat easy deformation after the punching is damaged; Because sponge elasticity is relatively poor, easy deformation is damaged, and therefore this brassiere can not be rubbed and wash, and this has influenced the sanitation and hygiene of brassiere; After the washing, contain in the foam mat, be difficult for drying than juicy; Sponge is easily aging, after this brassiere is changed clothes several times, foam mat aged problem can occur.
Summary of the invention
For remedying the deficiencies in the prior art, a kind of material that is suitable for making bra liner more is provided, it is the bra liner material and preparation method thereof of base-material with the thermoplastic elastomer that the present invention proposes a kind of, its technical scheme is as follows:
Each component and the content thereof of this bra liner material are:
Thermoplastic elastomer;
Weight is 5～10% talcum powder, lime carbonate or zinc oxide of above-mentioned thermoplastic elastomer;
Weight is that 12～25% oil of above-mentioned thermoplastic elastomer is a softening agent;
Weight is 1～3% ketoamine class anti-aging agent of above-mentioned thermoplastic elastomer.
Above-mentioned thermoplastic elastomer can be polyurethanes thermoplastic elastomer (thermoplastic elastomer TPE), thermoplastic natural rubber, melt processible thermoplastic elastomer or silicon rubber.
Above-mentioned talcum powder, lime carbonate or zinc oxide are as weighting agent.Weighting agent has reinforcement and increment dual-use function, is divided into by function: strengthening agent, and it is a main purpose with physical and mechanical propertiess such as the tensile strength that improves described thermoplastic elastomer, tear strength, stress at definite elongation, wear resistance, hardness; Extender, it is to increase the volume or weight of thermoplastic elastomer, and reducing cost is main purpose.Talcum powder can be used as strengthening agent or extender with the grade difference, and the talcum powder price is lower.Lime carbonate comprises water-ground limestone, light calcium carbonate and treated carbonates, price is suitable and can fill in a large number, its strengthening action and its particle diameter, structure, surface properties are relevant, and water-ground limestone and light calcium carbonate are mainly as extender, and treated carbonates is as strengthening agent.Zinc oxide also has the function of vulcanizing agent, promoting agent and tinting material concurrently when being used as weighting agent, have certain reinforcing property, and can improve the stickiness of thermoplastic elastomer, strengthens the thermoplastic elastomer thermal conductivity.When selecting for use, can select suitable weighting agent and consumption thereof, the performance of thermoplastic elastomer is met the requirements according to the purpose that will reach.
Above-mentioned oil is that softening agent can be paraffin oils, naphthenic oil or fragrant hydrocarbon ils.Paraffin oils is paraffin oil again, and fragrant hydrocarbon ils is aromatic hydrocarbon oil or No. 4 rubber oil again, after paraffin oils, naphthenic oil and aromatic hydrocarbon wet goods softening agent enter in the thermoplastic elastomer, has increased the flexibility of thermoplastic elastomer; Increase plasticity-, be convenient to processing; Other Synergist S-421 95 (as weighting agent) there is humidification, makes it to be easy to disperse, shorten mixing time, improve melting efficiency; Increase the flowability, tackyness of thermoplastic elastomer and, be convenient to moulding from stickiness; Increase the winter hardiness of thermoplastic elastomer.In paraffin oils, naphthenic oil and the fragrant hydrocarbon ils, the consistency of paraffin oils and thermoplastic elastomer is relatively poor, and processing characteristics is relatively poor; The consistency of fragrance hydrocarbon ils and thermoplastic elastomer is good, good processability; The consistency of naphthenic oil and thermoplastic elastomer and processing characteristics are all between paraffin oils and fragrant hydrocarbon ils.This plasticizer consumption is many more, and it is soft more that thermoplastic elastomer becomes.When selecting for use, answer bonded products to require to select suitable manufacturing methods and definite its consumption.
The preferred anti-aging agent RD of above-mentioned ketoamine class anti-aging agent, antioxidant A W or antioxidant BLE.These three kinds of ketoamine class anti-aging agent can both protect deterioration by oxidation, thermal ageing and Weather effectively.In addition, anti-aging agent RD has stronger restraining effect to metal catalytic oxidation, and the protective effect hold-time is long; Antioxidant A W energy ozone ageing and flex crack; Antioxidant BLE can protect ozone ageing and flexing fatigue.
The preparation method of this bra liner material may further comprise the steps:
Step 1: with powdery or granulous thermoplastic elastomer and weight is that 5～10% talcum powder of above-mentioned thermoplastic elastomer or lime carbonate or zinc oxide add in the container and kneads, and the time is 4～6 minutes, makes these two kinds of mixing of materials even;
Step 2: 12～25% the oil that adds weight and be above-mentioned thermoplastic elastomer is a softening agent, and it is even to each mixing of materials to knead, and making oil is that softening agent infiltrates in the thermoplastic elastomer;
Step 3: add weight and be 1～3% ketoamine class anti-aging agent of above-mentioned thermoplastic elastomer, make each mixing of materials even;
Step 4:, extrude then and, promptly make the granulous bra liner material in head pelletizing moulding by the forcing machine thermoplastication.
Forcing machine can adopt single screw extrusion machine, and the feed section temperature of its screw rod is 165～180 ℃, and the compression section temperature of screw rod is 180 ℃～200 ℃, and the melt zone temperature of screw rod is 185 ℃～205 ℃.The temperature of screw rod feed section, compression section and melt zone increases successively.
The present invention is base-material with the thermoplastic elastomer, after adding an amount of weighting agent, softening agent, anti-aging agent successively and mixing, again through thermoplastication, the material that obtains has snappiness, thermoplasticity, good anti ageing property and higher flexibility (its shore hardness can hang down and reach-0025 degree).Make bra liner with this material, can a plurality of breather holes be set easily by Shooting Technique on liner, improve the permeability of liner, because this material has snappiness, so the setting of breather hole can not cause the yielding damage of liner; With the soft and high resilience of bra liner that this material is made, comfortable especially when brassiere is worn; Because this material has good anti ageing property, therefore adopt the brassiere long service life of the liner of making by this material; Because the bra liner made from this material is soft and high resilience, so brassiere cleans conveniently, can be at will rubs with hand and washes or washing machine cleaning and can not cause the deformed damaged of liner, and the brassiere water content after the cleaning is few, dries easily; This material does not contain harmful material, and is safe in utilization; The bra liner thermal adaptation scope made from this material is big, is-50 ℃～80 ℃.
