Description

Adhesive composition for hair extension, hair extension method and hair piece

The present invention relates to an adhesive, in particular to an adhesive composition for hair extension, a hair extension method using the adhesive composition, and a hair piece for hair extension.

Love beauty is human nature, so there are many beauty salons in the shop. In particular, hairdressers are all upgrading their technology so that customers can change their face or have a new feeling and surprise. In recent years, the popular hair extensions have made women who love beauty love it. As a result, professional hairdressing technicians continued to develop or introduce various hair extension technologies.

Known hair extension technologies include clip-on hair extensions, patch hair extensions, hot-press hair extensions, braided hair extensions, and crystal wire hair extensions. However, the aforementioned methods of receiving and sending still have their problems.

Among them, the clip-on hair extensions are like the new type M538713 "Quick hair extension supplies and their structure" of the country, which exposes a wig, which has a compressible deformable body for clamping a pinch of real hair, and the compressible deformable body has a Providing a penetrating portion for clamping the pinch of real hair after passing through the pinch of real hair, and most of the wigs combined with the compressible deformable body; and a pre-worn in the penetrating portion for guiding the pinch of real hair through Trap in the bodice. In this way, a pinch of real hair can be passed through the snare, and then the snare can be pulled away from the wearing part, and at the same time, the snippet can guide the pinched real hair through the wearing part, and then use an adhesive to stick the pinched real hair and compress the deformation Body, and pressurize and compress the deformable body to clamp the pinched hair, and then complete the quick hair extension structure. However, if the compression-deformed body is caught in the hair, it will cause an uncomfortable feeling of foreign body.

Patch-type hair extensions such as the national new "M547288" "adhesive hair piece", which exposes a hair piece with a wig, a hair piece that fixes one end of the wig, and a double-sided tape with an adhesive tape The first side of the adhesive tape is pre-adhered to the side of the bundle and the wig, and the second side of the adhesive tape is covered with a peelable release paper. It uses yellow glue, white glue or blue glue and other materials. The colloid itself will melt due to contact with heat. For example, after washing hair with warm water, it will cause residual glue, which will cause abnormal hair pull-out problems and insufficient adhesion. Therefore, it must be A large piece of tape is used to increase the bonding area to improve the adhesion, but it cannot be used on a small amount of hair, thus reducing the freedom of styling or causing unnatural styling.

The splicing hair piece requires skilled implementation technology, and the time required for styling is also very long, so the cost is relatively expensive, and consumer acceptance is not high.

Crystal wire hair extension is made with crystal wire. The winding of the wire body takes a long time, and requires a skilled technician to operate. This method will be easy to detach, inconvenient to comb and easy to find the contact. problem.

The hot press type hair extension is like the new national patent cases of M547312 "Quick Hair Extension Structure" and M545476 "Hot Press Hair Extension Apparatus and Hair Extension Structure" patent cases. Case No. M547312 discloses a wig with a thermoplastic unit for clamping a pinch of real hair. The thermoplastic unit has a piercing part for clamping the pinch of real hair after passing through the pinch of real hair. And most of the wigs combined with the thermoplastic unit; and a snare that is pre-pierced in the piercing part to guide the pinch of real hair through the piercing part. In this way, a pinch of real hair can be passed through the snare, and then the snare can be pulled away from the piercing part, and at the same time, the snippet can guide the pinch of the real hair through the piercing part, and then use a hot pressing tool to clamp the thermoplastic unit to cause the clip Tighten the hair, then complete the hair extension. The case No. M545476 discloses a hot-melt part and a wig connected to the hot-melt part. The hot-melt part has at least three fins arranged radially and formed between the three fins Three accommodating recesses into which multiple hair bundles are placed; thereby, a heating clip is used to apply pressure and heat to the hot-melt member to melt the fins of the hot-melt member to cover the hair in the accommodating recesses, thereby forming heat Crimp hair structure. In addition, some manufacturers use copper rings or aluminum rings to clamp the real hair and the hair piece together. Either way, it is necessary to use a clamp or a hot clamp to clamp forcefully, which is laborious and time-consuming, and it is easy to cause the problem of falling off easily after washing the hair.

Therefore, how to provide a receiving and sending technology that solves one of the above-mentioned problems is really an issue that the related industry urgently wants to overcome.

In view of the above-mentioned problems, one object of the present invention is to provide an adhesive composition for hair extensions, which can improve the adhesive strength, does not have a sol after shampooing with warm water, and has the effect of easily removing glue without leaving a residue.

Therefore, the adhesive composition for hair extension of the present invention comprises an aliphatic urethane acrylate oligomer whose content is 50 to 65% by weight, and an aliphatic polyester acrylate oligomer whose content is 20 to 35 weight %, and Yiguang initiator, its content is 5~15% by weight.

In one embodiment, the content of the aliphatic urethane acrylate oligomer ranges from 60 to 65% by weight.

In one embodiment, the content of the aliphatic polyester acrylate oligomer ranges from 28 to 33% by weight.

In one embodiment, the content of the photoinitiator is between 5 and 15% by weight.

In one embodiment, the content of the photoinitiator is between 4 and 6% by weight.

In one embodiment, it further contains a fragrance with a content of 2-6% by weight.

In one embodiment, it further contains a fragrance with a content of 2 to 4% by weight.

In one embodiment, it further includes a colorant with a content of 1 to 5% by weight.

In one embodiment, it further comprises a colorant with a content of 1 to 2% by weight.

In addition, another object of the present invention is to provide a hair extension method to improve the adhesive strength and save time and operation convenience.

Therefore, the hair extension method of the present invention includes providing the aforementioned adhesive composition, and providing a hair extension to be received, the hair extension to be received includes a carrier and a hair bundle connected and fixed to the carrier by one end, and a Point the adhesive composition on the surface, then adhere the surface of the carrier containing the adhesive composition to a human hair, and then use an ultraviolet lamp to irradiate the adhesive composition to cure the adhesive composition .

In one embodiment, the carrier is perforated before the adhesive composition is spotted on a surface of the carrier.

Furthermore, another object of the present invention is to provide a hair piece to improve the adhesive strength.

Therefore, the hair piece of the present invention includes a carrier and a hair tress. The carrier includes two opposite surfaces, one end of the hair bundle is sandwiched between the surfaces, and includes at least one hole penetrating the surfaces.

As described above, the effect of the adhesive composition for hair extensions and the hair extension method of the present invention is that it contains an appropriate amount of aliphatic urethane acrylate oligomer and aliphatic polyester acrylate oligomer, thereby improving the hair extension The adhesive strength and the light-cured adhesive exhibit suitable softness and hardness, are not easy to leave glue, are easy to remove glue, and have the effect of saving time and effort in operation.

A hair extension adhesive composition according to a preferred embodiment of the present invention includes an aliphatic urethane acrylate oligomer, an aliphatic polyester acrylate oligomer, and a photoinitiator. In detail, the content of the aliphatic urethane acrylate oligomer (Aliphatic Urethane Acrylate Oligomer) is between 50 and 65% by weight (wt%). The content of the aliphatic polyester acrylate oligomer (Aliphatic Polyester Acrylate Oligomer) The content is between 20 and 35% by weight (wt%), and the content of the photoinitiator is between 5 and 15% by weight (wt%).

The production process is to put aliphatic urethane acrylate oligomer (Aliphatic Urethane Acrylate Oligomer), aliphatic polyester acrylate oligomer Aliphatic Polyester Acrylate Oligomer) and photoinitiator (Photoinitiator) into a container and heat to 60-C Stir well at 70 degrees.

In another feasible embodiment, the content of the aliphatic urethane acrylate oligomer (Aliphatic Urethane Acrylate Oligomer) is between 60 and 65% by weight, and the content of the aliphatic polyester acrylate oligomer (Aliphatic Polyester Acrylate Oligomer) It is between 28 and 33% by weight, and the content of the photoinitiator is between 4 and 6% by weight.

It is worth mentioning that when the content of the aliphatic urethane acrylate oligomer (Aliphatic Urethane Acrylate Oligomer) is higher than 65% by weight, the adhesion will be too strong, which will make it difficult to remove the glue; on the contrary, when the aliphatic polyurethane If the content of the acrylate oligomer (Aliphatic Urethane Acrylate Oligomer) is less than 50% by weight, it will result in insufficient adhesion, and the hair extension piece 1 is easy to detach from the hair on the head.

However, when considering the adhesive strength factor, the softness and hardness of the adhesive (or colloid) after light curing must also be considered. Therefore, the test results found that when the content of the aliphatic polyester acrylate oligomer (Aliphatic Polyester Acrylate Oligomer) is higher than 35% by weight, the colloid after photocuring is too hard, and there will be discomfort (or obvious foreign objects) Sense); conversely, when the content of the aliphatic polyester acrylate oligomer (Aliphatic Polyester Acrylate Oligomer) is less than 20% by weight, the light-cured colloid is too soft, and there will be tangles with the hair of other parts, especially When wearing a hard hat or leaning your head on a chair or pillow.

The photoinitiator is used to make the adhesive composition undergo a photoinitiation reaction. The photoinitiator can be selected from the following but not limited to: 2,4,6-trimethylbenzoyl diphenyl phosphine oxide (Diphenyl (2,4,6-trimethylbenzoyl)-phosphine oxide, TPO), 2,4,6-trimethylbenzoyl phenylphosphinate Ethyl(2,4,6-trimethylbenzoyl)phenylphosphinate (TPO-L), 2,4,6-trimethylbenzoyl Acetyl diphenyl phosphine oxide or 1-hydroxycyclohexyl phenyl ketone.

In order to meet different styling needs, in a feasible embodiment, add 1 to 5% by weight of color pigment (Colour Pigment), such as black hair, you can add black color pigment, so that after the completion of the hair extension will have an invisible effect; of course For people with different hair colors, in order to have an invisible effect, you can choose the color material corresponding to the hair color; of course, if you want to highlight the special effect, add a color material that is different from the hair color. In another embodiment, the color material may be 1 to 2% by weight, so that a lighter color is formed.

In addition, in order to allow different odors to appear after finishing the hair extension, 2 to 6% by weight of fragrance (Fragrance) can be added. If you need a light smell, you can add 2 to 4% by weight of spices.

The steps of the receiving and sending method of the present invention are described below.

A hair extension piece 1 is provided. The hair extension piece 1 includes a carrier 10 and a hair bundle 12 connected and fixed to the carrier 10 with one end 11, and the adhesive composition is formed on a surface 101 of the carrier 10.

Next, the surface 101 of the carrier 10 is adhered to an appropriate amount of hair (not shown) of the human body. The carrier 10 may be located above or below the hair.

Next, the adhesive composition is irradiated with a photo-curing lamp (not shown) such as an ultraviolet lamp for about 1 to 3 seconds, and then the adhesive composition is irradiated and cured. Among them, the wavelength emitted by the ultraviolet lamp is between 320nm and 400nm, and the light is illuminated by it.

It is worth mentioning that, in order to further improve the fixing effect of the human hair and the hair piece 1 to be received, the carrier 10 can be punched with a hole 100 penetrating through both surfaces 101 of the carrier 10, so that the adhesive composition at subsequent points can be Flowing into the hole 100 to form a cured adhesive has the effect of being embedded in the hole. It must be noted that there may be multiple holes 100. The carrier 10 may be, for example, a non-woven fabric sandwiching the hair tress 12 in two layers.

In order to attract the attention of outsiders, the carrier can be trimmed into a specific pattern or an adhesive composition on the dots, and then a decorative object (such as a crystal drill) can be adhered through the adhesive on the carrier 10, and then irradiated with a curing lamp , The irradiation time is longer than the time when no ornament is generally used.
