Problems solved by technology

This process has obvious defects. First, in order to ensure the extension of the nail strength, the glue contains mostly high-functional resins. Due to the thick application, the heat release is large, which will cause damage to the nails. Second, the operation is cumbersome and requires 2-3 times of repeated application and exposure. , takes a long time; third, high-functional resins often cause curing shrinkage, causing stress on the nails, and there will be discomfort
[0003] In the case that health, efficiency and comfort have become the mainstream of beauty makeup, this kind of extended nail polish can no longer meet the needs of nail art.
Aiming at the defects of the existing extension nail polish, the present invention provides a new extension glue and its application process

preparation example Construction

[0063] The preparation method of nail extension glue of the present invention includes the following steps:

[0064] (1) Add acrylate oligomer, reactive diluent, photoinitiator, and defoamer into a stirring vessel in a fixed proportion, and stir at 500-1000 revolutions / min for 30-60 minutes. The test temperature during stirring is not higher than 70 degrees Celsius.

[0065] (2) Add a certain proportion of acrylic powder to the mixture prepared in the first step, stir for 30-60 minutes at a speed of 500-1000 revolutions / min, while vacuuming to remove air bubbles, the test temperature is not higher than when stirring and deaeration 70 degrees Celsius.

[0066] The method of using the nail extension glue of the present invention includes the following steps:

[0067] S1) Take an appropriate amount of nail extension gel and put it in the release nail piece, dip a small amount of alcohol with a brush, and press the extension gel to cover the inner wall of the release nail to form the tar...

Embodiment 1

[0077] The acrylate oligomer is a trifunctional polyurethane acrylate, its number average molecular weight is 2000D, the reactive diluent is isobornyl acrylate, hydroxyethyl methacrylate, the mixing ratio is 1:2, and the initiator is diphenyl -(2,4,6-Trimethylbenzoyl)phosphorus oxychloride, 1-hydroxycyclohexyl phenyl ketone mixture, the mixing ratio is 1:1, PMMA microspheres have an average particle size of 20um, and the defoamer is BYK -065.

[0078] The preparation method of Example 1 is

[0079] 1. Add acrylate oligomer, reactive diluent, photoinitiator, and defoamer into a stirring vessel in a fixed proportion, and stir at 1000 rpm for 40 minutes. The test temperature during stirring is not higher than 70 degrees Celsius.

[0080] 2. Add acrylic powder to the mixture prepared in the first step in proportion, stir at 800 rpm for 30 minutes, while vacuuming to remove air bubbles, the test temperature is not higher than 70 degrees Celsius during stirring and deaeration, and cooling...

Embodiment 2

[0082] The acrylate oligomer is a four-functional polyurethane acrylate with a number average molecular weight of 2500D. The reactive diluent is trimethylolpropane triacrylate and hydroxyethyl methacrylate. The mixing ratio is 1:1. The initiator It is a mixture of 2-methyl-1-[4-(methylthio)phenyl]-2-(4-morpholinyl)-1-propanone and 1-hydroxycyclohexylphenyl ketone, the mixing ratio is 1 :3, PMMA microspheres have an average particle size of 30um, and the defoamer is Airex 920.

[0083] The preparation method of Example 2 is similar to that of Example 1, and the usage method is also similar.

Abstract

The invention provides a nail lengthening adhesive; the nail lengthening adhesive is characterized by comprising the following components by the mass percentage: 40-75% of an acrylate oligomer, 5-15%of an active diluent, 2-5% of a photoinitiator, 15-40% of acrylic micro-powder, and 0.01-2% of a defoamer. The nail lengthening adhesive has the advantages of high strength and toughness. The acrylicpowder contained in the colloid, as a reinforcement body, has a reinforcing effect on a cured adhesive, improves the hardness and tensile strength, and makes the lengthening adhesive not easy to breakand wear in daily life.

Description

Technical field [0001] This application relates to the technical field of nail art, and in particular to a nail extender and its preparation method and application. Background technique [0002] At present, the popular extension nails on the market mostly use the paper support technique, that is, put the paper nails on the fingers and apply the extension nail polish to the nails and the paper support. Each time you apply nail polish extender for about 200-300um, after 30-60 seconds of UV exposure, repeat the application 2-3 times. The defects of this process are obvious. First, to ensure the extension of nail strength, the glue contains high-functional resin. Due to the large thickness of the application, the heat release is large, causing damage to the nails; second, the operation is cumbersome, requiring 2-3 repeated application and exposure , It takes a long time; third, high-functional resins often cause curing shrinkage, causing stress to the nails, and discomfort. [0003] ...
