Problems solved by technology

[0004] At present, the drawing glue resins on the market mainly achieve the effect of elastic drawing by adding other gel substances to the colloid. However, the viscoelasticity and appearance drawing effect of the above drawing glue resins are not good, and the storage stability is poor. Easy to gel

preparation example Construction

[0040] The present invention also provides a method for preparing the elastic drawing photocurable resin described in the above technical solution, comprising the following steps:

[0041] a) under the action of a catalyst, the isocyanate and the polyol react to form a prepolymer of isocyanate;

[0042]b) Under the action of a catalyst, the isocyanate-terminated prepolymer reacts with the hydroxyl acrylic acid monomer to form a double bond-containing prepolymer with a part of the isocyanate reserved;

[0043] c) Mixing and reacting the double-bond-containing prepolymer with reserved part of isocyanate, amine active material and molecular weight modifier to obtain elastic drawing photocurable resin.

[0044] Wherein, the type and amount of the isocyanate, polyol, hydroxyacrylic acid monomer, amine active substance, molecular weight regulator and catalyst are consistent with those described in the above technical solution, and will not be repeated here.

[0045] Regarding step ...

Embodiment 1

[0067] Example 1: Preparation of Elastic Drawing Photocurable Resin

[0068] 1. Raw materials:

[0069]

[0070] 2. Preparation:

[0071] S1. Put isophorone diisocyanate and catalyst T-12 (0.2 parts) into the reaction flask, heat up to 60°C, and add polyether polyol N210 (M n =1000), and reacted at 60°C for 2 hours to obtain a prepolymer with terminal isocyanate.

[0072] S2. Infuse air, add hydroxyethyl acrylate and catalyst T-12 (0.1 part) dropwise to the obtained isocyanate-terminated prepolymer, and react at 80° C. for 3 hours to obtain a double bond-containing prepolymer with reserved part of isocyanate, Its NCO content = 2.69%.

[0073] S3. Cool down to 40°C the temperature of the double bond-containing prepolymer obtained in step S2 with reserved part of the isocyanate, add isophorone diamine and molecular weight regulator HC5320, and react at 40°C for 2 hours to obtain an elastic drawing photocurable resin.

Embodiment 2

[0074] Example 2: Preparation of Elastic Drawing Photocurable Resin

[0075] Implementation according to Example 1, the difference is that the isophorone diisocyanate in step S1 is replaced by dicyclohexylmethane diisocyanate (H 12 MDI), the polyether polyol was replaced by polyester polyol XCP-355 of equal quality (Asahikawa Chemical).

Abstract

The invention provides an elastic wire-drawing light-cured resin and a preparation method thereof, and an elastic wire-drawing adhesive. The elastic wiredrawing light-cured resin provided by the invention is prepared from the following raw materials in parts by mass: 25-35 parts of isocyanate, 55-65 parts of polyol, 10-15 parts of a hydroxy acrylic monomer, 1-2 parts of an amine active substance, 0.5-1 part of a molecular weight regulator and 0.1-1 part of a catalyst. The raw materials are matched according to a certain proportion, so that the obtained elastic wiredrawing light-cured resin has higher curing speed and good yellowing resistance, flexibility and wiredrawing effect.

Description

technical field [0001] The invention relates to the field of nail art materials, in particular to an elastic drawing photocurable resin, a preparation method thereof, and an elastic drawing glue. Background technique [0002] Nail polish drawing glue is a kind of product used in the nail art industry. It is a drawing thread glue that is easy to modify and modify. The colloid is relatively viscous, and when you pick it out, you can see a line. It is elastic and not easy to break. You can complete the outline of a very thin line with one stroke. The main component of nail polish glue is elastic glue resin, which can be used in nail polish glue, and can also be used to draw patterns and draw lines in nail art. [0003] According to the use requirements of nail polish drawing glue, the elastic drawing glue resin is required to have fast curing speed, good toughness, yellowing resistance, high viscoelasticity, and a brushed appearance. The resin can be picked up with a toothpick...
