Abstract
The invention belongs to the technical field of UV (ultraviolet) curing materials, and particularly relates to an epoxidized soybean oil-based acrylic ester-polyurethane UV (ultraviolet) curing resin and a plant oil-based nail polish gel prepared from the same and containing no TPO (thermoplastic olefin) photoinitiator. Firstly, reacting epoxidized soybean oil and acrylic ester at 100-130 ℃, cooling to 50-80 ℃ after the acid value is unchanged, and adding diisocyanate to continue the reaction to obtain prepolymer; and then, respectively carrying out esterification reaction on the two anhydride curing agents and hydroxyl acrylate, and introducing the two anhydride curing agents into a prepolymer for crosslinking reaction to finally obtain the epoxidized soybean oil-based acrylic ester-polyurethane UV light-cured resin. And uniformly mixing the obtained resin with TMO photoinitiator, amine modified resin, castor oil resin, active monomer, auxiliary agent and color paste to obtain the vegetable oil-based nail polish gel without TPO photoinitiator. The resin and the nail polish gel have high biological base content, and the obtained coating has better mechanical property.
Description
Technical Field
The invention belongs to the technical field of UV (ultraviolet) curing materials, and particularly relates to an epoxidized soybean oil-based acrylic ester-polyurethane UV (ultraviolet) curing resin and a plant oil-based nail polish gel prepared from the same and containing no TPO (thermoplastic olefin) photoinitiator.
Background
Nail polish is one of a plurality of cosmetics, is generally used for hand/foot nails, has rich and varied colors and styles, has attractive and decorative effects, is deeply touted and loved by a plurality of women, and however, common nail polish contains substances harmful to human bodies. With the rise of UV curing technology, UV nail polish is a popular nail polish product in recent years, which is in the public view. The UV nail polish generally adopts a traditional UV lamp or an LED lamp for curing, and compared with the common nail polish, the UV nail polish has the advantages of environmental protection, no toxicity, high curing rate, longer maintenance time and the like, so that the nail polish gradually replaces the common nail polish.
The main components of the UV nail polish comprise main resin, a photoinitiator, an auxiliary agent and color paste, wherein the main component is the main resin. At present, the petroleum-based material is taken as main resin of the nail polish with a relatively large occupation ratio, but the petroleum-based material is non-renewable and is easy to cause environmental pollution. Therefore, a need exists for a low cost, environmentally friendly, renewable biomass resource based resin for the preparation of nail polish.
Photoinitiators are an important component of UV nail polish, and are indispensable, although the proportion of the formulation is generally not high. Although the initiator is various at present, many photoinitiators have the problems of containing harmful substances, low initiation efficiency, poor compatibility and the like. For example, the photoinitiator TPO is a photoinitiator commonly used in nail polish, however the European photo-curable coating ink industry has classified the photoinitiator TPO as a reproductive toxicity 2 in CLP (Classification, labeling and packaging) regulations, and the photoinitiator TPO is likely to be reclassified by the European Union as a reproductive toxicity 1B species in CMR, if such a classified change becomes realistic, meaning that the photoinitiator TPO will be disabled or restricted in many applications. Therefore, another photoinitiator which is suitable for nail polish and has good safety, high efficiency and good compatibility is needed to be searched, and the nail polish with good adhesive force, good wear resistance and good toughness is prepared.

In the step (1), the reaction can be stopped after the acid value is measured once in the reaction process of the acrylic ester and the epoxidized soybean oil, and the reaction time does not need to be strictly controlled; the reaction product of acrylic ester and epoxidized soybean oil has low viscosity (4000-8000 mPa.s), no gel phenomenon and better thermal stability. After the reaction is finished, the temperature is reduced to 50-80 ℃ to add diisocyanate for reaction, the temperature is not required to be reduced to room temperature, and the control of the temperature is not strict; the acrylate and the epoxidized soybean oil are subjected to ring-opening reaction to generate hydroxyl, and diisocyanate is directly added into the hydroxyl to prepare the prepolymer through a one-pot method, so that the preparation process is simple.

Carbon-carbon double bonds and ester groups can be formed in the process of ring-opening reaction of the epoxidized soybean oil and acrylic ester, and the active groups can promote the quick solidification of the UV nail polish; and then hydroxyl and diisocyanate generated after the ring-opening reaction of the epoxidized soybean oil and the acrylic ester form amide bonds again, so that the hardness and toughness of the resin are improved, and the general performance requirements of the nail polish gel are met; in addition, the addition of the anhydride curing agent can promote the resin to be fully crosslinked, so that the raw materials are uniform and compatible, and better compatibility with TMO photoinitiator and components of the nail polish gel is realized.
In the process of preparing the resin, the special groups such as hydroxyl, double bond, ester group and the like are reacted, and the anhydride derivative and the prepolymer are subjected to crosslinking and compounding to participate in photo-curing, so that the viscosity of the resin can be greatly reduced, and the toughness, hardness and stability of a resin cured film are improved.
