Problems solved by technology

[0010] In order to overcome the disadvantages that the existing photocurable materials mainly use abietic acid structural unit as the grafting reactant and fail to fully reflect the structural characteristics of rosin, the invention provides a photocurable material of allyl rosin resinate and a preparation method thereof. Directly use allyl rosin resin as photocurable material prepolymer

preparation example Construction

[0053] The preparation method of the allyl rosin resinate photocurable material comprises the steps of: weighing the raw materials in proportion, adding allyl rosin resinate and a conventional photoinitiator into the diluent or active diluent, stirring evenly to prepare Prepolymer solution, the prepared prepolymer solution is made into a uniform liquid film on the tinplate sheet with a wet film preparation device, and put into a UV light curing machine to cure and form a film. After the curing is completed, the rosin resin acid allyl Ester light curing material. After the curing is completed, diluent or active diluent is used to dissolve the cured film formed on the tinplate sheet, carry out infrared spectrum analysis and characterization, and measure the conversion rate of vinyl double bonds.

[0054] When used in conjunction with conventional photocuring monomers, the steps are: Weigh the raw materials in proportion, add allyl rosin resin, conventional photocuring monomers a...

Embodiment 1

[0065] Allyl rosin resinate 50mg, Darocure 1173 photocuring reaction initiator 2.5mg (equivalent to 5% of the mass of allyl resinate) were dissolved in 1.5mL tetrahydrofuran, and stirred evenly to form a prepolymer solution. Use a 100μm wet film preparation device to evenly coat the prepolymer solution on a tin plate with a specification of 80cm×40cm, and place it in a UV light curing machine for curing reaction. The UV curing conditions are: light distance 4.5cm, UV light intensity 100% means the working power is 600W and the light time is 300s. After curing, the performance of the cured film was measured by dissolving the cured film in tetrahydrofuran, and the results are shown in Table 1 (the same below).

Embodiment 2

[0067] 50 mg of allyl rosin resinate, 4 mg of MK photocuring reaction initiator (8% of the mass of allyl resinate), were dissolved in 1.5 mL of tetrahydrofuran, and stirred evenly to form a prepolymer solution. Use a 100μm wet film preparation device to evenly coat the prepolymer solution on a tin plate with a specification of 80cm×40cm, and place it in a UV light curing machine for curing reaction. The UV curing conditions are: light distance 4.5cm, UV light intensity 100% means the working power is 600W and the light time is 250s. After curing, the properties of the cured film were measured.

Abstract

The invention discloses an abietic resin allyl propionate photo-curing material, which comprises the following components in parts by mass: 1 part of abietic resin allyl propionate, 0.01 to 0.1 part of conventional photoinitiator, 5 to 100 parts of diluent or active diluent, wherein the abietic resin propionate uses colophony as a structure unit and contains vinyl double bonds. When the material is matched with monomer for conventional photo-curing, dosage of the monomer for conventional photo-curing is between 0 and 99 parts, and is not equal to zero. When the abietic resin allyl propionate is applied in photo-curing material prepolymer, the curing time and the surface effect can be controlled by regulating the photo-curing condition. The prepolymer has the characteristic of high curing speed, and the obtained film has good flexibility, impact strength resistance and adhesion, and has high hardness, acid resistance, alkali resistance, salt resistance and water resistance.

Description

technical field [0001] The invention relates to a photocurable material and a preparation method thereof, in particular to a photocurable material using allyl rosin resin as a raw material and a preparation method thereof. Background technique [0002] Rosin is a renewable natural resource. Rosin and its derivatives have been an important component of traditional coatings, inks and adhesives in the past. The amount is large. However, due to the relationship between the composition and chemical properties of traditional rosin and its derivatives, the use of rosin in the emerging field of photocurable materials has been gradually impacted and limited. Therefore, on the basis of maintaining the original advantages of rosin, exploring and developing new ways to use rosin and its derivatives in the field of photocuring reaction has far-reaching positive significance for the deep processing and utilization of rosin and the improvement of the performance of emerging materials. ...
