Problems solved by technology

At present, most reactive flame retardants are prepared by reacting flame retardant components with epoxy resins to form polyols, which are then prepared into flame retardant polyurethanes or flame retardant polyurethane acrylates for use in coatings. However, these epoxy resins Most of them come from petroleum products and have a great dependence on petroleum resources. Due to the shortage of petroleum resources, most of them will cause certain damage to the ecology, which limits their use in coatings

Embodiment 1

[0043] A preparation method of bio-based multifunctional flame-retardant epoxy acrylate, comprising the steps of:

[0044] (1) In a three-necked flask with a thermometer, add epoxidized soybean oil (24.00g), itaconic acid (3.23g, purity 99%), diethylphosphonoacetic acid (5.08g, purity 95%), triphenyl Phosphine (0.32g) and hydroquinone (0.03g) were stirred with a stirrer at 80°C for 0.5h, and then the temperature was raised to 120°C to continue the reaction for 2h to obtain a phosphorus-containing soybean oil-based epoxy acrylate. The molar ratio between the epoxidized soybean oil, itaconic acid and diethyl phosphonoacetic acid is 1:1:1, and the amount of triphenylphosphine is the total weight of epoxidized soybean oil, itaconic acid and diethyl phosphoacetic acid 1%, the consumption of hydroquinone is 1% of the total weight of itaconic acid.

[0045] (2) In a three-necked flask with a thermometer, add diethylphosphonoacetic acid (20.00g, purity 95%), glycidyl methacrylate (14...

Embodiment 2

[0049] A preparation method of bio-based multifunctional flame-retardant epoxy acrylate, which is the same as Example 1 except for the following steps:

[0050] (4) In a three-necked flask with a thermometer, add itaconic acid (13.00g, purity 99%), glycidyl methacrylate (28.99g, purity 97%), triphenylphosphine (0.42g) and p-phenylene Diphenol (0.42g) was stirred at 80°C for 0.5h with a stirrer, and then the temperature was raised to 90°C to continue the reaction for 2h to obtain an itaconic acid acrylate. The molar ratio between the itaconic acid and the glycidyl methacrylate is 1:2, the amount of triphenylphosphine is 1% of the total weight of itaconic acid and glycidyl methacrylate, hydroquinone The dosage is 1% of the total weight of glycidyl methacrylate and itaconic acid.

[0051] (5) Mix the phosphorus-containing soybean oil-based epoxy acrylate (6.40g) prepared in (1) with the diethylphosphoacetic acid acrylate (1.60g) prepared in (2) to obtain a phosphorus-containing ...

Embodiment 3

[0053] A preparation method of bio-based multifunctional flame retardant epoxy acrylate is the same as Example 2 except the following steps: the mass ratio between the phosphorus-containing soybean oil-based epoxy acrylate mixture and itaconic acid acrylate is 6:4.

Abstract

The invention discloses bio-based multifunctional flame-retardant epoxy acrylate and a preparation method and application thereof. The bio-based multifunctional flame-retardant epoxy acrylate prepolymer is prepared in two modes, diethyl phosphoacetic acid is introduced into bio-based epoxy resin through a ring-opening esterification reaction, the flame-retardant effect can be effectively achieved, and thus the flame resistance of a cured film is enhanced; the resorcinol diglycidyl ether and the epoxidized vegetable oil are used as main raw materials to prepare the multifunctional bio-based epoxy acrylate, so that biomass can be effectively introduced into a photocureable coating, and the use of petroleum-based raw materials is reduced; itaconic acid is selected to replace (methyl) acrylic acid derived from petroleum products, so that the application of biomass in the photocureable coating is increased; and the ring-opening reaction of itaconic acid and epoxidized vegetable oil has a chain extension effect on the polymer, is also beneficial to improving the functionality of epoxidized vegetable oil-based acrylate, and improves the flexibility, tensile strength and other related properties of a photocureable film.

Description

technical field [0001] The invention belongs to the field of UV curing materials, and in particular relates to a bio-based multifunctional flame-retardant epoxy acrylate and a preparation method and application thereof. Background technique [0002] At present, most of the materials used in life are flammable, such as plastics, rubber, fibers, and wood that are often in contact with. Adding a layer of flame retardant cured film on the surface of these materials is beneficial to improve the flame resistance of the material. Flame retardants can generally be divided into additive flame retardants and reactive flame retardants. Additive flame retardants are mixed with polymer materials by physical methods; reactive flame retardants are added as a monomer Polymerization, because it has a flame retardant component, has little effect on the performance of polymer materials, and the flame retardancy will be longer. At present, most reactive flame retardants are prepared by reacti...
