Problems solved by technology

[0002] Mirror silver resins are generally modified acrylic resins, and mirror silver resins in the prior art often have one or more of the following problems: 1. high temperature resistance is not satisfactory, 2. does not have broad-spectrum substrate adhesion , that is, the adaptability of the resin to the substrate is often not good, ③ the solvent resistance of the resin is poor, ④ the raw materials used or the synthesis process are not environmentally friendly; ⑤ the cost of the synthesis process is relatively high
[0003] For this reason, predecessors have done a lot of research work, Chinese patent CN102432777A, first synthesize active cellulose acetate butyrate intermediate, and then copolymerize with acrylic acid functional monomer, many steps, high cost

preparation example Construction

[0019] The preparation method of the above-mentioned high temperature-resistant mirror silver resin comprises the steps of: adding cellulose acetate butyrate in the first component into a solvent to dissolve, heating while stirring, raising the temperature to 70-95° C., and protecting with nitrogen gas; Mix all the materials in the second component, add dropwise to the first component in 3.5-4.5 hours, keep warm for 1-1.5 hours, and raise the temperature to 85-110°C; add the third component, keep warm for 2-2.5 hours, and finally Cool and filter.

[0020] Preferably, the cellulose acetate butyrate is at least one of CAB381-0.1, CAB381-0.5, CAB381-2, and CAB381-20.

[0021] Described initiator is oil-soluble peroxide or azo compound; Preferably, described oil-soluble peroxide is benzoyl peroxide, tert-butyl peroxybenzoate, dicumyl peroxide, peroxide At least one of di-tert-butyl oxide and methyl ethyl ketone peroxide; the azo compound is at least one of azobisisobutyronitrile ...

Embodiment 1

[0025] Nitrogen was blown in the four-neck flask, 200 parts of butyl acetate and 50 parts of xylene were added, stirred while heating, then 50 parts of CAB381-2 was added to dissolve, and the temperature was raised to 80°C. Start dropping the following mixture, 40 parts of methyl methacrylate\20 parts of butyl acetate\10 parts of hydroxyethyl methacrylate\10 parts of hydroxypropyl methacrylate\40 parts of epoxy methacrylate\ 1 part of initiator, azobisisobutyronitrile, was dripped in 4 hours, and kept warm for 1 hour after dripping. Add 1 part of azobisisobutyronitrile\20 parts of butyl acetate, keep warm for 2 hours, and filter.

Embodiment 2

[0027] Nitrogen was blown in the four-neck flask, 300 parts of ethylene glycol methyl ether acetate was added, stirred while heating, then 50 parts of CAB381-20 was added to dissolve, and the temperature was raised to 85-90°C. Start dropping the following mixture, 50 parts of methyl methacrylate\20 parts of butyl acetate\10 parts of hydroxyethyl methacrylate\10 parts of hydroxypropyl methacrylate\30 parts of epoxy methacrylate\ Mix 10 parts of isobornyl methacrylate\1.5 parts of benzoyl peroxide, drop it in 4 hours, and keep it warm for 1 hour after the drop. Add 1 part of benzoyl peroxide\20 parts of butyl acetate, keep warm for 2 hours, and filter.

Abstract

The invention discloses a high-temperature-resistant mirror silver resin which is prepared from the following raw materials: first components comprising cellulose acetate butyrate and a solvent; second components comprising methyl methacrylate, butyl methacrylate acetate, hydroxyethyl methacrylate, hydroxypropyl methacrylate, epoxy methylacrylate, vinyl siloxane, isobornyl methacrylate, lauryl methacrylate, acrylic acid and an initiator; and third components comprising an initiator and a solvent. A preparation method of the mirror silver resin comprises the steps of adding cellulose acetate butyrate of the first components into the solvent, dissolving, heating while stirring, heating up to 70-95 DEG C, and introducing nitrogen gas; mixing the second components, dropwise adding into the first components, carrying out heat preservation, and heating up to 85-110 DEG C; and adding the third components, carrying out heat preservation, and finally cooling and filtering. The prepared silver mirror resin has high temperature resistant performance, and has a broad-spectrum adhesive force to a base material; the product has relatively good solvent resistance; and the synthesis process is green and environmentally friendly.
