Embodiment 1

[0041] Prepare materials by weight:

[0042]

[0043]

[0044] Put 100 parts of ethanol into the reactor with condensation back, mix the monomers evenly and add them to the dropping device, and add 1.8 parts of initiator to the dropping device with 20 parts of ethanol solvent. Heat the ethanol in the reactor to 72°C, feed nitrogen gas, start to drop the monomer solution and initiator solution, control the flow rate, control the monomer solution within 3-3.5h to complete the dropwise addition, and control the initiator solution at 4-4.5 After the dropwise addition of h, the reaction was incubated at 75° C. for one hour. The obtained resin solution is vacuum degassed to recover the solvent, cooled and pulverized to obtain powdered resin.

Embodiment 2

[0046] Prepare materials by weight:

[0047]

[0048] Put 120 parts of ethanol into the reactor with condensation back, mix the monomers evenly and add them to the dropping device, and add 1.6 parts of initiator to the dropping device with 30 parts of ethanol solvent. Heat the ethanol in the reactor to 60-65°C, feed nitrogen gas, start to drop the monomer solution and initiator solution, control the flow rate, control the monomer solution within 3-3.5h to complete the dropwise addition, and control the initiator solution at 4 ~4.5h after the dropwise addition, keep the reaction at 62°C for one hour. The obtained resin solution is vacuum degassed to recover the solvent, cooled and pulverized to obtain powdered resin.

[0049] The specific synthesis process refers to Example 1, the difference is that the reaction temperature should be lowered to 60-65° C., because the initiation temperature of azobisisoheptylnitrile is lower than that of azobisisoheptylnitrile.

Embodiment 3

[0051] Prepare materials by weight:

[0052]

[0053]

[0054] Put 110 parts of ethanol into the reactor with condensation back, evenly add 1.6 parts of initiator and monomer mixed solvent into the dropping device, heat the ethanol in the reactor to 72°C, blow in nitrogen, and start dropping Monomer solution and initiator solution, control the flow rate, the monomer solution is controlled to be added dropwise within 3-3.5 hours, and a solution of 0.4 parts of initiator and 30 parts of ethanol is added, controlled to be dropped within 1-1.5 hours, and then kept at 75°C Respond for an hour. The obtained resin solution is vacuum degassed to recover the solvent, cooled and pulverized to obtain powdered resin.

[0055] The difference from Examples 1 and 2 is that azobisisobutyronitrile has low solubility in ethanol, so a part is used to dissolve in the monomer, and then a part of azobisisobutyronitrile ethanol solution is added.

Abstract

The invention relates to an acrylic ester powdered resin having a self-cleaning property and a synthesizing method thereof. The acrylic ester powdered resin comprises the following components in part by weight: 8-15 parts of polymeric carboxylic acids, 40-60 parts of methyl methacrylates, 10-25 parts of butyl acrylates, 10-30 parts of butyl methacrylates, 5-20 parts of fluorinated monomers, 10-20 parts of methyl isobornyl thiocyanoacetates and 1.5-3.5 parts of initiating agents. Several conventional acrylate monomers, isobornyl acrylate monomers and fluorinated acrylate monomers are copolymerized, degassed, crushed and like, thereby acquiring the powdered acrylic resin having an excellent property. Compared with the prior art, the resin synthesized according to the synthesizing method has excellent ageing resistance and scraping resistance as well as self-cleaning property, contains no VOC (Volatile Organic Compounds) and has water solubility.

Description

technical field [0001] The invention relates to a powder resin and a synthesis method thereof, in particular to an acrylate powder resin with self-cleaning performance and a synthesis method thereof. Background technique [0002] As countries around the world are increasingly concerned about environmental protection and related pollution prevention and control regulations are becoming increasingly stringent, the resin manufacturing industry has undergone revolutionary changes in the past few years, that is, the original high-pollution solvent-based resins have been transformed into low-pollution resins. Environmentally friendly resins can include 100% solid resins, water-based resins and powder solid resins. The viscosity of 100% solid resin is too high, and the domestic equipment cannot keep up with it at this stage, and the construction is difficult; water-based resins generally need to add small molecule emulsifiers, which will have a certain impact on the performance of ...
