Abstract

The invention discloses acrylic resin with the self-crosslinking characteristic and a preparation method thereof. The acrylic resin is made from the raw materials with the following weight percentage of 25 percent to 30 percent of normal butanol, 10 percent to 16 percent of dimethylbenzene, 2 percent to 5 percent of pom, 4 percent to 7 percent of acrylamide, 12 percent to 18 percent of butyl methacrylate, 15 percent to 20 percent of butyl acrylate, 2 percent to 5 percent of acrylic acid, 12 percent to 16 percent of styrene, 0.1 percent to 0.3 percent of U626 antioxidants, 0.6 percent to 1.5 percent of BOP and 4 percent to 8 percent of butyl acetate. The invention can self cross link to form indissoluble and non-fusible coatings under a certain roasting temperature without the addition of cross linking agents due to containing the self-crosslinking groups, also can coordinate with the resin containing epoxy groups, hydroxyl groups and carboxy groups to prepare the coatings with different performances, therefore, the invention has the excellent application characteristic, and has a wide application range.

Description

Technical field

[0001] The invention relates to a synthetic resin, specifically a synthetic resin with a self-crosslinking group. The invention also relates to a process for preparing the synthetic resin. Background technique

[0002] At present, the acrylic resin for baking paint needs to be combined with an amino resin to cure and become a coating film with the required properties. Therefore, it is very inconvenient to apply, and the coating film is often caused by the incompatibility of the matching amino resin and acrylic resin. There may be insufficient gloss, hardness, and poor appearance. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides an acrylic resin that can be self-crosslinked and can also be copolymerized with resins containing epoxy groups, hydroxyl groups and carboxyl groups.

[0004] Another object of the present invention is to provide a method for producing the above-mentioned acrylic resin...

Examples

Embodiment Construction

[0023] An acrylic resin with self-crosslinking characteristics, which is made of the following raw materials in weight percentage: n-butanol 25-30%, xylene 10-16%, polyoxymethylene 2-5%, acrylamide 4-7% , Butyl methacrylate 12 to 18%, butyl acrylate 15 to 20%, acrylic acid 2 to 5%, styrene 12 to 16%, U626 antioxidant 0.1 to 0.3%, BOP 0.6 to 1.5% and butyl acetate Ester 4-8%.

[0024] The polyoxymethylene used in the present invention is a raw material imported from Germany, and the BPO requirements are produced by French Atofile Company. In addition, the n-butanol has a water content of ≤0.1% and a purity of ≥99.5%, the butyl acrylate and butyl acrylate , The purity of acrylic acid and styrene ≥99%.

[0025] The best weight percentage of an acrylic resin with self-crosslinking characteristics: n-butanol 27%, xylene 12%, polyoxymethylene 3%, acrylamide 5%, butyl methacrylate 14%, butyl acrylate 16% , Acrylic acid 3%, styrene 14%, U626 antioxidant 0.2%, BOP 0.8% and butyl acetate 5%...
