Problems solved by technology
In the picture frame manufacturing industry, the following shortcomings generally exist in the prior art: 1. The viscosity of the picture frame adhesive is unreasonable, and the speed of the adhesive penetrating into the wood board is too fast or too slow, thereby affecting the bonding of the wood board contact surface
2. The strength of the photo frame adhesive itself is not enough, which affects the bonding quality
3. The curing speed of the photo frame adhesive itself is too slow, and the primer needs to be sprayed to increase the speed, which not only affects the work efficiency, but also affects the health of the operators and the environment

Abstract
The invention relates to a single-component photo frame adhesive which is prepared from the following raw materials in percentage by weight: 85-90% of alpha-ethyl cyanoacrylate; 8-11% of polymethacrylic resin; 1.0-2.0% of an accelerator; and 1.0-2.0% of a reinforcing agent. The single-component adhesive which is moderate in viscosity and can be used for quickly adhering plates is produced according to the formula disclosed by the invention, and a primer is prevented from being used, so that the processing and production efficiency of a wooden photo frame is further improved, and no additionalinfluence is generated on the health of workers and the environment; by adding propyl gallate, the strength of the adhesive is improved, and the current production requirement is met.
Description
technical field [0001] The invention relates to the technical field of alpha-cyanoacrylate ethyl ester adhesives, in particular to a picture frame adhesive and a preparation method thereof. Background technique [0002] α-cyanoacrylate compounds, due to their high anionic polymerization characteristics, are widely used in bonding steel, non-ferrous metals, rubber, leather, plastics, ceramics, glass, wood, etc. Wooden photo frames are used as a decoration in people's lives because of their natural and rustic characteristics. With the continuous improvement of people's living standards and aesthetic concepts, the market demand for wooden photo frames is also increasing. In the picture frame manufacturing industry, the following disadvantages generally exist in the prior art: 1. The viscosity of the picture frame adhesive is unreasonable, and the speed of the adhesive penetrating into the plank is too fast or too slow, thereby affecting the bonding of the contact surface of th...
