Problems solved by technology

[0002] In the production process of pencils, it is necessary to use adhesive components to complete the bonding of fibers or paper. At present, more environmentally friendly polyvinyl acetate adhesives are used, but the cold resistance of polyvinyl acetate emulsion, Water resistance, heat resistance, mechanical strength, etc. are poor, and they cannot be stored for a long time and used stably. It will also cause problems such as high scrap rate during pencil processing and use, poor performance, and instability.
Therefore, it needs to be improved, but the existing methods or products are likely to cause the problem that the improvement of one characteristic will cause the degradation of other performances, and the overall quality still needs further improvement.
