Abstract

The invention provides a polypropylene writable plate and its preparation process. The polypropylene writable plate comprises a polypropylene sheet and a coating formed by coating an ink composition. The ink composition consists of the following parts by weight: Component composition: 100 parts of PP ink, 10-20 parts of matting agent, 40-60 parts of thinner, 1-5 parts of curing agent, 1-3 parts of coupling agent, 3-5 parts of polydimethylsiloxane, mica Powder 3~5 parts, antioxidant 2~5 parts. The coating on the surface of polypropylene writable board is prepared by screen printing process. After coating a layer of coating on the surface of polypropylene, the purpose of changing the smoothness of the surface of polypropylene can be achieved, so that it can be processed on the surface of polypropylene. Writing, and the handwriting after writing is not easy to be erased.

Description

technical field [0001] The invention relates to the field of stationery, in particular to a polypropylene writable board and a preparation process thereof. Background technique [0002] Polypropylene is a very common plastic at present. It has been used in all aspects of life. Polypropylene is cheap, non-toxic, odorless, low density, and has excellent strength, stiffness, hardness and heat resistance. , but the surface of the polypropylene sheet is smooth, so it is difficult to write on the surface of the polypropylene sheet. wipe. In order to change the non-writable shortcomings of polypropylene, it is necessary to coat a layer of coating on the surface of polypropylene, thereby changing the inherent characteristics of polypropylene, so that writing can be performed on this layer, but the combination of coating and polypropylene is not strong It will cause the coating to fall off when writing, affecting the use effect. [0003] A publication number is CN 1101653A, and th...
