Abstract
The invention relates to a scratch-resistant coating for pen-writing wall cloth and a preparation method of the scratch-resistant coating, and belongs to the technical field of coatings, the preparation method of the coating comprises the following steps: cleaning dust and greasy dirt on the surface of the pen-writing wall cloth, after plastering, puttying and sand repairing, coating the surface of the pen-writing wall cloth with a coating by using a roller coater, and drying to obtain the scratch-resistant coating for the pen-writing wall cloth. The coating is self-made, the acrylic resin with the acid value and the viscosity in a proper range is adaptively selected in the coating self-making process, the refraction coefficient of the polyester resin is reduced, the transparency is improved, epsilon-polylysine is added to be inserted in a molecular chain of a polyester resin system in a penetrating mode, ordered arrangement of the molecular chain is destroyed, and the transparency is improved. The modified material is added, and ester groups, hydroxyl groups and cyclohexyl groups are introduced to reduce the crystallinity of the system, so that the prepared polyester resin is used for preparing a coating, and the transparency of the coating can be effectively improved; meanwhile, the modified polysiloxane master batch and erucyl amide are also added, so that the scratch resistance of the prepared coating is improved.
