Abstract

The invention relates to the field of coating paper preparation, in particular to a preparation method of coating paper. The method comprises following steps: (1), base paper is soaked in an impregnating adhesive containing modified urea-formaldehyde resin, a penetrating agent, a curing agent and water, rolled by a roller and dried in a drying oven; (2), a spraying adhesive containing modified melamino-formaldehyde resin, the modified urea-formaldehyde resin, the penetrating agent, a suspending agent, a defoaming agent, the curing agent, aluminium oxide and water is sprayed to the upper surface of the paper obtained in step (1) by spraying equipment, and then the paper is leveled by a leveling roller and dried in the drying oven; (3), the front and back surfaces of the paper obtained in step (2) are coated with a mesh coating adhesive containing the modified melamino-formaldehyde resin, a mold release agent, a dedusting agent, the curing agent and water by a round roller with a grid structure, and then the paper is dried in the drying oven. According to the method, the coating paper with both wear-resistant effect and decorative effect can be prepared, and forest resources are saved.

Description

technical field [0001] The invention relates to the field of spray-coated paper manufacture, in particular to a preparation method of spray-coated paper. Background technique [0002] With the heating up of the real estate industry, people's requirements for living environment and working environment are constantly improving, and people pay more and more attention to the quality of house decoration. As an important part of the overall decoration of the house, the decoration of the floor will inevitably receive great attention from the relevant market. [0003] In the floor production process, in order to make the floor look more beautiful, a layer of decorative paper is usually covered on the surface of the floor; at the same time, in order to enhance the wear resistance of the floor and prolong the service life of the floor, it is also necessary to cover a layer of durable paper on the surface of the floor. grinding paper. [0004] In order to make the floor look beautifu...
