Abstract

The invention relates to a quartz sand gypsum palette with a grinding sand texture. A preparation method comprises the steps of adding 240 to 260 parts of deionized water, 1.5 to 2.5 parts of defoaming agent, 18 to 23 parts of propylene glycol and 3.5 to 6.5 parts of dispersing agent into a reaction kettle and stirring; continuously adding 95 to 105 parts of titanium dioxide powder, 240 to 260 parts of talcum powder and 240 to 250 parts of quartz sand of 200 meshes; dispersing for 1 to 1.5 hours; adding 140 to 160 parts of pure acrylic emulsion and evenly stirring; adding a multifunctional additive AMP-95 and regulating a pH value to 7.0; adding 1.8 to 2.5 parts of defoaming agent, 8.5 to 11.5 parts of film-forming aiding agent and 4 to 6 parts of thickening agent under a stirring condition; continuously stirring so as to obtain a coating paint; spraying the costing paint on a picture frame made of wood plates so as to obtain the quartz sand gypsum palette with a grinding sand texture. The quartz sand gypsum palette is excellent in water resistance and weather resistance; a coating layer has the grinding sand texture, and is good in firmness and flintiness, strong in stereoscopic impression and difficult to crack due to the fact that the coating paint is sprayed thickly. In addition, the coating layer can be polished to reach any thickness, and a good shower coating effect can be obtained if the coating paint is matched with a shower coating process.

Description

technical field [0001] The invention relates to an art painting utensil, in particular to a quartz sand hard gypsum drawing board with frosted texture. Background technique [0002] Gypsum material is cheap and beautiful, and it is a very good coating material for drawing boards. However, gypsum drawing boards are prone to yellowing, cracking and deformation after prolonged storage, and the gypsum material lacks texture, hardness and three-dimensional effect. Contents of the invention [0003] In view of the above-mentioned defects existing in the existing gypsum drawing board, the object of the present invention is to provide a kind of frosted texture quartz sand gypsum drawing board. The gypsum drawing board of the present invention has excellent water resistance and weather resistance, the coating has a frosted texture, good firmness and hardness, strong three-dimensional effect, thick coating is not easy to crack, and can be polished to any thickness, and the matching ...
