Problems solved by technology

Sand is difficult to shape, so using sand as raw material to make shaped handicrafts with different styles, there is no good process. The only way to make handicrafts with sand is to spray sand on plastic, gypsum and other forming materials. However, the produced handicrafts lack texture, the sand is easy to fall off, the surface finish is poor, and it is not beautiful.

Description

technical field [0001] The invention relates to a handicraft, in particular to a sand plastic handicraft and its manufacturing process. Background technique [0002] Sand is widely distributed in deserts, beaches and riverbeds, etc., and has not been used for other purposes except in the field of construction. Sand is difficult to form, so there is no good process to use sand as raw material to make shaped handicrafts with different styles. The only way to make handicrafts with sand is to spray sand on plastic, gypsum and other forming materials. However, the produced handicraft lacks texture, the sand is easy to fall off, the surface finish is poor, and it is not beautiful. Contents of the invention [0003] The object of the present invention is to provide a sand plastic handicraft with reasonable ratio, strong plasticity, good compactness, and the ability to maintain the original color of sand and its manufacturing process. [0004] To achieve the above object, the pr...
