Abstract

The invention relates to the technical field of office stationery, and especially to a whiteboard and a manufacturing process thereof. The manufacturing process comprises the following steps: (1) taking a wood board, applying a layer of glue on one side of the wood board, and then sticking iron sheet; (2) pressing the wood board and the iron sheet with a pressure of 5-15 kg force for 2-4 days so as to obtain an adhesive board; (3) sealing the edge of the adhesive board with hot melt adhesive, and then fixing with a frame, coating the outer surface of the iron sheet with a layer of paint whichis easy to write and erase so as to make a whiteboard. The whiteboard prepared by the invention has the advantages of simple structure, easy inking, good repeated writing and wiping function, no colorstickiness, no discoloration, no dust, no trace, good scratch resistance and environmental protection.

Description

technical field [0001] The invention relates to the technical field of office stationery, in particular to a whiteboard and a manufacturing process thereof. Background technique [0002] As a kind of office stationery, whiteboard is usually a writing plane made of white metal plate material. The function of the whiteboard is similar to that of a blackboard, and it is a rewritable writing tool. Usually used for teaching, meeting discussions, or personal and family notes. Because the whiteboard has a wide range of functions and is less likely to generate dust than the traditional blackboard, this type of product is widely loved by people. Based on the above reasons, the whiteboard has a large market space. [0003] However, the existing whiteboard manufacturing process is more complicated, which increases the production cost, and the existing whiteboard can be erased after writing with a whiteboard marker, but it will leave traces, or it will lose its effect after a long ti...
