Problems solved by technology

The disadvantages of this dry-erase whiteboard are: 1. There are many production processes, the structure of the composition is complicated, and it is not easy to operate.
2. Since the multi-layer boards are glued together by glue, they are easy to volatilize and produce toxic gases
3. Increased production costs
In the production process, raw materials such as composite PVC are added, which increases the cost of raw materials
4. The temperature of the hot pressing process is too high, the energy consumption is greater, and it is difficult to realize that the plate does not deform and warp under high temperature

Embodiment Construction

[0023] A kind of preparation method of writing board provided by the invention comprises steps:

[0024] 1. Assemble the high-gloss stainless steel template and the cushion pad into the single-layer hot press, put the cushion pad between the hot-press plate of the single-layer hot press and the high-gloss stainless steel template, and install it on the frame Multiple vacuum suction cups are used to transfer the MDF board, and send the MDF board to the designated position of the heat press.

[0025] 2. Through the air blowing and dust removal device installed on the frame, each medium density fiberboard is blown and dust removed;

[0026] 3. Assemble the blank, cover the melamine-impregnated film paper on the medium-density fiberboard, and ensure that the melamine-impregnated film paper is all covered on the surface of the medium-density fiberboard, so that the slab is formed;

[0027] 4. Send the slab into the hot press, close the single-layer hot press, start pressing, contr...

Abstract

The invention discloses a writing board and a production method thereof. The method includes assembling a high-luminance stainless steel template and a cushion into a single-layer hot press, and putting the cushion between a hot press plate of the single-layer hot press and the high-luminance stainless steel template; blowing and dedusting each middle-density fiber plate; covering melamine steeped bond paper on the middle-density fiber plates to form a plate blank; feeding the plate blank into the hot press, closing the single-layer hot press to start pressing, and controlling the hot press temperature at 190-200 DEG C, the hot press pressure at 25-28kg / cm<2> and the hot press time for 16-25 seconds to acquire the writing board. By the method, operation procedure is simplified, cost is reduced, and production efficiency and product quality are improved; temperature of hot press technology is low, hot press time is short, easiness in control and operation is realized, and plates does not deform and warp; product surfaces are smooth and compact, so that written words can be erased easily without any solvent.

Description

technical field [0001] The invention relates to a stationery product, in particular to a writing board which is made of an artificial board with impregnated film and paper veneer. Background technique [0002] With the improvement of people's living standards and the development of spiritual and cultural construction, the number of children learning calligraphy and painting is also increasing year by year. In order to reduce the consumption of resources, in some respects, the writing board is used instead of ordinary paper. In order to solve the technical problems of repeated use, the writing board uses a variety of materials and structures. [0003] Patent document CN201471958U discloses a dry-erase whiteboard, which adheres a layer of specially-treated composite PVC on the surface of the density board to make it dry-erase. Composite PVC board is composed of PVC, composite surface hardening layer, UV dry-erase coating, UV dry-erase coating, composite surface hardening lay...
