Abstract

The utility model provides a water displaying excise board which is reusable and harmless to the heath of children, and does not damage the periphery small environment. The technical scheme is as follows: the surface of a body printed with patterns and characters is provided with a transparent hydrophobic coating, and a hydrophilic coating is arranged outside of the hydrophobic coating corresponding to the position of a pattern and character painting region. The water displaying exercise board has the following beneficial effects that: when the water displaying exercise board is used, a user writes with clean water instead of the traditional pen containing colored pigments such as a crayon and a water-color brush, therefore, the invisible harm of heavy metal elements to children is reduced, the cleaning for clothes, desks and chairs, walls and the like is also reduced, moreover, the water displaying exercise board can be reused, therefore, the wastage rate is reduced, and the water displaying exercise board complies with the trend of low carbon and environment friendliness.

Description

Water shows practice board

Technical field

The utility model relates to the child and learns preceding apparatus, and especially a kind of reusable water shows practice board.

Background technology

In child's childhood preschool education period, the head of a family can buy some drawing boards that both pictures and texts are excellent, digital alphabet training book etc. to child, allows its scribble calculate.This common in the market series products or use the plain paper printing allows child carry out write once with versicolor crayon or watercolor pencil and draws, or through overlay film, writes picture with watercolor pencil.The book of plain paper printing can only disposablely use, be unfavorable for environmental protection, though the book of overlay film or drawing board can be wiped, but because child is smaller, can't oneself handle, need the head of a family to help to remove vestige, some head of a family does not want to take the trouble with its disposable use yet, this not only wastes resource, also is a kind of destruction to environment.In addition, all contain oil colour in crayon or the watercolor pencil, can draw when child uses table go up, on the clothes, wait and be everywhere on hand, on the face, easy cleaning not, and contents of heavy metal elements wherein is also than higher, and long-term contact meeting brings stealthy injury to child healthy.

Summary of the invention

The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, and provides a kind of reusable, can not bring injury to child's health, also can not show practice board by hurtful water to peripheral subenvironment.

For achieving the above object, the technical solution adopted in the utility model is that the surface that is printed with the base material of picture and text is provided with transparent hydrophobic coating, in the outside of hydrophobic coating, is provided with hydrophilic coating with corresponding position, picture and text full-filling zone.For increasing operation rate, the two sides of base material all is printed with picture and text, so the two sides of base material all is provided with transparent hydrophobic coating, in the outside of hydrophobic coating, is provided with hydrophilic coating with corresponding position, picture and text full-filling zone.

The beneficial effects of the utility model are: practice board is to write with clear water when using, no longer need to use traditional pens that contain colored pigment such as crayon, watercolor pencil, reduced the stealth injury of heavy metal element to child, also reduced the cleaning of clothing, tables and chairs, metope etc., and can reuse, reduce discarded rate, met the trend of low-carbon environment-friendly.

In conjunction with the accompanying drawings the utility model is further set forth below by embodiment, but following embodiment does not limit content of the present utility model.

The specific embodiment

Embodiment 1:

As Fig. 1, shown in Figure 2, water described in the utility model shows practice board, comprise the base material 1 that is printed with picture and text, base material 1 can be various materials such as paper, cardboard, plastic plate, yarn fabric, and the surface of base material 1 is provided with transparent hydrophobic coating 2, and the picture and text of printing on the base material 1 can be manifested clearly.Reserved in the picture and text as filling in arithmetic answer, word write, the zone of color full-filling etc. and child's interaction, in the outside of these regional hydrophobic coatings 2, the relevant position is provided with hydrophilic coating 3.The raw material that hydrophilic coating 3 adopts is the aqueous high molecular emulsion, what adopt in the present embodiment is to be raw material with polyvinyl alcohol (PVA) and tetraethoxysilane (TEOS), PVA/SiO2 organic inorganic hybridization colloidal sol by the IN-SITU SOL-GEL preparation, have the remarkable environmental safety feature, safe, nontoxic, harmless, do not fire not quick-fried, almost the non-volatility organic gas produces.

Child scribbles at the practice board respective regions as long as use to fill the pen of running water, and hydrophilic coating 3 absorbs and can become behind the moisture content transparently, manifests the pattern or the literal of printing on the base material 1, also can carry out freely creating.Water evaporates after a period of time, hydrophilic coating can become milky again, covers the pattern on the base material 1, and practice board can be reused.

For increasing operation rate, water described in the utility model shows practice board, can be made into two-sidedly, promptly on the two sides of base material 1 hydrophobic coating 2 and hydrophilic coating 3 is set all.The coating that the utility model is set up does not change the structure of conventional picture and text product, can individual use, and also can bind into book form, or occur with the various forms of present picture and text product.

Claims

1. water shows practice board, comprises the base material (1) that is printed with picture and text, and it is characterized in that: the surface of base material (1) is provided with transparent hydrophobic coating (2), and the outside in hydrophobic coating (2) with corresponding position, picture and text full-filling zone, is provided with hydrophilic coating (3).

2. water according to claim 1 shows practice board, it is characterized in that: the two sides of base material (1) all is provided with transparent hydrophobic coating (2), and the outside in hydrophobic coating (2) with corresponding position, picture and text full-filling zone, is provided with hydrophilic coating (3).
