Abstract

The utility model discloses a kind of temperature-sensitive board, including the transparency glass plate (3) set gradually from top to down, heat-sensitive variable colour interlayer (2) and white glass substrate (1), the edge of the transparency glass plate (3) and white glass substrate (1) by adhesive it is glued together and by heat-sensitive variable colour interlayer (2) encapsulation between, reversible thermochromism material is full of in the heat-sensitive variable colour interlayer, the writing of word is carried out using raising board local temperature and showing color change, then recover the original color of board after local temperature is reduced, during without being wiped, it is easy to use.

Description

A kind of temperature-sensitive board

Technical field

The utility model is related to a kind of board, more particularly to a kind of temperature-sensitive board.

Background technology

In daily learning life, blackboard or blank are most common apparatus, and blackboard can be produced often in use The problems such as pollution, dust, and blank then there are problems that dazzling and wipe sordid.

Utility model content

The purpose of this utility model is to provide a kind of board, using raising the local temperature of board and show face Color change carries out the writing of word, after then recovering the original color of board after local temperature reduction, during without be wiped Wipe, it is easy to use.

The purpose of this utility model is achieved through the following technical solutions：

A kind of temperature-sensitive board, including transparency glass plate, heat-sensitive variable colour interlayer and the white glass set gradually from top to down The edge of glass substrate, the transparency glass plate and white glass substrate is glued together and by heat-sensitive variable colour interlayer by adhesive Encapsulation between, is full of reversible thermochromism material in the heat-sensitive variable colour interlayer.

Further, the reversible thermochromism material is uniformly mixed by the component of following parts by weight：Peacock green 3 Part, 50 parts of trichloroacetic acid, 100 parts of polystyrene and 30 parts of benzene.

Further, the thickness of the heat-sensitive variable colour interlayer is 0.1-0.3cm, and the thickness of the transparency glass plate is 0.2- 0.4cm。

Further, white glass substrate can coat the glass plate of white paint for white pmma plate or in bottom.

The beneficial effects of the utility model are, using the color change of reversible thermochromism material at different temperatures, will Board is made between being placed in two pieces of glass plates in it, and usable heating pen writes, and improves the local temperature of board and produces color The change in pool, after after temperature recovery, the color of board is then recovered as before, easy to use without being wiped to it.

Brief description of the drawings

The temperature-sensitive writing board structure schematic diagram of Fig. 1 the utility model embodiment 1.

Wherein, Fig. 1 (a) is temperature-sensitive board front view, and Fig. 1 (b) is temperature-sensitive board A-A sectional views.

Embodiment

Explanation is further explained to the utility model below in conjunction with specific embodiments and the drawings.

A kind of temperature-sensitive board, including transparency glass plate 3, heat-sensitive variable colour interlayer 2 and the white set gradually from top to down Glass substrate 1, the edge of the transparency glass plate 3 and white glass substrate 1 is glued together and become temperature-sensitive by adhesive 4 Color interlayer 2 is encapsulated between, and reversible thermochromism material is full of in the heat-sensitive variable colour interlayer.

The reversible thermochromism material is uniformly mixed by the component of following parts by weight：3 parts of peacock green, trichloroacetic acid 30 parts of 50 parts, 100 parts of polystyrene and benzene.The material shows faint yellow when less than 50 DEG C, and green is shown at 50-100 DEG C.

To reach preferable color developing effect, the thickness of the heat-sensitive variable colour interlayer is 0.1-0.3cm, the transparency glass plate 3 thickness is 0.2-0.4cm.

The white glass substrate 1 can coat the glass plate of white paint for white pmma plate or in bottom surface.

Electrical heating pen can be used to be write on temperature-sensitive board, the written temperature of electrical heating should at 80-100 DEG C, This electrical heating pen can be using structure described in patent CN91214101.8.Improve the local temperature of board and produce color Change, after after temperature recovery, the color of board is then recovered as before, easy to use without being wiped to it.
