Novel flexible writing board and preparation method thereof

Abstract

The invention provides a novel flexible writing board which comprises a flexible base material. A writing layer is coated to one face of the flexible base material, and is suitable for writing with a whiteboard marker or a chalk; a lowly viscous organic silica gel layer is coated to the other face of the flexible base material, the organic silica gel layer is formed by multiple uniformly distributed lowly viscous salient point glue which are independently separated, and a release layer is compounded to the surface of the organic silica gel layer. The area of the organic silica gel layer is 30-80% of the area of the flexible base material. The novel flexible writing board provided by the invention can provide an application scheme which is good in exhausting property, can be pasted repeatedly to use and is wider in application range in the field of writing boards.

Description

technical field [0001] The invention belongs to the field of writing boards, in particular to a flexible and reusable functional writing board. Background technique [0002] Along with the development of society, the application of writing tablet is increasingly extensive. The existing writing boards are mainly installed in three ways: Most of the traditional whiteboard writing boards use rigid metal or composite boards as the base material, which is heavy and inconvenient to disassemble and carry. These products are fixed by pegs Installation and operation are complicated, and the substrate to be pasted will be damaged by mechanical damage; in order to improve the installation convenience of the writing board, some manufacturers have developed flexible writing boards, which can be pasted by double-sided tape or glue coated on the back of the writing board , In order to ensure a firm installation, this type of product uses a high-viscosity adhesive. After a long period of u...

Problems solved by technology

The existing writing boards are mainly installed in three ways: Most of the traditional whiteboard writing boards use rigid metal or composite boards as the base material, which are heavy and inconvenient to disassemble and carry. These products are fixed by pegs Installation and operation are complicated, and the substrate to be pasted will be damaged by mechanical damage; in order to improve the convenience of writing board installation, some manufacturers have developed flexible writing boards, which can be pasted by double-sided tape or glue coated on the back of the writing board , in order to ensure a firm installation, this type of product uses a high-viscosity adhesive. After a long period of use, the adhesive will remain on the surface of the substrate to be pasted, which is difficult to clean, and because the entire adhesive surface is bonded, the bubbles generated during the bonding will not be easy. In addition, due to the high viscosity of the adhesive, this type of product cannot be used on some substrates with relatively rough surfaces and relatively weak surface strength. For example, its application on latex paint walls will cause wall damage. The body is damaged, so the application field of the product is limited; there is also a special writing board that is pasted magnetically, the back of the writing board is coated or composite magnetic material, and is pasted on the metal substrate by magnetic force. This method has limited application range, non-metallic Not to be used on surface substrates
