[0002] White board paper refers to white cardboard or flipchart paper. White board paper is divided into two categories: printing and stationery. Printing white board is a cardboard with a white and smooth front and a gray back. This type of cardboard is mainly used for single-sided color printing and then made into paper boxes for packaging, or for design and handicrafts. Stationery white board is a stack of flipchart paper, mainly suitable for seminars, workshops, meetings, etc. The size is slightly smaller than 1K and there are various specifications, the most common ones are: 560mm*850mm, 600mm*900mm.

[0003] However, existing white paperboard is usually formed by stacking multiple layers of paper and then pressing them. The structural strength of the paper is limited and it is easy to be damaged when subjected to excessive force. As a result, the structural strength of the white paperboard is low and there is a risk of damage when subjected to excessive force. Therefore, it does not meet the existing needs. In this regard, we have proposed a white paperboard that is not easy to be damaged. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] like Figures 1 to 4 As shown, a white paper that is not easy to be damaged includes a first outer paper 1 and a second outer paper 2. The first outer paper 1 is located below the second outer paper 2. An intermediate connecting paper 3 is provided between the first outer paper 1 and the second outer paper 2. The intermediate connecting paper 3 is fixed to the first outer paper 1 and the second outer paper 2 by adhesive bonding. The intermediate connecting paper 3 includes a buffer support cardboard 34. The buffer support cardboard 34 is wavy curved. Multiple groups of buffer support members are provided between the buffer support cardboard 34 and the first outer paper 1 and the second outer paper 2. The buffer support member is composed of multiple linear The buffer support blocks 36 are arranged in an array. The buffer support blocks 36 on the same straight line are adhered with adhesive strips 35 on the surface facing the first outer layer of paper 1 or the second outer layer of paper 2. The adhesive strips 35 are bonded to the first outer layer of paper 1 or the second outer layer of paper 2 by glue. The buffer support cardboard 34 and the buffer support blocks 36 are used to support and buffer between the first outer layer of paper 1 and the second outer layer of paper 2, thereby reducing the pressure on the first outer layer of paper 1 and the second outer layer of paper 2, and preventing the first outer layer of paper 1 and the second outer layer of paper 2 from being damaged due to excessive pressure.

[0020] The surface of the buffer support block 36 facing the buffer support cardboard 34 is curved and fits the surface curvature of the buffer support cardboard 34. The buffer support block 36 is made of rubber. A buffer groove 37 is provided between the ends of each two adjacent buffer support blocks 36. The buffer support block 36 is solid inside and has good elasticity and can recover after compression. After being compressed, the buffer support block 36 elastically deforms and offsets the pressure on the first outer layer of paper 1 and the second outer layer of paper 2, and elastically recovers the first outer layer of paper 1 after the pressure on the first outer layer of paper 1 disappears.

[0021] A filling paper frame 31 is provided on the outside of the buffer support cardboard 34, and a layer of waterproof plastic film 33 is wrapped on the outside of the filling paper frame 31. The waterproof plastic film 33 is bonded to the first outer layer of paper 1 and the second outer layer of paper 2 by glue. The waterproof plastic film 33 is used to protect the filling paper frame 31, increase the strength of the filling paper frame 31, and prevent the filling paper frame 31 from being torn from the middle.

[0022] A circular hole is provided inside the filling paper frame 31 , and a filling rubber strip 32 is filled inside the circular hole. The filling rubber strip 32 increases the compression resistance and elastic recovery ability of the filling paper frame 31 and prevents the filling paper frame 31 from being torn from the middle.

[0023] Working principle: First, the buffer support block 36 is adhered to the mutually facing surfaces of the first outer paper 1 and the second outer paper 2 through the adhesive strip 35 and pressed tightly. Then, the second outer paper 2 is placed on the processing table, and the buffer support cardboard 34 is placed on the multiple buffer support blocks 36 on the surface of the second outer paper 2. Then, the filling paper frame 31 wrapped with the waterproof plastic film 33 is placed on the outside of the buffer support cardboard 34. Glue is applied on the upper surface of the waterproof plastic film 33 and the ground. Finally, the first outer paper 1 is covered on the buffer support cardboard 34. , the waterproof plastic film 33 is placed above the first outer layer of paper 1 and pressed tightly, so that the waterproof plastic film 33 is in close contact with the first outer layer of paper 1 and bonded and fixed to complete the processing of the white paper. When the surface of the white paper is subjected to pressure during use, the white paper is compressed toward the middle due to gravity. At this time, the buffer support cardboard 34 will change from a wavy curve to a straight line due to the pressure. At the same time, the buffer support block 36 is compressed and deformed, and the compressed buffer support block 36 absorbs and offsets the pressure on the white paper, thereby avoiding damage to the white paper due to excessive pressure.
