Embodiment 1

[0031] A kind of white board paper is made from the following raw materials in parts by weight: 85 parts of mixed fiber, 6 parts of persimmon peel extract and 15 parts of semichemical pulp. Wherein, 85 parts of the mixed fibers include mango tree fiber and bamboo fiber with a mass ratio of 15:2, and the length of the mango tree fiber is 0.85 mm and the width is 0.02 mm.

[0032] The preparation method of the persimmon skin extract is as follows: dry and pulverize the persimmon skin, add it to an aqueous solution of acetone to avoid light and reflux for extraction, filter after the first extraction, perform 2 times of reflux extraction on the filter residue, and 3 times of reflux to extract The filtrates were combined, the acetone was removed by distillation under reduced pressure, and the filtrate was concentrated and freeze-dried to obtain final product; wherein, the amount of acetone added each time was 3 times that of the persimmon skin quality.

Embodiment 3

[0057] A kind of white board paper is made from the following raw materials in parts by weight: 90 parts of mixed fiber, 7 parts of persimmon peel extract and 18 parts of semichemical pulp. Wherein, 90 parts of the mixed fibers include mango tree fiber and bamboo fiber with a mass ratio of 15:2, and the length of the mango tree fiber is 0.85 mm and the width is 0.02 mm.

[0058] The preparation method of the persimmon skin extract is as follows: dry and pulverize the persimmon skin, add it to an aqueous solution of acetone to avoid light and reflux for extraction, filter after the first extraction, perform 2 times of reflux extraction on the filter residue, and 3 times of reflux to extract The filtrates were combined, the acetone was removed by distillation under reduced pressure, and the filtrate was concentrated and freeze-dried to obtain final product; wherein, the amount of acetone added each time was 4 times that of the persimmon skin quality.

Abstract

The invention discloses a white paperboard and a method for manufacturing the same. The white paperboard comprises, by weight, 85-95 parts of mixed fibers, 6-8 parts of persimmon peel extract and 15-22 parts of semi-chemical pulp. The mixed fibers include mango tree fibers and bamboo fibers, a mass ratio of the mango tree fibers to the bamboo fibers is 15-16:2-3, the lengths of the mango tree fibers are 0.85 mm, and the widths of the mango tree fibers are 0.02 mm. The white paper board and the method have the advantages that the shortcoming of existing white paperboards in the aspect of elasticity can be overcome by the aid of the white paperboard with a low formaldehyde content, the white paperboard is difficult to fluff and high in smoothness, and printing ink is easy to attach onto the white paperboard.

Description

technical field [0001] The present invention relates to the field of papermaking. More specifically, the present invention relates to a production process of white board paper. Background technique [0002] Due to the relatively uniform fiber structure of white board paper, the surface layer has filler and rubber components, and the surface is coated with a certain amount of paint, and has been processed by multi-roller calendering, so the texture of the cardboard is relatively tight and the thickness is relatively uniform. The paper surface is generally whiter and smoother, with more uniform ink absorption, less dusting and hair loss on the surface, stronger paper quality and better folding resistance, but its water content is higher , generally around 10%, there is a certain degree of flexibility, which will have a certain impact on printing. The difference between whiteboard paper and coated paper, offset paper, and letterpress paper lies in the weight of the paper, thi...
