Problems solved by technology

But the ensuing problem is that as the proportion of calcium carbonate increases, its functional effect gradually decreases, and the physical and mechanical properties of the prepared stone paper decrease accordingly, resulting in a decrease in the quality of the stone paper.
On the other hand, although the proportion of calcium carbonate increases and the proportion of resin decreases, the specific gravity of the prepared stone paper increases, which instead causes the actual production of paper to decrease, thus compressing the actual space for cost reduction

preparation example Construction

[0044] The preparation method of the three-layer co-extrusion environment-friendly stone paper provided by the invention, such as figure 2 As shown, including: A. Dry all component materials until the water content is less than 2%, so as to ensure the smooth progress of the entire process. B. Add the middle layer material and the surface layer material respectively into the high-speed mixer and mix and stir at 100-110°C. The mixing order is as follows: the middle layer material: first stir the short fibers for 3-5 minutes, then add the additives and stir for 3-5 minutes, mix After uniformity, add resin and stir for 3-5 minutes; surface material: first stir titanium dioxide for 3-5 minutes, then add additives and stir for 3-5 minutes, mix well, add resin and stir for 3-5 minutes. C. Vacuum knead the mixed middle layer material and surface layer material respectively and then granulate to obtain surface layer particles and middle layer particles respectively; D send the surface...

Abstract

The invention relates to the field of papermaking, and discloses a novel environment-friendly stone paper and a preparation method thereof. The invention provides a novel environment-friendly stone paper using short fiber to substitute a main component calcium carbonate in a traditional stone paper. The invention further provides a three-layer coextrusion environment-friendly stone paper. The environment-friendly stone paper is composed of a three-layer structure comprising a surface layer-a middle layer-a surface layer; the middle layer comprises main components of short fiber and resin; and the surface layer comprises main components of titanium dioxide and resin. Compared with performance of the traditional stone paper, the novel environment-friendly stone paper, prepared from processes comprising mixing, kneading, granulation and calendering, gains reduced specific gravity, improved physical and mechanical properties and increased size, and qualitatively changes definition, characteristics, advantages and application fields of stone paper, and has extensive application value.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a novel environment-friendly stone paper and a preparation process thereof. Background technique [0002] Paper is one of the four great inventions of China. The main raw material of traditional paper is wood, etc. Its production is roughly divided into two basic processes: pulping and papermaking. Pulping is to dissociate raw materials into natural pulp or bleached pulp. Papermaking is to process pulp fibers suspended in water into paper that meets the requirements. At present, with the introduction of the national forest protection policy, papermaking raw materials mainly rely on imported wood pulp. At the same time, due to the large amount of waste water produced in the traditional paper production process, which seriously pollutes the environment, it is extremely difficult to treat it. In addition, traditional paper is not resistant to moisture, corrosion, dimensional stability ...
