Polymer composite paperboard and preparation method thereof

Abstract

The invention discloses a polymer composite paperboard and a preparation method thereof. The polymer composite paperboard is prepared from the following raw materials in parts by weight: 80-120 partsof low-density polyvinyl chloride, 30-50 parts of polypropylene, 120-160 parts of calcium carbonate, 10-20 parts of polyethylene wax, 15-25 parts of a borate coupling agent, 4-8 parts of ground calcium carbonate, 4-8 parts of light calcium carbonate and 10-18 parts of color master batch. Wood pulp is not needed, forest wood is prevented from being cut down, and the environment is prevented from being damaged. The polymer composite paperboard can be used for hand bags, gift bags and the like, can also be widely used for posters, year cards and the like, and has the characteristics of high strength, good tear resistance, good flame retardance, good acid and alkali resistance, good printability, writability, durability and the like. In addition, the polymer composite paperboard is good in calendering effect, stable and reliable, and is very convenient and reliable in installation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of paperboard, and in particular relates to a polymer composite paperboard and a preparation method thereof. Background technique [0002] Nowadays, paper has become an indispensable part of people's life. As the most traditional and oldest information recording carrier, it is widely used in packaging materials, sanitary materials, environmental protection tableware and other fields. China has become the largest of paper products consuming countries. With the rapid development of the economy and the continuous improvement of people's living standards, people's excessive use and over-reliance on paper makes people's demand for paper still increase year by year. At present, in the process of cardboard production, a large amount of wood pulp is required, so a large amount of forest resources need to be cut down. At the same time, the production process will cause pollution to water resources and damage to the ...

AI Technical Summary

Problems solved by technology

At present, in the process of cardboard production, a large amount of wood pulp is needed, so a large amount of forest resources need to be cut down. At the same time, the production process will cause pollution to water resources and damage to the air environment. The production process is relatively complicated. Paper toughness is poor, and its production equipment calender structure is complex, installation and maintenance are very complicated, stability and reliability are poor, and it cannot meet the needs of use
