Inorganic powder highly filled polyolefin fiber paper and production method thereof

Abstract

The invention discloses inorganic powder highly filled polyolefin fiber paper and a production method thereof. The polyolefin fiber paper is prepared from the raw materials in proportion: 10% to 20% of polyolefin, 0.1% to 2% of coupling agent, 0.1% to 1% of dispersing agent, 1% to 10% of compatibilizer, 0.1% to 2% of plasticizer, 1 to 5% of hot-melt type adhesive, 0.1% to 2% of surface active agent, 0.1% to 1.5% of rheology modifier and 75% to 85% of inorganic powder. The production method comprises the steps of evenly mixing and stirring polyolefin and the rheology modifier under the assistance of a technology to improve a melt index and fluidity of polyolefin; sequentially adding the compatibilizer and the plasticizer to be evenly stirring and mixed; then sequentially adding the activated inorganic powder and the activated hot-melt type adhesive and evenly mixing and stirring; processing through the work procedures of mixing, kneading, drawing fiber, preparing a finished product fromfiber stuff and the like to obtain the inorganic powder highly filled polyolefin fiber paper. According to the inorganic powder highly filled polyolefin fiber paper disclosed by the invention high filling of inorganic powder is achieved, a resin use amount is reduced, tensile strength, impact strength and surface smoothness of the product are enhanced, and a filler retention rate is improved.

Description

technical field [0001] The invention belongs to the field of inorganic fiber paper, in particular to a polyolefin fiber paper highly filled with inorganic powder, and further relates to a polyolefin fiber paper highly filled with inorganic powder and a manufacturing method thereof. Background technique [0002] 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, hygiene materials, environmental protection tableware and other fields. China has become the largest paper manufacturer. product consuming countries. [0003] With the rapid development of the national economy, the demand for paper continues to increase. The raw material of traditional papermaking is wood pulp made from trees, and the papermaking industry consumes a lot of valuable forest resources, water resources and energy. In particular, a large amount of waste water, waste gas and waste residue prod...
