Modified polyolefins paper without plant fibre

Abstract

The invention discloses modified polyolefin paper without plant fiber. The modified polyolefin paper is formed by a first matrix layer without the plant fiber, a second matrix layer without the plant fiber and a third matrix layer without the plant fiber which are compounded into a whole, wherein the first matrix layer and the third matrix layer are respectively prepared by 20 to 30 percent of ethylene-acrylic acid modified copolymer EAA, 45 to 60 percent of metallocene high-density polyethylene mHDPE, and 20 to 25 percent of activated ultrafine inorganic powder by using an aluminate F-2 type coupling agent, and the second matrix layer is prepared by 60 to 90 percent of activated ultrafine inorganic powder, 2 to 5 percent of maleic anhydride and 8 to 35 percent of high-density polyethylene. The modified polyolefin paper has the advantages of good ink receptivity and softness. Therefore, the modified polyolefin paper can not only be used as industrial paper, packing paper and household paper, but also be used as cultural paper, and enlarges the use range. The modified polyolefin paper has higher foldability and rigidity, has the longitudinal and transverse tearing strength which are superior to those of plant fiber paper, has good surface flattening, good handwriting, and clear printing performance, saves printing ink, has simple production technology, protects forest resources, saves energy sources and water, reduces the discharge of organic chlorides and harmful gas, has no waste, and protects the environment.

Description

technical field

[0001] The invention relates to a kind of paper, in particular to a modified polyolefin paper without plant fiber, which can be used for cultural paper, industrial paper, packaging paper, household paper and special paper. Background technique

[0002] At present, the paper used in industry, culture, packaging, household and special use in my country is all made of wood, reed, straw or bagasse. With the rapid development of the economy and the continuous improvement of the people's cultural level, the scope of application of paper is becoming wider and wider, and the amount of use is increasing, which also puts forward higher requirements for the performance and quality of paper. The natural plant fibers needed for papermaking, especially wood and reeds, are increasingly scarce. To produce one ton of paper requires 3.7 tons of wood chips, which is equivalent to cutting down 20 large trees with a growth period of 20-40 years, and using fresh water at the same ...
