Problems solved by technology

[0003] The main problems of plant fiber papermaking that people have used for more than 2,000 years are: (1) wasting a lot of forest and water resources; (2) emitting a lot of organic chlorides and toxic gases, polluting the environment, destroying ecological balance and endangering personal safety; (3) High water absorption, not waterproof and moisture-proof, which limits the scope of use; (4) Large ink consumption, high cost, and high paper price; (5) Complex process and high energy consumption

Embodiment 1

[0037] A modified polyolefin paper without plant fibers, which is composed of a first base layer 1, a second base layer 2 and a third base layer 3.

[0038] The first base layer 1 and the third base layer 3 are composed of 30% ethylene-acrylic acid modified copolymer EAA, 48% metallocene high-density polyethylene, 20% activated ultrafine inorganic powder with a particle size of 5000 mesh and additives. Prepared as antistatic agent lauryl dimethyl betaine 2%.

[0039] The second base layer 2 between the first base layer 1 and the third base layer 3 is made of 60% activated ultrafine inorganic powder with a particle size of 3500 meshes, 5% maleic anhydride, and high-density polyethylene 33, and the second A base layer 1, a second base layer 2 and a third base layer 3 are combined into an integral structure. The first base layer 1 and the third base layer 3 respectively account for 8% of the total weight of the paper, and the second base layer 2 accounts for 84% of the total wei...

Embodiment 2

[0041] A modified polyolefin paper without plant fibers is composed of a first matrix layer 1, a second matrix layer 2 and a third matrix layer 3 combined into a whole.

[0042] The first base layer 1 and the third base layer 3 are respectively composed of ethylene-acrylic acid modified copolymer EAA 20%, metallocene high-density polyethylene 59%, 3000-5000 mesh activated ultrafine inorganic powder 20% and additives Static agent lauryl dimethyl betaine 1% prepared.

[0043] The second matrix layer 2 is made of activated ultrafine inorganic powder with a particle size of 1000-1500 mesh, namely 70% talcum powder, 5% maleic anhydride and 25% high-density polyethylene. The above percentages are percentages by weight. The first and third substrate layers each constitute 10% of the total weight of the paper, and the second substrate layer represents 80% of the total weight of the paper.

Embodiment 3

[0045] A modified polyolefin paper without plant fibers is composed of a first matrix layer 1, a second matrix layer 2 and a third matrix layer 3 combined into a whole.

[0046] The first base layer 1 and the third base layer 3 are respectively composed of 25% of ethylene-acrylic acid modified copolymer EAA, 49.5% of metallocene high-density polyethylene mHDPE, 23% of ultrafine inorganic body talcum powder with a particle size of 3000-5000 mesh and The additive is prepared from 2.5% aluminate.

[0047] The second matrix layer 2 is prepared from 70% of superfine inorganic body talcum powder with a particle size of 1000-1500 mesh, 4% of maleic acid, 24% of high-density polyethylene and 2% of low-molecular polyethylene as an auxiliary agent.

[0048] The above percentages are percentages by weight. The first base layer 1 and the third base layer 3 respectively account for 9% of the total weight of the paper, and the second base layer accounts for 82% of the total weight of the p...

Abstract

The invention discloses modified polyolefin paper without plant fiber. The modified polyolefin paper is formed by a matrix layer 1 without the plant fiber, a matrix layer 2 without the plant fiber and a matrix layer 3 without the plant fiber which are compounded into a whole, wherein the matrix layer 1 and the matrix layer 3 are 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 respectively, and the matrix layer 2 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 be used as industrial paper, packing paper and household paper, can 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, and 3.7 tons of wood chips are needed to produce one ton of paper, which is equivalent to cutting down 20 large trees with a growth period of 20-40 years, and using fresh water at the...
