Embodiment 1

[0018] First, mix 60 parts of LDPE2420H, 20 parts of LLDPE920NT, 10 parts of PC polycarbonate, and 10 parts of nano-flame-retardant composites by weight percentage to make the outer layer raw material. Mix 35 parts of LDPE2420H, Stir 65 parts of LLDPE920NT evenly to make the middle layer raw material, mix 25 parts of LDPE2426H, 25 parts of MDPE5401, 25 parts of LLDPE218W, 24 parts of LLDPE920NT, and 1 part of PC polycarbonate to make the inner material The original mixed material of the layer is then mixed with the outer layer raw mixed material, the middle layer raw mixed material and the inner layer raw mixed material according to the weight percentage by 40 parts of the outer layer, 20 parts of the middle layer, and 40 parts of the inner layer. After the batching is completed, it can be used The film blowing machine equipped with automatic batching equipment is blown to produce the required film.

Embodiment 2

[0020] First, stir 55 parts of LDPE2420H, 25 parts of LLDPE920NT, 10 parts of PC polycarbonate, and 10 parts of nano-flame-retardant composites to make the outer layer raw material by weight percentage, and mix 30 parts of LDPE2420H, Stir 70 parts of LLDPE920NT evenly to make the middle layer raw material, mix 20 parts of LDPE2426H, 30 parts of MDPE5401, 20 parts of LLDPE218W, 20 parts of LLDPE920NT, and 10 parts of PC polycarbonate to make the inner layer by weight percentage Raw mixed materials, according to the percentage by weight, the outer layer raw mixed materials, the middle layer raw mixed materials, and the inner layer raw mixed materials are batched according to 40 parts of the outer layer, 20 parts of the middle layer, and 40 parts of the inner layer. After the batching is completed, it can be used. The film blowing machine with automatic batching equipment is blown to produce the required film.

Embodiment 3

[0022] First, 48 parts by weight of LDPE2420H, 16 parts of LLDPE920NT, 16 parts of PC polycarbonate, and 20 parts of nano-flame-retardant composites were evenly stirred to make the outer layer raw material, and 40 parts by weight of LDPE2420H, Stir 60 parts of LLDPE920NT evenly to make the middle layer raw material, mix 30 parts of LDPE2426H, 20 parts of MDPE5401, 25 parts of LLDPE218W, 20 parts of LLDPE920NT, and 5 parts of PC polycarbonate to make the inner layer by weight percentage Raw mixed materials, according to the percentage by weight, the outer layer raw mixed materials, the middle layer raw mixed materials, and the inner layer raw mixed materials are batched according to 40 parts of the outer layer, 20 parts of the middle layer, and 40 parts of the inner layer. After the batching is completed, it can be used. The film blowing machine with automatic batching equipment is blown to produce the required film.

[0023] After many tests, it has been proved that PC polycar...

Abstract

The invention relates to a high-strength nano-film. The high-strength nano-film comprises three parts, namely an outer layer, a middle layer and an inner layer, wherein the outer layer accounts for 40% by weight, the middle layer accounts for 20% by weight, and the inner layer accounts for 40% by weight; the variety and amount of adjuvant added to the outer and inner layers are determined through tests, thus the strength of a product can be improved as much as possible on the basis that the original properties of the product are not damaged. The invention further provides a production method of the film, which comprises the steps of (1) mixing materials; (2) proportioning the materials; (3) carrying out film blowing. The film provided by the invention has the characteristics of high surface flatness, easiness in being subjected to corona, easiness in cladding and high strength, and continuous production can be realized through a film blowing machine by combining material proportioning equipment.

Description

technical field [0001] The invention relates to the field of film production and processing, in particular to a high-strength nano film and a production method thereof. Background technique [0002] Blowing film (Blow Membrane) is a plastic processing method, which refers to a plastic processing technology in which plastic particles are heated and melted and then blown into a film. If it is a film blown out of new materials, the color is uniform and clean, and the finished product is stretched well. If the plastic particles made of recycled waste plastics are usually added with pigments when made into a film, the resulting film may be unevenly colored, brittle and easily broken, and the price is relatively low. The blown film materials produced by professional film blowing machines are suitable for various high-grade film packaging. This film can be widely used in light and heavy packaging due to its good barrier properties, freshness preservation, moisture resistance, fro...
