Embodiment 1

[0014] First, by weight percentage, 60% LDPE2420H, 30% LLDPE920NT, 5% PBT polybutylene terephthalate, and 5% PPO polyphenylene ether are stirred evenly to make the outer layer original mixed material. Stir 35% of LDPE2420H and 65% of LLDPE920NT evenly to make the middle layer original mixed material, mix 25% of LDPE2426H, 25% of MDPE5401, 25% of LLDPE218W, 24% of LLDPE920NT, 1% of PBT polyparaphenylene Butylene glycol diformate is stirred evenly to make the inner layer original mixed material, and then the outer layer original mixed material, the middle layer original mixed material, and the inner layer original mixed material are made into 40% of the outer layer, 20% of the middle layer, and 40% of the inner layer by weight percentage. After the batching is completed, the film blowing machine equipped with automatic batching equipment can be blown to produce the required film.

Embodiment 2

[0016] First, mix 55% of LDPE2420H, 25% of LLDPE920NT, 10% of PBT polybutylene terephthalate, and 10% of PPO polyphenylene ether by weight percentage to make the outer layer of the original mixed material, by weight percentage Stir 30% of LDPE2420H and 70% of LLDPE920NT evenly to make the middle-layer original mixed material, and mix 20% of LDPE2426H, 30% of MDPE5401, 20% of LLDPE218W, 25% of LLDPE920NT, and 5% of PBT polyparaphenylene Butylene glycol diformate is stirred evenly to make the inner layer original mixed material, and then the outer layer original mixed material, the middle layer original mixed material, and the inner layer original mixed material are made into 40% of the outer layer, 20% of the middle layer, and 40% of the inner layer by weight percentage. After the batching is completed, the film blowing machine equipped with automatic batching equipment can be blown to produce the required film.

Embodiment 3

[0018] First, mix 58% of LDPE2420H, 26% of LLDPE920NT, 8% of PBT polybutylene terephthalate, and 8% of PPO polyphenylene ether by weight percentage to make the outer layer of the original mixed material. Stir 40% of LDPE2420H and 60% of LLDPE920NT evenly to make the middle-layer original mixed material, mix 30% of LDPE2426H, 20% of MDPE5401, 27% of LLDPE218W, 20% of LLDPE920NT, and 3% of PBT polyparaphenylene Butylene glycol diformate is stirred evenly to make the inner layer original mixed material, and then the outer layer original mixed material, the middle layer original mixed material, and the inner layer original mixed material are made into 40% of the outer layer, 20% of the middle layer, and 40% of the inner layer by weight percentage. After the batching is completed, the film blowing machine equipped with automatic batching equipment can be blown to produce the required film.

[0019] After many tests, it has been proved that PBT polybutylene terephthalate and PPO pol...

Abstract

The invention relates to a high-temperature-resistant wear-resistant film. The 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. According to the film, raw materials for improving the wear resistance and high-temperature tolerance of the film are added into the outer layer, and meanwhile, raw materials for improving the high-temperature resistance of the film are added into the inner layer, so that the quality of the film is improved. 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, high-temperature resistance and wear resistance, 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-temperature and wear-resistant 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, moistur...
