Description
Technical field
The present invention relates to the polyethylene reclaimed materials after the aluminum-plastic packaged material plastic-aluminum of a kind of waste and old toothpaste separates, particularly relate to a kind of PE modified particle of recovery of doing environment-friendly type emulsion explosive packing and preparation method thereof that can be used for.
Background technology
Along with the chemical industry development of technology, plastic prod makes rapid progress, and increasing plastics are applied to people's life, production field.According to statistics, the general-purpose plastics that accounts for total amount 70～80% in the present plastics of producing of China will be converted into plastic waste in 10 years, wherein have nearly half plastics will be converted into plastic waste in two years.The annual callable plastics of China are more than millions of tons, and China's technics of reclaim of plastic waste rate is lower in the world, only is about 15%; The rate of recovery of developed country's waste or used plastics is all about 50%.
Traditional waste plastic granulation is exactly with after the pre-treatment such as the sorting of waste or used plastics process, fragmentation, cleaning, drying, directly the tablets press extruding pelletization.The shortcoming of this method is that reworked material goods mechanical properties decrease is bigger, should not make high-grade goods, and is can direct applied scope very limited.Therefore, can take some method of modifying that waste or used plastics is carried out modification, improve the basic mechanical performance of waste plastic regeneration material, satisfy the quality requirement of finished proprietary item.
Summary of the invention
The object of the present invention is to provide a kind of performance deficiency that tradition reclaims plastic granulating that overcomes, improve and reclaim the particulate performance, degradation property is high can be used for PE modified particle of recovery of doing environment-friendly type emulsion explosive packing and preparation method thereof.
The technical solution used in the present invention is: a kind of environment-friendly type emulsion explosive packaging reclaims PE modified particle, it is characterized in that: be made up of the aluminum-plastic packaged recovery vinyon of waste and old toothpaste, photosensitizers, octylate compound, the special-purpose toughner of PE, the weight proportion of described each component is: 100 parts of the aluminum-plastic packaged recovery vinyons of waste and old toothpaste, 0.2-0.5 part of photosensitizers, 0.03-0.05 part of octylate compound, 1-3 parts of the special-purpose toughner of PE; Described photosensitizers is aromatic series ketone and st-yrax ethers material.
Described environment-friendly type emulsion explosive packaging reclaims PE modified particulate preparation method the aluminum-plastic packaged recovery vinyon of waste and old toothpaste, photosensitizers, octylate compound, the special-purpose toughner of PE is mixed in agitator according to the above ratio, the material that mixes is added single screw extrusion machine, temperature is controlled at 170 ℃～200 ℃, through after the fusion, extrude through two-layer 80 eye mesh screens, be automatically cut into particle by cutting machine.
The concrete processing parameter of described single screw extrusion machine is as follows:
Technological temperature (℃) 1 district, 2 districts, 3 districts, four district's heads
175±5 180±5 185±5 190±5 195±5
Melt pressure: melt pressure≤7.0MPa.
The present invention is in the aluminum-plastic packaged recovery vinyon of waste and old toothpaste, after adding photosensitizers, sad salt, the special-purpose toughner of PE, carry out the modification granulation, produce the PE modified particle of recovery that environment-friendly type emulsion explosive packing is made in high can be used for of degradation property.
The present invention makes the aluminum-plastic packaged recovery vinyon of waste and old toothpaste have photodegradation by adding photosensitizers and octylate compound.Under the irradiation of natural light, degradation property improves greatly, can degrade fully in four months basically, embodies the feature of environmental protection of product; By adding the special-purpose toughner of PE, can improve the chemical property of the aluminum-plastic packaged recovery vinyon of waste and old toothpaste, make every mechanical performance index of modified plastics be improved; The PE modified particle of recovery that obtains has not only overcome the performance deficiency of traditional recovery plastic grain, and has improved the degradation property that reclaims plastics, helps environment protection, has reduced environmental pollution.
