Abstract
The present invention relates to a non-radioactive environment-protecting energy-storing luminous plastic mother granule, and is characterized by that the rare earth luminous material is added into the plastic raw material, the weight ratio of plastic raw material and rare earth luminous material is 70:30, and the described luminous material is made up by using the raw materials of strontium carbonate, aluminium oxide, boric acid, europium sesquioxide and dysprosium oxide, etc. through the roasting process. Said invention has the advantages of having no radioactive substance and long luminous time.
Description
Technical field
The present invention relates to a kind of non-radioactive environment protective energy storage luminous plastics mother granule, it is raw material production that described luminous plastics mother granule adopts inactive rare earth material.
Technical background
It is main raw material that existing photoluminescence plastic material all adopts zinc sulphide.Chinese patent 92108547.8 discloses a kind of luminophore composition that contains phosphor.Said composition is combined by zinc sulphide and cupric sulfide and a certain amount of activator.This material has stronger luminosity, continues fluorescent lifetime in the dark and can reach 12 hours, can be widely used in industries such as safety features, building, electrical equipment, public transport, textile printing and dyeing, exploitation, production.But this material has certain radioactivity, and accumulation of energy is lower.To have a negative impact to environment and human body if use this material to make plastic prod, therefore, need to propose a kind of non-radioactive environment protective energy storage luminous plastics mother granule.
Summary of the invention
The object of the present invention is to provide a kind of non-radioactive environment protective energy storage luminous plastics mother granule, this luminous plastics mother granule does not contain harmful radioactive substance, and has higher accumulation of energy.
The objective of the invention is to realize by following technical proposals: a kind of non-radioactive environment protective energy storage luminous plastics mother granule, its main points are: add rare earth luminescent material in plastic raw materials, the weight ratio of plastic raw materials and rare earth luminescent material is 70: 30; Described luminescent material is formed by following feedstock production, and the weight ratio of described raw material is:
Strontium carbonate powder 37-38
Aluminium sesquioxide 26-27
Boric acid 3-5
Europiumsesquioxide 0.46-0.7
Dysprosium trioxide 0.9-1.
The present invention compared with prior art has following advantage:
1, makes raw material owing to active materials such as not adopting zinc sulphide in the plastic master batch of the present invention, so can not produce harmful radioactive substance.
2, because the present invention has adopted rare earth luminous raw material, therefore, plastics of the present invention have the ability of stronger savings luminous energy, and the plastic prod that uses the present invention to make only need receive about illumination 10-20 minute, just can keep in the environment of dark luminous about 20 hours.
Embodiment
Embodiment one:

Luminescent material and plastic raw materials thorough mixing are processed into plastic master batch by granulating equipment.
Described plastic raw materials can be polyethylene, polypropylene, polyphenyl alkene, polyvinyl chloride, polystyrene.
Embodiment two:
Non-radioactive environment protective energy storage luminous plastics mother granule is to add rare earth luminescent material in plastic raw materials, and the weight ratio of plastic raw materials and rare earth luminescent material is 70: 30; Described luminescent material is formed by following feedstock production, and the weight ratio of described raw material is:
Strontium carbonate powder 37.7
Aluminium sesquioxide 26.8
Boric acid 3.9
Europiumsesquioxide 0.462
Dysprosium trioxide 0.98.Luminescent material preparation technology flow process in the present embodiment is identical with embodiment one.Luminescent material and plastic raw materials thorough mixing are processed into plastic master batch by granulating equipment.Described plastic raw materials can be polyethylene, polypropylene, polyphenyl alkene, polyvinyl chloride, polystyrene.
