Description
Technical field
The present invention relates to a kind of chemical industry synthetic materials, be specifically related to a kind of modified polyolefin plastics.
Background technology
Mineral filler such as calcium carbonate, mica, wollastonite, talcum, kaolin etc., because have unique physicochemical property, can improve mechanical property, processing characteristics and the thermal characteristics etc. of polymkeric substance, and the application development in polymkeric substance is very fast.It is exactly increment that the effect of mineral filler in polymer composites sums up, strengthen and give new function.But, due to mineral filler and organic polymer intermiscibility very poor, if directly added, can cause and disperse unevenly, and the large person of particle diameter also can become the focal point of stress in matrix material, becomes the weak link in material.These drawbacks have not only limited the addition of filler in polymkeric substance, but also have a strong impact on product properties, so by mineral filler is carried out to surface modification, change the original surface properties of mineral filler, affinity, intermiscibility and processing fluidity, the dispersiveness of mineral filler and polymkeric substance are improved, can also improve the bonding force between filled polymers phase interface, the over-all properties of matrix material is significantly improved, thereby make the mineral filler of NOT-function change functional stuffing into.In recent years, along with the fast development of polymer composites, the process for modifying surface of mineral filler has also received unprecedented concern.
Summary of the invention
The object of the invention is to overcome the defect of prior art and a kind of modified polyolefin plastics are provided; it has the situation that reaches service requirements in the product performance feature cheaply that declines; can also degrade, be conducive to eliminate " white pollution ", protection of the environment and the ecosystem.
Realizing a kind of technical scheme of object of the present invention is: a kind of modified polyolefin plastics, and it comprises following each composition by weight ratio: polyolefine 10-15%, pearl filler 70-75%, auxiliary agent 5-6%, properties-correcting agent 5-6%; Described pearl filler is taking Wingdale as raw material, the high-speed mixer that is 120-150 DEG C through excess temperature mix and pass through plasticizing, granulation forms.
Above-mentioned modified polyolefin plastics, wherein, described auxiliary agent is polyethylene wax; Described properties-correcting agent is aluminate coupling agent.
Above-mentioned modified polyolefin plastics, wherein, the high-speed mixer that described auxiliary agent and properties-correcting agent are 120-150 DEG C through excess temperature respectively mix and pass through plasticizing, granulation forms.
Realizing the another kind of technical scheme of object of the present invention is: a kind of degradable modified polyolefin plastics, it comprises following each composition by weight ratio: polyolefine 10-15%, pearl filler 70-75%, auxiliary agent 4-5%, properties-correcting agent 4-5%, degradation agents 0.5-2%; Described pearl filler is taking Wingdale as raw material, the high-speed mixer that is 120-150 DEG C through excess temperature mix and pass through plasticizing, granulation forms.
Above-mentioned degradable modified polyolefin plastics, wherein, described auxiliary agent is polyethylene wax; Described properties-correcting agent is aluminate coupling agent.
Above-mentioned degradable modified polyolefin plastics, wherein, the high-speed mixer that described auxiliary agent and properties-correcting agent are 120-150 DEG C through excess temperature respectively mix and pass through plasticizing, granulation forms.
Above-mentioned degradable modified polyolefin plastics, wherein, described degradation agents is ethene/carbon monoxide multipolymer.
Modified polyolefin plastics of the present invention, adopting Wingdale inexpensive, that easily purchase is raw material, the filler forming through special process processing and refining, and add in plastics, its addition is up to 70-75%, its cost is only 25% of conventional plastic, and its proportioning can be according to produced product performance and allotment ratio and granulation process temperature.If add after degradation agents in this material, coordinate with common polyolefine with it and can produce cost also lower than the degredation plastic film of conventional plastic, packing bag, mess-tin etc.Therefore modified polyolefin plastics of the present invention, have the situation that reaches service requirements in the product performance feature cheaply that declines, and can also degrade, and are conducive to eliminate " white pollution ", protection of the environment and the ecosystem.
Embodiment
The invention will be further described below.
A kind of modified polyolefin plastics of the present invention, it comprises following each composition by weight ratio: polyolefine 10-15%, pearl filler 70-75%, auxiliary agent: polyethylene wax 5-6%, properties-correcting agent: aluminate coupling agent 5-6%, wherein, pearl filler is taking Wingdale as raw material, the high-speed mixer that is 120-150 DEG C through excess temperature mix and pass through plasticizing, granulation forms.The high-speed mixer that auxiliary agent and properties-correcting agent are also 120-150 DEG C through excess temperature respectively mix and pass through plasticizing, granulation forms; Auxiliary agent and properties-correcting agent can be allocated proportioning and regulate granulation process temperature according to produced product performance; Do not need granulation if plastic raw materials is powder, after only needing to mix thoroughly, can use.
The degradable modified polyolefin plastics of one of the present invention, it comprises following each composition by weight ratio: polyolefine 10-15%, pearl filler 70-75%, auxiliary agent: polyethylene wax 4-5%, properties-correcting agent: aluminate coupling agent 4-5%, degradation agents: ethene/carbon monoxide multipolymer 0.5-2%, wherein, pearl filler is taking Wingdale as raw material, the high-speed mixer that is 120-150 DEG C through excess temperature mix and pass through plasticizing, granulation forms.The high-speed mixer that auxiliary agent and properties-correcting agent are also 120-150 DEG C through excess temperature respectively mix and pass through plasticizing, granulation forms; Auxiliary agent and properties-correcting agent can be allocated proportioning and regulate granulation process temperature according to produced product performance; Do not need granulation if plastic raw materials is powder, after only needing to mix thoroughly, can use.
Embodiment 1, configures 100 kilograms of modified polyolefin plastics, and it comprises following each composition by weight ratio: 13 kilograms of polyolefine, 75 kilograms of pearl fillers, 6 kilograms of auxiliary agents, 6 kilograms of properties-correcting agent.
