Abstract
The invention discloses a formula of foamed polyethylene plastic. The foamed polyethylene plastic comprises polyethylene plastic and additives, wherein the additives comprise fatty alcohol-polyoxyethylene ether sodium sulfate serving as a foaming agent, liquid polysulfide rubber serving as a softening agent, acrylate copolymer serving as a toughening agent, dicyclohexyl phthalate serving as a plasticizer, benzoyl peroxide serving as a cross-linking agent and vinyltriethoxysilane serving as a coupling agent. After the foaming agent and various auxiliary aids are added into the polyethylene plastic, the mechanical properties such as softness, toughness, tear resistance and plasticity of the foamed polyethylene plastic are greatly improved, and the service life of the foamed polyethylene plastic is prolonged; and the reaction rate of polyethylene in the production process can be improved, so that production cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of polyethylene foamed plastics.
Background technology
Along with the high speed development that Chinese national economy is built, equipment configurations such as a large amount of highly sensitive, high-precision electronics, opticinstrument, instrument appliance require the good packing of the high protective value of quality.Fields such as the railway that matches with the transportation of said product simultaneously,, navigation, aviation packed and transported also are starved of the protecting materials of excellent property.The polyethylene foamed research that China rises this year at the beginning that addresses this problem just, has obtained achievement a few days ago.
The polyethylene foamed resin is a foam, so heat insulating ability and heat retaining property are good and shock-absorbing capacity is also good.Weight is also light and be rich in flexibility in addition.Therefore be widely used in the protective sleeve of pad, cooling tube or the water pipe in various wrapping material, bathtub cover, bathroom.
But the product that existing polyethylene foamed material is processed can not get guaranteeing in mechanical properties such as flexibility, toughness, and cost is high, can not be popularized.
Summary of the invention
The object of the present invention is to provide the prescription of the polyethylene foamed plastics that a kind of softness is good, toughness is high, plasticity-good, cost is low.
Technical scheme of the present invention is that a kind of prescription of polyethylene foamed plastics comprises vinyon and additive; Described additive comprises whipping agent, flexibilizing agent, toughner, softening agent, linking agent and coupling agent, and described whipping agent is a polyoxyethylenated alcohol sodium sulfate, and flexibilizing agent is a liquid polysulfide rubber; Toughner is Yodo Sol GH 28; Softening agent is a dicyclohexyl phthalate, and linking agent is a Lucidol, and coupling agent is a vinyltriethoxysilane.
In preferred embodiment of the present invention; The weight proportion scope of each composition is that vinyon accounts for 74.7%-80.1% in the prescription of said polyethylene foamed plastics, and polyoxyethylenated alcohol sodium sulfate accounts for 6.2%-7.3%, and liquid polysulfide rubber accounts for 4.3%-5.4%; Yodo Sol GH 28 accounts for 3.7%-4.8%; Dicyclohexyl phthalate accounts for 2.6%-3.1%, and Lucidol accounts for 1.7%-2.5%, and vinyltriethoxysilane accounts for 1.4%-2.2%.
In preferred embodiment of the present invention; The weight proportion of each composition is that vinyon accounts for 77.8% in the prescription of said polyethylene foamed plastics, and polyoxyethylenated alcohol sodium sulfate accounts for 6.4%, and liquid polysulfide rubber accounts for 5.3%; Yodo Sol GH 28 accounts for 4.2%; Dicyclohexyl phthalate accounts for 2.9%, and Lucidol accounts for 1.9%, and vinyltriethoxysilane accounts for 1.5%.
According to the invention is a kind of prescription of polyethylene foamed plastics; After in vinyon, adding whipping agent and multiple auxiliary addition agent; The mechanical propertys such as flexibility, toughness, tear strength and plasticity-of polyethylene foamed plastics have been increased greatly; Increased the work-ing life of polyethylene foamed plastics, and owing to can accelerate poly in process of production speed of reaction, thereby greatly reduce production cost.
Embodiment
Set forth in detail in the face of preferred embodiment of the present invention down, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
