Abstract
The invention relates to an organic polymer composite material, in particular to rapid prototyping plastic. The plastic comprises the following components in percentage by weight: 56-95.5 percent of nylon 66, 2.5-15 percent of molybdenum bisulfide, 0.3-3.5 percent of antioxidant, 0.1-4.2 percent of heat stabilizer, 0.1-2.9 percent of coupling agent, 0.1-3.0 percent of silicon oil with high molecular weight, 0.5-5.5 percent of activated carbon and 0.3-5.5 percent of emulsifying agent. According to the plastic disclosed by the invention, several agents with a certain proportion are added, so that the prototyping period of the plastic is shortened while certain physical performance of the plastic is ensured and the production efficiency can be improved to a great degree.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of rapid shaping plastics.
Background technology
China Plastics Industry is through secular struggle with towards the opening in the whole world; Formed the more complete industrial system of class; Become the base mateiral industry of running neck and neck with steel, cement, timber, as a kind of type material, its use field surmounts above-mentioned three kinds of materials far away and has got into since 21 century; China Plastics Industry has obtained achievement attracting people's attention, has realized historical leap.As the plastic industry of one of light industry mainstay industry, rate of growth remained on more than 10% always in recent years, and when keeping very fast tempo, economic benefit also has new raising.
Nylon 66 is to use one of several kinds of maximum engineering plastics at present; Be widely used in the component of making various machineries, automobile, chemical industry, electronics and electrical means; His fusing point is higher; Have good physical and mechanical property and wear resistance and self lubricity, be particularly suitable for HS or wear-resisting product, these comprehensive characteristics are that other plastics are not available.But social technology develop rapidly at present; Make rapid progress; The product innovation ditty pours out, and relates to requirement for picture and can effectively significantly reduce frictional coefficient, simultaneously the stronger component of starting material self wear resistance; The plurality of advantages of common nylon 66 lets the designer favor very much, but but above-mentioned shortcoming lets people's headache very much.The starting material that provided in the market with above-mentioned functions; Or nylon 12 these types are expensive, or add the additive material of the such costliness of tetrafluoroethylene, cause material cost high equally; Like this, also require relative starting material of starting material and production cost lower.
Have moulding nylon 66 products faster on the market now, still, effect is not clearly yet, has so just delayed the speed of producing, and wherein physical and mechanical properties neither be very high.
Summary of the invention
The objective of the invention is to effectively overcome the defective of prior art, a kind of rapid shaping plastic raw materials with self lubricity preferably and wear resistance is provided.
Technical scheme provided by the invention is following: a kind of rapid shaping plastics of the present invention, by following composition by weight forming nylon 66:56-95.5%, molybdenum disulphide powder: 2.5-15%; Inhibitor: 0.3-3.5%; Thermo-stabilizer: 0.1-4.2%; Coupling agent: 0.1-2.9%; HMW silicone oil: 0.1-3.0%; Gac: 0.5-5.5%; Emulsifying agent: 0.3-5.5%.
Rapid shaping plastics-production flow process of the present invention is: at first, in the aqueous solution of nylon 66, add emulsifying agent, and under mechanical stirring or vibration; Monomer nylon 66 forms emulsion and the polymerization carried out in water. and in order to make the plastics that make outside possessing general mechanical property, make that also plastics can rapid shaping, letex polymerization can be under higher speed of response; Add an amount of molybdenum disulphide powder, inhibitor, thermo-stabilizer, coupling agent, HMW silicone oil, gac and can obtain the polymkeric substance of higher molecular weight; Remove residual monomer nylon 66 then, obtain solid nylon 66 through technological processs such as cohesions, separation, washing at last, fully soak nylon 66 with 50% salt solution saturated solution again; Behind 105 ℃ of following prepared in reaction nylon 66 powders; Obtain raw material, raw material are put in certain mould, heating and pressurizing; The high-temperature calcination dehydration, cooling obtains required plastics again.
The advantage of a kind of rapid shaping plastics of the present invention: through the adding of several kinds of reagent; Can be so that plastic shaping cycle weak point; Can improve production efficiency of products largely, also can guarantee physical and mechanical properties simultaneously, improve the speed of producing greatly; Enterprise can be mass-produced, and has also improved the competitive power of product on market so simultaneously greatly.
Embodiment
Below be the most preferred embodiment of rapid shaping plastic raw materials of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of rapid shaping plastics are provided, by following composition by weight forming nylon 66:78.5%, molybdenum disulphide powder: 7.8%; Inhibitor: 3.2%; Thermo-stabilizer: 1.7%; Coupling agent: 2.1%; HMW silicone oil: 2.7%; Gac: 1.5%; Emulsifying agent: 2.5%.
At first, in the aqueous solution of nylon 66, add emulsifying agent, and under mechanical stirring or vibration; Monomer nylon 66 forms emulsion and the polymerization carried out in water. and letex polymerization can be under higher speed of response, adds the polymkeric substance that an amount of molybdenum disulphide powder, inhibitor, thermo-stabilizer, coupling agent, HMW silicone oil, gac can obtain higher molecular weight, removes residual monomer nylon 66 then; Obtain solid nylon 66 through technological processs such as cohesion, separation, washings at last; Fully soak nylon 66 with 50% salt solution saturated solution again, behind 105 ℃ of following prepared in reaction nylon 66 powders, obtain raw material; Raw material are put in certain mould; Heating and pressurizing, the high-temperature calcination dehydration, cooling obtains required plastics again.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
