Description
【Technical field】
The present invention relates to a kind of long-acting environment friendly releasing agent and preparation method thereof.
【Background technology】
Plastic mould accounts for consequence in modern industrial system, and with Design of Dies, advancing by leaps and bounds for process technology and continually developing for new material, increasing highly difficult, high accuracy, the product of high request are produced by the way of plastic mould injection.Diversified releasing agent is exactly to continue to bring out under such background, but existing releasing agent product suffers from following defect.1st, poor heat resistance, easily carbonization are decomposed so as to fail.2nd, pH value is presented acid, there is certain corrosiveness to mould.3rd, easily transfer, pollutes plasthetics, especially to the optics that has high demands or medicine equipment component.4th, environment is polluted, there is threat to the health of operating personnel.So a kind of permanent type releasing agent of environment-friendly high-efficiency has highly important meaning for the development for solving existing issue acceleration plastic mould.
【The content of the invention】
The present invention seeks to solve existing releasing agent pollution environment, easily failure, the easily shortcoming of transfer, there is provided a kind of to strengthen the corrosion-resistant and wear-resistant performance long-acting environment friendly releasing agent of mould.
Another object of the present invention is to provide a kind of preparation method of above-mentioned releasing agent.
The present invention is achieved by the following technical solutions：
A kind of long effective environmental protection type releasing agent, it is characterised in that including following components：NiSO4·6H2O, NaH2PO2·H2O, Na3C6H5O7·2H2O, C2H3NaO2CH3COONa, CuSO4, CH4N2S, PTFE particulate, graphite particulate, OTAC and deionized water.
The pH value of obtained releasing agent of the invention is 7.0, and corrosion will not be caused to die surface.
Octadecyl in the present invention can be such that the graphite particulate and PTFE particulates of addition is evenly distributed in releasing agent to be not susceptible to precipitate or chromatograph, make system more stable as emulsifying agent.
The particle diameter of PTFE particulates and graphite particulate in the present invention is 0.1-0.8 μm, 0.2 μm of preferable particle size.
In the present invention, PTF PARTICLE Es and graphite particulate suffer from high temperature resistant, self-lubricating, do not adhere to, the advantage of acid and alkali-resistance.Various composition in releasing agent generates composite bed under interaction, and both particulates are firmly fixed on into die surface so as to play the good demoulding and corrosion resistant effect.Specifically action principle is the present invention：Graphite particulate and PTFE particulates are uniformly suspended in releasing agent in the presence of stabilizer OTAC, and when releasing agent is directed onto heated die surface, graphite particulate and PTFE particulates are covered in die surface due to physisorption.At the same time NiSO4·6H2O and CuSO4By NaH2PO2·H2O is reduced, and generates one layer of laminated film being made up of Ni-P-Cu and by these particle encapsulations in die surface rapidly.These particulates are just become by physical absorption and are embedded in die surface.
The content of each component of the present invention is as follows：
Further, the concrete content of each component of the present invention is as follows：
The concrete consumption from water is removed in the present invention to be settled to aequum as principle.
Releasing agent in the present invention is used with nitrogen as propellant is canned, and pressure inside the tank is 0.3-0.5MPa.
A kind of preparation method of above-mentioned long effective environmental protection type releasing agent, it is characterised in that comprise the following steps：
After weighing each component, deionized water is heated in water-bath 45-55 DEG C, it is initially charged OTAC to be dissolved, and be sufficiently stirred for, it is subsequently adding graphite particulate and the stirring of PTFE particles is abundant, it is eventually adding remaining medicament, stop heating and persistently stir, liquid temp to be mixed dropped to and be distributed into after room temperature in pressurized tank, and pour high pure nitrogen makes pressure inside the tank reach 0.3-0.5MPa as propellant, you can.
The using method of releasing agent of the present invention is very easy, concrete operation method be after mould is heated to 60 DEG C -80 DEG C as needed with equipped with releasing agent aerosol can die surface is carried out even application 1-2 all over.
Compared with prior art, the present invention has the following advantages：
Releasing agent of the present invention sprays to and redox reaction occurs after heated die surface, one layer of laminated film is formed in die surface, this layer film strength is attached to die surface, and the thickness of film is below 0.5 micron, and mould and die accuracy will not be had any impact.The laminated film does not contain in addition to deionized water and propellant high pure nitrogen are evaporated the various organic solvents in traditional releasing agent in forming process, has prevented the healthy harm to operating personnel, complies fully with the requirement of environmental protection.
The laminated film that formed in use of the present invention have do not glue, self-lubricating, coefficient of friction are low, wear-resisting, corrosion resistant excellent properties; hardness can reach HRC50, therefore can not only play the demoulding effect of brilliance mould can also be played a part of to protect and increase the service life.
The laminated film and the adhesion-tight of die surface, by ASTM tests 4B grades can be reached.Therefore perfectly solve traditional releasing agent easily to transfer the pollution the defect of product.So more suitable for use in the field of the high requests such as optical goods, medical article or food compositions.
The laminated film heat resisting temperature that releasing agent of the present invention is formed can reach 350 DEG C, be not in the phenomenon failed because of charing under the molding technological condition of common plastic cement, and its excellent release property can be played for a long time after once spraying.
Releasing agent of the present invention is simple to operate when using, economical and practical, is suitable to promote.
【Description of the drawings】
Fig. 1 is the structural representation that the present invention is formed in die surface.
【Specific embodiment】
The present invention is described in further detail with reference to specific embodiment：
