Description
Technical field
The utility model relates to silicon rubber technical field, refers to especially a kind of silicon rubber production unit.
Background technology
Organosilicon material refers to polysiloxane compounds, and its molecular structure had both contained organic group, contains again inorganic structure, and this special composition and molecular structure make it integrate the function of organic characteristic and inorganics.Compare with other macromolecular materials, the outstanding properties of organosilicon product is good heatproof characteristic (60 ℃～250 ℃), electrical insulation capability, its dielectric loss, proof voltage, resistance to electric arc, resistance to corona, volume resistivity and surface resistivity etc. all come out at the top in insulating material.This material can reach decades in work-ing life under physical environment, and its resistance to biological aging without rejection, has good anticoagulation function with animal body, so the Application Areas of organosilicon material also comprises sealing, encapsulation, bonding etc.
The development of organosilicon material is keeping higher speed always, and market mainly concentrates on the U.S., Europe, San Ge region, Asia, and nineteen forty-seven is 1000 tons, to 2005, has reached 1,500,000 tons.
Silicone adhesive english name is SILICONE, is organosilicon material product, and the bonding force of silicone glass cement is strong, and tensile strength is large, has again weathering resistance, vibration resistance simultaneously, and moistureproof, anti-foul smell and adapt to the feature that cold and hot variation is large.In addition its suitability more widely, can realize bonding between most of building material products, so using value is very large.Produce silicone adhesive except 107 gum, in other constituents, the overwhelming majority is powder, and powder is nano level, and adularescent, black also have other pigment.
The opening for feed of existing reactor is generally a larger ring flange, generally, by operator, directly packed powder is directly rendered to reactor inside by opening for feed, this feeding mode flour dust overflow is the most serious, on the infringement of environment be also maximum on the healthy impact of operator; Existing feeding mode also has and to feed intake by transmission rig, because reactor opening for feed is standard interface, that can not seal with transmission rig is connected, therefore this mode feeds intake and when being transferred to opening for feed, has equally the problem of flour dust overflow, and just impact is slightly less than the direct input of operator.
In the production or reaction process of existing silicon rubber, all need to add the raw material of powder, in powder adition process, have a large amount of flour dust overflows, cause the waste of material, excessive dust can affect operating environment health simultaneously, and can cause damage to operator's health.Also the device that has at present vacuum suck charging, but these devices do not have for silicon rubber preparation field, and current vacuum absorption device can not continuous charging.
In the production or reaction process of existing silicon rubber, need use DMC, DMC is dimethyl ring siloxane mixture, chemical formula is [(CH3) 2SIO] n, n=3, 4, 5, 6 Primary Speciation dimethyl ring body siloxanes are to take dimethyldichlorosilane(DMCS) as main raw material, through hydrolysis, silica (Si-O) key of take is main chain, on Siliciumatom, directly connect the organic and inorganic compound of organic radical, Primary Speciation dimethyl ring body siloxane molecule structure presents ring-type, mainly comprise hexamethyl cyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), decamethylcyclopentaandoxane (D5), ten diformazan basic ring six siloxanes (D6), hexamethyl cyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), decamethylcyclopentaandoxane (D5), ten diformazan basic ring six siloxanes (D6) content reach more than 50% water white transparency or milky white liquid, flammable, free from extraneous odour, water insoluble, be dissolved in the organic solvents such as benzene.Be mainly used in carrying out silicone oil, silicon rubber and the silicone resin etc. that ring-opening polymerization becomes different polymerization degree.DMC is liquid material, in reaction process, in order to determine the abundant reaction of another kind of reactant, the DMC adding is excessive adding, in reacted silicon rubber, DMC has residue, existing treatment process normally by the silicon rubber of preparation and unnecessary DMC simultaneously from material outlet take out and transfer to container, carry out separated, DMC after separation can add reactor for the preparation of the reaction of silicon rubber again, the separation of this DMC and again utilize cumbersome, waste a large amount of human and material resources, and efficiency is not high.
The production reaction raw materials used of existing silicon rubber, need to be kept in 17 ℃ of above environment, if the environment of preserving, lower than 17 ℃, easily freezes or caking, is unfavorable for follow-up reaction while preparing silicon rubber.In the lower region of temperature or winter, also need these raw materials to be additionally incubated processing, existing preserving type is all kept at material in kiln or moist closet, at kiln or inner the increasing of moist closet, regulates the device of temperature to regulate, and this mode need to additionally provide the energy.The steam of reactor is after heating reactor, and the secondary steam of discharging by Jacket outlet also has the temperature of 60 ℃ of left and right, and the processing mode of existing secondary steam is all directly emptying substantially, causes the waste of the energy.
