Abstract
The invention provides a method to continuously produce amido foam plastic. After metered resin and metered accessory ingredient are highly emulsified and mixed through an emusion system, the mixture of the resin and accessory ingredient enters a distribution system; material of proper amount and thickness is distributed on a belt; the belt moves in a microwave foaming passage; the optimum foam quality is got by regulating microwave power, air temperature inside the frothing passage and the belt speed. The foam coming out of a foam oven continuously becomes perfect products after the foam is cut on line. The high temperature air required for foaming is provided with a hot blast environmental protection oven. The exhaust gas produced during foaming is discharged after the exhaust gas is burnt by the hot blast environmental protection oven and reaches the mark.
Description
One, the present invention relates to the continuous producing method of amino aerated plastics, especially a kind of method of continuous production amino aerated plastics.
Two, background technology: the continuous production of amino aerated plastics industrialization does not also have producer to produce.
Three, summary of the invention: the method that the purpose of this invention is to provide a kind of continuous production amino aerated plastics, it has filled up domestic blank, the objective of the invention is to realize by following consecutive steps: with melamine, formaldehyde and multiple attached material is that the amino aerated plastics produced of raw material is resin dedicated, and the mol ratio of its melamine and formaldehyde is 1: 1-1: 4.Be reacted to viscosity 100-400PaS from reactor, can cool off, feed thermostatted water in the cooling device by reacting kettle jacketing, 10-30 ℃ of thermostatted water temperature, final resin constant temperature is to 10-30 ℃.
Behind the resin constant temperature, with the metering of double helix meter, resin metering 0.5-4.5kg/min.
Emulsifying resins need add auxiliary agent, and auxiliary agent comprises emulsifying agent, blowing agent, curing agent and stabilizing agent, and emulsifying agent, blowing agent, curing agent and stabilizing agent can mix a back adding, and the auxiliary agent measuring equipment can be selected post match pump.
The auxiliary agent of metering and the resin of metering enter the emulsification shear pump resin are carried out emulsification.
The good expanding foam solution cloth of emulsification is on the end belt of foaming passage.Can select moving cloth device cloth, fabric thickness 3-60mm.
The continuous motion in microwave foaming passage of end belt, it is continuous foamed in microwave foaming passage to drive expanding foam solution.The foaming passage is to surround by four belts that are synchronized with the movement.By regulating the air themperature in belt movement speed, microwave power and the foaming passage, regulate foam density and foam quality.In the passage air themperature 25-120 ℃ of belt movement speed 0.3-2.5m/min, microwave power 15kw-180kw, foaming.
The waste gas that produces in the foaming burns back up to standard discharging by the hot blast environment-friendly stove, and the heat that the burning of hot blast environment-friendly stove produces produces hot blast by the heating fresh air and offers foaming furnace.
After foaming was finished, the belt that foam is moved was continuously delivered to foam slaking district, 100-230 ℃ of foam curing temperature.
The foam that comes out from the slaking district has been the green safety product, cuts into the size of wanting by online guillotine.
Four, the specific embodiment: the present invention realizes by following consecutive steps: with melamine, formaldehyde and multiple attached material is that the amino aerated plastics produced of raw material is resin dedicated, and the mol ratio of its melamine and formaldehyde is 1: 1-1: 4; Be reacted to viscosity 100-400PaS from reactor, can cool off, feed thermostatted water in the cooling device by reacting kettle jacketing, 10-30 ℃ of thermostatted water temperature, final resin constant temperature is to 10-30 ℃.
Behind the resin constant temperature, with the metering of double helix meter, resin metering 0.5-4.5kg/min.
Emulsifying resins need add auxiliary agent, and auxiliary agent comprises emulsifying agent, blowing agent, curing agent and stabilizing agent, and emulsifying agent, blowing agent, curing agent and stabilizing agent can mix back-piece and add, and the auxiliary agent measuring equipment can be selected post match pump.
The auxiliary agent of metering and the resin of metering enter the emulsification shear pump resin are carried out emulsification.
The good expanding foam solution cloth of emulsification is on the end belt of foaming passage.Can select moving cloth device cloth, fabric thickness 3-60mm.
The continuous motion in microwave foaming passage of end belt, it is continuous foamed in microwave foaming passage to drive expanding foam solution.The foaming passage is to surround by four belts that are synchronized with the movement.By regulating the air themperature in belt movement speed, microwave power and the foaming passage, regulate foam density and foam quality.In the passage air themperature 25-120 ℃ of belt movement speed 0.3-2.5m/min, microwave power 15kw-180kw, foaming.
The waste gas that produces in the foaming burns back up to standard discharging by the hot blast environment-friendly stove, and the heat that the burning of hot blast environment-friendly stove produces produces hot blast by the heating fresh air and offers foaming furnace.
After foaming was finished, the belt that foam is moved was continuously delivered to foam slaking district, 100-230 ℃ of foam curing temperature.
The foam that comes out from the slaking district has been the green safety product, cuts into the size of wanting by online guillotine.
