The invention discloses a melamine resin continuous production device and belongs to the technical field of chemical equipment. The melamine resin continuous production device comprises a mixture stock bin, a material pump, a first screw machine, a stirring tank and a second screw machine. The mixture stock bin is respectively connected to a paraformaldehyde high-position bin and an alkali liquid high-position bin. The length of the first screw machine is in a range of 5-7m. A melamine feed inlet is arranged at a position 0.5-1m away from the first screw machine. A discharge outlet of the first screw machine is connected to a feeding inlet of the stirring tank. A feeding inlet of the second screw machine is connected to a discharge outlet of the stirring tank. The second screw machine is higher than the horizontal height of the first screw machine. In melamine resin production, the production device has a high raw material utilization rate, low energy consumption and a high yield, does not produce three wastes and can continuously produce melamine resin with stable quality. The melamine resin product has good quality.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a continuous production device of melamine resin. Background technique [0002] Melamine resin, also known as melamine-formaldehyde resin, is a polymer obtained by the reaction of melamine and formaldehyde. A cross-linking reaction occurs during processing and molding, and the product is an infusible thermosetting resin. It is customary to call it amino resin together with urea-formaldehyde resin. [0003] Melamine resin can be made into melamine formaldehyde foam after foaming reaction. This foam is non-flammable, water-resistant, heat-resistant, aging-resistant, arc-resistant, chemical-resistant, and has good insulation performance, gloss and mechanical strength. Good sound absorption. Therefore, it is widely used in sound-absorbing and flame-retardant buildings, automobiles, aircraft carriers, submarines, etc. [0004] At present, the existing melamine resin pro...
