Abstract

The invention discloses a device for preparing melamino-formaldehyde resin and belongs to the technical field of chemical equipment. The device comprises a mixed material bin, a material pump, a first screw machine, a stirring reactor and a second screw machine which are connected in sequence, wherein the mixed material bin is connected with a melamine high-level bin, a paraformaldehyde high-level bin and an alkali liquor high-level bin, an auxiliary material inlet is formed in the feeding end, middle position or tail end of the first screw machine, the discharge outlet end of the first screw machine is connected with a feed inlet of the stirring reactor, the feed inlet end of the second screw machine is connected with the discharge outlet end of the stirring reactor, and the second screw machine is higher than the horizontal height of the first screw machine. When the production device is applied to melamine resin production, raw material utilization rate is high, energy consumption is low, yield is high, three wastes are not generated, melamine resin with stable quality can be produced continuously, and melamine resin quality is high.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a device for preparing melamine-formaldehyde 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 p...
