Embodiment 1

[0018] Distribute the foaming liquid evenly in the mold, turn on the microwave with 60% power, wait until the foaming liquid is full of the mold, reduce the microwave power to 30%, and adjust the power to 100% after about 2 minutes, 3 minutes The foam is basically formed, after passing through the transition section , enter the drying and shaping section and solidify for 30 minutes to prepare a crude melamine foam product, which is cut to obtain a melamine product.

Embodiment 2

[0020] Distribute the foaming liquid evenly in the mold, turn on the microwave with 20% power, wait until the foaming liquid is full of the mold, adjust the microwave power to 60%, and adjust the power to 100% after 2 minutes of basic crosslinking, 2 minutes The foam is basically formed, and then After passing through the transition section, drying and setting section, curing for 20 minutes, a crude melamine foam product is prepared, and the crude product is cut to obtain a melamine foam product.

Abstract

The invention relates to a preparation process of melamine foam. The preparation process mainly consists of a (foaming liquid) distributing section, a foaming section, a transition section and high-temperature crosslinking, drying and a shaping section. A crude foam product is cut and secondarily processed to prepare a melamine foam product. A special device of the foaming section consists of microwave tube sets, wherein each of the microwave tube sets can be independently controlled and used; the power of the device can be variably modulated within 10-100%; and the total microwave power is 100-500 KW, preferably 150-350 KW.

Description

technical field [0001] The invention relates to the field of new polymer materials, in particular to a preparation process and main technical parameters of a melamine foam. Background technique [0002] Melamine foam is an intrinsically high flame-retardant foam material, because of its excellent sound absorption, noise reduction, heat insulation, high temperature resistance, low smoke rate, chemical corrosion resistance, convenient post-processing, etc. Its performance makes it widely used in more and more fields such as architectural decoration, public places, electromechanical equipment, and transportation vehicles. [0003] At present, the commonly used foam materials (such as polyurethane, polystyrene, phenolic foam, etc.) not only have poor flame retardancy, but also have poor high temperature resistance, resulting in a large amount of smoke and toxic gases produced in a fire. According to statistics, more than 80% of fire deaths are related to inhalation of toxic fum...
