Abstract

The invention relates to a phenolic aldehyde foam double-metal-face chromatic steel sandwich plate with good toughness, comprising an upper metal face chromatic steel plate, a lower metal face chromatic steel plate and a middle phenolic aldehyde foam sandwich plate, wherein the phenolic aldehyde foam sandwich plate comprises the following formula (represented according to parts by weight in the formula): 100 of phenolic resin, 2 to 8 of levelling agent, 3 to 9 of foaming agent, 1 to 5 of catalyst, 0.5 to 1.5 of stabilizing agent and 20 to 30 of curing agent. The production technology of the phenolic aldehyde foam double-metal-face chromatic steel sandwich plate comprises the following steps: firstly, phenol, a formaldehyde solution of 37% and a barium hydroxide water solution of 20% are added into a reactor, stirring is initiated, the temperature is raised to 85 DEG C, a reaction is carried out for 4 to 5 hours at the temperature, a hydrochloric acid water solution is added till the pH value is adjusted to 6.8 to 7,circumfluence is carried out when the temperature is raised to 100 DEG C, oxalic acid is added, then decompression and concentrated dehydration are carried out, sampling is carried out to enable the viscosity of an output material to be 2500 to 3000MPa.(25DEG C), the reaction reaches the final point, and cooling and material discharge are carried out to obtain the phenolic resin.

Description

technical field [0001] The invention relates to a color steel sandwich panel and its production process, in particular to a phenolic foam double metal surface color steel sandwich panel and its continuous production process. Background technique [0002] Phenolic foam is a kind of foam plastic obtained by foaming phenolic resin. Compared with polystyrene foam, polyvinyl chloride foam, polyurethane foam and other materials that dominated the market in the early stage, it has special excellent flame retardancy. Performance, its light weight, high rigidity, good dimensional stability, strong chemical corrosion resistance, good heat resistance, flame retardant, self-extinguishing, low smoke, flame penetration resistance, no spills in case of fire, low price, is an electrical appliance , instrumentation, construction, petrochemical and other industries are ideal insulation and heat insulation materials, so it has been widely valued by people. At present, phenolic foam has become...
