Abstract

The invention relates to a method for continuously producing an ultra-thick phenolic aldehyde outer wall heat-preservation board. The method comprises the following steps: adding a foaming agent, a fire retardant and a surfactant into phenolic aldehyde resin; controlling the temperature to be kept at 15-20 DEG C; sufficiently agitating in a material storage tank, mixing with a curing agent according to a ratio, and injecting into a laminating machine; uniformly spreading coating materials on upper and lower chain plates of the laminating machine; covering a side surface with side paper; backwards conveying by the chain plates; and finally, incising and cutting to prepare the ultra-thick phenolic aldehyde outer wall heat-preservation board. Compared with the prior art, heat burning and un-filled foaming problems in the production process of the ultra-thick phenolic aldehyde outer wall heat-preservation board are solved, and the production efficiency is also improved.

Description

technical field [0001] The invention belongs to the field of thermal insulation of building exterior walls, and in particular relates to a method for continuously producing ultra-thick phenolic exterior wall thermal insulation boards. Background technique [0002] The basic thickness of ordinary phenolic external wall insulation boards is less than 60mm, and its thermal resistance is less than 1.8. In low temperature environments, such as winter in the north, the thermal resistance of external wall insulation is far from enough. The thermal conductivity of the phenolic foam board and increase the thickness of the insulation board. The thermal conductivity of modified phenolic foam boards on the market can generally reach 0.028W / m·K, but it is very difficult to continue to reduce it, so it is not obvious to increase its thermal resistance. [0003] The production process of phenolic external wall insulation board is also a heat release process, and when the thickness is more...
