Abstract

The invention discloses a manufacturing method of a flame-retardant non-woven fabric for external wall heat preservation, and relates to the technical field of external wall heat preservation, and the manufacturing method of the flame-retardant non-woven fabric for the external wall heat preservation comprises the following specific manufacturing steps: step 1, soaking the non-woven fabric in a magnesium hydroxide solution until the interior of the non-woven fabric is completely soaked; step 2, fully extruding the soaked non-woven fabric, and naturally airing the non-woven fabric after the non-woven fabric is extruded; and step 3, placing the aired non-woven fabric in a drying oven for heating and baking, so that a magnesium oxide film can be formed on the surface of the non-woven fabric. The flame-retardant manufacturing method of the external wall heat-insulation non-woven fabric is mainly used for heat insulation of an external wall, the manufacturing method is simple, the manufacturing cost is relatively economical, the flame-retardant and heat-insulation effects can be effectively achieved, the flame-retardant and heat-insulation effects are permanent and effective, and serious safety accidents such as fire disasters caused by heat insulation failure of a building are avoided.

Description

technical field [0001] The invention relates to the technical field of external wall thermal insulation, in particular to a method for producing a flame retardant non-woven fabric for external wall thermal insulation. Background technique [0002] With the improvement of the construction standards of building exterior walls, more and more exterior walls need to be equipped with thermal insulation measures. Most of the existing external wall insulation is covered with new type of insulation material, but the production cost of the insulation material is high, the process is more complicated, and the insulation material contains organic components, which are prone to deterioration after a long time, and then affect the insulation effect. . SUMMARY OF THE INVENTION [0003] The present invention proposes a method for producing flame-retardant non-woven fabrics for thermal insulation of external walls, so as to solve the above-mentioned problems in the background technology. ...
