Production technology and equipment for thermal insulating and flame-retardant wall

Abstract

The invention discloses a production technology and equipment for thermal insulating and flame-retardant wall. The production technology includes: step 10, heating polyisocyanate and polyether respectively to 39-41DEG C; step 20, mixing the polyisocyanate and polyether in a volume ratio of 1:1.1-1.6, and conducting stirring to obtain a foaming agent; step 30, heating a substrate profile to 39-41DEG C; step 40, jetting the foaming agent evenly onto the substrate profile surface to form a foaming layer; step 50, sticking a flame-retardant layer on the foaming layer to obtain a semi-finished product; and step 60, drying the semi-finished product to obtain a finished product. The obtained foaming agent has a short foaming time, which is shorter than the foaming time under room temperature by at least over one time. The rate of finished products is high, and the yield is increased by over 50% compared with the circumstance of not heating the substrate profile. At the same time, the whole production process is simple, and the production equipment is not complex, so that the process and the equipment are suitable for mass production, and the production efficiency is high.

Description

technical field [0001] The invention relates to a production process and equipment for a temperature-insulating and flame-retardant wall. Background technique [0002] Exterior wall insulation technology is widely welcomed because it does not take up interior space. The difference in material composition leads to differences in thermal conductivity and manufacturing process of thermal insulation wall panels. Some materials must be molded through dozens of processes, and some must be high-speed centrifuged or jet drawn after high-temperature melting and then prepared by molding equipment. The production process is extremely complicated. [0003] Or, for example, the Chinese invention patent publication number is CN101025042A, and the patent name is "a polyurethane thermal insulation decorative board and its production process". Pouring machine, align the mold pouring hole for polyurethane pouring, then ripen for 5-100 minutes, open the abrasive tool, take out the formed pla...

AI Technical Summary

Problems solved by technology

Since the polyurethane is poured directly at room temperature with a high-pressure pouring machine, its foaming time is slow, so it takes a long curing time; and the polyurethane is poured after the decorative material is put into the mold, so that the polyurethane and the decorative material The bonding is not tight, and even easy to fall off, the yield is low and the cost is high
