VOCs Manufacturing method of eco-friendly polyurethane roll filter foam with reduced VOCs and its filter foam

摘要

The present invention uses a specific deodorant or fragrance when manufacturing a roll filter foam using a polyurethane foam long block, and additionally performs a deodorizing process after film formation to reduce VOCs, and a method of manufacturing an eco-friendly polyurethane roll filter foam and the filter foam In the present invention, in the present invention, (A) preparing a flexible polyurethane foam foam using a slabstock method using a main material obtained by mixing polyol, isocyanate, water, and deodorant or fragrance; And, (B) the (A) Cutting the foamed foam in the width direction through a non-stop cutting to a thickness of 1 to 50 mm; And, (C) The cut foamed foam of (B) on a roll of 400 to 1200 mm in diameter and 15 to 300M in length Rolling in the form of a roll product and placing the roll with foamed foam inside the forced blasting chamber; and (D) performing a forced cell opening process on the seated foamed foam of (C) And, (E) disassembling the filter foam of (D) from a roll, and performing a deodorization process of removing VOCs from the disassembled filter foam; And (F) cutting the filter foam in which the deodorization of (E) has been completed, and then wrapping the cut filter foam with vinyl or non-woven fabric; and The filter foam is disclosed.
