Method for increasing fragrance of polyurethane foaming product

Abstract

The invention belongs to the technical field of a polyurethane foaming product, and specifically relates to a method for increasing the fragrance of the polyurethane foaming product. The method comprises the following steps: matching basic raw materials of a polyurethane foaming raw material, adding essence which is ground into powder in the polyurethane foaming raw material, and carrying out primary mixing, thus obtaining a foamed mixture; putting the obtained foamed mixture into a polyurethane foaming machine, and starting to fully mix and foam; introducing an aromatic gas into the polyurethane foaming machine, enabling the aromatic gas to enter the polyurethane foaming machine and foam together with the foamed mixture, and enabling foam in the foamed mixture to be full of the aromatic gas; after completing the foaming of the foamed mixture, preparing a product by utilizing a foamed product. According to the method disclosed by the invention, by adding the powdery essence in the polyurethane foaming raw material, the prepared polyurethane foaming product has the fragrance; by introducing the aromatic gas into the polyurethane foaming machine, the aromatic gas enters the polyurethane foaming machine so as to foam together with the foamed mixture, and the prepared polyurethane foaming product is enabled to have the fragrance.

Description

technical field [0001] The invention belongs to the technical field of polyurethane foam products, in particular to a method for increasing the fragrance of polyurethane foam products. Background technique [0002] Polyurethane rigid foam is a high molecular polymerization made of isocyanate and polyether as the main raw materials, mixed by special equipment, and foamed on-site by high-pressure spraying under the action of various additives such as foaming agent, catalyst, and flame retardant. things. There are two types of polyurethane foam, soft foam and hard foam. Soft foam has an open-cell structure, and hard foam has a closed-cell structure; soft foam is divided into two types: crusted and non-skinned. [0003] The main function of polyurethane soft foam is cushioning. Polyurethane soft foam is commonly used in sofa furniture, pillows, cushions, toys, clothing and sound insulation linings. Polyurethane rigid foam is a new type of synthetic material with thermal insu...
