Environmentally friendly and degradable aromatic polyurethane foam material and preparation method thereof

Abstract

The invention specifically discloses an environmentally friendly and degradable aromatic polyurethane foaming material, which is formed by mixing and foaming components A and B, wherein: component B is aliphatic isocyanate, and component A includes the following parts by weight Components: 80-100 parts of complex polyol, 4-8 parts of foaming agent, 0.5-0.8 parts of catalyst, 0-1 part of cross-linking agent, 0.5-1 part of foam stabilizer and 15-25 parts Parts of modified lavender particles, wherein the complex polyol is composed of vegetable oil-based polyether polyol, polypropylene oxide ether and polyurethane insole alcoholysis product. The invention adopts modified lavender granules, which can effectively control the volatilization of lavender aroma components, achieve long-lasting aroma effect and cover up peculiar smell, and at the same time enhance the antibacterial performance of foam materials and products, and have the functions of deodorization, breathability, refreshing, and aromatherapy. The advantages of repelling insects can improve the utilization rate of lavender, reduce the waste of waste and improve the degree of degradation, which is green and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of foaming materials, and in particular relates to an environmentally friendly and degradable aromatic polyurethane foaming material and a preparation method thereof. Background technique [0002] Polyurethane foam is a high molecular polymer made of isocyanate and polyether as the main raw materials, mixed by special equipment under the action of various additives such as foaming agent and catalyst, and foamed on-site by high-pressure spraying. Polyurethane sponge has a more or less pungent odor of chemical materials, part of which is the smell of ammonia, which will irritate people who use the product and affect people's comfort. [0003] Lavender, known as the "King of Herbs", has a fresh and elegant aroma and mild nature. It is recognized as the most calming, soothing and hypnotic plant. It can relieve tension, calm the mind, calm the mind, and relieve stress. Made into sachets, it can replace camphor b...
