Environment-friendly degradable aromatic polyurethane foaming material and preparation method thereof

Abstract

The invention particularly discloses an environment-friendly degradable aromatic polyurethane foaming material. The foaming material is formed by mixing and foaming a component A and a component B, wherein the component B is aliphatic isocyanate, and the component A comprises the following components in parts by weight: 80 to 100 parts of composite polyol, 4 to 8 parts of a foaming agent, 0.5-0.8parts of a catalyst, 0 to 1 part of a crosslinker, 0.5 to 1 part of a foam stabilizer and 15 to 25 parts of modified lavender particles; wherein the composite polyol consists of plant oil-based polyether polyol, polypropylene oxide ether and polyurethane insole alcoholysis product. According to the invention, the modified lavender particles are adopted; wherein the lavender antibacterial foam material can effectively control volatilization of lavender aroma components, so that the material achieves lasting aroma efficacy, covers peculiar smell, can enhance the antibacterial performance of thefoam material and products. The material has the advantages of odor removal, ventilation, refreshing, incense and insect expelling and the like, can improve the utilization rate of lavender, reduce waste and improve the degradation degree, and is green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of foam materials, and in particular relates to an environmentally friendly and degradable aromatic polyurethane foam 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 auxiliary agents such as foaming agent and catalyst, and foamed by high pressure spraying on site. Polyurethane sponges have more or less the pungent odor of chemical materials, and part of the odor is the smell of ammonia. The odor 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 breath, relieve stress and other effects. It can be us...

AI Technical Summary

Problems solved by technology

[0005] However, the aroma of lavender powder volatilizes quickly, there is a problem of lasting effect, and the degradability is not good at the same time

In addition, polyurethane sponge has more or less pungent odor of chemical materials, part of which is the smell of ammonia gas, which will irritate people who use the product and affect people's comfort
