Problems solved by technology

[0005] On the other hand, the polyurethane automotive cushions currently produced in China cannot meet the antibacterial requirements, so they can only be used in the low-end automobile market or other markets that do not require high antibacterial requirements.
The preparation of antibacterial automobile buffer blocks in the world originated in the 1990s, mainly based on inorganic silver ion antibacterial agents and organic vanillin antibacterial agents. However, these antibacterial agents are poor in heat resistance, easy to hydrolyze, and have a short validity period. High-end automotive market needs

Abstract

The invention discloses a preparing method of a high-performance polyurethane buffer cushion. The preparing method sequentially comprises the steps of antibiosis polyol preparing, prepolymer preparing, blending, casting moulding and vulcanizing. In the step of antibiosis polyol preparing, polyester polyol from plants is adopted, and self-made traditional Chinese medicine antibiosis composition is added in the preparing process. In the step of prepolymer preparing, low-single-alcohol polyol is adopted as polyether polyol, and nano glass micro powder and modified isocyanate are added in the preparing process. The raw materials for preparing the high-performance polyurethane buffer cushion mostly stem from the plants, and therefore the environment load can be reduced for responding to the social tendency facing the global environment protection recently. The high-performance polyurethane buffer cushion has balanced hardness, rebound resilience, superior durability and good antibacterial capability.

Description

technical field [0001] The invention relates to the field of buffer materials, in particular to a preparation method of a high-performance polyurethane buffer pad. Background technique [0002] In recent years, from the viewpoint of reducing environmental load, plant-derived resins obtained from plant resources have been sought instead of petroleum-derived resins that use petroleum resources as raw materials. That is, the plant-derived resin absorbs CO in the air from one side 2 , while forming raw materials obtained by photosynthetically growing plants, corresponding to CO even through post-use combustion processing 2 emitted into the atmosphere, the result also does not lead to atmospheric CO 2 Therefore, it is attracting attention as a material that contributes to reducing the environmental load. [0003] Polyurethane is a typical carbon-neutral resin. As the polyol component used as a raw material for polyurethane, polyols represented by petroleum-derived polyether po...
