Abstract
The invention relates to the field of polyurethane semi-rigid foam, in particular to semi-rigid foam and a preparation method and application thereof, and the provided semi-rigid foam comprises the following raw materials in parts by weight: 100 portions and 200 portions of isocyanate; 100 parts of a polyol composition; 0.5-5 parts of a surfactant; 0-5 parts of a crosslinking agent; 10-30 parts of water; 2-4 parts of a catalyst; 0-50 parts of a flame retardant; the polyol composition is a first polyether polyol alone or comprises the following raw materials: 30-100 parts of first polyether polyol; 0-70 parts of polyester polyol and/or second polyether polyol; the first polyether polyol is a bio-based polyol; the second polyether polyol is a polyether polyol of non-bio-based polyol; the polyol composition prepared according to the proportion is clear and transparent, has uniformity, can be placed at normal temperature for more than one year without any layering and turbidity, has more excellent physical properties, and reduces the cost.
Description
Technical Field
The invention relates to the field of polyurethane semi-rigid foam, in particular to semi-rigid foam and a preparation method and application thereof.
Background
The low-density semi-rigid foam has the advantages of high foaming ratio, small density, low cost and the like, and the semi-rigid foam with certain bearing capacity and deformability is widely applied to the field of precision instruments/article packaging.
The semi-rigid foam for packaging is generally produced by adopting a pouring method, the process comprises the steps of packaging a precision instrument/object in a plastic bag or a preservative film, pouring mixed liquid of combined polyether and isocyanate in a packaging box, enabling the mixed liquid to foam rapidly, placing the instrument in the center of the mixed liquid in the process, wrapping the instrument after foam forming, and playing a role in packaging.
Conventional semi-rigid foams for packaging are usually made by mixing a hard-foam polyether polyol with a soft-foam polyether polyol, or alternatively by mixing a hard-foam polyether polyol with a polymer polyol, using an open-cell silicone oil and/or an open-cell agent to obtain a higher open-cell content. The open-cell silicone oil and the open-cell agent directly influence the open-cell capability of the foam, the open-cell rate of the soft foam polyether polyol and the polymer polyol can also be influenced on the side surface, and the open-cell rate is often insufficient when the using amount of the soft foam polyether polyol and the polymer polyol is too low. However, the hard-foam polyether polyol and the soft-foam polyether polyol are often poor in compatibility due to large difference of molecular structures, a mixed system of the hard-foam polyether polyol and the soft-foam polyether polyol is often mixed, the compatibility of the open-cell silicone oil with the hard-foam polyether polyol and water is poor, and the cell opening agent is incompatible with the whole polyether polyol system. In addition, the polymer polyol itself is a suspended system and is easily separated. Therefore, the traditional full-water low-density spray foam formula often has poor uniformity, so that the mixing needs to be carried out again before use, the production efficiency is reduced, if the mixing is not uniform, the performance of the prepared foam can be greatly reduced, and even a corresponding foam product can not be obtained, and the full-water low-density spray foam often has low mechanical strength due to the large use of the soft-foam polyether polyol.
