Problems solved by technology

If lignin is directly mixed with polyol and foamed, due to the poor dispersion and stability of lignin in polyurethane (PU), the more the amount added, the worse the compressive strength will be.
As far as sulfonate lignin is concerned, lignin can be modified by ion exchange and then dissolved in polyol for foaming. However, modifying lignin by ion exchange will greatly increase the cost of lignin
This greatly limits the technology

Embodiment 1

[0042] The alkali-soluble lignin of 45g is added in the polypropylene glycol (PPG400) of 82.1g, utilize grinding disperser to disperse after 30 minutes, add the surfactant A of 2.4g (have the structure shown by formula 1, x / y=12.02 ), 0.11g of catalyst (the mixture of tin catalyst and amine catalyst) and 4g of blowing agent (water) and mix well. Thereafter, 137 g of polymethylene diphenyl diisocyanate (polymeric methylene diphenyl diisocyanate, PMDI) was added to perform foaming.

Embodiment 2

[0044] The same preparation method as in Example 1 was employed except that Surfactant B (having a structure represented by Formula 1, x / y=8.98) was used instead of Surfactant A.

Embodiment 3

[0046] The same preparation method as in Example 1 was employed except that Surfactant C (having a structure represented by Formula 1, x / y=5.64) was used instead of Surfactant A.

Description

technical field [0001] The invention relates to a biological polyol composition and a biological polyurethane foam material. Background technique [0002] Due to the anxiety of insufficient storage and supply of petroleum raw materials, the problems of soaring petrochemical prices and insufficient sources of petrochemical raw materials have become increasingly serious. In addition, a large amount of pollutants are also produced during the production, use, and disposal of petrochemical products, causing many environmental problems. Therefore, advanced countries in the world have listed plant-based biomaterials as a vigorous development project, and will replace petrochemical raw materials as important key industrial raw materials in the future. In nature, the reserves of lignin are second only to cellulose, and the global production is about 50 billion tons per year. Lignin, which is rich in reserves and low in cost, has great business opportunities. In addition, lignin has ...
