AI Technical Summary
Technical Problem
Existing pulp molded tableware is expensive, has poor water and oil resistance, and lacks antibacterial function.
Method used
Water-resistant and oil-resistant pulp molded tableware is prepared using sugarcane bagasse and lotus stem residue as the main raw materials, combined with alkyl ketene dimer waterproofing agent and long-chain alkane mixed oil-proofing agent through mechanical beating, vacuum water absorption and high temperature and high pressure molding processes.
Benefits of technology
The mechanical strength, impermeability and antibacterial properties of tableware are significantly improved. After soaking the tableware in 80℃ hot water for 24 hours, the water absorption rate is ≤0.5%, and the oil resistance level reaches level 9.

Abstract
The invention relates to water-resistant and oil-resistant paper pulp molded tableware based on bagasse paper pulp and lotus stem residues and a preparation method of the water-resistant and oil-resistant paper pulp molded tableware. Research finds that bagasse and lotus stem residues are used as raw materials to be compounded for use, an oil-proofing agent and a waterproof agent are added, lotus stem residue powder with high cellulose content is used as a raw material to achieve a synergistic effect with bagasse, the filling property and formability of the slurry are enhanced, and meanwhile, the lotus stem residue powder has high porosity, so that the filling property and formability of the slurry are improved. The antibacterial agent is beneficial to adsorption of a water-proofing agent and an oil-proofing agent, is beneficial to improvement of the barrier property of the molded tableware, and contains polyphenol antibacterial substances, so that the safety of the molded tableware is improved.
