The invention discloses a thermoplastic starch-polyvinyl alcohol composite plastic film, and relates to the technical field of film production. The composite plastic film is made by using the following raw materials, by mass, 80-100 parts of (self-made) thermoplastic starch, 40-55 parts of polyvinyl alcohol, 10-15 parts of acrylic acid, 5-10 parts of benzoyl peroxide, 7-12 parts of oxidized polyethylene wax, 4-8 parts of hydroxyethyl cellulose, 5-12 parts of calcium stearate, 5-15 parts of iron oxide, 3-6 parts of gelatin, 5-10 parts of urea, and 8-15 parts of polyethylene glycol. The composite plastic film made in the invention reserves the good biodegradation performance of starch and effectively improves the mechanical performances of a plastic film, and a covalent bond introduced due to the addition of a cross-linking agent can substitute a hydrogen bond in order to improve the mutual crosslinking among starch, polyvinyl alcohol and other raw material molecules.

The invention aims to solve the conventional problems of lightweight refractory materials in the prior art, provides a method for preparing magnesia-based lightweight aggregates by a foaming method, and belongs to the technical field of refractory materials. The method comprises the steps: mixing oleate and an appropriate amount of water, stirring and foaming to obtain foams; adding calcium stearate into the foams to produce uniform and stable foams; adding water into magnesia powder, mixing evenly to obtain slurry, and then mixing the slurry with the foams to obtain foamed slurry; and pouringthe foamed slurry into a mold, molding, curing after molding, demolding, then drying, and then sintering a green body at high temperature. With oleate as a foaming agent, calcium stearate as a foaming stabilizer and magnesia powder as the slurry, the magnesia-based lightweight aggregates are prepared. The method can produce the lightweight aggregates with different pore sizes, and the lightweightaggregates have the advantages of high strength, high use temperature, strong corrosion resistance to reducing gas, and excellent corrosion resistance to alkali vapor, and are suitable for use in alkaline environments.
