摘要： A method of preparing biodegradable water-resistant paper utensils which includes the steps of: (a) preparing a pulp aqueous slurry at a consistency of about 4%; (b) adding surfactant to the slurry; (c) thereafter, adding between 8 and 30 percent weight of a biodegradable and water-resistant agent to the slurry to form a slurry mixture; (d) refining the slurry mixture at a consistency of about 4 percent to a desired drainage; (e) diluting the refined slurry mixture and adding an aggregating agent thereto to form a furnish; and (f) after step (e), forming the furnish to obtain biodegradable, water-resistant paper board or directly a paper utensil. The forming step can be through a hot-press at a temperature of 115.degree. to 170.degree. C.

摘要： A biodegradable and water-resistant paper product which has the compositions of 8-30% weight of a biodegradable and water-resistant agent selected from the group consisting of calcium stearate, cellulose stearate, calcium palmitate and cellulose palmitate, 92-70% weight of pulp, based on the sum of the dry weight of pulp and water-resistant agent; surfactant selected from the group consisting of rosin soap, sodium oleate, sodium stearate, and sodium palmitate; and aggregating agent as alum. The paper product is prepared by a method which includes the steps of: (a) preparing a pulp aqueous slurry at a consistency of about 4%; (b) adding surfactant to the slurry; (c) thereafter, adding between 8-30% weight of a biodegradable and water-resistant agent to the slurry to form a slurry mixture; (d) refining the slurry mixture at a consistency of about 4% to a desired drainage; (e) diluting the refined slurry mixture and adding an aggregating agent thereto to form a furnish; and (f) after step (e), forming the furnish to obtain biodegradable and water-resistant paper board or directly a paper utensil.
