Embodiment 1
[0057] This embodiment provides a wet-pressed pulp tray and a preparation method thereof, the preparation method comprising the following steps:
[0058] (1) The raw material and clear water are sequentially subjected to beating, pulping and molding treatment according to the solid-to-liquid ratio of 2:1000 to obtain wet embryos;
[0059] (2) After the wet embryo obtained in step (1) is dried, an aqueous solution of a water-based oil mixture with a concentration of 50wt% is artificially sprayed to form a protective coating, wherein the water-based oil mixture is mainly composed of synthetic resin, acrylic acid emulsion, and wax additives. , absolute ethanol and water, wherein the content of synthetic resin is 45wt%, the content of acrylic acid emulsion is 40wt%, the content of absolute ethanol is 3wt%, the content of wax additive is 4wt%, and the balance is water; The spray nozzle and the surface to be sprayed are at 90°, the uniformity of the protective coating obtained by sp...
Embodiment 2
[0062] This embodiment provides a wet-pressed pulp tray and a preparation method thereof, the preparation method comprising the following steps:
[0063] (1) The raw material and circulating water are sequentially subjected to beating, pulping and molding treatment according to the solid-to-liquid ratio of 1.5:1000. During the pulping process, toner and auxiliary agents are added, and the auxiliary agent is a binder to obtain a wet embryo;
[0064] (2) the aqueous solution of the water-based oil mixture of 40wt% is formed protective coating through mechanical spraying concentration through the wet embryo that step (1) makes, and wherein, described water-based oil mixture is mainly made of synthetic resin, acrylic acid emulsion, wax additive, no Water ethanol and water and other substances are mixed and deployed; the content of synthetic resin is 40wt%, the content of acrylic emulsion is 38wt%, the content of absolute ethanol is 2wt%, the content of wax additive is 3wt%, and the...
Embodiment 3
[0067] This embodiment provides a wet-pressed pulp tray and a preparation method thereof, the preparation method comprising the following steps:
[0068] (1) The raw material and circulating water are sequentially subjected to beating, pulping and molding treatment according to the solid-to-liquid ratio of 3:1000. During the pulping process, toner and auxiliary agents are added, and the auxiliary agent is a foaming agent to obtain wet embryos;
[0069] (2) the aqueous solution of water-based varnish of 60wt% is formed protective coating through mechanical spraying concentration on the wet embryo that step (1) makes, wherein, described water-based oil mixture is mainly made of synthetic resin, acrylic acid emulsion, wax additive, without Water ethanol and water and other materials are mixed and deployed; the content of synthetic resin is 50wt%, the content of acrylic emulsion is 45wt%, the content of absolute ethanol is 5wt%, the content of wax additive is 6wt%, and the balance ...
