Embodiment 1

[0043] The raw materials provided in this example are composed of 16 parts of bamboo, 12 parts of bagasse, 15 parts of straw, 18 parts of cotton husks, 8 parts of corn stalks and 8 parts of tea stalks according to the parts by mass.

[0044] In this embodiment, the additive amounts of the binder, the lubricant and the waterproofing agent are: 2%, 2.5%, and 1.5% by weight.

[0045] The binder used in this example is oxidized modified starch, the lubricant is a mixture of glycerin and silicone in a mass ratio of 1 to 1.5:1, and the waterproofing agent is anhydrous sodium carbonate and hydroxymethyl cellulose in a mass ratio of 1:1 mixture.

Embodiment 2

[0047] The raw materials provided by the embodiment of the present invention are composed of 18 parts of bamboo, 14 parts of bagasse, 19 parts of rice straw, 22 parts of cotton husks, 10 parts of corn stalks, and 10 parts of tea stems according to the parts by mass.

[0048] In this embodiment, the additive amounts of the binder, the lubricant and the waterproofing agent are: 4%, 2%, and 1.5% by mass.

[0049] The adhesive used in this embodiment is polyvinyl alcohol. The lubricant is a modified zinc stearate emulsion. The waterproofing agent is a 1:1 mass mixture of anhydrous sodium carbonate and stearic acid.

Embodiment 3

[0051] The raw materials provided by the embodiment of the present invention are composed of 17 parts of bamboo, 13 parts of bagasse, 17 parts of rice straw, 20 parts of cotton husks, 9 parts of corn stalks and 9 parts of tea stems according to the parts by mass.

[0052] In this embodiment, the additive amounts of the binder, the lubricant and the waterproofing agent are: 4.5%, 1.5%, and 1% by weight.

[0053] The adhesive used in this embodiment is carboxylated styrene-butadiene latex. The lubricant is polyethylene glycol. The waterproofing agent is a 1:1 mass mixture of anhydrous sodium carbonate and stearic acid.

[0054] The pulp molded products obtained in the above examples are green and environmentally friendly degradable materials, which can be directly discarded and naturally degraded into planting soil after being discarded; Spraying chemicals such as water-repellent agent on the surface after the blank is formed and before drying can greatly reduce the amount of ...

Abstract

The invention discloses an environment-friendly molded pulp formation method. The method comprises the steps that raw materials are subjected to impurity removal, sterilization, soaking and boiling, and a hydrapulper is used for conducting smashing to obtain a smashed material; the treated smashed material is defibered for obtaining an even pulp; the mixed pulp is prepared; a molded pulp wet blankis made; after the wet blank is formed, before the wet blank is dried, the surface of the wet blank is sprayed with a liquid-state waterproof agent; the molded pulp wet blank is dewatered, subjectedto hot press formation and cut to a molding product. The product made through the environment-friendly molded pulp formation method is an environment-friendly degradable material, and after being wasted, the material can be directly discarded and naturally degraded into soil for planting or smashed and reduced into the soil for planting for reuse or discarding; according to the method, the application quantity of chemical products is greatly lowered, and plain boiled water can also be more clean. The surface of the product is coated with the material, no chemical product exists in the product,the production cost is reduced, and the environment-friendly performance is better.

Description

technical field [0001] The invention belongs to the technical field of pulp molding production, in particular to the technical field of environment-friendly pulp molding production. Background technique [0002] Pulp molding is a three-dimensional papermaking technique. It uses waste paper, wood pulp or other plant fibers as raw materials, and molds pulp products with a certain shape by special molds on a molding machine. It has four advantages: 1. The raw materials are waste paper, wood pulp or other plant fibers, including cardboard, waste carton paper, waste white edge paper, coniferous wood pulp, hardwood pulp, bamboo pulp, bagasse pulp, etc. 2. The production process is completed by pulping, adsorption molding, drying and shaping, etc. The process is short and harmless to the environment; 3. The product can be recycled and recycled; 4. The volume is smaller than that of foamed plastics, and it is light in weight and can be recycled. Overlapping, convenient transportat...
