Problems solved by technology

This scheme is convenient for making tableware, but the pretreatment of straw is complicated, the utilization of straw is low, the requirements for other main materials and adhesives are high, the consumption is large, and the production cost is high
There is also a process of hot pressing at a temperature of 100-160°C, but the forming and demoulding effects are not ideal.
There is also a common shortcoming in the above technical solutions, that is, the processed products are more suitable for use as disposable tableware, but if used for processing and manufacturing larger household utensils or packaging containers, the strength and rigidity are limited.

Embodiment 1

[0013] Raw materials: dry straw 10kg, waste paper 10kg, gypsum residue 4kg, water 2kg.

[0014] Crush the dry straw into particles with a size of about 3mm, and crush the gypsum slag into particles with a size of less than 1mm. Mix the two raw materials together, sprinkle them with water, and mix them evenly. 2 The next hot press molding time is 1.5 seconds, and a batch of disposable tableware moldings are made. The non-toxic ethyl cellulose solution is sprayed on the inner and outer surfaces of the batch molding to become a finished product, and the finished product can also be sprayed and decorated. pattern or other packaging processing.

Embodiment 2

[0016] Raw materials: dry straw 200kg, gypsum slag 60kg, water 15kg.

[0017] Crush the dry straw into particles with a size of about 4mm, and the gypsum slag into particles with a size of about 0.5mm. Mix the two raw materials together, sprinkle them with water, and mix them evenly. 2 The next hot press molding time is 1.5 seconds, and a batch of meal tray moldings are made. The non-toxic ethyl cellulose solution is sprayed on the inner and outer surfaces of the batch molding to become a finished product, and the finished product can also be sprayed and decorated. Pattern or other product packaging processing.

Embodiment 3

[0019] Raw materials: dry straw 20kg, waste paper 180kg, gypsum residue 80kg, water 25kg.

[0020] Crush the dry straw into particles with a size below 5mm, and crush the gypsum slag into particles with a size of about 0..3mm. Mix the two raw materials together, sprinkle them with water, and mix them evenly. 2 The next hot-press molding time is 1 second, and a batch of household trash can moldings are made. The outer and outer surfaces of the batch molding body are dip-coated with tung oil to become a finished product. The finished product can also be sprayed with decorative patterns or other product packaging processing .

Abstract

A technology for making container or board made from straw and stalk includes such steps as proportionally mixing straw and stalk with used paper, breaking, proportionally mixing it with gypsum dreg particles and water, stirring, hot die pressing, and spraying water-proofing agent on the surface of products.

Description

technical field [0001] The invention relates to a production method of disposable tableware, container and plate, in particular to a production method of making disposable tableware, container and plate by using plant straw or waste paper Background technique [0002] Due to its good degradability and low cost, plant straw has always been an important research object of degradable materials and disposable materials. Much of its research focuses on the use of straw as an alternative to plastic and paper for the production of disposable bowls, cups and boxes. Such as the Chinese patent announcement number: CN 1090468C, the announcement date was September 11, 2002, and the invention patent entitled "Process Method for Producing Disposable Tableware Boxes with Plant Straws" proposes to put crushed plant orange stalk particles into Mix cellulose, starch and edible alkali with hot water into the slurry liquid, add a coagulant, put it into a mold with a cover and press it into sha...
