Embodiment 1

[0019] Embodiment 1: A method for preparing a composite floor using crop stalks: specifically comprising the following steps:

[0020] (1) collecting wheat stalks or corn stalks in the air and drying them, and when the moisture content in the stalks is reduced to 10%, pulverize them and pulverize them into granules;

[0021] (2) Feed the straw granules into the tea frying machine and fry them at a temperature of 60°C for 10 minutes. Sprinkle salt powder continuously during the frying process, wherein the amount of salt powder sprinkled is 1% of the total mass of the straw granules ;

[0022] (3) Feed the stalk after frying into the pulverizer for pulverization, and pulverize it into a powder with a mesh number of 300;

[0023] (4) Take 800 parts by mass of straw powder, put it into the reaction kettle, and add 50 parts of calcium carbonate, 80 parts of carbon powder, 40 parts of foaming agent, 10 parts of lubricant and 15 parts of Stabilizer, carry out sealed stirring reacti...

Embodiment 2

[0026] Embodiment 2: A method for preparing a composite floor using crop stalks: specifically comprising the following steps:

[0027] (1) collecting wheat stalks or corn stalks in the sun and drying, and when the moisture content in the stalks is reduced to 20%, it is crushed and crushed into granules;

[0028] (2) Feed the straw granules into the tea frying machine and fry at a temperature of 80°C for 10 minutes. Sprinkle salt powder continuously during the frying process, wherein the amount of salt powder sprinkled is 1% of the total mass of the straw granules ;

[0029] (3) Send the stalk after frying into the pulverizer for pulverization, and pulverize it into a powder with a mesh number of 400;

[0030] (4) Take 800 parts by mass of straw powder, put it into the reaction kettle, and add 50 parts of calcium carbonate, 80 parts of carbon powder, 40 parts of foaming agent, 10 parts of lubricant and 15 parts of Stabilizer, carry out sealed stirring reaction together, stop ...

Embodiment 3

[0033] Embodiment 3: A method for preparing a composite floor using crop stalks: specifically comprising the following steps:

[0034] (1) Collecting wheat stalks or corn stalks to dry in the sun and drying, and when the moisture content in the stalks is reduced to 10-20%, crush them into granules;

[0035] (2) Feed the straw granules into the tea frying machine and fry at a temperature of 70°C for 10 minutes, and sprinkle salt powder continuously during the frying process, wherein the amount of salt powder sprinkled is 1% of the total mass of the straw granules ;

[0036] (3) Feed the stalk after frying into the pulverizer for pulverization, and pulverize it into a powder with a mesh number of 350;

Abstract

The invention provides a preparation method for a composite floor by using crop straw, and relates to the technical field of composite floor preparation methods. Wheat straw or maize straw or other straw is collected, aired, dried and then crushed, straw pallets are stir-fried, salt powder is scattered in the stir-frying process, stir-fried straw is crushed, straw powder is taken out and fed into a reaction still, calcium carbonate, carbon powder, foaming agents, lubricants and stabilizers are added and subjected to a sealed stirring reaction together with the straw powder, the reaction still is warmed up after stirring is stopped, stirring is continued, after stirring, the mixture is fed into hot plastic flooding machine equipment for thermoplastic extrusion to form a floor shape and then is fed into a cooling tank for cooking shaping, and then cutting is conducted. The crop straw can be recycled through the preparation method; the preparation method has the advantages that production cost is reduced, composite floor types are increased, and the problem of air pollution caused by large area incineration of straw is also solved effectively, the requirement for environment protection can be met, and improvement of the overall performance and market competitiveness of the composite floor is facilitated.

Description

[0001] Technical field: [0002] The invention relates to the technical field of preparation methods of composite floors, in particular to a method for preparing composite floors by using crop straws. [0003] Background technique: [0004] Laminate flooring is a floor made of composite materials. It has the same processing characteristics as wood. It can be sawed, drilled, and nailed with ordinary tools. It is very convenient and can be used like ordinary wood. At the same time, it has the woody feeling of wood and the water-resistant and anti-corrosion properties of plastic, making it an excellent and durable outdoor waterproof and anti-corrosion building material. [0005] However, crop straws cause a lot of air pollution due to incineration every year. This patented technology provides a method of using crop straws to prepare composite flooring, which can effectively help to use crop straws, reduce straw burning, and introduce a new type of composite flooring. floor.
