Problems solved by technology

[0005] Moreover, the plant of Chrysanthemum chrysanthemum has a strange smell in its body. Cattle and sheep do not eat it, so there is no economic value. In the later stage of the plant, the tree is large and the roots are deep. It is very difficult to manually pull it out. Without the drive of economic interests, it is costly and difficult to pull it out only relying on the government to encourage it. Big

Embodiment 1

[0030] A method for manufacturing an environment-friendly home improvement building material board by using chrysanthemum stalks and birch shavings, comprising the following steps:

[0031] (1) After drying the chrysanthemum stalks, pulverize them through an 80-mesh sieve with a pulverizer, immerse them in a sodium hydroxide solution with a mass concentration of 1.2% for 8 hours, take them out and drain them, and then immerse them in an acetic acid solution with a mass concentration of 1% for 4.5 hours. After drying until the water content is 16%, it is added to the gas explosion device through the feed port, and the water vapor at 185°C enters the gas explosion device from the steam pipe, pressurized to 7MPa, kept for 3 minutes after heat preservation and pressure release, and exploded to obtain Chrysanthemum chrysanthemum Powder;

[0032] (2) Grind the birch wood shavings to a length of 1-2mm and a width of 0.1-0.5mm. At room temperature, first soak them in a hydrogen peroxi...

Embodiment 2

[0036] A method for manufacturing an environment-friendly home improvement building material board by using chrysanthemum stalks and birch shavings, comprising the following steps:

[0037] (1) After drying the chrysanthemum stalks, crush them through an 80-mesh sieve with a pulverizer, immerse them in a sodium hydroxide solution with a mass concentration of 0.5% for 10 hours, take them out and drain them, and then immerse them in an acetic acid solution with a mass concentration of 1.2% for 6 hours, and let them air naturally After drying until the water content is 15%, it is added into the gas explosion device through the feed port, and the water vapor at 180°C enters the gas explosion device through the steam pipe, pressurized to 8MPa, kept at the pressure for 3 minutes, and then released and exploded to obtain yellow top inulin body;

[0038] (2) Grind the birch shavings to a length of 1-2 mm and a width of 0.1-0.5 mm. At room temperature, first soak them in a hydrogen per...

Embodiment 3

[0042] A method for manufacturing an environment-friendly home improvement building material board by using chrysanthemum stalks and birch shavings, comprising the following steps:

[0043] (1) After drying the chrysanthemum stalks, pulverize them through an 80-mesh sieve with a pulverizer, immerse them in a 0.8% sodium hydroxide solution for 5 hours, take them out and drain them, and then immerse them in a 1.1% acetic acid solution for 5.5 hours. After drying until the water content is 18%, it is added into the gas explosion device through the feed port, and the water vapor at 180°C enters the gas explosion device from the steam pipe, pressurized to 6.5MPa, kept for 3 minutes after heat preservation and pressure release, and exploded to obtain Yellow top chrysanthemum powder;

[0044] (2) Grind the birch shavings to a length of 1-2 mm and a width of 0.1-0.5 mm. At room temperature, first soak them in a hydrogen peroxide solution with a mass concentration of 15% for 2 hours, a...

Abstract

The invention provides a method for manufacturing an environment-friendly household building material board by using yellow top chrysanthemum straws and birch shavings, and relates to the field of household building materials; the method comprises the following steps: (1) treating yellow top chrysanthemum straws with sodium hydroxide solution, taking out, draining, soaking in water vapor of 180-200 DEG C in acetic acid solution, pressurizing to 5-8 MPa, keeping the temperature and the pressure for 3 minutes, and then carrying out pressure relief blasting to obtain the yellow top chrysanthemumpowder body; (2) soaking the birch shavings in hydrogen peroxide solution at room temperature, and treating the birch shavings with steam at 160-180 DEG C for 5-20min to obtain birch fiber; (3) preparing an adhesive; (4) adding the yellow top chrysanthemum powder body and the birch fiber into a proper amount of deionized water to prepare paste, adding the paste into a mould, prepressing for 10-15sunder 1.5MPa to obtain prepressing plates, uniformly coating a layer of the adhesive between the two prepressing plates, prepressing for 10-20s under 2-5MPa, uniformly raising the temperature and pressurizing to 150-160 DEG C within 100s, 10-15MPa hot pressing for 200-250s, cooling to obtain a plate blank, finishing, curing and cutting to obtain a finished product. The method has the advantages of excellent performance, is green and environmentally friendly, and can be widely used in the market.

Description

technical field [0001] The invention relates to the field of home decoration building materials, in particular to a method for manufacturing environment-friendly home decoration building material boards by using chrysanthemum straw and birch shavings. Background technique [0002] Chrysanthemum chrysanthemum is an annual herbaceous plant with a plant height of 20-100 cm, and the highest can reach about 3 meters. The stem is upright, purple, with short hairs on the stem, the leaves are alternately opposite, oblong, with sparse and neat serrations on the edge of the leaf, and 3 parallel veins at the base. The inflorescences on the top of the main stem and side branches are gathered into scorpius cymes densely at the top, the corolla is bright, the flowers are bright yellow, very eye-catching, and the flowering and fruiting period is from summer to autumn. It has a well-developed root system, salt-alkali tolerance, barrenness tolerance, strong stress resistance, and an astonis...
